Dynamic bandwidth allocation for VBR video transport

Souhwan Jung, Younghan Kim, James S. Meditch

Abstract

We discuss a source model for VBR video traffic, and present an application to dynamic bandwidth allocation of the model. A two-state Markov chain model is used to extract useful parameters for adaptively allocating transmission bandwidth to variable-bit-rate traffic. The performance of our dynamic bandwidth allocation scheme has been compared with other schemes for both a homogeneous and a heterogeneous mix of traffic. Simulation results show that our dynamic bandwidth allocation scheme outperforms the static allocation or the low-pass filter scheme.
