Abstract
A node positioned in a protection path for a working path stores identification information available to identify a source node and an end node. The identification information is contained in a signaling message transmitted to the end node through the protection path from the source node in order to set a usage reservation of the protection path. The node notifies the failure detection to an address identified by the stored identification information in response to a failure detection of the protection path.
