LexyBit.com Linux Software, Embedded Systems, Crypto Currency, Finance, and much much more … Crypto Currency  The main purpose of the currency is to aid exchange of goods. But, here we are talking of currency as an asset-class, like the limited-Gold, contrary to the infinite-fiat (like Rupee or Dollar). This is what the block-chain technology promises.… Read More

Comparison – SyncE, NTP, GPS, IEEE-1588

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 synchronization

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

Synchronization in Networks


(Continuing from the previous post: “Clock Synchronization in Telecommunication Networks“…) Like layers in a network, time synchronization consists of two basic layers: Phase synchronization; and Frequency Synchronization (Read more about Synchronous / Asynchronous / Isochronous / Plesiochronous) It is extremely easy to grasp this concept by considering the day-to-day questions: Why do you always make… Read More

Time Synchronization in Telecommunication Networks


Ques: How do we synchronize the clocks across nodes in a telecom network? Answer: Instead of relying on nodes “keeping” their own sense of time, the time is “distributed” across the network hierarchy. Two promising solutions: Synchronous Ethernet and IEEE 1588 are presented in this article as well as their “combination” to deal with the… Read More
