The rise of the new virtual reality: Network Functions Virtualization

With a rise in the usage of storage data centers and increasing complexities to manage data crossing across the network, it becomes apparent that many companies face a daunting challenge to thrive in the digital era. Hence, large, medium or small enterprises need to transform/build their network by adopting NFV (Network functions virtualization).

Network functions virtualization as the name suggests abstract physical networking components into software applications via virtualization technology. It promises cost-efficient transition on the software platform to break the vendor lock-in problem as well as reduces power consumption and equipment cost. NFV is widely known as the game changer in the telecom industry over the past years.

With numerous benefits NFV enables the transformational journey in response to the sky-rocketing network demand. Many companies are embracing NFV to enable agility, speed as well as creating the ability to deliver services at an unprecedented rate. Compared with other server virtualizations, NFV is growing at an annual rate of 32%. It acts as an innovative foundation for the companies to compete effectively as well as allows them to become service-oriented and client-centric.

Benefits of NFV

  • Rapid service delivery
  • Hardware Flexibility
  • Cost efficient
  • Automated & Operational efficiency
  • Agility
  • Scalablity & Elasticity
  • Easy Validation

Standard IT network functions virtualization combined with software-defined networking can help the telecom service providers overcome the constraints of hardware based appliances while attempting to accelerate the deployment of new network services to support their revenue and growth objectives.

It involves implementing network functions in software that can run on a range of industry standard server hardware, and that can be moved to, or instantiated in various locations in the network as required, without the need to install new equipment. NFV is inherently automation friendly and can help organizations decentralize tasks associated with running the business such as inventory management as well as the procurement process.

NFV in combination with SDN technologies are being used to build a secure “demilitarized zone” inside the data centre. This means now every virtual machine inside a data centre has its own virtual firewall, in addition to the physical firewalls that defend the perimeter. NFV is the key in the telecom sector, unleashing services that run on networks like network routing, content delivery networks, load balancing, as well as the security functionality making it more agile and robust.

The 4 pillars of NFV

Virtualization Abstraction Programmability Orchestration
High-performance standard servers for carrier applications Service and network abstraction Data control & management planes Multi-service eco-system, policy driven flows
Comprehensive hypervisor support On-demand resourcing Open and developer-friendly APIs Policy-driven flows and steering
