At the same time, in the description of the present invention, the serial numbers of each step are only used to distinguish between steps, and do not mean that each step needs to be strictly executed in the order of the serial numbers.

[0057] Glossary:

[0058] lsp: Label Switched Path. A path along which a forwarding equivalence class passes in an MPLS network is called a label switched path (LSP).

[0059] Gress: Source / sink node.

[0060] Transit: intermediate node.

[0061] reverseNode; static node.

[0062] lspNode:lsp node.

[0063] lspingress / egress: lsp ingress / lsp egress.

[0064] lsptransit: lsp intermediate node.

[0065] The present invention provides a method for synchronously assembling lsp service data of an IPRAN device, such as Figure 1 As shown, the steps include:

[0066] S1. Obtain basic information of online devices. Specifically, the basic information includes: device online status, device MAC, device ID, device IP and device type.

[0067] S2. Collecting the LSP service data of online devices based on basic information includes the following steps:

[0068] S21. When the device status is displayed as online and the device MAC exists, verify whether the device exists according to the device ID.

[0069] Verifying whether a device ID exists can be achieved in the following way: first match the device ID in the device basic information cache pool; if the match fails, then match the device from the database; if the device matches successfully, write the device basic information into the device basic information cache pool; if the match still fails, the verification fails and the device does not exist.

[0070] S22. If the device exists, the device port information and device lsp service data are obtained through the device IP and device type; the device port information is obtained through the device IP and device type in the following manner: according to the device IP and device type, a match is performed in the device command group to obtain the device port information command group; according to the matched port information command group, the device port information is obtained, and parsed to obtain the device port information.

[0071] The following method can be used to obtain device LSP service data through device IP and device type: match the device MIB library according to the device IP and device type to obtain the MIB of the device LSP service data; obtain the device LSP service data according to the MIB of the matched device LSP service data, parse it, and obtain the device LSP service data.

[0072] S3, assembling the collected LSP service data of a single device, including the following steps:

[0073] S31. Update Gress node information: first obtain the lspingress / egress information of a single device and compare it with the existing lsp data. If there is new data, add the newly added data to the existing lsp data. If there is a change, update the existing lsp data. If the old data does not exist, delete the old data; re-perform additional data completion operations on the lsp information that has been added and modified by the new data.

[0074] S32. Update Transit node information: Get the lsptransit information of a single device: compare with the existing lsp data, if there is new data, add it, if there is change, update it; if the old data does not exist, delete the old data; re-perform additional data completion operation on the lsp information that has been added and modified by the new data.

[0075] S33, update the reverseNode node information and assemble at the same time: clean, adjust and process the data before assembly according to the ingress / egress data type; clean, adjust and process the data before assembly according to the transit data type; in the overall lsp data pool, including ingress / egress / transit, for the changed lsp information, recursively assemble a complete lsp link and mark it according to the ingress and outgress lsp labels, next hop and other information.

[0076] S34, update to lspNode node information: according to the newly assembled complete lsp link, compare them one by one with the currently used lsp link:

[0077] If the newly assembled link is new, it is directly added to the current lsp link list;

[0078] If the newly assembled link is an update, the current LSP link is updated, including the LSP information of a single LSP device and the addition and deletion of transit devices;

[0079] If the newly assembled LSP link is the same as the current LSP link but in the opposite direction, the new LSP link is reversed before the update operation is performed;

[0080] If it is found that the current LSP link no longer exists or has failed, the status of the LSP link is synchronously updated.

[0081] S4. Generate lsp link data.

[0082] In the specific implementation process, the LSP link related devices are added to the network management system, including the devices corresponding to the ingress / transit / egress nodes. If any device node in the LSP link is missing in the network management, the LSP link data cannot be assembled.

[0083] like Figure 2 As shown, in the network management system, open the LSP service configuration page and manually click "Assemble LSP", the LSP link assembly method will be triggered, and finally the newly assembled LSP link data will be generated and displayed.

[0084] It can be seen that the present invention presets device LSP service MIBs for multiple device types, and obtains the device LSP service MIB of the device type by matching the device type of the online device to collect and assemble device LSP service data and generate LSP link data.

[0085] The present invention collects statistics on the devices currently running in the existing network, identifies the device models and versions, and performs a large amount of analysis on the LSP link assembly related work, thereby unifying the LSP link assembly model that is ultimately suitable for all devices;

[0086] In response to the requirement for fast LSP link assembly, the present invention supports two methods: unified assembly of the entire network and incremental assembly by device. When it is used for the first time or the existing network equipment has changed significantly, the entire network assembly can be used. When the environment is already stable, incremental assembly of devices is generally used, which can achieve fast and comprehensive results.

[0087] In order to ensure that the LSP link does not affect the business, the present invention performs and analyzes the operations and impacts involved in the entire assembly method. In the entire method, no write operations are allowed on the device, and there are only a small number of read operations. A cache mechanism is used to avoid a large number of repeated device reads to avoid a major impact on the device business.

[0088] In order to ensure the reliability and stability of the LSP link, assembly and post-assembly are distinguished according to the impact. Before the assembly is completed, no operation will be performed on any LSP link data in the existing network; only after the assembly is completed will it be accurately compared and partially modified with the current LSP link, without any batch data modification.

[0089] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
