Data security has become the key concern of businesses everywhere. Following last year’s high-profile breaches and the damage to reputation and revenue caused by the fallout, enterprises across the world are waking up to the fact that their networks are fundamentally insecure. For IT operators in all major organizations, protecting the integrity of their network is now the most significant challenge. They know that attacks can come from any direction, including from cyber criminals and secret service organizations who may be hacking into portals to steal data or simply eavesdropping on data sent over WANs to collect information such as unencrypted passwords. The other growing trend is to finally focus on protecting data as it moves outside the walls of organizations and data centers ...

Today the network operator industry descends on San Diego for NANOG 66. Carriers, vendors and other industry players will convene to share insights with one another on how to run a massive global IP network, as well as get a much needed shot of Vitamin D from some early Spring California sunshine. Standing here at NANOG reminds me of the last time I was in America’s Finest City when I got to pay another visit to San Diego’s world-renowned zoo. I’m sure that carriers and business customers attending the conference looking for DCI solutions will find it’s every bit as noisy and colourful as a wildlife exhibit ...

As always, PTC in Hawaii was a great event to kick off the year. It looks like 2016 will be a crucial time for software-defined networking (SDN) and network functions virtualization (NFV) and this was reflected in the program for PTC'16. There were three SDN/NFV-focused sessions (compared with only one last year), including the panel discussion that I took part in. It turned out to be a fascinating and very lively roundtable debate chaired by Joe Weinman, author of Cloudonomics and Digital Disciplines. Along with panellists from Ciena and BTI Systems, I discussed the implications of SDN/NFV for cloud and network service providers. Here’s a few of the main points I took from our debate ...

For many years, network engineers had a dream. Their vision was that one day a network's operations and management would be driven by its applications. Today, with software-defined networking (SDN), that dream is finally becoming reality. ADVA Optical Networking recently played a key role in a major European multi-layer multi-vendor SDN field trial that was proof of this. The demonstration highlighted some of the key achievements of the past few months. As well as use cases like traffic optimization and multi-layer re-routing following cable breaks, the most significant breakthrough was the utilization of an SDN architecture in real-world production networks. Juniper Networks and ADVA Optical Networking had already demonstrated packet optical multi-layer coordination at SDN OpenFlow World Congress in Düsseldorf, Germany in October 2015. In that showcase ...

Did I blink too quickly or was CES2016 over in a flash? In some respects, the event lacked the wow factor of previous years, although there were some emerging technologies that did catch my attention. In particular, Virtual Reality (VR) which has suitably matured to become an increasingly convincing proposition for gaming and broadcasting alike. Social VR – the New Buzzword for 2016: Oculus Rift has been the focus of a number of new developments in both the gaming and interactive broadcasting sectors and at CES2016 HTC were keen to jump onto the VR bandwagon with their impressively slick Vive headset that plans to give Oculus a run for its money. "When we first announced Vive ten months ago we had an ambitious goal of fundamentally changing the way people communicate and interact with the world – forever," commented Cher Wang, chairwoman and CEO of HTC. "Since then...
