Interception of P2P Traffic in a Campus Network

Merouane MEHDI


Nowadays, many universities face bandwidth saturation problem caused by several origins. These include youtube abusively use, online games and especially illegal downloading that makes havoc to Peer-toPeer protocol e.g. BitTorrent. The latter is often associated with data piracy and copyright violation. This article aims at presenting on one hand the impact of the use of Peer-to-Peer file sharing traffic on campus bandwidth by observation of BitTorrent traffic and on the other a method for limiting the illicit access to this kind of networks. For this purpose, we used a set of open source tools like wireshak sniffer software to capture Bitorrent traffic. Additionally, using the well-known Snort intrusion detection system with a number of adequate and new rules one can reduce bandwidth saturation problem. This solution allowed in our case, a bandwidth saturation reduction of 35%.
