Abstract：With the progress of theoretical and applied research, multimedia network communications at an unprecedented pace, the traditional protocol can not meet the requirements of real-time multimedia network communication. Audio data transmission on the network demanding real-time, high reliability, if you use the TCP protocol can not meet the real-time requirements. This paper describes a real-time transport protocol RTP, and gives the protocol used for real-time transmission of audio data and methods of the implementation process. Avoid the use of traditional TCP protocol for voice communications shortcomings of poor real-time, reduced network latency, and improve voice transmission quality.
