VNF
Virtualized Network Function

Within an NFV (Network Functions Virtualization) framework, the VNF is the term given to a network node that has been implemented as a software process. An example could be an MME (Mobility Management Entity), where traditionally this would be a physical device but after virtualization, it would run as a software based VNF. All VNFs in the system will share compute, storage and networking resources through interaction with the NFVI (NFV Infrastructure).
