Interconnection of CSMA/CD LANs via an N-port bridge

The interconnection of CSMA/CD LANs using an N-port bridge is considered. The stability and throughput-delay performance of the interconnected system is analyzed approximately by decomposing it into N consistent but otherwise independent LAN subsystems. The performance of a LAN subsystem with bridge priority is evaluated, and the results are used for the performance evaluation of the interconnected system. Simulation results indicate that the decomposition approach provides reasonably accurate performance prediction. The bridge interconnection system is compared to a system in which the bridge is replaced by a repeater, and the performance advantages of the former system over the latter are quantified
