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

Small projects that get big can quickly get out of hand. Here's one coder's experience in fixing that problem by using a message bus and, in the process, developing

One case study suggests how an overlay SDN model can be a key part of a hybrid cloud model, helping an enterprise adopt public clouds without having to migrate

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

Network programmability is the key to SDN and a means of unleashing the network's power to create a faster, more flexible, intelligent infrastructure. By optimizing network resources, dynamic programs

This year more than last, in cloudy neighborhoods everywhere, SDN costumes are sure to be the most popular. Everyone wants to be SDN this year. Underneath the unicorn horn

Yes, SDN can help the broadband network, too. It's a matter of measuring consumption in real-time by taking telemetry data and exerting policy control on the fly — things

SRI International's Phil Porras unveils new groundbreaking SDN security research and tools, led by SE-Floodlight, which is a distributed reference implementation of a security-enhanced SDN controller. It's part of

In the last few months, space has been filling up from people jumping on the "white box, bare metal switch" bandwagon. For example, GigaOm recently discussed Facebook’s initiative in

SDN has a place in optical transport. With recent advances turning the optical core into more of a switched and meshed architecture, it's time to start dynamically provisioning the

Stop being afraid of OpenDaylight, Brent Salisbury says in this rebuttal to the opinions in "Ubuntu Has a Challenge for OpenDaylight." His experience has convinced him that open-source meritocracy

While there is no magic solution to fix capacity problems, mobile carriers can use SDN to alleviate the stress on their networks and to make the Internet of Things

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

SDN's success rides not on arguments about OpenFlow or OVSDB, but on what it can do for applications. It's going to be about giving DevOps teams the automation, visibility,

Watch out for VM sprawl under SDN, because that's what could happen if too many resources want the same things. There's also a danger of watching compute requests spiral

Network monitoring typically takes but cannot give — it reads data from the network, but can't instruct the network on how to improve, at least not in any timely

Answering his own question from 18 months ago, contributor David Lenrow looks at where the SDN controller has gone and is going, now that OpenDaylight and open-source development are

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

Sharon Barkai of startup ConteXtream found a good amount of SDN information being presented at Sigcomm recently. He gives a rundown of talks that covered fault tolerance, elastic controllers,

Your favorite load-balancing algorithms might lose their effectiveness as more workloads move to the cloud. A smarter take on traffic management is in order.

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

The NSX announcement for software-defined networking (SDN) sure got a lot of attention, but is the product all that necessary?
