Network Functions Virtualisation (NFV)

Network Functions Virtualisation (NFV) liberates network functions – firewalls, intrusion detection, load balancing, NAT, DNS, caching, SIP gateway, etc. – from proprietary hardware, allowing them to run as virtual appliances in software.

What does the traditional network infrastructure look like?

A traditional network infrastructure features a wide range of proprietary hardware with each piece of hardware typically dedicated to performing single individual functions. In this environment, turning up new applications or services, or even reconfiguring the network, means introducing even more proprietary hardware, which takes up more equipment room space, uses more power and adds to the workload of your networking specialists.

A more agile and flexible network

NFV uses standard IT virtualisation technologies that run on high-volume service, switch and storage hardware to virtualise network functions. By virtualising these functions, the network becomes more agile and flexible, and can respond quicker and more intelligently to the needs of applications and services running on it.

Key benefits of NFV

  • Free network functions from proprietary hardware
  • Reduce CAPEX by running network functions on off-the-shelf platforms on a single hardware platform
  • Easily and quickly deploy new applications and scale up/down new services
  • Reduce the risk of trialling and deploying new applications or services
  • Improve network automation, agility and flexibility
