Abstract: The application of traffic smoothing algorithms(mainly WTS) in the context of developing a high-performance streaming server was studied.Two practical problems were analyzed and solved: one was to prevent the application of smoothing algorithm from bringing impacts on synchronization of audio and video streams on the client ends,and the other was to modify the sending plans produced by smoothing algorithms in order to make them applicable in RTP transferring.These two problems were studied and analyzed,and corresponding solutions and algorithms were presented and validated by experiments.
