Embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a diagram showing a configuration example of a data processing device 1 of this embodiment. In FIG. 1, only functional blocks related to this embodiment are extracted and shown. The data processing device 1 includes a holding unit 2 holding a plurality of parts, an information unit 3 holding information about parts, and an output for outputting input data or the output of the parts in the previous order to a specific part related to the data. Any one of part 4 is provided. In this embodiment, the component held by the holding unit 2 is assumed to be a FASA (Flexible Access System Architecture) application, which will be described later. A FASA application is a software component that uses a generalized input/output interface (for example, FASA application API) to implement functions that differ for each service or each carrier. In this embodiment and other embodiments, the components held by the holding unit 2 are software components such as FASA applications. ), hardware such as an external hardware component, or a component including hardware.

Hereinafter, the processing performed by the data processing device 1 will be described by exemplifying a plurality of operation examples (first operation example to sixth operation example).
(First operation example)
As a first operation example, the data processing apparatus 1 sequentially calls components (for example, FASA application) associated with the data contents according to the contents of the data, print the output. Here, a component in the previous order represents a component (for example, a component called for the T-1 time) that was called before the T-th call (the component called this time) by the data processing device 1. .

In the first operation example, the information unit 3 holds a list of processes (hereinafter referred to as a "process list") as information on parts. The processing list associates data processing with a component that performs the data processing. The output unit 4 sequentially calls components (FASA applications) that process the data based on the input data and the processing list, and outputs the data or the components in the previous order to the called components. Here, the data to be output may be all the input data. In this case, since a group of data is collectively transferred to the part, there is an effect that the group of data is not scattered and becomes easy to understand.

Further, the output unit 4 may output only data related to processing to the component without outputting data not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. In particular, the output unit 4 has the effect of reducing the amount of data to be output when actual data is output to the component instead of the index representing the storage location of the data. It is desirable to perform a plurality of processes in parallel by pipeline processing or the like.

Also, the processing list may be separately held in the information unit 3 for each parallel processing, or may be shared by a plurality of processings. When stored separately, it is easy to record the data distribution status for each processing list, and when shared, it is desirable that the information section 3 separately retains a record of the data distribution status for each process. Although the output of actual data has been mainly described here, the output unit 4 indicates information indicating the data storage location (for example, the address of the data storage destination) or indicates the storage location of the output of the components in the previous order. Information may be output and data may be processed on a storage location where each part is identified based on the output information.
The call is exemplified by software components such as the FASA application, but may be the FASA platform (FASA base). The same applies to the following description.

(Second operation example)
As a second operation example, the data processing apparatus 1 sequentially calls a plurality of components (FASA applications) associated with the data contents according to the data contents, and assigns the data or the preceding parts to the called components. print the output. In the second operation example, the information unit 3 holds a list (hereinafter referred to as a "processing chain list") indicating the order in which the processing is performed for the components involved in the processing, as the information regarding the components. The processing chain list associates data processing with components indicated in the order of data processing. Based on the input data and the processing chain list, the output unit 4 sequentially calls the components that process the data, and outputs the data or the output of the components in the previous order to the called components.

Specifically, first, the output unit 4 refers to the processing chain list to identify the component that processes the input data first. Next, the output unit 4 calls the specified part and outputs the data or the output of the previous order part to the called part. When the data processing by the called component is completed, the output unit 4 refers to the processing chain list and specifies the component to process the data next. Next, the output unit 4 calls the specified part and outputs the data or the output of the previous order part to the called part. After that, the output unit 4 repeats the calling of the component and the output of the data or the component in the previous order according to the processing chain list until the processing of the input data is completed.

Here, the data to be output may be all the input data. In this case, since a group of data is collectively transferred to the part, there is an effect that the group of data is not scattered and becomes easy to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. In particular, the output unit 4 has the effect of reducing the amount of data to be output when actual data is output to the component instead of the index representing the storage location of the data. It is desirable to perform a plurality of processes in parallel by pipeline processing or the like.

Also, the processing chain list may be separately held in the information unit 3 for each parallel processing, or may be shared by a plurality of processing. When stored separately, it is easy to record the data distribution status for each processing chain list, and when shared, it is desirable that the information section 3 separately retains a record of the data distribution status for each process. Although the output of actual data has been mainly described here, the output unit 4 indicates information indicating the data storage location (for example, the address of the data storage destination) or indicates the storage location of the output of the components in the previous order. Information may be output and data may be processed on a storage location where each part is identified based on the output information.
The call is exemplified by software components such as the FASA application, but may be the FASA platform (FASA base). The same applies to the following description.

(Third operation example)
As a third operation example, the data processing apparatus 1 performs a predetermined The parts specified in the correspondence table are sequentially called, and the data or the output of the parts in the previous order is output to the called parts. Here, the output source is an external device or ONU or OLT internal or FASA platform or FASA application. In the third operation example, the information unit 3 holds a correspondence table related to processing as information on parts. The correspondence table associates at least one of data processing and data output sources with components that process data. In addition, it is not necessary to be limited to the correspondence table.

The output unit 4 is a component that processes data based on at least one of the history of the data output sources (for example, the last output source, the second from the last and before), the contents of the data, and the correspondence table. (FASA application) are sequentially called, and the data or the output of the preceding component is output to the called component. Specific processing will be described.

(When data output sources and data processing components are associated in the correspondence table) In this case, when data is input, the output unit 4 refers to the correspondence table to Identify the parts associated with the output source. Then, the output unit 4 outputs the data or the output of the previous-ordered parts for the identified parts.

(When the content of the data and the parts that process the data are associated in the correspondence table)
In this case, when data is input, the output unit 4 refers to the correspondence table and identifies the component associated with the content of the input data. Then, the output unit 4 outputs the data or the output of the previous-ordered parts for the identified parts.

(When the data output source, the data content, and the part that processes the data are associated with each other in the correspondence table)
In this case, when the data is input, the output unit 4 refers to the correspondence table and identifies the component associated with both the output source of the input data and the content of the data. Then, the output unit 4 outputs the data or the output of the previous-ordered parts for the identified parts.

Here, the data to be output may be all the input data. In this case, since a group of data is collectively transferred to the part, there is an effect that the group of data is not scattered and becomes easy to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. In particular, the output unit 4 has the effect of reducing the amount of data to be output when actual data is output to the component instead of the index representing the storage location of the data. It is desirable to perform a plurality of processes in parallel by pipeline processing or the like.

Also, the correspondence table may be separately held in the information unit 3 for each parallel process, or may be shared by a plurality of processes. If stored separately, it is easy to record the data distribution status for each correspondence table, and if shared, it is desirable that the information unit 3 separately store a record of the data distribution status for each process. Although the output of actual data has been mainly described here, the output unit 4 indicates information indicating the data storage location (for example, the address of the data storage destination) or indicates the storage location of the output of the components in the previous order. Information may be output and data may be processed on a storage location where each part is identified based on the output information.
The call is exemplified by software components such as the FASA application, but may be the FASA platform (FASA base). The same applies to the following description.

(Fourth operation example)
As a fourth operation example, the data processing apparatus 1 performs a predetermined The parts specified in the correspondence table are sequentially called, and data is output to the called parts. Here, the output source of data is an external device or ONU or inside OLT or FASA platform or FASA application. In the fourth operation example, the information unit 3 holds a correspondence table related to processing as information on parts. The correspondence table associates at least one of data processing and data output sources with components that process data. In addition, it is not necessary to be limited to the correspondence table.

