Rtp Protocol Qos Dynamic Feedback Control Of Research And Application

According as the technical of network, new network applications need new network protocols. So, the study of RTP used for real-time multimedia information is necessary.In this thesis, we first analyze the demand of the transmission of real-time multimedia information on network and the capabilities of the communication network that is used to transport real-time multimedia information. According that, the focus is put on the network protocols. Several network protocols, such as TCP, UDP, RTP/RTCP, are analyzed and contrasted thoroughly, and their concept and mechanism, their strengths and their flaws are also described clearly.In the studying of the quality of service control, we analyze each parameter draw on the package of sender or receiver in RTCP. By the size of the conversation, we introduce two methods of the step, judgment and the algorithm.Then, a real-time audio conversation system that can auto judge the network state and auto adjust the voice code over RTP/RTCP protocols is brought forward and illustrated. This system follows the C/S model and can loss the date package factitiously in the client.Programming by the Winsock, we put the design into execution. Finally, we give a foresight on the transmission of real-time multimedia information over RTP/RTCP.
