Paper Abstract

To efficiently utilize resources in broadband networks, we propose a control method for balancing work- and buffer- conserving service disciplines that is based on the use of prediction. Three key concepts are discussed in this study. First, it is noted that feedback control with a predictor can minimize buffer backlog. Second, it is proven that with a dynamic balance, the globally optimal bandwidth assignments for all virtual circuits can be determined by minimizing an appropriate cost function. Lastly, via trace- driven simulation, it is shown that assigning bandwidth based on this hybrid balance of work- and buffer-conserving service results in a reduction in cell loss when compared to a traditional work-conserving algorithm. The simulation traces were generated from an MPEG-encoded video.
