摘要 主动队列管理机制(AQM)是为了改进传统的端到端拥塞控制而提出的。现有AQM算法的设计在很大程度上依赖于直觉,没有全面、系统地运用理论工具,而算法的参数配置以及算法的稳定性分析需要借助于适当的理论。随机指数标记算法REM、比例积分控制器PI都在这方面作了探索性的研究。本文通过对REM算法的性能分析得到其性能与PI非常相似,进而通过控制论的分析指出二者具有相似的控制模型。最后,文章认为拥塞控制是一个比较典型的控制问题,控制论是解决问题的有力工具,并指出了今后的研究方向。 The mechanism of active queue management (AQM) is proposed to improve the traditional end-to-end congestion control in the Internet. But most AQM algorithms are designed intuitively, and appropriate theoretical analysis is needeck Some AQM algorithms, such as REM and PI, explore this aspect. The performance of REM is verified and compared with that of PI using NS simulations. The results show that REM and PI have similar properties. This paper explains this by control theory and provide further directions.
