  • Methods and devices for determining an availability of a synchronization source
    Patent number: 11223436
    Abstract: The present disclosure relates to a method for determining an availability of a synchronization source in a communication system. The method comprises: detecting a stability of the synchronization source when the synchronization source recovers from a failure; and determining the availability of a synchronization source based on the detected stability of the synchronization source. The present disclosure also relates to network devices and a computer readable medium for performing said method.
    Type: Grant

  • Method and apparatus for selecting path from paths between label edge routers
    Patent number: 9843511
    Abstract: The embodiments disclose a method and apparatus of selecting a path for transmission from paths between a first LER and a second LER in the MPLS network. The method may comprise: obtaining state information of the paths between the first LER and the second LER, the state information may indicate that a path is in up state or down state; obtaining stability information of at least one of the paths between the first LER and the second LER, the stability information may indicate that a path is stable or unstable; and selecting a path for transmission based on the state information and the stability information.
