【Abstract】 The concepts of time-triggered Ethernet technology,development status, service category,and the transmission characteristics were introduced.The principles of synchronization control and communication table generation algorithm were analyzed.Based on these theories, the TTE end system’s configuration and its types of transmission services were described detailly.In an engineering application,the localized platform end system and switch communicated well with corresponding systems of TTech Company in TT service and BE service.It shows that the localized platform has good performance and the traditional Ethernet transits as far as possible.It also illustrates that TT has accurate and real time performance.With the software reality, the main implementation procedure and demonstration effect in this project are shown as well.更多还原
