| 摘 要： | 通过对丢包率进行卡尔曼过滤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友好拥塞控制机制。对该机制的TCP友好性、视频的回放质量进行了试验和结果分析。

| Abstract: | Based on the analysis of TCP-friendly congestion control mechanism, a TCP-friendly and RTCP feedbackbased congestion control mechanism was proposed. The ratio of dropped packet was analyzed by Kalman filter to forecast the status of network load. The sending rote was adjusted by setting up the buffer. The character of TCP-friendly and the quality of playback of this congestion control mechanism was tested and analyzed by network simulation. |

| Keywords: | large quantity real-time congestion control, TCP-friendly |
