One way to combat P2P file sharing of copyrighted content is to deposit into the file sharing systems large volumes of polluted files. Without taking sides in the file sharing debate, in this paper we undertake a measurement study of the nature and magnitude of pollution in KaZaA, currently

Of the many P2P file-sharing prototypes in existence, BitTorrent is one of the few that has managed to attract millions of users. BitTorrent relies on other (global) components for file search, employs a moderator system to ensure the integrity of file data, and uses a bartering technique

Abstract—Motivated by P2P file transfer applications (e.g., BitTorrent) on the Internet, this paper considers the problem of delivering a file from a server to multiple receivers in a P2P network. Each receiver has an associated delay in receiving the file. We aim at understanding the optimal delay

mobile phones enable people to surf the web and read their mails wherever they are. However, for some reason, mobile peer-to-peer net-works have yet to manifest themselves. This paper studies the special requirements of mobile peer-to-peer (P2P) file sharing. We discuss how the limited resources

Abstract — This paper describes the Open P2P tracing system which aims to improve the research community’s understanding of P2P file sharing systems by providing continuous and up-todate traffic data which is anonymized and made freely accessible to all interested parties. It is our hope

In this paper we present a P2P file-sharing architecture optimized for mobile networks. We discuss the applicability of current P2P resource access and mediation techniques in the context of 2.5G/3G mobile networks. We investigate a mobile P2P architecture that is able to reconcile

P2P file-sharing poses a number of problems for system administrators including unpredictable network usage, increased vulnerability to security threats and the danger of legal action. Due to these problems, many businesses take measures to restrict the use of P2P software, but how successful have

Peer-to-peer (P2P) file-sharing applications generate a large part of today's Internet traffic. The large volume of this traffic (thus high potential caching benefits) and the large cache sizes required (thus nontrivial costs associated with caching) only underline that efficient cache

Currently there are a lot of public P2P file sharing networks in existence. Some of them have millions of users. There is a need for a system that can search and download from every P2P network. This article describes a novel structured interconnection system that works over multiple unstructured P
