Abstract
Disclosed is a time synchronization method and apparatus. The method includes: receiving a time synchronization message sent by an upstream device through a clock port; obtaining a message rate parameter in the time synchronization message; according to the message rate parameter, correcting a time synchronization message loss detection parameter of a slave clock port, wherein the time synchronization message loss detection parameter is used to detect whether the time synchronization message is lost; and according to a correction result, keeping clock synchronization with the upstream device.
Claims18
A time synchronization method, comprising:
- receiving, through a slave clock port, a time synchronization message sent by an upstream device;
- obtaining a message rate parameter in the time synchronization message;
- correcting a time synchronization message loss detection parameter, for detecting whether the time synchronization message is lost, of a slave clock port according to the message rate parameter;
- and
- keeping clock synchronization with the upstream device according to a correction result.
A time synchronization apparatus, comprising:
- an interface module, configured to receive, through a slave clock port, a time synchronization message sent by an upstream device;
- a message rate parameter extracting module, configured to obtain a message rate parameter in the time synchronization message;
- a message loss detection module, configured to correct a time synchronization message loss detection parameter, for detecting whether the time synchronization message is lost, of a slave clock port according to the message rate parameter;
- and
- a clock synchronization module, configured to keep clock synchronization with the upstream device according to a correction result.
