Method, system, computer device and storage medium for clock synchronization

Abstract

The invention relates to a clock synchronization method and system, computer equipment and a storage medium. Port initialization is initiated through network nodes which are adjacently connected. Therefore, the transmission delay and the relative clock deviation between adjacent network nodes are determined; the synchronization process can be completed in the data link layer; therefore, any network node can initiate a synchronous message; the adjacent receiving network nodes finish the synchronization of the local clock according to the synchronous message, the transmission delay and the relative clock deviation; forwarding and modifying the message to the next network node under the condition of considering the data forwarding delay; therefore, one path of the message is transmitted so asto realize synchronization of a system in which a plurality of network nodes are interconnected, and synchronization is carried out on a data link layer, so that the problem that relatively large errors are generated due to the fact that data transmission on a physical medium is easily influenced by unreliable factors is solved, and the synchronization precision is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a clock synchronization method, system, computer equipment and storage medium. Background technique [0002] With the development of communication technology, the speed of data transmission is getting faster and faster, and the requirements for clock synchronization are getting higher and higher. The traditional IEEE1588 defines the synchronization between two devices, and the synchronization process is generally completed step by step under the leadership of the master station (with the intervention of the CPU in the master station). [0003] However, with the development of industrial Ethernet, the equipment system organically interconnects multiple network industrial modules with specific functions through Ethernet, and because of the particularity of industrial applications, communication is required to be fast, real-time, synchronous, and reliable. , Th...

Problems solved by technology

[0003] However, with the development of industrial Ethernet, the equipment system organically interconnects multiple network industrial modules with specific functions through Ethernet, and because of the particularity of industrial applications, communication is required to be fast, real-time, synchronous, and reliable. , therefore, the traditional IEEE1588 synchronization method is not suitable for a system where multiple network industrial modules are interconnected
