(Embodiment 1)
FIG. 1 is a diagram illustrating a basic configuration of a communication device 100 related to a function of outputting an input to another device. The communication device 100 includes an execution unit 101, an instruction unit 102, and a restriction unit 103. The communication device 100 has a communication unit (not shown) that communicates with another external device. The execution unit 101 and the instruction unit 102 may be provided inside the communication unit, or may be provided outside the communication unit.

  The communication device includes, for example, an application (for example, a FASA application) that is a software component realized by using a general-purpose input / output interface (for example, a FASA application API) to perform different functions and the like for each service or each communication carrier. Basic components of an access network device that provides functions that do not need to be changed according to services and requests because the input / output interface generalized to the application is provided and standardized. ). 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.

The execution unit 101 is a function in the FASA base described in Non-Patent Document 2, for example.
The instruction unit 102 is a functional component that is replaced or added to the communication device 100. The instruction unit 102 is, for example, a FASA application described in Non-Patent Document 2, a software component based on FASA, a device-independent application unit described later, and the like.

  The restriction unit 103 performs the following processes (1) and (2) when replacing or adding functions. The restriction unit may be provided on the FASA base, may be provided as an application such as a setting management application, or may be provided at another location outside the device such as an NE controller or a proxy. The limiting unit may accept only an application in which the sum of the indexes of the applications accommodated before or after reception does not exceed a predetermined value, or may not accept an application that exceeds a predetermined value before or after reception. Good. The index may be, for example, a bandwidth or a bandwidth-time product of communication occurring between the application and the FASA infrastructure or between the applications or a combination thereof, a processing capability required by the application, or a combination thereof. There may be. The index may be an average value, a maximum value, or a statistical value such as a value obtained by multiplying a predetermined variance value by a predetermined coefficient from the average value. The average value can be processed on average, the maximum value can be processed even in the worst case, and the statistical value can be processed statistically using the average or variance. is there. This is the same in the subsequent processing.

  (1) The restricting unit 103 sets the remaining amount of a predetermined index (hereinafter referred to as a “resource index”) relating to resources used when the communication equipment 100 or an application, a predetermined predetermined type of application, or a combination thereof operates. Obtain the statistically processed value. The remaining amount of the resource index or the value obtained by performing the statistical processing indicates an index of a resource that can be used in the communication device 100 and is unused at that time. The limiting unit 103 performs statistical processing such as adding a resource index value related to a function to be removed by replacement of a function (for example, the instruction unit 102) to the remaining amount of the resource index. In addition, the restriction unit 103 subtracts the value of the resource index related to the function added by the replacement of the function from the remaining amount of the resource index. In addition, the limiting unit 103 subtracts the value of the resource index related to the newly added function from the remaining resource index. When the remaining amount of the resource index does not exceed a predetermined value, the restriction unit 103 restricts replacement or addition of a function to the communication device 100. The limited replacement or addition may be addition performed by replacement of functions or may be new addition. On the other hand, when the remaining amount of the resource index exceeds the predetermined value, the limiting unit 103 does not limit the addition of the function to the communication device 100. Here, the addition and subtraction may be performed by statistical processing such as multiplication by a predetermined weight. For example, a resource use probability may be multiplied as a weight, a value obtained by adding or subtracting a variance value of a predetermined coefficient to an average value may be used, or a resource may be used intermittently and a cycle of intermittently using the resource may be used. May be added or subtracted only for resources that are synchronized if they are synchronized, or the probability that the time to use resources will collide if resources are used intermittently but the cycle is not synchronized May be multiplied. Processing may be performed assuming that resources cannot be used at the time or probability of releasing resources of an environment such as an application or an OS, or at the time or probability that resources cannot be reused without being released. This is the same in the subsequent processing.

  (2) The restricting unit 103 is configured to calculate the total value of resource indexes (hereinafter, referred to as a function related to a function to be replaced or a function to be newly added in the communication device 100 or an application or a predetermined type of application or a combination thereof). Statistical processing such as subtracting the value of the resource index related to the function removed by the replacement of the function from the “resource total value”) or the statistically processed value is performed. The restriction unit 103 adds the resource index of the function added by the replacement or the function newly added to the resource total value after the subtraction or the value obtained by the statistical processing. When the total resource value after addition or the value obtained by statistical processing thereof exceeds a predetermined value, the restriction unit 103 restricts replacement or addition of a function to the communication apparatus 100. On the other hand, if the total value of the resource indicators or the value obtained by statistical processing does not exceed the predetermined value, the restriction unit 103 does not restrict the replacement or addition of functions to the communication device 100.

  (3) The limiting unit 103 is a function that is removed by replacing the function with respect to a resource index that is a predetermined index related to a resource used when the communication device 100 or an application, a predetermined application of a predetermined type, or a combination thereof operates. Based on the resource index related to the function, the resource index value related to the function added by the replacement of the function or its statistically processed value, and the resource index value related to the function newly added to the device or its statistically processed value. If the value of the resource used or its statistically processed value exceeds a predetermined value, the replacement or addition of the function to the own device is restricted, and the resource used does not exceed the predetermined value. Does not limit the addition of the function to its own device.

