(Embodiment 1)
FIG. 1 is a diagram illustrating a configuration example of a component selection system 1 according to the present embodiment, in which only functional blocks related to the present embodiment are extracted and illustrated. The component selection system 1 includes a device 2 for mounting components, a holding unit 3 for holding components, an information unit 4 for storing compatibility information, a type and a state of the device, and the component compatibility is determined accordingly. And an identification unit 5 for judging. In the component selection system 1 shown in FIG. 1, the functional units of the holding unit 3, the information unit 4, and the identifying unit 5 are provided independently of each other outside the device 2. May be included in the function unit. For example, among the holding unit 3, the information unit 4, and the identification unit 5, the device 2 includes one or more functional units or all functional units, and the functional units not provided in the device 2 are connected to the device 2. An external device may be provided. Further, the same functional unit may be realized by the device 2 and an external device connected to the device 2. Further, the component selection system 1 may include a plurality of devices 2. In this case, the component selection system 1 may include a plurality of arbitrary one or more functional units among the holding unit 3, the information unit 4, and the identifying unit 5. For example, the holding unit 3, the information unit 4, and the identification unit 5 may be provided for each device 2, and an arbitrary functional unit among the holding unit 3, the information unit 4, and the identification unit 5 may be provided in a plurality of devices 2. May be provided.

  The device 2 may be a single virtual device composed of a plurality of devices. For example, when the device 2 is the communication device illustrated in FIG. 8 described below, some of the components of the communication device illustrated in FIG. 8 may be another device. Further, for example, the transmission / reception unit 11, the switch unit 12, the switch unit 13, and the control unit 14 of the communication device illustrated in FIG. 8 may be virtual devices, and the transmission / reception unit 11, the switch unit 12, the switch unit 13, the control unit 14, the proxy unit 15, and the external server 16 may be virtual devices. When a component is provided to the device 2, the component may be provided to the device 2 itself on which the component is mounted, and constitutes another device different from the device 2 on which the component is mounted, for example, one virtual device. The component may be provided to another device, and when the component is used, may be transferred to the device 2 on which the component is mounted.

When the device 2 is a single virtual device including a plurality of devices, the holding unit 3 may be included in the virtual device.
The information unit 4 includes the device 2 for mounting components, the device 2 for mounting components, and any one of devices that constitute one virtual device, or the control unit 14 illustrated in FIG. It may be included considerably or may be independent. Further, the identification unit 5 is a device that mounts a component, any device that configures a device that forms a virtual device with the device 2 that mounts a component, or a control unit 14 in FIG. Etc., or may be independent.

  The components mounted on the device 2 may be hardware components such as software and external components. The hardware component may include software necessary for using the component. The holding unit 3 may hold information on components in addition to or instead of components. The component information indicates, for example, information for specifying the component, a description about the component, and the like.

  The compatibility information held by the information unit 4 includes, for example, an input to the device and an output corresponding to the input, a component compatible with the device (mountable), and a type of the device or a configuration of the device. This is the data of the correspondence table. In addition, the registration may be deleted from the compatibility information for the device whose parts do not match. This is particularly suitable when the time required to determine the suitability of the component takes longer than the time allowed for the registration of the component, or when the firmware mounted on the device 2 is determined or rewritten. The information unit 4 may further hold information on the identifier of the device. The information of the identifier of the device may be set in the compatibility information in association with an input to the device and an output corresponding to the input, a part compatible with the device, a type of the device, or a configuration of the device.

  The identification unit 5 acquires an identifier of the device 2, an input to the device 2, and an output from the device 2 corresponding to the input from the device 2. The identification unit 5 refers to the compatibility information held by the information unit 4 and based on the identifier of the device 2 or the relevance between the input to the device 2 and the output from the device 2 corresponding to the input. Then, the type of the device 2 is determined. In addition to or instead of determining the type of the device 2, the identification unit 5 determines the state of the device 2 based on an input to the device 2 and an output from the device 2 corresponding to the input. The identification unit 5 selects a component having high compatibility with the device 2 based on one or both of the determination result of the type of the device 2 and the state of the device 2. The holding unit 3 presents, recommends, or provides the device 2 with the highly compatible component selected by the identification unit 5.

  The input includes connection of the control system, ONU and other devices, change of the connection configuration, retention of addition / removal of parts, change of the connection status, elapse of a predetermined time after the change, A period of a predetermined time from a predetermined time may be used, and it is not necessary to notify an identifier or the like other than an output corresponding to an explicit input. Alternatively, a request for a component or a predetermined component itself may be input, and a more suitable component may be recommended and provided.

  The identifier is, for example, a vendor ID (Identifier) included in a MAC (Media Access Control) address of the device 2, a model ID of the device 2, a serial ID of a product, and version information such as OS, firmware, and middleware. The vendor ID, model ID, product serial ID, and version information such as OS, firmware, and middleware may be used as information on the type or configuration of the device in the compatibility information. It may be used as specifying information.

  When a MAC address is not used as the identifier and the MAC address is not held by the information unit 4, the information unit 4 or the identification unit is displayed in an IEEE OUI (Organizational Unique Identifier) search page for searching for an unknown MAC address by the vendor. An inquiry may be made from step 5 to supplement the compatibility information. Alternatively, the information unit 4 refers to an external database such as an IEEE OUI search page whenever the registration of the device 2 or the inquiry from the device 2 or the registration of the component inquiry mounted on the device 2 is performed. It may be the same as the address effectively stored in the information section 4. As described above, the component selection system 1 may include the virtual information unit 4. Further, a plurality of devices 2 may share the same information unit 4, a plurality of information units 4 may share the same compatibility information, or an information unit 4 corresponding to another device 2 The compatibility information to be held may be queried.

  An input to the device and an output from the device corresponding to the input for determining the type and state of the device 2 are input according to a model such as a MIB (Management Information Base) or Yang for each device for each manufacturer. And a response.

  Here, “presenting” means indicating a component that can be provided to the device 2 as an option. “Recommended” means that a component that is desirably mounted on the device 2 is indicated as an option. When a component is recommended, it is desirable to also show information on the degree of suitability of the component shown as an option and the frequency and number of times of use for similar other devices. Upon identification of the device 2, information (identifier of the device 2) for identifying the device 2 is notified from the device 2 or a control unit or the like that virtually or actually configures the device 2, and the presentation recommendation is provided. Is also good.

  Information on the degree of component suitability and the frequency and number of times of use for other similar devices are stored in the information unit 4 based on feedback from other devices equipped with the components. In addition, when performing presentation or recommendation, the holding unit 3 may output a component as an option or may output information on a component as an option. Also, providing means, for example, assembling or installing as a part in the device 2, passing the source code to build, deploy, or make a source code in the virtual or actual device 2, To pass an executable file according to an execution environment such as an OS or a language.

  High compatibility means the type of the device 2 to be selected for component selection and the state of the device 2, for example, a combination of other components incorporated or installed in the device 2, the version of the OS, firmware, or middleware. For example, the degree of operability, the processing performance is high, and it is easy to coexist with more other components. Therefore, the information unit 4 stores information about components presented, recommended or provided to another device 2 different from the device 2 to be selected as a component, and information about suitability fed back from the other device 2 equipped with the component. Keep it. The information unit 4 generates or updates suitability information based on information on suitability when a component is mounted on another device 2 of the same or similar type or configuration as the component selection target device 2.

  If there is no feedback or compatibility information from the host device or the like for the part, or if there is not a sufficient number of them, for example, if there is no more than a few pieces of compatibility information for feedback, the identification unit 5 May be identified as nonconforming or deprecated or unknown for that matter. The information to be fed back is not specified, but is inconsistent information such as an error at the time of mounting the component in the virtual or actual device 2, conduction or an error of a main signal or a control signal using the component, or a component. It is desirable to have a function of transmitting information on non-conformity of a service related to the information unit 4 from the virtual or actual device 2 or a controller such as an EMS (Element Management System) of the device 2 to the information unit 4.

When the component is software, the holding unit 3 compiles and deploys software source code and the like according to the type of the device 2, the OS installed in the device 2, the corresponding development environment of the device 2, and the like. May be modified before being presented, recommended or provided. Information such as the type of the device 2, the OS installed in the device 2, and the corresponding development environment of the device 2, etc. may be obtained from the device 2, and may be obtained from the device 2 in the compatibility information or separately from the compatibility information. The information may be stored in the information unit 4 in association with the acquired identifier, the input to the device 2 and the output from the device 2 corresponding to the input. In this way, there is an effect that different components need not be held in accordance with the type of the device 2, the OS installed in the device 2, the corresponding development environment of the device 2, and the like.
In this embodiment, it is possible to mount components corresponding to the device 2.

  As described above, the component selection system 1 presents, recommends, or provides only components that have been confirmed to be compatible with the component selection target device 2 based on the compatibility information. Further, the component selection system 1 corrects the component according to the device when the component is provided. Further, the component selection system 1 generates or updates compatibility information based on information collected from the device that provided the component.

