<p>PROBLEM TO BE SOLVED: To realize an efficient multicast communication capable of easily coping with the addition and elimination of nodes in a system in a wide area distribution system. SOLUTION: Each node 11 advises the other nodes constituting the system of a message ID to be received by its own node. The node receiving this message correlates the ID with the address of the generation source node, and stores them in a table 1103 of its own node. When transmitting the message, the ID of the message to be sent is discriminated, the address of the node to which the message is sent is discriminated on the basis of the table 1103 in which the ID of the message is correlated with the address of a node receiving the message having this ID, and the message is transmitted.</p> |
