ABSTRACT:
A clock control system for a reference network device, the clock control system including a reference clock module, a receiver module, and a clock adjustment module. The reference clock module generates reference clock signals. The receiver module receives and determines reference receive times of Y frames based on the reference clock signals. One of X remote network devices generates the Y frames. The receiver module further receives X-1 timestamp frames from X-1 of the X remote network devices based on receipt of the Y frames at respective ones of the X-1 remote network devices. X and Y are integers greater than or equal to 1. At least one of X and Y is greater than 1. The clock adjustment module determines and transmits clock adjustment signals for the X-1 remote network devices based on the X-1 timestamp frames and the reference receive times of the Y frames.
