Moving Toward a Virtualized Network—Orchestration, Abstraction, and Programmability
Network functions virtualization (NFV) architectures provide the necessary network flexibility to enable new service delivery models and elastic network scaling to reduce total cost of ownership by leveraging common off-the-shelf (COTS) hardware.
Fundamentally, NFV begins with the shift toward the virtualization of network components currently deployed on purpose-built hardware. As you evolve your networks to NFV, the abstraction of the control-plane and data-forwarding plane simplifies the creation and management of new services. At the same time, you benefit from a programmable network based on industry standard open APIs that give you greater flexibility and agility.
The orchestration of networks, fully virtualized network or a hybrid, lets you dynamically instantiate new services and deliver a network that can provide subscribers with more personalized service as well as an improved quality of experience (QOE).
