Abstract

See full text

A time synchronization method includes, a boundary device of a third-party network side receives a synchronization packet carrying a time synchronization offset and is delivered by a boundary device of an upstream network side on the basis that boundary devices in an entire network are all boundary clock (BC) devices, where the time synchronization offset is a time offset between a time domain of the upstream network and a time domain of the third-party network, and the boundary device of the third-party network side transparently transmits the synchronization packet carrying the time synchronization offset to a boundary device of a downstream network side such that the boundary device of the downstream network side performs time synchronization with the boundary device of the upstream network side according to the time synchronization offset. Thus time synchronization among multiple time domains in a network.
