Abstract

The performance of two high speed network protocols, IEEE 802.6 distributed queue dual bus MAN and fiber distributed data interface are compared based on their ability to support integrated traffic. The comparison includes the asynchronous priority characteristics of the two protocols as well as the performance characteristics of their isochronous service classes. In the integrated network considered, voice stations are assigned to the isochronous class of both protocols. Video sources, which are models of video CODEC systems for ATM environments, are given the highest priority of the asynchronous class for both protocols. The asynchronous data traffic is distributed equally among three asynchronous classes. The two protocols are then compared on the basis of their throughput, delay, network utilization, and fairness
