The Design and Implementation of RTSP/RTP Multimedia Traffic Identification Algorithm

In recent years, multimedia traffic has been growing rapidly in the network, and it is of great significance to effectively supervise and manage multimedia traffic. This paper not only analyzes some specific multimedia transmission protocols, but also studies their communication characteristics. We proposes a multimedia traffic identification framework as well, which has a great advantage in scalability. In addition, multimedia traffic identification algorithms for specific RTSP, RTP/RTCP traffic, which have high identification accuracy, are described and validated in this paper. More importantly, a solution is put forward, aiming to solve the problem that the start and end of the stream cannot be determined when the multimedia stream adopts UDP transmission.
