ABSTRACT:
In an ATM virtual path switching node, upon being notified of a current virtual path by a virtual path monitoring unit, a link fault determination unit compares the number of faulty current virtual paths with a predetermined threshold value. When the number of faulty current virtual paths is equal to or larger than the threshold value, a link fault is determined, and a message communication unit transmits/receives a link fault notification signal to/from another ATM virtual path switching node. When the number of faulty current virtual paths is smaller than the threshold value, a current virtual path fault is determined, and the message communication unit transmits/receives a virtual path fault notification signal to/from another ATM virtual path switching node. The message communication unit transmits a switching control signal for designating switching from the current virtual path to a stand-by virtual path. A current virtual path information management unit manages correspondence between the current virtual path having, as one switching terminal, a self ATM virtual path switching node and a plurality of links in an ATM network.
