Abstract
Two path setting sides are determined between a pair of nodes in a network, and two path setting messages are created. The two path setting messages each includes information on a path switch default direction, a wait-to-restore timer value, and a mode identifier identifying a revertive mode. Then the two different communication paths are concurrently set between the pair of nodes by transmitting concurrently the created two path setting messages between the pair of nodes. In the case of the revertive mode, a communication path set on a side identified by the path switch default direction is operated as a working path either in an initial state or when no faults have occurred during a time period indicated by the wait-to-restore timer value after recovery of the fault on the first side.
