Recognition of Real-time Transport Protocol is the premise and basis of the streaming media QoS management and security policy,but compared to other network protocol,there's quite hard to identify of RTP flow for that neither well-known port nor known signature is available.This paper summarizes the network flow classification technique and analyzes the RTP protocol in detail.Two approaches based on different strategies are proposed.The experimental result of use the proposed mechanisms are presented.It shows that the two new algorithms are effective in the certain accuracy and performance requirements.