  The device 2 is a communication device that executes communication with another communication device by a signal such as an optical signal passing through a communication network such as an optical fiber network such as a PON. The communication device is, for example, an OLT (Optical Line Terminal: optical line terminal). The communication device may be, for example, an OSU (Optical Subscriber Unit). The communication device may be, for example, a combination of an OLT with or without a switch unit (SW) for switching an optical signal and another switch unit (SW). The communication device may be, for example, a combination of an OLT and an ONU (Optical Network Unit: optical network unit). The communication device may include a plurality of devices. Further, another communication device such as an ONU, a MUX (multiplexer), a DEMUX (demultiplexer), or a switch may be used. The device 2 may be composed of a plurality of components. Each component may be provided in a single device or may be provided in separate devices. The device 2 may be a virtual single device including a plurality of devices. The virtual device may include EMS or the like.

  Next, as an example, the operation and the like will be described on the assumption that the communication device as the device 2 is an OLT of a PON conforming to the ITU-T recommendations such as a TWDM (Time and Wavelength Division Multiplex) -PON system. Here, the TWDM-PON is used, but the PON may be a PON other than the TWDM-PON conforming to the ITU-T recommendations. For example, the PON may be a PON conforming to the IEEE standard such as a GE (Gigabit Ethernet (registered trademark))-PON or a 10 GE-PON. A TC (Transmission Convergence) layer and a PMD (Physical Medium Dependent) layer are the same if they are read as corresponding layers in the standard.

  FIG. 2 is a functional block diagram showing the configuration of the component selection system 50 having the communication device 51. The component selection system 50 includes a communication device 51, a software repository 52, and an information unit 53. The communication device 51 is an OLT connected to one or more ONUs, and is an example of the device 2 in FIG. The software repository 52 includes the holding unit 3 and the identification unit 5 in FIG. The information unit 53 corresponds to the information unit 4 in FIG. 1 and is provided in a device different from the software repository 52, but may be provided in the software repository 52.

  The communication device 51 is provided with hardware or software or a component of the combination or hardware or software. For example, the communication device 51 is realized by using a general-purpose input / output interface (for example, FASA (Flexible Access System Architecture) application API) to perform functions different for each service or each communication carrier. An application that is a software component (for example, a FASA application) and that provides a general-purpose input / output interface to the application and a function that does not require a change according to a service or a request because the application is standardized. And basic components of the network device (for example, FASA platform). Here, by using a general-purpose input / output interface, addition and replacement of functions are facilitated, and services for various requests are provided flexibly and quickly. In this specification, an application is also referred to as an “app”.

  The exchange between the components is performed, for example, through a later-described middleware unit 120, but may use a unique transfer path or means of the communication device 51, or may include OpenFlow, Netconf / YANG, or SNMP (Simple Network Management Protocol). A standardized means such as the above may be used.

  The exchange between components may be any of internal wiring, a backboard, an OAM section, a main signal line, a dedicated wiring, an operation system, a controller, or a control panel (Cont panel). When the exchange between components is directly terminated and input, the exchange may be encapsulated in an OAM unit or a main signal. The exchange between components may be terminated at any point and input via a route such as an internal wiring, a back board, an OAM unit, a main signal line, a dedicated wiring, an operation system, a controller or a control panel. . When using an OAM section or a main signal line, it is desirable to encapsulate the OAM section or the main signal. When the signal passes through the main signal line, it is preferable that the signal is distributed by the OSU or another switch unit.

  In the present embodiment, the communication device 51 further includes an interface for receiving software components output from the holding unit 3 by an application such as a FASA application or a platform such as a FASA base, or an interface for inputting an identifier to the identification unit 5.

  The replacement of components such as the FASA application belongs to one of a plurality of used surfaces and a spare surface, and a surface may be selected, or one of the plurality of components may be in an execution state. When any of the components is set to the execution state, for example, the communication device 51 may include an execution area, a file system area, and the holding unit 3 and perform the following operations (1) to (8).

(1) Add: Transfer the component from the holding unit 3 to the file system area. Or, transfer and install. Further, the file of the FASA application may be transferred by FTP / TFTP (File Transfer Protocol / Trivial File Transfer Protocol), or the file of the FASA application may be installed, made, or built. When the transfer and the installation, the make, or the build are different procedures, the installation, the make, or the build procedure may be separately provided. When transferring, installing, etc., the corresponding parts may be overwritten or replaced, may be performed on the side to be switched without overwriting or replacing, or may be coexistent so that either can be activated Alternatively, they may coexist so that a setting or a request and a response can be exchanged with any of them.

(2) Start: Start the component. Or, install and start the components. Alternatively, the execution area is changed from the file system area. The time may be designated to perform installation or activation, or installation and activation, or change from the file system area to the execution area. The downloaded and installed or made or built FASA application is put into the execution state. Note that the FASA application may be set to the execution state at a preset designated time.

(3) Replacement: Terminates or deletes a component being executed, or terminates and deletes, and activates another component. Or install another part and start. Alternatively, the part to be changed from the file system area to the execution area is replaced. It is also possible to specify the time, end or delete or end and delete, install or start another component, install and start another component, or replace the component to be the execution area. The running FASA application may be terminated and an application of a different version number or the like may be executed. It should be noted that FASA applications having different, for example, different version numbers or different functions, may be executed at a preset designated time. In the case of having a plurality of functions, at least one of the input and the output may be discarded without terminating the FASA application. When overwriting, the procedures of the above operations (1) to (3) may be performed simultaneously. Any of the coexisting devices may be active, or a setting or request and response may be exchanged with any of the coexisting devices.

(4) Stop: Stops the component being executed. Alternatively, stop the running component and delete it. It is also possible to specify the time and end or delete the part being executed or end and delete. The running FASA application may be stopped.

(5) Delete: Delete (uninstall) a component from the device (communication device 51). For example, the device (the communication device 51) deletes or uninstalls and deletes the FASA application (and related) file from the device itself. The above procedures (4) and (5) may be performed simultaneously.

(6) Status display: The type, version number, execution status, etc. of the component are displayed. At least one of the type, function, version number, and execution status of the FASA application may be displayed.

(7) Log recording: Logs such as addition, activation, replacement, stop, and deletion of parts are recorded. It may be filed. A log of addition / replacement / deletion of the FASA application may be recorded and filed.

(8) Capacity display: Used capacity and free capacity of both devices in the communication device 51 as the device 2 for storing components are displayed.

(Embodiment 1-1)
In Embodiment 1-1, a configuration of a communication device configuring a communication system used for the TWDM-PON will be described. The communication device described in the embodiment 1-1 is used as the device 2 shown in FIG. 1 or the communication device 51 shown in FIG. Hereinafter, first to sixth examples will be described as examples of the architecture of the communication device. The architecture of the communication device configuring the communication system may be an architecture other than the first to sixth examples described below. For example, the software unit of the communication device in the first to sixth examples of the architecture may be a hardware unit.

(First example of architecture)
FIG. 3 is a diagram illustrating a first example of the architecture of the communication device. In the first example of the architecture, the communication device includes a non-generic device-dependent unit 110 whose operation depends on the device, a middleware unit 120 that conceals differences between hardware and software of the device-dependent unit 110, and a device whose operation depends on the device. And a general-purpose device-independent application unit 130 that does not perform the operation. Therefore, the device-dependent unit 110 (vendor-dependent unit) is a functional unit that depends on the standard that the device of the communication device conforms to and the vendor of the device. In other words, the device-dependent unit 110 has low compatibility with other communication devices, and cannot be used as it is for a newly manufactured communication device (particularly, a device that conforms to a different standard or vendor). The device dependent unit 110 executes one or more functions provided in the network device.

  The device-independent application unit 130 is a functional unit that does not depend on a standard or a manufacturer of the device to which the device of the communication device conforms. In other words, the device-independent application unit 130 has 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 vendor). Specific examples of the application provided in the device-independent application unit 130 include an application that performs a setting process in a network device, an application that performs a setting change process, and an application that performs an algorithm process.

  The middleware unit 120 and the device independent application unit 130 are connected via the device independent API 21. The device-independent API 21 is an input / output IF that does not depend on the device.

  The device-dependent unit 110 includes, for example, a hardware unit 111 (PHY), a hardware unit 112 (MAC), a software unit 113, and an OAM (Operation Administration and Maintenance) unit 114. The hardware unit 111 (PHY), the hardware unit 112 (MAC), the software unit 113, the OAM unit 114, and the middleware unit 120 are connected via the device-dependent API. The device-dependent API 23 is an input / output IF that depends on the device. The device dependent unit 110 further includes an NE (Network Element) management / control unit 115. The NE management / control unit 115 and the middleware unit 120 are connected via the device-dependent API 25. The device-dependent API 25 is an input / output IF that depends on the device.