  Here, as the predetermined index, the number of functions, the number of steps for processing functions, the size of functions, the amount of memory for arranging functions, the amount of logic circuits for arranging functions, the amount of processing of related arithmetic units such as CPUs, The frequency, the bandwidth used for the input / output, the collision probability of the exchange schedule, the number of pages of paging, the paging frequency, the processing time, and the like, and combinations thereof. The values are the expected maximum, average, and other statistics.

  Examples of the predetermined type of predetermined application include, for example, DBA (Dynamic Bandwidth Assignment) that requires high-speed processing, main signal processing such as a filter, protection processing, and frame copying. By restricting the replacement or addition of an application that does not exceed the resource value secured for the predetermined processing or the statistically processed value in such high-speed processing as described above, processing of a predetermined predetermined type of application Reduces the probability of exceeding a predetermined resource, and enables stable operation.

  The restriction unit 103 may be located inside or outside the communication device 100, may include a part or a part of the instruction unit 102 in the device such as a FASA application related to the setting management function, or may include the execution unit 101 or It may be included in a FASA base or the like, or may be included in a device management system or the like.

  The communication device 100 is a device that executes communication with another communication device by a signal such as an optical signal transmitted through a communication network such as an optical fiber network such as a PON. The communication device 100 is, for example, an OLT. The communication device 100 may be, for example, an OSU (Optical Subscriber Unit). The communication device 100 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 100 may be, for example, a combination of an OLT and an ONU. The communication device 100 may include a plurality of devices.

  The exchange between the execution unit 101 and the instruction unit 102 is performed via middleware, which will be described later. Alternatively, an original transfer path or means of the communication device 100 may be used, or OPENFLOW, NETCONF / YANG, or SNMP (Simple Network Management Protocol) may be used. ) May be used.

  Next, as an example, an operation and the like are illustrated on the premise of a PON OLT 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 that conforms to the IEEE standard such as GE (Gigabit Ethernet (registered trademark))-PON and 10GE-PON. The same applies if the TC (Transmission Convergence) layer and the PMD (Physical Medium Dependent) layer are read as corresponding layers in the standard.

(Embodiment 1-1)
In Embodiment 1-1, a configuration of a communication device 100 configuring a communication system used for a TWDM-PON will be described. Hereinafter, first to sixth examples will be described as examples of the architecture of the communication device 100. The architecture of the communication device 100 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 100 in the first to sixth examples of the architecture may be a hardware unit.

(First example of architecture)
FIG. 2 is a diagram illustrating a first example of the architecture of the communication device. In the following description, the description of the reference numerals shown in FIG. 1 will be omitted to reduce the complexity of the reference numerals. In the first example of the architecture, the communication device includes a device-dependent unit that depends on a compliant standard or a vendor, a middleware unit that conceals differences between hardware and software of the device-dependent unit, and a general-purpose device whose operation does not depend on the device. It has a device-independent application section. Therefore, the device-dependent unit (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. The device-independent application unit is a functional unit that does not depend on the standard or the manufacturer of the device of the communication device.

The middleware unit and the device-independent application unit are connected via a device-independent API. The device-independent API is an input / output IF that does not depend on the device.
The device dependent unit includes, for example, a hardware unit (PHY), a hardware unit (MAC), a software unit, and an OAM (Operation Administration and Maintenance) unit. The hardware unit, the hardware unit, the software unit 3 and the OAM unit are connected to the middleware unit via a device-dependent API. The device-dependent API is an input / output IF that depends on the device. The device dependent unit further includes a NE (Network Element) management / control unit. The NE management / control unit and the middleware unit are connected via a device-dependent API. The device-dependent API is an input / output IF that depends on the device.

  The functions to be used as the device-dependent unit or the device-independent application unit are determined in addition to the restrictions derived from the processing for realizing the middleware unit and the device-independent application unit, for example, in addition to the restrictions derived from the processing capability of the software. Alternatively, it 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 add the extended function unit (unique function unit) by the device-independent application unit, and can provide the communication service in a timely manner.

  For example, priority is given to functions that frequently update such as priority processing of main signals and DBA (Dynamic Bandwidth Assignment) for improving line utilization efficiency or functions that contribute to the differentiation of communication services. Department. Furthermore, since there is little difference between at least one of the standard, the generation, the system, the system, the device type, and the manufacturer of the device to be shared, the device-independent application unit may be used.

  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, generation, method, system, device type, and manufacturing vendor based on the device-dependent unit.

