 which virtual networks are built. The NFV leverages the economies of scale of the IT industry. The NVFI is based on widely available and low-cost, standardized computing components. The NFVI works with different types of servers, for example, virtual or bare metal, software, hypervisors, VMs, and VIMs in order to create a platform for VNFs to run. The NFVI standards help increase the interoperability of the components of the VNFs and enable multivendor environments [42-44]. The NFV architecture comprises major components including VNFs, NFV-MANO, and NFVI that work with traditional network components like OSS/BSS. The NFVI further con- sists of NFVI points-of-presence (NFVI-PoPs¹4 which are the sites at which the VNFs are deployed by the network operator, including resources for computation, storage, and net- working. NFVI networks interconnect the computing and storage resources contained in an NFVI-PoP. This may include specific switching and routing devices to allow external con- nectivity. The NFVI works directly with VNFs and VIMs and in concert with the NFV orchestrator (NFVO). NFV services are instantiated and instructed by the NFVO, which uti- lizes VIMs that manage the resources from the underlying infrastructure. The NFVI is Network function virtualization infrastructure points-of-presence is a single geographic location where a number of network function virtualization infrastructure nodes are situated. 5G Network Architecture critical to realizing the business benefits outlined by the NFV architecture. It delivers the actual physical resources and corresponding software on which VNFs can be deployed. NFVI creates a virtualization layer on top of the hardware and abstracts the hardware resources, SO they can be logically partitioned and allocated to the VNF in order to perform their functions. NFVI is also critical to building more complex networks without geographi- cal limitations of traditional network architectures. A network service can be viewed architecturally as a forwarding graph of NFs inter
