ABSTRACT:
A packet transmission method is provided when there occurs a double fault in working paths of a 1:N configuration and when packets thereon are to be bypassed from the working paths to a recovery path, the packet can be transferred to the recovery path while retaining packet priority classes or VPNs on the recovery path. If faults occur in both a first line on which is set a first label-switched path and a second line on which is set a second label-switched path, packets which should flow respectively through the first and second label-switched paths are bypassed to the recovery path. At this time, different labels are affixed to the packets such that the thus-labeled packets are transferred to the recovery path.
