ATM网络的自适应预测速率控制及其仿真研究

Adaptive Predictive Rate Control and Simulation Study in ATM Networks

异步传输模式(ATM)网络中随机接入用户数的动态变化、传输延迟的时变特征等不确定因素,使网络难于管理和控制,而且网络性能也会下降,甚至出现不稳定的振荡。本文利用自适应预测控制方法,设计了稳定的、公平的速率控制算法。该方法可以分布实现,易于扩展。仿真研究表明了本文方法的有效性。

Due to time-variant number of the users and time-varying round trip delay, severe uncertainties exist in ATM network, which cause great difficulty in managing and controlling of the networks and decrease the networks performance, or even make the system oscillation. A stable and fair rate control algorithm is presented based on adaptive predictive control. The method may be realized in every switch, which is easy to expand to large-scale networks. The effectiveness of the proposed methods is demonstrated by the simulation study.
