摘要： 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.

摘要： The disclosure provides a method for bandwidth assignment of an Optical Burst Ring (OBRing), which includes that: a master node acquires current bandwidth resources, and excludes bandwidth resources occupied by over-the-master-node connections from the current bandwidth resources to obtain bandwidth resources to be assigned; and the master node assigns the bandwidth resources to be assigned to each node according to bandwidth requests of each node in the OBRing. The disclosure also provides a device for bandwidth assignment of an OBRing. According to embodiments of the disclosure, the bandwidth resources occupied by the over-the-master-node connections are excluded before bandwidth assignment is started, so that the problem of receiving conflict caused by an over-the-master-node service data connection is solved.
