基于控制论的ATM拥塞控制算法

ATM网络的多业务复用特性及其对QoS的承诺，使得其流量和拥塞控制变得非常复杂。控制论是分析和设计复杂系统的强有力工具，文章运用控制理论闭环反馈理论，设计了PI调节器，实现了基于PI调节器的ATM拥塞控制算法，实验及理论分析结果表明，该算法具有较强的稳定性与鲁棒性。

Congestion Control Algorithm Based on Cybernetics

A simplified ATM network structure is modeled and analyzed, and a controller is designed with the PI adjuster, which are often used in the classical control theory.And then, the modeling method of the congestion control of ABR service in ATM network is discussed. This paper It mainly analyzes the elements in the network and the factors, which influence the effect of the congestion control. Some problems and rules are identified, which must be considered during the processing of modeling. According to the conclusion of the discussion, a mathematic congestion model corresponding to a common network structure is developed, a control and optimized object is established for the future work.
