Cisco has stopped short of completely separating the data plane and control panel. Rather, they've rolled out a framework to address the desire for a more programmable networking layer while protecting intelligence within the delivery plane. Tracy Corbo just spent a week at C-scape and has some key takeaways about Cisco, SDN and Cisco ONE.
