【摘要】 提出一种新的AQM算法——基于平均负载的阈值控制算法TLED,并研究在低延时状况下的性能情况。使用指数加权平均(EWMA)方法计算网络的平均负载强度,根据平均负载对数据包进行随机丢弃,通过一种阈值控制算法,将缓存区队列长度与负载状况有机结合起来,取得了吞吐量-队列延时的良好折中,并有效改善了原有的基于负载的控制算法对网络流量变化的自适应性。更多还原

【Abstract】 A new active queue management algorithm(AQM)called TLED is presented,based on average traffic load and threshold control. TLED uses average traffic load and queue length to denote the congestion level in the network, and calculates the drop- rate probability of packet. Simulations used NS- 2 to compare the performance with RED and LED. The result shows that TLED have better throughput- delay performance and better adaptability than RED and LED.更多还原
