摘要

本文提出了一种比例差分(PD)控制算法，作为TCP/IP拥塞控制的一种新的主动队列管理(AQM)方案。从控制理论的角度来看，TCP拥塞控制系统可以看作是一个反馈调节系统。本文提出了一种鲁棒AQM——pd -控制器。详细介绍了pd -控制器的设计原理。通过仿真对其性能进行了广泛的评价。结果表明，pd -控制器AQM对流量负载波动、UDP和HTTP干扰具有稳定的鲁棒性。并论证了其相对于其他AQMs的优越性。

PD-controller: a new active queue management scheme

This paper describes a proportional-differential (PD) control algorithm as a new active queue management (AQM) scheme for TCP/IP congestion control. From the viewpoint of the control theory, TCP congestion control system can be regarded as a feedback regulating system. In this paper, a robust AQM called PD-controller is proposed. The design principles of PD-controller are presented in details. Its performance is extensively evaluated by simulations. The results demonstrate that the PD-controller AQM is stable and robust against traffic load fluctuations, UDP and HTTP disturbances. Its superiority over other AQMs is also demonstrated.
