  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to embodiment shown below.

In the present specification and drawings, the same reference numerals denote the same components.

(Embodiment 1)
FIG. 1 shows an example of the architecture of the communication apparatus according to the first embodiment. As shown in the figure, the difference between the device-dependent unit 110 that depends on the compliant standard and the manufacturing vendor, and the hardware (for example, hardware 111 and hardware 112) and software (for example, software 113) of the device-dependent unit 110 is concealed. The middleware 120 includes a device-independent application 130 that is a general-purpose application independent of the device. The device dependence unit 110 executes one or more functions provided in the network device. The device dependence unit 110 depends on a communication device provided therein. In other words, the device-dependent unit 110 is not compatible with other communication devices, and cannot be used as it is for newly manufactured communication devices (particularly, devices with different standards or manufacturing vendors that conform to them). The middleware 120 functions as an interface that connects the device-dependent unit 110 and the device-independent application 130. The middleware 120 also functions as an interface that connects functions included in the device-independent application 130. The device-independent application 130 is one or more applications that are executed by the information processing device of the communication device provided therein. The device-independent application 130 may be configured as an application group that is a group of a plurality of the applications. The device-independent application 130 does not depend on the communication device provided therein. In other words, the device-independent application 130 has a high compatibility with other communication devices, and can be used as it is for a newly manufactured communication device (particularly, a device that conforms to a different standard or manufacturing vendor). Specific examples of applications provided in the device-independent application 130 include an application that performs setting processing in a network device, an application that performs setting change processing, and an application that performs algorithm processing. The middleware 120 and the device-independent application 130 are connected by the device-independent API 21, and the middleware 120, the software 113 of the device-dependent unit 110 and the OAM (Operations, Administration, Maintenance) 114 are connected by the device-dependent API 23, and the middleware 120 and the NE management The control unit is connected by a device-dependent API 25. The device independent applications 130 (for example, the extended function A 131-1 and the basic function 132) are connected via the middleware 120 as necessary. In FIG. 1, an EMS (Element Management System) 140 and another device 150 are connected to the device-independent application 130 via the middleware 120. However, the EMS 140 and the other device 150 are not necessarily connected to the device independent application 130 via the middleware 120. The EMS 140 and the other device 150 may be appropriately connected to the middleware 120 as necessary. Moreover, although expressed as “connected via middleware 120”, this expression is an expression from the viewpoint of the device-independent application 130. Actually, the function-independent applications are connected to each other via the middleware 120 after the connection with the hardware.
The middleware 120 may be configured as middleware for FASA application API or middleware for FASA application API. The device-independent application 130 may be configured as a FASA application or a FASA application. Each definition will be described later. Other devices are synonymous with external devices.

  Which function is the device-dependent unit 110 and which function is the device-independent application 130 is a restriction that comes from the processing to realize the middleware 120 or the device-independent application 130 (for example, a restriction that comes from the processing capability of software) ) And the importance of the implementation of the function update frequency and unique specifications, etc., making it easy to add extended functions (original functions) flexibly and quickly by the device-independent application 130, and Realize timely provision. For example, the renewal frequency such as DBA that improves the priority processing of the main signal and the use efficiency of the line, or the one that contributes to service differentiation is recommended in order. Furthermore, it is preferable that the device-independent application 130 is selected from those having a small difference in at least one of a standard, a generation, a system, a system, a device type, and a manufacturing vendor that the device to be shared complies with.

  Optimal for at least one of compliant standards, generations, methods, systems, device types, and manufacturing vendors in order to promote generalization of functions of at least one of compliant standards, generations, methods, systems, device types, and manufacturing vendors It is not a common interface. The common interface may include unused interfaces and parameters depending on the standard, generation, method, system, device type, and manufacturing vendor that the device-dependent unit 110 complies with. The middleware 120 configured as shown in FIGS. 1 and 3, the driver of the device-dependent unit 110 configured as shown in FIGS. 4 and 5, and the vendor-dependent application configured as shown in FIGS. It is desirable to have a conversion function for converting the data so as to correspond, and a function for automatically setting corresponding to a lacking interface or parameter.

  In FIG. 1, the device-dependent unit 110 is exemplified by device-dependent software 113 such as hardware, driver, firmware, application, etc. depending on a standard or manufacturer that is compliant from the bottom, and the hardware is MAC (Media Access Control) processing. “Hardware (MAC) 112” that performs the above and “Hardware (PHY) 111” that performs from physical layer processing called PHY (PHYsical layer) to processing related to optical transmission / reception. In addition to these, the hardware of the device-dependent unit 110 may include a general-purpose server, a layer 2 switch, or the like, and conversely, the hardware (MAC) may not be included, or part of the hardware (PHY). May not be included. For example, the hardware of the device-dependent unit 110 may include only light-related functions without including low-level signal processing such as modulation / demodulation signal processing, forward error correction, codec decoding processing, and encryption processing. It is not necessary to include only a part for encoding data called PCS (Physical Coding Sublayer), and it is not necessary to include PMA (Physical Medium Attachment) for serializing data in addition to PCS. Furthermore, PMD (Physical Medium Dependent) connected to a physical medium may not be included. If the hardware of the device dependent unit 110 can be directly driven / controlled / operated / managed from the middleware 120 without using the software 113 of the device dependent unit 110, the software 113 of the device dependent unit 110 may be omitted.

  The device-independent application 130 includes, for example, a management / control agent 133 that receives communication from the EMS 140 such as an NE controller via the middleware 120, a basic function 132, an extended function (for example, an extended function A131-1, an extended function B131- 2, extended function C131-3). The basic function 132 is a function common to a plurality of communication devices. The extended function is a function given to add a function not included in the basic function to each communication device. However, the device-independent application 130 may not include all of these, or may include more. For example, when the extended function is unnecessary, the extended function is not necessary. The number of extended functions may be other than three. Further, it is preferable that the extended function can be added, deleted, replaced, or changed independently without causing unnecessary influence on other functions. For example, when the extended function is required when the extended function is necessary, for example, when the extended function is required, it may be added, deleted, replaced, or changed according to the service requirements. Good.

  The basic function 132 may be included as a part of the extended function, or may be replaced by the middleware 120 subordinate. When the extended function includes the basic function 132, when the middleware 120 subordinate replaces the basic function 132, or a combination thereof, the device-independent application 130 may not include the basic function 132. When the automatic setting is performed according to the pre-set without receiving the communication from the EMS 140, the management / control agent 133 does not need to input / output the EMS 140 via the middleware 120. Furthermore, when the management / control agent 133 is not provided with the management / control agent 133 and the other device-independent application 130, the basic function 132, or the device-dependent unit 110 is provided, the management / control agent 133 may not be provided. Conversely, input / output may be performed with each device-independent application 130 via the EMS 140 and the middleware 120.

  The device-independent application 130 inputs and outputs with the device-dependent unit 110 via the middleware 120. The device-independent application 130 inputs and outputs to / from each other via the middleware 120 as necessary. In particular, the device-independent application 130 inputs / outputs from / to the management / control agent 133 that inputs / outputs from / to the EMS 140 when performing control / management according to the input / output from the EMS 140.

Input / output between the device-independent application 130 and the device-dependent unit 110 includes, for example, a DBA (Dynamic Bandwidth Assignment) application and protection application for the TC layer Embedded OAM Engine, and a DWBA application and ONU registration authentication application for the TC layer PLOAM Engine. The power saving application inputs and outputs information to and from the OMCI (ONU management and control interface) and L2 function, the MLD (Multicast Listener Discover) proxy application and the L2 function, and the low-speed monitoring application (OMCI) exchanges information with the OMCI. The OMCI and L2 functions operate XGEM (XGPON Encapsulation Method) Framer and encryption.
Here, although DWBA and DBA are separated, they may be integrated or a combination of DBA and DWA.

  For example, the management / control agent 133 is a maintenance operation function application, and inputs / outputs information to / from the EMS 140 in the NE management / control unit via the middleware 120.

  Note that the device-independent application 130 may have a priority order. For example, the management / control agent 133 is the first priority with the highest priority. Below the second priority order is, for example, the order of DBA application, DWBA application, power saving application, ONU registration authentication application, MLD proxy application, protection application, and low speed monitoring application (OMCI).

  The device-independent application 130 is a device vendor, a method, a device type, a device generation, such as ITU-TG. TWDM-PON (Time and Wavelength Division Multiplexing-Passive Optical Network) and ITU-T G. XG-PON and ITU-T G. G-PON and ITU-T G. compliant with the 984 series. It is an application that operates regardless of at least one of the differences between BPON conforming to the 983 series, 10GE-PON conforming to IEEE802.3av, IEEE1904.1, etc. and GE-PON conforming to IEEE802.3ah, etc. As an extended function application, an application for driving a function provided for some vendors, methods, types, and generations via a device-independent API 21 and only for devices of some vendors, methods, types, and generations are provided. It may include apps that drive functions.

  The management / control agent 133 inputs and outputs with the middleware 120. The middleware 120 inputs and outputs NE management / control information with the NE management / control unit. The NE management / control unit may directly exchange NE management / control information with the EMS 140 without using the middleware 120, or may exchange information with the management / control agent 133 through the middleware 120. The middleware 120 inputs / outputs via the device independent application 130 and the device independent API 21, and inputs / outputs via the OAM, driver, firmware, hardware and device dependent API 23 of the device dependent unit 110.

  The middleware 120 outputs the input as it is or in a predetermined format. For example, if the output destination is the device-independent application 130, the middleware 120 sets the format of the device-independent API 21 in a format to be input to each. If the output destination is the OAM, driver, firmware, or hardware of the device-dependent unit 110, the middleware 120 converts to the format of the device-dependent API 23 of the format to be input to each, or terminates and performs predetermined processing. input. It is desirable that the middleware 120 deletes unnecessary input information at each input destination at the time of input, and collects and supplements via the other device-independent API 21 or device-dependent API 23 if there is insufficient information. . In addition, at the time of input to the middleware 120, it may be broadcast or multicast and broadcast to related applications.

  In the figure, the middleware 120 and the device-dependent unit 110 are illustrated as a single unit, but may be configured from a plurality of units. When the hardware of the device dependence unit 110 includes a plurality of processors, the middleware 120 may input / output using inter-processor communication or the like across the processors and hardware. The device-independent applications 130 and the device-independent applications 130 may be arranged in a user space on a single processor as an execution program such as DLL (Dynamic Link Library), or users on two or more processors You may arrange | position on space. The device-independent application 130 may be arranged in the kernel space after securing its input / output IF, or may be arranged together with the middleware 120 having an IF that can be replaced independently with firmware, etc. It is also possible to compile the program again. User space or kernel space may be arbitrarily combined for each device-independent application 130. The device independent application 130 corresponding to the same function may be implemented in both the user space and the kernel space. In this case, for example, either one of them may be selected by switching, the both may be processed together, or the actual processing may be performed by only one of them. The same applies to the software 113 of the device dependent unit 110.

