Software Gone Wild by ipSpace.net

We did several podcasts describing how one could get stellar packet forwarding performance on x86 servers reimplementing the whole forwarding stack outside of kernel (Snabb Switch) or bypassing the Linux kernel and moving the packet processing into userspace (PF_Ring).

Now let’s see if it’s possible to improve the Linux kernel forwarding performance. Thomas Graf, one of the authors of Cilium claims it can be done and explained the intricate details in Episode 64 of Software Gone Wild.

In March 2016 my friend Matt Oswalt announced a distributed network testing framework that he used for validation in his network automation / continuous integration projects. Initial tests included ping and DNS probes, and he added HTTP testing in May 2016.

The project continues to grow (and already got its own Github and documentation page) and Matt was kind enough to share the news and future plans in Episode 63 of Software Gone Wild.

To ask questions about the project, join the Todd channel on networktocode Slack team (self-registration at slack.networktocode.com)

When LinkedIn announced their Project Falco I knew exactly what one of my future Software Gone Wild podcasts would be: a chat with Russ White (Mr. CCDE, now network architect @ LinkedIn).

It took us a long while (and then the summer break intervened) but I finally got it published: Episode 62 is waiting for you.

Does it make sense to run OpenStack on top of VMware infrastructure? How well does NSX work as a Neutron plug-in? Marcos Hernandez answered these questions (and a lot of others) in the Episode 61 of Software Gone Wild (admittedly after a short marketing pitch in the first 10 minutes).

Software Gone Wild podcast is well into its toddler years and it was time for a teambuilding exercise. Just kidding – we wanted to test new tools and decided to discuss the vacation experiences and podcast ideas while doing that.

On a more serious note: we’re always looking for cool projects, implementations and ideas. Contact us at podcast (-the weird sign-) ipspace.net.

A few days after I published a blog post arguing that most service providers cannot possibly copy Google’s ideas Giacomo Bernardi wrote a comment saying “well, we managed to build our own gear.”

Initially I thought they built their own Linux distribution on top of x86 server, but what Giacomo Bernardi described in Episode 59 of Software Gone Wild goes way beyond that:

A while ago Big Switch Networks engineers realized there’s a cool use case for their tap aggregation application (Big Tap Monitoring Fabric) – an intelligent patch panel traffic steering solution used as security tool chaining infrastructure in DMZ… and thus the Big Chain was born.

Curious how their solution works? Listen to Episode 58 of Software Gone Wild with Andy Shaw and Sandip Shah.

A few weeks after I published Docker Networking podcast, Brent Salisbury sent me an email saying “hey, we have experimental Macvlan and Ipvlan support for Docker” – a great topic for another podcast.

It took a while to get the stars aligned, but finally we got Brent, Madhu Venugopal, John Willis and Nick Buraglio on the same Skype call resulting in Episode 57 of Software Gone Wild.
