P2P Traffic Identification Based on NetFlow TCP Flag

Abstract

P2P flow identification is the precondition of flow control in large-scale network. For the limited practicality existing in P2P flow identification method based on flow characteristic, a novel P2P traffic identification method based on NetFlow TCP Flag is proposed which classified traffic as P2P flow or non-P2P flow. Experiments prove that the method can detect P2P flow very effectively in large-scale network.
