Testing the Quality of Clock Synchronization

Although it is just easier to buy the equipment available to test the synchronism of two independent systems, we discuss here the measures of synchronicity – Accuracy of Time. The reader would thus be able to choose among the available products in market and appreciate them better (after having gone through the Synchronization basics and… Read More

Comparison - SyncE, NTP, GPS, IEEE-1588

We, now have enough information to compare various synchronization methods after we went through the clock synchronization basics and the Synchronous Ethernet (SyncE), IEEE-1588 technologies. In this section we would look at various factors through which we can have a comparison – SyncE, NTP, GPS, IEEE-1588 and evaluate these technologies: Network Load: Sync-E works at… Read More

1588 Software Design and Multi-core

From a high level, IEEE-1588 software design and multi-core design and implementations consist of time-stamping hardware, protocol parsing software and filtering and clock correcting algorithm. The prior article mainly dealt with how the time-stamps were exchanged between master and its various slaves while the next article would deal with the related algorithms. This section deals… Read More

IEEE-1588 v2 Clock Recovery

In continuation of time-synchronization article series, conceptually, IEEE-1588 synchronization is as simple as if you were asking the time from somebody and (s)he replying after looking at his/her watch. You would then correct your watch accordingly. This is simply: Time to be set = Time told + some delay But this simplicity just ends here.… Read More
