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. Finally, the performance with variable bit rate video traffic is examined by simulation for a small DQDB network whereby a comparison of performance results between DQDB with and without STANDBY is presented.
