Abstract

Grouping output channels in a shared-buffer ATM switch has shown to provide great saving in buffer space and better throughput under uniform traffic. However, uniform traffic does not represent a realistic view of traffic patterns in real systems. In this paper, we extend the queuing analysis of shared-buffer channel-grouped (SBCG) ATM switches under imbalanced traffic, as it better represent real-life situations. The study focuses on the impact of the grouping factor and other key switch design parameters on the performance of such switches as compared to the unichannel allocation scheme in terms of cell loss probability, throughput, mean cell delay and buffer occupancy. Numerical results from both the analytical model and simulation are presented, and the accuracy of the analysis is presented. Copyright © 2005 John Wiley & Sons, Ltd.
