Where are we with SDN in May 2015 ?
There is so much to talk about in SDN that I couldn’t finish any of the dozen or so blog posts that I started in the last three weeks. Instead I created a 15 minute Keynote presentation that had the key points that I wanted to blog about.

On I-Shaped and T-Shaped Skills
Several of the conversations I had at the recent RIPE70 meeting were focused on career advice (usually along the lines of “which technology should I focus on next”) and inevitably we ended up discussing the benefits of T-shaped skills versus I-shaped skills… and I couldn’t resist drawing a few graphs illustrating them.

I have moved to a new blogging platform! The timing was interesting, since the wordpress installation on which Keeping It Classless has operated for so long is about 5 years old (I operated on an older domain before Keeping It Classless was born). WOW. Five years is a long time in blog years. I could not have possibly predicted back then what this blog would do for me. In going over these old posts, I saw a very interesting progression of my own skillsets and mentality, and I figured I’d share.A New Home: Looking Back

(Side note, this blog post was written and then forgotten about quite a while ago, So I’ve finished it off, it was halfway done.)
While on holiday in the evenings with downtime to spare, I had realised that
MPLS VPN’s over mGRE
This blog post outlines what “MPLS VPNs over mGRE” is all about as well as provide an example of such a configuration.
So what is “MPLS VPNs over mGRE”? – Well, basically its taking regular MPLS VPN’s and using it over an IP only core network. Since VPN’s over MPLS is one of the primary drivers for implementing an MPLS network in the first place, using the same functionality over an IP-only core might be very compelling for some not willing/able to run MPLS label switching in the core.
Instead of using labels to switch the traffic from one PE to another, mGRE (Multipoint GRE) is used as the encapsulation technology instead.
Be advised that 1 label is still being used however. This is the VPN label that’s used to identify which VRF interface to switch the traffic to when its received by a PE. This label is, just as in regular MPLS VPN’s, assigned by the PE through MP-BGP.
So how is this actually performed? – Well, lets take a look at an example.
The topology I will be using is as follows:

Moving Soon!
I would like to take the opportunity to let you all know that Keeping It Classless will be moving to a different blogging platform in the near future. For the vast majority of you, this will not be a problem. My intent is to keep as much as possible consistent between moves.
However, some of you subscribe to my blog using some WordPress-specific features such as email subscription, as well as following me through the WordPress service itself. After the move, these services will have no way of being updated. If this applies to you, please check out the following options:
- I will continue to link to each new blog post to my social media accounts, such as Twitter, Facebook, Google+, and LinkedIn. Follow me at whichever you prefer, and you’ll get all new posts in the relevant news feed.
- I will continue to provide an RSS feed at http://keepingitclassless.net/feed/. Currently this redirects to feedburner, which is likely what you have in your RSS reader, if you’ve already done this. The transition away from WordPress will break this automatic redirection, but don’t worry – feedburner will continue to deliver post updates to you, at least until I Continue reading
Introducing the Citizens of Tech Podcast
Citizens of Tech is not a show about gadgets and apps, at least not specifically. It's not a show about networking. It's not a constipated show about IT. Rather, it's a show for nerds who like science, gaming, books, contrarian thinking, entertainment, space exploration, transportation, energy, complex world problems, and anything else that's somehow technology-related. Sure, that might include gadgets, apps, IT, and so on, but we're trying to appeal to a certain kind of mind -- probably yours -- and not a certain kind of industry.Citizens of Tech 003 – Racing Cricket Phone Turbines
Eric in a mitre. Cricket protein. Micro wind turbines. Stash your cash. Blue crude. RF into power. Wikimedia's money. Carly for POTUS. A racing simulator that can kill you. All this and more on this week's Citizens of Tech.