  Desirably, as high-speed processing is required as in main signal processing, DBA processing, and low-layer signal processing, there is a trade-off between scalability and immediacy of replacement, but high-speed processing is expected with less overhead. It is desirable to incorporate in kernel space and firmware. The processor where the device-dependent application is arranged is also the user space or kernel of the processor that performs the actual processing or the processor in the vicinity from the viewpoint of the influence on the other programs due to the restriction of the bus and speed due to the communication between the processors and the occupation of the communication path It is desirable to place it on space or firmware. However, in order to reduce the ability of a processor that performs actual processing or a processor in the vicinity thereof, the communication cost due to communication between processors increases, but processing may be performed by a remote processor.

  The device-independent API 21 is preferably provided in the middleware 120 in advance, assuming an extended function to be added later. However, if necessary, the device-independent API 21 is configured to suppress modification of the device-dependent API 23 and other device-independent applications 130. You may add and delete.

  1 is described on the premise of an OLT (Optical Line Terminal) of a PON compliant with the ITU-T recommendation such as TWDM-PON, but it may be an ONU or an ITU other than the TWDM-PON. -It may be either OLT or ONU of PON compliant with T recommendation, or may be PON compliant with IEEE standards such as GE-PON, 10GE-PON, etc. The TC layer and PMD layer are in the corresponding layer. It will be the same if it is read.

(Embodiment 1-1)
TWDM-PON mainly has 8 functions of PON multicast function, power saving control function, frequency / time synchronization function, protection function, maintenance operation function, L2 type signal processing function, PON access control function, and PON main signal processing function. Take the case of having an example.

  FIG. 7 shows an example of a signal / information flow between eight main functions. The PON main signal processing function may be connected to PMD (outside the main 8 functions), PON access control function, maintenance operation function (PLOAM processing, OMCI processing) and L2 main signal processing function, PON multicast function, power saving control The function, the frequency / time synchronization function, and the protection function may be connected to the group consisting of the maintenance operation function, the L2 main signal processing function, the PON access control function, and the PMD, respectively. Each function will be described with reference to FIGS.

  FIG. 8 is a diagram of the PON main signal processing function. As processing that constitutes the PON main signal processing function, PHY adaptation, framing, and service adaptation may be provided in the upstream signal processing order (downstream signal processing is reverse). These processes may include basic block generation / extraction, scrambling / descrambling, FEC decoding / encoding, frame generation / separation, GEM encapsulation, fragment processing, and encryption. The PHY adaptation may include synchronization block extraction, descrambling, and FEC decoding in the order of upstream signal processing, and FEC encoding, scrambling, and synchronization block generation in the order of downstream signal processing. Equivalent processing may be realized by a combination of basic processing without providing PHY adaptation, framing, and service adaptation processing. Further, the order may be changed. For example, FEC processing may be provided in addition to PHY adaptation.

  In this main function, when processing of 10 Gbit / s / λ and 2.5 Gbit / s / λ is processed for each wavelength, stream processing of 10 Gbit / s / λ and 2.5 Gbit / s / λ or more, respectively, If multiple wavelengths are processed, multiple wavelengths are required.

  FIG. 9 is a diagram of the PON access control function. The processing to be configured includes ONU registration authentication, DBA, and λ setting switching (DWA). These processes may be composed of basic processes. For example, ONU registration authentication is ranging that configures initial processing, authentication deletion registration, start / stop, DBA receives bandwidth request, traffic measurement, history retention, allocation calculation, allocation processing, setting switching calculation, setting switching processing, setting switching status grasp All or some of them, λ setting switching is composed of all or some of bandwidth request reception, traffic measurement, history retention, allocation calculation, allocation processing, setting switching calculation, setting switching processing, and setting switching status grasp. Also good. Equivalent processing may be realized by a combination of basic processing without providing ONU registration authentication, DBA, and λ setting switching (DWA). Further, the order may be changed. In this main function, ONU fast start-up, BWMap within the DBA cycle, non-instantaneous λ setting switching, and the like are required as necessary.

  As an example of function sharing, as the registration / authentication, the time-dependent ranging process may be the device-dependent unit 110, and the subsequent authentication and key exchange may be the application. In DBA / λ setting switching, a simple repetitive process may be used as the device-dependent unit 110 and reflection in the ideal state may be used as the application.

  FIG. 10 is a diagram of the L2 main signal processing function. The processes to be configured include MAC learning, VLAN control, path control, bandwidth control, priority control, delay control, and Copy. These processes may include basic processes such as address management, Classifier, Modifier, Policyr / Shaper, Cross Connect, Queue, Scheduler, Copy, and traffic monitor. MAC learning, VLAN control, path control, bandwidth control, priority control, delay control, and copy may not be provided, and equivalent processing may be realized by a combination of basic processing. Further, the order may be changed.

  In this main function, when processing of 10 Gbit / s / λ and 2.5 Gbit / s / λ is processed for each wavelength, stream processing of 10 Gbit / s / λ and 2.5 Gbit / s / λ or more, respectively, If multiple wavelengths are processed, multiple wavelengths are required. FIG. 11 is a diagram of the maintenance operation function (1) device setting / management. The processing to be configured includes ONU / OSU / OLT / SW device settings (manual, batch, automatic, operation trigger), setting backup, FW update, device control (reset), and redundant configuration support. These processes may be composed of CLI-IF, operation IF, general-purpose Config-IF (such as NETCONF / OPENFLOW / SNMP / CLI), which are basic processes, and table management. Equivalent processing may be realized by a combination of basic processing without providing device setting, setting backup, FW update, device control, and redundant configuration support. Further, the order may be changed.

  In this main function, within 100 ms from receiving the instruction until ACK transmission, and within 200 ms from receiving the instruction until transmission completion notification transmission (however, the setting backup including data transfer and FW update depend on the scale (size and number of users) To comply with regulations such as As an example of the function sharing, it is possible to use an application except for a hardware Config, and to use an application on the 16 external server in FIG. 2 without having software and setting data in the ONU or OLT. It can also be realized by unifying commands and defining sequences.

  FIG. 12 is a diagram of the maintenance operation function (2) low-speed monitoring / testing. The processing to be configured includes device status monitoring (CPU / memory / power supply / switching), traffic monitoring, alarm monitoring (ONU abnormality, OLT abnormality), and test (loopback). These processes may comprise basic processes of alarm notification, log recording, L3 packet generation / processing, and table management. Device status monitoring, traffic monitoring, alarm monitoring, and testing may be realized by combining the same processing with basic processing. Further, the order may be changed.

  In this main function, it is required to comply with regulations such as latency within 100 ms. As an example of function sharing, only the notification / display IF is an application, and items that need to be monitored (CPU load, memory usage, power supply state, power consumption, Ethernet link state, etc.) are the device-dependent unit 110 and are device-dependent. An application that cuts off the IF, such as reading notification from the unit 110, sending NW (network) notification, and writing to a file, can also be used.

  FIG. 13 is a diagram of the maintenance operation function (3) high-speed monitoring / control. The processing to be configured includes high-speed monitoring / control exchanges (sleep instruction / response, λ setting switching instruction / response, etc.). As means for this processing, a Physical Layer OAM (PLOAM) message and a bit display (Embedded OAM) in the header are used. These processes may be composed of basic processes such as PLOAM processing, Embedded OAM processing, communication with a power saving function unit, communication with a protection function unit, and communication with a PON access control unit. The monitoring / control exchange requiring high speed may be realized by combining the same processing with the basic processing. Further, the order may be changed. This main function is required to comply with regulations such as PLOAM processing within 750 microseconds.

  FIG. 14 is a diagram of the PON multicast function. The processing to be configured includes multicast stream identification / sorting, MLD proxy / snooping, ONU filter setting, and transition between wavelength settings. These processes may include basic processes such as L2 identification / distribution, L3 packet processing (preferably provided with IPv6Parse), L3 packet generation, table management, and communication with the OMCI function. Multicast stream identification / distribution, MLD proxy / snooping, ONU filter setting, and inter-wavelength setting transition may be realized by a combination of basic processes. Further, the order may be changed. In this main function, when 10Gbit / s / λ and 2.5Gbit / s / λ processing is performed for each wavelength, the identification / distribution is 10Gbit / s / λ and 2.5Gbit / s / λ or more, respectively. If the stream processing is to process a plurality of wavelengths, a plurality of wavelengths are required to comply with regulations such as zapping performance (JOIN latency) within 1.5 seconds on average as packet processing. As an example of the function sharing, the identification and distribution of the multicast (MC) stream can be processed by software if it is a CPU or the like having a high-speed processing capability, but hardware + config is desirable. In addition, the application system and ONU setting for uplink are assumed to be applications because the frequency and delay restrictions are loose.

  FIG. 15 is a diagram of the power saving control function. The processing to be configured includes a sleep proxy / traffic monitor, ONU wavelength setting, and transition between wavelength settings. These processes may include basic processes such as L3 packet processing (preferably with IPv6Parse), L3 packet generation, table management, OSU power saving SD (State Diagram), and communication with the OMCI function. The sleep proxy / traffic monitor, ONU wavelength setting, and inter-wavelength setting transition may be realized by a combination of basic processes. Further, the order may be changed. This main function is required to comply with regulations such as transmission / reception rise time (receiver / transmitter) of 10 ms / 5 ms, rise time (LC / OSU / OLT) of 100 ms / 1 s / 10 s, and the like. As an example of function sharing, a PS (Power Save) application, or depending on a signal, proxy processing can be used as an application. The power saving control state transition management (driver unit) requires speed, but can be an application. The traffic monitor can be a config only application.

  FIG. 16 is a diagram of the frequency / time synchronization function. The OLT synchronizes its real-time clock (RTC) with, for example, a higher-level device by SyncE (Synchronous Ethernet) (for frequency synchronization) and IEEE 1588v2 (time synchronization). Furthermore, the correspondence between the PON super frame counter (SFC) and absolute time (ToD: Time of Day) information is notified to the ONU using OMCI. These processes may be configured by holding a real-time clock, which is a basic process. Equivalent processing may be realized by a combination of basic processing. Further, the order may be changed.

  In this main function, frequency synchronization accuracy +/− 50 ppb (LTE FDD, TDD), time synchronization accuracy +/− 1 to 1.5 us (LTE TDD, small cell), +/− 1 us (G.987.3) It is required to comply with such regulations. As an example of the function sharing, the real-time clock itself is the device-dependent unit 110. For example, the time adjustment calculation to the higher-level device may be an application (the device-dependent unit 110 may be used depending on accuracy).

  FIG. 17 is a diagram of the protection function. As processing to be configured, redundancy switching (CT, SW, NNI, CONT, PON (Type A, B, C)) is provided. These processes may be configured by basic processes such as redundant path setting, switching trigger detection, switching notification transmission / reception, switching processing, and the like. Equivalent processing may be realized by a combination of basic processing. Further, the order may be changed. In this main function, forced switching is required to comply with regulations such as 50 ms or less. As an example of function sharing, an application can be used except for hardware switching trigger detection and switching processing such as failure detection. When an instruction to (from) the EMS 140 is detected when a switching trigger is detected without setting a redundant path in advance, it is device-dependent.

  The main 8 functions may be provided as necessary. For example, only the PON main signal processing function, the PON access control function, the L2 main signal processing function, the maintenance operation function may be provided, or other functions may be provided. May be.

  FIG. 18 shows an example of whether or not the main 8 functions can be softwareized. FIG. 18 is an example of a function group and whether or not software is possible. An example of whether or not to enable software for each of the 8 functions in the function group is given below.

