Document Type and Number:
WIPO Patent Application WO/2024/011410
Kind Code:
A1
Abstract:
A method and a network device are disclosed for precision time protocol (PTP) clock synchronization. According to an embodiment, the network device determines, for a plurality of candidate PTP clock sources, noise metrics reflecting variation degrees of propagation delays on paths between the plurality of candidate PTP clock sources and the network device. The network device determines, from the plurality of candidate PTP clock sources, a target PTP clock source for clock synchronization, based on at least part of the noise metrics.
