Abstract
The Fiber Distributed Data Interface (FDDI) and the IEEE 802.6 Distributed Queueing Dual Bus (DQDB) are emerging standards for high-speed (45-150 Mb/s) local and metropolitan area networks. Several ways of building on these emerging standards to significantly increase the achievable throughput and lower the end-to-end delay are described. Without increasing the number of transceivers or their rate, substantial throughput increases are obtained by a highly concurrent logical interconnection pattern of user nodes, and the end-to-end delay is decreased by the use of more efficient media-access techniques. The most promising architecture is a multiconnected ring having only two transmitters and two receivers per node, where each node needs to handle or process only a small fraction of the network traffic. In one example, a 24-node, distributed, packet-switched network, with only two 100-Mb/s transmitters and two 100-Mb/s receivers per node, that has a throughput of 1.5 Gb/s (15 time the throughput of FDDI) is described. Such a system has the potential to be a follow-on standard to FDDI (or IEEE 802.6) or to provide a high-performance local/metropolitan area network that can interwork with standard systems.
