Obstfeld writes that Network Function Virtualization (NFV) is the transition of network infrastructure services to run on virtualized computing platform. According to Pate, Software Defined Network (SDN) provides the ability to program the behavior of the network using well-defined interfaces and allow the network devices to be controlled by a central element. The idea for SDN was started when researchers who were experimenting with new protocols found that software in the network devices needed to be changed for each new approach that they wanted to try (2013). The goal of Software-Defined Networking is to enable cloud and network engineers and administrators to respond quickly to changing business requirements via a centralized control console.   SDN encompasses multiple kinds of network technologies designed to make the network more flexible and agile to support  the virtualized server and storage infrastructure of the modern data center and Software defined networking was originally defined an approach to designing, building, and managing networks that separates the network’s control (brains) and forwarding (muscle) planes enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services.