  What kind of function is used as the device-dependent unit 110 or the device-independent application unit 130 is determined by a limitation derived from processing for realizing the middleware unit 120 or the device-independent application unit 130, for example, due to processing capability of software. In addition to the restrictions, the update frequency may be determined according to the update frequency of the function or the importance of the extended function. Accordingly, the communication device can easily and flexibly and quickly add an extended function unit (unique function unit) by the device-independent application unit 130, and can provide a communication service in a timely manner.

  For example, priority is given to a function with a high update frequency such as priority processing of a main signal or DBA (Dynamic Bandwidth Assignment) for improving line use efficiency or a function that contributes to communication service differentiation, and is independent of the device dependent unit 110 or device independent. The application unit 130 may be determined. Furthermore, the device-independent application unit 130 may be used because the difference between the standards, generations, methods, systems, device types, and / or manufacturing vendors is small.

  Even if it is not optimal for at least one of the standard, generation, method, system, device type, and vendor of the manufacturer, any of the functions of the standard, generation, method, system, device type, or manufacturer of the vendor In order to generalize, a common IF for executing a function may be used. The common IF may include IFs and parameters that are not used in any of the standard, the generation, the system, the system, the device type, and the manufacturing vendor to which the device-dependent unit 110 conforms.

May be provided.

  The device dependent unit 110 illustrated in FIG. 3 includes a hardware unit 111 (PHY), a hardware unit 112 (MAC), and a software unit 113. The hardware unit 111 (PHY) executes a process from the physical layer to processes related to optical transmission and reception (PHYsical sublayer process). The hardware unit 112 (MAC) executes a MAC (Media Access Control) process. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) depend on a standard or a manufacturing vendor to which the hardware unit 111 conforms. The software unit 113 executes a device-dependent driver, firmware, application, and the like.

  The hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device dependent unit 110 may include a general-purpose server, a layer 2 switch, and the like in addition to the above. The device dependent unit 110 may not include the hardware unit 112 (MAC). The device dependent unit 110 may not include a part of the hardware unit 111 (PHY). For example, the device-dependent unit 110 does not include low-level signal processing such as modulation / demodulation signal processing, forward error correction (FEC, Forward Error Correction), codec processing, and encryption processing, and may include only light-related functions. Good. The device-dependent unit 110 does not need to include a PCS (Physical Coding Sublayer) which is a part for encoding data. The device dependent unit 110 does not need to include a PMA (Physical Medium Attachment) for serializing data and a PCS. The device dependent unit 110 does not need to include a PMD connected to a physical medium. When the middleware unit 120 directly drives, controls, operates, or manages the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device dependent unit 110 without the intervention of the software unit 113, The software unit 113 may not be provided.

  The device-independent application unit 130 includes, for example, the extended function units 131-1 to 131-3 (in FIG. 3, the extended function A, the extended function B, and the extended function C), the basic function unit 132, and the management / control agent unit. 133. The management / control agent unit 133 exchanges data with an EMS (Element Management System) 140.

  In the figure, the EMS 140 and the external device 160 are connected to the device-independent application unit 130 via the middleware unit 120, but the EMS 140 and the external device 160 are not necessarily connected to the device-independent application unit 130 via the middleware unit 120. You don't have to. The EMS 140 and the external device 160 may be appropriately connected to the middleware unit 120 as needed, or may be directly connected to the device-independent application unit 130. The expression “connection via the middleware unit 120” is an expression from the viewpoint of the device-independent application unit 130. Actually, device-independent applications are connected via the middleware unit 120 after connection by hardware.

  Hereinafter, items common to the extended function units 131-1 to 131-3 will be referred to as “extended function unit 131” with some reference numerals omitted. The EMS 140 is, for example, an NE controller. Note that the device-independent application unit 130 may not include any of the extended function unit 131, the basic function unit 132, and the management / control agent unit 133, or the management / control agent unit 133 , Or the management / control agent unit 133 may be included in the basic function unit 132 or the middleware unit 120.

  The device-independent application unit 130 may further include a configuration other than the extension function unit 131, the basic function unit 132, and the management / control agent unit 133. For example, when the extension function unit 131 is unnecessary, the device-independent application unit 130 may not include the extension function unit 131. Further, the device-independent application unit 130 may include one or more extended function units 131.

  It is preferable that the extension function unit 131 can be independently added, deleted, replaced, or changed without unnecessarily affecting other functions. For example, the extended function unit 131 may be appropriately added, deleted, replaced, or changed when the extended function unit 131 that executes, for example, a multicast service or power saving is required in accordance with a service request. .

  The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a function unit lower than the middleware unit 120. When the extension function unit 131 includes the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132. When a function unit lower than the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132. When the extension function unit 131 includes the basic function unit 132 and a function unit lower than the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132.

  The management / control agent unit 133 does not need to input / output to / from the EMS 140 when receiving the communication from the EMS 140 and automatically performing the setting according to the predetermined setting. Furthermore, when the management / control agent unit 133 does not have the management setting function and the other device independent application unit 130, the basic function unit 132, and the device dependent unit 110 have the management setting function, the device independent application unit 130 The management / control agent unit 133 need not be provided.

  The EMS 140 and the device-independent application unit 130 may directly input and output information. Further, the device dependent unit 110 may be replaced by an NE management / control unit 115 and a device dependent application unit 150 (see FIG. 4 described later and FIG. 6 described below) of a functional unit below the NE management / control unit 115. Good.

  The management / control agent unit 133 does not need to input and output information to and from the EMS 140 when performing automatic setting according to a predetermined setting. Further, when the management / control agent unit 133 does not have the management setting function and the other device independent application unit 130, the basic function unit 132, and the device dependent unit 110 have the management setting function, the device independent application unit 130 The control agent unit 133 need not be provided. The EMS 140 and the device-independent application unit 130 may directly input and output information.

An example of input and output between the device-independent application unit 130 and the device-dependent unit 110 is as follows.
For example, the DBA application unit and the protection application unit mutually input and output information with an embedded OAM engine of the TC layer. A DWBA (Dynamic Wavelength and Bandwidth Assignment) application and an ONU registration authentication application unit mutually input and output information with the PLOAM engine of the TC layer. The power saving application unit inputs and outputs information to and from the OMCI and the L2 main signal processing function unit (L2 function unit). An MLD (Multicast Listener Discover) proxy application unit inputs and outputs information to and from the L2 function unit. The low-speed monitoring application (OMCI) inputs and outputs information to and from the OMCI. The OMCI and L2 functional units operate an XGEM Encapsulation Method Framer and encryption. Here, the DWBA and the DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit of a maintenance operation function, and inputs and outputs information to and from the EMS 140 which is an NE controller or the like for the NE management / control unit 115.

  The implementation of the device-independent application unit 130 may have a priority. For example, the management / control agent unit 133 has the highest priority. The second and lower priorities are, for example, a DBA application, a DWBA application, a power saving application, an ONU registration authentication application, an MLD proxy application, a protection application, and a low-speed monitoring application (OMCI).

  The device-independent application unit 130 includes a device vendor, a method, a device type, and a device generation, for example, an ITU-TG. TWDM-PON based on ITU-T G.989 series XG-PON conforming to the 987 series and ITU-TG. G-PON based on ITU-T G.984 series. It is an application that operates without depending on any of the B (Broadband) PON based on the 983 series. The device-independent application unit 130 is a device vendor, a method, a device type, and a device generation, for example, a difference between a 10GE-PON conforming to IEEE802.3av or IEEE1904.1 and a GE-PON conforming to IEEE802.3ah. It is an application that works without depending on it.

  Only applications for driving functions provided for some vendors, methods, types, and generations, and devices for some vendors, methods, types, and generations via the device-independent API 21 as applications of the extended function unit 131 It may include an application that drives a function provided for.

  The management / control agent unit 133 inputs and outputs with the EMS 140 and the middleware unit 120. The middleware unit 120 inputs and outputs NE management information and control information to and from the NE management / control unit 115. The NE management / control unit 115 may directly transmit and receive the NE management information and control information to and from the EMS 140 without passing through the middleware unit 120, or may transmit the NE management information and control information via the management / control agent unit 133. You may send and receive.

  The middleware unit 120 inputs and outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs and outputs information via the device-dependent API 23 to and from the OAM unit 114, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) of the device-dependent unit 110. The middleware unit 120 outputs the input information as it is or in a predetermined format. For example, if the output destination is each unit of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each unit of the device-independent API 21. If the output destination is the OAM unit 114, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) of the device-dependent unit 110, the middleware unit 120 sends the device-dependent API The information is transmitted to an output destination after being converted into a format or subjected to predetermined processing after termination.

  At the time of input, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, collects and supplements it via another device-independent API 21 or another device-dependent API 23. desirable. In addition, when inputting to the middleware unit 120, it may be broadcast or multicast to broadcast to related applications and the like.

  In FIG. 3, the middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit. When a plurality of processors are included in the hardware of the device-dependent unit 110, the middleware unit 120 may perform input / output using inter-processor communication or the like across processors and hardware. The device-independent application units 130 and the device-independent application units 130 may be arranged in a user space on a single processor as an execution program such as a DLL (Dynamic Link Library), or may be arranged on a plurality of processors. It may be arranged in the user space.

