NFV Architecture Explained

NFV – Network Function Virtualization – is an architecture which aims at replacing various hardware network components in the enterprise environment by using managed virtual machines over generic hardware.  This way a single high-performance server can run many of the organizational IT requirements, such as firewall, session border controller, SD WAN and many other functions.

Each such function is called VNF – Virtual Network Function.  Normally in NFV architecture the services, or functions, will be managed remotely by a service provider.  Under NFV architecture it is possible to add or remove services and easily re-distribute resources remotely and without having to add or remove hardware devices.

NFV architecture may also be distributed so that some VNFs will run on premise and some on the cloud or on more than one location.  This is calls distributed NFV.

Benefits of Using NFV Architecture in Enterprise Environment

Using NFV environment lets the organization tap into a wide range of solutions offered by the service provider as VNFs, and pick the relevant ones with minimum risk and no upfront investment.  This way an organization may also make low-cost tests of various solutions before deciding whether or not to use them in their business.

As NFV environment is normally managed by a service provider, the responsibility of making sure all the software is up to date and all security updates are installed on time, it the responsibility of the service provider, which allows the business to focus on their core strengths, rather than on managing their tools.

When working under NFV architecture it makes a lot of sense to also run the organization’s VoIP as VNF.  In such way, the PBX is running as a virtual machine and is controlled by the service provider just as any other VNF.  As modern PBX phone systems are mainly using VoIP and not telephony specific networks as in the past, it is a logical next step to run the organizational phone system as VNF, benefiting from the advantages of NFV flexibility and management tools.