The output unit 4 is a component that processes data based on at least one of the history of the data output sources (for example, the last output source, the second from the last and before), the contents of the data, and the correspondence table. (FASA application) are sequentially called, and the data or the output of the preceding component is output to the called component.

Here, the data to be output may be all the input data. In this case, since a group of data is collectively transferred to the part, there is an effect that the group of data is not scattered and becomes easy to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. In particular, the output unit 4 has the effect of reducing the amount of data to be output when actual data is output to the component instead of the index representing the storage location of the data. It is desirable to perform a plurality of processes in parallel by pipeline processing or the like.

Also, the correspondence table may be separately held in the information unit 3 for each parallel process, or may be shared by a plurality of processes. If stored separately, it is easy to record the data distribution status for each correspondence table, and if shared, it is desirable that the information unit 3 separately store a record of the data distribution status for each process. Forwarding-Engine, SW, or the like may be used as the output unit 4 that transfers data to the component. The use of Forwarding-Engine, SW, etc. is particularly suitable when the data is in a predetermined frame format. Although the output of actual data has been mainly described here, the output unit 4 indicates information indicating the data storage location (for example, the address of the data storage destination) or indicates the storage location of the output of the components in the previous order. Information may be output and data may be processed on a storage location where each part is identified based on the output information. As for the destination (storage destination), when the output unit 4 instructs the next part for each process, it takes time to refer to the Table (correspondence table)/list one by one, but there is no need to convey the destination information to the part, and TAG, which will be described later. has the effect of eliminating the need for
The call is exemplified by software components such as the FASA application, but may be the FASA platform (FASA base). The same applies to the following description.

(Fifth operation example)
As a fifth operation example, the data processing device 1 identifies the data output destination based on the Tag, sequentially calls the identified predetermined parts, and outputs the data or the output of the preceding parts to the called parts. Here, the output source of data is an external device or ONU or inside OLT or FASA platform or FASA application. In the fifth operation example, the output unit 4 identifies the data output destination based on the Tag, sequentially calls the identified predetermined parts, and outputs the data or the output of the preceding parts to the called parts.

The Tag may be given, for example, before inputting the FASA platform or when inputting the FASA platform or a predetermined part (FASA application). A plurality of tag destinations may be assigned sequentially, or may be assigned to each division when data is divided for processing. Tags may be assigned to all destinations, or to a plurality of destinations (for example, up to several destinations). When a plurality of tags are attached, it is desirable that the output unit 4 removes the tags for which the data has already been transferred so that the parts whose data has already been transferred can be identified, or attaches a mark indicating that the data has been transferred.

Here, the output of actual data has been mainly described, but the output unit 4 outputs information indicating the data storage location (for example, the address of the data storage destination, etc.), and based on the output information, each component Data may be processed on the identified storage location. When tags are assigned to parts, it is necessary to transmit information for assigning tags to parts. As a way of communicating, the function (for example, assigning unit) that assigns tags may refer to a list such as a table each time a tag is assigned, a predetermined number of times, or each time a predetermined period of time elapses. FASA application) may be referred to or read at the time of updater such as replacement/addition/deletion of parts (FASA application) or board startup/reboot/liveupdate. It should be noted that the function of assigning tags (for example, an assigning unit) may be provided in the data processing device 1 or may be provided in an external device connected to the data processing device 1 .

In the case of giving in a common part such as SW or CONT version, it is the same as the above that it is transmitted to the place to give. When tags are given by Forwarding-Engine, SW, etc., when replacing/adding/deleting parts (FASA application) in Forwarding-Engine, etc., or when updating parts (FASA application) or base board, rebooting, Liveupdate, etc. It may be set.

Here, the data to be output may be all the input data. In this case, since a group of data is collectively transferred to the part, there is an effect that the group of data is not scattered and becomes easy to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. In particular, the output unit 4 has the effect of reducing the amount of data to be output when actual data is output to the component instead of the index representing the storage location of the data. It is desirable to perform a plurality of processes in parallel by pipeline processing or the like.

Also, the table or list may be separately held in the information unit 3 for each parallel process, or may be shared by a plurality of processes. If stored separately, it is easy to record the data distribution status for each correspondence table, and if shared, it is desirable that the information unit 3 separately store a record of the data distribution status for each process. Forwarding-Engine, SW, or the like may be used as the output unit 4 that transfers data to the component. The use of Forwarding-Engine, SW, etc. is particularly suitable when the data is in a predetermined frame format. Although the output of actual data has been mainly described here, the output unit 4 indicates information indicating the data storage location (for example, the address of the data storage destination) or indicates the storage location of the output of the components in the previous order. Information may be output and data may be processed on a storage location where each part is identified based on the output information.
The call is exemplified by software components such as the FASA application, but may be the FASA platform (FASA base). The same applies to the following description.

(Sixth example of operation)
As a sixth operation example, the data processing apparatus 1 associates data output from an external device, ONU or OLT, FASA platform or component (FASA application) via FASA-API, or an address indicating a storage location of the data. A part (FASA application) corresponding to the Tag performs processing based on the Tag. For example, a component (FASA application) scans the Tag during the processing time assigned to the component, and processes the data to be processed by the component or the output of the component in the previous order.

The Tag may be given, for example, before inputting the FASA platform or when inputting the FASA platform or a predetermined part (FASA application). A plurality of tag destinations may be assigned sequentially, or may be assigned to each division when data is divided for processing. Tags may be assigned to all destinations, or to a plurality of destinations (for example, up to several destinations). When a plurality of tags are attached, it is desirable that the output unit 4 removes the tags for which the data has already been transferred so that the parts whose data has already been transferred can be identified, or attaches a mark indicating that the data has been transferred.

Here, the output of actual data has been mainly described, but the output unit 4 outputs information indicating the data storage location (for example, the address of the data storage destination, etc.), and based on the output information, each component Data may be processed on the identified storage location. When tags are assigned to parts, it is necessary to transmit information for assigning tags to parts.

FASA application) may be referred to or read at the time of updater such as replacement/addition/deletion of parts (FASA application) or board startup/reboot/liveupdate.

In the case of giving in a common part such as SW or CONT version, it is the same as the above that it is transmitted to the place to give. When tags are given by Forwarding-Engine, SW, etc., when replacing/adding/deleting parts (FASA application) in Forwarding-Engine, etc., or when updating parts (FASA application) or base board, rebooting, Liveupdate, etc. It may be set.

Here, the data to be output may be all the input data. In this case, since a group of data is collectively transferred to the part, there is an effect that the group of data is not scattered and becomes easy to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data not processed by the component to the component.

In particular, the output unit 4 has the effect of reducing the amount of data to be output when actual data is output to the component instead of the index representing the storage location of the data. It is desirable to perform a plurality of processes in parallel by pipeline processing or the like.

Also, the table or list may be separately held in the information unit 3 for each parallel process, or may be shared by a plurality of processes. If stored separately, it is easy to record the data distribution status for each correspondence table, and if shared, it is desirable that the information unit 3 separately store a record of the data distribution status for each process.

Information may be output and data may be processed on a storage location where each part is identified based on the output information.
The call is exemplified by software components such as the FASA application, but may be the FASA platform (FASA base). The same applies to the following description.

The data processing device 1 enables the transfer of data between the modules shown in FIG. 8 by performing any one of the first to sixth operations described above. In the above description, the parts (FASA application) provided by the OLT were exemplified, but data delivery may be performed by the software that constitutes the FASA platform, the FASA platform itself, ONUs, other OLTs, and external devices.

