| 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 perf... |
