Abstract

A fixed frame-based distributed queue dual bus (FB-DQDB) medium access protocol was previously proposed (P.C. Wong, 1991) for gigabit-per-second local and metropolitan area networks (LANs and MANs). This protocol allows each station to transmit a number of consecutive slots up to the limit of a frame size. The protocol is extended by allowing the headend to modify the frame size dynamically according to the request traffic. The new dynamic frame-based DQDB protocol (DF-DQDB) can therefore give a better throughput performance for variable size messages. Various performance aspects of this protocol are studied through simulation