The data processing device 1 is, for example, a communication device that executes communication with another communication device using a signal such as an optical signal that passes through a communication network such as an optical fiber network such as a PON. This communication device is, for example, an OLT (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 optical signals and another switch unit (SW). The communication device may be, for example, a combination of an OLT and an ONU (Optical Network Unit). A communication device may comprise multiple devices. Other communication devices such as ONUs, MUXs (multiplexers), DEMUXs (demultiplexers), and switches may also be used.

Next, as an example, the operation etc. will be illustrated on the premise that the communication device as the data processing device 1 is a PON OLT conforming to ITU-T recommendations such as a TWDM (Time and Wavelength Division Multiplex)-PON system. do. Although TWDM-PON is used here, the PON may be a PON other than the TWDM-PON conforming to the ITU-T recommendations. For example, the PON may be an IEEE standard-compliant PON such as GE (Gigabit Ethernet (registered trademark))-PON, 10 GE-PON, or the like. 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.

A communication device comprises components or componentized functions of hardware or software or a combination thereof. For example, the communication device includes an application (eg, FASA application), which is a software component that implements different functions for each service or each carrier using a generalized input/output interface (eg, FASA application API), Fundamental components of access network equipment (e.g., FASA infrastructure) that provide services and functions that do not require changes in response to requests because they are standardized and provide generalized input/output interfaces for the applications. ). Here, by using a generalized input/output interface, it is possible to easily add or replace functions, and to provide various requested services flexibly and quickly. In addition, in this specification, an application is also described as an “application”.

Communication between components is performed, for example, via the middleware unit 120, which will be described later, but it is also possible to use a transfer path or means unique to the communication device, or use OpenFlow, Netconf/YANG, SNMP (Simple Network Management Protocol), or the like. A standardized means of

Further, communication between components may take any route such as internal wiring, backboard, OAM section, main signal line, dedicated wiring, operation system, controller or control panel (Cont panel). When directly terminating exchanges between components and inputting them, they may be encapsulated in the OAM part or the main signal. Communication between components may be terminated at any point and input via a route such as internal wiring, backboard, OAM unit, main signal line, dedicated wiring, operation system, controller or control panel. . When using the OAM part or the main signal line, it is desirable to encapsulate the OAM part or the main signal. When the main signal line is passed through, it is desirable to distribute it by the OSU or a switch section in another place.

In this embodiment, the communication device 51 further comprises an interface for receiving software components in an application such as the FASA application or a platform such as the FASA base.

The interface relates to, for example, lists and tables for data transfer. It is an interface that conveys them as a whole to the part (FASA application) when the part (FASA application) holds them. They are held by the FASA infrastructure, and are interfaces for referencing when a component (FASA application) refers to them. When tags, marks, and address chains are used, it is an interface related to tags that assigns, interprets, or processes tags, marks, and address chains to be used. Also, if the FASA application changes or modifies tags or marks, the interface is for that purpose. Further, the interface is an interface that notifies the destination according to the history when using the progress history of the data component (FASA application).

Embodiment 1-1 describes the configuration of a communication device that constitutes a communication system used for TWDM-PON. The communication device described in Embodiment 1-1 is used as the data processing device 1 shown in FIG. First to sixth examples will be described below as examples of the architecture of the communication device. The architecture of the communication devices that make up the communication system may be an architecture other than the first to sixth examples described below. For example, the software portion of the communication device in the first through sixth architecture examples may be a hardware portion.

(First example of architecture)
FIG. 2 is a diagram showing a first example of architecture of a communication device. In the first example of the architecture, the communication device includes a non-general-purpose device-dependent unit 110 whose operation depends on the device, a middleware unit 120 that hides the difference in hardware and software of the device-dependent unit 110, and a device-dependent unit. and a general-purpose, device-independent application unit 130 that does not Therefore, the device dependent unit 110 (vendor dependent unit) is a functional unit that depends on the standard to which the device of the communication device conforms and the manufacturer of the device. In other words, the device dependent section 110 has little compatibility with other communication devices and cannot be used as is for newly manufactured communication devices (particularly, devices conforming to different standards or manufactured by different vendors). The device dependent unit 110 executes one or more functions provided in the network device.

Also, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device conforms or the manufacturer of the device. In other words, the device-independent application unit 130 is highly compatible with other communication devices, and can be used as-is for newly manufactured communication devices (particularly, devices conforming to different standards and manufactured by different vendors). Specific examples of applications provided in the device-independent application unit 130 include an application that performs setting processing in a network device, an application that performs setting change processing, an application that performs algorithm processing, and the like.

The middleware section 120 and the device independent application section 130 are connected via the device independent API 21 . The device-independent API 21 is a device-independent input/output IF.

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 section 111 (PHY), the hardware section 112 (MAC), the software section 113, the OAM section 114, and the middleware section 120 are connected via the device dependent API 23 .

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.

The type of function to be used as the device dependent section 110 or the device independent application section 130 is determined by limitations derived from the processing for realizing the middleware section 120 and the device independent application section 130, for example, the processing capability of the software. In addition to the restriction to be applied, it may be determined according to the update frequency of the function, the importance of the extended function, and the like. As a result, the communication device can facilitate the flexible and rapid addition of the extended function unit (original function unit) by the device independent application unit 130, and can provide communication services in a timely manner.

For example, the device-dependent unit 110 or the device-independent unit gives priority to functions with high update frequency such as priority processing of main signals and DBA (Dynamic Bandwidth Assignment) that improves line utilization efficiency, or functions that contribute to communication service differentiation. You may decide to use the application unit 130 . Furthermore, the device-independent application section 130 may be the device-independent application unit 130 that has a small difference in at least one of the standards, generations, methods, systems, device types, and manufacturing vendors to which the devices to be shared conform.

Any conforming standard, generation, method, system, device type, and/or manufacturing vendor functionality, even if not optimal for the conforming standard, generation, method, system, device type, and/or manufacturing vendor A common IF for executing functions may be used to generalize the . The common IF may include IFs and parameters that are not used in any of the standards, generations, schemes, systems, device types, and manufacturing vendors that the device dependent unit 110 complies with.

The device dependent section 110 shown in FIG. 2 includes a hardware section 111 (PHY), a hardware section 112 (MAC), and a software section 113 . The hardware unit 111 (PHY) executes processing from the physical layer to optical transmission/reception-related processing (PHYsical sublayer processing). The hardware unit 112 (MAC) executes MAC (Media Access Control) processing. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) depend on conforming standards and manufacturing vendors. The software unit 113 executes device-dependent drivers, firmware, applications, and the like.

The hardware section 111 (PHY) and the hardware section 112 (MAC) of the device dependent section 110 may also include a general-purpose server, a layer 2 switch, and the like. The device dependent unit 110 does not have to include the hardware unit 112 (MAC). The device dependent unit 110 does not have to include part of the hardware unit 111 (PHY). For example, the device-dependent unit 110 may have only optical-related functions without low-level signal processing such as modulation/demodulation signal processing, forward error correction (FEC), coding/decoding processing, and encryption processing. good. The device dependent unit 110 does not have to include a PCS (PHYsical Coding Sublayer) that encodes data. The device dependent unit 110 does not have to include a PMA (Physical Medium Attachment) and a PCS that serialize data. The device dependent unit 110 may not have a PMD that connects to a physical medium. When the device dependent unit 110 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 middleware unit 120 going through the software unit 113, The software section 113 may not be provided.

