Software Defined Networking And Virtualization. Both use software to recreate key components of networking infrastructure. SDN seeks to separate network control functions from network forwarding functions while NFV seeks to abstract network forwarding and other networking functions from the hardware on which it runs.
At the risk of using an old metaphor its like a new car. Trends in SDNNFV security are outlined. While network virtualization allows organizations to segment different virtual networks within a single physical network or to connect devices on different physical networks to create a single virtual network software-defined networking enables a new way of controlling the routing of data packets through a centralized server.

Software Defined Network passes elasticity computerizations and customizations to the broadband networks. While network virtualization allows organizations to segment different virtual networks within a single physical network or to connect devices on different physical networks to create a single virtual network software-defined networking enables a new way of controlling the routing of data packets through a centralized server. SDN centralizes management by abstracting the control plane from the data forwarding function in the discrete networking devices.
