Abstract

The Distributed Queue Dual Bus (DQDB) protocol is being considered by the IEEE 802.6 and ANSI T1S1.1 as an important component in their Metropolitan Area Networks (MAN) and Broadband ISDN User Network Interface (BI-SDN-UNI) standards respectively. This paper provides first a description of DQDB focusing mainly on its distributed queue operation. Then, the performance of DQDB under traffic saturation for the cases of concentrated and widely separated sources is studied and discussed with a special focus on the effect of the elimination of the STANDBY state on fairness and throughput. It is shown that the new version of DQDB, without the STANDBY state, provides better fairness than the previous one which include the STANDBY state. © 1990.
