Abstract
Aspects of the disclosure provide a network device. The network device includes a first port coupled to a first device to communicate with the first device, and a clock wander compensation module. The first port recovers a first clock based on first signals received from the first device. The clock wander compensation module includes a global counter configured to count system clock cycles based on a system clock of the network device, and a first port counter configured to count first clock cycles based on the recovered first clock. Further, the first port transmits a first pause frame to the first device based on the global counter and the first port counter.