The device-independent application unit 130 may be arranged in the kernel space after securing an input / output IF such as an API, or may be arranged together with the middleware unit 120 having an IF that can be independently replaced with firmware or the like. Alternatively, it may be compiled into firmware or the like and recompiled. The user space and the kernel space may be arbitrarily combined for each device-independent application unit 130.
The device-independent application unit 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 may be selected by switching, the processing may be performed in cooperation with each other, or the actual processing may be performed by only one of them. The same applies to the software of the device-dependent unit 110.

  Desirably, as high-speed processing is required as in main signal processing, DBA processing, or low-layer signal processing, there is a trade-off between scalability and immediacy of replacement, but high-speed processing with little overhead is expected. It is desirable to incorporate it into kernel space or firmware. The processor in which the device-dependent application unit 150 (see FIG. 4 to be described later and FIG. 6 to be described later) is arranged is also considered to be effective from the viewpoint of the restriction on the bus and speed due to the inter-processor communication and the influence on other programs due to the occupation of the communication path. It is desirable to arrange in a user space, a kernel space, or firmware of a processor that performs processing or a processor in the vicinity thereof. However, in order to reduce the capacity of the processor performing the actual processing or the processor in the vicinity thereof, the communication cost by the inter-processor communication increases, but the processing may be performed by a remote processor.

  It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance, assuming the extended function unit 131 to be added. However, it is necessary to prevent the device-dependent API 23 and other device-independent application units 130 from being modified. They may be added or deleted accordingly.

  In this example, the softened area is the basic function unit 132, the management / control agent unit 133, the extended function unit 131, and the middleware unit 120. However, the softened area is a service adaptation (encryption, fragment processing, GEM Frame / XGEM framing, PHY adaptation FEC, scrambling, synchronization block generation / extraction, GTC (GPON Transmission Convergences) framing, PHY framing, SP conversion, and coding method may also be targets. A description will be given of an example of implementation and a function deployment corresponding to a hardware unit.The function deployment includes, for example, a software function in a network device or an external server, and the same applies to other examples.

If the device-dependent application unit 150 has been automatically set according to a predetermined setting without receiving communication from the EMS 140 and can acquire management and control information from the EMS 140 via the middleware unit 120, The independent application unit 130 may not include the management / control agent unit 133.

  The device-independent application unit 130 inputs information at least between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 or the software unit 113 via the middleware unit 120. Output. The device-independent application units 130 mutually input and output via the middleware unit 120 as necessary. In particular, when the device-independent application unit 130 performs control or management according to information input / output to / from the EMS 140, the device-independent application unit 130 exchanges information with the management / control agent unit 133 that receives communication from the EMS 140.

(Third example of architecture)
FIG. 5 is a diagram illustrating a third example of the architecture of the communication device. In FIG. 5, instead of the middleware unit 120 described in the first example of the architecture shown in FIG. 3, the basic function unit 132 includes a hardware unit 111 (PHY) and a hardware unit 112 (MAC), and an extended function unit 131.

It need not be connected to the unit 130. The EMS 140 and the external device 160 may be appropriately connected to the middleware unit 120 as needed, or may be directly connected to the device-independent application unit 130. The expression “connection via the middleware unit 120” is an expression from the viewpoint of the device-independent application unit 130. Actually, device-independent applications are connected via the middleware unit 120 after connection by hardware.

  Compared to the first example of the architecture, the third example is that the middleware unit 120 including the device-dependent APIs 23 and 25 is provided for each device that differs in at least one of the compliant standard, generation, method, system, device type, and manufacturing vendor.

And a software unit 113 such as firmware for driving the driver. The driver or the like hides the difference between the device dependent units 110.

  The device-independent application unit 130 includes an extended function unit 131 and a basic function unit 132. The basic function unit 132 is controlled by the device-independent API 27 (porting IF) via a hardware unit 111 (PHY) and a driver that conceals the difference between the hardware unit 112 (MAC) and the device-dependent software unit 113. Connect to the dependency unit 110. The device-independent application unit 130 communicates with the hardware unit 111 (PHY) and the hardware unit 112 (MAC) via a driver that conceals the difference between the hardware unit 112 (MAC) and the device-dependent software unit 113. Data is input and output between the hardware unit 112 (MAC) and the device-dependent software unit 113.

If there is, the information is input after the input format is converted into the device-independent API 22 format or after termination and predetermined processing. At the time of input, the basic function unit 132 deletes unnecessary input information at each input destination, and collects and supplements, via the other device-independent APIs 22 and 27, if there is insufficient information. It is desirable. However, the basic function unit 132 may broadcast or multicast the input to the input destination and broadcast it to a related application or the like.

  The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 and a basic function unit 132. The device-independent application unit 130 may not include any of the extended function unit 131 and the basic function unit 132. The device-independent application unit 130 may further include a functional unit other than the extended function unit 131 and the basic function unit 132. For example, when the extension function unit 131 is unnecessary, the device-independent application unit 130 may not include the extension function unit 131.

  It is preferable that the extension function unit 131 can be independently added or deleted without affecting other functions. For example, when the extended function unit 131 is used for the multicast service and power saving corresponding to a service request, for example, the extended function unit 131 is appropriately added when it becomes necessary, and is appropriately deleted when it becomes unnecessary. However, replacement or change may be made according to the change.

  The device-independent API 22 is desirably provided in the basic function unit 132 in advance, assuming an extended function unit 131 to be added later. However, if necessary, the device-independent API 22, the device-independent API 27, and other device-independent APIs may be used. It may be added or deleted in such a manner that the modification of the dependent application unit 130 is suppressed.

The device-dependent unit 110 includes a hardware unit 111 (PHY) and a hardware unit 112 (MAC), and a hardware unit 111 (PHY) and a hardware unit 112 (MAC) that depend on a compliant standard or a device manufacturing vendor. It has a software unit 113 such as a driver and firmware to be driven, and a device-dependent application unit 150 that drives at least a part of the device-dependent unit 110. The device-independent application unit 130 is provided via a driver that conceals a difference between the porting IF, the hardware unit 111 (PHY), and the hardware unit 112 (MAC) and device-dependent software, or through a porting IF and the device-dependent application. This is a general-purpose device-independent application that executes device-independent processing via the unit 150. The basic function unit 132 in the device independent application unit 130 and the device dependent application unit 150 in the device dependent unit 110 are connected via the device independent API 27. The device-dependent application unit 150 and other functional units of the device-dependent unit 110 are connected via the device-dependent API 24.

  As for the basic function unit 132 in the device-independent application unit 130, the basic function unit 132 performs input / output with the hardware and the extended function unit 131 instead of the middleware unit 120. The basic function unit 132 may include a management / control agent unit 133 (see FIGS. 3 and 4) that receives communication from the EMS 140, or includes the management / control agent unit 133 as the extended function unit 131. You may.

  The basic function unit 132 inputs and outputs with the extension function unit 131 via the device-independent API 22 (expansion IF), and the OAM unit, the driver, the firmware, the hardware unit 111 (PHY), and the hardware unit of the device dependence unit 110 112 (MAC) and a device-independent API 27 (porting interface), which input / output via the device-independent API 27 (porting IF) and conceal differences between the device-dependent units 110, IF).

  The basic function unit 132 receives the input as it is or in a predetermined format, similarly to the middleware unit 120 shown in FIG. Similarly to the third example of the architecture, the basic function unit 132 may include a management / control agent unit 133 that receives communication from the EMS 140, or the management / control agent unit 133 as the extended function unit 131. May be provided.

  The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 and a basic function unit 132. The device-independent application unit 130 may not include any of the extended function unit 131 and the basic function unit 132, as in the third example of the architecture. The device-independent application unit 130 may further include a functional unit other than the extended function unit 131 and the basic function unit 132, as in the third example of the architecture.

  As in the third example of the architecture, it is preferable that the extension function unit 131 can be added, deleted, replaced, or changed independently of each other without affecting other functions. A part of the basic function unit 132 may be replaced by the device-dependent application unit 150. Although the device-dependent application unit 150 directly inputs and outputs information from the basic function unit 132, even if the information is input and output to and from the EMS 140 without passing through the basic function unit 132 as it is or after a predetermined conversion. Good.

  As in the first example of the architecture shown in FIG. 3, the device-independent APIs 22 and 27 are desirably provided in advance in the basic function unit 132 in consideration of an extended function unit 131 to be added later. The device-independent API 27, the other device-independent application unit 130, the device-dependent application unit 150, or the device-dependent API 24 may be added or deleted as needed in a manner that suppresses modification.

(Fifth example of architecture)
The upper right diagram of FIG. 7 is a diagram illustrating a fifth example of the architecture. The lower right part of FIG. 7 corresponds to first to fourth examples of the architecture. FIG. 1 shows a case where the communication device is an OLT. The fifth example of the architecture is a function cloud in which OLT functions are implemented (clouded) on external hardware, and existing / commercial OLT hardware is used to prepare / add functions according to the service. It is suitable when the approach of conversion is performed.

