摘要:
主动队列管理算法(AQM)是近年来网络拥塞控制的研究热点之一,已经提出了许多的主动队列管理算法,例如:RED,ARED,SRED,PI,REM等。文中设计一种基于控制理论的可变结构的主动队列管理。通过分析控制机制对于非线性的TCP/AQM模式的鲁棒性和性能,展示了在不确定的RTT(round-triptime)和活跃的TCP连接个数的情况下,有很好的性能和鲁棒性,这正是主动队列管理最重要的理念。运用网络仿真软件Ns对设计进行仿真验证,从不同的角度对其性能与现有队列管理算法进行比较。仿真结果显示,从稳定性和鲁棒性等角度,可变结构控制算法显著胜过现有的AQM算法
Abstract:
Active queue management algorithm (AQM) is a research area in network congestion control. There are many active queue management algorithms such as RED, ARED, SRED, PI ,REM have been proposed. In this paper, design an active queue management algorithm of variable structure based on control theory. By analyzing the robustness and performance of control scheme for the nonlinear TCP/AQM model ,show that the proposed design has good performance and robustness with respect to the uncertainties of the round-trip time and the number of active TCP sessions, which are central to the notion of AQM. NS simulations are provided to validate the design and compare its performance to other peer schemes' in different scenarios. Simulation shows that it takes the stability and robusmess indices into consideration, proposed design outperforms the other AQM schemes
