Abstract

This paper proposes an extension of the Distributed Queue Dual Bus (DQDB) protocol called Controlled Bandwidth (CB) DQDB which satisfies various fairness criteria and achieve 100% channel utilization. The protocol can serve both light and heavy load instances. Under heavy load, the protocol allocates bandwidth to each node, according to the ratio of each nodal arrival rate to the total arrival rate. Under light load, the protocol assigns to each node its required bandwidth. Simulation results show that the CB DQDB protocol has no unfairness problem. CB DQDB converges faster than the famous Bandwidth Balancing
