On Network Virtualization and SDN
Scott Lowe
APRIL 30, 2013
Is there a difference between network virtualization and Software-Defined Networking (SDN)? So, in a similar fashion to my post on network overlays vs. network virtualization , I thought I’d weigh in with some thoughts. With this definition in hand, let’s compare network virtualization to SDN.
