Title:
CLOCK SYNCHRONIZATION METHOD AND APPARATUS AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/135279
Kind Code:
A1
Abstract:
Disclosed are a clock synchronization method and apparatus, and a storage medium, wherein same belong to the technical field of communications. The method comprises: a network device firstly receiving an Announce message from a first master clock node and an Announce message from a second master clock node; when an identifier of a first clock source node carried in the Announce message of the first master clock node is the same as an identifier of a second clock source node carried in the Announce message of the second master clock node, selecting, from the first master clock node and the second master clock node, the master clock node bringing a smaller clock deviation; and then calibrating a clock of the network device according to time information of the master clock node. According to the present application, the master clock node with a smaller clock deviation is selected as a master clock node for the network device to perform clock synchronization, so that the network device is more accurate in clock synchronization, and thus, the accuracy of the clock is higher after same is calibrated by the network device.
