| 摘 要： | 本文针对PI控制器响应速度方面的不足，提出了一种自适应网络动态变化新的主动队列管理算法--API-V控制器。在PI控制器的基础上，根据瞬时队列长度，增加速度控制；根据实时测量链路的数据包丢失率，获得当前的负载信息，动态调整PI算法中的有关参数。理论分析和仿真表明，API-V控制器相对于PI控制器及其改进算法，不仅具有更快响应速度和收敛速度、更小的队列抖动，而且提高了缓冲区的利用率。

| Abstract: | An adaptive proportional integral-velocity(API-V) Controller for new active queue management scheme was proposed, which is well suited to dynamic network environments based on velocity control, in order to address the slow response of PI controller. Velocity controller was added based on PI controller when the length of queue is larger. The controller obtains present load information according to present measured dropping probability, then sets up the relevant parameters in PI scheme dynamically. Analysis and simulation results show that API-V controller can not only achieve faster convergence speed, faster response and smaller queue oscillation than PI controller and improved PI controller but also increase the buffer utilization. |
