Network Functions Virtualization

Video Shows How Network Functions Virtualization (NFV) Actually Works

By: Mae Kowalke, TMCnet Contributor

Rarely does a video about network functions virtualization (NFV) captivate your attention like the one that Alcatel-Lucent recently uploaded about service innovation and lean operations in the context of NFV. Sometimes NFV can be a challenging concept to get your head around, but the video breaks it down with clear visuals and none of the PowerPoint that usually puts you to sleep.

If you haven’t seen the video you can watch the embedded version below. But also let me explain what the video is talking about.

vEPC in LTE networks: Time to move ahead

By: Keith Allan, Director IP Mobile Core Product Strategy, Alcatel-Lucent

From original TechZine article

Can the virtualized evolved packet core (vEPC) be deployed today in large scale, LTE networks?  Mobile network operators (MNOs) are increasingly convinced that the vEPC has become viable both financially and technically. And I think so, too, based upon the advances made over the past year that I’ll discuss in this blog.

NFV INSIGHTS: Preparing for the future of NFV

Have you ever gotten your hands dirty and really implemented an NFV or SDN application? Six teams from academia and industry in Israel and Europe can answer with a resounding yes! These teams gathered in Haifa at the 4-day 2015 Winter School and Hackathon event, organized by Bell Labs, Alcatel-Lucent’s CloudBand team and Israel’s leading Institute of Technology, Technion. The event offered a full program to get acquainted with the fundamental concepts behind cloud computing, software defined networking (SDN) and network functions virtualization (NFV).

Can the vEPC be deployed in the LTE consumer network?

By: Keith Allan, Director IP Mobile Core Product Strategy, Alcatel-Lucent

This article discusses the progress in the development and operational management of the vEPC to support the LTE consumer network. It answers the question: Is the vEPC commercially viable in large-scale, LTE network deployments? At Mobile World Congress 2015, Alcatel-Lucent will show a live demonstration of vEPC dynamic scaling together with simplified NFV management and orchestration.

Over the past several years, I’ve met with many mobile network operators (MNOs) and discussed their plans for virtualizing the evolved packet core (EPC). It’s clear from the more recent conversations that MNOs are now convinced that the vEPC is both financially and technically viable for their networks.  But is the vEPC ready for the MNO’s LTE consumer network?  In this article, I’ll discuss why I now think that’s possible.

Customer Self-Care is Win-Win for CSPs and Users

By: Mae Kowalke, TMC Contributor

Self-service to one degree or another has been present since the rise of the web. However, customers are increasingly choosing self-service because they feel more empowered and it is often perceived to be an easier interaction than dealing with a live person. The rise of the smartphone also has increased the use of self-service.

In fact, as explained by Jessica Verbruggen, Integrated Marketing Assistant at Alcatel-Lucent Motive, in a recent TechZine article, Empowering Autonomous Customer Self-Care, self-service can be a win-win for customers and communications service providers (CSPs).

Partnering is Key to Successful Network Transformations

By: Peter Bernstein, TMCnet Senior Editor

One of the things that will characterize 2015 is the trend that started picking up momentum in 2014 that operators of physical communications networks have developed a sense of urgency about transforming their networks.  It used to be that if you were a network operator you could invest with some level of assurance that the hardware and the associated software to run it would be core to your network for possible decades before becoming obsolete.  However, as everyone in the industry knows, this is no longer the case.

As the world becomes more software-centric in terms of service creation, delivery, agility, security and performance— to meet the tsunami of data heading operator’s way and to allow network operators to maintain their relevance as ecosystem hubs rather than “dumb pipe” providers—cost efficient and effective operational excellence and the need to be fast-to-market and fast in the market with innovative services and enhanced customer experiences have become paramount. It is why so much attention is being paid to thing like Software-Defined Networks (SDN) and Network Functions Virtualization (VFV). 

The need for speed has become (pardon the turn of phrase) hyper-critical.  However, with recognition of the need to transform and do so rapidly should also come the recognition that network operators cannot transform rapidly and successfully on their own...

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

By: Joaquin De La Vega Gonzalez-Sicilia, Alcatel-Lucent Sr. Manager, Cloud Consulting Services

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.
