Abstract

The distributed queue dual bus (DQDB) is the draft of a standard proposed by the IEEE 802.6 Working Group on metropolitan area networks (MANs). This proposal has been criticized because the network control information is subject to propagation delays that may be much longer than the transmission time of a data segment. As a result, the protocol for dynamic bandwidth allocation suffers from asymmetric access properties. It is shown that both throughput and delay may be decisively affected by the geographic location of a station with respect to other users. On the other hand, DQDB yields fair medium access for many realistic scenarios