  In this example, the communication device includes existing / commercial hardware and external hardware. For example, existing / commercial hardware is a non-general-purpose device-dependent unit 110 that depends on a device, a middleware unit 121 that conceals differences between hardware and software on external hardware, and a general-purpose device that does not depend on the device. And a device independent application section 130. Therefore, the device-dependent unit (vendor-dependent unit) below the middleware in the figure is a functional unit that depends on the standard that the device of the communication device conforms to and the vendor of the device. The device-independent application unit 130 is a functional unit that does not depend on a standard or a manufacturer of the device to which the device of the communication device conforms.

  The middleware unit 121 and the device-independent application unit 130 are connected via a device-independent API that is an input / output IF that does not depend on the device. For example, the software unit, the OAM, the hardware unit (PHY) and the hardware unit (MAC) of the device-dependent unit 110, and the middleware unit 121 on the external hardware are device-dependent input / output IFs depending on the device. It is connected via the API and the inter-device connection between existing / commercial hardware and external hardware.

  In this architecture, the device-independent application unit 130 can easily and flexibly add an extended function unit (unique function unit), and can provide a communication service in a timely manner. Here, the device-dependent unit 110 may be a maintenance operation, access control, physical layer processing, or optical module shown in FIG. 7, depending on the configuration of the device itself.

  For example, the device-dependent unit 110 or the device-independent application unit 130 may give priority to a function with a high update frequency such as a priority processing of a main signal or a DBA that improves line use efficiency or a function that contributes to communication service differentiation. You may decide. Furthermore, the device-independent application unit 130 may be used because the difference between the standards, generations, methods, systems, device types, and / or manufacturing vendors is small.

  Even if it is not optimal for at least one of the standard, generation, method, system, device type, and vendor of the manufacturer, any of the functions of the standard, generation, method, system, device type, or manufacturer of the vendor In order to generalize, a common IF for executing a function may be used. The common IF may include IFs and parameters that are not used in any of the standard, the generation, the system, the system, the device type, and the manufacturing vendor to which the device-dependent unit 110 conforms.

  A conversion function unit that converts an IF, a parameter, and the like to correspond to the device-dependent unit 110 to at least one of the middleware unit 121, the driver of the device-dependent unit 110, and the device-dependent application unit 150 (vendor-dependent application unit). Alternatively, a function unit for automatically setting in response to an insufficient IF, parameter, or the like may be further provided.

  The device dependent unit 110 includes a hardware unit and a software unit. The software unit executes a device-dependent driver, firmware, application, and the like.

  The device-dependent unit 110 may not include a PMD and a MAC connected to a physical medium, a PMA that serializes data, and a part of a PCS or a PHY that encodes data. For example, only light-related functions may be provided without low-level signal processing such as modulation / demodulation signal processing, forward error correction (FEC), codec processing, and encryption processing.

  The device-independent application unit 130 is, for example, a management / control agent unit 133 that acquires data from EMS, extended function units 131-1 to 131-3, and a basic function unit 132. Hereinafter, items common to the extended function units 131-1 to 131-3 will be referred to as “extended function unit 131” with some reference numerals omitted. The EMS is, for example, a controller that controls a network element. The device-independent application unit 130 may not include any of the management / control agent unit 133, the extended function unit 131, and the basic function unit 132.

  The device-independent application unit 130 may further include a configuration other than the management / control agent unit 133, the extended function unit 131, and the basic function unit 132. For example, when the extension function unit 131 is unnecessary, the device-independent application unit 130 may not include the extension function unit 131. Further, the device-independent application unit 130 may include one or more extended function units 131.

  It is preferable that the extension function unit 131 can be independently added, deleted, replaced, or changed without unnecessarily affecting other functions. For example, the extended function unit 131 may be appropriately added, deleted, replaced, or changed when the extended function unit 131 that executes, for example, a multicast service or power saving is required in accordance with a service request. .

  The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a function unit lower than the middleware unit 121. When the extension function unit 131 includes the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132. When a function unit lower than the middleware unit 121 replaces the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132. When the extension function unit 131 includes the basic function unit 132 and a function unit lower than the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 may not include the basic function unit 132.

  The management / control agent unit 133 does not need to input / output to / from the EMS 140 when receiving the communication from the EMS 140 and automatically performing the setting according to the predetermined setting. Furthermore, when the management / control agent unit 133 does not have the management setting function and the other device independent application unit 130, the basic function unit 132, and the device dependent unit 110 have the management setting function, the device independent application unit 130 The management / control agent unit 133 need not be provided.

  The EMS 140 and the device-independent application unit 130 may directly input and output information. Further, the device dependent unit 110 may not include the NE management / control unit 115 and the IF of the NE management / control unit 115.

  The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a lower function unit of the middleware unit 120. When the extension function unit 131 includes the basic function unit 132, when the lower function unit of the middleware unit 120 substitutes for the basic function unit 132, or when they are a combination thereof, the device-independent application unit 130 132 may not be included. Further, a part of the basic function unit 132 may be replaced by the device-dependent application unit 150 which is a lower function unit of the middleware unit 120.

  The management / control agent unit 133 does not need to input and output information to and from the EMS 140 when performing automatic setting according to a predetermined setting. Further, when the management / control agent unit 133 does not have the management setting function and the other device independent application unit 130, the basic function unit 132, and the device dependent unit 110 have the management setting function, the device independent application unit 130 The control agent unit 133 need not be provided. The EMS 140 and the device-independent application unit 130 may directly input and output information.

  An example of input and output between the device-independent application unit 130 and the device-dependent unit 110 is as follows. For example, the DBA application unit and the protection application unit mutually input and output information with the embedded OAM engine of the TC layer. The DWBA application and the ONU registration authentication application unit mutually input and output information with the PLOAM engine of the TC layer. The power saving application unit inputs and outputs information to and from the OMCI and the L2 main signal processing function unit (L2 function unit). The MLD proxy application unit exchanges information with the L2 function unit. The low-speed monitoring application (OMCI) inputs and outputs information to and from the OMCI. The OMCI and L2 functions operate the XGEM framer and encryption. Here, the DWBA and the DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit of a maintenance operation function, and inputs and outputs information to and from the EMS 140 which is an NE controller or the like for the NE management / control unit 115.

  The device-independent application unit 130 includes a device vendor, a method, a device type, and a device generation, for example, an ITU-TG. TWDM-PON based on ITU-T G.989 series XG-PON conforming to the 987 series and ITU-TG. G-PON based on ITU-T G.984 series. It is an application that operates without depending on any of the 983 series compliant BPON. The device-independent application unit 130 is a device vendor, a method, a device type, and a device generation, for example, a difference between a 10GE-PON conforming to IEEE802.3av or IEEE1904.1 and a GE-PON conforming to IEEE802.3ah. It is an application that works without depending on it.

  Only applications for driving functions provided for some vendors, methods, types, and generations, and devices for some vendors, methods, types, and generations via the device-independent API 21 as applications of the extended function unit 131 It may include an application that drives a function provided for.

  The management / control agent unit 133 inputs and outputs with the EMS 140 and the middleware unit 120. The middleware unit 120 inputs and outputs NE management information and control information to and from the NE management / control unit 115. The NE management / control unit 115 may directly transmit and receive the NE management information and control information to and from the EMS 140 without passing through the middleware unit 120, or may transmit the NE management information and control information via the management / control agent unit 133. You may send and receive.

  The middleware unit 120 inputs and outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs and outputs information via the device-dependent API 23 to and from the OAM unit 114, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) of the device-dependent unit 110. The middleware unit 120 outputs the input information as it is or in a predetermined format. For example, if the output destination is each unit of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each unit of the device-independent API 21. If the output destination is the OAM unit 114, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) of the device-dependent unit 110, the middleware unit 120 sends the device-dependent API The information is transmitted to an output destination after being converted into a format or subjected to predetermined processing after termination.

  At the time of input, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, collects and supplements it via another device-independent API 21 or another device-dependent API 23. desirable. In addition, when inputting to the middleware unit 120, it may be broadcast or multicast to broadcast to related applications and the like.

  Although the middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit, each unit may be composed of a plurality of units. When a plurality of processors are included in the hardware of the device-dependent unit 110, the middleware unit 120 may perform input / output using inter-processor communication or the like across processors and hardware. The device-independent application units 130 and the device-independent application units 130 may be arranged in a user space on a single processor as an execution program such as a DLL, or may be arranged in a user space on a plurality of processors. May be.

  The device-independent application unit 130 may be arranged in the kernel space after securing an input / output IF such as an API, or may be arranged together with the middleware unit 120 having an IF that can be independently replaced with firmware or the like. Alternatively, it may be compiled into firmware or the like and recompiled. The user space and the kernel space may be arbitrarily combined for each device-independent application unit 130.

