PERFORMANCE ANALYSIS OF 2 BRIDGED CSMA CD NETWORKS

This paper analyses the performance of two non-persistent CSMA/CD LANs linked by a bridge. The main function of the bridge is to buffer all internetwork packets and forward them across networks to their destinations. From establishing and solving the main equations governing the behaviour of the bridged networks. the effects of design parameters such as the bridge buffer size and re-transmission backoff delay on the performance of the system are studied. It is shown that if these parameters are chosen properly, better throughput and delay performance can be obtained. when compared with an equivalent CSMA/CD network without using a bridge.
