Abstract

In this paper, we study the bandwidth allocation problem for an ATM multiplexer loaded with compressed VBR video sources. To estimate the bandwidth required by a VBR video source, we characterize its traffic by five parameters: peak rate, bottom rate, mean rate, standard deviation, and the coefficient of the autocorrelation function. The aggregate traffic of a number of VBR video sources is modelled by a discrete-time Markov modulated deterministic process (D-MMDP) which is approximately equal to the superposition of a number of identical and independent two-active-state mini-sources. Based on the effective bandwidth approach and the Gaussian approximation, we derive simple formulas for estimating the required bandwidth
