The cell packets generated by OTN service cutting contain two types of data packets: multicast cells and unicast cells. In order to facilitate the management of cross-connect configuration, the management plane will assign a unique cross-connect ID to each cross from the resource pool when configuring each service cross. In the existing propagation process of multicast services and unicast services, the destination of each unicast service or multicast service uniquely corresponds to the cross-connect ID in the same network element.

[0003] The existing cross-configuration verification is based on sequential storage and recording of cross-configuration issued in the network element. When adding or deleting cross-configuration, it is necessary to traverse the cross-configuration in the database through a circular table lookup to complete the cross-configuration verification and update the cross-configuration database. It takes a long time to complete the entire cross-configuration verification and update, which affects the service provisioning time and configuration efficiency. When a large number of services are issued to the network element, the time for processing cross-configuration data will increase dramatically. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0025] It should be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0026] It should be understood that, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first OTN device and the second OTN device are only used to distinguish different OTN devices, and their order is not limited. Those skilled in the art can understand that the words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not necessarily limit them to be different.

[0027] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0028] To facilitate understanding of the embodiments of the present application, some words involved in the embodiments of the present application are briefly explained below.

[0029] 1. Optical Demultiplexing Unit (OTN): OTN is a transmission network based on wavelength division multiplexing technology and organized at the optical layer. It is the next-generation backbone transmission network. OTN is a new generation of "digital transmission system" and "optical transmission system" regulated by a series of recommendations of the International Telecommunication Union Telecommunication Standardization Division (ITU-T for ITU Telecommunication Standardization Secto, ITU-T) such as G.872, G.709, and G.798. It will solve the problems of traditional wavelength division multiplexing (WDM) networks, such as poor wavelength / sub-wavelength service scheduling capabilities, weak networking capabilities, and weak protection capabilities.

[0030] 2. Electrical Cross Connection (OTN Electrical Cross Connection): OTN electrical cross connection technology uses optical demultiplexing unit (ODU) k as the granularity for mapping, multiplexing and cross-connection. It uses cell and packet switching technology to cut OTN services according to fixed or random packet lengths, adds packet type, timestamp and destination information to the cut cell header, and uses packet switching chips for scheduling to complete the exchange, aggregation and transmission of various granular service data packets.

[0031] 3. Cell and Packet Switching: Cell and Packet Switching technology includes two types of data packets, multicast cells and unicast cells, in the cell packets generated by OTN service cutting. The multicast cell adds the multicast ID allocated by the management plane from the multicast cross resource pool to the cell header. The destination completes the replication and assembly of the multicast service packet according to the allocated multicast ID. For unicast cells, the data packet is forwarded and transmitted through the link number in the packet header. At the same time, in order to facilitate the management of cross configuration, the management plane will allocate a unique cross ID to each cross from the resource pool when configuring each service cross.

[0032] 4.Unicast Services: OTN multicast services have one or more senders and one or more receivers participating in data transmission traffic.

[0033] 5. Multicast Services: OTN unicast services have one sender and one receiver participating in data transmission traffic.

[0034] 6. Communication board: Communication equipment generally includes a chassis, in which multiple communication boards are installed to realize communication functions. The communication boards are inserted into the installation slots of the chassis in parallel. The communication board includes multiple slots, each of which includes at least one port. The communication board can act as a source to send cell information to the communication board of another communication device, and can also act as a sink to receive cell information sent by the communication device.

[0035] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] The existing multicast services and unicast services have the following characteristics: 1. Each multicast ID of a multicast service uniquely corresponds to the source end in the same network element. 2. Each destination end of a unicast service or multicast service uniquely corresponds to the cross ID in the same network element.

[0037] The existing cross-configuration verification is based on sequential storage and recording of cross-configuration issued in the network element. When adding or deleting cross-configuration, it is necessary to traverse the cross-configuration in the database through a circular table lookup to complete the cross-configuration verification and update the cross-configuration database. It takes a long time to complete the entire cross-configuration verification and update, which affects the service provisioning time and configuration efficiency. When a large number of services are issued to the network element, the time for processing cross-configuration data will increase dramatically, which will increase the service provisioning time dramatically.

