A Bandwidth Balancing (BWB) mechanism has been recently included in the IEEE 802.6 standard for Metropolitan Area Networks (MANs).BWB can provide,in overload network conditions,the requested bandwidth for the lightly loaded stations and evenly distribute the remaining bandwidth among the heavily loaded stations.However its operation requires some bandwidth loss.In this paper a new BWB mechanism for DQDB is proposed that does not waste any idle slots.For this reason it can converge faster,to the steady state,than the current BWB mechanism of DQDB.We analyze the throughput and delay performance of the proposed mechanism,under a single priority traffic class,and we compare it with that of the current BWB mechanism of DQDB.
