Replacing a Network Element Config System with Git

In this post I’ll explore replacing the heart of a network operating system’s configuration mechanism with the software developers take on version control. It can be argued that network operating systems, or at least good ones, already have a version control system. It’s that very system that allows you to roll back and carry out operations like commit-confirmed. More specifically, this is a version control system like Git but not specifically git.

As my day job rotates around Junos, I’ll concentrate on that. So why would anyone want to rip out the heart of Junos and replace it with a git backed directory full of configuration snippets? Software developers and now automation skilled engineers want the advantages of being able to treat the network like any other service delivering node. Imagine committing human readable configuration snippets to a network configuration directory and having the network check it out and do something with it.

Junos already has a configuration engine capable of rollbacks and provides sanity through semantic and syntax commit time checks. Mgd (the service you interact with) provides mechanisms to render interfaces through YANG models and generates the very configuration tree you interact with. You could say mgd takes Continue reading

Why we cannot live without a Telco Cloud, and how does one build one?

There are a more mobile phone connections (~7.9 billion) than the number of humans (~7.7 billion) colonising this planet.

Let me explain.

Clearly, not every person in the world has a mobile device. Here we’re talking about mobile connections that come from people with multiple devices (dual SIMs, tablets) and other integrated devices like cars, and other smart vehicles, and of course the myriad IOT devices. I don’t have to go too far — my electric 2 wheeler has a mobile connection that it uses to cheerfully download the updated firmware version and the software patches every now and then.

While the global population is growing at 1.08% annually, the mobile phone connections are growing at 2.0%. We will very soon be outnumbered by the number of mobile subscriptions, all happily chatting, tweeting and in general sending data over the network. Some of it would need low latency and low jitter, while some may be more tolerant to the delays and jitter.

So, what’s the big deal with mobile connections growing?

Well, historically most people have used their mobile phones to talk; to catch up on all the gossip on your neighbours and relatives.

vlog. Episode 5. NetLdn: Networking for Networkers

Hello my friends,

It is always cool to talk about various network technologies with the engineers from industry, and to meet some awesome chaps. I had a pleasure to attend such an event in London in the last months. Learn my findings on that.

CY2019 Episode 5 // NetLdn with James Bensley and Richard Patterson

In this episode, together with James Bensley and Richard Patterson from Sky we discuss the the NetLdn event series. The event, where you can discuss network technoligies with the peers and, perhaps, make some friends.

Two AMD Epyc processors crush four Intel Xeons in tests

Tests by the evaluation and testing site ServeTheHome found a server with two AMD Epyc processors can outperform a four-socket Intel system that costs considerably more.If you don’t read ServeTheHome, you should. It’s cut from the same cloth as Tom’s Hardware Guide and AnandTech but with a focus on server hardware, mostly the low end but they throw in some enterprise stuff, as well.ServeTheHome ran tests comparing the AMD Epyc 7742, which has 64 cores and 128 threads, and the Intel Xeon Platinum 8180M with its 28 cores and 56 threads. The dollars, though, show a real difference. Each Epyc 7742 costs $6,950, while each Xeon Platinum 8180M goes for $13,011. So, two Epyc 7742 processors cost you $13,900, and four Xeon Platinum 8180M processors cost $52,044, four times as much as the AMD chips.To read this article in full, please click here

Running sflowtool using Docker

The sflowtool command line utility is used to convert standard sFlow records into a variety of different formats. While there are a large number of native sFlow analysis applications, familiarity with sflowtool is worthwhile since it provides a simple way to verify receipt of sFlow, understand the contents of the sFlow telemetry stream, and build simple applications through custom scripting.

The sflow/sflowtool Docker image provides a simple way to run sflowtool. Run the following command to print the contents of sFlow packets:
$ docker run -p 6343:6343/udp sflow/sflowtool

IT Hero Culture

I’ve written before about rock stars and IT super heroes. We all know or have worked with someone like this in the past. Perhaps we still do have someone in the organization that fits the description. But have you ever stopped to consider how it could be our culture that breeds the very people we don’t want around?

Keeping The Lights On

When’s the last time you got recognition for the network operating smoothly? Unless it was in response to a huge traffic spike or an attack that tried to knock you offline, the answer is probably never or rarely. Despite the fact that networks are hard to build and even harder to operate, we rarely get recognized for keeping the lights on day after day.

It’s not all that uncommon. The accounting department doesn’t get recognized when the books are balanced. The janitorial staff doesn’t get an exceptional call out when the floors are mopped. And the electric company doesn’t get a gold star because they really did keep the lights on. All of these things are examples of expected operation. When we plug something into a power socket, we expect it to work. When we plug a router Continue reading

How the California Consumer Privacy Act (CCPA) will affect you and your business | TECH(talk)

The California Consumer Privacy Act (CCPA) is, in some ways, similar to Europe's GDPR. This rule, which goes into effect in 2020, gives individual users more ownership over their own data. Users can even refuse to allow companies to sell their online data. As the compliance deadline approaches, CSO Online contributor Maria Kolokov and senior editor Michael Nadeau discuss with Juliet how CCPA may shift business models, change online behavior and reveal where exactly our data has been. Some tech companies, like Google, are even trying to exempt themselves from regulation. Failure to adhere to the rule could be an "extinction level" event.
