Provided are a method, a system and a node for implementing APS in an OBRing network. The method comprises: a master node and a slave node separately perform optical power monitoring on respective channels, and aggregate monitoring results to the master node; when determining, according to the monitoring results, that a fault occurs, the master node sends a switching operation instruction to the slave node; and the slave node performs a switching operation and enters a protection working state. With the disclosure, a protection switching mechanism is introduced to the OBRing, which implements the processing on fault and ensures the communication quality of the OBRing. Further, the method provided in the disclosure, by employing different switching operations on a data channel and a control channel, not only meets the protection requirement demanded by the centralized-control OBRing on a control channel ring, ensures that the control channel can still work in a master-slave ring working mode, but also considers the utilization of a transceiver on a data channel, and brings the availability of the transceiver on each node into full play. |
