摘要: 文章在深入分析EPA网络周期数据传输原理的基础上,讨论了周期数据在EPA网络的端到端传输过程及在端点的处理过程中的通信延迟构成,并以一个典型的微网段构成的EPA网络为例,对EPA网络的周期数据通信延迟进行了定量计算,从而得出EPA网络所能达到的实时性指标,并指出了改善EPA网络实时性能的措施。Abstract: On the base of analyzing transmission principle of periodic data in EPA network deeply,the paper discussed communication delay composition of periodic data in end-to-end transmission process of EPA network and end treatment process.And it took a typical EPA network composed of micronet segments as an example to do quantitative calculation of communication delay of periodic data of EPA network, so as to get real-time indexes which EPA network could reach.It also pointed out measures to improve real-time performance of EPA network.
