<p>PROBLEM TO BE SOLVED: To continue communication even when use of a physical path is disabled by making communication with many job terminals with less resource. SOLUTION: A computer system 100' and relay severs 200a, 200b are interconnected by a plurality of physical paths, and each physical path is provided with physical path control means 111a-111c controlling communication using the physical path. The computer system 100' and each of job terminals 300a-300c are connected by a logic path for each job terminal obtained by dividing logically the physical path and each logical path is provided with logical path control means 121a-121c controlling the communication using the logical path. In the case of receiving data, a logical path selection means 122 gives data to the logical path control means controlling the logical path corresponding to the job terminal being a sender and in the case of data transmission, a physical path selection means 112 selects one of physical paths to be led to a destination job terminal and gives transmission data to the physical path control means controlling the selected physical path.</p> |
