摘　　要：如何对网络流量实施有效管理和控制是网络性能评价、网络协议设计和网络规划等考虑的关键因素之一。在对普通ILAN(工业局域网)底端现场总线分析的基础上,提出了一种流量计算的数学模型,据此模型,提出了一个基于PID方法的流量控制机制。实验仿真证明该PID机制具有良好的瞬态和稳态性能,鲁棒性好,网络资源利用率高。最后在工业局域网实际分析的基础上提出了一种改进型的流量控制机制。It's one of the key factors to consider how to manage and control the traffic of network effectively for network performance picture, network protocol design and network planning etc.In this paper a mathematical model with parameters of the flow is raised on the analysis of the industrial LAN.At the same time,a PID flow controller is also designed.The simulation results demonstrate the PID controller has good transient and steady state performance,good robustness and the network resource is on utilization rate.Finally an improved strategies of the flow controller is put up on the analysis of the industrial LAN.
