The year 2014 will go down as the “Year of the Hack.” What projects will help keep 2015 from being “The Year of the Hack, Part 2?”

When we speak with network operators, we hear angst. What does this mean for 2015? Here’s our 2015 SDN Predictions to reduce the angst.

Unless we take a concrete step to clarify the term “open” it is at risk of becoming another cliché. Creating a commonly understood context and taxonomy can help us

Neela Jacques of the OpenDaylight Project explains why community is critical for an open-source project and what common threads successful projects share.

In the WAN, where the optical transport network plays a key role, SDN is now beginning to emerge as a new technology tool that offers the promise of managing

Public cloud providers excel at creating standardized virtualized instances, but this isn’t always ideal for the consumer who needs a variety of custom options.

SDN will only be disruptive if it displaces commercial switches and routers with purpose-built hardware that has total control over packet forwarding.

If there is a technology moving as quickly as SDN, it has to be photonics. SDN coupled with optical switching at Layer 1 allows the physical network to be

Here's an overview on validating OpenStack Neutron network module and plugins.

EVO, OpenStack, more NSX — that's all fine, but where were VMworld's truly groundbreaking, mind-blowing announcements? Maybe it's a case of 'Wait 'til next year.'

What are the landmark deals in the SDN game so far? Check out analyst Scott Raynovich's list and see what he expects next from the M&A machine.

Ethernet speed transitions have garnered close attention from networking industry vendors, consumers and analysts, as they trigger new technology buying cycles & periods of rapid change in the Ethernet

Carriers have dealt with metro environments for years. The objective being to pull traffic in, and then make distributed resources accessible via some distribution or transport layer. While this

A Software-defined networking market transition enables unprecedented value from our networks. Read more about the SDN market and an open, evolutionary approach that is required.

This article is about Facebook and the Wedge, startups forging deals combining SDN with powerful commodity hardware and the SDN world joining next-generation infrastructure.

While traditional vendors rush to show the world how they can support virtualized functions tuned to their way of doing business, it is unlikely that all vendors will survive

SDN for transport networks — Layer 0 and Layer 1 —is easy to talk about, but real-life 100G and ROADM networks have a lot of complexity to consider. Finding

SDN and NFV can pave the way to heavier automation and a software-defined infrastructure. But that road is full of obstacles related to visibility, security, and the language used

Online shopping platform Wanelo brings together more than 10 million registered users and 200,000 stores. After Wanelo moved to the cloud, it needed a way to manage configuration —

While it's clearly not a conceptual requirement to implement SDN and NFV together, the technologies complement one another and work well together in supporting a software-defined data center.

SDN really can help a telco go green. When we talk about managing the carbon footprint and keeping energy costs low — for example, in the diesel-fueled mobile networks

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

A DevOps methodology can result in a more resilient development environment. The testing of network changes, for example, could be moved away from a brute-force routine to something more

New traffic patterns from the likes of Netflix are causing lots of hairpinning and 'hot potato' traffic handoffs, all of which consume expensive PE router ports. Here's how ISPs