[0038] See also Figure 1 , Figure 1 A schematic flowchart of the steps of a configuration method provided by an embodiment of the present application is shown. The provided configuration balancing method is applied to a first communication board of a first OTN device. The first communication board includes multiple slots, each of which includes at least one port. The first communication board is used to receive cell information sent by a second communication board of a second OTN device to complete the configuration of the port of the first communication board.

[0039] like Figure 1 As shown, the provided configuration method includes steps S101 to S103.

[0040] S101. Receive the cell information sent by the second communication board, where the cell information includes a slot port identifier and configuration information of a first target port to be configured.

[0041] Specifically, when the second communication board, as the source, sends a cell information to the first board, as the destination, it can be a unicast configuration request initiated by the second communication board to a first target port of the first board, or it can be a multicast configuration request initiated by the second communication board to multiple first target ports of the first board. By including the slot port identifier and configuration information of the first target port in the cell information, the slot port identifier is used to help the second communication board confirm the slot and port of the first target port, for example, the first port of slot 2 is the first target port. After cross-checking with the first target board, the configuration information in the cell information can be used as the configuration information of the first target port.

[0042] It should be noted that when the configuration mode of the second communication board and the first communication board is unicast configuration, cross-checking only needs to be performed at the host end. When the configuration mode of the second communication board and the first communication board is multicast configuration, multicast configuration of the disconnection of the sending of the frame signal is also required at the source end.

[0043] Exemplarily, the slot port identifier is composed of a slot identifier and a port identifier, such as the slot identifier is 1 and the port identifier is 5, and then the 5th port of slot 1 in the first communication board can be found as the first target port. In some embodiments, the slot port identifier is composed of "slot identifier + port identifier", such as the slot port identifier is 1-5, and then the 5th port of slot 1 in the first communication board can be found as the first target port. The slot port identifier is used to confirm the slot and port of the target port, and the embodiment of the present application does not limit the form of the slot port identifier.

[0044] It should be noted that, in some embodiments, the slot port identification includes slot identification information and port identification information. Figure 2 , Figure 2 It is a schematic flowchart of the steps of a configuration information query method provided in an embodiment of the present application.

[0045] like Figure 2 As shown, the provided configuration information query method includes steps S101a to S101b.

[0046] S101a. Match the slot identification information and port identification information corresponding to the first target port with the slot identification information and port identification information of the port in the preset cross-connection information table respectively.

[0047] S101b. Query the preset cross table to see whether the successfully matched slot identification information and port identification information have corresponding configuration information.

[0048] According to the slot identification information and port identification information corresponding to the first target port, for example, the slot identification information corresponding to the first target port is 3 and the port identification information is 5, the cross information table is queried to see whether there is data of slot 3 and port 5. If the query is successful, the current configuration information of the port in the cross information table is obtained. The provided method only needs to use the slot and port as indexes to search for the configuration information of the first target port once to complete the cross configuration check. The current configuration of the first target port can be quickly confirmed, which improves the speed of the configuration method provided in the embodiment of the present application.

[0049] In some embodiments, receiving the cell information sent by the second communication board, the cell information including the slot port identifier and configuration information of the first target port to be configured, includes: parsing the received cell information to obtain the slot port identifier and configuration information of the first target port to be configured. The first communication board as the sink parses the cell information sent by the source end to obtain the first target port configured this time, and then completes the configuration of the first target port after the cross-check is completed.

[0050] S102. According to the slot port identifier corresponding to the first target port, query in a preset cross information table whether there is corresponding configuration information for the first target port, the cross information table including the slot port identifier and configuration information of the port of the first communication board.

[0051] Specifically, the first communication board parses the frame information sent by the second communication board to obtain the slot port identifier of the first target port configured this time, and queries whether there is corresponding configuration information for the first target port in the preset cross-information table according to the slot port identifier to confirm whether the configuration information corresponding to the first target port in the frame information should be written into the cross-information table.