  Specifically, the PON main signal processing function of the first function group includes functions such as PHY adaptation, framing, and service adaptation, and is difficult to be softwareized.

  The PON access control function of the second function group includes ONU registration authentication control, ONU registration authentication application, DBA control, DBA application, DWA control (λ setting switching), and DWA application (wavelength protection and wavelength sleep). The ONU registration authentication control application, the DBA control application, and the DWA application (including wavelength protection and wavelength sleep) can be softwareized. Further, as an effect (differentiation factor) of extensibility of each function, the ONU registration authentication application has an authentication scheme concealment, the DBA application has a flexible QoS, and includes a DWA application (wavelength protection and wavelength sleep). ) Has a flexible QoS and is preferably softwareized.

  The L2 main signal processing function of the third function group includes functions such as MAC learning, VLAN control, path control, bandwidth control, priority control, delay control, and copy, and is difficult to be softwareized.

  The maintenance function of the fourth function group includes device setting / management, setting / management application, low speed monitoring / testing, low speed monitoring application (ONU / OLT monitoring: EMS), low speed monitoring application (OMCI), It consists of functions such as high-speed monitoring / control and high-speed monitoring apps. Settings / management apps, low-speed monitoring (OMCI) apps, and high-speed monitoring apps can be softwareized. Low-speed monitoring apps (ONU / OLT monitoring) depend on the situation. . Also, as an effect (differentiation factor) of the extensibility of each function, the setting / management application has the effect of drastically reducing Opex by cooperating with the controller, and the low-speed monitoring application (ONU / OLT monitoring: EMS) By cooperating with EMS140, it has the effect of drastically reducing Opex.

  The multicast (frame processing) of the fifth function group includes MLD proxy and multicast (frame processing) functions, and the MLD proxy application can be softwareized.

  The power saving control function (access control) of the sixth function group includes functions of power saving control and a power saving application, and the power saving application can be softwareized. Further, as an effect (differentiation factor) of extensibility of each function, the power saving application has a flexible QoS effect.

  The frequency / time synchronization function of the seventh function group includes a frequency / time synchronization function and is difficult to be softwareized. The protection function of the eighth function group includes functions of protection control and a protection algorithm (application), and the protection algorithm (application) can be softwareized. Further, the protection algorithm has the effect (differentiation factor) of the extensibility of each function.

  The evaluation of whether or not each function in FIG. 18 can be softwareized is an example on the assumption that the processing capability of the OLT assumed in 2018 and the application of the soft switch are not assumed. It may be changed as appropriate assuming an assumed processing capacity and application of a soft switch. Further, the internal configuration of each function may be another configuration as long as the same function can be realized.

  As shown in FIG. 18, an algorithm included in the main 8 functions is set as a main software area. The function as the software area is assumed to be a device-independent application 130 on the device-independent API 21. For example, algorithms in the ONU registration authentication function, DWBA function, setting / management / monitoring control function, and power saving control function that contribute to the differentiation service are treated as extended functions in the device-independent application 130. The MLD proxy application includes a multicast function.

  The extended function is an extended function depending on the importance of the update frequency of the function and the realization of the original specification. It is preferable to use middleware 120 other than the basic function 132 or the device-independent application 130, device-dependent software, or hardware that has a low update frequency or a low requirement for implementation such as a unique specification. In particular, it is preferable to leave the functions that are limited by the processing capability of the software as hardware. For example, functions that contribute to service differentiation or high frequency of renewal such as DBA to improve main signal priority processing and line utilization efficiency, and management that is closely related to the operational flow of the operator and requires unique specifications for each operator From control functions to extended functions.

  An example of an architecture based on FIG. 18 is shown in FIG. In the optical access system according to FIG. Complies with 989 series. The connection relationship shown below is an example, and the connection interposed therebetween may be a connection that does not intervene, or may be connected to only a part of a plurality of connection relationships, or may be other connections. . The same applies to other explanations. In the EMS functioning as the NE controller, a low-speed monitoring application (EMS-IF) and a setting / management application are arranged via an IF conversion application via middleware. The IF conversion application corresponds to an SBI application that converts an SBI (South Band Interface) command that is a control IF for a network entity such as OLT from an EMS such as an NE controller. If the IF conversion application performs IF conversion, but the low-speed monitoring application (EMS-IF) and the setting / management application have an API that performs IF conversion or does not need to perform IF conversion, the IF conversion application is It is not necessary to prepare. The low-speed monitoring application (EMS-IF) and the setting / management application connected to the L2 (layer 2) function are connected to NE control / management that performs EMS, NE management, and the like via middleware. The low speed monitoring application (OMCI), the MLD proxy application (multicast application), and the power saving application are each connected to the L2 function via middleware.

