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 destina
tions. From establishing and solving the main equations governing the
behaviour of the bridged networks. the effects of design parameters su
ch as the bridge buffer size and re-transmission backoff delay on the
performance of the system are studied. It is shown that if these param
eters are chosen properly, better throughput and delay performance can
be obtained. when compared with an equivalent CSMA/CD network without
using a bridge.
