Abstract: Locality promotion in P2P content distribution networks is currently a major research topic. One of the goals of all discussed approaches is to reduce the interdomain traffic that causes high costs for ISPs. However, the focus of the work in this field is generally on the type of locality information that is provided to the overlay and on the entities that exchange this information. An aspect that is generally neglected or only shortly addressed is how this information is used by the peers. In this paper, we consider the predominant approach of Biased Neighbor Selection and compare it with an alternative locality aware peer selection mechanism, Biased Unchoking. We show that both mechanisms complement each other for the BitTorrent file sharing application and achieve the best performance when combined.
