Executive Summary

PeerWise is an Internet routing overlay that reduces end-to-end latencies by allowing peers to forward through a relay instead of connecting directly to their destinations. Fundamental to PeerWise is the notion of peering agreements between two peers, wherein they agree to forward for one another. In this paper, the authors consider the problem of motivating users to establish and maintain peerings in a completely decentralized, scalable manner. They show that routing overlays present unique challenges and goals. For instance, since participants can always "Fall back" on standard Internet routing, They must encourage users to stay in the system and maintain long-lived peering agreements.
