Internet Research Task Force (IRTF) E. Marocco Request for Comments: 6821 A. Fusco Category: Informational Telecom Italia ISSN: 2070-1721 I. Rimac V. Gurbani Bell Labs, Alcatel-Lucent December 2012 Improving Peer Selection in Peer-to-Peer Applications: Myths vs. Reality Abstract Peer-to-peer (P2P) traffic optimization techniques that aim at improving locality in the peer selection process have attracted great interest in the research community and have been the subject of much discussion. Some of this discussion has produced controversial myths, some rooted in reality while others remain unfounded. This document evaluates the most prominent myths attributed to P2P optimization techniques by referencing the most relevant study or studies that have addressed facts pertaining to the myth. Using these studies, the authors hope to either confirm or refute each specific myth. This document is a product of the IRTF P2PRG (Peer-to-Peer Research Group).
