Summary And Discussion Points SDN/NFV is a strategic technology transformation Its not about virtualizing a VNF on a bunch of servers Its about hosting VNFs on a Open, Programmable, Intelligent Network Infrastructure with flexibility to Manage and Automate Services Raising key questions: How does SDN/NFV add to economic and strategic value to your business? How much of automation of Physical & Virtual services has been achieved? Leading to high Operational disruption How do you plan to manage the complex cost of transition effectively?
