Blockchain technology applications

We are seeing a lot of innovation in the Blockchain technology applications and the use of distributed ledger. While each crypto and ICO launch is bringing in investments to the tune of millions of dollars, only a few of them can be called a real innovation. Have a look at these applications and services and… Read More

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

Exploring the Stock Market (Morality and Guilt-trip)

Stock Market Speculation

I recently started exploring the stock-market. I have been out of my college for more than 15 years, I am an Engineer, and I have worked really hard in various multi-nationals, contributed directly to product-based companies, creating new solutions, fixing things that were not behaving functionally correct, performance tuning others, proposing ideas for improvement, small… Read More

What is Plesiochronous

Phase difference

In this short article and your next 2 minutes, you are going to learn “What is Plesiochronous” and (be careful – once you know it you cannot un-know it), you can brag about this concept (and this seemingly-complicated word) to your friends (and foes). So, what is it? What does Plesiochronous really mean and what… Read More

Measures of synchronicity – Accuracy of Time

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

Synchronous Ethernet (SyncE)

SyncE ESMC Packet Format

In simple terms, Synchronous Ethernet extends the use of a PLL (Phase locked loop) clock to transmit data. At a very crude level, this, and only this, is the whole conceptual working of Synchronous Ethernet. At the physical layer, two Ethernet peer nodes are already synchronized through a PLL for the RX (receiving) end. A PLL… Read More

Synchronization in Networks

4 Comments

(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
