Abstract:

When multimedia traffic is transported over a network, video traffic, though usually compressed/encoded for bandwidth reduction, still consumes most of the bandwidth. In addition, compressed video streams typically exhibit highly variable bit rates as well as long range dependence properties, thus exacerbating the challenge in meeting the stringent QoS requirements of multimedia streaming with high network utilization. Dynamic bandwidth allocation in which video traffic prediction can play an important role is thus needed.

A delay guaranteed bandwidth allocation is proposed based on buffer monitoring and the fast non-linear adaptive prediction. The goal of this scheme is to meet the stringent QoS requirements with acceptable network utilization. Simulation and analytical results demonstrate that this scheme provides guaranteed delay and achieves high bandwidth utilization.
