Abstract

In recent years, peer-to-peer (P2P) file sharing applications (e.g., eMule) have dominated the Internet. eMule deploys its distributed network (i.e., KAD) based on Kademlia, a robust distributed hash table (DHT) protocol, to facilitate the delivery of content. In this paper, we conduct a series of analyses on the social network of KAD which is formed based on the information of how peers share files in KAD. Our analyses reveal many interesting characteristics of KAD. We further discuss the uses and misuses of these characteristics. Especially, we propose a novel approach to improve the routing performance of KAD based on the characteristic of its community structure.
