Abstract

Video streaming is becoming an increasingly important part of the present Internet. To guarantee a high-quality streaming environment to end users, many video applications require a strict form of network QoS that is not available in the present Internet. Thus, to supplement the best-effort model of existing networks, we study a new video streaming framework that allows applications to mark their own packets with different priority and use multi-queue congestion control inside routers to effectively drop the less-important packets during buffer over-flows. We describe priority AQM algorithms that provide "optimal" performance to video applications under arbitrary network loss and study a variation of Kelly's congestion control incombination with our framework. We call the combined architecture PELS 驴 Partitioned Enhancement Layer Streaming.
