Discrete-time analysis of a finite buffer with VBR MPEG video traffic input

Currently, a lot of interest is paid to multimedia traffic in general and to video traffic in particular. Most of the studies deal with appropriate models for this complex type of traffic and use trace-driven simulations to assess the performance of high-speed networks carrying this type of traffic. In contrast, we develop two models of different correlation complexity and apply them in a discrete-time analysis of a buffer with variable bit rate (VBR) MPEG video traffic input. The algorithms are easy to implement and provide good cell loss estimates over a wide range of buffer sizes.
