ABSTRACT:
A relay node comprising a reception station for receiving a route trace control message including routing information on a path used for data transfer from a starting node to a terminal node from the preceding node on the path, an editing section for, if the home node is boundary node located at the boundary of a routing information shielding section on the path, editing so that a portion on the routing information shielding section of the routing information included in the route trace control message received by the reception section cannot be identified, and a transmission section for sending out a route trace control message after the edition to the node of the subsequent stage, which is located on the path.
