Performance analysis of the medium access control protocol of the FDDI token ring network

Abstract

Presents results for the voice-data performance of the medium-access-control protocol selected for the FDDI (fiber distributed data interface) network. This protocol can provide priority services to different types of traffic, as well as guarantee bounded delays for real-time applications. The constraints that the system parameters must obey to provide bounded delays for the voice packets are derived. Simple analytic formulas are derived that accurately predict the data packet waiting times. The effect of various system parameters on performance is investigated. Finally, the impact of relaxing the constraints imposed by the voice-delay bound, by allowing clipping, is considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
