Abstract
A communication node selecting unit selects a communication node where a time for transferring a failure notification message from a plurality of failure detected communication nodes which detect a plurality of failures on an active communication path to be protected is within a predetermined time, and a backup communication path designing unit searches, based on the selected communication nodes, for a common backup communication path which bypasses the failures.
