| 摘 要： | 针对Internet网络这种典型的延迟系统,基于模型预测控制理论,提出了一种新的主动队列管理算法——MPAQM算法。首先考虑时滞系统的因果性定义预测输出,根据预测模型和状态估计器,预测瓶颈链路队列的未来动态特性;然后将拥塞控制的控制要求转化为优化目标函数,求解优化问题得到丢包率。在单瓶颈和多瓶颈网络拓扑中进行仿真验证,结果显示MPAQM算法能快速平稳地收敛于队列长度的期望值,丢包率小且具有较好的稳定性和鲁棒性。

| Abstract: | Based on the theory of model predictive control,a novel Active Queue Management(AQM) algorithm is proposed for typical Internet systems with large delay,called MPAQM.First,the predicted output is defined by considering the causality of time-delay system.Then,according to the predictive model and state estimator,the future dynamic queue length in data buffer is predicted.Finally,the control requirement of congestion is converted to optimal control objective function,and drop probability is obtained by solvin... |
