In March 2024, I received my first PR from an airplane: Sander Steffann was flying to South Africa to deliver an Ansible training and fixed a minor annoyance in the then-new multilab feature.Of course, I wanted to know more about his setup, but it took us over a year and a half till we managed to sit down (virtually) and chat about it, the state of…

When I first met David Gee, he worked for a large system integrator. A few years later, he moved to a networking vendor, worked for a few of them, then for a software vendor, and finally decided to start his own system integration business. Obviously, I wanted to know what drove him to make those changes, what lessons he learned working in various …

This podcast introduction was written by Nick Buraglio, the host of today’s podcast. In today’s evolving landscape of whitebox, brightbox, and software routing, a small but incredibly comprehensive routing platform called FreeRTR has quietly been evolving out of a research and education service provider network in Hungary. Kevin Myers of IPArchitec…

This podcast introduction was written by Nick Buraglio, the host of today’s podcast. In the original days of this podcast, there were heavy, deep discussions about this new protocol called “OpenFlow”. Like many of our most creative innovations in the IT field, OpenFlow came from an academic research project that aimed to change the way that we as o…

In early May 2020 I wrote a blog post introducing SuzieQ, a network observability platform Dinesh Dutt worked on for the last few years. If that blog post made you look for more details, you might like the Episode 111 of Software Gone Wild in which we went deeper and covered these topics: How does SuzieQ collect data What data is it collecting from…

A while ago we discussed a software-focused view of Network Interface Cards (NICs) with Luke Gorrie, and a hardware-focused view of them with Or Gerlitz (Mellanox), Andy Gospodarek (Broadcom) and Jiri Pirko (Mellanox). Why would anyone want to implement features in hardware and not in software, and what would be the best hardware implementation? We…

This podcast introduction was written by Nick Buraglio, the host of today’s podcast. As private overlays are becoming more and more prevalent and as SD-WAN systems and technologies advance, it remains critical that we continue to investigate how we think about internetworking. Even with platforms such as Slack Nebula, Zerotier, or the wireguard bas…

No, we were not talking about IP fabrics in general - IP Fabric is a network management software (oops, network assurance platform) Gian Paolo discovered a while ago and thoroughly tested in the meantime. He was kind enough to share what he found in Episode 107 of Software Gone Wild, and as Chris Young succinctly summarized: “it’s really sad what w…

Everyone is talking about FRRouting suite these days, while hidden somewhere in the background OpenBGPD has been making continuous progress for years. Interestingly, OpenBGPD project was started for the same reason FRR was forked - developers were unhappy with Zebra or Quagga routing suite and decided to fix it. We discussed the history of OpenBGPD…

Sick-and-tired of intent-based GUIs that are barely better than CiscoWorks on steroids? How about asking Siri-like assistant queries about network state in somewhat-limited English and getting replies back in full-blown sentences? Warning: you might be reentering the land of unicorns driving flying DeLoreans... but then keep in mind what Arthur Cla…

Imagine you would have a system that would read network device configurations, figure out how those devices might be connected, reverse-engineer the network topology, and be able to answer questions like “what would happen if this link fails” or “do I have fully-redundant network” or even “how will this configuration change impact my network”. Welc…

Remember how Nick Buraglio tried to use OpenDaylight to build a small part of SuperComputing conference network… and ended up with a programmable patch panel? This time he repeated the experiment using Faucet SDN Controller – an OpenFlow controller focused on getting the job done – and described his experience in Episode 101 of Software Gone Wild. …

We love to claim that we’re engineers and yet sometimes we have no clue how technology we use really works and what its limitations are… quite often because understanding those limitations would involve diving pretty deep into math (graphs, queuing and system reliability quickly come to mind).

In recent years Linux networking started evolving at an amazing pace. You can hear about all the cool new stuff at netdev conference… or listen to Episode 94 of Software Gone Wild to get a CliffsNotes version. Roopa Prabhu, Jamal Hadi Salim, and Tom Herbert joined Nick Buraglio and myself and we couldn’t help diverging into the beauties of tc, and …
