However, few papers focus on the fine grained identification of P2P traffic. Affinity Propagation (AP) algorithm is brought to P2P traffic identification field for the first time and a novel method of identifying P2P traffic finely based on Hierarchical Weighted Semi-supervised AP (Hi-WSAP) algorithm is proposed, which is on the foundation of the Hi-WAP algorithm and absorbs the semi-supervised thought. The proposed method identifies P2P traffic in semi-supervised way by application employing only 10 fast computed traffic features. Experimental results using two datasets show this method achieves high identification accuracy and low time complexity, which provides a path to finely identify P2P traffic in real-time. Key words: Peer to Peer (P2P) /  Affinity Propagation (AP) /  Fine grained identification /  Semi-supervised clustering
