ABSTRACT:
Multi-network system for transmitting data among a plurality of stations, each of which is connected to one of transmission lines, a plurality of said transmission lines being connected with each other through bridge stations, in which the numbers of the transmission lines, with which in final destination station and the source station are connected respectively, are set as the destination address and the source address in the data frame to be sent; in the case where the bridge station receives a frame of data to be relayed between different transmission lines, the bridge station identifies the relay by the destination address, stores the data frame in a memory means storing data, which should be sent by the bridge station itself; attaches to the data to be relayed a flag, in which the relay indication is set, and to the data not to be relayed a flag, in which the relay indication is not set; and when the data are sent by said station, in the case where the flag attached to the data represents the relay, the data frame which has been received is sent without any change.
