| 摘 要： | 通过采用一种基于Lyapunov泛函的多变量时滞系统分析技术对网络拥塞控制问题进行了研究,得到了系统以衰减度!指数稳定的鲁棒镇定条件,在此基础上提出了AQM网络拥塞鲁棒控制算法,所得结果不但可用于小时延网络(如LAN),同时也适用于大时延网络(如WAN、Internet),仿真实验表明采用该技术设计的网络拥塞控制算法具有良好的鲁棒性及控制性能。

| Abstract: | In terms of a kind of analysis technique to systems with multivariable delays based on Lyapunov functional,the congestion control is considered and the robust stabilized condition is derived so as to the system exponentially stable with attenuation rate λ.On the basis of these results,the robust AQM congestion control algorithm is obtained.The algorithm can be used not only in small Round Trip Time(RTT) system(e.g.LAN),but also in large RTT system(e.g. WAN and Internet).The simulation experimental results illustrate good robustness and controlled network performance of the congestion control algorithm designed by proposed method. |