The protection application is connected to the PLOAM Engine and Embedded OAM Engine via middleware. The power saving application is connected to the OMCI and the PLOAM Engine via middleware. The ONU registration authentication application and DWBA application are connected to the PLOAM Engine via middleware, and the DBA application is connected to the Embedded OAM Engine via middleware. The power saving application may be operated between the protection application, the ONU registration authentication application, the DWBA application, and the DBA application via the middleware. Input from other devices is connected to the DBA application via middleware. These connections are examples, and an input from another device may be connected to an application other than the DBA application, such as a protection application or a DWBA application. Further, an input from another device may be IF-converted via an IF conversion application via middleware, or may be connected to a DBA application or the like via a setting / management application via middleware.
The functions of the access network device such as the above main eight functions are converted into parts, and a configuration that enables flexible combination thereof is realized.
As a result, new services are provided through co-creation with various business players, and various requests (bandwidth, delay, cost, reliability, etc.) from service providers and end users corresponding to “Middle B” of B2B2C. , Etc.) can be flexibly and quickly dealt with.
Such an access system architecture that enables rapid provision of devices of various telecommunications carrier requirements and various applications may be configured as FASA (Flexible Access System Architecture). Different functions may be converted into software, and the softwareized function may be configured as a FASA application. A generalized input / output interface for mounting a FASA application may be configured as a FASA application API (Application Programming Interface). In other words, the apparatus is configured as follows.
1. Instead of developing as a dedicated device specialized for functions and services as in the past, the functions constituting the access network device are made into parts.
2. The functions that differ for each service and each telecommunications carrier are realized by software components that have generalized input / output interfaces.
3. By increasing the independence between software components, software functions can be operated on a replaceable platform, so that necessary functions can be flexibly and economically realized according to service requirements while maintaining service quality.
In order to realize the above configuration, functions that differ for each service or carrier are realized by software components (FASA applications) that have generalized I / O interfaces, and on a platform (FASA platform) that can replace them. Make it work.
A conceptual diagram is shown in FIG. As shown in the figure, an access network device based on FASA is composed of a FASA application and a FASA infrastructure. The “FASA application” realizes functions different for each service or each communication carrier with software components having a generalized input / output interface (FASA application API), which can be replaced. By adding or replacing depending on the service, services of various requirements can be provided quickly and easily.
“FASA Platform” is a basic component of an access device that provides a FASA application API to a FASA application and provides functions that do not need to be changed according to services or requests due to standardization. is there. In the FASA base, each function constituting the FASA base is realized by hardware or software in accordance with requirements such as processing performance. Specifically, the configuration 1 and the configuration 2 shown in the configuration example of componentization by FASA in FIG. 30 may be used.
Configuration 1 is a software component of a function (FASA application) that needs to be replaced in order to respond to a different request for each service or each carrier. In other words, the upper part of the FASA application API (FASA application) is the subject of consideration for software componentization, and the configuration of the FASA base is not subject to consideration. For example, in the case of the NG-PON2 system of this configuration, the NG-PON2 protocol standardized on the FASA basis is provided, and changes to other PON protocols such as EPON are not considered.
Configuration 2 is a configuration that realizes an access network device using more general-purpose hardware by making functions other than the FASA application (FASA-based) functions into software components.
The FASA application API is the same in both configurations 1 and 2. FIG. 31 shows an example in which the FASA base is divided into general-purpose hardware and external hardware components. The access network apparatus shown in the figure includes three component categories, “(1) FASA application”, “(2) general-purpose hardware”, and “(3) external hardware component”. By combining these, necessary functions can be provided quickly and easily. “(2) General-purpose hardware” is not limited to an access network device, but includes a general-purpose communication function as a common component. By making common parts using general-purpose hardware, it is possible to reduce the frequency of newly developing a device from the member level according to service requirements. In addition, by using common parts, it can be expected that the maintenance cost will be simplified by reducing the apparatus cost and the number of maintenance items. “(2) General-purpose hardware” is hardware that is not a dedicated device for an access system, such as a general-purpose server or a white box switch, for example, firmware necessary for the hardware, software such as an OS, “(1) The FASA application API middleware for "FASA application" is installed. “(3) External hardware component” is a function of an optical transmitter / receiver that is difficult to implement on “(1) FASA application” or “(2) General-purpose hardware”. "Wear" and implemented separately. “(3) External hardware component” is hardware other than “(2) General-purpose hardware” such as an optical transceiver. When a media converter is realized by using a simple optical module as “(3) external hardware component”, software such as OS installed in “(2) general-purpose hardware”, “(1) The operation is performed using the FASA application API middleware for the “FASA application”. On the other hand, when a PON MAC chip is mounted on “(3) External hardware”, firmware necessary for the operation of the hardware, software such as OS, and FASA application API for “(1) FASA application” Middleware may be installed directly. In any case, according to the service requirements, for example, external hardware parts having different transmission capacities and transmission methods are replaced, and software parts corresponding to the FASA base are replaced correspondingly, that is, the software parts constituting the FASA base are replaced. Thus, it is possible to realize an access network having an optimum transmission capacity and transmission method according to the situation while using the same general-purpose hardware.
In the present application, each term has the following meaning.
FASA application API (FASA application API): An API that connects a FASA application and middleware for the FASA application API.
FASA application (FASA application): A replaceable software component implemented using the FASA application API.
FASA platform: A basic component of an access device that provides a FASA application API that can implement a FASA application, and provides functions that do not need to be changed according to services or requests due to standardization. It is. FASA base = device-dependent unit + (for FASA application API) Middleware = device-dependent unit + basic function software component: Software in which necessary functions can be exchanged.
FASA application API middleware: Software that provides the FASA application API for the FASA application in the FASA infrastructure. The FASA application API middleware provides means for communication between FASA applications and with other FASA-based functions, and absorbs differences such as lower layers than the FASA application.
External hardware components: Functions that are difficult to implement on general-purpose hardware, separated from general-purpose hardware.
General-purpose hardware: Hardware that can be used universally, not just for access network services, such as general-purpose servers and white box switches.
The main functions of the access system and the target of FASA application are shown in FIG.
First, main functions of the access system will be described.
The PON main signal processing function is a function group that processes main signals transmitted to and received from the ONU, and includes generation and separation of PON frames, forward error correction (FEC), and the like.
The PON access control function is a control function group for performing the above-described main signal transmission / reception, and includes dynamic bandwidth allocation, ONU registration authentication, and the like.
The L2 main signal processing function is a function group that transfers and processes main signals between the PON side port and the SNI side port, and includes functions such as MAC address learning, VLAN control, priority control, and traffic monitoring.
The maintenance operation function is a group of functions for smoothly maintaining and operating a service by an access device. A function for performing device settings for ONUs and OLTs (OSUs and switches), software update, device and service management, various types It includes a function for monitoring whether the function is operating normally, a function for actively issuing an alarm when an abnormality occurs, a test function for investigating the range and cause when the abnormality occurs, and the like. In addition, the maintenance operation function is connected to a maintenance operation system that manages a large number of access devices, thereby realizing smooth maintenance operation from a remote location.
The PON multicast function is a function group that forwards a multicast stream received from the SNI side to an appropriate user, and includes a function of identifying and allocating the multicast stream and performing ONU filter setting.
The power saving control function is a group of functions for reducing the power consumption of ONUs and OLTs. In addition to the power saving function specified in the standardization, the influence on the service is minimized by linking with the traffic monitor. While including the function to get the maximum effect.
The frequency / time synchronization function is a function group for providing accurate frequency synchronization and time synchronization to the devices under the ONU. The frequency / time synchronization function is a function to subordinately synchronize its own real-time clock to the host device, or to the ONU using a PON frame. Includes a function to notify time information.
The protection function is a function group for continuing the service by switching or taking over from the active system to the standby system when a failure is detected in a configuration where redundancy is provided by a plurality of hardware such as between switches and OSUs. And functions such as detection of a switching trigger and execution of switching processing. In addition, the protection function provides a function to keep the service operating in a reduced operation without stopping the entire service when a failure is detected or manually switched.
Next, the concept and example of whether each function is implemented as a FASA application or on a FASA platform will be described.
Among the functions shown in FIG. 32, functions that need to be changed depending on the service and functions that should be extended to satisfy the requirements unique to the telecommunications carrier are realized as FASA applications. On the other hand, functions defined by standardization and the like that have little room for expansion are mounted on the FASA base.
FIG. 32 shows that, for example, the PON main signal processing function is realized as a FASA base. ITU-T G. To realize a 40 Gbit / s class access device compliant with the 989 series, basic PON main signal processing functions such as frame format, frame encryption, and forward error correction (FEC) function must be implemented according to the standard. is there. Since these basic functions are common regardless of services, they are implemented on the FASA infrastructure.
As another example, FIG. 32 shows that “responding to a service request” of the DBA function included in the PON access control function is realized as a FASA application. For example, there are cases where low latency is provided depending on the provided services and cases where bands are efficiently allocated to a large number of users. In order to satisfy different requirements for each service, it is desirable to separate the bandwidth allocation procedure and policy as a FASA application from standard processing (conversion to the BWmap format, etc. defined in the standard).
Even if the target of the service to be provided is for the same mass, it is conceivable that the fairness policy is different, for example, the response policy for heavy users differs depending on the communication carrier. Specifically, for example, a telecommunications carrier that requires fair control with a small granularity, such as a PON unit, performs fair control even within the DBA application, and a telecommunications carrier that performs fair control only with a large granularity, such as an access device unit, has a concentrating function. It is assumed that each QoS specification is satisfied by using.
As described above, in FASA, different requests are realized by replacing the FASA application. Therefore, a means for replacing the FASA application is required, but what is adopted as the replacing means varies depending on the communication carrier and the operation. For example, when an existing maintenance operation system used by a telecommunications carrier uses TFTP (Trivial File Transfer Protocol) for software update, it is equipped with TFTP and updated from outside the maintenance operation system using SFTP (SSH FTP). In some cases, SFTP is provided. In the future, it is assumed that discussions on standardization regarding the interface between the device and the controller will progress, and it is necessary to consider additions and changes to the interface following the progress of standardization. For this reason, other systems to which the access device is connected and functions that require customization in accordance with the operation thereof may be realized as FASA applications.
In addition, in FASA, not only protection performed by fully duplicating the entire FASA infrastructure but also protection performed only by a part of the FASA infrastructure is assumed. For example, when the FASA base is equipped with an optical switch and supports PON protection, when a single PON is equipped with multiple wavelengths and supports wavelength protection, when only a switch is duplicated, or when these are combined, etc. Multiple redundant configurations are possible. By implementing the protection function as a FASA application, it is possible to cope with the expected redundant configuration, and it is possible to easily cope with various redundant configurations by reusing the corresponding part.
Further, a function to be converted into a FASA application, that is, an extended function, may be an extended function according to the importance of realizing the update frequency of the function, unique specifications, etc., among the functions that can be converted to software. It is preferable to use the middleware 120 for the FASA application API other than the basic function 132 and the device-independent application 130, the device-dependent software, and the hardware that have a low update frequency or a low requirement for realizing an original specification or the like. In particular, it is preferable to leave the functions that are limited by the processing capability of the software as hardware. For example, functions that contribute to service differentiation or high frequency of renewal such as DBA to improve main signal priority processing and line utilization efficiency, and management that is closely related to the operational flow of the operator and requires unique specifications for each operator From control functions to extended functions.
An example of an architecture based on FIG. 32 is shown in FIG. The optical access system according to FIG. It is an example of OLT based on 989 series. In the figure, the controller and the external device are not included in the OLT, but are described to illustrate communication with the FASA application API. The logical model includes a FASA application and a FASA base that provides the FASA application with a FASA application API. The FASA infrastructure includes middleware for FASA applications.
The FASA application API middleware absorbs differences in hardware and software vendors and methods that make up the FASA infrastructure. A FASA application API set that does not depend on a vendor or a system is defined on the middleware for the FASA application API, and necessary functions are realized for each service or each communication carrier by replacing the FASA application (application). Communication between FASA applications and setting management by a controller or the like are performed via the FASA application API middleware. Note that FASA application API middleware may not be used.
The FASA application API set is a common API group used in the FASA application, and an API required for each FASA application is selected from the API set and used.
The connection relationships shown above and below are examples, and the connection interposed between them may be a connection that does not intervene, or only a part of a plurality of connection relationships may be connected. Also good. The same applies to other explanations. The EMS functioning as the NE controller is an OLT setting management system such as NE-OpS, and the control signal from the EMS communicates with the SBI application via the FASA application API provided by the middleware. The control signal that communicates with the SBI application is terminated by the control management application (for example, the low-speed monitoring application (EMS-IF) and / or the setting management application) via the FASA application API. The IF conversion application corresponds to an SBI application that converts an SBI (South Band Interface) command that is a control IF for a network entity such as OLT from an EMS such as an NE controller. If the IF conversion application performs IF conversion, but the low-speed monitoring application (EMS-IF) and the setting / management application have an API that performs IF conversion or does not need to perform IF conversion, the IF conversion application is It is not necessary to prepare. The low-speed monitoring application (EMS-IF) and the setting / management application connected to the L2 (layer 2) function are connected to NE control / management that performs EMS, NE management, and the like via middleware. The low-speed monitoring application (OMCI), the MLD proxy application (multicast application), and the power saving application are each connected to the L2 function via the FASA application API middleware.
The protection application is connected to the PLOAM Engine and the Embedded OAM Engine via the FASA application API middleware. The power saving application is connected to the OMCI and the PLOAM Engine via the FASA application API middleware. The ONU registration authentication application and the DWBA application are connected to the PLOAM Engine via the FASA application API middleware, and the DBA application is connected to the Embedded OAM Engine via the FASA application API middleware. The power saving application may be operated between the protection application, the ONU registration authentication application, the DWBA application, and the DBA application via the FASA application API middleware. The input from the external device is connected to the DBA application via the FASA application API middleware. These connections are examples, and an input from an external device may be connected to an application other than the DBA application, such as a protection application or a DWBA application.
The external device is, for example, a BBU of a mobile system or another OLT, and is a device that communicates with the FASA application via the FASA application API. In the figure, an external device (such as BBU) is communicating with the DBA application. Even if the input from the external device is IF converted via the IF conversion application via the FASA application API middleware, or connected to the DBA application via the setting / management application via the FASA application API middleware. Good.
In the figure, communication between a setting management application and other applications among communication with a lower layer than the FASA application API middleware, communication between applications, and communication between applications is indicated by different arrows.

  FIG. 20 shows an example of capability deployment on the apparatus. In the optical access system according to FIG. 20, an example is shown in which functions are distributed and arranged on a plurality of CPUs on a CPU version. In this example, the CPU version of the CPU is divided into three groups: CONT (controller version, controller, control unit, etc.), OSU, and SW. Each of the three groups of CPUs may be a single CPU or may be composed of a plurality of CPUs, a GPU (Graphics Processing Unit), an FPGA (Field Programmable Gate Array), or a DSP (Digigal Signal Processor). And an arithmetic function such as ASIC (Application Specific Integrated Circuit) or the like.

  The plurality of CPUs on the CPU version may be a single CPU. With a single CPU, overhead processing for inter-CPU communication is reduced. Further, instead of the centralized processing in the CPU version, each group may be distributed and arranged in three PKGs (package, version) (Cont version, OSU, SW). As shown in FIG. 20, the CONT version connected to the device setting IF and the EMS-IF performs input / output of data through each application group divided into three groups of CONT direction, OSU direction, and SW direction. Each application in the direction was a low speed monitoring application (OMCI), a low speed monitoring application (EMS-IF), and a setting management application. In addition, each application for SW is an MLD proxy application. Each application for OSU is a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWA application, and an ONU registration authentication application. These functions and groups of functions are examples, and may be rearranged, or deleted / added abstracted.

  Middleware is installed in each OSU and switch. The middleware may be centrally installed in any one of them as long as the functions and the connectivity between the hardware can be secured. Each OSU includes an optical transceiver (λCard in the figure) having a predetermined wavelength. A control version (CONT. In the figure), which is a control unit in the OLT, controls each application and hardware suitable for CONT. The CONT-oriented, OSU-oriented, and SW-oriented applications are connected to input / output data to / from each other via middleware or without middleware.

  Each application is an example of processing by a CPU on a CPU package. In the figure, each application is processed for the control version (CONT. In the figure) that is a control unit in the OLT, the process for the OSU package (OSU in the figure) provided with the optical transceiver (λCard in the figure), the OSU and the upper side. It is classified into three groups suitable for SW packages that exchange data with these devices. Power saving app, protection app, high speed monitoring app, DBA app, DWA app, ONU registration authentication app as OSU group, MLD proxy app as SW group, low speed monitoring app (OMCI), low speed monitoring app (EMS- as CONT group) IF), a setting management application. Furthermore, although the centralized arrangement in the CPU version is assumed, the classified applications of each group may be distributed and arranged in each PKG (Cont, OSU, SW).

  Moreover, you may arrange | position on either of Cont, OSU, SW, or those some combination irrespective of said classification | category. Further, the apparatus setting IF in the figure may be a part of the EMS-IF, or may be equivalent to the API 25 in FIG. Further, although the processing of the application is performed on the CPU, part or all of the processing may be performed on an alternative having a processing function, for example, a processor other than the CPU, such as GPU, NPU, DSP, or FPGA. The same applies to the other embodiments of the present application.

