Abstract

The feasibility of proactive congestion controls for the support of real-time variable bit rate services on wideband-broadband networks with large bandwidth delay products, e.g. broadband satellite networks, is examined. The method is based on congestion anticipation which is made possible due to correlations that multimedia traffic exhibits. We have used realistic models for traffic in low-earth-orbit, medium-earth- orbit and geosynchronous-earth-orbit satellite systems. It has been shown that the approach is effective; this indicates matching of the time-scales of these correlations with the delays involved.
