This week I attended the Open Networking Summit in Santa Clara with 900 of my closest friends. Okay, maybe I am contributing to the hype around Software-Defined Networking (SDN) with a statement like that. It wasn't 900, there were only 899 in attendance (over 100 on a waiting list) and they were not all my friends, but I did meet a lot of really smart people and had a lot of great conversations. Those in attendance ranged from network engineers from large health care providers, senior executives from large service providers, hardware and software vendors, and more than a few venture capital and money management firms. The show seemed to be a good mix of speaking sessions that covered existing implementations, tools, vision for the future etc., as well as expo/demo time to review offerings and better understand the current state of commercially available solutions.
