ABSTRACT:
In a failure restoration system comprising a distributed hierarchical routing section which is adapted to set up a main path and previously determine an alternate path for the main path in a network, an alternate path selection section is adapted to obtain complete source route information for the main path when it attempts to set up the main path. The alternate path selection section adds the complete source information to a SETUP signaling message for setting up the alternate path, thereby provides a physical alternate path as much different as possible from the main path.
