Practical Modelling for Generating Self-Similar VBR Video Traffic

Abstract

Teletraffic in the Internet is rapidly growing and diversifying, and there is a strong need for QoS support in high-speed communication networks. There are a number of research issues concerning the transmission of JPEG/MPEG video over modern high speed computer networks. These problems have been studied intensively over the last ten years in order to provide a consistent and desirable QoS for JPEG/MPEG video traffic and utilise efficient resource allocation techniques. In the paper, we show that synthetically generated streams of VBR video, compressed under such standards as JPEG, MPEG-1 and MPEG-2, can be statistically equivalent to real video traces. We also investigate how compression algorithms on correlation structure of compressed teletraffic influence real video traffic.
