摘　　要：分析和解决了平滑算法应用过程中遇到的两个具体问题:(1)如何应用平滑算法使其不影响音频视频在拖动操作后的同步性;(2)如何将平滑算法得到的发送方案同RTP协议中关于视频数据打包的规定相融合。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.
