Sales of software-defined networking (SDN) gear and software might well reach $35 billion by 2018, but sales are likely to be about $3.4 billion in 2014, according to SDN Central.
That illustrates a principle about big changes in communications network architecture: such changes tend to take longer than expected, and that is likely to be the case for some parts of the enterprise or data center SDN and telecom carrier network-function virtualization (NFV) architectures that promise widespread use of open systems and standards-based components.

It’s been an interesting start to the 2014 Winter Olympics in Sochi, Russia – between the #sochiproblems twitter feed reporting everything bad that’s happening, to the too fast downhill which is claiming its share of Olympic athletes and the snowboarders half-pipe that’s melting.
Despite these issues, one thing is clear – technology is making its way into every part of the Olympics. From communications, collaboration and data networking, to security, to information services, to event timing and to analyzing the performance of each athlete – a lot has changed since the last Winter Olympics in 2010.

Timing issues have been a concern of mobile network architects ever since Ethernet – an inherently asynchronous protocol – became important for mobile backhaul. The reasons are obvious enough: without exquisitely maintained timing relationships, user experience degrades or calls terminate because they are not handed over properly from one cell to the next.
These days, it is equally important to maintain Internet access sessions and synchronous services across cells using asynchronous backhaul. Read the full post
In a networked and cloud-based business era, broadband may be the most essential pieces for business continuity and disaster recover. It’s easy to plan for the expected — but disasters rarely follow what is written down on a plan conceived on a sunny weekday between 9 to 5. Let me strongly recommend that you review, verify and sanity check your business continuity plans for 2014. If you don’t find at least one area to change after a full review, you might want to reconsider how valid your review is in the first place.
I write this based upon a recent, ongoing disaster recovery saga taking place at a major organization recently affected by the Polar Vortex of 2014. I can’t be more specific about who is involved or what happened, but I can provide a general outline of events. Read the full post
