I struggled with this whole SDN/NVF/insert marketing term for a while at first, until I sat down and actually though about. When I strip away all the foo, what I'm left with is breaking things down to pieces and and putting logo blocks together in a way that best suits what I'm doing. It is really going back to the way things were a long time ago in the days of 12/2400 baud models and 56k frame relay. It doesn't help vendors vendors that want to sell you over priced foo for features you don't really need. It lets you, if you have clue build your own right bits. It will see some vendors evolve, new vendors of their brand of foo appear and some vendors die, but end of day, its no different then most of were doing back in the "good ol days"
The way I see it, the whole SDN/NFV talk has finally devolved into automation (separating the control and data plane is sooooo 2013). Automation is not new - a lot of networks have been automating for a long time now, albeit in custom ways that only worked for them... ummh, rephrase: was not tested in other networks. The reason I see SDN/NFV becoming a thing is just to have a standard way of automating. That's it. Mark.
