Abstract

With the widespread deployment of broadband residential access networks and the development of media compression technologies, media streaming over the Internet has spread rapidly and attracted a large number of users and researchers. Currently, peer-to-peer (P2P) overlay networking is considered as a promising way to distribute large scale media streams over the Internet, due to the scalability, robustness, cost-effectiveness, and ease of deployment. However, there are still several fundamental questions: What is the maximum upload capacity utilization with minimum delay in the multi tree-based P2P streaming? How to maximize the peer's upload capacity utilization? What is the effect of peer out-degree on the upload capacity utilization? To address these problems, we investigate the effect of overlay topology and peer outdegree on the streaming delay and upload capacity utilization. Finally, we show that a carefully-designed overlay topology and peer placement strategy can achieve close-to-optimal delay bounds and upload capacity utilization on P2P streaming systems.
