In the experiment, we deal with four packet scheduling algorithms: First-In First- Out, Priority Queueing, Class-Based Queueing and Weighted Fair Queneing. We assess the synchronization quality of both Intra-stream and inter-stream with and without media synchro- Nization control. The paper clarifies the features of each algo- Rithm from a media synchronization point of view. A comparison Of the experimental results shows that Weighted Fair Queneing Is the most efficient packet scheduling algorithm for continuous Media among the four. 收起