  A middleware unit shown in FIG. 2 and FIG. 3 described later, a driver of a device dependent unit shown in FIG. 4 and FIG. 5 described later, and a device dependent application unit (vendor dependent application) shown in FIG. 3 and FIG. And / or a function unit for automatically setting an IF, a parameter, or the like corresponding to a device-dependent unit, or a function unit for automatically setting a corresponding IF, parameter, or the like. .

  In FIG. 2, the device dependent unit includes a hardware unit (PHY) and a hardware unit (MAC), and a software unit. The hardware unit (PHY) executes a process from the physical layer to processes related to optical transmission / reception (PHYsical sublayer process). The hardware unit (MAC) executes a MAC (Media Access Control) process. The hardware section and the hardware section depend on the standard or manufacturing vendor with which it complies. The software unit executes a device-dependent driver, firmware, application, and the like.

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

  The device-independent application unit includes, for example, an extended function unit, a basic function unit, and a management / control agent unit. The management / control agent unit acquires data from an EMS (Element Management System). In the figure, the EMS and the external device are connected to the device-independent application via the middleware, but the EMS and the external device do not necessarily need to be connected to the device-independent application via the middleware. The EMS and the external device may be appropriately connected to the middleware as needed, or may be directly connected to the device-independent application. In addition, the expression "connection via middleware" is an expression from the viewpoint of a device-independent application. Actually, function-independent applications are connected via middleware after connection by hardware.

  Hereinafter, items common to the extended function units will be referred to as “extended function units” by omitting some of the reference numerals. The EMS is, for example, a controller of the NE. The device-independent application section may not include any of the extended function section, the basic function section, and the management / control agent section, or may include the management / control agent section in the basic function section. Alternatively, the management / control agent unit may be included in the basic function unit or the middleware unit.

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

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

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

  The management / control agent unit does not need to input / output to / from the EMS when receiving the communication from the EMS and automatically performing the setting according to the predetermined setting. Furthermore, if the management / control agent unit does not have the management setting function and the other device-independent application unit, basic function unit, or device-dependent unit has the management setting function, the device-independent application unit May not be provided.

  The EMS and the device-independent application unit may directly input and output information. Further, the device-dependent unit may be replaced by a NE management / control unit and a device-dependent application unit (see FIG. 3 described later and FIG. 5 described below) of a functional unit below the NE management / control unit.

  The management / control agent unit does not need to input / output information to / from the EMS when performing automatic setting according to a predetermined setting. Furthermore, if the management / control agent unit does not have the management setting function and the other device-independent application unit, basic function unit, and device-dependent unit have the management setting function, the device-independent application unit It is not necessary to prepare. The EMS and the device-independent application unit may directly input and output information.

An example of input and output between the device-independent application unit and the device-dependent unit 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. The DWBA (Dynamic Wavelength and Bandwidth Assignment) 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). 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 framer (XGPON Encapsulation Method Framer) and encryption. Here, the DWBA and the DBA may be separate, integrated, or combined. For example, the management / control agent unit is an application unit of a maintenance operation function, and mutually inputs and outputs information with EMS which is an NE controller or the like for the NE management / control unit.

  The implementation of the device-independent application unit may have a priority. For example, the management / control agent unit 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 includes a device vendor, a method, a device type, and a device generation, for example, ITU-T G.300. 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 independently of any B (Broadband) PON that conforms to the 983 series. The device-independent application unit 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 app that works regardless of at least one of them.

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

  The management / control agent unit inputs and outputs with the EMS and the middleware unit. The middleware unit inputs / outputs NE management information and control information from / to the NE management / control unit. The NE management / control unit may transmit / receive NE management information and control information directly to / from the EMS without passing through the middleware unit, or may transmit / receive the NE management information and control information to / from the EMS via the management / control agent unit. Is also good.

  The middleware unit inputs and outputs information via the device-independent application unit and the device-independent API. The middleware unit inputs / outputs information via the device-dependent API to / from the OAM unit, driver, firmware, hardware unit, or hardware unit of the device-dependent unit. The middleware unit 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, the middleware unit converts the information into the input format of each unit of the device-independent API. If the output destination is an OAM section, a driver, firmware, a hardware section, or a hardware section of a device-dependent portion, the middleware portion converts the input format into a device-dependent API format to be input to each device, or terminates the conversion. After performing a predetermined process, the information is transmitted to the output destination.

  At the time of input, the middleware unit preferably deletes unnecessary input information at each input destination, and collects and supplements any missing information via another device-independent API or a device-dependent API. . In addition, upon input to the middleware unit, the information may be broadcast or multicast to broadcast to related applications and the like.

  In FIG. 2, the middleware unit and the device-dependent unit are illustrated as a single unit, but 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, the middleware unit may perform input / output by using inter-processor communication or the like across processors and hardware. The device-independent application sections and the device-independent application sections 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 in a user space on a plurality of processors. It may be placed on top.

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

  A device-independent application unit 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.