  The device-independent application unit 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 may be selected by switching, the processing may be performed in cooperation with each other, or the actual processing may be performed by only one of them. The same applies to the software of the device-dependent unit 110.

  Desirably, as high-speed processing is required as in main signal processing, DBA processing, or low-layer signal processing, there is a trade-off between scalability and immediacy of replacement, but high-speed processing with little overhead is expected. It is desirable to incorporate it into kernel space or firmware. The processor in which the device-dependent application unit 150 is arranged also has a user space for a processor that performs actual processing or a processor in the vicinity of the processor that performs actual processing from the viewpoint of restrictions on buses and speeds due to inter-processor communication, occupation of a communication path, and other effects on other programs. It is desirable to place it on the kernel space or firmware. However, in order to reduce the capacity of the processor performing the actual processing or the processor in the vicinity thereof, the communication cost by the inter-processor communication increases, but the processing may be performed by a remote processor.

  It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance, assuming the extended function unit 131 to be added. However, it is necessary to prevent the device-dependent API 23 and other device-independent application units 130 from being modified. They may be added or deleted accordingly.

The sixth example of the architecture includes a hardware unit 111 (PHY) and a hardware unit 112 (MAC) depending on a standard or a device manufacturing vendor based on the device dependent unit 110, and a hardware unit 111 (PHY) and a hardware. A software unit 113 such as driver firmware for driving the unit 112 (MAC) and a device dependent application unit 150 for driving at least a part of the device dependent unit 110 are provided.

  The device-dependent application unit 150 and the device-dependent unit 110 are connected via the device-dependent API 24. The device-dependent application unit 150 may include a management / control agent unit 133 that receives communication from the EMS 140. The device-dependent API 24 may be added or deleted as necessary in a form that suppresses modification of the device-dependent application unit 150 and the device-dependent API 24.

  The configuration of the communication device shown in the first to sixth examples of the architecture of the communication device is described on the premise of the OLT of the PON conforming to the ITU-T recommendation such as the TWDM-PON. The PON may be either an OLT or an ONU of a PON conforming to the ITU-T recommendations other than the TWDM-PON, or may be a PON conforming to the IEEE standards such as GE-PON and 10GE-PON. The same applies if the layer or PMD layer is read as a corresponding layer.

  Hereinafter, the TWDM-PON includes a PON multicast function, a power saving control function, a frequency / time synchronization function, a protection function, a maintenance operation function, an L2 main signal processing function, a PON access control function, and a PON main signal. An example in which the processing function is mainly provided will be described.

For example, in addition to the configuration in which the transmitting and receiving units 11 for transmitting and receiving optical signals of different wavelengths (λA to λN) are connected to the same switch unit 12, the transmitting and receiving unit 11 for transmitting and receiving optical signals of the same wavelength is the same switch. The transmitting and receiving units 11 of at least some of the transmitting and receiving units 11 for transmitting and receiving optical signals of different wavelengths (λA to λN) may be connected to the same switch unit 12. Alternatively, some or all of the transmission / reception units 11 may be the transmission / reception units 11 that perform only transmission or only reception.

  A communication device such as the OLT may include the control unit 14 from the transmission / reception unit 11 or may further include an external server 16 in addition to the above. Further, the OSU may be the transmission / reception unit 11, or may further include a switch unit 12 (SW) or a switch unit 13 (SW).

A component may be placed on the EMS, a component may be placed on a Virtual OLT (virtual OLT) on the EMS, or a component may be placed in parallel with the Virtual OLT on the EMS. In the approach of ONOS and the like, there is no mechanism for providing a recommendation proposal due to the suitability as in the present application, so that it is effective even when a component is placed on the EMS.

Have been. 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 FASA application API middleware.

  The protection application is connected to PLOAM Engine and Embedded OAM Engine via FASA application API middleware. The power saving application is connected to OMCI and PLOAM Engine via FASA application API middleware. The ONU registration authentication application and the DWBA application are connected to PLOAM Engine via FASA application API middleware, and the DBA application is connected to Embedded OAM Engine via 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. Input from an external device is connected to the DBA application via FASA application API middleware. Note that these connections are examples, and an input from an external device may be connected to an application other than the DBA application, for example, a protection application or a DWBA application. Also, input from an external device may be IF-converted via an IF conversion application via FASA application API middleware, or connected to a DBA application or the like via a setting / management application via FASA application API middleware.

As an example of the function sharing, processing by an application except for the hardware Config may be performed, and processing by an application on the external server 16 in FIG. 8 may be performed without holding software and setting data in the ONU or the OLT. It can also be realized by unifying commands and defining sequences.

The processing that configures the maintenance operation function of the maintenance operation function unit 330 includes monitoring / control input / output (sleep instruction / reply, λ setting switching instruction / reply, etc.) that requires high speed. As means of this processing, a physical layer OAM (PLOAM: PHYsical Layer OAM) message and a bit indication (embedded OAM) in the header are used. These processes may be composed of basic processes such as PLOAM process, Embedded OAM process, communication with the power saving control function unit 360, communication with the protection function unit 380, and communication with the PON access control function unit 320.

The identification or distribution of the multicast stream, the MLD proxy / snooping, the ONU filter setting, and the inter-wavelength setting transition may be realized by a combination of basic processes. In addition, the order may be changed.

  In the description of the present application, MLD is exemplified as a multicast protocol, but the same applies to other protocols such as IGMP.

  In the main function of the PON multicast function unit 350, when processing of 10 Gbit / s / λ and 2.5 Gbit / s / λ is performed for each wavelength for identification / distribution, 10 Gbit / s / λ and 2.5 Gbit / s are respectively processed. If the stream processing of / λ or more processes a plurality of wavelengths, a plurality of wavelengths are obtained. Further, in the main function of the PON multicast function unit 350, it is required that the zapping performance (Zapping performance) (JOIN latency) conforms to a rule such as an average of 1.5 seconds or less as packet processing.

  As an example of the allocation of functions, the identification and distribution of the multicast (MC) stream can be performed by software if a CPU or the like having a high-speed processing capability is used, but hard + config is desirable. In addition, setting of the application system and ONU for the uplink is performed by the application because the frequency and the delay constraint are loose.

  FIG. 18 is a diagram illustrating an example of a functional configuration of the power saving control function unit 360.

  As an example of the function allocation, a power save (PS) application, or proxy processing may be performed by an application depending on a signal. The power saving control state transition management (driver section) requires a speed, but may be processed by an application. The traffic monitor can also be processed by the application only for the configuration (config).

  FIG. 19 is a diagram illustrating an example of a functional configuration of the frequency / time synchronization function unit 370. The OLT synchronizes its own real-time clock (RTC) with a higher-level device using SyncE (Synchronous Ethernet (registered trademark)) (for frequency synchronization) and IEEE 1588v2 (time synchronization). Further, using the OMCI, the ONU is notified of the correspondence between the PON superframe counter (SFC) and the absolute time (ToD: Time of Day) information. 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. In addition, the order may be changed.

  In this main function, frequency synchronization accuracy +/- 50 ppb (LTE FDD, same TDD), time synchronization accuracy +/- 1 to 1.5 microseconds (LTE TDD, small cell), +/- 1 microsecond (G. 987.3). As an example of the function allocation, the real-time clock itself is the device-dependent unit 110, and the time adjustment calculation for the higher-level device can be performed by an application (the device-dependent unit 110 can be used depending on the accuracy).

  FIG. 20 is a diagram illustrating an example of a functional configuration of the protection function unit 380. The processing that configures the protection function of the protection function unit 380 includes redundancy switching (CT, SW, NNI, CONT, PON (Type A, B, C)). 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. In addition, the order may be changed.

  In this main function, the forced switching is required to comply with a rule such as 50 milliseconds or less. As an example of the function allocation, processing by an application may be performed except for hardware switching trigger detection and switching processing such as failure detection. The case where an instruction is given to the EMS side when a switching trigger is detected without setting a redundant path in advance is device-dependent.

  The eight main functions may be provided as needed. 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 the other functions may be provided. You may. Also, the evaluation of the possibility of softwareization of each function is an example on the assumption that the processing capability of the OLT assumed in 2018 and the application of the soft switch is not assumed. It may be changed appropriately assuming the assumed processing capacity and application of the soft switch. The function may be software-enabled, or may not be software-enabled. The internal configuration of each function may be another configuration as long as the same function can be realized.

  The algorithms included in the eight main functions are the main software areas. The function used as the software area is referred to as a device-independent application unit 130 on the device-independent APIs 21 and 22. For example, algorithms in the ONU registration or authentication function, the DWBA function, the setting / management / monitoring control function, and the power saving control function that contribute to the differentiation service are handled as the extended function unit 131 in the device independent application unit 130. The MLD proxy application includes a multicast function.

