Zusammenfassung P2P systems, which contribute a significant portion of today's Internet traffic, build their overlay topology largely agnostic of the Internet underlay. This leads to traffic management challenges for ISPs on the one hand, and potentially inefficient neighbourhood selection for P2P nodes on the other hand. To alleviate this problem, we propose a novel global Internet coordinate system, which can be used by P2P and other applications, to get estimates about path properties to potential neighbours/servers, both within and outside their ISPs. These estimates can be used, e.g., by P2P users to pick appropriate neighbours, so that both ISPs and P2P systems benefit. The coordinate system is built through ISP-P2P collaboration on the one hand, and collaboration between multiple ISPs on the other hand. In this paper, we also discuss which metrics can be provided by our coordinate system, and how it differs from existing coordinate systems.
