Abstract

A transport control server (TCS) identifies a backup path B switched over to from an active path A due to a path change or a fault, based on information in a path change notification or a fault notification. The TCS identifies a backup path C affected by the switchover from the active path to the backup path. The TCS identifies nodes in which a setting change to delete the backup path C is needed and nodes in which a backup path D should be set up as an alternative to the backup path C and transmits a setting change notification to these nodes.