The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 (extended function A, extended function B, and extended function C in FIG. 2), a basic function unit 132, and a management/control agent unit. 133. The management/control agent unit 133 exchanges data from an EMS (Element Management System) 140 .

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

Hereinafter, items common to the extended function units 131-1 to 131-3 will be referred to as "extended function unit 131" by omitting part of the reference numerals. EMS 140 is, for example, the controller of the NE. Note that the device-independent application unit 130 may not include any one of the extended function unit 131, the basic function unit 132, and the management/control agent unit 133, and the management/control agent unit 133 may , 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 section 130 may further include components other than the extended function section 131 , basic function section 132 , and management/control agent section 133 . For example, if the extended function section 131 is unnecessary, the device independent application section 130 may not include the extended function section 131 . Also, the device-independent application unit 130 may include one or more extended function units 131 .

It is preferable that the extended function part 131 can be added, deleted, replaced or changed independently 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 for executing a multicast service or power saving correspondence becomes necessary in accordance with service requirements. .

The basic function unit 132 may be included in the device-independent application unit 130 as part of the extended function unit 131 or may be replaced by a function unit lower than the middleware unit 120 . If the extended function part 131 includes the basic function part 132 , the device independent application part 130 does not have to include the basic function part 132 . When a functional unit lower than the middleware unit 120 replaces the basic functional unit 132 , the device independent application unit 130 may not include the basic functional unit 132 . If the extended function unit 131 includes the basic function unit 132 and a lower-level function unit 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 with the EMS 140 when performing automatic setting according to predetermined settings without receiving communication from the EMS 140 . Furthermore, when the management/control agent unit 133 does not have a management setting function, and the other device independent application unit 130, the basic function unit 132, or the device dependent unit 110 has a management setting function, the device independent application unit 130 The management/control agent unit 133 may not be provided.

EMS 140 and device independent application unit 130 may directly input/output information. Further, the device dependent unit 110 may be replaced by the NE management/control unit 115 and the device dependent application unit 150 (see FIG. 3 and FIG. 5 described later), which is a lower functional unit of the NE management/control unit 115. good.

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

An example of input/output between the device independent application section 130 and the device dependent section 110 is as follows.
For example, the DBA application section and the protection application section mutually input/output information with the Embedded OAM Engine of the TC layer. A DWBA (Dynamic Wavelength and Bandwidth Assignment) application and an ONU registration authentication application part 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 (Multicast Listener Discover) proxy application unit inputs and outputs information to and from the L2 function unit. The Low Speed Monitoring App (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functions operate the XGEM Framer (XGPON Encapsulation Method Framer) and encryption. Here, DWBA and DBA may be separate, integrated or combined. For example, the management/control agent unit 133 is an application unit for maintenance and operation functions, and exchanges information with the EMS 140, which is an NE controller for the NE management/control unit 115, and the like.

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

The device-independent application unit 130 is used for device vendor, system, device type, device generation, for example, ITU-T G.2000. TWDM-PON conforming to ITU-T G.989 series and ITU-T G.989 series. XG-PON conforming to ITU-T G.987 series and ITU-T G.987 series. G-PON conforming to the 984 series and ITU-T G.984 series. It is an application that operates independently of B (Broadband) PON conforming to the 983 series. The device-independent application unit 130 determines the device vendor, method, device type, device generation, for example, the difference between 10GE-PON conforming to IEEE802.3av, IEEE1904.1, etc. and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of

As an application of the extended function unit 131, an application for driving functions provided for some vendors, methods, types, and generations, and only devices for some vendors, methods, types, and generations, via the device-independent API 21. may include apps that drive functionality 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 transmit/receive NE management information and control information directly to/from the EMS 140 without going through the middleware unit 120, or may transmit/receive NE management information and control information through the management/control agent unit 133. You can send and receive.

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

At the time of input, the middleware section 120 deletes unnecessary input information for each input destination, and if there is insufficient information, it can collect and supplement it via other device-independent APIs 21 and device-dependent APIs 23 . desirable. Also, when inputting to the middleware unit 120, it may be broadcast or multicast to be sent to related applications or the like.

In FIG. 2, the middleware section 120 and the device dependent section 110 are illustrated as a single unit, but each of them may be composed of a plurality of units. If the hardware of the device dependent unit 110 includes a plurality of processors, the middleware unit 120 may input/output data across processors and hardware using interprocessor communication or the like. Between the device-independent application units 130 and the device-independent application units 130 may be arranged in the 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 placed in user space.

In addition, the device-independent application section 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 section 120 having an IF that can be replaced independently such as firmware. Alternatively, it may be incorporated into firmware or the like and recompiled. Any combination of user space and kernel space may be used for each device-independent application unit 130 .
The device independent application section 130 corresponding to the same function may be implemented in both the user space and the kernel space. In this case, for example, one of them may be selected by switching, both may be processed in cooperation with each other, or actual processing may be performed by only one of them. The software of the device dependent part 110 is the same.

Desirably, as high-speed processing as main signal processing, DBA processing, and low-layer signal processing is required, high-speed processing with little overhead is expected, although there is a trade-off between scalability and immediacy of replacement. It is preferable to embed it in kernel space or firmware. The processor in which the device-dependent application unit 150 (see FIG. 3 and FIG. 5 to be described later) is arranged should also be implemented from the viewpoint of bus and speed restrictions due to inter-processor communication, and the impact on other programs due to occupation of the communication channel, etc. It is desirable to place it in the user space, kernel space, or firmware of the processor that performs the processing or its neighboring processor. However, in order to reduce the capacity of the processor that performs the actual processing or the processor in the vicinity thereof, the communication cost due to inter-processor communication increases, but processing may be performed by a remote processor.

The device-independent API 21 is desirably provided in advance in the middleware section 120 in anticipation of the extended function section 131 to be added. may be added or deleted accordingly.

In this example, the software areas are the basic function part 132, the management/control agent part 133, the extended function part 131, and the middleware part 120, but the software area is service adaptation (encryption, fragment processing, GEM Framing/XGEM framing, PHY adaptation FEC, scrambling, sync block generation/extraction, GTC (GPON Transmission Convergences) framing, PHY framing, SP conversion, and coding schemes.Architecture softening function An implementation example and an example of function deployment corresponding to the hardware unit will be described.Function deployment includes, for example, a software function in a network device or an external server.This is the same for other examples.

It is preferable that the extended function part 131 can be added or deleted independently without affecting other functions. For example, when the extended function unit 131 is used for multicast services and power saving according to service requirements, the extended function unit 131 is added as necessary, and deleted as unnecessary. and may be replaced or changed accordingly.

The device-independent API 22 is preferably provided in advance in the basic function unit 132 in anticipation of the extended function unit 131 to be added later. It may be added or deleted in such a way that modification of the dependent application unit 130 is suppressed.

(Fourth example of architecture)

The difference between the fourth example of architecture and the third example of architecture is that the communication device includes a device-dependent application section 150 under the basic function section 132 . In this way, the communication apparatus of the fourth example of architecture has the effect of simplifying the configuration of the basic function section 132 by including the device-dependent application section 150 .

