The composition and characteristics of real-time transport protocol (RTP) for voice is firstly discussed in this paper. According to RTP protocol and its related functions, in the Windows environment it uses WinSock (Windows Sockets) and multimedia library provided by Windows SDK to realize the implementation of RTP/RTCP protocol, and apply Visual C++ to design a real-time voice transmission software, it can achieve point-to-point voice communication. At last, the article analyses the data structures of program that uses two-way linked list and single buffering to avoid the complexity of multi-level buffering and dynamic release/allocate memory.
