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.

Verplanke believes that DPDK (Data Plane Development Kit) and virtualization are key to virtualizing workloads that move around lots and lots of packets, such as firewalls, routers, and other similar functions. Next, he discusses the evolution of network devices so far. First, DPDK provides optimized pass-through support.
