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.

I love listening to Scott Lowe’s Full Stack Journey podcast, so I was totally delighted when he asked me to participate. The results: FSJ Episode#8. Enjoy!

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.

Now that we know which definitions of SDN make no sense (and which one might) let’s see what a typical architecture of an SDN solution might look like.

I described some of them in the SDN 101 webinar, for more details watch the SDN Architectures and Deployment Guidelines webinar.

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.

During the Introduction to SDN webinar I covered numerous potential definitions:

• It’s the separation of control and data plane;
• It’s software-based packet forwarding;
• It’s open networking and whitebox switching;
• It’s network programmability and device APIs.

I find all of these definitions too narrow or even misleading. However, the “SDN is a layer of abstraction” one is not too bad (see also RFC 1925 section 2.6a).

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.

In our journey toward two-switch data center we covered:

• The overall idea;
• The need for high-density server virtualization (most of the times).

It’s time for the next step: get rid of legacy technologies like six 1GE interfaces per server or two FC interface cards in every server.