[0052] It should be noted that the cross-information table provided in the embodiment of the present application can be newly created when the communication board is installed, which includes the slot and port identifiers in the communication board and the configuration information of the port. By creating the cross-information table, the current configuration status of the first target port can be quickly confirmed before the first communication board needs to configure the first target port as the host end, thereby improving the speed of the configuration method provided in the embodiment of the present application.

[0053] In some embodiments, before receiving the cell information sent by the second communication board, the method further includes: initializing the configuration information of the preset cross information table to invalid data. The configuration information of each port is initialized to invalid data before using the configuration information of the cross information table, so that each port remains identifiable in the cross information table when it is not configured.

[0054] S103. If the configuration information of the first target port cannot be found in the cross-information table, the configuration information of the first target port is written into the cross-information table to complete the configuration of the first target port.

[0055] Specifically, if the configuration information of the first target port cannot be found in the cross-information table according to the slot port identifier, then the configuration information of the first target port in the cell information is directly written into the cross-information table, and when the first target port is subsequently configured, the written configuration information is compared to determine whether to update the configuration of the first target port. By using the provided method to create a cross-information table, when the cell information sent by the second communication board is received, the slot port identifier of the first target port in the cell information is matched with the slot port identifier corresponding to the port in the cross-information table. When the match fails, the configuration information of the first target port is written into the cross-information table to complete the configuration of the first target port. This greatly improves the efficiency of cross-configuration data processing.

[0056] For example, Figure 3 As shown, Figure 3is a schematic block diagram of a configuration method provided in an embodiment of the present application. When a user sends a cross-connection configuration through an upper layer source end, such as a second communication board of a second OTN device, Figure 3 As shown, if the verification of the current cross configuration and the historical configuration is to be completed, it is necessary to traverse the entire current cross verification data table one by one. As the configuration business volume increases, the time for verifying and searching the configuration increases exponentially. By using the configuration proposed in the embodiment of the present application, a verification data table including multicast identification information and cross identification information, such as multicast ID and cross ID, is designed based on the slot port. Each time the cross configuration is issued, it is only necessary to search the cross ID of the first target port with the slot and port as the index to complete the cross configuration verification. If there are 100 crosses in the current configuration, the processing time required using the verification scheme of the present invention is 1 / 100 times that of the current verification method. At the same time, the error information of the verification abnormality is reported to the user, and the abnormal configuration is quickly identified. In a large business volume scenario, the efficiency of fault location can be improved.

[0057] In some embodiments, the configuration information in the cross information table includes preset cross identification information and preset cross configuration information, and the configuration information corresponding to the first target port includes cross identification information and cross configuration information. Figure 4 , Figure 4 is a schematic flow chart of the steps of another configuration method provided in an embodiment of the present application. Figure 1 The configuration method provided is different in that Figure 4 The provided method further includes steps S104 to S106.

[0058] S104. If the configuration information corresponding to the first target port is found in the cross-information table, it is determined whether the preset cross-identification information is consistent with the cross-identification information.

[0059] S105. If the preset cross-connection identification information is consistent with the cross-connection identification information, write the cross-connection configuration information of the first target port into the cross-connection information table to replace the preset cross-connection configuration information.

[0060] S106. If the preset cross-identification information is inconsistent with the cross-identification information, generate cross-configuration failure information.

[0061] Since the host end of each unicast service or multicast service uniquely corresponds to the cross-identification information, such as the cross-ID, in the same network element. The cross-identification information corresponding to the configuration information in the cell information is compared with the preset identification information of the current port in the cross-identification table, such as the cross-ID currently configured for the port. If the preset cross-identification information is consistent with the cross-identification information, the cross-configuration information can be updated with the preset cross-configuration information of the first target port in the current cross-information table to complete the configuration of the first target port. When the configuration fails, cross-configuration failure information is generated and reported to facilitate rapid location of the abnormally configured port. In scenarios with large business volume, the efficiency of cross-anomaly verification interception and positioning is improved.

