REsource LOcation And Discovery (RELOAD) is a peer-to-peer signaling protocol that can be used to maintain an overlay network, and to store data in and retrieve data from the overlay. RELOAD is currently being standardized in the Internet Engineering Task Force (IETF). The main application using RELOAD is Peer-to-Peer Session Initiation Protocol (P2PSIP). In this paper, we study the performance...

Peer-to-peer file-sharing systems commonly use the set-of-terms model – the union of the terms in the shared files – to describe succinctly a peer’s shared files. This information is shared with neighbors who use it to guide query routing decisions. The problem with this model, however, is that it falsely suggests term cooccurrences that do not exist in any single file. Consequently, queries ge...

Peer-to-peer (P2P) technologies have been widely used for content sharing, popularly called “file-swapping” networks. This chapter gives a broad overview of content sharing P2P technologies. It starts with the fundamental concept of P2P computing followed by the analysis of network topologies used in peer-to-peer systems. Next, three milestone peer-to-peer technologies: Napster, Gnutella, and F...

At present, most peer-to-peer file sharing systems provide file-mark-based searching function. In the paper, we offer a file recommendation system based on pure peer-to-peer system, use the TOPK method to find similar interest peers in a way to realize the interest-based self-adaptive adjustment of network topology; and exploits the recommendation information between users with similar interest...

Peer-to-peer (P2P) services allow users to share networked resources, notably bandwidth and content, from the edges of the network. These services have been popularized because of file sharing — particularly the sharing of unlicensed copyrighted files. Concerns about such P2P file sharing were highlighted by content owners’ recent lawsuits against individual users and P2P network operators. How...

The term online peer-to-peer lending (P2P) describes the loan origination process between private individuals on online platforms were financial institutions operate only as intermediates required by law. Initialized by groups in online social networks, first commercial online P2P lending platforms started in 2005. Thus online P2P lending is a relatively young research field. This paper gives a...

We study the development of mobile peer-to-peer (MP2P) traffic and the usage of MP2P applications in Finland during 2005-2007. Research data consists of 1) traffic traces measured from three Finnish GSM/UMTS networks covering the Internet-bound mobile data traffic generated by 80-90% of Finnish mobile subscribers (N > 4,000,000), and 2) usage log files collected with a dedicated Symbian handset...

As Peer-to-Peer (P2P) quickly gains popularity for its nearly unlimited scalability, the amount of copyright infringing incidents surges even more rapidly. While record industry pleads for prohibiting P2P by lawmakers, academicians and practitioners turn to look for more constructive ways: using P2P as a profitable and legitimate distribution channel. By offering rebate to those who share conte...

In this paper, we propose an innovative system that aims to adapt to the user needs and preferences the media content transmissions within IP and P2P environments. To personalize the manner the content is displayed to the final user, this proposed network allows the transmission of multiple views and different layers for each media content piece. In addition, we suggest an approach on how to de...
