Abstract
A controller (node) divides all nodes connected to a network into several network groups, and gives the division network groups network identification numbers for identifying them. A token frame contains a network identification number. This network identification number enables data to be shared among all the nodes connected to the network while a token for each network group is circulated only in the network group.
