Domain 2.0, Domains, and Vendor SDN/NFV
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…

Public Internet Policy and the NGN
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…

What’s Involved in Creating “Service Agility?”
“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…

Is Ciena’s Agility Matrix Agile Enough?
NFV, as I’ve said before in blogs, is a combination of three things—the MANO platform that orchestrates and runs services, the NFV Infrastructure on which stuff is run/hosted, and the VNFs that provide the functionality. You need all of them to have “NFV” and it’s not always clear just where any of them will come…

OSI Layers, Policy Control, Orchestration, and NGN
If you look at any model of network evolution, including the one I presented for 2020 yesterday in my blog, you find that it involves a shifting of roles between the familiar layers of the OSI model, perhaps even the elimination of certain layers. That begs the question of how these new layers would cooperate…

Is There a Radical Shift in Networking on Tap?
In 2020, what will “the network” or “the Internet” look like, in terms of infrastructure? I’ve gotten that question a lot lately, as well as the question of whether it’s SDN or NFV or the cloud, or mobility or maybe content or even Cisco, that’s driving the evolution. Of course, people also wonder who will…

What the Heck is “Carrier Grade?”
One of the interesting issues that I encountered at the HP Discover 2014 event this week was that of “carrier grade”, and I even had someone make a related comment on a prior blog of mine. For ages, people have talked about how important it was to be “carrier grade” and offer “five-nines” reliability. NFV…

A Deeper Dive into HP’s OpenNFV
I’ve blogged before about HP’s OpenNFV strategy, important IMHO because it’s not only from perhaps the most inherently credible of all possible NFV sources but also the functionally most complete—at least in terms of planned features. I’ve attended the HP Discover 2014 event in Barcelona this week, spoken to all the key HP NFV people,…

NFV: Where Do I Start?
I blogged a year ago that optimum implementation of NFV could create between 80,000 and 130,000 new data centers, making NFV potentially the largest source of new server and data center component installations. There is little doubt that NFV could touch every aspect of virtually every service, so there’s lots of reasons for operators to…
