摘要
以工业控制过程为背景 ,详细分析以太网端到端的通信延迟 ,给出排队延迟的期望表达式 ,发送延迟和传输延迟的计算方法 ;通过仿真 ,分析网络节点数目、帧的长度和通信速率对以太网实时能力的影响 。
Based on industrial control process,this paper detailedly analyzes end-to end delay of ethernet,and presents the expectation expression of queue delay and calculation procedure of send delay and transmission delay.By simulation,this paper also analyzes influence of three parameters on real-time capacity of ethernet,and puts forward improving methods on real-time capacity of ethernet in industrial application.These parameters are the number of nodes,the length of frames and communication rate.
