DIFFERENTIAL CLOCK RECOVERY METHOD AND DEVICE

摘要

Disclosed are a differential clock recovery method and device. The method includes: a timing cycle is set for reference by all the network devices; when receiving a CBR service, a network device at the sending end counts the total information amount of the CBR service and sends the same to a network device at the receiving end; and the network device at the receiving end recovers the clock according to the total information amount of the CBR service and the timing cycle. By means of the technical solution provided in the present invention, the problem that it is difficult to communicate due to inconsistent clock frequency points of network devices in the existing differential clock recovery method is solved, further achieving the effects of neglecting the clock frequency points and simply and reliably recovering the clock.
