Analysis of Smoothing Algorithm of Stored Video Transmission

网络边缘或终端系统的视频流平滑技术减少了进入网络的视频流量的突发性 ,可明显改善网络资源利用率 ,因此阐述了视频流量平滑技术的理论和模型 ,对比介绍了几种典型的视频流平滑算法 ,并提出一种改进的 PCRTT+算法。仿真表明 PCRTT+在保持原 PCRTT算法运算复杂度小的同时 ,能满足缓冲器限制 ,同时提高了平滑效率。

The video smoothing techniques bring a more smooth traffic to the core networks and improve network utilization with guaranteed QoS, which is very important and useful for network utility. This paper introduces the theory of video smoothing techniques and put forward an improved PCRTT+ algorithm after comparing some typical smoothing algorithm of video transmission. PCRTT+ keeps computation in a less complex state and meanwhile satisfies the buffer restriction, and also raise the smoothing efficiency.