  FIG. 21 shows an example in which an application is arranged on a server or the like instead of the CPU package. The application processes on the server or the like, and the processing result is transmitted on the transmission line in a format that can be transmitted on the transmission line such as an Ethernet frame, and then arrives at the OLT. Here, the format that can be transmitted on the transmission path may be a frame other than the Ethernet frame, transmission of TDM, or the like, and via a converter (CONV. In the figure), but the OSU, SW, or λ card converts it. If it is possible to receive the processing result of the application without going through the machine, the converter is unnecessary. The server or the like may be equivalent to the external server 16 in FIG. 2 or may be equivalent to the proxy unit 15.

  FIG. 22 shows an example of processing other than an application and an application. In FIG. 22, descriptions of middleware corresponding to FIGS. 1 and 3 or basic functions corresponding to FIGS. 4 and 5 are omitted. In the figure, an example in which the enclosure of the CPU is processing by the basic function and the unique function, and the processing by the OSUMAC in the vendor-dependent portion is shown, but it is not limited to this classification. The CPU in this figure may be a part having the processing capability on the CPU package in FIG. OSUMAC assumes a dedicated LSI that performs OSU processing, but a general-purpose LSI may be used if equivalent processing is possible.

  In the optical access system according to FIG. 22, the CPU includes, as a first group, Fault Management of the maintenance operation function, GTC / PMD Config of the maintenance operation function, ONU Activation / Deactivation of the PON access processing function, and DBA of the PON access processing function. Λ (wavelength) allocation change of PON access processing function, power saving control function Sleep and protection function as the second group, maintenance operation function Service Management and maintenance operation function as the third group The fourth group includes Fault Management of the maintenance operation function, Performance Management of the maintenance operation function, and MLD proxy of the multicast function.

  SW is an L2 signal processing function VLAN function, an L2 signal processing function QoS function and an L2 signal processing function Multiplex (Mux), an L2 signal processing function Demujltiplex (Dmux), an L2 signal processing function CrossConnect (XC) and L2 A multicast function of a signal processing function, and a copy function (Copy) of an L2 signal processing function. The OSU MAC has Framing of the PON main signal processing function, Security such as encryption / decryption of encryption of the PON main signal processing function, FEC function of the PON main signal processing function, and frequency / time synchronization function. The OSU MAC may perform data processing in the order of XGEM Framer, encryption, XGTC Framer, FEC, PHY Framer, SP conversion, and PMD. The encryption may be performed by the security function of the PON main signal processing function, the FEC may be performed by the PON main signal processing function (FEC), and the framer sync located in the previous stage of the PHY framer may be performed by the frequency / time synchronization function.

  FIG. This corresponds to the 989.3 functional diagram. In FIG. 23, descriptions of middleware corresponding to FIGS. 1 and 3 or basic functions corresponding to FIGS. 4 and 5 are omitted. As shown in FIG. 23, each application uses a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWA application, and an ONU registration authentication application. In TWDM TC Layer, (1) has PHY Burst Timing and Profile Control, (2) has Upstream Bandwidth Management (Mgmt.) DBA Control and FS Frame / Burst function as PLOAM Partition function, Embedded Header Field function and XGEM partition (3) has User Data Adapter, OMCI Adapter, and XGEM Engine.

Of the AMCC PMC and Conventional TWDM PMD that the Layer has, it is connected to the AMCC PMC.

  FIG. 24 shows an example in which, in addition to user data, PLOAM and OMCI also receive corresponding ones from 4 or 5 or 6 in FIG. 2 via SW. As shown in FIG. 24, each application uses a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWA application, and an ONU registration authentication application. In TWDM TC Layer, (1) has PHY burst timing and profile control, (2) has Upstream Bandwidth Management (mgmt.) DBA Control and FS Frame / Burst as PLOAM Partition, Embedded Header Fields and XGEM Partition (3) has User Data Adapter, OMCI Adapter, and XGEM Engine.

The User Data Adapter is connected to TWDM via Security Key Management (mgmt.), ONU Power Management (mgmt.), TWDM Channel Management (mgmt.), TWDM TC Functions with Protection Control, PLOAM Proccessor, and AMCC PHY. Of AMCC PMC and Conventional TWDM PMD possessed by PMD Layer, it is connected to AMCC PMC. Note that the PLOAM Proccessor and AMCC PHY shown in FIG. 24, the FS Frame / Burst PLOAM Partition and PLOAM Proccessor, and the FS Frame / Burst Embedded Header Fields and TWDM TC Functions are connected via SW. .

  In the example of FIGS. 1 and 3, the software areas are the basic function 132, the management / control agent 133, the extended function A 131-1, the extended function B 131-2, the extended function C 131-3, and the middleware 120. Softened areas include service adaptation (encryption, fragment processing, GEM (GPON Encapsulation Method) frame) / XGEM (XGPON Encapsulation Method (framed)) X, PHY adaptation FEC, scramble, synchronous block generation / extraction, GTC ( GPON Transmission Convergence), PHY framing, SP conversion, and encoding method may be targeted.

  An example of implementation of a software function of an architecture and an example of function deployment corresponding to hardware will be described. The function deployment includes, for example, a software function in a network device or an external server.

  Assume an OLT including a plurality of OSUs, switches, an information processing unit, and a control unit. Each OSU includes a transmission / reception unit that is different for each wavelength. In this case, the middleware 120 is installed in each OSU and switch, and a software area such as the device-independent application 130 is installed in the information processing unit.

  The information processing unit, that is, the CPU executes the device-independent application 130. The device-independent application 130 includes an OSU extended function, a switch extended function, and a control unit extended function. The extended functions for OSU are, for example, a power saving application, a protection application, a DBA application, and an ONU registration authentication application. The extended function for the switch is, for example, an MLD proxy application. The extended functions for the control unit are, for example, a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS (for example, OSS (Operation Support System))-IF: (InterFace), and a setting / management application.

  G. In the case of 989.3, for example, as shown in FIGS.

  In the case of the DBA application, the middleware 120 shown in FIGS. 1 and 3 or the basic function 132 shown in FIGS. 4 and 5 operates the Embedded OAM Engine that is hardware of the TC layer. And the transmission / reception part which is the hardware of a PMD layer receives according to a DBA application. In addition, when a transmission / reception part also receives the upstream signal which does not follow DBA, you may not follow DBA application.

  The information processing unit is not limited to these software functions, and may have other software functions. The hardware is not limited to the transmission / reception unit, OSU, switch, control unit, and information processing unit. For example, the information processing unit may be included in a transmission / reception unit, an OSU, a switch, or a control unit.

  Further, as shown in a diagram of a configuration example described later, a proxy unit or an external server that processes a signal input to and output from the switch may be provided on the NNI (Network-Network Interface) side of the switch. The external server may have an information processing function called a so-called cloud such as a data center including a plurality of devices.

  Each function may be appropriately arranged according to a request for processing capacity or processing delay. The OSU may include a switch (a switch unit 12 or a switch unit 13 described later), or may include a switch (a switch unit 12 in the case of including the switch unit 13 described later) separately from the switch. It is desirable that the switch functions are appropriately shared according to the processing capacity of the switch without overlapping between the switch unit 12 and the switch unit 13, but may be overlapped.

  The place where the softening function is provided is not limited to the information processing unit, and may be provided at a place where a plurality of arithmetic processes can be performed. For example, the location where the softwareization function is deployed is other than the transmission / reception unit, the OSU switch, the OSU switch, the OLT control unit, the OLT switch, the OLT information processing unit, the OLT switch, the control unit, and the information processing unit. Either a proxy unit that processes signals input to or output from the switch on the NNI side of the switch or a processing device such as an external server may be used.

  Further, the arrangement of the softening function may be arranged for each softening function, or may be a part of the softening function obtained by dividing a single softening function. For example, the part related to the transmission / reception unit other than the transmission / reception unit, for example, the switch of the OSU, the transmission / reception unit of the OSU and other than the switch, the switch of the OLT, the control unit of the OLT, the information processing unit of the OLT, It may be deployed somewhere or a combination of a plurality of deployment locations such as a proxy unit and an external server on the main signal path outside the OLT. Items related to PON termination other than PON termination processing deployment locations, for example, OSU transmission / reception unit, OSU switch, other than OSU transmission / reception unit and other than switch, OLT switch, OLT control unit, OLT information processing unit Other than that of the OLT, the proxy unit may be deployed outside the OLT, or on a combination of a plurality of deployment locations such as a proxy unit or an external server on the main signal path.

  Items related to ONU switches other than ONU switches, for example, transmission / reception unit, other than OSU transmission / reception unit and other switches, OLT switch, OLT control unit, OLT information processing unit, other than OLT, OLT It may be deployed somewhere on the main signal path outside the network such as a proxy unit, an external server, or a combination of a plurality of deployment locations. OLT switches related to OLT switches other than OLT switches, for example, transmission / reception unit, OSU switch, other than OSU transmission / reception unit and other switches, OLT control unit, OLT information processing unit, other than OLT, OLT It may be deployed somewhere on the main signal path outside the network such as a proxy unit, an external server, or a combination of a plurality of deployment locations.

  Further, the location where the softening function is deployed may be changed as appropriate according to the status of the deployment of the extended function, the computing capability, computing load, power consumption, etc. of the location where computation is possible.

  As an example of dividing the function into an implementation unit and an instruction unit and processing the divided part as another device or software, the function of dynamic bandwidth allocation (DBA), which is a function provided for the OLT of the PON access control function, is used. Show. Here, in the configuration of FIGS. 1 and 3, the device-dependent unit 110 functions as an implementation unit, and the device-independent application 130 serves as an instruction unit. Both may be the device dependent unit 110. Examples of both device-independent applications 130 include, for example, an information processing unit such as a processor provided with a power transmitter / receiver having an implementation unit for functions such as DBA processing, and an instruction unit provided with a powerful information processing capability. This is a case where inter-processor communication or inter-device communication between devices operates as middleware 120 in preparation for an information processing unit such as an OSU. When both are provided in the device dependence unit 110, the DBA function is compiled as a part of firmware or the like, as in the example on the left.

  The implementation unit repeats a fixed process, and when the instruction unit is not ideal in the processing result of the implementation unit, it is corrected by the process of the instruction unit or corrected by instructing the implementation unit to be an ideal process. Move closer. DBA, DWA, DWBA, main signal processing, and the like are suitable for such functional processing. Alternatively, the implementation unit provisionally responds to the provision of response time, and the instruction unit performs a true response. Appropriate for such functional processing includes authentication and switching. This DBA example corresponds to the former correction and can be similarly applied to DWA and DWBA.

  In the following, explanation will be made on the assumption of guaranteed allocation, non-guaranteed allocation, and best-effort allocation in the case of loose specifications such as delay variation, maximum delay, etc., but if the allocation of fixed allocation or delay is severe, the allocation is performed according to the regulations. Also, it is desirable to exchange profiles, etc., clarify the IF to be used, parameters, and their ranges, and continue the exchange. The configuration of the device dependence unit 110, the implementation unit, the instruction unit, and the exchange between the next execution unit and the instruction unit It is desirable to perform IF conversion and parameter conversion as necessary, such as the delay time required for the communication, the bandwidth, and whether the communication line can be occupied.

