Network Functions Virtualization

Why Carriers Are Embracing NFV, and What They Should Demand of These New, More Agile Environments

By: Paula Bernier, Executive Editor, TMC

Service providers are undergoing a sea change.

Their networks, which traditionally have been based on turnkey network elements running software on purpose-built hardware, are moving to a software-centric model. In this model the true value lies in the software, while the hardware is typically of the commercial-off-the-shelf variety.

Network Functions Virtualization (NFV) is the name of this new architecture, which not only embraces the model of instituting network functionality in software and running it on industry-servers, but also allows applications and services to leverage those resources whenever and wherever they are.

NFV INSIGHTS: The right SDN is right for NFV

By: Roland Mestric, Director, Video Solutions Marketing

It feels like it was just a few months ago when you could read articles in the trade press lumping together SDN and NFV with NFV being a form of SDN or vice versa.  Yes, both somehow are about virtualization and about converting hardware into software. Today – after numerous proofs-of-concept run by service provides around the globe – we know the role of SDN as virtually indispensable for NFV solutions that aspire to deliver the kind of agility and operational simplification we all expect from NFV. Only SDN can deliver quickly enough the (virtual) networks needed for newly deployed network functions. Alcatel-Lucent has recently demonstrated a complete virtual evolved packet core (vEPC) including a virtual IMS/VoLTE deployed in less than 30 minutes.

NFV INSIGHTS: Making the [business] case for NFV

I still remember with great excitement how, in October 2012, a group of network operators published a whitepaper that coined the term Network Functions Virtualization. This announcement validated a vision that we had been promoting under the name of “Virtual Telco” for more than two years. The telecommunications world had decided to start a fascinating journey towards the cloud, and we were already in the game with a product. What I could not imagine is how fast things would move.

CloudBand Delivers NFV Solution for Network Operators

Mae Kowalke, TMCnet Contributor

As you already know, the cloud is one of the megatrends of our times, and service providers are embracing the open cloud with the help of network functions virtualization (NFV).

An NFV platform enables providers to run network functions on a homogeneous, distributed cloud infrastructure. Using an NFV solution, they can port network functions such as communications and messaging applications and fixed and mobile network functions over to a virtual machine environment. Freed from proprietary, physical hardware, providers can leverage this virtualized infrastructure as the basis for their own service platforms and operations.

Seeing the opportunity inherent in NFV, as described in detail in an applications note Alcatel-Lucent has developed a purpose-built NFV platform for service providers, CloudBand. The platform supports distributed clouds and dynamic network control to meet application demands, and it optimizes network operations by automating cloud node management, application lifecycle management, smart placement and network configuration.
