Traffic engineering and admission control schemes for QoS support over the Internet share the hypothesis that offered traffic must be policed. Recently, measurement-based techniques have been proposed as effective QoS-guarantee mechanisms. For them, a key element is a thorough understanding of the characteristics of regulated traffic. In this paper, we present an analysis of the traffic output process for a leaky-bucket-regulated voice source with silence suppression, which would be a prime candidate for VoIP service. Specifically, we present a procedure for calculating the mean and the variance of the amount of regulated traf?c as a function of the measurement period. We evaluate the quality of our results via simulation.
