Network Functions Virtualization NFV abstracts network functions, allowing them to be installed, controlled, and manipulated by software running on standardized compute nodes. NFV incorporates cloud and virtualization technologies to drive rapid development of new network services with elastic scale and automation.

The desire to automate the orchestration and management of network, storage, and compute resources is a key driver of development for NFV and SDN. Imagine a scenario that includes one physical server with 10 VMs or hundreds of containers.

This concept would never scale if manual operations were required. With automation, you can rapidly spin up or destroy virtualized network functions VNFs such as VMs, containers, routers, firewalls, and intrusion prevention systems IPS , to elastically scale your network functions to match dynamic demand. NFV brings agility in delivering network services with capital efficiency by removing bottlenecks imposed by manual processes, and allowing new services to be deployed on demand.

The modular architecture of NFV is what allows service providers to automate at every level. Major components of the architecture include:. The individual functions that become virtualized in software implementations, such as firewalls, routers, route reflectors, and broadband network gateways BNGs , are called virtual network functions VNFs.

Unlike networking platforms that are built upon service-specific hardware, NFV supports a software infrastructure that is independent of the hardware. Commercial off-the-shelf COTS x86 server hardware acts as a common compute platform for the virtual machines VMs that deliver the network functions. Server compute, memory, and storage resources can be flexibly shared by multiple VMs simultaneously to tailor performance and scale for each service while optimizing costs.

Unlike dedicated hardware platforms that support a single service and are amortized over time, NFV supports the agility to scale-out and scale-in to match service demand while hosting multiple services on a single physical server to achieve economic efficiencies. A VNF can be implemented as a single VM on a single server or it can be disaggregated and implemented as multiple VMs across multiple servers. As a service, a VNF may be implemented using multiple applications, each run within its own VM, to tune the performance and scale of that application without the need to instantiate an entirely new VNF.

Based upon the ETSI NFV reference architecture, hardware resources like compute, storage, and networking are abstracted using a virtualization layer called a hypervisor. The hypervisor creates and runs VMs that share the underlying hardware.

Networking of the VMs and services is the responsibility of a software-defined networking SDN controller, which automates subnet membership and policy enforcement.

Major components of the architecture include: NFV infrastructure NFVI building block—Provides the virtualization layer hypervisors or container management systems such as Kubernetes , and the physical compute, storage, and networking components that host the VNFs.

OpenStack is an example of an open source VIM, controlling the physical and virtual resources. VNFs—Software-based applications that provide one or more network services. Network Function Virtualization NFV is a concept in which network functions traditionally performed by dedicated hardware devices are performed by software that runs on virtual machines in various network locations. The virtual machines run software that performs traditional functions like routing, firewall, or network address translation NAT.

These functions are known as virtual network functions VNFs. In Figure 1 the upper part of the diagram shows conventional physical network devices chained together to provide network services.
