File transfer in high-speed token ring networks: performance evaluation by approximate analysis and simulation

A model of a multiple-token-ring backbone based on fiber-optic transmission, intended for LAN interconnection, is presented. Because it is one of the most important applications for inter-LAN communication, file transfer is selected for performance evaluation. A mixed traffic environment including interactive traffic is assumed. The suitability of multiple-token-access protocols is studied by approximate analysis and simulation, yielding results for both queue length and packet delay. Sensitivity with respect to medium length and station latency is considered. The results allow performance predictions for high-speed backbone networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
