Abstract :
This paper studies effect of packet scheduling algorithms at routers on media synchronization quality in live audio and video transmission by experiment. In the experiment, we deal with four packet scheduling algorithms: first-in first-out, priority queueing, class-based queueing and weighted fair queueing. We assess the synchronization quality of both intra-stream and inter-stream with and without media synchronization control. The paper clarifies the features of each algorithm from a media synchronization point of view. A comparison of the experimental results shows that weighted fair queueing is the most efficient packet scheduling algorithm for continuous media among the four
