This paper surveys research and standards in high-speed networks. It first classifies high-speed networks according to the area of coverage. Secondly, it discusses the switches. Then, it examines network management protocols: media access control, routeing, flow control and error control. Finally, it investigates current hig-speed network standards: DQDB, FDDI, ATM, and SONET.(d) low error rate (e) abundant bandwidth Owing to the above factors, the architecture and protocols of high-speed networks have the following features:1. Simple algorithms. Since the time available for processing the packets is limited, the network protocols should be simplified as much as possible so as to reduce processing overhead, and the frequency of executing the protocols. . End-to-end protocols.As the number of users in the network is increased by orders of magnitude, it is desirable to shift the processing from the internal nodes of the network to the edge nodes (the end nodes for information transport). . Regular topologies.Regular network topologies simplify routeing, thus reducing network processing. Some regular topologies provide a number of alternative paths between the source and the destination, rendering the network less susceptible to failures. Limiting buffering.In high-speed networks, a large number of packets will flow through the transmission links. Thus, it is impractical to provide enough buffers to store all of them. In addition, current technology requires an optical-to-electrical conversion for buffering packets, which further increases processing overhead. Simplified error control.The error rate of a fibre-optical system is extremely low. This means that end-to-end, forward error control will be preferred over hop-by-hop, feedback control protocols. . Trade-offs between bandwidth and delay.The bandwidth in a high-speed network is not a scarce resource. This creates the opportunity to use some algorithms which squander bandwidth to achieve better performance. . Vulnerability to failures.The large bandwidth of high-speed networks allows many communication connections on a single fibre. Any failure in network hardware or software may cause chaos. Therefore, incorporating reliability features in high-speed networks is crucial. NETWORK ARCHITECTURENetworks may be categorized by their geographical coverage. We distinguish between local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN):

“…Video is often considered to be the critical element in bringing fiber all the way to subscribers and to completely dominate all other potential high bandwidth subscriber applications [71], [75]. That is, it is the only service seen as having a high interest in the residential market, for which the high bandwidths of fiber are needed.…”