[0062] In some embodiments, the second communication board includes a plurality of slots, each slot includes at least one port, and the cell information includes a slot port identifier and configuration information corresponding to the second target port to be configured. Before receiving the cell information sent by the second communication board, the method further includes: obtaining a multicast information table, the multicast information table including the slot port identifier and preset configuration information corresponding to the port of the second communication board.

[0063] Since each multicast identification information of a multicast service, such as a multicast ID, uniquely corresponds to the source end in the same network element. When the second communication board is used to configure multiple ports in the first communication board, before receiving the cell information sent by the second communication board, the first communication board can confirm the configuration of each port in the second communication board as the source end by obtaining a multicast information table including the slot port identification and preset configuration information corresponding to the port of the second communication board. Then, when receiving the multicast configuration information corresponding to the second target port, verification can be completed based on the multicast identification information table.

[0064] Exemplarily, before receiving the cell information sent by the second communication board, the method further includes: initializing the configuration information of the multicast information table to invalid data. By initializing the configuration information of each port to invalid data before using the configuration information of the multicast information table, each port remains identifiable in the multicast information table when it is not configured.

[0065] For example, please refer to Figure 5 , Figure 5 is a schematic flow chart of the steps of another configuration method provided in an embodiment of the present application. Figure 1 The configuration method provided is different in that Figure 5 The provided method further includes steps S107 to S108.

[0066] S107. According to the slot port identifier corresponding to the second target port, query in the multicast information table whether there is corresponding configuration information for the second target port.

[0067] S108. If the multicast information table does not contain the configuration information of the second target port, write the configuration information of the second target port into the multicast information table to complete the configuration of the second target port.

[0068] When the second communication board initiates the multicast configuration as the source, the first communication board parses the cell information sent by the second communication board, obtains the slot port identifier corresponding to the second target port as the source, and then searches the multicast information table for the corresponding configuration information according to the slot port identifier. When there is no corresponding configuration information for the second target port in the multicast information table, the configuration information in the cell information is written into the multicast information table, so that the multicast information table can be updated and the multicast configuration can be completed. This greatly improves the efficiency of multicast configuration data processing.

[0069] Exemplarily, the configuration information in the multicast information table includes preset multicast identification information and preset multicast configuration information, and the configuration information corresponding to the second target port includes multicast identification information and multicast configuration information. Figure 6 , Figure 6 is a schematic flow chart of the steps of another configuration method provided in an embodiment of the present application. Figure 5 The configuration method provided is different in that Figure 6 The provided method also includes steps S109 to S111.

[0070] S109. If the configuration information corresponding to the second target port is found in the multicast information table, it is determined whether the preset multicast identification information is consistent with the multicast identification information.

[0071] S110. If the preset multicast identification information is consistent with the multicast identification information, the multicast configuration information of the second target port is written into the multicast information table to replace the preset multicast configuration information;

[0072] S111. If the preset multicast identification information and the preset multicast configuration information are inconsistent, generate multicast configuration failure information.

[0073] Since the source of each multicast service uniquely corresponds to the multicast identification information, such as the multicast ID, in the same network element. A comparison is made between the multicast identification information corresponding to the configuration information in the cell information and the preset identification information of the current port in the multicast information table, such as the multicast ID currently configured for the port. If the preset multicast identification information is consistent with the multicast identification information, the multicast configuration information can be updated with the preset multicast configuration information of the second target port in the current multicast information table to complete the configuration of the second target port. When the configuration fails, multicast configuration failure information is generated and reported to facilitate rapid location of the abnormally configured port. In scenarios with large business volume, the efficiency of cross-anomaly verification interception and positioning is improved.

[0074] The present application provides a configuration method, which adopts the provided method to create a cross information table, and when receiving the cell information sent by the second communication board, matches the slot port identifier of the first target port in the cell information with the slot port identifier corresponding to the port in the cross information table, and writes the configuration information of the first target port into the cross information table when the match fails, thereby completing the configuration of the first target port. The efficiency of cross configuration data processing is thereby greatly improved.
