摘要: 针对随机早期检测(random early detection,RED)主动队列管理机制的参数依赖问题,提出一种以网络流量优化理论中“价格”的变化为依据,自适应调节参数的RED改进算法。仿真实验结果表明,该算法明显提高了链路的利用率,降低了丢包率和平均队列长度。

Abstract: To alleviate the parameter dependence problem of random early detection (RED) algorithm, an improved method is proposed. The main idea is to adaptively adjust the parameter according to the changed “price” presented in the network traffic optimization theory. The simulation results show that the improved algorithm can improve link utilization, decrease packet loss rate and the average length of buffer.
