Whither SDN?

SDN was touted as a separation of control and data planes, with "northbound" APIs to allow "network applications" to transform networks to the desired state. We view SDN as a separation of provisioning and devices, with northbound abstract data models that capture intent, which the SDN system transforms to device level data models. This presentation discusses how these two visions play out, and how the latter model would operate practically, by showing data models in action.
