A study of P2P traffic localization by network delay insertion

Abstract

In this paper, we examine a new kind of P2P traffic localization approach exploiting the peer selection adaptation (i.e., preferring peers who are likely to provide better performance), called Netpherd. Netpherd tries to affect the peer selection adaptation to localize the P2P traffic by manipulating the network performance. To manipulate the network performance, Netpherd adds an artificial delay to inter-domain traffic going to target peer. Evaluation results show that Netpherd localizes the P2P traffic while improving the content download performance.
