| 摘 要： | 针对早期随机检测(RED)算法的wq等参数设置对网络变化敏感的问题，提出一种去掉低通滤波器，引入freeze_time参数的改进算法，并在“大时滞负载变化”和“TCP加UDP混合流网络”这2种情景下进行仿真验证。实验结果表明，在大范围动态网络中，RED改进算法能获得更高的吞吐量和更低的网络时延，具有较好的队列控制性和健壮性。

| Abstract: | In dynamic networks Random Early Detection(RED) algorithm is sensitive to parameters, as wq etc.A Modified RED(MRED) algorithm is proposed, which discards low-pass filter and introduces a parameter freeze_time.This algorithm is simulated in two scenarios:"large delay and changing load","mixture flows of TCP and UDP".Experimental results show that in dynamic networks MRED algorithm achieves higher throughput and lower end-to-end delay, it can control the instantaneous queue better, and shows good robustness. |

| Keywords: | Modified RED(MRED) algorithm large delay load changing mixture flows |
