SDN: Software Defined Networks
“SDN Complexity and Reality” by Russ White and Shawn Zandi, was published on page 31 of The Internet Protocol Journal, November 2016 (Volume 19, Number 3). You can download ipj19-3.pdf at http://ipj.dreamhosters.com/.
In the article, White and Zandi, examine the original three crucial elements to the SDN story:
First, SDNs were supposed to remove the intelligence from the distributed control planes and consolidate that intelligence in a centralized controller.

The Internet Is An Imperfect and Hostile Place
The world is an imperfect place. The internet is no exception. The internet has its good days and it has its bad days. Or to be more precise, the internet has its good seconds and its bad seconds.
Blemishes in internet performance arise from many sources. Continue reading Why You Should Care About Impairment Testing of Internet Protocols
Real network conditions are rarely static. Real life networks suffer transient conditions – congestion builds up and dissipates, tree branches wave in the wind across radio links, long distance routing paths change, VoIP call trunks are filled with more calls during working hours than during the evening. Even something as small as a person standing near a wi-fi access point can change the carrying capacity of a network.
KMAX (and our Maxwell Pro) can emulate these kinds of changes.

You’re better off going straight to StackOverflow.com .
That’s the current situation with many technologies, platforms, SDK libraries and command-line interfaces: the documentation is so badly written, or so poorly organized, or so skimpy, that you can safely skip it and just use Stack Overflow as your answer-it-all search engine.

The ESP8266 is very popular among the maker set as a platform for experimentation in the realm of Internet of Things (IoT).
We have been playing around with the ESP8622 micro-controller running NodeMCU. We’ve been loading simple LUA programs onto the ESP8266 to get familiar with its capabilities.
Now that we’re reasonably familiar with its capabilities, it’s time we put ESP8266/NodeMCU to test.

Cloud computing has taken hold of the business world, nearly reaching its saturation point according to multiple industry reports. The business cloud and its cloud testing capabilities are growing at an extremely fast pace due to scalability, adaptability, cost-effectiveness, and efficiency across nearly every industry.
Continue reading New Cloud Testing Paradigm Comes With Challenges that Network Emulators Can Solve
When evaluating your application for deployment, it is critical to know exactly how it will respond to a variety of network conditions. In some cases, this means going out into the field in search of live, real-world testing scenarios that can be used to test app functionality and user-friendliness. Continue reading Network Emulation in the Lab vs. Real-World Network Testing
Many CEOs and business owners think data center relocation involves the simple process of unplugging of a few servers, some careful packaging, and a secure shipment to the next location. IT professionals know that it’s actually a lot more complicated than that.

IDC reports that up to 50% of cloud customers have brought workloads back in house, due to network latency and performance issues, in the cloud. This is an expensive, cumbersome, and counterproductive measure that halts the progress of a company’s technology and growth.
