Abstract

We study modeling approaches for traffic characteristics of real time video traffic including the distribution function of the size of each group of pictures in MPEG coding and their short term correlation. A numerical solution of the steady state workload distribution is computed for semi-Markovian state models in discrete time. A verification step based on interval arithmetic is able to enclose the numerical result within tight bounds for many cases. We compare the delay and loss performance in data forwarding by a buffered switch as predicted by the model to direct evaluation of publicly available video traces.
