SDN Terminology from RFCs?
80% of your job in networking is getting you and your co-worker to agree to what the terms mean.
That paraphrase comes from one of my three networking profs in college, from literally 30 years ago. But that statement is still true today. Getting to a shared understanding of what we mean helps in any conversation about networking, and failing to truly understand the terminology can cause problems.
SDN promises many things, but it certainly has a big impact on networking terminology. SDN introduces many new terms, but it also redefines some terms and reemphasizes the underlying concepts behind other long-used terms.
And then there are no terminology police to run around and make us all use terms the same way. It’s enough to drive you crazy!
Today’s post (and possibly a few more) explores some attempts to answer some of the questions about what SDN terms to use and what they mean. In this post, I’ll look at a relatively new Internet RFC: the SDN Layers and Architecture Terminology RFC.
Overview: Terminology is a Challenge

IT/IT: Merge Lane
You’re probably living in a bubble (or sleeping on a mat in the data center — remind me to tell you about the sleeping bag I carried in the back of my truck for a while…) if you’ve not heard about the Nokia/Alcatel merger. What’s interesting, from a network engineering perspective, is what this means. To get a better idea, it’s important to consider another story posted this last week.
The white box switching market could see some monumental change within even one year, according to Dell’Oro Group analyst Alan Weckel. That’s mainly because of the rise of hyperscale cloud players — specifically Amazon, Facebook, Google, and Microsoft. Their buying power has grown substantially in the past few years — and white boxes have progressed rapidly during that time, too.
So what does white box have to do with the Nokia/ALU merger? Just about everything, most likely. To better understand, we need to first posit that the world is going software. Not that we won’t have hardware any longer, but rather that the hardware is going to become much less interesting over the next five to ten years as the software used to run the hardware is separated out and Continue reading
Hardware Gateways in Overlay Virtual Networks
Whenever I’m running an SDDC workshop or doing on-site SDN/SDDC-related consulting, the question of hardware gateways between overlay virtual networks and physical world inevitably pops up.
My usual answer: You have to understand (A) what type of gateway you need, (B) what performance you need and (C) what form factor will give you that performance. For more details, watch the Hardware Gateways video from Scaling Overlay Virtual Networks webinar
