As Peer-To-Peer (P2P) systems are widely deployed in the Internet, P2P traffic control becomes a challenge for Internet Service Providers (ISPs) and P2P system vendors. Some recent works consider the interaction between ISPs and P2P systems and propose ISP-friendly P2P traffic control mechanisms for reducing cross-ISP traffic. In this paper, the authors consider another fundamental problem: The interaction among multiple coexisting P2P systems. Specifically, they propose an ISP-friendly inter-overlay COOrDination framework (COOD) for controlling P2P traffic, which consists of three important components: Network traffic optimization, overlay service differentiation, and ISP policy enforcement.
