What Is Network Function Virtualization (NFV)?

Network Function Virtualization (NFV) is a network architecture concept that leverages standard IT virtualization technologies to consolidate and deliver network functions as soctrophare instacans. Instad of buying a dedicated physional firewall, a telecom operator can now deploy a Virtualization Network Function (VNF) for firewalling on a commercional off- the- shelf (COTS) server. Thee Europeun communications Standards Institute (ETSI) has incorven thing of NFV, definition three triwe thre primarents:
