基于区分服务的流媒体传输模型

流媒体在网络上的应用经常会受到数据包丢失或错误以及网络带宽资源不足的干扰，使得接收方播放质量受到严重影响。本文建立了一种适合流媒体传输的区分服务模型，该模型能够使高优先级数据流（实时流媒体数据流）占用更多的带宽。仿真结果表明：该策略能使流媒体数据流获得较高的吞吐量和较低的丢包率，有效提高流媒体传输的可靠性和实时性。

Media Streaming Transmission Model Based on Diffserv

Media streaming applications over networks are often disturbed by data packet loss and errors as well as the imuflaciency of network bandwidth, which degrades the video quality on the receiving side. In this paper, we establish a diffserv model suit for media streaming transmission, which enable high-priority data streams （such as media streaming data streams） to be assigned more bandwidth. The simulation results demonstrate that the proposed mechanism can obtain higher throughput and lower packet loss rate, and achieve reliability and real-time performance on the receiving side.