  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 (see FIG. 3 to be described later and FIG. 5 to be described later) is arranged is also subjected to actual processing from the viewpoint of the restriction on the bus and speed due to the inter-processor communication and the effect on other programs due to the occupation of the communication path and the like. It is desirable to arrange in a user space, a kernel space, or firmware of a processor that performs the above 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 be provided in the middleware unit in advance, assuming an extended function unit to be added. However, the device-independent API is added as necessary in a form that suppresses modification of the device-dependent API and other device-independent application units. Or it may be deleted.

  In this example, the software area is a basic function section, a management / control agent section, an extended function section, and a middleware section. However, the software area is a service adaptation (encryption, fragment processing, GEM framing / XGEM The framing, FEC of PHY adaptation, scrambling, synchronization block generation / extraction, GTC (GPON Transmission Convergences) framing, PHY framing, SP conversion, and coding method may also be targets. An example of a hardware unit and a function allocation corresponding to the hardware unit will be described, for example, a network device or an external server has a software function, which is the same in other examples.

(Second example of architecture)
FIG. 3 is a diagram illustrating a second example of the architecture of the communication device. In FIG. 3, the communication device has a configuration further including a device-dependent application unit under the middleware unit of the communication device shown in FIG. The second example of the architecture is the same as the first example of the architecture except that it has a device-dependent application unit.

  The middleware unit and the device-dependent application unit are connected by a device-dependent API. The device-dependent application unit and the OAM unit, software unit, hardware unit, and hardware unit of the device-dependent unit are connected by a device-dependent API. The device-dependent application unit and the management / control agent unit are connected by an API.

  The device-independent application unit includes, for example, a management / control agent unit that receives communication from the EMS, a basic function unit, and an extended function unit. The device-independent application unit may not include any of the management / control agent unit, the basic function unit, and the extended function unit, as in the first example of the architecture.

When the extension function unit includes the basic function unit, when the lower part of the middleware unit substitutes for the basic function unit, or when they are a combination thereof, the device-independent application unit may not include the basic function unit.

  Further, a part of the basic function unit may be replaced with a device-dependent application unit below the middleware unit. The management / control agent unit does not need to input / output information to / from the EMS when performing automatic setting according to a predetermined setting. Furthermore, if the management / control agent unit does not have the management setting function and the other device-independent application unit, basic function unit, or device-dependent unit has the management setting function, the device-independent application unit will use the management / control agent unit. May not be provided.

  The EMS and the device-independent application unit may directly input and output. When the lower part of the middleware unit replaces all of the basic function units, the device-independent application unit may not include the basic function unit.

  In the communication device shown in FIG. 3, the device-dependent application unit may input and output information via the middleware unit, may directly input and output information from the management / control agent unit, or Information may be input to or output from any of them, or may be directly input to or output from the EMS. If the device-dependent application unit is automatically set according to a predetermined setting without receiving communication from the EMS and can acquire management and control information from the EMS through the middleware unit, the device-independent The application unit does not need to include the management / control agent unit.

  The device-independent application unit inputs and outputs information via at least the hardware unit and the hardware unit of the device-dependent unit or the software unit via the middleware unit. The device-independent application units mutually input and output via a middleware unit as needed. In particular, when the device-independent application unit performs control or management in accordance with information input / output to / from the EMS, the device-independent application unit inputs / outputs information to / from a management / control agent unit receiving communication from the EMS. I do.

  The NE management / control unit inputs and outputs NE management information and control information with the management / control agent unit via the middleware unit. The NE management / control unit may directly input and output NE management information and control information with the EMS without going through the middleware unit.

  The device-dependent application unit inputs and outputs NE management information and control information with the management / control agent unit. The device-dependent application unit may directly input and output information to and from the EMS without going through the management / control agent unit. The management / control agent unit inputs and outputs information between the EMS, the middleware unit, and the device-dependent application unit. The middleware unit inputs / outputs NE management information and control information from / to the NE management / control unit.

  The NE management / control unit may directly input and output NE management information and control information with the EMS without going through the middleware unit. The middleware unit inputs and outputs information to and from the device-independent application unit via a device-independent API, and communicates with the OAM unit, driver, firmware, hardware unit, and hardware unit of the device-dependent unit. Information is input and output via a device-independent API.

  The middleware section is input as it is or in a predetermined format, similarly to the middleware section shown in FIG. It is desirable that the device-independent API be provided in the middleware unit in advance, assuming an extended function unit to be added later. However, if necessary, the device-dependent API and other device-independent application units can be prevented from being modified. May be added or deleted.

(Third example of architecture)
FIG. 4 is a diagram illustrating a third example of the architecture of the communication device. In FIG. 4, instead of the middleware unit described in the first example of the architecture shown in FIG. 2, the basic function unit performs input / output with the hardware unit and the hardware unit, and the extended function unit. The other device-independent application units are the same as in the first example of the architecture.

