Claim:
1. A networking device, comprising: a transceiver configured to receive a Protection State Coordination (PSC) message from another networking device; a state detecting unit configured to detect a local PSC state of the networking device; an inconsistency identifying unit configured to determine whether the received PSC message is a No Request (NR) message and the detected local PSC state is a Do-not-Revert (DNR) state; an inconsistency removing unit configured to change the local PSC state from the DNR state to a normal state, if the inconsistency identifying unit determines that the received PSC message is an NR message and the detected local PSC state is a DNR state; and a traffic path selecting unit configured to transport traffic using a working path instead of a protection path to the other networking device, if the local PSC state of the networking device is changed to the normal state.
