Abstract
A method for synchronizing clocks, including: receiving at least two clock signals, where the at least two clock signals are sent by a bidirectional clock tracking link respectively corresponding thereto; setting two or more clock signals coming from a same network element into a same clock source group; selecting one clock signal in a same clock source group as a currently tracked clock signal; and if the currently tracked clock signal belongs to the clock source group, respectively sending a standby clock signal carrying quality-level do not use information by using the bidirectional clock tracking link respectively corresponding to each of the clock signals in the clock source group. The present invention achieves the effect that in the scenario where there are two or more bidirectional clock tracking links between two network elements, a clock tracking loop will not be generated.
