Delay-insertion-based P2PTV traffic localization using AS-level topological information

Most P2PTV systems select a neighbor peer in an overlay network by RTT or a random method without an underlying network consideration. Streaming traffic is shared on network without localization awareness, which is a serious problem for Internet Service Providers. In this paper, we present a novel scheme to achieve P2PTV traffic localization by inserting additional delay into P2P streaming packets. The additional delay length depends on the AS hop distance between the viewer and neighbor peer, which represents a realistic network topology distance. The results of our experiments is conducted in a real network show that our proposed scheme can perform efficient traffic localization of P2PTV applications.
