Time synchronization using dynamic thresholds

摘要

Methods and apparatus for time synchronization using dynamic thresholds. A method for synchronizing network elements includes receiving at a network element a time synchronization message sent from a master clock element. The network element includes an internal clock to be synchronized with a master clock of the master clock element. The method includes calculating a latency of the time synchronization message. The method includes estimating an adjustment that may be made to the internal clock in response to the time synchronization message. The method includes determining whether the latency calculated is less than the adjustment estimated. The method includes adjusting the internal clock when the latency calculated is less than the adjustment estimated.