The communication device shown in FIG. 5 includes a device dependent section 110 and a device independent application section 130 . The device-dependent unit 110 includes a hardware unit 111 (PHY) and a hardware unit 112 (MAC) that depend on a conforming standard or a device manufacturing vendor, and a hardware unit 111 (PHY) and a hardware unit 112 (MAC). It has a software section 113 such as a driver and firmware for driving, and a device dependent application section 150 for driving at least part of the device dependent section 110 . The device-independent application unit 130 connects the porting IF with the device-dependent application via a driver that hides the difference between the porting IF and the hardware unit 111 (PHY), and the hardware unit 112 (MAC) with the device-dependent software. It is a general-purpose, device-independent application that executes device-independent processing via the unit 150 . The basic function section 132 within the device independent application section 130 and the device dependent application section 150 within the device dependent section 110 are connected via the device independent API 27 . The device dependent application section 150 and other functional sections of the device dependent section 110 are connected via the device dependent API 24 .

A basic function unit 132 in the device independent application unit 130 performs input/output with hardware and an extended function unit 131 instead of the middleware unit 120 . A management/control agent unit 133 (see FIGS. 2 and 3) that receives communication from the EMS 140 may be included in the basic function unit 132, and the management/control agent unit 133 is provided as the extended function unit 131. may

The device-independent application unit 130 does not have to include either the extended function unit 131 or the basic function unit 132, as in the third example of the architecture. The device-independent application unit 130 may further include functional units 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 extended function units 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 with the device-dependent application unit 150 . Although the device-dependent application unit 150 directly inputs and outputs information from the basic function unit 132, it is possible to input and output information to and from the EMS 140 directly or after predetermined conversion without going through the basic function unit 132. good.

(Fifth example of architecture)
The upper right diagram of FIG. 6 is a diagram showing a fifth example of the architecture. The lower right diagram of FIG. 6 corresponds to the first to fourth examples of architecture. The figure shows a case where the communication device is an OLT. The fifth example of architecture is a function cloud that prepares addition/modification of functions according to services by implementing OLT functions on external hardware (cloudization), utilizing existing/off-the-shelf OLT hardware. It is suitable when performing a conversion approach.

In this example, the communication device consists of off-the-shelf/off-the-shelf hardware and external hardware. For example, existing/off-the-shelf hardware is a device-dependent non-general-purpose device-dependent unit 110, a middleware unit 121 that hides differences in hardware and software on external hardware, and a general-purpose unit whose operation does not depend on the device. device independent application unit 130. Therefore, the device-dependent part (vendor-dependent part) below the middleware in FIG. 10 is a functional part that depends on the standard to which the device of the communication device complies and on the manufacturer of the device. Also, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device conforms or the manufacturer of the device.

The middleware section 121 and the device-independent application section 130 are connected via a device-independent API, which is an input/output IF that is device-independent. The device-dependent unit 110 includes, for example, a software unit, an OAM, a hardware unit (PHY) and a hardware unit (MAC), and a middleware unit 121 on external hardware. Connected via APIs and machine-to-machine connections between existing/off-the-shelf hardware and external hardware.

This architecture facilitates flexible and rapid addition of extended function units (original function units) by the device-independent application unit 130, and can provide communication services in a timely manner. Here, the device dependent unit 110 may be the maintenance operation, access control, physical layer processing, and optical modules shown in FIG. 6, depending on the configuration of the device itself.

For example, the device dependent unit 110 or the device independent application unit 130 is given priority to a function that has a high update frequency such as DBA that improves the priority processing of the main signal and line utilization efficiency, or a function that contributes to communication service differentiation. You can decide. Furthermore, the device-independent application section 130 may be the device-independent application unit 130 that has a small difference in at least one of the standards, generations, methods, systems, device types, and manufacturing vendors to which the devices to be shared conform.

Any conforming standard, generation, method, system, device type, and/or manufacturing vendor functionality, even if not optimal for the conforming standard, generation, method, system, device type, and/or manufacturing vendor A common IF for executing functions may be used to generalize the . The common IF may include IFs and parameters that are not used in any of the standards, generations, schemes, systems, device types, and manufacturing vendors that the device dependent unit 110 complies with.

A conversion function unit that converts IF, parameters, etc. 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) so as to correspond to the device dependent unit 110. Alternatively, a function unit for automatically setting corresponding to insufficient IF, parameters, etc. may be further provided.

The device dependent section 110 includes a hardware section and a software section. The software section executes device-dependent drivers, firmware, applications, and the like.

The device dependent unit 110 does not have to include the PMD and MAC that connect to the physical medium, the PMA that serializes data, and the PCS or PHY that encodes data. For example, only optical-related functions may be provided without low-level signal processing such as modulation/demodulation signal processing, forward error correction (FEC), encoding/decoding processing, and encryption processing.

The device-independent application section 130 includes, for example, a management/control agent section 133 that acquires data from the EMS, extended function sections 131-1 to 131-3, and a basic function section 132. FIG. Hereinafter, items common to the extended function units 131-1 to 131-3 will be referred to as "extended function unit 131" by omitting part of the reference numerals. An EMS is, for example, a controller that controls network elements. Note that the device-independent application unit 130 does not have to include any one of the management/control agent unit 133 , the extended function unit 131 and the basic function unit 132 .

The device independent application section 130 may further include components other than the management/control agent section 133 , the extended function section 131 and the basic function section 132 . For example, if the extended function section 131 is unnecessary, the device independent application section 130 may not include the extended function section 131 . Also, the device-independent application unit 130 may include one or more extended function units 131 .

It is preferable that the extended function part 131 can be added, deleted, replaced or changed independently 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 for executing a multicast service or power saving correspondence becomes necessary in accordance with service requirements. .

The basic function unit 132 may be included in the device-independent application unit 130 as part of the extended function unit 131 or may be replaced by a lower-level function unit than the middleware unit 121 . If the extended function part 131 includes the basic function part 132 , the device independent application part 130 does not have to include the basic function part 132 . When a functional unit lower than the middleware unit 121 replaces the basic functional unit 132 , the device-independent application unit 130 may not include the basic functional unit 132 . If the extended function unit 131 includes the basic function unit 132 and a lower-level function unit 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 with the EMS 140 when performing automatic setting according to predetermined settings without receiving communication from the EMS 140 . Furthermore, when the management/control agent unit 133 does not have a management setting function, and the other device independent application unit 130, the basic function unit 132, or the device dependent unit 110 has a management setting function, the device independent application unit 130 The management/control agent unit 133 may not be provided.

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

The basic function unit 132 may be included in the device-independent application unit 130 as part of the extended function unit 131 or may be replaced by a lower-level function unit of the middleware unit 120 . When the extended function part 131 includes the basic function part 132, when the lower function part of the middleware part 120 substitutes for the basic function part 132, or when they are a combination thereof, the device-independent application part 130 does not include the basic function part. 132 may not be included. Also, 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/output information to/from the EMS 140 when performing automatic setting according to predetermined settings. Furthermore, when the management/control agent unit 133 does not have a management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 does not have a management setting function, the device-independent application unit 130 does not have a management setting function. - The control agent unit 133 may not be provided. EMS 140 and device independent application unit 130 may directly input/output information.

An example of input/output between the device independent application section 130 and the device dependent section 110 is as follows. For example, the DBA application part and the protection application part input/output information to/from the embedded OAM engine of the TC layer. The DWBA application and the ONU registration authentication application part exchange 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 inputs and outputs information to and from the L2 function unit. The Low Speed Monitoring App (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functions run the XGEM framer and encryption. Here, DWBA and DBA may be separate, integrated or combined. For example, the management/control agent unit 133 is an application unit for maintenance and operation functions, and exchanges information with the EMS 140, which is an NE controller for the NE management/control unit 115, and the like.