  The extension function unit 131 is set as the extension function unit 131 in accordance with the degree of importance of the update frequency of the function or the realization of the original specification or the like among the applications. Those whose update frequency is low or whose demand for realization such as original specifications is low are middleware units 120 other than the basic function unit 132 and the device-independent application unit 130, device-dependent software, the hardware unit 111 (PHY), and the hardware unit 112 ( MAC). In particular, it is preferable that functions having restrictions due to the processing capability of software remain as the hardware unit 111 (PHY) and the hardware unit 112 (MAC). For example, priority signal processing for main signals and DBA for improving line use efficiency, etc., functions that contribute to high frequency of renewal or service differentiation, and management that is closely related to the business flow of operators and requires unique specifications for each operator The control function is referred to as an extended function unit 131.

  FIG. 21 is a diagram illustrating an example of details of the architecture of the communication device. The embedded OAM engine 114a (Embedded OAM Engine) is connected to the DBA application unit and the protection application unit via the middleware unit 120. The PLOAM engine 114b is connected to the DWBA application, ONU registration authentication, high-speed monitoring application, power saving application, and protection application via the middleware unit 120.

The NE control 115b is connected to a low-speed monitoring application (EMS-IF).

  FIG. 22 is a diagram illustrating a flow of signals / information between functional units in the communication device. FIG. 2 shows the flow of signals / information between the functional units in the communication device, focusing on In / Out of the OLT. As shown in the figure, the OLT as a communication device is composed of an API lower processing entity (FASA platform) and an application (FASA application).

The API lower processing entity is an MPCP / DBA processing entity whose OLT input / output target is a transmission instruction and reception notification for MPCP transmission / reception, an OAM processing entity whose OLT input / output target is an OAM transmission / reception, and an OLT input / output target is an ONU authentication transmission / reception. A certain ONU authentication processing entity, an MLD / IGMP processing entity whose OLT input / output target is MLD / IGMP transmission / reception, another protocol processing entity whose OLT input / output target is another protocol transmission / reception, and main signal processing such as OLT input / output of bridge / encryption The main signal setting processing entity, which is the setting, reference, and status acquisition, and the device management processing entity whose OLT input / output target is an OLT hardware, IF, OS, or the like. Here, it is desirable that the transmission instruction and the reception notification for the MPCP transmission / reception be something like send_frame (* raw_frame);
In the drawing, DBA, ONU management, line management, multicast, EtherOAM, redundancy, device management, alarm management, Netconf agent, and application management are illustrated as applications.

  The OLT In / Out is roughly classified into three types: input / output to the ONU, setting / notification to the OLT itself, and input / output to the EMS. From the viewpoint of the application on the upper side of the API, the processing for the API lower side is (a) easier (convenient) and (b) common (for a plurality of types) compared to processing such as direct driver tapping. , (C) It is desirable to have a processing entity that performs processing conveniently.

  The function allocation of the API lower processing entity is exemplified below. The app has a corresponding process. The function allocation between the API lower processing entity and the application may be any of the following or other, and may be different for each processing situation.

(0) Message through: The message is passed between the API upper side and the ONU / upper NW.

(1) Framing: The message is provided in the upper part of the API by removing the frame and decomposing or processing the message as necessary. Information is passed from the upper part of the API to the lower part of the API. The API lower processing entity performs framing. Since the API largely depends on each protocol, the API may be included in the device-dependent application unit. It is desirable that fixed parameters (such as a type value) are set from the upper part of the API at the time of initialization or the like and retained. The setting parameters are returned in response to the reference from the upper part of the API.

(2) Automatic response: The processing entity is responsible for message transmission / reception that does not require judgment, such as periodic transmission and fixed response. It is desirable that operation settings be made in advance from the top of the API. For example, a response cycle. The result is notified only when notification to the upper part of the API is necessary.

(3) Autonomous judgment: Processing involving judgment is also handled by the processing entity. The policy is set in advance from the top of the API.

  Although this drawing is described in conformity with IEEE-compliant 10 GEPON, the same applies to devices conforming to ITU-T or other standards as long as the corresponding functions and processes are re-read. Further, the functions and the actual processing are merely examples, and may be appropriately added, deleted, replaced, or changed according to conditions.

  FIG. 23 is a diagram illustrating an example of an application executed by the communication device. The processing of the CPU is classified into three groups. The three groups are a CPU for Cont, a CPU for OSU, and a CPU for SW. The processing of the CPU for the Cont direction is processing for executing a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS-IF), and a setting / management application. The processing of the CPU for SW is a processing for executing the MLD proxy application. The processing of the CPU for the OSU is a processing for executing a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWBA application, and an ONU registration authentication application. The device setting IF may be a part of the EMS-IF, or may be equivalent to the device-dependent API 25.

  This is an example in which each application is processed by the CPU on the CPU package. In FIG. 23, each application is directed to a control package (Cont. In FIG. 23) as a control unit in the OLT, an OSU package (OSU in FIG. 23) including a plurality of optical transceivers (λCard in FIG. 23), an OSU and They are classified into three groups suitable for SW packages that perform data input / output with devices on the upper network side. The OSU group is a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWBA application, an ONU registration authentication application, the SW group is an MLD proxy application, the Cont group is a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS- IF), a setting management application. Furthermore, although centralized control by the CPU is assumed, applications of each group may be distributed and arranged in respective packages (Cont, OSU, SW). In addition, regardless of the above classification, it may be arranged on any one of Cont, OSU, SW or a combination of a plurality of them. Further, the device setting IF in FIG. 23 may be a part of the EMS-IF, or may be equivalent to the device-dependent API 25 in FIG. Although the processing of the application is performed on the CPU, a part or all of the processing may be performed on a substitute having a processing function, for example, a processor other than the CPU, such as a GPU, an NPU, or a DSP, or an FPGA. The same applies to other embodiments.

  FIG. 24 is an example in which an application is arranged on a server or the like instead of the CPU package. The application is processed on a server or the like, and the processing result of the application is transmitted on a transmission path in a format that can be transmitted on a transmission path such as an Ethernet (registered trademark) frame, and then arrives at the OLT. Here, as a format that can be transmitted on the transmission path, a frame other than the Ethernet (registered trademark) frame, or transmission of TDM or the like may be used. Although the processing result is transmitted via a converter (Conv. In FIG. 24), if the OSU, SW or λ card can receive the processing result of the application without passing through the converter, the conversion is performed. No machine is required. The server or the like may be equivalent to the external server 16 in FIG.

However, the present invention is not limited to this classification. The CPU in FIG. 25 may be the CPU package in FIG. 24, the server or the like in FIG. 24, a location having other processing capability, or a combination thereof. The MAC of the OSU is assumed to be an LSI dedicated to OSU processing, but a general-purpose LSI may be used as long as equivalent processing is possible.

  FIG. 26 is a diagram showing processing of an application having eight main functions and the processing of the G.264 application. It is a figure showing an example of correspondence with 989.3 functions.

That is, FIG. 27 illustrates a process in which PLOAM and OMCI acquire corresponding data from the control unit 14 or the proxy unit 15 or the external server 16 in FIG. 8 via the SW in addition to the user data.

  A user data client (User Data Client) acquires data from a user data adapter (User Data Adapter) via a switch unit (SW). The user data client sends data to the user data adapter via the switch unit. The OMCI client of the CPU acquires data from the OMCI adapter via the switch unit. The OMCI client transmits data to the OMCI adapter via the switch unit.

  A TWDM TC function of the TWDM TC layer acquires data from an embedded header field via a switch. The TWDM TC function unit of the TWDM TC layer transmits data to the embedded header area via the switch unit.

  In the examples of FIGS. 3 and 4, the software areas are the basic function unit 132, the management / control agent unit 133, the extended function unit 131, and the middleware unit 120. Fragment processing, GEM framing / XGEM framing, PHY adaptation FEC, scrambling, synchronization block generation / extraction, GTC (GPON Transmission Convergences) framing, PHY framing, SP conversion, and encoding schemes may also be targeted.

In addition, when the transmission / reception unit receives an uplink signal that does not comply with the DBA, it may not follow the DBA application.

  The information processing unit is not limited to these software functions, and may have other software functions. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) are 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 transmitting / receiving unit, an OSU, a switch, and a control unit. Further, as shown in FIG. 8, a proxy unit or an external server for processing a signal input / output to / from the switch may be provided on the NNI (Network-Network Interface) side of the switch. The external server 16 may be an information processing function called a 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 the switch unit 12 or the switch unit 13, or may include a switch (the switch unit 12 when the switch unit 13 is provided) separately from the switch. It is desirable that the function of the switch is not shared between the switch unit 12 and the switch unit 13 and is appropriately shared according to the processing capability of the switch, but may be overlapped.

  The location where the software function is provided is not limited to the information processing unit, and may be provided at a plurality of locations where arithmetic processing is possible. For example, the location where the software function is provided is a transmitting / receiving unit, an OSU switch, an OSU switch, an OLT control unit, an OLT switch, an OLT information processing unit, an OLT switch, a control unit, and an information processing unit other than the OLT switch. The NNI side of the switch may be either a proxy unit that processes signals input to or output from the switch, or a processing device such as an external server.

