Evaluation of a cell loss rate computation method in ATM multiplexers with multiple bursty sources and different traffic classes

The aim of this paper is to test the effectiveness of a method for the computation of the cell loss rate in multi-source and multi-traffic class ATM multiplexers. Different models to describe a bursty on-off source are presented, which are based on Markov chains, whose complexity is increasing with the accuracy of the description. Moreover, one of these models is extended to compute the cell loss rate in an ATM multiplexer under a traffic mix, composed first by the superposition of multiple homogeneous sources, and then of multiple sources of different traffic classes. The model accuracy is analyzed by numerical and simulation results