The device-independent application unit 130 is used for device vendor, system, device type, device generation, for example, ITU-T G.2000. TWDM-PON conforming to ITU-T G.989 series and ITU-T G.989 series. XG-PON conforming to ITU-T G.987 series and ITU-T G.987 series. G-PON conforming to the 984 series and ITU-T G.984 series. It is an application that operates independently of BPON that conforms to the 983 series. The device-independent application unit 130 determines the device vendor, method, device type, device generation, for example, the difference between 10GE-PON conforming to IEEE802.3av, IEEE1904.1, etc. and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of

As an application of the extended function unit 131, an application for driving functions provided for some vendors, methods, types, and generations, and only devices for some vendors, methods, types, and generations, via the device-independent API 21. may include apps that drive functionality 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 transmit/receive NE management information and control information directly to/from the EMS 140 without going through the middleware unit 120, or may transmit/receive NE management information and control information through the management/control agent unit 133. You can send and receive.

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

At the time of input, the middleware section 120 deletes unnecessary input information for each input destination, and if there is insufficient information, it can collect and supplement it via other device-independent APIs 21 and device-dependent APIs 23 . desirable. Also, when inputting to the middleware unit 120, it may be broadcast or multicast to be sent to related applications or the like.

Although the middleware section 120 and the device dependent section 110 are single in the example, they may be configured in plural. If the hardware of the device dependent unit 110 includes a plurality of processors, the middleware unit 120 may input/output data across processors and hardware using interprocessor communication or the like. Between the device-independent application units 130 and the device-independent application units 130 may be arranged in the user space on a single processor as an execution program such as a DLL, or in the user space on a plurality of processors. You may

In addition, the device-independent application section 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 section 120 having an IF that can be replaced independently such as firmware. Alternatively, it may be incorporated into firmware or the like and recompiled. Any combination of user space and kernel space may be used for each device-independent application unit 130 .

The device independent application section 130 corresponding to the same function may be implemented in both the user space and the kernel space. In this case, for example, one of them may be selected by switching, both may be processed in cooperation with each other, or actual processing may be performed by only one of them. The software of the device dependent part 110 is the same.

Desirably, as high-speed processing as main signal processing, DBA processing, and low-layer signal processing is required, high-speed processing with little overhead is expected, although there is a trade-off between scalability and immediacy of replacement. It is preferable to embed it in kernel space or firmware. The processors in which the device-dependent application section 150 is arranged are also restricted from the viewpoint of bus and speed restrictions due to inter-processor communication, and from the viewpoint of influences on other programs due to occupation of communication channels, etc. or kernel space or firmware. However, in order to reduce the capacity of the processor that performs the actual processing or the processor in the vicinity thereof, the communication cost due to inter-processor communication increases, but processing may be performed by a remote processor.

For example, only the PON main signal processing function, PON access control function, L2 main signal processing function, and maintenance operation function may be provided, or other functions may be provided. may Also, the evaluation of whether or not each function can be made softer is an example based on the premise that the OLT processing capacity is expected in 2018 and the application of soft switches is not assumed. It may be changed as appropriate, assuming the assumed processing capacity and the application of the soft switch. Even if it is a function that can be softened, it does not have to be softened. The internal configuration of each function may be any other configuration as long as the same functions can be realized.

Algorithms included in the eight main functions are the main softening areas. It is assumed that the function in the software area is the device independent application section 130 on the device independent APIs 21 and 22 . For example, algorithms in the ONU registration or authentication function, DWBA function, setting/management/monitoring control function, and power saving control function that contribute to differentiated services are treated as the extended function section 131 in the device independent application section 130 . The MLD Proxy App includes multicast functionality.

Among applications, the extended function unit 131 is selected depending on the degree of importance such as the update frequency of functions and the realization of unique specifications. Those that have a low update frequency or a low demand for implementation of unique specifications are the middleware section 120 other than the basic function section 132 and the device independent application section 130, device dependent software, hardware section 111 (PHY) and hardware section 112 ( MAC). In particular, it is preferable to leave the functions restricted by the processing capability of the software in the hardware section 111 (PHY) and the hardware section 112 (MAC). For example, priority processing of main signals, functions that contribute to service differentiation, such as DBA that improves line utilization efficiency, and functions that contribute to service differentiation, and management that is closely related to operator's business flow and requires unique specifications for each operator The extended function unit 131 starts from the control function.

FIG. 20 is a diagram illustrating an example of architectural details of a communication device. The embedded OAM engine 114 a (Embedded OAM Engine) is connected to the DBA application section and the protection application section via the middleware section 120 . The PLOAM engine 114b is connected via the middleware unit 120 to the DWBA application, ONU registration authentication, high-speed monitoring application, power saving application and protection application.

OMCI is connected to the power saving application and low speed monitoring application (OMCI) via the middleware unit 120 . The L2 function unit (L2 function) is connected to the power saving application and the MLD proxy application via the middleware unit 120 . The L2 function unit is further connected to the setting/management application via the middleware unit 120 . The NE management unit 115a is connected to a setting/management application. The NE control 115b is connected to a low speed monitoring application (EMS-IF).

FIG. 21 is a diagram showing the flow of signals/information between functional units within a communication device. This figure shows the flow of signals/information between functional units in the communication device, focusing on the In/Out of the OLT. As shown in the figure, the OLT as a communication device consists of an API lower processing entity (FASA platform) and an application (FASA application).

The API lower processing entities are MPCP/DBA processing entities whose OLT input/output targets are transmission instructions and reception notifications for MPCP transmission/reception, OAM processing entities whose OLT input/output targets are OAM transmission/reception, and OLT input/output targets whose ONU authentication transmission/reception is. 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 other protocol transmission/reception, OLT input/output is main signal processing such as bridging and encryption A main signal setting processing entity for setting, referring to, and acquiring the status of the device, and a device management processing entity for which the OLT input/output target is the OLT hardware, IF, OS, etc. are illustrated. Here, the transmission instruction and reception notification for MPCP transmission/reception are desirably such as send_frame(*raw_frame); assuming that the driver is directly hit.
In the figure, DBA, ONU management, line management, multicast, EtherOAM, redundancy, device management, alarm management, Netconf agent, and application management are exemplified as applications.

In/Out of the OLT is roughly divided into input/output with respect to the ONU, setting/notification to the OLT itself, and input/output with the EMS. From the viewpoint of the application on the upper side of the API, it is (a) easier (convenient) and (b) common (among multiple types) for the lower API processing section compared to processing such as directly hitting the driver. and (c) it is desirable to have a processing entity that conveniently handles it.

Below is an example of the functional division of the API lower processing entities. The app has corresponding processing. The function allocation between the API lower processing entity and the application may be any of the following or other than that, and may differ for each processing entity.

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

(1) Framing: Messages are deframed, decomposed or processed into elements as necessary, and provided to the API upper side. Information is passed from the upper part of the API to the lower part of the API. The API lower processing entity does the framing. Since the API is highly dependent on each protocol, it may be included in the device-dependent application section. Fixed parameters (such as type values) are preferably set and retained at the time of initialization from the top of the API. Setting parameters are returned in response to references from the top of the API.

(2) Automatic response: The processing entity is in charge of sending and receiving messages that do not require judgment, such as regular transmission and fixed response. It is desirable to set the operation in advance from the upper part of the API. For example, response period. The result is notified only when it is necessary to notify the upper part of the API.

