Title:
METHOD, APPARATUS, AND DEVICE FOR DETERMINING CLOCK TIME OF TIME SYNCHRONIZATION PACKET
Document Type and Number:
WIPO Patent Application WO/2018/041108
Kind Code:
A1
Abstract:
Disclosed are a method, apparatus, and device for determining clock time of a time synchronization packet. The method comprises: adding multiple ingress timestamps for a received time synchronization packet, each ingress timestamp corresponding to one timing system; determining a target ingress timestamp in the multiple ingress timestamps according to a packet type of the time synchronization packet, and determining an egress timestamp by using a timing system corresponding to the target ingress timestamp; and determining clock time of the time synchronization packet according to the target ingress timestamp and the egress timestamp.
