Paper Abstract

In this paper, a method of smoothing variable bit-rate (VBR) MPEG traffic is proposed. A buffer, which has capacity over the peak bandwidth of group of picture (GOP) sequence of an MPEG traffic and which output rate is controlled by the distribution of GOP sequence, is connected to a source. The degree of burst of output stream from the buffer is deceased, and the stream's autocorrelation function characterizes non-increased and non-convex property. For smoothed MPEG traffic stream, the GOP sequence is the element target source traffic using for modeling. We applied a marked renewal process to model the GOP smoothed VBR MPEG traffics. The numerical study of simulating target VBR MPEG video source with a marked renewal model shows that not only the model's bandwidth distribution can match accurately that of target source sequence, but also its leading autocorrelation can approximate the long-range dependence of a VBR MPEG traffic as well as the short-range dependence. In addition to that, the model's parameters estimation is very easy. We conclude that GOP smoothed VBR MPEG video traffic could be not only transferred more efficiently but also analyzed perfectly with a marked renewal traffic model.
