IEEE1588 clock synchronization accuracy analysis

With the rapid development and application of distributed systems and Ethernet technology, higher requirements have been put forward for the clock synchronization of the global network. The IEEE1588 protocol is able to achieve high-precision clock synchronization, which meets the time accuracy requirements of real-time distributed systems. Therefore, this paper introduces the principle of the IEEE1588 clock synchronization technology and constructs a test environment to analyze the clock synchronization accuracy it can achieve from both theoretical calculation and experimental test. The results show that IEEE1588 clock synchronization can achieve sub-microsecond level time synchronization, with high-precision clock synchronization capability, and can be widely used in high real-time distributed systems.
