DQDB: a fast converging bandwidth balancing mechanism that requires no bandwidth loss

A bandwidth balancing (BWB) mechanism has been included in the IEEE 802.6 standard for metropolitan area networks (MANs). A new BWB mechanism for the distributed queue dual bus (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 the DQDB. The authors analyze the throughput and delay performance of the proposed mechanism under a single priority traffic class and compare it with that of the current BWB mechanism of the DQDB.<
