%X All the early access mechanism based on contention or sequential access does not scale well to multi-gigabit per second rates or larger geographical coverage. Advances in laser and fiber optic technology have driven feasible link throughputs above a gigabit per second. Dynamic RAM chip have become cheap enough to be cost effective at providing the large amounts of buffering needed at these very high link speeds. Moreover, quick routing and MAC decisions are possible with current CMOS technology. In combination, these trends make it possible to construct a Practical LAN using multiple switches and gigabit per second point-to-point fiber links configured in an arbitrary topology. It's well known that the current technology trends make it possible to build high speed communication networks that can support high performance distributed computing. With increased data rates, the packet transmission time of a network could approach or even become less than the medium propagation delay. Performance of many network schemes degrades rapidly when the packet transmission time become small compared to the medium propagation delay. The use of high speed data rate alone is not sufficient, unless the medium access provides for efficient bandwidth use of the medium. This paper discusses and describes the performance characteristics of the most popular high speed networks such as DQDB, FDDI ,and ATM for Broadband Integrated Service Digital Network (B-ISDN), while carrying multimedia traffics and compare the performance evaluation results of the these networks with the results of the proposed high speed network namely EHABKIT. The comparative of the results confirms that the concept of pure packet switching for the EHABKIT architecture is almost equivalent to the high speed networks, DQDB, FDDI, ATM for B-ISDN, and its promising enough. .
