Hello,
Hello Dear!
The NFV uses IT virtualization technologies to consolidate many network equipment types onto industrial standards, such as servers, switches, and storage, which could be located in data centers, network nodes, and in end user premises. It involves the implementation of network functions in software that can run on a range of industrial standard servers. In addition, and that can be moved to, instantiated in, or deployed at various locations on the network as required, without the need of installing new equipment. NFV implements network functions in the form of software and can be applied to a series of standard physical hardware. Physical hardware provides different network functions with required resources by means of the virtualization technology.
So the NFV can improve the network flexibility
Thanks
