| 摘 要： | 提出了一种新的拥塞控制源算法FAV(Forecast and Verify)，这是一种在接收方测量分组到达的延迟来预测网络中是否将出现拥塞的算法，并结合ECN来验证预测的准确性。通过和TCP Reno、TCP Vegas算法进行比较实验，表明FAV算法能够有效地减小丢失率和链路延迟，同时保持较高的链路利用率，从而使网络中的拥塞得到较好控制。

| Abstract: | A novel congestion control source algorithm FAV(Forecast and Verify) is presented. It measures packets delay to forecast whether there will be congested in network, and uses ECN to verify whether the forecast is precise or not. Lots of experiments are performed by ns2 to compare FAV with TCP Reno and TCP Vegas. The results imply that FAV algorithm can decrease loss rate and link delay efficiently, keep link utilization high, and control the congestion better than other source algorithms. |
