Provided are an automatic protection switching (APS) state processing method, device and APS node, the method comprising: determining that the status of an APS node is at least one of the following: the APS node issues a reverse request (RR) code, and receives a reverse request code of a non-signal failure (SF) and a non-signal degradation (SD) and RR codes issued by other nodes except the APS node; the APS node issues an RR code, enters wait to restore (WTR) time after receiving the reverse request code of a signal failure (SF) and a signal degradation (SD) and the RR codes issued by other nodes except the APS node, and exceeds the WTR time; and revoking the switching state of the APS node. The present invention solves the problem in the relevant art of service packet loss caused by frequent switching of the APS state of a node between different switching states, shortens the processing time of protection switching, and improves service stability. |
