早期确定性拥塞指示算法

Early Explicit Congestion Notification Algorithm

分析了算法在拥塞指示信息传输上的不足,提出了一种早期确定性拥塞指示算法,使得拥塞指示能尽可能快地到达源,以REDTCP有效地响应路由器的早期拥塞。使用改进的进行了仿真实验,实验结果表明该算法在保证网络吞吐率的基础上,能更有效地降低路由器NS中的丢包率,提高网络的利用率。

This paper analyses the insufficiency of the transmitting of RED congestion notification and presents an early explicit congestion notification algorithm. The new algorithm ensures that the congestion notification can reach the TCP source as quickly as it can, in answer to the early congestion of routers. Some experiments are given in the paper using modified NS simulator. The experiments show that the algorithm is better than RED in reducing the packet loss rate besides guaranteeing the routers' throughput. ;;;
