摘要
积极队列管理是IP网络拥塞控制的主要手段之一.本文从控制理论的角度描述带有积极队列管理的端到端的拥塞控制系统结构,介绍了网络系统受控对象的一种传递函数模型,综述了基于该模型的RED参数整定,以及P、PI、自适应控制等积极队列管理算法的设计和分析,指出受控网络模型精度、控制器的鲁棒性等进一步的研究方向.
Active queue management (AQM) is one of the main congestion control methods in IP network. In this paper we systematically analyze the architecture of the end-to-end congestion control schemes with AQM from the control-theoretic point of view. A transfer function of a simplified network's model is introduced. Based on the model, the configuration of RED and some other AQM algorithms are discussed. Finally we propose some future researches including the precision of network models and robustness of the control algorithms.
