Title:
METHOD AND NETWORK DEVICE FOR PTP CLOCK SYNCHRONIZATION
Document Type and Number:
WIPO Patent Application WO/2023/236048
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 whether the network device is in one of a first state where a reception of an announce message from a PTP clock source is interrupted due to a local change at the network device, and a second state where the PTP clock source is restored after a predetermined restoration time, or the reception of the announce message from the PTP clock source is recovered after the local change. When determining that the network device is in one of the first state and the second state, the network device uses the PTP clock source as a candidate PTP master, without waiting for the predetermined restoration time.
