<p>PROBLEM TO BE SOLVED: To reduce a routing tag by combining and using a plurality of packet switches provided with different output route judgment methods. SOLUTION: The routing bits of input stage switches 110, 120, 130 and 140 are expressed by the sequence (0, 0), (0, 1), (1, 0) and (1, 1) of bit signals corresponding to output routes. Address display corresponding to output channels is provided in the routing tag and relay stage switches 210, 220, 230 and 240 distribute the output route corresponding to the OR of the address display for the respective output channels 71-1-71-4 and 74-1-74-4 housed by output stage switches 310-340 for the respective output stage switches 310, 320, 330 and 340. Further, the routing tag of packets inputted to the input stage switches 110-140 comprises the sequence of the bit signals corresponding to the output routes of the input stage switches 110-140 and the output address display of the output stage switches 310-340.</p> |
