Network Virtualization Brings Agility to the Enterprise

Network Virtualization Brings Agility to the Enterprise

Global networks are the central nervous system of companies, impacting all facets of how organizations operate and increasingly, how they deliver value to customers and partners. We’re seeing lots of innovation from communication service providers, equipment makers, cloud vendors and standards bodies. Consider 2015 the year of the corporate network.

Timing couldn’t be better for companies to upgrade their networks and consider new options. The Piper Jaffray 2015 CIO Survey indicates that over 40% of those surveyed plan to upgrade their WANs this year. CIOs cited networking as the area most in need of a refresh, up from 26% in 2014. This marks the third consecutive year networking has increased in the list of IT spending priorities.

Network function virtualization (NFV) is a significant innovation in network design and it comes at an opportune time. Virtualization delivers agility to enterprises in the way they deploy, run, configure, update and adapt their network to meet ever-changing application performance requirements.

Virtualization is transforming the way organizations architect their networks to consolidate many network equipment types onto commodity servers and other network interface devices, which can be located in a variety of customer premises, network nodes and data centers.

Here are three top use cases for network function virtualization already in use today:

Switching Elements

Broadband network gateways, network address translation and routers are being implemented in software and run on commodity hardware in remote and branch offices.

Security and analysis

Deep packet inspection and quality of service measurements can be implemented in software without the need for specialized network appliances. Similarly, firewalls, virus scanners, intrusion detection systems and spam protection will be integrated into network interface devices and managed over the network rather than on site.


Session border controllers and IP multimedia subsystem components are being implemented in software to simplify network deployment and management.

Masergy this week announced Virtual f(n), its virtualized network function platform, which enables enterprises to add routing and firewall capabilities via software, eliminating the need for specialized network appliances and on-site administration.

Masergy’s software delivery model is akin to mobile app stores where consumers can download software to their smartphones, turning them into multifunctional devices to communicate using voice, video and text, enjoy streaming media and monitor home security, to name just a few examples.

Virtual f(n) changes the way networks are architected by removing the management, cost and space requirements typically associated with physical network assets. Through a simple software download, customers can add full-featured network services without equipment shipments and on-site administration. This is the realization of Masergy’s vision of the programmable enterprise.
