NetDev 0x13 on Software Gone Wild

As I started Software Gone Wild podcast in June 2014, I wanted to help networking engineers grow beyond the traditional networking technologies. It’s only fitting to conclude this project almost seven years and 116 episodes later with a similar theme Avi Freedman proposed when we started discussing podcast topics in late 2020: how do we make networking attractive to young engineers. Elisa Jasinska and Roopa Prabhu joined Avi and me, and we had a lively discussion that I hope you’ll find interesting. Listen to the podcast

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 IPArchitechs brought this to my attention around March of 2019, at which point I went straight to work with it to see how far it could be pushed.Read more …

Remember my rant how “fail fast, fail often sounds great in a VC pitch deck, and sucks when you have to deal with its results”? Streaming telemetry is no exception to this rule, and Avi Freedman (CEO of Kentik) has been on the receiving end of this gizmo long enough to have to deal with several generations of experiments… and formed a few strong opinions. Unfortunately Avi is still a bit more diplomatic than Artur Bergman – another CEO I love for his blunt statements – but based on his NFD16 presentation I expected a lively debate, and I was definitely not disappointed.

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 operators managed, configured, and even thought about networking fundamentals. For the most part, this project did what it intended, but once the marketing machine realized the flexibility of the technology and its potential to completely change the way we think about vendors, networks, provisioning, and management of networking, they were off to the races. We all know what happened next.Read more …

This podcast introduction was written by Nick Buraglio, the host of today’s podcast. As we all know, BGP runs the networked world. It is a protocol that has existed and operated in the vast expanse of the internet in one form or another since early 1990s, and despite the fact that it has been extended, enhanced, twisted, and warped into performing a myriad of tasks that one would never have imagined in the silver era of internetworking, it has remained largely unchanged in its operational core. The world as we know it would never exist without BGP, and because of the fact that it is such a widely deployed protocol with such a solid track record of “just working”, the transition to a better security model surrounding it has been extraordinarily slow to modernize.Read more …

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 network devices What can you do with that data How can you customize and extend SuzieQ Listen to the podcast

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 discussed these dilemmas with Silvano Gai in Episode 110 of Software Gone Wild podcast.Read more …

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 based TailScale becoming a mainstream staple of many businesses, the question of “what is next” is being asked by an ambitious group of researchers.Read more …

The last Software Gone Wild podcast recorded in 2019 focused on advances in Linux networking - in particular on interesting stuff presented at NetDev 0x13 conference in Prague. The guests (in alphabetical first name order) Jamal Hadi Salim, Shrijeet Mukherjee, Sowmini Varadhan, and Tom Herbert shared their favorite topics, and commented on the future of Linux networking.Read more …

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 we still get excited about something 30 years after it was first promised”… but maybe this time it really works ;) Listen to the podcast
