Title:
TIME SYNCHRONIZATION METHOD AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/098409
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a time synchronization method and device, and a storage medium. The method comprises: searching, at a SERDES parallel interface, for a synchronized block matching a preset code pattern in a data stream; determining the position of the bit of the synchronized block in the SERDES parallel interface as a first position; determining a time point when the synchronized block passes through the SERDES parallel interface as a first time point; searching, at PHY layer and MAC layer interfaces, for the synchronized block and a PTP packet in the data stream, and determining a distance between the synchronized block and the PTP packet; and determining a second time point according to the first position, the first time point, and the distance, the second time point being the time point when the PTP packet passes through the SERDES parallel interface.
