PERFORMANCE ANALYSIS OF INTERCONNECTED LANS WITH SERVER CLIENT CONFIGURATION

In this paper, we study the end-to-end performance of interconnected local area networks (LAN) with server/client configuration. The system uses bridges to connect two token-ring LANs through a high-speed communication link. A server station located on one LAN receives requests from client-stations on the same LAN as well as on the remote LAN. processes the requests, and returns responses to the client-stations. The end-to-end connections of the interconnected network are modelled as single-chain and multiple-chain closed queueing systems, which are solved by an iterative algorithm based on the MVA (mean value analysis) method. The performance examples are shown in terms of various system parameters such as the window size, server processing speed and internetwork transmission capacity, and are verified by computer simulations.
