According to the present invention, the method for automatically discovering a cross-node service topology comprises the following steps: at the node, generating a message containing service identification information of the node, the service identification information being used for identifying a service flow config- ured for a protection group; sending the message containing the service identification information through the transoceanic multiplex section shared protection ring; and at at least one of other nodes, determining a cross-node service crossing topology according to the message containing the service identification information.

Published: — with international search report (Art. 21(3)) communication channel to periodically send a broadcast message and interacting with a configuration module and a protection protocol module in real time, when a fault occurs in a ring, it is guaranteed that correct service-level ring protection switching can be performed. A cross-node service topology automatic discovery mechanism simplifies the operation, decreases inconsistent error configurations, and is very convenient to use and maintain.
