On today's Tech Bytes we talk with J-U-B Engineering about how the company boosted employee productivity with an SD-WAN from Silver Peak. Silver Peak is our sponsor. Our guest is Tory Adams, Director of Information Technology at J-U-B Engineering.

What’s the next logical automation step after you cleaned up device configurations and started using configuration templates? It obviously depends on your pain points; for Anne Baretta it was a network inventory database stored in SQL tables (and thus readily accessible from his other projects).

Migrating a privacy-safe information extraction system to a software 2.0 design, Sheng, CIDR’20
This is a comparatively short (7 pages) but very interesting paper detailing the migration of a software system to a ‘Software 2.0’ design. Software 2.0, in case you missed it, is a term coined by Andrej Karpathy to describe software in which key components are implemented by neural networks. Since we’ve recently spent quite a bit of time looking at the situations where interpretable models and simple rules are highly desirable, this case study makes a nice counterpoint: it describes a system that started out with hand-written rules, which then over time grew complex and hard to maintain until meaningful progress had pretty much slowed to a halt. (A set of rules that complex wouldn’t have been great from the perspective of interpretability either). Replacing these rules with a machine learned component dramatically simplified the code base (45 Kloc deleted) and set the system back onto a growth and improvement trajectory.
A really interesting thing happens when you go from developing a Software 1.0 (i.e., traditional software) to a Software 2.0 system. In Software 1.0 we spend Continue reading
Hello my friend,
We are slowly but surely start talking about more and more useful and interesting topics staying yet at a basic level. Today you will learn about variables in Python, as variables are obviously the basic building block of any tool.
Don’t wait to be kicked out of IT business. Join our network automation training to secure your job in future. Come to NetDevOps side.
How does the training differ from this blog post series? Here you get the basics and learn some programming concepts in general, whereas in the training you get comprehensive set of knowledge with the detailed examples how to use Python for the network and IT automation. You need both.
We will learn how to create and use in Python 3.8 several types of the variables such as:
The different types of variables are used for the different purposes, that’s why the more variables’ type you know, the better code you can write. We must admit that this list of the variables isn’t complete. That is why in the next couple of blogposts you will see Continue reading
MikroTik announced VxLAN support on Valentine’s Day (Feb 14th) of 2020.
This is a significant feature addition for RouterOSv7 as it will pave the way for a number of other additions like EVPN in BGP.
It will also give MikroTik the ability to appeal to enterprises and data centers that might need cost-effective VxLAN capable devices.
Service Providers are also moving towards VxLAN as a future replacement for VPLS so this is helpful for that market as well.
Download the OVA here:
https://download.mikrotik.com/routeros/7.0beta5/chr-7.0beta5.ova
The initial release of VxLAN is based on unicast and multicast to deliver Layer 2 frames.
As there is no EVPN support, the VTEPs must be manually configured for each endpoint in a full mesh configuration.
The VxLAN interface can then be bridged to a physical ethernet port or VLAN interface to deliver the traffic to the end host.
Here is an overview lab in EVE-NG with a basic setup using 3 linux servers on the same 10.1.1.0/24 subnet which is carried as an overlay by VxLAN.
VxLAN reachability for VTEPs is acheived with OSPFv2 and loopback addresses.

Dinesh Dutt, a pragmatic IP routing guru, the mastermind behind great concepts like simplified BGP configuration, and one of the best ipSpace.net authors, finally decided to start blogging. His first article: describing the impact of having 256 100GE ports in a single ASIC (Tomahawk 4). Hope you’ll enjoy his musings as much as I did ;)

When talking about high-end HPC systems in the world, much of the attention often is paid to the massive supercomputers that are being developed by the likes of system makers Cray (now part of Hewlett Packard Enterprise and the main contractor on two exascale systems), Fujitsu, Atos, IBM, and others along with component makers Intel (which is a primary contractor on one exascale system), AMD, and Nvidia. …

As more abstractions and automation layers creep into the network, are network engineers losing their grasp on core fundamentals? Three grumpy old network engineers ponder this question, talk about how we got here, and what can be done about it. Our guests are Chris Young and Ivan Pepelnjak.

Security on your mind: The Internet Society’s Chapter in Benin recently hosted a conference focused on online security and on connectivity issues. Much of the discussion focused on instability of connections in the country, with participants concerned about degraded connections. Participants also talked about limited coverage for mobile services. On the topic of security, speakers urged Internet users to regularly change their passwords, avoid default passwords, and prevent third-party apps from connecting to the services they use.
Secure messages: The Israeli Chapter has focused on the security of messaging and social media apps recently. The Chapter recently posted a guide on how to prevent Instagram accounts from being hacked and a guide on how users can protect their privacy on the Tik Tok messaging app.
Privacy for the young ones: Meanwhile, the Chapter in Portugal, working with the Kids Safe on the Net project, has launched an initiative to improve awareness among Portuguese youth about the importance of online privacy and how they can maintain their privacy.
Good privacy: The Netherlands Chapter recently gave its support to the Good ID initiative, an approach to identity management that prioritizes data privacy and security. Good ID aims to give Internet users Continue reading
