摘要： 采用仿真分析的方法，系统地研究了当前提出的用于Internet路由器缓冲管理的一系列主动队列管理(AQM)算法的性能。根据AQM的设计原理，将当前的AQM算法划分为3类：基于队列长度，基于网络负载和同时基于队列长度和网络负载的AQM算法。仿真研究和分析表明，现有的AQM算法不能适应网络流量的动态变化。

Abstract: Based on simulation analytical method, this paper systematically investigates the performance of series of recent AQM (active queue management) schemes designed for buffer management at routers in the Internet. According to their design principles, AQM schemes are classified into three categories: AQM based on queue length, network load, and a combination of them. Simulation investigation and analysis illustrate that existing AQM schemes are not adaptive to dynamic network traffic.
