The 2022 French Presidential election leaves its mark on the Internet

The first round of the 2022 French presidential elections were held this past Sunday, April 10, 2022, and a run-off will be held on April 24 between the top two candidates, Emmanuel Macron and Marine Le Pen. Looking at Internet trends in France for Sunday, it appears that when people were voting Internet traffic went down, and, no surprise, it went back up when results are coming in — that includes major spikes to news and election-related websites.

Cloudflare Radar data shows that Sundays are usually high-traffic days in France. But this Sunday looked a little different.

The seven-day Radar chart shows that there was a decrease in traffic compared to the previous Sunday between 08:00 and 16:00 UTC, that’s 10:00 and 18:00 in local time — bear in mind that polling stations in France were open between 08:00 and 19:00 (or 20:00 in big cities) local time. So, the decrease in traffic was ‘inside’ the period when French citizens were allowed to vote.

That’s a similar trend we have seen in other elections, like the Portuguese one back in January 2022.

The time of the French election day with the largest difference compared to the previous Sunday was 14:00 Continue reading

Expanding DevOps With Infrastructure As Code

The hyperscalers have taught us many lessons in the past two decades, and one of them is that everything that can be defined in software should be so that it can be controlled automatically and programmatically – and that goes double for hardware, which has required so much human babysitting over the decades. …

Device Management From The Ground Up: Part 8 – Configuration Archiving

If you want to create routine backups on your device or a local server, Cisco offers the “archive” feature on its IOS platform. I cover the various options we can pass to the archive command and go over an example of its use.

9 hot jobs in the evolving data center

As data centers evolve, the skills needed to run them change as well, creating both a challenge and opportunity for current data-center workers.By necessity, modern data centers are at the forefront of efficiency for energy consumption, space utilization and automation. That efficiency extends to the personnel that staffs them and who must swiftly implement hardware, software, and architecture changes as best practices improve. That calls for new roles in administration, management, and planning.Existing career fields and legacy skill sets won’t cut it in many cases, but IT pros will be able to augment their existing skills to fill new roles as they open up—jobs with a more forward-looking focus.To read this article in full, please click here

Creating VRF Lite Labs With netlab

I always found VRF lab setups a chore. On top of the usual IPAM tasks you have to create VRFs, assign route targets and route distinguishers, do that on every PE-router in your lab… before you can start working on interesting things.

I tried to remove as much friction as I could with the netlab VRF configuration module – let me walk you through a few simple examples¹ which will also serve to illustrate the VRF configuration differences between Cisco IOS and Arista EOS.

Events. My first MPLS World Congress: Impressions, Feelings, and Raise of AI.

Hello my friend,

This year I had an incredible opportunity to attend an event, which I wanted to attend for quite a bit back in past, when I was working for service providers (e.g., Vodafone, A1 BLR / Telekom Austria Group). The full name of the event is MPLS SDN and AI World Congress 2022, or simply #mplswc22.

Thanks

I’m very helpful to my friends and colleagues Pau Nadeu Rabat and Jose Manuel Roman Fernandez Checa for inviting me to take part in the event. 

Brief History of the Event

MPLS SDN AI World Congress is one of the biggest events in the networking industry in the Europe. Originally it was called simple MPLS World Congress (hence, the name #mplswc22) and was aiming to bring together the biggest service providers (like the guys I worked for before, Deutsche Telekom, Orange, etc) and vendors of telecom equipment and software (like, Nokia, which I also Continue reading

Worth Reading: Full-Stack Network Automation

Lívio Zanol Puppim published a series of blog posts describing a full-stack network automation, including GitOps with GitLab, handling secrets with Hashicorp Vault, using Ansible and AWX to run automation scripts, continuous integration with Gitlab CI Runner, and topped it off with a REST API and React-based user interface.

You might not want to use the exact same components, but it’s probably worthwhile going through his solution and explore the source code. He’s also looking for any comments or feedback you might have on how to improve what he did.

Worth Reading: The AI Illusion

Russ White’s Weekend Reads are full of gems, including a recent pointer to the AI Illusion – State-of-the-Art Chatbots Aren’t What They Seem article. It starts with “Artificial intelligence is an oxymoron. Despite all the incredible things computers can do, they are still not intelligent in any meaningful sense of the word.” and it only gets better.

While the article focuses on natural language processing (GPT-3 model), I see no reason why we should expect better performance from AI in networking (see also: AI/ML in Networking – The Good, the Bad, and the Ugly).
