<p><P>PROBLEM TO BE SOLVED: To provide an inter-node communication movement system that eliminates the need to increase the number of keys to be shared to securely perform communication movement even when movement nodes as objects of communication movement increases and can freely control the communication movement. <P>SOLUTION: The inter-node communication movement system has nodes 110 and 120 as communication objects, communication mediation nodes 130 and 140, and a transfer management node 150. The node 110 has a function of communicating with the other node 120 through the communication mediation nodes 130 and 140 that the node 110 belongs to. The communication mediation nodes 130 and 140 have functions of performing communication transfer between the nodes 110 and 120 whose communication transfer is registered. The transfer management node 150 has a function of commanding the communication mediation node 130 to update a transfer destination in response to a request for communication movement output from the node 110 belonging to the communication mediation nodes 130 and 140. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
