IMPLEMENTATION METHOD AND DEVICE FOR AUTOMATICALLY DETECTING ASYMMETRY TIME DELAY OF 1588 LINK

摘要

An implementation method and device for automatically detecting the asymmetry time delay of a 1588 link. The implementation method includes: operating a 1588 time synchronization protocol and calculating a time deviation value; amending the time of a slave clock according to the time deviation value, recording a time stamp of 1588 time synchronization, and calculating a time synchronization deviation value according to the time stamp of time synchronization; judging whether the time synchronization deviation value is greater than a pre-configured time synchronization deviation threshold; and if it is yes, then raising a 1588 link asymmetry time delay alarm, realizing the automatic detection of the asymmetry time delay of the 1588 link. The above solution can automatically detect the uplink and downlink time delay asymmetry of 1588 time synchronization by detecting the deviation amended time synchronization deviation value and comparing same with a pre-configured time synchronization deviation threshold, solving the problems that the detection is manually performed by means of specific testing instruments, and when the link is changed, re-detection is required.
