Network Virtualization solutions

NVS is used to deploy Network Functions Virtualization (NFV) to create cloud-based applications with a combination of virtualization software and industry standard hardware.
Global operators are increasingly looking at using NFV software and industry-standard hardware to deploy enterprise applications rather than using integrated, proprietary hardware and software systems. Enterprise applications that can be deployed with NFV software include virtual firewalls, IP–VPNs, load balancing, application acceleration, Wide Area Network (WAN) connectivity and optimization services, and network services using virtual customer premises equipment (CPE).



NFV also is flexible, cost-effective, scalable, and secure. With these benefits, NFV addresses several trends shaping service provider networks.

  • Flexibility: Operators looking to quickly deploy new services require a much more flexible and adaptable network -- one that can be easily and quickly installed and provisioned.
  • Cost: Cost is a top consideration for any operator or service provider these days, even more so now that they see Google and others deploying massive datacenters using off-the-shelf merchant silicon (commoditized hardware) as a way to drive down cost. Cost is also reflected in opex -- how easy it is to deploy and maintain services in the network.
  • Scalability: To adapt quickly to users' changing needs and provide new services, operators must be able to scale their network architecture across multiple servers, rather than being limited by what a single box can do.
  • Security: Security has been, and continues to be, a major challenge in networking. Operators want to be able to provision and manage the network while allowing their customers to run their own virtual space and firewall securely within the network.
