One theory about SDN is that it will give rise to a wave of white boxes, or bare metal switches. But given the number of unknown factors still floating

SDN overlays are necessary because networks were static back when IP networking was established. Now, applications can move, and overlays can help the network cope — but overlays come

Yes VXLAN does need testing, even though it's 'only' a Layer 2/3 technology. The benefits of VXLAN can be realized more quickly by testing often, with realistic application traffic,

In optical transport, smaller DWDM equipment vendors could move toward SDN more aggressively than larger suppliers, because the latter might be eager to preserve their heavy investments in MPLS

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

The metro is seeing tremendous traffic growth; cloud, content and service providers need visibility into apps; and the cost/revenue curves in today’s networks stink. Given those factors, how can

2014 Predictions on SDN and NFV by Kelly Herrell

With recent movements by Juniper's OpenContrail and ON.LAB's ONOS in the last few months, it looks like 2014 might be the year where controllers duke it out for dominance.

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

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

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

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

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

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

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

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

Optical networking can help scale a data center, but the optical part faces scaling challenges of its own. UC San Diego has been working on that by taking a
