Changes such as NFV won't allow telecom to sacrifice fundamentals such as high availability. But NFV does give us an opportunity to rethink some principles of the network, starting

Orchestration can be the key to reconciling a carrier's legacy OSS/BSS platforms with newer NFV deployments. However, the needs of development and test organizations call for a particular type

Whether it’s Domain 2.0 or a new enterprise SDN, large network projects face many impediments to success. Here's what AT&T's former CTO suggests you do about it.

Pay-per-use models aren't practical for many mobile operators due to the operational complexity involved. Here's how a service-aware network using SDN and NFV could help.

A peek inside the structure of NFV shows that it's primed to be deployed quickly by carriers. That's partly due to ETSI's guidance, but also due to the fact

With the advent of network functions virtualization (NFV), let's step back and remember that carrier-grade networking is a daunting task, one that goes beyond the tenet of high availability.

David Meyer clues us in on the lessons learned from a year elbow-deep in open-source. Code is the coin of the realm, as they say, but sustainable value comes

Plans for connected-vehicle technology bear more than a little resemblance to what the networking industry has been doing with SDN and, especially, NFV. Maybe it's time to start talking

NFV is gaining significant momentum in the industry. In response, the NFV ISG has set an aggressive timescale to release the initial set of technical documents approving the future

This is the year for carrier SDN and NFV to kick into gear, so how are we doing? A look at virtual networking, network overlays, management & orchestration, and

The Internet of Things is all fun and games until your refrigerator turns into a spambot. NFV has a role to play in handling security as our homes' connected-device

In 2014, we can expect more production deployments of SDN, and that's going to force us to consider some key questions. Should the northbound interface be standardized, and how?

Eric Carmès, CEO of 6WIND, addresses the recent ETSI approval of the CloudNFV Proof-of-Concept (PoC) application submitted by the CloudNFV™ initiative. The CloudNFV architecture provides end-to-end NFV implementation and

A few examples of NFV applications show why the technology is getting traction with both service providers and OEMs, considering the variety of potential benefits the technology could unlock

2014 Predictions on SDN and NFV by Kelly Herrell

NFV Said to SDN: 'I’ll Be There for You'

NFV sprang up quickly, but industry-changing innovation does not happen overnight. Even for a carrier that wants NFV for one specific service, it's worth investing in a full platform

The difference between network functions virtualization (NFV) and network virtualization is causing some confusion, and meanwhile, the industry is still feeling out just what 'SDN' is going to mean.

Detailed, real-time understanding of traffic can be a boon to SDN, which is why network operators can benefit from having deep packet inspection integrated into the virtual switch. The

October has been a thicket of conferences related to SDN and NFV. In this latest NFV blog post, Marc Cohn looks at how operators' thinking around NFV has changed

Where is ATCA's place in an NFV world? The platform-level standard for telecom hardware is not made obsolete by NFV's use of standard chips; in fact, ATCA still has

What are the network requirements to support NFV? The ETSI group defining NFV set that question aside at first, but some clear patterns are emerging in terms of service-provider

What's going on inside the ETSI NFV group, and who are these guys, anyway? In this first of a series of posts about NFV, Marc Cohn discusses the group's
