Clock synchronization method and apparatus, and storage medium

A clock synchronization apparatus, comprising:

• a memory, comprising instructions;
• a processor coupled to the memory, when the instructions executed by the processor, cause the apparatus to:
• receive a first announce packet from a first master clock node and a second announce packet from a second master clock node, wherein the first announce packet carries a first identifier of a first clock source node and a first maximum clock deviation accumulated value, the second announce packet carries a second identifier of a second clock source node and a second maximum clock deviation accumulated value;
• select, from the first master clock node and the second master clock node based on the first maximum clock deviation accumulated value and the second maximum clock deviation accumulated value, a master clock node for clock synchronization when the first identifier is the same as the second identifier;
• and
• calibrate a clock of the clock synchronization apparatus based on time information of the master clock node.

A non-transitory computer-readable storage medium having program instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:

• receiving a first announce packet from a first master clock node and a second announce packet from a second master clock node, wherein the first announce packet carries a first identifier of a first clock source node and a first maximum clock deviation accumulated value, the second announce packet carries a second identifier of a second clock source node and a second maximum clock deviation accumulated value;
• selecting, from the first master clock node and the second master clock node based on the first maximum clock deviation accumulated value and the second maximum clock deviation accumulated value, a master clock node for clock synchronization when the first identifier is the same as the second identifier;
• and
• calibrating, by a network device, a clock of the network device based on time information of the selected master clock node.
