<p>Disclosed are a pseudo wire (PW) protection method, device and node, the method comprising: monitoring a head node receiving PW packets on a master PW path, the master PW path being a current working PW path; and directly determining whether it is necessary to perform a master/slave PW switchover operation according to the monitoring result. The present invention can detect the PW status without being based on OAM and BFD, thus reducing the detection time required for the switchover protection mechanism, and does not require additional use of system resources, thus improving resource utilization.</p> |