  Compared to the first example of the architecture, the third example creates a middleware unit having a device-dependent API for each device that differs from at least one of the compliant standard, generation, method, system, device type, and manufacturing vendor. No need. As a result, the communication device of the third example of the architecture has the effect of generalizing and porting more functions between generations between devices, facilitating verification of connectivity, and enhancing the function of the devices.

  The communication device according to the third example of the architecture includes a device dependent unit and a device independent application unit. The device-dependent unit includes a hardware unit and a hardware unit that depend on a compliant standard or a device manufacturing vendor, and a software unit such as a driver that drives the hardware unit and a firmware that drives the hardware unit. The driver or the like hides the difference between the device dependent units.

  The device-independent application unit includes an extended function unit and a basic function unit. The basic function unit is connected to the device-dependent unit by a device-independent API (porting IF) via a hardware unit and a driver that conceals the difference between the hardware unit and the device-dependent software unit. The device-independent application unit transmits data between the hardware unit and the hardware unit and the device-dependent software unit via a driver that conceals the difference between the hardware unit and the hardware unit and the device-dependent software unit. Input and output.

  The basic function unit and the extended function unit are connected via a device-independent API (expansion IF). The basic function unit and the device-dependent unit are connected via a device-independent API. The basic function unit in the device-independent application unit inputs and outputs information between the hardware unit and the hardware unit or the extended function unit instead of the middleware unit.

  The device-independent application units mutually input and output via the basic function unit as needed. The extended function unit of the device-independent application unit inputs and outputs information via the basic function unit and the device-independent API. The basic function unit inputs / outputs information via the device-independent application unit and the device-independent API, and transmits / receives information via the device-dependent unit's OAM unit, driver, firmware, hardware unit, and the hardware unit and the device-independent API. Input and output information.

  The basic function unit inputs operation information as it is or in a predetermined format, similarly to the middleware unit shown in FIG. For example, if it is another device-independent application unit, the basic function unit converts the input format into a device-independent API format, and if it is a device-dependent OAM unit, a driver, firmware, or a hardware unit. After converting the input format into the device-independent API format, or after terminating and performing a predetermined process, the operation information is input. At the time of input, the basic function unit deletes unnecessary input information at each input destination, and collects and supplements any missing information via another device-independent API or a device-independent API. Is desirable. However, the basic function unit 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 includes, for example, an extended function unit and a basic function unit. The device-independent application unit may not include any of the extended function unit and the basic function unit. The device-independent application unit may further include a function unit other than the extension function unit and the basic function unit. For example, when the extension function unit is unnecessary, the device-independent application unit may not include the extension function unit.

  It is preferable that the extension function unit can be added or deleted independently without affecting other functions. For example, in response to a request on the service, for example, when a multicast service, power saving support is used as an extended function unit, if an extended function unit is required, it is added as appropriate, and if it is unnecessary, it is deleted as appropriate, It may be replaced or changed according to the change.

  It is desirable that the device-independent API be provided in the basic function unit in advance, assuming an extended function unit to be added later. However, if necessary, the device-independent API, the device-independent API, and other device-independent applications can be used. It may be added or deleted in a form that suppresses modification of the part.

(Fourth example of architecture)
FIG. 5 is a diagram illustrating a fourth example of the architecture of the communication device. The difference between the fourth example of the architecture and the third example of the architecture is that the communication device includes a device-dependent application unit under the basic function unit. Thus, the communication device of the fourth example of the architecture has the effect that the configuration of the basic function unit can be simplified by including the device-dependent application unit.

  The communication device illustrated in FIG. 5 includes a device-dependent unit and a device-independent application unit. The device-dependent unit includes a hardware unit and a hardware unit depending on a compliant standard or a device manufacturing vendor, a hardware unit and a software unit such as a driver and firmware for driving the hardware unit, and at least a part of the device-dependent unit. And a device-dependent application unit that drives the device. The device-independent application unit depends on the device through the porting IF and the hardware unit, or through a driver that conceals the difference between the hardware unit and the device-dependent software, or through the porting IF and the device-dependent application unit. It is a general-purpose device-independent application that performs processing that does not require. The basic function unit in the device-independent application unit and the device-dependent application unit in the device-dependent unit are connected via a device-independent API. The device-dependent application unit and the device-dependent unit are connected via a device-dependent API.

  As for the basic function unit in the device-independent application unit, the basic function unit performs input / output with hardware and the extended function unit instead of the middleware unit. The basic function unit may include a management / control agent unit that receives communication from the EMS, or may include a management / control agent unit as an extended function unit.

  The basic function unit inputs / outputs via a device-independent application unit and a device-independent API (expansion IF), an OAM unit of a device-dependent unit, a driver, firmware, a hardware unit, and a hardware unit and a device-independent API. (Porting IF) and a device-dependent unit driver that conceals the difference between the device-dependent unit and a device-dependent application unit and input / output via a device-dependent API.

