Based on the idea of time-triggered, global unified high precision time synchronization is the foundation of network deterministic communication. In the process of time synchronization, clock synchronization algorithm, transmission delay, clock drift and so on will affect the accuracy of clock synchronization. It is a great technical challenge to realize high precision and reliable clock synchronization. This paper collates and analyses the relevant literature, first introduces the time-triggered Ethernet, then analyses the time synchronization protocol that can be used for high-precision clock synchronization, reviews the development status of time synchronization technology and makes an overall analysis. Finally summarizes the clock synchronization difficulty and prospects the development trend of the time synchronization technology.
