The main
objective of NFV is to move network functions from dedicated hardware
appliances to software running on commodity servers, storage devices, and
switches, using standard IT virtualization technologies.
The main benefits of NFV are increased flexibility,
scalability, and cost-effectiveness in network infrastructure. With NFV,
network functions can be dynamically provisioned, scaled up or down, and
migrated across different physical servers and data centers. This enables
network operators to respond more quickly to changing traffic patterns and
service demands, without the need for manual configuration and hardware
upgrades.
NFV is often used in conjunction with Software-Defined Networking (SDN) for transmission, which provides a centralized control plane for managing network traffic flows and policies. Together, NFV and SDN can help network operators create more agile, efficient, and scalable networks that can adapt to the changing needs of modern applications and services intelligently.