  The basic function unit is input as it is or in a predetermined format, similarly to the middleware unit shown in FIG. As in the third example of the architecture, the basic function unit may include a management / control agent unit that receives communication from the EMS, or may include a management / control agent unit as an extended function unit. .

  The device-independent application unit includes, for example, an extended function unit and a basic function unit. The device-independent application unit may not include any of the extended function unit and the basic function unit, as in the third example of the architecture. The device-independent application unit may further include a function unit other than the extended function unit and the basic function unit, as in the third example of the architecture.

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

  As in the first example of the architecture shown in FIG. 2, the device-independent API is desirably provided in advance in the basic function unit, assuming an extended function unit to be added later. APIs, other device-independent application units, device-dependent application units, or device-dependent APIs may be added or deleted as needed in a manner that suppresses modification.

(Fifth example of architecture)
The upper right diagram of FIG. 6 is a diagram illustrating a fifth example of the architecture. The lower right part of FIG. 6 corresponds to first to fourth examples of the architecture. 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 that depends on the device, a middleware unit that hides the difference between hardware and software on external hardware, and a general-purpose device that does not depend on the device. And an independent application section. 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 is a functional unit that does not depend on the standard or the manufacturer of the device of the communication device.

  The middleware unit and the device-independent application unit are connected via a device-independent API that is an input / output IF that does not depend on the device. For example, the software part, the OAM, the hardware part, and the hardware part of the equipment dependent part and the middleware part on the external hardware are the equipment dependent API which is the input / output IF depending on the equipment and the existing / commercial hardware. It is connected via a connection between devices between hardware and external hardware.

  The execution unit 3 is disposed in a device-dependent unit, and the instruction unit 5 is disposed in, for example, a device-independent application unit. This architecture facilitates flexible and quick addition of an extended function unit (unique function unit) by the device-independent application unit, and can provide a communication service in a timely manner. Here, the device-dependent unit may be the maintenance operation, access control, physical layer processing, or optical module shown in FIG. 6, depending on the configuration of the device itself.

  For example, priority is given to a function with a high update frequency such as a priority processing of a main signal or a DBA for improving line utilization efficiency or a function contributing to the differentiation of communication services, and a device-dependent portion or a device-independent application portion is to be used. You may decide. Furthermore, since there is little difference between at least one of the standard, the generation, the system, the system, the device type, and the manufacturer of the device to be shared, the device-independent application unit may be used.

  Here, the device-dependent unit is the execution unit, and the device-independent application is the instruction unit. However, both may be device-independent applications or both may be device-dependent units depending on the function allocation. Examples of both device-independent applications include, for example, an information processing unit such as a processor provided with an implementation unit for a function such as DBA processing in a weak transceiver, and an instruction unit with other components having strong information processing capability. In this case, communication between processors and communication between devices work as middleware in the information processing unit, for example, the OSU. The case where both are provided in the device dependent unit is a case where the DBA function is compiled as a part of the firmware or the like as in the example on the left.

  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, generation, method, system, device type, and manufacturing vendor based on the device-dependent unit.

  At least one of a middleware unit, a device-dependent unit driver, and a device-dependent application unit (vendor-dependent application unit). A function unit for automatically setting according to an IF, a parameter, or the like may be further provided.

The device dependent unit 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 may not include a PMD and a MAC connected to the physical medium, a PMA that serializes data, and a part of the PCS or 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 is, for example, a management / control agent unit that acquires data from the EMS, an extended function unit, and a basic function unit. Hereinafter, items common to the extended function units will be referred to as “extended function units” by omitting some of the reference numerals. The EMS is, for example, a controller that controls a network element. Note that the device-independent application section may not include any of the management / control agent section, the extended function section, and the basic function section.

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

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

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

  The management / control agent unit does not need to input / output to / from the EMS when receiving the communication from the EMS and automatically performing the setting according to the predetermined setting. Furthermore, if the management / control agent unit does not have the management setting function and the other device-independent application unit, basic function unit, or device-dependent unit has the management setting function, the device-independent application unit May not be provided.

The EMS and the device-independent application unit may directly input and output information. Further, the device dependent unit does not have to include the NE management / control unit and the IF of the NE management / control unit.
The basic function unit may be included in the device-independent application unit as a part of the extended function unit, or may be replaced by a lower function unit of the middleware unit. When the extended function part includes the basic function part, when the lower function part of the middleware part replaces the basic function part, or when they are a combination of these, the device-independent application part does not need to include the basic function part. Good. Further, a part of the basic function unit may be replaced by a device-dependent application unit of a function unit below the middleware unit.

  The management / control agent unit does not need to input / output information to / from the EMS when performing automatic setting according to a predetermined setting. Further, when the management / control agent unit does not have the management setting function and the other device-independent application unit, the basic function unit, and the device-dependent unit have the management setting function, the device-independent application unit includes the management / control agent unit. It is not necessary to prepare. The EMS and the device-independent application unit may directly input and output information.

