Abstract
Disclosed are a time synchronization method and system. The method comprises: an NEand the upstream nodes of the NEare classified into the first level, and the downstream nodes of the NEare classified into the second level, where the first level priority of the first level is higher than the second level priority of the second level; an NEconnected to the NEthrough a PTP synchronization link in the downstream node receives a first device priority of the NEand the first level priority from the NE; and after the NEreceives the second device priority of an NEand the second level priority sent by the NEin the downstream nodes which is connected to the NEthrough the 1PPS+TOD synchronization link, determines that a clock parameter of the NEis optimal, and synchronizes the local clock to the NE
