With the success of P2P file sharing, new emerging P2P applications arise on the Internet for streaming content like voice (VoIP) or live video (IPTV). Nowadays, there are lots of works measuring P2P file sharing or P2P telephony systems, but there is still no comprehensive study about P2P IPTV, whereas it should be massively used in the future. During the last FIFA world cup, we measured netwo...

Peer-to-Peer (P2P) content sharing systems have experienced an explosive growth, and now dominate large fractions of both the Internet users and traffic volume. However, due to the self-organization and self-maintenance nature of P2P overlay networks, these systems are vulnerable to the content pollution, where attackers aggressively inject a large quantity of polluted content into the systems....

This paper discusses the ongoing work on P2P Wikipedia, a prototype of a personalized tag-based navigation system for Wikipedia content. It is the first open source peer-topeer (P2P) file sharing system able to deal with large files like video content that is being scaled to HTML content as well. The combined techniques in our prototype are the automated calculation of tags from HTML content, a...

In the last few years, the success of the Napster online music sharing program has drawn much attention to an emerging paradigm for communication on the Internet namely Peerto-Peer (P2P) technology. In P2P, file sharing is probably the most popular application. But in fact, computers in P2P networks or peer nodes can share various types of data and resources, i.e. files, bandwidth, storage spac...

Peer-to-Peer file sharing networks have gained tremendous popularity in recent years. However, traversing Network Address and Port Translators (NAPT) may still fail in certain topologies. In this paper, we present Programmable Port Forwarding, a lightweight approach for allowing private hosts to fully participate in a Peer-to-Peer network. By extending the NAPT that a private host uses to conne...

The computer world is experiencing a paradigm shift towards context-aware pervasive computing, where diverse computer devices communicate with each other through different network access technologies, and allow resource access based on user preferences. P2P computing is an area which will be affected by this new trend. In this paper, we proposed a resource replication strategy for context-aware...

Today, a large part of the traffic carried by the Internet is generated by file-sharing applications based on the P2P paradigm. Moreover, P2P traffic has particular features, quite different from the ones generated by "classical" data applications, and generally causes highly dynamic and distributed traffic matrixes that heavily stress network infrastructures. With this respect, it is reasonabl...