  The implementation unit continues the allocation while switching a predetermined band or a plurality of predetermined bands to the same destination, or switching a predetermined band setting or a predetermined band setting. The instruction unit detects a predetermined operation of the implementation unit, and performs DBA according to a difference between the detection result and a desired allocation. The predetermined operation is, for example, assignment or assignment result or assignment history or data continuity or conduction history or request or request history associated with assignment. For example, the DBA may instruct the execution unit to specify a predetermined band, to instruct allocation suppression or priority allocation for a part of the allocation target, to instruct to change the band setting, or to The priority order is instructed, or switching of a predetermined band is instructed.

  The predetermined bandwidth is, on average, a fixed bandwidth setting for each allocation target (for example, an ONU or an ONU queue) as a lower limit, a maximum bandwidth setting as an upper limit, and an allocation history for a predetermined period approaches a desired bandwidth. Set to.

  The predetermined period is preferably longer than the time required for the execution unit to change the predetermined band upon receiving an instruction from the instruction unit. For example, it is several to several tens of times and is the time required for multiple changes. Further, it is desirable that the time is such that the user does not feel a difference from the desired band. For example, it is desirable that the time unit for measuring the bandwidth is, for example, 1 second or less.

  The allocation history for a predetermined period is an index average, a moving average, an average in which the history is reset at a predetermined interval, and a history obtained by performing other statistical processing.

  The allocation of the implementation department or the result of assignment is the information from the implementation department, the measurement at some point, the retention information for reporting to the higher system, or the history of past instructions, OAM, backboard, internal wiring and main signal It inputs from the history of the instruction | indication which hold | maintains in an input or an instruction | indication part via wiring, exclusive wiring, routes, such as EMS and a Cont version. The history may be accumulated by other than the instruction unit.

  Data continuity or continuity history is reported from the implementation department, measured at any point, or retained information for reporting to the host system. Internal wiring, backboard, OAM, main signal line, dedicated wiring, EMS, Cont Input via a route such as a version. The history may be accumulated by other than the instruction unit.

  The request or request history is input from the ONU, or a copy of the report, directly terminated at the instruction section or terminated at any point, and the internal wiring, backboard, OAM, main signal line, dedicated wiring, EMS, Input from the Cont version or other route or use of the allocated bandwidth (if there is an unused portion of the allocation, the used portion is requested, and if there is no unused allocation (if it is all used), it is requested more than the allocation) from the implementation department , Or information held in any place or information held in the host system or history of past instructions, internal wiring, backboard, OAM, main signal line, dedicated wiring, EMS, Cont version, etc. From the history of instructions that are input or held by the instruction unit. The history may be accumulated by other than the instruction unit.

  The request or request history may predict a future request or a band that should have been originally allocated but not allocated from the input allocation or allocation history or data continuity or continuity history or allocation result or request or request history. . The prediction may be made by statistical processing such as a linear function or a quadratic function, or a behavior such as TCP that takes into account RTT that is set in consideration of past requests, results of allocation use, distance to the server, and the like. It may be predicted based on the above, or it may be predicted as guaranteed bandwidth setting if there is no unused allocation. If there is no unused allocation, the guaranteed bandwidth setting is non-zero or the fixed bandwidth setting is subtracted from the guaranteed bandwidth setting. Bandwidth where the value is non-zero and there is no unused allocation or the guaranteed bandwidth setting exceeds the guaranteed bandwidth setting and the non-guaranteed bandwidth is allocated according to the guaranteed bandwidth setting or the value obtained by subtracting the fixed bandwidth setting from the guaranteed bandwidth setting If there is no unused allocation, it may be predicted that there is no unused allocation or that the guaranteed bandwidth setting is exceeded and the best effort bandwidth is allocated to the requested allocation target. Moreover, you may predict combining a some prediction method.

  The desired bandwidth is determined according to a predetermined ratio, up to the bandwidth that is added to the requested allocation target, the predicted value of the request or the request, or the bandwidth for detecting a deviation from the predicted value of the request or the request. The band is sufficient. The predetermined ratio is, for example, a ratio of a guaranteed band setting or a value obtained by subtracting the fixed band setting from the guaranteed band setting. The predetermined band may be set in units of TRx such as for each wavelength, for each code, for each carrier frequency, or for each core wire, or for an OSU unit or OSU in which TRx such as a plurality of wavelengths, codes, carrier frequencies, or core wires are bundled. It may be set in units of switches, or may be set in units of switches in which TRx or OSUs such as a plurality of wavelengths, codes, carrier frequencies, or cores are bundled, or the upper NW (network) band is shared. You may set by the allocation object unit. It is desirable that the desired bandwidth has an upper limit on the maximum bandwidth setting for each allocation unit, and if there is a total bandwidth setting as TRx or a bundle, it is desirable that the upper limit be set.

  As a method of bringing the allocation history of a predetermined period closer to the desired band, the difference is divided into single or multiple predetermined periods from the desired band to the allocation target having a low allocation history of the predetermined period from the desired band. Priority allocation / allocation suppression, bandwidth setting change, allocation order change, allocation band switching may be performed even if the added bandwidth is added up to the maximum bandwidth setting, and the expected and required bandwidth is requested and requested Priority allocation / allocation suppression, bandwidth setting change, allocation order change, allocation band switching even if the bandwidth obtained by dividing the difference by one or more predetermined periods is added to the allocation target with a low allocation history for a predetermined period It is also possible to set the guaranteed bandwidth of the allocation target to the allocation target whose allocation history is low for a predetermined period from the desired bandwidth and predicted to be requested, or for priority allocation / allocation suppression, bandwidth setting change. , Change assignment order The allocated band may be switched, and the non-guaranteed allocated band or the best-effort band is set for the guaranteed band setting of the allocation target for the allocation target having a low allocation history for a predetermined period from the desired band with the prediction of requested or requested Alternatively, the predicted value may be a value obtained by adding a band apportioned according to the allocation target, or priority allocation / allocation suppression, band setting change, allocation order change, and allocation band switching may be performed.

  Preferential allocation even if the bandwidth obtained by dividing the difference by a single or multiple predetermined periods is subtracted with the fixed bandwidth setting as a lower limit to the allocation target with a high allocation history for a predetermined period from the expected or required band -Allocation suppression, bandwidth setting change, allocation order change, allocation bandwidth switching may be performed, and the difference is simply applied to allocation targets that are predicted to be requested or requested and have a high allocation history for a predetermined period from the desired bandwidth. Even if the bandwidth divided by one or more predetermined periods is subtracted, priority allocation / allocation suppression, bandwidth setting change, allocation order change, allocation bandwidth switching may be performed, Priority allocation / allocation suppression, band setting change, allocation order change, allocation band switching may be performed as a guaranteed band setting or fixed band setting for the allocation target to an allocation target having a high allocation history for a predetermined period from a desired band. Requested or required From the bandwidth that is allocated to the guaranteed bandwidth setting of the allocation target for the allocation target with a high allocation history for a predetermined period from the predicted bandwidth and the desired bandwidth to the non-guaranteed allocated bandwidth or the best effort bandwidth or its predicted value according to the allocation target However, priority allocation / allocation suppression, bandwidth setting change, allocation order change, allocation band switching may be performed as a value with less bandwidth added. As guaranteed band setting or fixed band setting, priority allocation / allocation suppression, band setting change, allocation order change, and allocation band switching may be performed.

  The predetermined bandwidth is a single or plural BWMap form, an allocation time for each allocation unit such as T-CONT, Alloc-ID, and LLID, a combination of start time and allocation time, T-CONT, Alloc-ID, LLID, etc. Allocation may be performed by a combination of allocation time and allocation order for each allocation unit. Transmission from the instruction unit to the implementation unit may be performed by giving an identifier such as a predetermined bit string so as to be distinguished from other information, may be transmitted in the form of Embedded OAM, or OAM A frame, an MPCP frame, a predetermined VID, MAC address, TOS / COS, a combination thereof, a frame or a cell that can be identified by a VP or VC may be exchanged. The instructing unit has a function of giving an identifier, encapsulating, or communicating via a predetermined communication path so that the processing unit can be identified, and receiving a communication through the identification, decapsulation, or predetermined communication path so that the processing unit can be identified. It has a function. The input / output from the processing unit to the instruction unit is the same, and unless the instruction unit directly terminates the report from the ONU, the function of processing so that it can be received and input to the instruction unit is on the path where the declaration is exchanged. Prepare for.

  In the above description, the instruction from the instruction unit is shown in a form depending on the vendor and the system. However, in the first embodiment of the present invention, middleware is used, and in the second embodiment of the present invention, the middleware and, in some cases, the device-dependent application are used. In this embodiment, the device-dependent unit is an instruction to convert the format of the vendor-independent API 21 through the vendor-dependent API 21 by the device-dependent unit and, in some cases, the device-dependent unit in the fourth embodiment of the present application. The instruction unit of the present application gives an instruction according to the vendor independent API 21. For example, in the case of bandwidth allocation, an instruction is given in a format that does not depend on the vendor and method that can be converted into the form of ITU-T BWMap or the form of transmission permission time and transmission duration for each IEEE LLID. Also, in order to accommodate multi-services, it also conveys rules such as jitter, burst, and average time of average bandwidth. In the above description, the DBA has been described. However, the same applies to functions that constitute a PON access function other than the DBA and functions other than the PON access function.

  For example, in the case of the L2 function, the device-independent API 21 instructs only the switching of wavelengths for exchanging data of the same path, and the wavelength switching vendor-dependent API 21 as a specific process, the paths before and after the wavelength switching are Encapsulate the tag in common and transmit it between the switch and the ONU, remove the tag and decapsulate it, or convert the tag between the wavelengths according to a predetermined conversion rule, transmit and convert between the switch and the ONU, The device-dependent API 23 (in the case of the second embodiment, the same as the device-dependent API 23) is operated so that a path change is predicted or notified in advance and is switched in advance or in synchronization with the switch and the ONU. Device-dependent API 24 via a device-dependent application or all device-dependent apps, device-independent API 27 in the case of the third embodiment, device-independent A in the case of the fourth embodiment I27 with some or all indicated by device-dependent API 24) via a device-dependent application.

  For example, in the case of the multicast function, the device-independent API 21 instructs only the switching of wavelengths for exchanging data of the same path, and as one of the specific processes, the filter setting is performed by the device-dependent API 23. The path before and after the wavelength switching is set to a common filter between wavelengths, converted to a predetermined filter with a predetermined conversion rule between wavelengths, or predicted or notified in advance and switched or synchronized in advance with the ONU. Device-dependent API 23 (in the case of the second embodiment, the device-dependent API 23 and the device-dependent API 24 through a part or all of the device-dependent applications, in the case of the third embodiment, so as to operate the part depending on the vendor or the system. Is a device-independent API 27, and in the case of Example 4, a device-independent API 27 and a device-dependent API 24 via a part or all of a device-dependent application) It instructs.

  An example in which a true response is performed by the instruction unit is, for example, a case where an external server or the like performs a check as to whether a registered ONU is appropriate. First, the execution unit registers the ONU, and makes an inquiry to the instruction unit for optimization via the device-dependent API 23 and the device-independent API 21. If there is an ONU-OLT communication until the answer to the inquiry is returned, the necessary communication such as a health check is continued without transferring user data. If only bandwidth allocation is necessary, bandwidth allocation is performed and data is retained in the OLT. If a response to the user data is necessary, it is represented by the implementation unit or the instruction unit. In the case of the forced switching sequence, there is no response delay by setting the switching time in the implementation unit in advance in the instruction unit before the response time by the instruction unit, and starting the processing in advance by the response time delay. Like that.