  An example of input and output between the device-independent application unit and the device-dependent unit 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 is an application unit of a maintenance operation function, and mutually inputs and outputs information with EMS which is an NE controller or the like for the NE management / control unit.

  The implementation of the device-independent application unit may have a priority. For example, the management / control agent unit 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 includes a device vendor, a method, a device type, and a device generation, for example, ITU-T G.300. 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 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 app that works regardless of at least one of them.

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

  The management / control agent unit inputs and outputs with the EMS and the middleware unit. The middleware unit inputs / outputs NE management information and control information from / to the NE management / control unit. The NE management / control unit may transmit / receive NE management information and control information directly to / from the EMS without passing through the middleware unit, or may transmit / receive the NE management information and control information to / from the EMS via the management / control agent unit. Is also good.

  The middleware unit inputs and outputs information via the device-independent application unit and the device-independent API. The middleware unit inputs / outputs information via the device-dependent API to / from the OAM unit, driver, firmware, hardware unit, or hardware unit of the device-dependent unit. The middleware unit 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, the middleware unit converts the information into the input format of each unit of the device-independent API. If the output destination is an OAM section, a driver, firmware, a hardware section, or a hardware section of a device-dependent portion, the middleware portion converts the input format into a device-dependent API format to be input to each device, or terminates the conversion. After performing a predetermined process, the information is transmitted to the output destination.

  At the time of input, the middleware unit preferably deletes unnecessary input information at each input destination, and collects and supplements any missing information via another device-independent API or a device-dependent API. . In addition, upon input to the middleware unit, the information may be broadcast or multicast to broadcast to related applications and the like.

  Although the middleware unit and the device-dependent unit 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, the middleware unit may perform input / output by using inter-processor communication or the like across processors and hardware. The device-independent application units and the device-independent application units 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. Is also good.

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

  A device-independent application unit 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.

  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 is arranged is also limited in terms of the bus and speed due to inter-processor communication, and from the viewpoint of the influence on other programs due to the occupation of the communication path, etc. It is desirable to place it in 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 be provided in the middleware unit in advance, assuming an extended function unit to be added. However, the device-independent API is added as necessary in a form that suppresses modification of the device-dependent API and other device-independent application units. Or it may be deleted.

(Sixth example of architecture)
A sixth example of the architecture includes a hardware unit and a hardware unit depending on a standard or a device manufacturing vendor that conforms as a device-dependent unit, a software unit such as a driver / firmware that drives the hardware unit and the hardware unit, A device-dependent application unit that drives at least a part of the device-dependent unit.

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

  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.

It is called "8 main functions".

  FIG. 7 shows a configuration in which the transmission / reception unit 11 for transmitting / receiving (communicating) optical signals of different wavelengths (λA to λN) is connected to the same switch unit 12, but Embodiment 1-1 is not limited to this. 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).

The OSU may be composed of a transmission / reception unit 11 (TRx), may be composed of a transmission / reception unit 11 (TRx) and a switch unit 12 (SW), or may be composed of a transmission / reception unit 11 (TRx) and a switch. And a unit 13 (SW).

  A transmitting / receiving unit 11 (TRx) for transmitting and receiving optical signals of different wavelengths (λA to λN) is connected to the switch unit 12. The transmission / reception unit 11 (TRx) performs autonomous control, or is controlled by other components such as the switch unit 12 (SW), the switch unit 13 (SW), the control unit 14, the proxy unit 15, or the external server 16, Alternatively, it is controlled by an instruction transferred via another component such as the switch unit 12 (SW), the switch unit 13 (SW), the control unit 14, the proxy unit 15, or the external server 16. The transmission / reception unit 11 (TRx) provides a VLAN (Virtual Local Area Network), priority, discard priority or destination to a part or all of the traffic of the ODN (Optical Distribution Network) or the switch unit 12 (SW) according to a predetermined procedure. Processing of at least one of aggregation, distribution, distribution, duplication, wrapping, or transmission, or the addition, deletion, or replacement of tags of at least a part of or a combination thereof, or without changing the tags I do.

  Note that the upstream traffic is not always aggregated.

As an example of the function assignment, an application may be used except for the hardware Config, and the application and the setting data may be an application on the external server 16 in FIG. 7 without having the ONU or OLT. It can also be realized by unifying commands and defining sequences.

  FIG. 14 is a diagram illustrating a second example of the configuration of the functions of the maintenance operation function unit 330.

Alternatively, processing by an application that cuts off an IF, such as reading a notification from a device-dependent unit, transmitting a notification to a network (NW), and writing to a file, may be used.

  FIG. 15 is a diagram illustrating a third example of the functional configuration of the maintenance operation function unit 330. 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 for this processing, a physical layer OAM (PLOAM: Physical Layer OAM) message and a bit indication (Embedded OAM) in the header are used.

