【摘要】 主动队列管理算法是近年来网络拥塞控制研究的热点领域之一,但在已有的主动队列管理文献中,给出的仿真结果大多是在各种不同网络环境下得到的,因而不具有可比性。为了能够在系统地比较PI算法、REM算法、Q-SAPI算法和SAPI算法几种主动队列管理算法性能的优劣,本文在相同的网络环境下进行了大量的仿真实验。仿真结果表明,SAPI算法的性能明显优于其它三种算法。同时也说明,对网络拥塞控制这种强非线性、参数时变的系统,需要主动队列管理算法具有参数自适应性才能获得满意的性能。
【Abstract】 Active queue management (AQM) is an active research area of network congestion control.However,the simulation results given by AQM references were obtained in different network scenarios so that they did not have comparability.In this paper,to compare the performance of PI,REM,Q-SAPI and SAPI,a lot of simulations are run under same network scenarios.The simulation results show that the performance of SAPI is obviously superior to that of other three AQM algorithms.At the same time,the results show that an adaptive AQM algorithm is necessary for the nonlinear,parameter time-varying network congestion control systems to obtain satisfactory performance.
