[Abstract]:Aiming at a real-time network protocol, time triggered Ethernet (time triggered ethernet,TTE), which is used in the key field of security, the clock synchronization protocol of TTE is analyzed and studied. The clock synchronization flow and the protocol involve timing retention algorithm and centralized algorithm. Clock synchronization algorithm is studied and analyzed. The model of network switch and node computer is established, the simulation platform of time-triggered network communication is constructed, and the time triggered Ethernet clock synchronization protocol is simulated and analyzed, which verifies that the time synchronization algorithm can complete time synchronization. And the accuracy is within 95 ns.
