A significant part of today's Internet traffic is generated by peer- to-peer (P2P) applications, used originally for file sharing, and more recently for real-time multimedia communications and live media streaming. P2P applications pose serious challenges to the Internet infrastructure; by some estimates, P2P systems are so popular that they make up anywhere between 40% and 85% of the entire Internet traffic [Karagiannis], [LightReading], [LinuxReviews], [Parker], [Glasner].

A Survey on Research on the Application-Layer Traffic Optimization (ALTO) Problem
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.
