Method and device for implementing automatic compensation for asymmetric delay of 1588 link

摘要

A method and device for implementing an automatic compensation for an asymmetric delay of a 1588 link. The method comprises: measuring by calculation a value of the asymmetric delay of an uplink/downlink of the 1588 link; when the value of the asymmetric delay exceeds a set synchronization offset range performing an asymmetric delay compensation; and if the value of the asymmetric delay does not exceed the set synchronization offset range continuing an ordinary 1588 time synchronization; thus implementing the automatic compensation for the asymmetric delay of the 1588 link. The solution allows for automatic correction of the asymmetric delay thus ensuring the quality of 1588 time synchronization.
