| 摘 要： | 基于主动队列管理(AQM)控制理论模型，针对PI(proportional integral)控制器响应速度方面的不足，在PI控制器基础上增加了归一化输入速率控制，提出了一种适应网络环境动态变化的AQM算法——P〖JP9〗I-〖JP〗R(proportional integral rate)控制器. 理论分析 和仿真实验证明，P〖JP9〗I-〖JP〗R控制器在保证队长稳定和链路利用率的同时实现了对 网络状态变化的快速响应，也可以提高缓冲区利用率.

| Abstract: | A proportional-integral-rate (PI-R) controller for active queue management (AQM) scheme based on the linearized AQM model was proposed. PI-R controller is well suited to dynamic network environments where traffics change frequently. In order to address the slow response of PI controller, a normalized input rate control PI-R controller was used to speed up the responsive time under varying network conditions. Analysis and simulation results show that under varying network conditions PI-R controller will have a fast response and improve the buffer utilization, and have a good perform in stability and link utilization. |
