In my previous article, I discussed about the typical synchronization requirements in 5G xhaul network. To set the background, please peruse it at https://www.dhimanchowdhury.com/2021/08/11/the-critical-imperatives-of-time-synchronization-in-5g-networks/ .Traditionally, fronthaul is defined as the fiber-based connection in RAN infrastructure between the Baseband Unit (BBU) and Remote

 Time synchronization is critical to 5G infrastructure and fundamental conduit of the network. It begins with the very spectrum on which the fifth generation (5G) RAN (Radio Access Network) depends upon. The 5G Radio spectrum uses TDD (Time Division Duplex) as the preferred method of spectrum usage. In TDD, a single frequency is shared for uplink and downlink communications. Given the

As the fronthaul networks are upgraded to support higher bandwidth for LTE Advanced technologies and 5G, MNOs (Mobile Network Operators) are face with unparalleled challenges to comply with stringent requirements for the synchronization or sync plane across the network. We are witnessing paradigm shift in traditional telecom networks that rendering the transport networks in two

Tech giants are thronging to help fight against coronavirus joining the growing numbers of educational and research institute. It is an unprecedented effort in which “corporate america” and research institutes are extending helping hands to government for the war on coronavirus.  A consortium is formed in which IBM, Microsoft, Amazon and Google are now

Around the world countries are taking drastic measures to protect their citizens against a rare form of flu pandemic known as COVID-19 or (Corona Virus Disease 2019) [1]. While governments, researchers and health professionals working tirelessly to contain the pandemic and find cure against this rapidly spreading disease, you too can help by allocating your computer resources to towards

You heard it right, “Zero Trust”. Unlike human being who can innately identify stranger from friend and appropriately facilitate trust, network infrastructure is incapable of distinguishing friend from foe. It requires well planned initiatives, tools and mechanisms to enable anomaly detection capability in a network infrastructure. In traditional deployment, an innate trust is applied to

Today, cloud and virtualization are increasingly pushing the need to abolish hierarchical construct of network to a simpler and dynamic flat service-oriented infrastructure. And, it is for good reason: create non-blocking architecture, reduce cost and complexity and improve latency and manageability of the network. As network flattened, tiered notion of aggregation blends away to form two

There is an ominous rumbling in the internet about 768K day, some even termed it internet doomsday others called it “Y2K” of internet. The fear is justified given the experience of wide spread internet outage during 512K day when internet BGP table size exceeded 512,000 routes. The 512K day caused havoc and many routers simply exhausted of TCAM (Ternary content-addressable memory) size and

Today, most businesses don’t need any convincing argument about how digital transformation can enhance their agility. The pressing question is how to onboard more and more consumers and how to provide improve service through differentiated offerings. Given the pivotal role of networks in this era of cloud-powered enterprise, low-cost-per bit is central to creating digital transformation.

It is insanely fast, even a maverick will agree! And, it is equally fattish than the all known preceding transports technologies given that a 1 RU switch can now pack a whopping 12.8 Tbps bandwidth: get the picture?

Gothenburg is a port city nestled within the unique Kattegat (a sea area considered neither North Sea nor the Baltic Sea, a contradiction in itself) nearly 290 miles northwest of Stockholm, capital of Sweden. The days are gloomy here specifically in the fall season and in the winter, fortunate to have a glance of sun if you are lucky yet the city has much to offer. Gothenburg’s panoramic

One of the fascinating aspects in my job is understanding how some of world’s largest networks will deploy Open networking platforms. It is this continuous learning that keeps me passionate about what I do.  When I first use “open networking” term, people wondered what it may entails.  Some thought of it is all about using “open source” software and the other thought of it as another

Today, innovation is viewed as the main determinant of organizational success and competitiveness. There is no argument about the necessity of innovation in each organization but question is how to foster it. I have earlier published few articles including a behavioral connotation for organizations to foster innovation behavior at individual and group level. You can download one of the
