<p>PURPOSE:To enhance the multiple access function of a packet and the exchange in the unit of packets by providing a packet storage circuit to a node of a switch and a contention circuit at each line respectively so as to allow the node itself to apply independent execution of exchange. CONSTITUTION:A reception circuit 301 of the storage circuit 300 receives a packet from a terminal equipment 100 via a packet line 10 and stores it into a memory 304. A transmission circuit 30 sends a packet in the memory 304 to a terminal equipment 200 through a line 20. An analysis circuit 303 compares an address part of the packet in the memory 304 with that of itself and informs it to a control circuit 305 when they are coincident. In receiving the coincidence notice from the circuit 303 to the circuit 305, the contention control circuit 400 starts the transmission circuit 302 and sends a packet to the terminal equipment 200 via the line 20. Other storage circuits 310, 320 ... have similar functions.</p> |
