<p>PROBLEM TO BE SOLVED: To prevent the increase of the communication traffic of a control path by means of a search frame. SOLUTION: A node 11 being a search source generates the search frame addressed to a node 12 being a search destination. It is transmitted to omnibearing control paths 23 and 26 except for the control path with a fault by multiple addresses. Relay nodes 14, 16 and 13 receiving the search frames addressed to the other nodes transfer the search frames only to the control paths 24, 27 and 22 for the node 12 being the address of the search frames which are set in the routing table of the respective nodes. The routing tables of the respective nodes are updated by a response frame returned from the node 12 being the search destination by following the same route as the search frame in an opposite direction.</p> |
