摘要： 提出了新的TCP速率调整算法。根据边缘路由器缓冲区中的输入数据报和输出数据报的变化,得到合理阻塞控制窗口,直接通过明确阻塞标记数据报返回到发送终端,从而改变了TCP发送速率。通过对仿真结果的分析,新算法可以明显地控制TCP的业务量,限制边缘路由器的队列的拥塞,大大降低数据报的丢失率,从而提高TCP的延迟性能和带宽分配的公平性。

Abstract: This paper presents a new TCP rate control scheme which is different from other schemes. The main ideal is to periodically get the ratio of input packets and output packets in the edged routers, and the rational congestion control window is obtained. The explicated congestion notification including calculated congestion control window transfers back to sender, the TCP sending rate is changed rapidly. The simulations show that the new scheme can efficiently control traffic to limit queue build-ups and buffer requirements at the network devices, resulting in significant improvements in delay, packets loss rates, fairness bandwidth and link utilization.
