PROTOCOL TERMINATOR, PROTOCOL TERMINATION METHOD, PACKET TRANSMISSION SYSTEM AND PACKET TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technology that effectively utilizes a band width with which each communication network transfers data in a network consisting of communication networks with different transmission rates by enhancing the throughput for packet transmission. ;SOLUTION: Protocol terminators 7, 8 are placed on the way of a packet transmission path between communication networks with different transmission rates, terminate a layer 3 protocol of open system interconnection OSI 7 layer structure of a packet on behalf of the destination in the case of receiving a packet of the desired destination, convert the packet into a layer 4 packet and provides an output of it, and transmit the outputted layer 4 packet to the destination of this packet.;COPYRIGHT: (C)2000,JPO
