PURPOSE:To decrease the transmission cue of a node by providing a transmission cue to wait for transmission data to nodes other than the own node and individual transmission cue storing the transmission data at each transmission destination node only at a fualt of the transmission destination node. CONSTITUTION:Transmission data 11A, 12A, 13A, 14A transmitted to other nodes 11, 12, 13, 14 from a node 10 are stored in the transmission cue. Head data 11A of the transmission cue is extracted from the transmission cue and transmitted to a loop form common transmission line and when the node 11 is buffer-busy or a faulty and no reception response is returned from the node 11 to the node 10, the transmission data 11A is stored in the individual transmission cue 11. Then the next transmission data 12A stored in the transmission cue is extracted and transmitted from the node 10 to the node 12. When the reception response is returned, the transmission data 12A is erased and the next transmission data 13A stored is extracted and transmitted from the node 10 to the node 13. |
