step S141, the network element name and the network element port number of each transmission network element on the transmission path are respectively matched with the protection device name and the port information of the protection device in the multiplexing segment protection information, so as to obtain the transmission network element protected by the transmission multiplexing segment corresponding to the multiplexing segment protection information.
Step S142, acquiring the transmission network element connected to the transmission path of the matched transmission network element, matching the network element name and the network element port number of the connected transmission network element with the protection device name and the port information of the protection device in the protection information of the multiplexing segment, and determining whether the connected transmission network element is the transmission network element protected by the transmission multiplexing segment corresponding to the protection information of the multiplexing segment.
Step S143, if the connected transmission network element is the transmission network element protected by the transmission multiplexing section corresponding to the multiplexing section protection information, the connected transmission network element is used as a newly matched transmission network element, and according to the network element name and the network element port number of the matched transmission network element, the network element name and the network element port number of the newly matched transmission network element, and each logical connection relationship and port information of the multiplexing section protection information, it is determined whether the matched transmission network element and the newly matched transmission network element have a connection relationship in the transmission multiplexing section corresponding to the multiplexing section protection information.

When the network element name is matched, if a certain transmission network element on the transmission path is not matched with the protection device name in the multiplex section protection information table, the transmission network element is not in the multiplex section protection, the name matching aiming at the current network element is finished, and the next network element name on the transmission path is extracted to be matched with the protection device name in the multiplex section protection information table.
When matching the port numbers, because the "port information" in the protection information table of the multiplexing section is a combination of two port numbers divided by punctuation marks, the two port numbers need to be respectively matched with the port numbers of the transmission network element, and if the matching is unsuccessful, it indicates that the transmission network element is not in the protection of the multiplexing section.

Step S143-2, if the logical connection relation of the multiplex section protection information exists, comparing the network element port number of the matched transmission network element, the network element port number of the newly matched transmission network element with the port information corresponding to the logical connection relation of the matched transmission network element and the newly matched transmission network element, and determining whether the corresponding port information includes the network element port number of the matched transmission network element and the newly matched transmission network element port number.
Step S143-3, if the network element port number of the matched transmission network element and the network element port number of the newly matched transmission network element are included, determining that the matched transmission network element and the newly matched transmission network element have a connection relationship in the transmission multiplexing section corresponding to the multiplexing section protection information.
In this embodiment, the transmission network element connected to the matched transmission network element is obtained, the transmission network element connected to the matched transmission network element is matched with other network elements in the transmission multiplexing section, and it is determined whether the transmission network element connected to the matched transmission network element and the transmission network element connected to the transmission network element have a connection relationship in the transmission multiplexing section.
If the matched transmission network element and the transmission network element connected to the transmission network element have a connection relationship in the transmission multiplexing section, the following step S144 may be executed.
As an optional embodiment, the step of superimposing the multiplexing segment ring logic topology of the transmission multiplexing segment and the transmission path based on the connection relationship between the matched transmission network element and the newly matched transmission network element in the transmission multiplexing segment in step S144 may specifically include:
step S144-1, the protection device name in the protection information of the multiplex section corresponding to the connection relation is obtained in the logical topology of the multiplex section ring.
Step S144-2, the obtained protection device name and the network element name of the transmission network element corresponding to the connection relation are merged with the same name, so that the extracted multiplex section ring logic topology is superposed with the transmission path.
In this embodiment, the information in the multiplexing segment ring logical topology is read by the topology map tool, and the names of the protection devices of the multiplexing segment protection information and the names of the transmission network elements on the transmission path are merged with each other based on the connection relationship, so as to generate a merged topology map.
