摘　　要：针对随机及早检测(RED)中存在的不稳定现象,提出了一种新颖的AQM算法LRC-RED,该模式具有快的响应速度、良好的鲁棒性以及高的链路利用率.LRC-RED是在RED,LossRadio,VRC,TCP/AQM等基础上提出的,它检查最近包的丢失率以及当前拥塞链路总速率,然后动态调整包的丢失概率以提高服务性能.为了验证算法的有效性,设计了一个有效的实验来检验.实验表明,该算法是可行的.Aimed at the unstable behaviors in random early detection（RED）, a AQM scheme with tast response time, good robustness and high link utilization was proposed. On the basis of RED, loss radio, VRC and TCP/AQM, the algorithm called LRC-RED was put forward. It measured the loss ratio of the latest packet and the current total rate of congested link. In accordance with the measurement, the probability of packet drop was dynamically adjusted to achieve high service performance. An experiment was designed to verify the efficiency of the algorithm. The result proved the feasibility of the algorithm.