  As described above, this embodiment defines past functions by defining at least some functional modules and input / output IFs, clarifying the functions to be ported between generations, and ensuring versatility and portability. By clarifying general-purpose functions among equipment vendors, they can be shared by vendors, thereby avoiding double development and reducing development and procurement costs.

Same as 1.

(Embodiment 1-3)

The WDM-PON is the same as the embodiment 1-1 except that it does not have to have the function of time-division multiplexing the bandwidth resources of the ONU-OLT PON section between ONUs such as DBA.

(Embodiment 1-4)
In the embodiment 1-1, the configuration used for the TWDM-PON is exemplified, but it may be applied to a PON sharing resources other than the wavelength and time.

(Embodiment 2)
FIG. 3 shows an example of the architecture of the communication apparatus according to the second embodiment. The communication apparatus according to the present embodiment includes a device-dependent application 160 under the middleware 120. Except for the provision of the device-dependent application 160, this is the same as in the first embodiment. By providing the device-dependent application 160, there is an effect that the configuration of the middleware 120 can be simplified. The middleware 120 and the device dependent application 160 are connected by a device dependent API 23. The device-dependent application 160, the OAM 114, and the software 113 are connected by a device-dependent API 24. The device independent applications 130 (for example, the extended function A 131-1 and the basic function 132) are connected via the middleware 120 as necessary. In FIG. 3, the EMS 140 and the other device 150 are connected to the middleware 120. However, the EMS 140 and the other device 150 are not necessarily connected to the middleware 120. The EMS 140 and the other device 150 may be appropriately connected to the middleware 120 as necessary. In addition, although expressed as “connection via the middleware 120”, this expression is an expression from the viewpoint viewed from the device-independent application 130. Actually, the function-independent applications are connected to each other via the middleware 120 after the connection with the hardware.

  As shown in FIG. 3, hardware 113 depending on the standard depending on the standard or the manufacturing vendor conforming to the device dependent unit 110 from the bottom, software 113 of the device dependent unit 110 such as a driver / firmware driving the hardware, and the hardware of the device dependent unit 110. A device-dependent application 160 that drives at least a part of hardware and software, middleware 120 that conceals the difference between the hardware and the device-dependent application 160, and a general-purpose device-independent application 130 that does not depend on the device.

  The device-independent application 130 includes, for example, a management / control agent 133 that receives communication from the EMS 140 via the middleware 120, a basic function 132, an extended function A 131-1, an extended function B 131-2, and an extended function C 131-3. is there. However, the device-independent application 130 may not include all of these, or may include more. For example, when the extended function is unnecessary, the extended function A 131-1, the extended function B 131-2, and the extended function C 131-3 may be omitted. Moreover, it is preferable that an extended function can be added or deleted. For example, in accordance with service requirements, for example, when an extended function is a multicast service or a power saving function, the extended function may be added as needed.

  The basic function 132 may be included as a part of the extended function, or may be replaced by the middleware 120 subordinate. When the extended function includes the basic function 132, when the middleware 120 subordinate replaces the basic function 132, or a combination thereof, the device-independent application 130 may not include the basic function 132. Also, a part of the basic function 132 may be replaced with a device-dependent application under the middleware 120. The management / control agent 133 does not need to input / output from / to the EMS 140 via the middleware 120 in the case where the automatic setting is performed according to the preset setting without receiving the communication from the EMS 140 via the middleware 120. Furthermore, when the management / control agent 133 is not provided with the management / control agent 133 and the other device-independent application 130, the basic function 132, or the device-dependent unit 110 is provided, the management / control agent 133 may not be provided. Conversely, the EMS 140 may directly input / output each function independent application via the middleware 120. When the middleware 120 subordinate replaces all of the basic functions 132, the device-independent application 130 has an architecture that does not include the basic functions 132.

  The device-dependent application 160 may be input / output from the management / control agent 133 via the middleware 120, or may be directly input / output from / to the EMS 140. When the device-dependent application 160 is managed and controlled via the middleware 120 without being communicated from the EMS 140 via the middleware 120 and automatically set according to the preset settings, the management / control agent 133 may not be provided.

  The device-independent application 130 inputs and outputs with at least the hardware or software 113 of the device-dependent unit 110 via the middleware 120. The device-independent application 130 inputs and outputs to / from each other via the middleware 120 as necessary. In particular, the device-independent application 130 inputs and outputs with the management and control agent 133 that receives communication from the EMS 140 when performing control and management according to the input and output from the EMS 140.

  The NE management / control unit inputs / outputs NE management / control information to / from the management / control agent 133 via the middleware 120. The NE management / control unit may directly exchange NE management / control information with the EMS 140 without using the middleware 120. The device-dependent application 160 inputs and outputs NE management / control information with the management / control agent 133. The device-dependent application 160 may directly communicate with the EMS 140 without using the management / control agent 133.

  As in the architecture shown in FIG. 1, the device-independent application 130 is an application that operates regardless of the device vendor and does not depend on the difference in device generation. Thus, an application for driving a function provided in some devices or an application for driving a function provided only in some generation devices may be included.

  The management / control agent 133 performs input / output with the EMS 140, the middleware 120, and the device-dependent application 160. The middleware 120 inputs and outputs NE management / control information with the NE management / control unit. The NE management / control unit may directly exchange NE management / control information with the EMS 140 without using the middleware 120. The middleware 120 inputs and outputs via the device-independent application 130 and the device-independent API 21, and inputs and outputs via the device-independent API 21 with the OAM, driver, firmware, and hardware of the device-dependent unit 110.

  The middleware 120 is input as it is or in a predetermined format, similarly to the architecture shown in FIG.

  As with the architecture shown in FIG. 1, it is desirable that the device-independent API 21 is provided in the middleware 120 in advance, assuming an extended function to be added later. However, the device-independent API 23 and other device-independent APIs are used as necessary. You may add and delete in the form which suppresses the modification | change of the application 130. FIG.

2 may be an ONU, like the architecture shown in FIG. 1, or may be either an PON OLT or an ONU compliant with ITU-T recommendations other than TWDM-PON, PONs conforming to IEEE standards such as GE-PON and 10GE-PON may be used, and the TC layer and PMD layer are the same if they are read as corresponding layers.
Examples in which the configuration of FIG. 3 is embodied are shown in FIGS. The device-independent application 130 in FIG. 3 corresponds to a FASA application such as a DBA algorithm, a DWA algorithm, and a setting management application, and the middleware or lower corresponds to a portion below the FASA high-speed API or FASA low-speed API or a driver that drives hardware or the like. To do. The API is exemplified by the FASA high-speed API and the FASA low-speed API, but is not limited to these, and the configuration may be different. In the figure, an HW (hardware) dependent driver and an adaptation layer are included. However, if the driver can be directly driven by the FASA high-speed API or the FASA low-speed API, it is unnecessary and approaches the configuration of FIG. FIG. 28 shows an example in which the device-independent application 130 of FIG. 1 or FIG. 3 is rewritten using a FASA application and the middleware 120 and the device-dependent unit 110 below the device-independent API are used as the FASA base. This figure shows FASA applications, FASA-APIs such as FASA high-speed API and FASA low-speed API, and FASA infrastructure corresponding to the parts below FASA-API such as FASA high-speed API and FASA low-speed API shown in FIGS. Is shown.
Examples in which the configuration of FIG. 3 is embodied are shown in FIGS. The device-independent application 130 in FIG. 3 corresponds to a FASA application such as a DBA algorithm, a DWA algorithm, and a setting management application, and the middleware for the FASA application API corresponds to a portion below the FASA application API or a driver that drives hardware, etc. To do.
FIG. 34 is a configuration example of an access network device based on FASA taking NG-PON2 OLT as an example. The figure shows an example in which the FASA base is configured by a plurality of hardware (NG-PON2 box, white box switch). The NG-PON2 box and the white box switch were connected by a standard protocol such as Ethernet. The addition or replacement of functions is performed by adding or replacing the FASA application on the FASA-based FASA application API. The FASA application API middleware is software for providing a FASA application API by absorbing differences in hardware and software due to differences in vendors and systems.
The API is exemplified by the FASA application API, but is not limited thereto, and the configuration may be different. In the figure, the HW (hardware) -dependent driver, the chip-dependent SDK, and the middleware for FASA application include an adaptation layer. However, if the driver can be driven directly by the FASA application API, the adaptation layer is not necessary and approaches the configuration of FIG. . 37 shows an example in which the device-independent application 130 in FIGS. 1 and 3 is rewritten as a FASA application, and the FASA application API middleware 120 and the device-dependent unit 110 below the device-independent API are used as the FASA base. It is an example. In this figure, the FASA application, the FASA application API, and the FASA base corresponding to the portion below the FASA application API of FIGS. 34, 35, 36, and 37 are shown.
FIG. 37 shows a replacement image of the original specification by replacing the FASA application as a use case of FASA. Shows the realization of carrier-specific specifications by replacing FASA applications. In this example, in order to cope with functions that are used differently for each telecommunications carrier, not all combinations are mounted in advance, but an access network device having a desired function by replacing the FASA application as necessary. I will provide a. For example, power saving and protection. In the case of protection, high availability is required for the access system as a carrier requirement. For example, the protection function is important because it is necessary to perform the service without stopping even when the access network device is updated and software is migrated to successor hardware with improved processing performance. FASA defines a protection API because protection is assumed to be performed by a different method or different policy for each communication carrier.
As a use case of FASA, multi-service accommodation by replacing the FASA application can be considered. This is an example for efficiently providing multi-services such as mobile, mass, and business using the PON system. The requirements for each service are very different. In particular, the maximum allowable delay for the main signal of the mobile fronthaul (MFH) is stricter than, for example, conventional Internet access services. By replacing the FASA application, services with greatly different requirements such as mobile, mass, and business are accommodated in the PON system. One typical example is DBA. The DBA that allocates the upstream band of the PON needs to satisfy a strict delay rule. In FASA, DBA corresponding to each service is provided by FASA application replacement.

FIG. 4 shows an example of the architecture of the communication apparatus according to the third embodiment. In this embodiment, instead of the middleware 120 described in the first embodiment, the basic function 132 exchanges with hardware or an extended function. That is, the basic function 132 functions as an interface that connects the device-dependent unit 110 and the device-independent application 130. The basic function 132 also functions as an interface for connecting functions included in the device-independent application 130 (for example, the extended function A 131-1 and the extended function B 131-2). Other device-independent applications 130 are the same as those in the first embodiment. Compared to the first embodiment, it is not necessary to create each device with a different standard, generation, method, system, device type, or manufacturing vendor that complies with the middleware 120 having the device-dependent API 24. As a result, more functions can be generalized and ported easily, verification of connectivity is easy, and the functions of the device are robust. The basic function 132 and each extended function are connected by a device independent API 22, and the basic function 132 and the device dependent unit 110 are connected by a device independent API 27. The extension functions of the device-independent application 130 (for example, the extension function A 131-1 and the extension function B 131-2) are connected via the basic function 132 as necessary. In FIG. 4, the EMS 140 and the other device 150 are connected to the basic function 132. However, the EMS 140 and the other device 150 are not necessarily connected to the basic function 132. The EMS 140 and the other device 150 may be appropriately connected to the basic function 132 as necessary. In addition, although expressed as “connection via the basic function 132”, this expression is an expression from the viewpoint viewed from the device-independent application 130. Actually, the extension functions of the function-independent application are connected to each other via the basic function 132 after the connection with the hardware.

