PURPOSE:To improve the throughput of a network by providing d<k> unidirectional ring type transmission lines (d, k: natural number >=2) in the same direction and providing nodes set by being connected to (d) ring type transmission lines selected by the nodes from the d<k> ring type transmission lines by a specific procedure. CONSTITUTION:Binary display numbers [000]-[111] are given transmission lines 20-27 in order and two transmission lines which differ in only 1st low digit are selected among the binary notation transmission lines 20-27 to set the 2nd stage of nodes. Then two transmission lines which differ in only 2nd low digit are selected among the transmission lines 20-27 to set the 2nd stage of nodes, and two transmission lines which differ in only 3rd digit low are selected among the transmission lines 20-27 to set the 3rd stage of nodes. Thus, noises in the connection forms of the 1st-3rd stages are set on the trans mission lines cyclically to constitute the network. Consequently, the throughput is improved. |
