| 摘 要： | 大数据量实时视频流传输系统有广泛的应用前景。大数据量、高带宽要求的视频流传输中存在许多问题。网络的负载均衡、视频的回放质量都将严重影响整个网络的安全以及传输系统的应用。通过对丢包率进行卡尔曼过滤(Kalman Filter)分析预测网络负载状况、结合接收缓冲区大小设置来平滑发送速率,在分析TCP友好拥塞控制的基础上,提出了一种基于RTCP反馈的TCP友好(TCP-Friendly)对该机制的TCP友好性、视频的回放质量进行了实验和结果分析。

| Abstract: | There is broad application perspective of large quantity video stream transmitting system and many problems in transmitting the large quantity and high bandwidth video stream.Network overload equilibrium and the quality of video playback all affect the security of network and the application of video stream transmission system.On analyzing status of the network overload to forecast the ratio of dropped packet by Kalman Filter and smoothing the sending rate by setup the buffer,a TCP- Friendly and based RTCP feedback congestion control mechanism fitted large quantity video stream transmission is provided based on studying the TCP-Friendly congestion control.In the end,the character of TCP-Friendly and the quality of playback of this congestion control mechanism is tested and the result is analyzed by network simulation. |
