Why Network Functions Virtualization (NFV) Calls for a Distributed Network Architecture

By: Paula Bernier, Executive Editor, TMC

There’s no question that the network functions virtualization (NFV) technology around which many telecommunications carriers and vendors are rallying takes a page from the virtualization that already has taken hold in IT data centers. But you can’t judge a book by its cover. NFV and IT virtualization also have their differences.

One key difference is that while data center virtualization tends to rely on a centralized architecture, NFV calls for a distributed one, Andreas Lemke, marketing lead for the CloudBand NFV platform at Alcatel-Lucent, points out in a recent TechZine posting by Andreas Lemke, Marketing Lead, CloudBand NFV platform, Alcatel-Lucent titled, Why distribution is important in NFV.

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.

IP Video: A Whirlwind of Innovation

By: Roland Mestric, Director, Video Solutions Marketing, Alcatel-Lucent

Before the iPhone, the world of TV was relatively simple. Linear TV programs were delivered to the TV set over the air or to its set-top box (STB), which was directly tied to the cable coax, the home gateway or the satellite dish.

Now everything has changed.

Video-enabled, IP-connected devices with ever-greater screen resolution are flooding the market. Tablets, smartphones and smart TVs are running on many flavours of operating systems. All use different protocols, formats and standards. With these devices, end users have many options to watch video. These include being attached to the service provider’s managed network, or being directly connected to the Internet and consuming ‘over-the-top’ content. Moreover, end users want to watch their favorite content on demand; they no longer want to be restricted to linear programing. This adds yet another level of complexity to this whirlwind of change.

Covering all IP video options results in countless protocols, proliferating standards and loads of acronyms. Even industry watchers can find the rapidly evolving world of IP video confusing. That’s why I created this IP video streaming infographic.

Answering the Question of How to Manage NFV Effectively with an vEPC

By: Mae Kowalke, TMCnet Contributor

The advantages to mobile operators of network functions virtualization (NFV) and moving to a virtualized evolved packet core (vEPC) have become clear, and mobile networks operators are pretty much sold on the technology in theory.

As the technology side has been figured out and operators begin to plan commercial deployments of NFV and vEPC, however, discussion is starting to move toward operational requirements and challenges. Mobile network operators need to figure out how best to manage these new virtual network functions (VNFs) and the NFV infrastructure, and also how to modify the existing network operations model when these VNFs are deployed.

NFV INSIGHTS: Is OpenStack ready for NFV?

By Andreas Lemke, Ph.D. - Alcatel-Lucent

Open source has had a massive impact on information technology and the web: The Linux operating system, the LAMP stack, browsers, the Android smartphone OS. Individual enthusiasts, universities, and businesses spend enormous resources to build technologies, and then give them away for free. Are they out of their mind? The success of open source shows they are not. 

OpenStack, the open source cloud management software, has come into the focus of service providers as a rapidly advancing, cost-effective technology foundation for NFV. With OpenStack, service providers are expecting to escape the tangles of individual vendors and build an open horizontal platform for their future networks.

Benefits of Standardization in the Internet of Things

By: Tim Carey, Industry Standards Manager of Alcatel-Lucent’s Customer Experience Division

The world of M2M is changing as solutions move from single purpose devices that transmit data to and receive commands from an application in the network to an Internet of Things where solutions permit devices to be multi-purpose and applications to be collaborative.

The Internet of Things can benefit from global standardization efforts that:

  • Enable deployment of standards compliant devices and applications with no or minimal customization thereby expanding the applicable device ecosystem and reducing deployment time
  • Provide an ecosystem that readily allow applications to share information and experiences
  • Provide an environment where communication occurs securely and the privacy and confidentiality of the user is maintained

Successful Communications Services Have Six Features in Common

By: Mae Kowalke, TMCnet Contributor

Large enterprises increasingly resemble public network service providers as they manage access, transport and network routing while controlling devices and sessions. Whether businesses build their own or buy their communications services through a public provider, the IP communications architectures are looking remarkably similar.

“I’ve noticed that both private service operators (CIOs of large enterprises) and public service providers are implementing very similar solutions around the globe,” wrote Oliver Krahn in a recent TechZine article, 6 Steps that Improve Communications Services.

Cloud DVR Comes of Age

By: Mathew Pitt-Bailey, Product Communications, Alcatel-Lucent 

I know what you’re thinking. Here is another article about “the cloud”. There’s been a lot of talk, a lot of promise – in short, a lot of hype about how the cloud will transform our industry. But when is it going to start delivering? 

Well actually, it already has.
