Abstract

See full text

Provided are a time synchronization method allowing a fixed time delay and a bridge that is interposed between a master and a slave, according to the method. In the bridge, a predetermined time after the synchronization packet is set as an output time of the synchronization packet and the synchronization packet is output at the output time. Accordingly, it is possible to delay synchronization packets in the bridge for the same time, thereby increasing the time synchronization precision.
