P2P traffic inspection and identification based on Transport Layer

With its own unique advantages, Peer-to-peer (or P2P) system has gained tremendous momentum in recent years. Their applications become more and more extensive. P2P is used in large-scale, which has facilitated the development of the technology used in network and challenged the use of network bandwidth. Particularly, the application of large-scale audio/video rile sharing system and software based on P2P consumes a large fraction of bandwidth resource, and even causes network congestion and decrease of the performance of other businesses. Thus, to ensure the Quality of Service of other normal businesses, a reliable method of inspecting and identifying P2P flows and controlling the consumption of network bandwidth of P2P flows is highly demanded in this paper, we proposed a novel method which can inspect and recognize the P2P traffic based on Transport Layer. With the method, we can control P2P traffic more efficiently.
