The Technology looks exciting and seamless providing integration with legacy networks/technologies e.g. MPLS. However I had some questions jumping into my mind after the video, I would love to share :

1- Have there been any tests to verify integration/interoperability with other vendor equipment or the assumption is transformation means replacing all assets with Cisco ones ?

2-The network operation in the legacy was dissected into functionalities i.e. devices. In the transformation those functionalities will be performed vis S/W on SDN and NFV.

3-How much complicated or effort is needed by the Enterprise network designers, operators , administrators to change their line of thought from the legacy ecosystem to the this new ecosystem .?

Example is the processes design and application i.e. operation in case of a network event or issue. Think in terms of operations' frameworks e.g. ITIL and eTOM.

3- As part of a network's enterprise and information assurance they resort to Server virtualization , federated DBs.
How does the end to end service provision work here ?
