Title:
CLOCK PORT ATTRIBUTE RECOVERY METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/139692
Kind Code:
A1
Abstract:
The present application discloses a method for implementing clock port attribute recovery, a device, a system, and a storage medium, being applied to the field of clock technology. Said method comprises: according to the fact that a clock port on a network device has not received N clock messages of any one of three types of messages, synchronization message, follow-up message and delay response message, within a timeout time, the network device setting the value of the port attribute of the clock port to a first value, which indicates that message loss occurs at the clock port; and according to the determination that a recovery condition is satisfied, the network device setting the value of the port attribute of the clock port to a second value, which indicates that the state of the clock port is that no message loss occurs.
