Just Published: SDN and OpenFlow – The Hype and the Harsh Reality

If you’re a regular reader of my blog, you know that I spent a lot of time during the last three years debunking SDN myths, explaining the limitations of OpenFlow and pointing out other technologies one could use to program the network.

During the summer of 2014 I organized my SDN- and OpenFlow-related blog posts into a digital book. I want to make this information as useful and as widely distributed as possible – for a limited time you can download the PDF free of charge.

  1. I don't have an account or G+, can you make a public link please?
    1. Sorry - you want to get something for free, you have to follow some rules ;)

      I might add LinkedIn support later on, but it will take a while.
  2. I don't mind joining your site and getting news letters etc, but don't have money for webinars. Can I sign up without purchasing (I am a CS student)?
    1. There's ton of free stuff on my web site, from videos and presentations to blog posts. You'll find some of that at blog.ipspace.net and demo.ipspace.net (and of course you can register to download the book ;).

      Enjoy! Ivan
