Advanced network technologies, such as Software Defined Network (SDN) and Network Function Virtualization (NFV), dynamically modify speed and bandwidth to enhance performance. Network intelligence helps enterprises provide customized service for diverse customer segments.

Network function virtualization (NFV) is a network architecture concept that uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create communication services.

Network Function Virtualization can be summed up by the statement that: "Due to recent network focused advancements in PC hardware, Any service able to be delivered on proprietary, application specific hardware should be able to be done on a virtual machine". Essentially: Routers, Firewalls, Load Balancers and other network devices all running virtualized on commodity hardware