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

Good. The sleep proxy / traffic monitor, ONU wavelength setting, and inter-wavelength setting transition may be realized by combining the same processing with the basic processing. In addition, the order may be changed.

  This main function requires that the transmission / reception rise time (receiver / transmitter) comply with 10 ms / 5 ms and the rise time (LC / OSU / OLT) follow 100 ms / 1 sec / 10 sec. Can be

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

  FIG. 18 is a diagram illustrating an example of a functional configuration of the frequency / time synchronization function unit 370. The OLT subordinately synchronizes its 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 a device-dependent unit, and the time adjustment calculation for the higher-level device can be performed by an application (the device can also be a device-dependent unit depending on accuracy).

  FIG. 19 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 composed of 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 in the software area is a device-independent application section on a device-independent API. 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 differentiated service are handled as an extended function unit in the device-independent application unit. The MLD proxy application includes a multicast function.

  The extension function unit is an extension function unit according to the degree of importance such as the frequency of updating the function or the realization of a unique specification among the applications. Those whose update frequency is low or whose demand for realization such as original specifications is low are preferably middleware units other than the basic function unit and the device-independent application unit, device-dependent software, hardware units, and hardware units. In particular, it is preferable that functions having restrictions due to the processing capability of software remain as hardware units and hardware units. 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 From the control function to the extended function part.

  The information processing unit is not limited to these software functions, and may have other software functions. The hardware unit and the hardware unit are not limited to the transmitting / receiving unit, the OSU, the switch, the control unit, and the 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. As shown in FIG. 7, a proxy unit or an external server that processes signals input to and output from the switch may be provided on the NNI (Network-Network Interface) side of the switch. The external server 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.

Further, the location where the software function is provided may be changed as appropriate in accordance with the state of deployment of the extended function unit, the computing capacity, computing load, power consumption, etc. 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 operation 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, software-ized switch as the execution unit 3, it becomes possible to realize an OLT capable of adding a general-purpose, software-ized switch at low cost, flexibly, and quickly.

  As described above, in the embodiment 1-1, by separately arranging the instruction unit 5 and the execution unit 3, the inheritance of the information held by the device is increased in the time required for sleep, switching, and user / accommodation replacement. Possible without.

  The configuration according to Embodiment 1-1 described above is the same in the following embodiments, and may be appropriately combined. For example, FIG. 2 illustrates a case where the execution unit 3 includes only the transmission / reception unit 11 (TRx), the switch unit 12, and the switch unit 13 in FIG. 2, but the transmission / reception unit 11 (TRx), the switch unit 12, and the switch unit A location other than the section 13, a location other than the section 13, a location where the PON terminates, and the control section 14 may be the execution section 3.

(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)
The present embodiment is a combination including OFDM (Orthogonal Frequency Division Multiplex) -PON, CDM (Code Division Multiplex) -PON, SCM (Subcarrier Multiplex) -PON, and core division 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.

  As described above, a communication device that communicates with another device sets in advance a response to an input that is assumed in advance in a module relating to exchange with another device, and determines the validity of the response during or after the response. Judge and correct the response if it is not valid.

  That is, the execution unit 3 of the communication device outputs a response, which is an input to another device, that responds to an input from the other device based on the settings made in advance. The execution unit 3 outputs an input to another communication device based on an instruction from the instruction unit 5. The instruction unit 5 verifies the validity of the response output by the execution unit 3 and, when determining that the response is not valid, inputs an input to another device for correcting the response determined to be invalid. A process for instructing the execution unit 3 to output is performed, or a process for setting a response to be output next to the response determined to be invalid in the execution unit 3 is performed. The instruction unit 5 outputs an instruction to the execution unit 3 before the execution unit 3 can correct the response within a period in which an invalid response is allowed. If the instruction unit 5 determines that the response is valid, the instruction unit 5 does not output an instruction to the execution unit 3 or performs a process of setting a response to be output next to the response in the execution unit 3. The communication device includes a communication unit that communicates with another device. The execution unit 3 and the instruction unit 5 may be provided inside the communication unit or may be provided outside. For example, among the modules constituting the communication device, the execution unit 3 can be realized by a module having a low processing capability, and the instruction unit 5 can be realized by a module having a high processing capability.

  At least a part of the communication device in the above-described embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read and executed by a computer system. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, and a CD-ROM, and a storage device such as a hard disk built in a computer system. Further, a “computer-readable recording medium” refers to a communication line for transmitting a program via a network such as the Internet or a communication line such as a telephone line, which dynamically holds the program for a short time. Such a program may include a program that holds a program for a certain period of time, such as a volatile memory in a computer system serving as a server or a client in that case. The program may be for realizing a part of the functions described above, or may be a program that can realize the functions described above in combination with a program already recorded in a computer system, It may be realized using a programmable logic device such as an FPGA (Field Programmable Gate Array).
