Abstract
The present disclosure relates to a clock distribution method and apparatus in a network. The method performed at a first clock distribution apparatus comprises: determining (S101) whether the first clock distribution apparatus is in a lock state; and transmitting (S102), to a second clock distribution apparatus, a first announce message when the clock distribution apparatus is not in the lock state; wherein the first announce message is generated based on a default configuration about a local clock state of the first clock distribution apparatus. According to embodiments of the present disclosure, the clock distribution apparatus may generate first announce messages based on a local clock state of the clock distribution apparatus. Thus, a downstream apparatus which receives the first announce messages may avoid selecting an unstable/unlocked clock distribution apparatus as the best master, based on the local clock state of the clock distribution apparatus.
