PACKET DATA COMMUNICATION SYSTEM WITH RING TYPE TRANSMISSION LINE
摘要
<p>Packet data communication system includes a ring type transmission line for circulating a predetermined number of slots on which packets to be transmitted are loaded. Interface nodes are provided between the ring type transmission line for loading packets on slots and receiving packets from slots for terminals. In the interface node, there are a predetermined number of subtransmission lines, for passing each of the slots in parallel through the interface node. Terminal interfaces respectively having sending buffers for storing packets and receiving buffers for storing packets are provided as well as a switch for connecting each of the sending buffers and receiving buffers to any one of the sub-transmission lines.</p>
