Abstract

This application discloses a clock synchronization method and apparatus, and a storage medium, which pertains to the field of communication technologies. The method includes: first receiving, by a network device, an announce packet from a first master clock node and an announce packet from a second master clock node, when an identifier of a first clock source node carried in the announce packet from the first master clock node is the same as an identifier of a second clock source node carried in the announce packet from the second master clock node, selecting a master clock node with a relatively small clock deviation, and then calibrating a clock of the network device based on time information of the master clock node. In this application, precision of clock synchronization performed by the network device is higher, and further, precision of a clock calibrated by the network device is higher.
