Since both video compressing rate and network bandwidth keep increasing continuously, more and more video applications emerged. Although DiffServ (Differentiated services) is a simple and effective architecture to ensure quality of service for simultaneously transmitted video and data streams, it is not suitable for multiple video streaming. In this paper we evaluate the performance of multiple video streaming using standard DiffServ architecture and two priority based enhanced schemes (named IP based scheme and CCP based scheme). Simulation results show that (1) IP based scheme outperforms CCP based scheme and standard DiffServ. (2) WRR and WIRR scheduling modes are suggested to be adopted. The higher the data rate of a video is, the larger the weight of that video should be set to. (3) RED parameters for different queues should be carefully set according to the available bandwidth for video streams, and the data rates and coding structures of different videos.
