ABSTRACT:
A method of setting up a backup path for a primary path on a network includes the steps of grouping nodes constituting the primary path into segments each including a plurality of nodes, and setting a backup path connecting between a head node and end node of each of the segments separately for each segment by notifying of information about segment position by a primary-path-provision requesting message.
