PURPOSE:To decrease the number of times of copied data to be sent to one and same node by allowing the node at a branch point to copy the data. CONSTITUTION:Object terminal information in a data received by a node 23 and a destination information table 11 of the node 23 are retrieved by an information table retrieval means 12 and when it is judged that the transmission to plural destination nodes is required, a data copying means 13 copies the data and the object terminal information is revised for each destination node, and sent to each node 23. Since the data sent from a sender terminal 21 is copied at each node 23 when the destination node to the object terminal 21 differs, the number of times of the transmission of the copied data in the multiple address communication is decreased.
