Abstract
A method and a device for each network element node in a transoceanic multiplex section shared protection ring to automatically discover a cross-node service topology. 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 configured 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. According to the embodiment of the present invention, by adopting a data 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.
