SD-WAN buyers guide: Key questions to ask vendors (and yourself)

Prior to the pandemic, SD-WAN was primarily a niche technology pitched to enterprises as a way to cut costs and improve WAN flexibility by allowing traffic to burst directly from the branch office to the Internet, rather than backhauling it over expensive MPLS links to a central site.

Another Portent of the Decline and Fall of the Telco

The Swedish carrier group Telia has recently announced the sale of its international wholesale business to Polhelm Infra, an infrastructure investment manager jointly owned by a number of Swedish pension funds. Why would a telco operator sell off what was a core part of its operation to a pension fund?

Whatever it is, you need more (RFC1925 rule 9)

There is never enough. Whatever you name in the world of networking, there is simply not enough. There are not enough ports. There is not enough speed. There is not enough bandwidth. Many times, the problem of “not enough” manifests itself as “too much”—there is too much buffering and there are too many packets being dropped. Not so long ago, the Internet community decided there were not enough IP addresses and decided to expand the address space from 32 bits in IPv4 to 128 bits in IPv6. The IPv6 address space is almost unimaginably huge—2 to the 128th power is about 340 trillion, trillion, trillion addresses. That is enough to provide addresses to stacks of 10 billion computers blanketing the entire Earth. Even a single subnet of this space is enough to provide addresses for a full data center where hundreds of virtual machines are being created every minute; each /64 (the default allocation size for an IPv6 address) contains 4 billion IPv4 address spaces.

But… what if the current IPv6 address space simply is not enough? Engineers working in the IETF have created two different solutions over the years for just this eventuality. In 1994 RFC1606 provided a Continue reading

Bash #1. Automating Troubleshooting (Cumulus) Linux Networking

Hello my friend,

Very often at our zero-to-hero network automation training we are asked, what is the benefit of Bash? Why do we need to know Bash, if everyone is talking about Bash? The question is absolutely legitimate. One of the interesting and also legitimate answers I’ve just figured the last week.

Do you finally write about network automation?

Everything in your network and IT operational processes can be automated. It is just matter of the resources (time, money, efforts) you spent on that against the gain you are obtaining. Basically, that is something what financial guys and girls call ROI (Return On Investments). The bigger the outcome and the lower the effort, the better the overall automation solution.

In our automation trainings we explain various use cases and success (and failure) strategies, how to build the (network) automation systems and tools, to make sure your gain is maximum. Our instructors have an extensive experience building Continue reading

What Drives Innovation in Business?

The world is running competition. The more businesses that pop up, the more the competition increases. The increase in competition gives birth to a concept called “innovation.” Innovation is a concept that isn’t foreign, and after every few decades, there comes a shift in the world where innovation takes over. People nowadays shift very fast from new ideas to other ideas, so businesses need to keep up with that. They need to be able to produce ideas that are new, interesting, and innovative. 

The question arises, what drives innovation in business and what is business innovation in the first place? 

What is Business Innovation?

Business innovation is when businesses and companies bring new ideas, plans, and services to their customers, which will help not only boost their popularity but also help boost their revenue and profit. Innovations in business keep them relevant through time and make them the top business they want to refer to. 

Why a Business Needs Innovation?

Another question that many business owners ask a lot is, what drives innovation in business? What makes it a driving force that essentially propels a business from a small-time business to a big company? Here Continue reading

Should We Embrace Points of Failure?

failure-pic-1

There was a tweet making the rounds this last week that gave me pause. Max Clark said that we should embrace single points of failure in the network. His post was an impassioned plea to networking rock stars out there to drop redundancy out of their networks and instead embrace these Single Points of Failure (SPoF). The main points Mr. Clark made boil down to a couple of major statements:

  1. Single-device networks are less complex and easier to manage and troubleshoot. Don’t have multiple devices when an all-in-one works better.
  2. Consumer-grade hardware is cheaper and easier to understand, therefore it’s better. Plus, if you need a backup you can just buy a second one and keep it on the shelf.

I’m sure more networking pros out there are practically bristling at these suggestions. Others may read through the original tweet and think this was a tongue-in-cheek post. Let’s look at the argument logically and understand why this has some merit but is ultimately flawed.

Missing Minutes Matter

I’m going to tackle the second point first. The idea that you can use cheaper gear and have cold standby equipment just sitting on the shelf is one that I’ve heard of many Continue reading

Welcome to Technology Short Take #142! This time around, the Networking section is a bit light, but I’ve got plenty of cloud computing links and articles for you to enjoy, along with some stuff on OSes and applications, programming, and soft skills. Hopefully there’s something useful here for you!

  • Bill Doerrfeld discusses the use of WebAssembly to extend the Envoy proxy here after a discussion with Idit Levine, CEO and founder of Solo.io. Envoy is increasingly becoming an important component in many cloud-native networking solutions, so the ability to extend or customize Envoy’s behavior is quite important in my opinion.

Having a sensor to sense things is one story, Having an on-field sensor is another story in itself. While powering up the sensor and weather proofing is not the intention of this blog post but sure they are the other aspects that one needs to address before moving to higher layer communications.

Growth In Green House – Problem is this Indian variant likes very specific Humidity and Temp and I have to measure Humidity/ Temperature/Ambient Light to know what is helping it. I got great
success only once out of 3 times of sowing

Issue – Have a sensor on Field, make sure it communicates itself to AWS IOT end platform. This is not that simple, that too without using high cost end products which abstracts everything from end-user. To put it in simple terms, you have a field or a farm which is quite away from your home and without a power resource, what would you do ?

Lora is one the most effective option that works for us, while I did setup a Gateway and end-node Lora Device, this post aims at something more simple without involving Lora, I will cover Continue reading
