It would be good if you could also describe the cases where only CP learning is needed, and many other cases which the combination of CP and DP learning would be applied, (I assume pure L2 is out of the scope in nvo3), where the demarcation is and the implications in each case, you could abstract the models/scenarios using the terms and architecture references defined in the doc, and I think any standardized IETF/IEEE technologies could be named out when they are mixed into the combination, or stand alone.
