Abstract :
In this paper, we study the topic of distributed and optimal congestion control for scalable video streams in application-layer multicast (ALM). We propose a TCP-friendly, fully distributed synchronous algorithm based on the utility-price model which maximizes the global utilities for the streams in the application-layer multicast tree. With the help of numerical study, we show that our proposed algorithm optimizes the overall video quality for fine-grained scalable streams, while minimizing the messaging overhead in the application-layer multicast channel.
