Abstract
Clock synchronization is mostly needed in the distributed real-time system. Currently, the most popular Network Time Protocol (NTP) algorithm cannot meet the needs well due to its low accuracy (about 10 milliseconds) and high cost. Thus, an improved high-accuracy clock synchronization method is proposed in this paper to overcome errors and offsets. With this method, the error of clocks among computer nodes in distributed real-time system can be less than 2 milliseconds and high availability can be achieved. The method has been applied in national key engineering project.
