Title:
TIME SYNCHRONIZATION METHOD AND APPARATUS UNDER MULTI-HOP NETWORK, AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/031912
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of network technology and security, and provides a time synchronization method and apparatus under a multi-hop network, an electronic device, a storage medium, and a computer program product. The method comprises: a child node acquiring a first message, the first message comprising time information of a root node of the child node sending the first message and time information of each parent node of the child node receiving and sending the first message; determining the time of receiving the first message as second time information; sending a second message to the parent nodes of the child node, so that the parent nodes send the second message to the root node of the child node; acquiring a third message; and determining a synchronization time of the child node according to the time information in the first message, the second time information, and time information in the third message. In embodiments of the present disclosure, the child node can acquire time information of each upstream node, and a calculation result is directly synchronized with a time source, so that a synchronization error after calculation is prevented from being transmitted to downstream nodes, and the precision of time synchronization among nodes in a network is improved.
