“The times they are a’changing”, as the song goes. The pace and direction of the changes could be influenced by vendors agile and determined enough to get out there and take some bold steps. We’ve looked at the IT giants who have the most to gain from a transition to a software-server vision of networking. …
Next year is going to be pivotal in telecom, because it’s almost surely going to set the stage for the first real evolution of network infrastructure we’ve had since IP convergence twenty years ago. We’re moving to the “next-generation network” everyone has talked about, but with two differences. First, this is for real, not just…
Over the past several months, I’ve talked about the evolution in networking (some say “revolution” but industries with 10-year capital cycles don’t have those). Along the way I’ve mentioned vendors who are favored or disadvantaged for various reasons, and opened issues that could help or hurt various players. Now, I propose to use the last…
One of the questions being asked by both network operators and larger enterprises is how SDN can play a role in their future WAN. In some sense, though it’s an obvious question, it’s the wrong one. The broad issue is how virtualization can play; SDN is one option within that larger question. If you look…
Since I’ve blogged recently about the progress (or lack of it!) from proof-of-concept to field trials for SDN and NFV, I’ve gotten some emails from you on just what a “field trial” is about. I took a look at operator project practices in 2013 as a part of my survey, and there was some interesting…
Since I blogged recently on the challenges operators faced in making a business case for NFV, I’ve gotten quite a few emails from operators themselves. None disagreed with my major point—the current trial and PoC activity aren’t building a business case for deployment—but they did offer some additional color, some positive and some negative, on…

Last week we had some interesting news on AT&T’s Domain 2.0 program and some announcements in the SDN and NFV space. As is often the case, there’s an interesting juxtaposition between these events that sheds some light on the evolution of the next-gen network. In particular, it raises the question of whether either operators or…
The FCC is now considering a new position on Net Neutrality, and also a new way of classifying multi-channel video programming distributors (MVPDs) that would allow streaming providers who offered “linear” (continuous distribution, similar to channelized RF) programming as opposed to on demand to be MVPDs. That would enable them to negotiate for licensing deals…
“Service agility” or “service velocity” are terms we see more and more every day. NFV, SDN, and the cloud all rely to a degree—even an increasing degree—on this concept as a primary benefit driver. There is certainly a reason to believe that in the most general case, service agility is very powerful. The question is…
