With the development of image processing and network technologies, video applications become more and more popular. DiffServ (Differentiated Services) is a suitable architecture to ensure quality of service for simultaneously transmitted video and data streams. In this paper, we evaluate video streaming performance over DiffServ Domain, using myEvalvid extension in ns2. From a comprehensive evaluation, we find that: (1) Employing TSW2CM or other policies with more than one dropping priority is not necessary. (2) Scheduling mode influences the video transmission greatly, especially for parameter weight in WRR or WIRR mode and parameter “maximum consumed bandwidth” in PRI mode. (3) The influence of RED parameters is slight.
