The current IEEE 802.6 standard has defined the distributed queue dual bus (DQDB) as the subnetwork for metropolitan area networks (MAN). However, this standard leaves some latitude in the possibility of slot multiuse. This paper addresses the issue of DQDB network delay performance when special devices called erasure nodes are employed with or without the so-called slot preuse technique, which has been proposed recently. It is shown that introducing this technique into DQDB networks dramatically improves system performance in terms of average segment delay and maximum throughput, especially when there is some locality in traffic patterns or the network consists of a small number of nodes.