  As shown in the figure, a device dependent unit 110 and a device independent application 130 are configured from the bottom. The device-dependent unit 110 includes hardware that depends on a compliant standard, a device manufacturer, or the like, or software such as a driver / firmware that drives the hardware. The driver or the like hides the difference between the device dependent units 110. The device-independent application 130 is connected to the device-dependent unit 110 via a porting IF (device-independent API 27) and a driver that conceals the difference between the hardware and software 113 of the device-dependent unit 110. And a general-purpose device-independent application 130 that does not depend on the device. The device-independent application 130 inputs and outputs data to and from the hardware and device-dependent software via a driver that conceals the difference between hardware and device-dependent software.

  A basic function 132 in the device-independent application 130 exchanges a device-dependent portion such as hardware with an extended function instead of the middleware 120. The basic function 132 may include a management / control agent 133 that receives communication from the EMS 140, or may include the management / control agent 133 as an extended function. The basic function 132 inputs / outputs from / to other device-independent applications 130 via the device-independent API 22, and the OAM, driver, firmware, hardware, device-independent API 27, and device-dependent unit 110 driver of the device-dependent unit 110 are input and output. Input and output.

  As with the middleware 120 shown in FIG. 1, the basic function 132 is input as it is or in a predetermined format. For example, the device-independent application 130 is converted into the device-independent API 22 format of the input format, and the OAM, driver, firmware, or hardware of the device-dependent unit 110 is input into the format. The data is converted into the device-independent API 27 format or terminated and subjected to predetermined processing and input. At the time of input, unnecessary input information is deleted at each input destination, and if there is insufficient information, it is desirable to collect and supplement via other device-independent API 22 or device-independent API 27. May be broadcast or multicast and broadcast to related applications.

  The device-independent application 130 is, for example, a basic function 132, an extended function A131-1, an extended function B131-2, and an extended function C131-3. However, the device-independent application 130 may not include all of these, or may include more. For example, when the extended function is unnecessary, the extended function A 131-1, the extended function B 131-2, and the extended function C 131-3 may be omitted. Moreover, it is preferable that an extended function can be added or deleted or replaced or changed independently without affecting other functions. For example, when an extension function is required for a multicast service or power saving function, for example, according to service requirements, it is added as needed when the extension function is needed, deleted as needed, and changed according to the change. It may be replaced or changed.

  When the automatic setting is performed according to the pre-set without receiving the communication from the EMS 140, the basic function 132 may not include the management / control agent 133 or the management / control agent 133 equivalent. The extended function of the device independent application 130 is input / output via the basic function 132 and at least via the device independent API 22. The device-independent application 130 inputs and outputs to / from each other via the basic function 132 as necessary. In particular, when the management / control agent 133 that receives communication from the EMS 140 is an extended function, input / output is performed via the management / control agent 133 and the basic function 132. The management / control agent 133 may input / output NE management / control information via the NE management / control (not shown) and the basic function 132, or NE management / control (not shown) without input / output. And EMS 140 may communicate directly or via conversion.

  Similar to the architecture shown in FIG. 1, the device-independent application 130 is an application that operates without depending on the device vendor and regardless of the difference in device generation. However, as an extended function application, the device-independent application 130 is connected via the device-independent API 22. In addition, an application for driving a function included in some devices and an application for driving a function included only in some generations of apparatuses may be included.

  It is desirable that the device-independent API 22 is provided in advance in the basic function 132 assuming an extended function to be added later. However, if necessary, the device-independent APIs 22 and 27 and other device-independent applications 130 may be modified. You may add and delete in a suppressed form.

  3 may be an ONU, like the architecture shown in FIG. 1, or may be either an PON OLT or ONU compliant with ITU-T recommendations other than TWDM-PON, PONs conforming to IEEE standards such as GE-PON and 10GE-PON may be used, and the TC layer and PMD layer are the same if they are read as corresponding layers.

  FIG. 6 shows a comparison between this example and the conventional example. The left side of the figure is conventional and the right side is Example 3. In the conventional example, the carrier / service-specific extended function (unique function) is an individual implementation in which the interface with the basic system is unclear. For this reason, the firmware / software differs from device to device, and if the carrier / service-specific extended function is to be deleted / added / replaced, it is necessary to recreate the firmware / software for each system. In addition, in this embodiment, by providing an extension interface (IF) for implementing an extension function for each carrier / service in the basic system (mainly the basic function 132 therein), an extension function for each carrier / service (unique function) ) Can be easily deleted / added / replaced. Further, by providing a porting interface (IF) that conceals device dependence between the basic function 132 and the device dependence unit 110 in the basic system, the basic function 132 and further expanded functions (unique functions) by carrier / service thereon. ) Can be shared between different crises.

(Embodiment 4)
FIG. 5 shows an example of the architecture of the communication apparatus according to the fourth embodiment. The difference between the present embodiment and the third embodiment is that there is a device-dependent application 160 under the basic function 132. By providing the device-dependent application 160, there is an effect that the configuration of the basic function 132 can be simplified.

  As shown in the drawing, from the bottom, hardware that depends on a standard that conforms to the device-dependent unit 110 or a device manufacturer, software such as a driver / firmware that drives the hardware, at least part of hardware of the device-dependent unit 110, or The device depends on the device-dependent application 160 that drives at least a part of the software, the porting IF and the driver that conceals the difference between the hardware and software 113 of the device-dependent unit 110, or the porting IF and the device-dependent app 160 A general-purpose device-independent application 130 is provided without depending on. The basic function 132 and the device-dependent application 160 are connected by a device-independent API 27, and the device-dependent application 160 and the device-dependent unit 110 are connected by a device-dependent API 24. The extension functions of the device-independent application 130 (for example, the extension function A 131-1 and the extension function B 131-2) are connected via the basic function 132 as necessary. In FIG. 5, the EMS 140 and the other device 150 are connected to the basic function 132. However, the EMS 140 and the other device 150 are not necessarily connected to the basic function 132. The EMS 140 and the other device 150 may be appropriately connected to the basic function 132 as necessary. In addition, although expressed as “connection via the basic function 132”, this expression is an expression from the viewpoint viewed from the device-independent application 130. Actually, the extension functions of the function-independent application are connected to each other via the basic function 132 after the connection with the hardware.

  The basic function 132 in the device-independent application 130 communicates with the hardware and the extended function instead of the middleware 120. The basic function 132 may include a management / control agent 133 that receives communication from the EMS 140, or may include the management / control agent 133 as an extended function. The basic function 132 is input / output from / to another device-independent application 130 via a device-independent API 22 (extension IF), and the OAM, driver, firmware, hardware, and device-independent API 27 of the device-dependent unit 110 (for porting) IF) and the device dependent unit 110 that conceals the difference between the device dependent unit 110 and the device dependent application 160 and the device dependent API 24.

  As with the middleware 120 shown in FIG. 1, the basic function 132 is input as it is or in a predetermined format. For example, the other device-independent application 130 is converted into the device-independent API 22 format of the format to be input to each, and the OAM, driver, firmware, or hardware of the device-dependent unit 110 is input to each. The format is converted into the device-independent API 27 format, or terminated and subjected to predetermined processing and input. When inputting, unnecessary input information is deleted at each input destination, and if there is insufficient information, it is desirable to collect and supplement via other device-independent APIs 22 and 27 and device-dependent API 24. The input may be broadcast or multicast to be broadcast to related applications.

  The device-independent application 130 is, for example, a basic function 132, an extended function A131-1, an extended function B131-2, and an extended function C131-3. However, the device-independent application 130 may not include all of these, or may include more. For example, when the extended function is unnecessary, the extended function A 131-1, the extended function B 131-2, and the extended function C 131-3 may be omitted. Further, it is preferable that the extended function can be added, deleted, replaced, or changed independently of each other without affecting other functions. For example, when an extended function is required for a multicast service or power saving function, for example, in accordance with service requirements, it may be added as appropriate when the extended function becomes necessary, or may be deleted when it becomes unnecessary. It may be replaced or changed when necessary.

  A part of the basic function 132 may be replaced with the device-dependent application 160. When the automatic setting is performed according to the pre-set without receiving the communication from the EMS 140, the basic function 132 may not include the management / control agent 133 or the management / control agent 133 equivalent. The extended function of the device-independent application 130 is input / output through the basic function 132 and at least through the device-dependent API 24. The device-independent application 130 inputs and outputs to / from each other via the basic function 132 as necessary. In particular, when the management / control agent 133 that receives communication from the EMS 140 has an extended function, the management / control agent 133 performs input / output. The management / control agent 133 may input / output NE management / control (not shown) and NE management / control information, or without input / output, the NE management / control (not shown) and the EMS 140 may be directly or directly You may communicate via conversion.

  Similar to the architecture shown in FIG. 1, the device-independent application 130 is an application that operates regardless of the device vendor and does not depend on the device generation, but as an extended function application, the device-independent API 22 An application for driving a function provided for some device vendors and an application for driving a function provided only for some generations of apparatuses may be included.

  It is desirable that the device-independent API 22 is provided in advance in the basic function 132 assuming an extended function to be added later. However, the device-independent APIs 22 and 27, other device-independent applications 130, and device-dependent are provided as necessary. You may add and delete in the form which suppresses the modification of the application 160 or the device dependent API 24.

With the configuration configured as described above, communication is performed via the middleware or basic function interface. With such a configuration, the dependency relationship between applications can be reduced. For example, it is assumed that communication is performed between applications using a unique interface without using middleware. For example, it is assumed that DBA application A and DWA application A communicate with each other using system A and DBA application B and DWA application B use system B respectively. In this case, when one of the communicating applications is replaced (for example, a set of DBA application A and DWA application B is provided in system A, or DBA application B and DWA application A are provided in system A), DBA application It is unclear whether communication and operation are possible between the DWA application and the DWA application. In this way, when a unique interface is provided, the dependency becomes stronger and the commutability deteriorates. On the other hand, communication between applications is also performed through a common interface of middleware or basic functions, so that deterioration of commutability due to a unique interface can be suppressed. Furthermore, it is possible to solve the problem that communication between applications cannot be performed unless a communication path between applications is set separately from middleware or basic functions.
3 may be an ONU, like the architecture shown in FIG. 1, or may be either an PON OLT or ONU compliant with ITU-T recommendations other than TWDM-PON, PONs conforming to IEEE standards such as GE-PON and 10GE-PON may be used, and the TC layer and PMD layer are the same if they are read as corresponding layers.
The above-described EMS is only a specific example of a controller that controls the OLT from the outside. Instead of the EMS, another configuration for controlling the OLT from the outside, such as an OSS and an operation system, may be used.

  The present invention can be applied to the information communication industry.
