PURPOSE:To make the network communication processing efficient and to allow the system to cope flexibly with other communication pattern by providing a switch box or the like having a distributer and a concentrator to eliminate the need for the control by a centralizing controller. CONSTITUTION:Each node 50 is provided with plural switch boxes 51 (one box only is shown in the figure) and a hand-shake section 52 synchronizing message transmission reception. Moreover, an input section of each box 51 is provided with distributers 53-1-53-3, and an output section is provided with concentrators 54-1-54-3. Moreover, each distributer 53 and each concentrator 54 are provided respectively with a message passing detection section and in the case of message passing, a message end tag at the tail end of a message detects the message passing. Then the connection state of a 2-branch distribution switch in each distributer 53 or a 2-branch merger in each concentrator 54 is switched. Thus, the control by the centralized type controller is not required, the communication processing of the network is made efficient and the system copes flexibly with other communication pattern. |
