| 摘 要： | 分析TCP友好的拥塞控制机制.通过分析实时视频流传输过程中丢包事件的发生率来预测网络负载状况,并根据网络负载动态调整接收缓冲区大小.提出一种基于RTCP反馈的TCP友好(TCP-Friendly)拥塞控制方法,运用NS-2对该控制方法的TCP友好性、视频的回放质量进行试验和结果分析.

| Abstract: | The TCP-friendly congestion control mechanism was analyzed.The network loading condition was to be predicted by analyzing the occurrence ratio of packet drop-out during real-time video-stream transmission and dynamically adjusting the size of receiving buffer according to network loading.A method for TCP-friendly congestion control was presented on the basis of RTCP feedback.This control mechanism was tested and analyzed by using NS-2,also. |
