Abstract: A state transition method and apparatus based on ROHC, and a computer storage medium are disclosed. The method comprises: when a state machine of a compressor is in an IR state, transiting a state of the state machine to an FO state when a decompressor can only successfully parse a static field of a service stream packet header; and transiting a state of the state machine to an SO state when the decompressor can successfully parse the static field and a dynamic field; when the state machine is in the FO state, transiting a state of the state machine of the compressor to the SO state when the decompressor can successfully parse the dynamic field; and when the state machine is in the SO state, transiting a state of the state machine to the FO state when the decompressor fails to parse the dynamic field within a preset time threshold.

Abstract: 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.