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

Although this diagram is described in conformity with IEEE-compliant 10GEPON, if the corresponding functions and processes are reread, the same applies to devices conforming to ITU-T and others. Also, the functions and actual processing are examples, and may be added, deleted, replaced, or changed according to the conditions.

FIG. 22 is a diagram illustrating an example of an application executed by a communication device; CPU processing is classified into three groups. The three groups are Cont-oriented CPUs, OSU-oriented CPUs, and SW-oriented CPUs. Cont-oriented CPU processing is processing for executing a low speed monitoring application (OMCI), a low speed monitoring application (EMS-IF), and a setting/management application. The SW-oriented CPU process is the process of executing the MLD proxy application. The processing of the OSU-oriented CPU is the processing of 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 part of the EMS-IF, or may be equivalent to the device dependent API 25.

In this example, each application is processed by the CPU on the CPU package. In FIG. 22, each application is directed to a control package (Cont. in FIG. 22), which is a control unit in the OLT, to an OSU package (OSU in FIG. 22) equipped with a plurality of optical transceivers (λCard in FIG. 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, protection application, high speed monitoring application, DBA application, DWBA application, and ONU registration authentication application, the SW group is an MLD proxy application, and the Cont group is a low speed monitoring application (OMCI) and a low speed monitoring application (EMS- IF), a setting management application. Furthermore, centralized control by the CPU is assumed, but applications of each classified group may be distributed and arranged in respective packages (Cont, OSU, SW). Alternatively, it may be arranged on any one of Cont, OSU, and SW, or a combination of a plurality of them, regardless of the above classification. Also, the device setting IF in FIG. 22 may be a part of the EMS-IF, or may be equivalent to the device dependent API 25 in FIG. In addition, although the processing of the application is performed on the CPU, part or all of the processing may be performed on a substitute having a processing function, for example, a processor such as a GPU, NPU, or DSP other than the CPU, or an FPGA. The same applies to other embodiments.

FIG. 23 shows an example in which an application is placed on a server or the like instead of a CPU package. An application is processed on a server or the like, and the processing result of the application arrives at the OLT after being transmitted over the transmission line in a format such as an Ethernet (registered trademark) frame that can be transmitted over the transmission line. Here, the format that can be transmitted through the transmission line may be a frame other than the Ethernet (registered trademark) frame, TDM, or the like. Also, the processing result is transmitted via a converter (Conv. in FIG. 23). No machine needed. The server or the like may correspond to the external server 16 in FIG. 7 or may correspond to the proxy unit 15 .

FIG. 24 is a diagram showing an example of functions (processing) of the CPU, switch unit (SW), and OSU. The CPU executes the power saving control function and the protection function by the application. The CPU further includes a maintenance operation function (Fault Management), a maintenance operation function (GTC/PMD config), a PON access processing function (ONU activation), a PON access processing function (DBA), and a PON access processing function (λ allocation change), maintenance operation function (Service Management), and maintenance operation function (Equipment Management). Furthermore, the CPU executes a maintenance operation function (Fault Performance Management) and a multicast function (MLD) by an application.

The switch (SW) has an L2 signal processing function (VLAN), an L2 signal processing function (QoS, Quality of Service), an L2 signal processing function (Mux/DMux, XC, Cross Connect), and a multicast function (Copy). is executed by the app. The OSU MAC executes a PON main signal processing function (Security), a PON main signal processing function (Framing), a PON main signal processing function (FEC), and a frequency/time synchronization function by means of applications.

In FIG. 24, the CPU encloses an example of processing in the basic function unit 132 and unique functions, and the MAC of OSU indicates an example of processing in a vendor-dependent portion, but the classification is not limited to this. The CPU shown in FIG. 25 may be the CPU package shown in FIG. 23, the server shown in FIG. The OSU MAC is assumed to be a dedicated LSI for OSU processing, but a general-purpose LSI may be used if equivalent processing is possible.

FIG. 25 shows the application processing of eight main functions and G. 1 is a diagram showing an example of correspondence with G.989.3 functions; FIG. The DBA app, DWBA app, ONU registration authentication app, power saving app, protection, and high speed monitoring app are connected to the TWDM TC functions of the TWDM TC layer. The MLD proxy is connected with the L2 function. The L2 function is connected with the User Data Client. The setting/management application, the low speed monitoring application (OMCI), and the low speed monitoring application (OSS-IF) are connected to the L2 function. The setting/management application, the low speed monitoring application (OMCI), and the low speed monitoring application (OSS-IF) are further connected to the OMCI client.

FIG. 26 is a diagram showing an example of a configuration for acquiring PLOAM and OMCI via SW. That is, FIG. 26 shows a process in which PLOAM and OMCI acquire corresponding data via SW from the control unit 14 or proxy unit 15 or external server 16 in FIG. 7 in addition to user data.

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

The PLOAM processor of the CPU obtains data from the "AMCC PHY adaptation and framing section" via the switch section. The PLOAM processor of the CPU sends data to the "AMCC PHY adaptation framing unit" via the switch unit. Also, the PLOAM processor of the CPU acquires data from the PLOAM partition via the switch. The PLOAM processor of the CPU sends data to the PLOAM partition unit via the switch unit.

The TWDM TC functions of the TWDM TC layer acquire data from the Embedded header fields via the switch unit. The TWDM TC functional part of the TWDM TC layer transmits data to the embedded header area via the switch part.

In the examples of FIGS. 2 and 3, the softening areas are the basic function part 132, the management/control agent part 133, the extended function part 131, and the middleware part 120, but the softening area is the service adaptation (encrypted , fragment processing, GEM framing/XGEM framing, FEC of PHY adaptation, scrambling, sync block generation/extraction, GTC (GPON Transmission Convergences) framing, PHY framing, SP conversion, and coding schemes may also be targeted. An implementation example of architecture software functions and an example of function deployment corresponding to the hardware unit 111 (PHY) and hardware unit 112 (MAC) will be described.The function deployment is performed by, for example, softwareizing a network device or an external server. It has functions.

Assume an OLT with multiple OSUs, switches, information processors and controllers. Each OSU has a different transceiver for each wavelength. In this case, the middleware section 120 is installed in each OSU and switch, and the software area such as the device independent application section 130 is installed in the information processing section.

The information processing section, that is, the CPU, executes the device independent application section 130 . Device-independent application section 130 includes extended function section 131 for OSU, extended function section 131 for switch, and extended function section 131 for control section. The extended function unit 131 for OSU is, for example, a power saving application, a protection application, a DBA application, and an ONU registration authentication application. The extended function unit 131 for switch is, for example, an MLD proxy application. The extended function unit 131 for the control unit is, for example, a low speed monitoring application (OMCI), a low speed monitoring application (EMS-IF), and a setting/management application. EMS is, for example, OSS (Operation Support System).

G. In the case of 989.3, for example, it becomes as shown in FIGS. In the case of the DBA application, the middleware section 120 shown in FIGS. 2 and 3 or the basic function section 132 shown in FIGS. Run the OAM engine (Embedded OAM Engine). Then, the transmission/reception units, which are the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the PMD layer, receive according to the DBA application. Note that when the transmitting/receiving unit receives an uplink signal that does not comply with DBA, it may not comply with the DBA application.

The information processing section is not limited to these softening functions, and may have other softening 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 the transmitting/receiving unit, OSU, switch, and control unit. Further, as shown in FIG. 7, the NNI (Network-Network Interface) side of the switch may be provided with a proxy unit or an external server for processing signals input/output to/from the switch. The external server 16 may be an information processing function called a so-called cloud such as a data center equipped with a plurality of devices.

