Embodiment 1
[0060] An embodiment of the present invention provides a network element, see figure 1 , the network element includes:
[0061] Section layer (Section) OAM (Operation Administration Maintenance, operation, management, maintenance) processing unit 101, determination unit 102 and one or more ring network state machine processing units 103:
[0062] Each ring network state machine processing unit 103 corresponds to a ring network where the network element is located;
[0063] The segment layer OAM processing unit 101 is used to detect whether the adjacent link fails, and after the adjacent link fails, the link failure information is sent to the determination unit 102, and the protocol message is sent to the failed ring network Neighboring network elements, so that the network elements on the faulty ring network can receive the protocol message and determine the faulty ring network;
[0064] The determination unit 102 is configured to determine the failed ring network after receiv...
Embodiment 2
[0072] An embodiment of the present invention provides a network element, see figure 2 , the network element includes:
[0073] The segment layer OAM processing unit 201 is used to receive the protocol message, and forward the protocol message to the adjacent network element on the ring network where the failure occurs, so that the network element on the ring network where the failure occurs receives the protocol message and determines that the failure occurs ring network;
[0074] The protocol distribution unit 202 is configured to resolve the ring network identifier from the protocol message received by the segment layer OAM processing unit 201, and determine the ring network in which the failure occurs according to the ring network identifier;
[0075] Wherein, the protocol message is used to instruct the network element on the ring network where the failure occurs to perform protection switching;
[0076] The ring network identifier is an identifier of each ring network...
Embodiment 3
[0080] An embodiment of the present invention provides a network element, see image 3 , the network element includes:
[0081] memory 301 for storing information including program routines;
[0082] The processor 302, coupled with the memory 301 and the transmitter 303, is used to control the execution of the program routine, specifically including: after detecting that an adjacent link fails, determine one or more failed ring networks, and correct the failed ring network. The ring network performs protection switching, and the ring network identifier of the failed ring network is encapsulated in the protocol message;
[0083] The transmitter 303 is configured to send the protocol message encapsulated by the processor 302 to the adjacent network element on the failed ring network, so that the network element on the failed ring network can receive the protocol message and determine the failed ring network element .
[0084] Wherein, the ring network identifier is an identif...
