Method and Apparatus for Selecting Clock Source - A simplified explanation of the abstract

This abstract first appeared for US patent application 18336891 titled 'Method and Apparatus for Selecting Clock Source

Simplified Explanation

The patent application describes a method for selecting a clock source in a network device.

  • The method involves obtaining synchronization offset data between two network devices through a specific port.
  • The network device determines whether to refer to clock information received by that port during clock source selection, based on the synchronization offset data.
  • This method helps in selecting the most accurate clock source for synchronization in a network device.


Original Abstract Submitted

A method for selecting a clock source includes a first network device that obtains synchronization offset data between the first network device and a second network device through a first port in a clock synchronization failed state. The first network device determines, based on the synchronization offset data, whether to refer to, during clock source selection, clock information received by the first port.
