基于延迟抖动的流媒体传输QoS机制

Research on Transmission QoS of Streaming Media Based on Delay Jitter

着眼于流媒体的传输服务质量问题,研究给定网络条件下流媒体的自适应传输策略,提出了一种基于延迟抖动的流媒体传输QoS(Quality of Service)方法。仿真实验表明该方法能够迅速判断网络状态,使流媒体的数据传输与网络当前状态及时吻合,能够获得较低丢包率的同时获得较大数据传输量,从而提高流媒体传输的QoS。

It focus on transmission QoS of streaming media and research on adaptive transmission strategy under existing network. A transmission method of streaming media based on the delay jitter is put forward in this article. The simulation shows that this method can quickly determine the network status, make the transmission of streaming data adapt to the current status of network in timely, obtain lower rate of packet loss while obtain larger throughput and therefore improve the transmission QoS of streaming media.
