Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a service path restoration method apparatus, electronic device, and storage medium. Background Technology

[0002] The transmission operation and maintenance workbench manages the resources and service data of the transmission profession. The resource data mainly relies on the Operation and Maintenance Center (OMC) of each manufacturer to report according to the specifications. After the transmission workbench collects and parses the data, it stores and manages it. The service data is mainly generated through the circuit scheduling process, including Synchronous Digital Hierarchy (SDH) circuits, Packet Transport Network (PTN) circuits, Optical Transport Network (OTN) circuits, Slicing Packet Network (SPN) circuits, etc.

[0003] Traditional OTN service paths rely on verifying the relationship between OTN circuits and optical channels, and then routing the optical channels in series. Specifically, the routing data for the optical channels is not reported by the equipment manufacturer's OMC, requiring periodic concatenation by the upper layer using a concatenation algorithm. However, current concatenation algorithms are complex, relying on numerous basic data (network elements, boards, ports, time slots, signal flow direction, topology connections). The accuracy of any data can affect the routing of the concatenated optical channels, and may even lead to concatenation failure, making it impossible to obtain an end-to-end path.

[0039] The following is combined Figures 1-6 This invention describes the service path restoration method and apparatus provided in embodiments of the present invention.

[0040] Figure 1 This is a flowchart illustrating the business path restoration method provided by the present invention, as follows: Figure 1 As shown, including but not limited to the following steps:

[0041] S110, Obtain the subnet connection data of the subnet connection to be restored;

[0042] S120, based on the resource management global identifier rmUID of the subnet connection to be restored, obtain the routing data of the subnet connection to be restored;

[0043] S130, if there is no data of route type SNL in the routing data, then the service path of the subnet connection to be restored is formed based on the OTN service layer model.

[0044] It should be noted that the execution subject of the task construction method provided in this application embodiment can be a server or computer device, such as a tablet computer, laptop computer, ultra-mobile personal computer (UMPC), or netbook.

[0045] Figure 2 This is a schematic diagram of the OTN service path model provided by the present invention, as shown below. Figure 2 As shown, according to the OTN path model recommended by ITU-T G.872, OTN services can be divided into: Client trail: Optical Channel Client Layer Path; ODUk trail: Optical Channel Data Unit Path; OTUk trail: Optical Channel Transport Unit Path; OCh trail: Optical Channel Layer Path; OMStrail: Optical Multiplex Section Path; OTS trail: Optical Transport Section Path (multi-layer path).

[0046] Here, the routing data includes subnet connection (SNL), topology connection (TPL), and signal flow direction (SIF).

[0047] Figure 3 This is a schematic diagram of the path-related data association of the subnet connection provided by the present invention, such as... Figure 3 As shown, the subnet connection data of a certain layer is obtained. The route of the current subnet connection is obtained from the subnet connection and routing data, which may include SNL (Sub NetLink), TPL (Topo Link), and SIF (Signal Flow). The route of the next layer SNL is expanded by iterating layer by layer. The process is recursively repeated until all SNL routes are iterated to only contain TPL. This indicates that the current path has been restored to the lowest layer route, i.e., the end-to-end path.

[0048] The service path for forming the subnet connection to be restored based on the OTN service hierarchy model specifically includes:

[0049] Based on the OTN service hierarchy model, TPL and SIF are concatenated sequentially from top to bottom according to the routing sequence number to obtain the service path of the subnet connection to be restored.

[0050] The service path restoration method provided in this application embodiment obtains subnet connection data of the subnet connection to be restored; obtains routing data of the subnet connection to be restored based on the resource management global identifier (rmUID) of the subnet connection to be restored; if there is no data of route type SNL in the routing data, then a service path of the subnet connection to be restored is formed based on the OTN service hierarchy model. According to the OTN service hierarchy model, the service path of the subnet connection is restored layer by layer, realizing the end-to-end path restoration of the subnet connection without relying on complex basic data, thus improving the fault tolerance of service path restoration.

[0051] In an optional embodiment, after obtaining the routing data of the subnet connection to be restored based on the resource management global identifier (rmUID) of the subnet connection to be restored, the method further includes:

[0052] If the routing data contains data of type SNL, then the subnet connection corresponding to the SNL type data is taken as a new subnet connection to be restored, and the routing data of the new subnet connection to be restored is obtained, until the routing data no longer contains data of type SNL.

[0053] In optional embodiments, the OTN service layer model includes the EoS service layer model, the EoO service layer model, the SDH service layer model, and the OTN transparent transmission service layer model, as shown in Table 1 below.

[0056]

[0057] Figure 4 This is a schematic diagram of the business path restoration steps provided by the present invention. For ease of understanding, the following is combined with... Figure 4 The preferred method for restoring the business path of the present invention will be described.

[0058] 101. Obtain the subnet connection data (SNL) that needs to be restored.

[0059] 102. Match the subnet connection rmUID obtained through process node 101 with the rmUID of the subnet connection and route (SNT) to obtain the current layer route of the current subnet connection.

[0060] 103. Analyze the subnet connection and routing (SNT) data matched by process node 102 (the routing type will have three types of data: TPL, SIF, and SNL) and analyze whether there is routing data with the routing type "SNL".

[0061] 104. After analyzing the routing data of process node 103, if there is no routing data of type "SNL", it means that the current level of routing has been reached and there is no need to iterate layer by layer. Proceed to process node 106. If there is a route of type "SNL", obtain the rmUID of the current SNL and match the subnet connection and routing (SNT) data again.

[0062] 105. Analyze the subnet connection and routing (SNT) data matched by process node 104 again to see if there is any routing data with the routing type "SNL". If so, proceed to process node 106. Otherwise, continue recursively layer by layer until the matched subnet connection and routing (SNT) data only contains data with the routing type "TPL". This indicates that the current routing has been analyzed to the lowest level and can no longer be analyzed.

[0063] 106. In the analyzed SNT, according to the OTN service hierarchy model, TPL and SIF are concatenated sequentially from top to bottom according to the routing sequence number to form an end-to-end service path, and the process ends.

[0064] In summary, the service path restoration method provided in this application restores the OTN service path layer by layer by collecting subnet connection and routing data, obtaining end-to-end path information for each subnet connection. For sudden device or port alarms, by matching and associating alarm resource objects with restored path nodes, the scope of services affected by the alarm can be quickly analyzed. This allows for timely adjustments and repairs to affected or potentially interrupted services, reducing the risk of service interruption and improving the efficiency of service fault handling. Furthermore, the restored service path allows for co-routing analysis of upper-layer services, identifying various potential problems in the routing, including shared network elements, boards, ports, optical cables, and bearers in primary and backup paths. This facilitates maintenance personnel in promptly identifying current network vulnerabilities, enabling planned and targeted adjustments to the transmission network, strengthening network protection measures, and improving the security and reliability of the transmission network.

[0071] The recursive update module is used to, if the routing data contains data of type SNL, then use the subnet connection corresponding to the SNL type data as the new subnet connection to be restored.
