IP Fabric with Gian-Paolo Boarina on Software Gone Wild

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 ;)

OpenBGPD with Claudio Jeker on Software Gone Wild

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, its current deployments and future plans with Claudio Jeker, one of the main OpenBGPD developers, in Episode 106 of Software Gone Wild.

Net2Text: Natural-Language Interface to Network Operations

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 Clarke had to say on this topic ;).

Welcome to Net2Text, another proof-of-concept tool created by the group led by Laurent Vanbever… who joined us for a short chat to discuss it, resulting in Episode 105 of Software Gone Wild.

Intent-Based Networking with Batfish on Software Gone Wild

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”. Welcome to Batfish.

Interested? You’ll find more in Episode 104 of Software Gone Wild.

Device Configuration Synthesis with NetComplete on Software Gone Wild

When I was still at university the fourth-generation programming languages were all the hype, prompting us to make jokes along the lines “fifth generation will implement do what I don’t know how

The research team working in Networked Systems Group at ETH Zurich headed by prof. Laurent Vanbever got pretty close. The description of their tool says:

Programmable Packet Forwarding Pipelines Using P4 on Software Gone Wild

Every time a new simple programming language is invented, we go through the same predictable cycle:

  • Tons of hype;
  • Unbounded enthusiasm when people who never worked in target environment realize they could get something simple done in a short time;
  • Ever-worsening headaches as the enthusiasts try to get a real job done with the shiny new tool;
  • Disappointment;
  • A more powerful language is invented to replace the old one.

A few years ago we experienced the same cycle when OpenFlow was the-one-tool-to-bind-them all.

Using Faucet to Build SC18 Network with OpenFlow

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 started with the usual “what problem were you trying to solve” and quickly started teasing apart the architecture and got geekily focused on interesting things like:

Smart NICs and Related Linux Kernel Infrastructure

A while ago we did a podcast with Luke Gorrie in which he explained why he’d love to have simple, dumb, and easy-to-work-with Ethernet NICs. What about the other side of the coin – smart NICs with their own CPU, RAM and operating system? Do they make sense, when and why would you use them, and how would you integrate them with Linux kernel?

We discussed these challenges with Or Gerlitz (Mellanox), Andy Gospodarek (Broadcom) and Jiri Pirko (Mellanox) in Episode 99 of Software Gone Wild.

High-Speed IPsec on Snabb Switch on Software Gone Wild

In previous Software Gone Wild episodes we covered Snabb Switch and numerous applications running on it, from L2VPN to 4over6 gateway and integration with Juniper vMX code.

In Episode 98 we focused on another interesting application developed by Max Rottenkolber: high-speed VPN gateway using IPsec on top of Snabb Switch (details). Enjoy!

Network Reliability Engineering on Software Gone Wild

In summer 2018 Juniper started talking about another forward-looking concept: Network Reliability Engineering. We wanted to find out whether that’s another unicorn driving DeLorean with flux capacitors or something more tangible, so we invited Matt Oswalt, the author of Network Reliability Engineer’s Manifesto to talk about it in Episode 97 of Software Gone Wild.

netdev 0x12 Update on Software Gone Wild

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 the intricacies of low-latency forwarding before coming back on track and started discussing cool stuff like:
