But even as I spend more time trying to grasp Software Defined Networking (SDN), talking with some of the smartest people in the industry, I find myself still left with some very basic questions that I haven't seen answered yet. So I'm just going to make a list, with the hope that those more in the know might provide answers via links or comments in this blog. The Packet Pushers podcast touched on some of these, but I don't believe answers emerged.
Plenty has been written about the potential economic impacts (both to customers and vendors/suppliers) of more open networking equipment. Considering the size of the market for networking hardware ($50B+) and the incumbent vendors involved, I can understand the focus. But it seems strange (to me at least) that we have so many open technology questions.I'm going to try and group these into categories that span from greenfield environments to large legacy environments, so I can better understand how to get from here to there.