Each function may be appropriately arranged according to the processing capacity and processing delay requirements. Also, the OSU may include the switch section 12 or the switch section 13, or may include a switch (the switch section 12 when the switch section 13 is provided) separately from the switch. Although it is desirable that the functions of the switches are not duplicated between the switch section 12 and the switch section 13 and are appropriately shared according to the processing capacity of the switches, they may be duplicated.

The place where the softening function is provided is not limited to the information processing section, and may be placed in a plurality of places where arithmetic processing is possible. For example, the locations where the software function is provided are the transmission/reception unit, the OSU switch, other than the OSU switch, the OLT control unit, the OLT switch, the OLT information processing unit, the OLT switch, the control unit, and the information processing unit, 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.

Further, the softening function may be arranged for each softening function, or may be a part of the softening function obtained by dividing a single softening function. For example, regarding the transmission/reception unit, other parts than the transmission/reception unit, such as OSU switch, OSU transmission/reception unit and other than switch, OLT switch, OLT control unit, OLT information processing unit, OLT other than OLT, Outside the OLT, it may be deployed somewhere in the path of the main signal, such as a proxy section or an external server, or in a combination of multiple deployment locations. Other places other than the PON termination processing installation place, for example, 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 , the OLT, a proxy unit on the main signal path outside the OLT, an external server, or the like, or in a combination of multiple deployment locations.

Regarding the ONU switch, other parts than the ONU switch, for example, the transmitting/receiving section, the OSU transmitting/receiving section other than the switch, the OLT switch, the OLT control section, the OLT information processing section, the OLT other than the OLT, and the OLT external to the main signal path, such as a proxy unit, an external server, etc., or a combination of multiple deployment locations. Other parts other than the OLT switch, for example, the transmitting/receiving section, the OSU switch, the OSU transmitting/receiving section and other than the switch, the OLT control section, the OLT information processing section, the OLT other than the OLT, and the OLT external to the main signal path, such as a proxy unit, an external server, etc., or a combination of multiple deployment locations.

Further, the location where the software function is provided may be appropriately changed according to the deployment status of the extended function unit 131, the computing power, computational load, power consumption, etc. of the location where computation is possible.

The main functions related to the main signal processing of the OLT and the relationship between the functions will be explained. Migrate 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. PON access control functions such as ONU registration or authentication functions, DBA control functions, and DWA functions are provided in the information processing unit. L2 main signal processing functions such as VLAN control, pre-shaper priority control, Mux/DMux and Queue, and pre-framing shaper are deployed in the switch.

A copy function preceding the shaper and a multicast function such as an MLD proxy used for copying are provided in the switch. In this way, the PON basic function unit is reduced by providing the PON main signal processing function and the PON access control function, which have been provided in the PON, in the switch. In particular, the L2 main signal processing should be avoided duplication and preferably located in the switch.

Note that the example assumes that the functions of the switch are provided in the order of Classifier, Modifier, Policer/Shaper, Cross Connect, Queue, and Scheduler. However, it may be changed as appropriate. For example, in the upstream direction, if 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 may be terminated, and all the functions of Classifier, Modifier, Policer/Shaper, Cross Connect, Queue, and Scheduler may be implemented in the switch, or only Modifier, Cross Connect, Queue, and Scheduler may be implemented in the switch.

Furthermore, if a VID or the like describing a path or the like after the PON termination is given by the ONU, Cross Connect, Queue, and Scheduler can be performed. If the upper network can be regarded as a single path, Queue and Scheduler will suffice. Further, if DBA is performed so that frames do not collide in Cross Connect, Classifier, Modifier, Policer/Shaper, and Cross Connect can be used. Furthermore, in the upstream direction, if processing is not performed in the band 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 terminated, and VID or the like describing the path after the PON termination is given by the ONU, it is also possible to have only Cross Connect.

In addition, Classifier, Modifier, Policer/Shaper, Cross Connect, Queue, and Scheduler may be used as Classifier, Policer/Shaper, Modifier, Cross Connect, Queue, and Scheduler. Modifier, Queue, Policer/Shaper, Cross Connect, Scheduler, or Classifier, Queue, Policer/Shaper, Modifier, Cross Connect, Scheduler may be used. Considering the burst transmission of PON, unnecessary policing / shaping due to burstiness caused by multiplexing priority traffic such as multicast, and reception of leveled traffic on the receiving side, policer / shaper It is desirable to place a Queue in the preceding stage and execute processing by Policing/Shaping after leveling.

At the time of state transition to a specific state, the subject of the sleep operation etc. stores the instruction of the subject of the sleep operation etc. (equipment included in the communication device) externally independent of the subject of the sleep operation etc. Actions can be inherited. Specific states are, for example, a sleep state, a switching state of an 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 loss of inheritance such as sleep operation when switching to another communication device. The communication device can ensure inheritance of information held by the device.

In addition, by using a generalized, softwareized switch as an execution unit, it is possible to realize an OLT capable of inexpensively, flexibly, and quickly adding functions to the generalized, softwareized switch.

The configuration according to the embodiment 1-1 shown above is the same in the following embodiments, and may be combined as appropriate. For example, FIG. 2 exemplifies a case where the configuration of the execution unit of the present system is only the transmission/reception unit 11 (TRx), the switch unit 12, and the switch unit 13. A location other than 13, a location other than that, a location where the PON terminates, or the control unit 14 may be the execution unit.

(Embodiment 1-2)
Although the configuration used for TWDM-PON is exemplified in Embodiment 1-1, it may be applied to TDM-PON. TDM-PON is the same as Embodiment 1-1 except that it is not necessary to have a function for wavelength division multiplexing of wavelength resources in the PON section of ONU-OLT between ONUs, such as λ setting switching (DWA). is.

(Embodiment 1-3)
Although the configuration used for TWDM-PON is exemplified in Embodiment 1-1, it may be applied to WDM-PON. Embodiment 1-3 is similar to Embodiment 1-1 except that WDM-PON does not need to have a function such as DBA to time-division multiplex bandwidth resources in the PON section of ONU-OLT between ONUs. is similar to

(Embodiment 1-4)
This embodiment is a combination including OFDM (Orthogonal Frequency Division Multiplex)-PON, CDM (Code Division Multiplex)-PON, SCM (Subcarrier Multiplex)-PON, and core line division multiplex.

In Embodiment 1-1, the configuration used for TWDM-PON was exemplified, but it may be applied to a PON that shares resources other than wavelength and time. For example, it may be applied to OFDM-PON that divides and multiplexes an electrical frequency resource of one wavelength, SCM-PON that divides and multiplexes an electrical frequency resource of one wavelength, CDM-PON that divides and multiplexes with a code, and core line 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 is true if the function of wavelength-division multiplexing the wavelength resources of TWDM-PON is replaced with the function corresponding to the function required for division-multiplexing the respective resources to be multiplexed.

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

Although the TWDM-PON is taken as an example, if the frame for identification in the PON section is handled in the same way as in Embodiments 1-2 to 1-4, the same is true for other PONs. effect is obtained. For example, in the case of IEEE standard GE-PON, 10GE-PON, etc., instead of the GEM frame, an LLID is assigned, and the LLID-attached frame is conducted between the switch and other parts. good.

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

Although the TWDM-PON is taken as an example, if the control information is handled in the same way and processed via a switch, the same is true for other PONs as in Embodiments 1-2 to 1-4. effect is obtained.
