The method of optical burst switching ring network automatic protection switching, and system node

Kinds of optical burst switching ring network automatic protection switching method, system and nodes, including the master node and each of the respective channel from the node optical power monitoring, and the monitoring results are compiled to a master node; master node is determined according to monitoring results when a failure occurs, switching to an operation instruction from the transmission node; perform switching operation from entering the node and the protection state. By the present invention, an optical burst switching ring network protection switching mechanism is introduced to realize the processing of failure, to ensure the optical burst switching ring network communication quality. Progress, the process of the present invention, by data and control channels of different switching operation, which addresses the protection requirements of optical burst switching ring network control channel of a centralized control loop, to ensure the channel is still able to follow the master type ring network operating mode operation, but also taken into consideration the utilization of the data channel transceiver, to maximize the availability of the node for each transceiver device.
