摘要：

Most of the MAC sublayer protocols recently proposed for application in very high-speed local and metropolitan area networks are based on a slotted transmission scheme. Slotting guarantees very good throughput efficiencies, but further gains are possible if slots can be freed after reaching their destination, thus being available for repeated use as they propagate in the network. The paper describes a simulation-based quantitative analysis of the performance gains obtained by introducing slot reuse in DQDB and CRMA. CRMA-II, the latest evolution of CRMA naturally incorporates slot reuse in the MAC protocol operations, and is considered in the study for comparison purposes. In the case of the standard DQDB protocol, some existing proposals are considered. In the case of CRMA, both a previous IBM proposal and a novel approach, leading to very good performances, are studied.
