A provocative article. My reaction is too long to fit as a comment, but I posted a blog entry at cplane.net (FKA layerzngn.com) with a link to your article. What strikes me is growing, not lessening, confusion over what SDN is, whether OpenFlow is tied to it and whether OpenFlow is closed or open. Another topic for discussion is whether open source is or is not a core attribute. ONF’s no doubt well-intended efforts may be unwittingly contributing to the confusion and uncertainty.
