<p>PURPOSE:To attain an efficient relay by providing a memory device storing an originating terminal address and an identification number in pairs. CONSTITUTION:At least three memory devices 5-1-5-3 storing the originating terminal address and the identification number in pairs are provided. Since the memory devices 5-1-5-3 are provided separately to input/output sections 3-1-3-3, it is possible to process each incoming packet equickly. If destination designation devices 6-1-6-3 cannot search an address AD1 coincident with an address AD2 from the corresponding memory devices 5-1-5-3, the packet is sent to all input/output sections except its own section via a connection network 8. The packet sent to the input/output sections 3-1-3-3 is sent to communication networks 1-1-1-3 to which each input/output section is connected. As the connection network 8, bus structure having a constitution not caused with collision normally is used.</p> |
