  • Externally connected time port changeover method and device
    Patent number: 9325442
    Abstract: Disclosed are externally connected time port changeover method and device. The method includes: a node serving as a GM node transmitting time information via a first externally connected time port of the node; if the first externally connected time port fails, the node updating current node priority and GM node priority of the node as preset node priority which is node priority configured for the node when the node is activated; and the node judging whether a second externally connected time port of the node is up and the priority of the second externally connected time port is higher than the current GM node priority, if so, activating the second externally connected time port to transmit the time information. The problem that when the currently selected time access port has failed, changeover among ports cannot be completed in time is solved, thus improving the stability of the time synchronization network.
