Quality of Service in Peer-to-Peer IPTV Networks

In Peer-to-peer (P2P) IPTV networks, jitter rate is one of the most important metrics for Quality of Service. In this paper, we develop a new approach to estimate jitter rate during playback. Unlike traditional approaches that focus on the download speed, our method relies on the distribution of peer download latencies. We demonstrated how to apply the proposed methodologies in a real-life environment. We report simulation results over a P2P IPTV network with 5 seeds and 2,000 clients. Experimental results not only validated the theoretical projections, but also show that our model captures impacts of many design factors. It is thus suggested to use the proposed method as a guiding tool to design P2P IPTV networks with low jitter rate.
