I always encourage the students attending the Building Network Automation Solutions online course to create solutions for problems they’re facing in their networks instead of wasting time with vanilla hands-on assignments.
Francois Herbet took the advice literally and decided to create a solution that would configure PE-routers and create full-blown device configurations for CE-routers.

Bufferbloat is responsible for much of the poor performance seen in the Internet today and causes latency (called “lag” by gamers), triggered even by your own routine web browsing and video playing.
But bufferbloat’s causes and solutions remind me of the old parable:
It was six men of Indostan, to learning much inclined,
who went to see the elephant (Though all of them were blind),
that each by observation, might satisfy his mind.
……. (six stanzas elided)
And so these men of Indostan, disputed loud and long,
each in his own opinion, exceeding stiff and strong,
Though each was partly in the right, and all were in the wrong!
So, oft in theologic wars, the disputants, I ween,
tread on in utter ignorance, of what each other mean,
and prate about the elephant, not one of them has seen!
John Godfrey Saxe
Most technologists are not truly wise: we are usually like the blind men of Indostan. The TCP experts, network operators, telecom operators, router makers, Internet service operators, router vendors and users have all had a grip *only* on their piece of the elephant.
The TCP experts look at TCP and think “if only TCP were Continue reading
In my personal life, I’ve jumped in the SmartHome head first, but I’ve been really reluctant to blur the lines into my professional life. Recently, I saw something that changed all that. The Microsoft IoT DevKit board.
This is Microsoft hardware product that allows developers to jump into the IoT pool. Specifically, the Microsoft Azure IoT hub pool. This is a very capable board with multiple sensors.
What sensors you ask?
Basically, it’s a really good sensor that can grab the majority of the physical measurements that we want to look at in the IoT world.
Right now, this is really just a tech toy for me. I have no specific projects that I’m trying to achieve. Rather this is a device that I’m using to try and really understand HOW the IoT ecosystem works and ensure my employability in years to come. So I don’t have any specific goals, but that’s really ok because Microsoft has been wonderful enough to supply us with the Microsoft IoT DevKit page over at Github which has a few different projects that allow me to grow Continue reading
If you’re a regular reader of our blog, you probably do a lot of professional work with networking, manage an enterprise data center or play around with networks as a hobby (if you don’t, close your eyes for just a moment and imagine yourself in a well air-conditioned data center). You also likely know about the day-to-day tasks that maintaining a network requires, and how much time they take out of the day. Or, perhaps you’re a director that’s trying to resolve the issues your networking team keeps having. Has it ever occurred to you that there might be a better way to tackle these daily problems? Sure, what you’re doing now works, but there’s so much else you could be doing if the management of these tasks were optimized. That’s where network automation solutions can step in and give you more free time than you could have dreamed of. Why automation? Well, let’s get into what problems it eliminates and the benefits it brings — you can thank us later!
A day in the life of a network engineer includes three layers of regular tasks. At the top, we have troubleshooting operation Continue reading
For over a year now we in the Sarantaporo.gr Non Profit Organization have been in contact with Internet Society in meetings, over online interactions, and through in-person collaboration with people of the organization who visited our village last summer. From the beginning we saw that Internet Society is an organization which we share a lot of common elements with in terms of vision, and that its network is a natural space for our Community Network to be a part of.
In September 2017 we applied for the Internet Society Beyond the Net Funding Programme to approach the organization more closely and pursue funding to finance our Community Network. We are very happy to announce that our proposal was successful and will be funded with $30,000 USD through 2018 and 2019. This grant arrives very timely, in a period of transformation for our Community Network.
Continuously growing since 2010 to expand from Sarantaporo to even more villages in the region, today Sarantaporo.gr Community Network has reached a point where it is no longer possible to keep growing under the previous model, which was heavily dependent on the volunteering work of the nonprofit’s core team. Local inhabitants need to step in and Continue reading
From the fantastic Lines, Radios and Cables (a MUST READ if you’re even remotely interested in this thing called latency):
When we put different colours of light, or wavelengths, onto a single fibre, we call it Wave Division Multiplexing (WDM) which is a complicated way of saying a pretty rainbow […] International trading is powered by rainbows, literally.
In this episode of The Interview from The Next Platform, we talk with Andrew Jones from independent high performance computing consulting firm, N.A.G. about processor and system acquisition trends in HPC for users at the smaller commercial end of the spectrum up through the large research centers.
In the course of the conversation, we cover how acquisition trends are being affected by machine learning entering the HPC workflow in the coming years, the differences over time between commercial HPC and academic supercomputing, and some of the issues around processor choices for both markets.
Given his experiences talking to end users …
HPC System & Processor Trends for 2018 was written by Nicole Hemsoth at The Next Platform.
The platform generates 25 Gb/s of encrypted traffic to test application delivery and network security.
The container components can slash content platform deployment to minutes.
It overlaps with part of the work that OPNFV does.
Qualcomm rejects Broadcom (again); ZTE releases first 5G network slicing solution; AT&T closes on its FiberTower acquisition.
The operator reasserted its claim that it will be first in the U.S. with a nationwide 5G footprint.
Some quick thoughts on networking from my last couple of weeks at Networking Field Day 17 and Tech Field Day Extra at Cisco Live Europe:
Hey, it's HighScalability time:
If you like this sort of Stuff then please support me on Patreon. And I'd appreciate if you would recommend my new book—Explain the Cloud Like I'm 10—to anyone who needs to understand the cloud (who doesn't?). I think they'll learn a lot, even if they're already familiar with the basics.
The combination of the excitement for new video games, the machine learning software revolution, the buildout of very large supercomputers based on hybrid CPU-GPU architectures, and the mining of cryptocurrencies like Bitcoin and Ethereum have combined into a quadruple whammy that is driving Nvidia to new heights for revenues, profits, and market capitalization. And thus it is no surprise Nvidia is one of the few companies that is bucking the trend in a very tough couple of weeks on Wall Street.
But having demand spiking for both its current “Volta” GPUs, which are currently aimed at HPC and AI compute, …
