  "abstract": "A significant part of the Internet traffic today is generated by peer-to-peer (P2P) applications used originally for file sharing, and more recently for real-time communications and live media streaming.  Such applications discover a route to each other through an overlay network with little knowledge of the underlying network topology.  As a result, they may choose peers based on information deduced from empirical measurements, which can lead to suboptimal choices.  This document, a product of the P2P Research Group, presents a survey of existing literature on discovering and using network topology information for Application-Layer Traffic Optimization.  This document is not an Internet Standards Track specification; it is published for informational purposes.",