  The arrangement of the software functions may be for each software function, or may be a part of a software function obtained by dividing a single software function. For example, a part related to the transmitting / receiving unit other than the transmitting / receiving unit, for example, an OSU switch, a unit other than the transmitting / receiving unit of the OSU and other than a switch, an OLT switch, an OLT control unit, an OLT information processing unit, and an OLT other than It may be provided anywhere outside the OLT, such as a proxy unit or an external server on the main signal path, or in a combination of a plurality of deployment locations. Items related to the PON termination other than the PON termination processing deployment location, such as the OSU transmission / reception unit, the OSU switch, the OSU transmission / reception unit and other than the switch, the OLT switch, the OLT control unit, and the OLT information processing unit , OLT, or a proxy unit or an external server on the main signal path outside the OLT or a combination of a plurality of deployment locations.

  Items related to ONU switches other than ONU switches, such as OLT switches, OLT control units, OLT information processing units, OLT other than OLT switches, other than transmission / reception units, OSU transmission / reception units and switches. May be arranged anywhere on the main signal path outside the server, such as a proxy unit or an external server, or in a combination of a plurality of arrangement places. Items related to the OLT switch are described in other places other than the OLT switch, for example, the transmission / reception unit, the OSU switch, other than the OSU transmission / reception unit and other than the switch, the OLT control unit, the OLT information processing unit, the OLT other than the OLT. May be arranged anywhere on the main signal path outside the server, such as a proxy unit or an external server, or in a combination of a plurality of arrangement places.

  In addition, the location where the software function is provided may be changed as appropriate in accordance with the deployment status of the extension function unit 131, the computing capacity, computing load, power consumption, and the like of the computable location.

  The main functions related to the main signal processing of the OLT and the relationship between the functions will be described. Transfer the OLT function to the switch. A PON main signal processing function for performing PON section processing such as a PHY adaptation function, a framing function, and a service adaptation function is provided in the transmission / reception unit. A PON access control function such as an ONU registration or authentication function, a DBA control function, and a DWA function is provided in the information processing unit. The switch is provided with L2 main signal processing functions such as VLAN control used in framing, priority control at the preceding stage of the shaper, max or demux (Mux / DMux) and queue (Queue), and shaper at the preceding stage of framing.

  A multicast function such as a copy function at the former stage of the shaper and an MLD proxy used for copying is provided in the switch. As described above, the PON main signal processing function and the PON access control function provided in the PON are provided in the switch, thereby reducing the PON basic function unit. In particular, it is preferable that the L2 main signal processing is arranged in a switch while avoiding duplication.

  In addition, as an example of a switch function, a classifier (a classifier), a modifier (a modifier), a policer / shaper (a policer / shaper), a cross connect (a cross connect), a queue (a queue), and a scheduler (a scheduler) are provided in order. However, it may be changed as appropriate. For example, if the processing is performed in the upstream direction and the processing is not performed in the bandwidth allocation unit, the input from the ONU is removed from the preamble and burst overhead for burst transmission, the frame is decapsulated, the LLID is removed, and the PON is removed. , Only the classifier, modifier, policer / shaper, cross connect, queue, and scheduler functions may be implemented by a switch, or only the modifier, cross connect, queue, and scheduler may be implemented by the switch.

  Furthermore, if a VID or the like describing a path or the like after the termination of the PON is given by the ONU, Cross Connect, Queue, and Scheduler may be used. If the upper network can be regarded as a single path, Queue and Scheduler may be used. Also, if a DBA is performed so that frames do not collide in the Cross Connect, a Classifier, a Modifier, a Policy / Shaper, and a Cross Connect can be obtained. Further, if the processing is performed in the upstream direction and the processing is not performed in the bandwidth allocation unit, the input from the ONU is removed from the preamble and the burst overhead for burst transmission, the frame is decapsulated, the LLID is removed, and the PON is removed. If only ON is terminated and a VID or the like describing a path or the like after the PON termination is given by the ONU, only Cross Connect can be used.

  In addition, Classifier, Modifier, Policy / Shaper, CrossConnect, Queue, and Scheduler, Classifier, Policy / Shaper, Modifier, CrossConnecter, CrossConnect, Queue, and Schueuler are also available. A modifier, a queue, a policer / shaper, a cross connect, and a scheduler, or a classifier, a queue, a policer / shaper, a modifier, a cross connect, and a scheduler may be used. Considering unnecessary policing / shaping (shaping) due to burstiness caused by multiplexing of priority traffic such as PON burst transmission and multicasting, and reception of leveled traffic on the receiving side, the policing / shaping of the policer / shaper is considered. It is desirable to perform processing by policing / shaping after leveling by placing a queue in the first stage.

  At the time of a state transition to a specific state, the subject of the sleep operation or the like stores an instruction of the subject of the sleep operation or the like (a device included in the communication device) outside the subject independent of the subject of the sleep operation or the like, The operation can be inherited. Specific states are, for example, a sleep state, a switching state of the active communication device, a user accommodation switching state, and a multicast state. Since the information is held outside the communication device, it is possible to prevent the inheritance of the sleep operation or the like from being lost when switching to another communication device. The communication device can ensure the inheritance of the information held by the device.

  In addition, by diverting a general-purpose, softwareized switch as an execution unit, it becomes possible to realize an OLT capable of adding a general-purpose, softwareized switch at low cost, flexibly, and quickly.

  The configuration according to Embodiment 1-1 described above is the same in the following embodiments, and may be appropriately combined. For example, FIG. 3 illustrates a case in which the system includes only the transmitting and receiving unit 11 (TRx), the switch unit 12, and the switch unit 13 in the execution unit, but the transmitting and receiving unit 11 (TRx), the switch unit 12, and the switch unit. 13, other places, a place where the PON ends, and the control unit 14 may be an execution unit.

(Embodiment 1-2)
In the embodiment 1-1, the configuration used for the TWDM-PON is illustrated, but the configuration may be applied to the TDM-PON. The TDM-PON is the same as the embodiment 1-1 except that it does not need to have a function of wavelength-division multiplexing the wavelength resources of the PON section of the ONU-OLT between ONUs, such as λ setting switching (DWA). It is.

(Embodiment 1-3)
In the embodiment 1-1, the configuration used for the TWDM-PON is illustrated, but the configuration may be applied to the WDM-PON. In the WDM-PON, the embodiment 1-3 is different from the embodiment 1-1 except that a function of performing time division multiplexing of a band resource of a PON section of an ONU-OLT between ONUs such as a DBA need not be provided. Is the same as

(Embodiment 1-4)
In the present embodiment, an OFDM (Orthogonal Frequency Division Multiplex) -PON, a CDM (Code Division Multiplex) -PON, a SCM (Subcarrier Multiplex) -PON, and a combination of core division and multiplexing.

  In the embodiment 1-1, the configuration used for the TWDM-PON is illustrated, but the configuration may be applied to a PON that shares resources other than wavelength and time. For example, the present invention may be applied to an OFDM-PON that divides and multiplexes one-frequency electric frequency resources, an SCM-PON that divides and multiplexes one-frequency electric frequency resources, a CDM-PON that divides and multiplexes by codes, and a core division. Multiplexing may be used together, space division multiplexing using a multi-core fiber or the like may be used together, or wavelength division multiplexing may not be used. The same applies if the function of wavelength-division multiplexing the wavelength resources of the TWDM-PON is read as a function corresponding to the function required to divide and multiplex the resources into the respective multiplexed resources.

(Embodiment 2)
In the second embodiment, the configuration used for the TWDM-PON performs GEM encapsulation. In this case, the switch is provided with an adapter that generates the GEM frame, and the GEM frame is conducted between the switch and other parts. By transferring to the switch until GEM encapsulation, the L2 function unit can be excluded from the protocol stack of the other part, and the L2 function unit can be prevented from overlapping the switch and the other part.

  The TWDM-PON has been described as an example. However, as in Embodiments 1-2 to 1-4, if a frame for identification in a PON section is handled in the same manner, the same applies to other PONs. The effect of is obtained. For example, in the case of the GE-PON, 10GE-PON, etc. of the IEEE standard, instead of the GEM frame, an LLID may be added so that the frame with the LLID is conducted between the switch and the other parts. Good.

(Embodiment 3)
In the third embodiment, control information used for TWDM-PON passes through a switch. In this case, instead of transferring the bridge function relation to the switch, any of PLOAM, Embedded OAM, and OMCI holding the control information is framed as necessary and processed via the switch. By inputting and outputting control information via a switch, there is an effect that processing other than the switch becomes lighter. Note that, in addition to the transfer of the third embodiment, the bridge function of the first and second embodiments may be transferred to a switch.

  Although the TWDM-PON has been described as an example, if control information is handled in the same way and processed via a switch, the same applies to other PONs as in the embodiments 1-2 to 1-4. The effect is obtained.
