Latency analysis of ISP-Aware P2PTV system

In Peer-to-Peer TV (P2PTV) systems, end users attempt to download media from other end users instead of servers. This policy offloads work from IPTV servers and improves the scalability of the system significantly; however, this approach increases inter ISP traffic dramatically. This paper presents a distributed mechanism to reduce the heavy inter-ISP traffic in P2PTV. This mechanism penalizes those end users which download media data from other end users outside their neighborhood. We study the impact of such situations on the inter-ISP traffic and the latency of media streaming in P2PTV.
