Abstract

A frame-based distributed queue dual bus (FB-DQDB) medium access protocol was proposed by P.C. Wong (1991) for Gbit/s local and metropolitan area networks that allows the consecutive transmission of slots up to the limit of a packet size. However, it could only attain 81% of the maximum throughput for variable size messages. The authors discuss a frame-based priority scheme for the FB-DQDB protocol. Traffic can be classified as those which need consecutive transmission (p-traffic) and those which do not (s-traffic). Since delay-sensitive traffic (e.g. voice and video) is mostly s-traffic, the priority scheme includes this traffic in the FB-DQDB protocol and increases the maximum throughput to 100%
