摘要
ATM的拥塞控制是ATM网络业务管理的关键问题,目前应用成熟的控制理论方法来设计拥塞控制器的研究逐渐兴起.本文用动态矩阵控制中的内模控制方法研究ATM网络拥塞问题.在动态模型设计中,考虑了多瓶颈节点的情况,通过设置反馈滤波器尽量降低实际网络中不可控流对输出的影响,提出的一种拥塞控制算法,更加适合网络的实际情况,获得了较好的动态性能.仿真结果表明了该方法的有效性.
The congestion control for ATM is a key question in ATM networks＇ management, at present, the study of applying the developed controlling theory to devising congestion controller is rising gradually. In this article, the congestion for ATM networks is studied on the basis of dynamic matrix control theory. Considering the multi-bottlenecks, a algorithm is presented for the congestion control in the dynamic device, through setting a filter to the system, it can reduce the influence of the fluctuate in real network. It will fit the networks better, and have a good dynamic function. The effectiveness of proposed methods is demonstrated by simulation results.
