MULTI-ADDRESS COMMUNICATION PROCESSING SYSTEM

PURPOSE:To avoid giving a great load to a computer system by activating transmission by several times of an address based on routing information by including the number of addresses which shows the number of transmission destinations, and address identifications by the number of addresses, in the routing information of an inter-task communication message and activating transmissions for times of the number of addresses based on the routing information by a transmission processing task. CONSTITUTION:A data communication system consists of a self-computer system (self-system) 1 to transmit data, plural work stations 21 to 2m ((m) is a positive integer) provided under the self-system 1, and another computer system (another system) 4 connected with the self-system 1 through a network 3. Here, a work processing task 11 includes the number (n) of addresses and address identifications A1 to An for the number of addresses in the routing information, makes a transmission request, a transmission processing task 12 activates the transmissions for the times of the number of addresses based on the routing information and executes a same sending processing. Thus, the load of the computer system can be reduced.
