B-ISDN을 경유한 LAN간 접속 IWU 기능에 관한 연구

A study on IWU functions interconnecting LANs via B-ISDN

In this paper, we propose the protocol stact and the server functions of IWU which interconnects distributed LAN's users by using of B-ISDN. The protocol stact of interconnecting IWU under consideration users TCP/IP in upper layer. TCP/IP is popular communication protocol in interconnecting distributed LANs. The interconnecting IWU has server functions for transfering datagrams to B-ISDN such as address translation, fragment and reassembly, CL server, signalling and traffic control. We analyze the performance ofinterconnecting IWU with M/M/1/K queueing model and obtain the throughput and buffer size of interconnecting IWU.
