The share of peer-to-peer (P2P) protocol in the total network traffic grows dayby-
day in the Turkish Academic Network (UlakNet) similar to the other networks in the
world. This growth is mostly because of the popularity of the shared content and the
great enhancement in the P2P protocol since it first came out with Napster. The shared
files are generally both large and copyrighted. Motivated by the problems of UlakNet
with the P2P traffic, we propose a novel method for P2P traffic detection in the network
backbone in this thesis. Observing the similarity between detecting traffic that belongs
to a specific protocol and detecting an intrusion in a computer system, we adopt an
Intrusion Detection System (IDS) technique to detect P2P traffic. Our method is a
passive detection procedure that uses traffic flows gathered from border routers. Hence,
it is scalable and does not have the problems of other approaches that rely on packet
payload data or transport layer ports.
