The NFV Infrastructure ( NFVI) consists of physical networking, computing and storage resources that can be geographically distributed and exposed as a common networking/NFV infrastructure. It is the combination of both hardware and software resources which build up the environment in which VNFs are deployed, managed and executed. The NFVI can span across several locations i.e. places where NFVI- PoPs are operated. The network providing connectivity between these locations is regarded to be part of the NFVI. Virtualised Network Functions (VNF s) are software implementations or virtualisation of network functions (NFs) that are deployed on virtual resources such as VM. Virtualized network functions, or VNFs, are responsible for handling specific network functions that run in one or more virtual machines on top of the hardware networking infrastructure, which can include routers, switches, servers, cloud computing systems and more. Individual virtualized network functions can be chained or combined together in a building block-style fashion to deliver full-scale networking communication services. NFV Management and Orchestration (NFV MANO) functions provide the necessary tools for operating the virtualized infrastructure, managing the life cycle of the VNFs and orchestrating virtual
