But till now , the stability of system , especially the oscillations of buffer occupancy have not been the focus of research in congestion control 但目前在拥塞控制方面的研究对于网络节点的缓冲占有量的抖动性即系统稳定性考虑不多。
With regard to the flow regulation of the best - effort traffic , the controllable traffic in high speed computer communication networks , the present paper proposes a novel control theoretic approach that designs a proportional - integrative ( pi ) controller based on multi - rate sampling for congestion controlling . based on the traffic model of a single node and on system stability criterion , it is shown that this pi controller can regulate the source rate on the basis of the knowledge of buffer occupancy of the destination node in such a manner that the congestion - controlled network is asymptotically stable without oscillation in terms of the buffer occupancy of the destionation node ; and the steady value of queue length is consistent with the specified threshold value 本文从控制理论的角度出发,针对计算机高速互联网中最大服务交通流即能控交通流的调节问题提出了一种基于多速率采样的具有比例积分( pi )控制器结构的拥塞控制理论和方法,在单个节点的交通流的模型基础上,运用控制理论中的系统稳定性分析方法,讨论如何利用信终端节点缓冲占有量的比例加积分的反馈形式来调节信源节点的能控交通流的输入速率,从而使被控网络节点的缓冲占有量趋于稳定;同时使被控网络节点的稳定队列长度逼近指定的门限值。
