Network Function Virtualization

Optimize your network for speed and agility

Network Function Virtualization (NFV) is the critical building block for developing a network that can deliver new service instances almost instantly. It introduces the benefits of virtualization into networking infrastructure, allowing you to run network services (such as routing, switching, firewalling, IPS/IDS, VPN, load balancing, etc.) within dynamically provisioned virtual machines (VMs). This separation of network function software from proprietary hardware reduces your CAPEX and if done properly your OPEX spending, as well as lower vendor dependency (lock-in). It not only allows you to achieve faster service instance provisioning but may also make service implementation faster with service modeling using YANG.

In order to achieve these benefits, VMs still need to run on the IT infrastructure, you need a flexible management system for your infrastructure, the (cloud) infrastructure still needs some fundamental networking, and so on. NIL’s understanding of the complexities of networking infrastructure and service interdependence is what makes us the perfect partner to support your successful NFV adoption, as well as other technologies such as SDN and automation, which will improve your network performance and deliver real business value.

Add the benefits of virtualization to your network

Reduced Capex

NFV allows you to achieve the same results with lower hardware expenditure, and helps you adopt the pay-as-you grow model.

Lower Opex

Virtualization doesn’t simply move costs around. It simplifies network management and lowers equipment energy and space requirements.

Faster time-to market

Reduced time to deploy new network functions means that your network can now deliver new services almost instantly, and better support evolving business services.

More flexibility and agility

NFV allows you to scale network services up or down to address changing business demands. Meet the needs of your customers, while optimizing associated costs.

Safer, more reliable, flexible, standardized application platform

The Flex IT platform can host your applications that can form part of your existing closed information system or your e-services opened to the internet. The appropriate service level is specified by means of a Service Level Agreement (SLA). Credibility of processes is demonstrated by the ISO 9001 and ISO 27001 certificates. Flex IT resources are provided by the most advanced, high-performance and reliable IT infrastructure.
