We all think that networking is changing, and most probably agree that 1) the cloud is the primary driver, and 2) SDN is the term we use to describe the new “connection architecture”. I think that the point-three here is that NFV is the cloud-platform architecture that will describe how the hosted network elements are…
I’ve noted in past blogs that the world of SDN is evolving, and perhaps the most significant element of this evolution is the emergence of a distinct two-layer model of SDN. The top layer of SDN, based on “software overlay” virtualization, focuses on agile connection management to adapt to the dynamic notion of the cloud. …
One of the challenges that wireline has faced (and it doesn’t need all that many challenges for gosh’s sakes!) is the “capacity gap”. If anyone thinks broadband Internet is profitable enough, you need to read somebody else’s blog. You need to deliver video, HD video, to make wireline work, and that’s a problem because traditional…
The departure of Microsoft’s top Xbox guy, Don Mattrick, for Zynga has raised again the profile of Microsoft’s still-secret-in-detail restructuring. Ballmer announced that the company would be working to be more focused on services and devices and less on software. Clearly there are going to be a lot of changes, but rather than speculating on…
Well, we’ve seemed to finally get beyond the rumor phase with NSN. Nokia has offered to buy Siemens out of the joint venture, one of several possible outcomes that I’d heard rumors on over the last several month. The big question is whether this will matter to NSN or to Nokia, and that depends on…
It’s been an interesting week for the markets, in all of the dimensions that drive us forward. There are glimmers of technology change in SDN, there are signs of vendor shifts, and there are macro indicators that might tell us a bit about demand. So, given that it’s Friday and a good day to take…

Cisco’s comments on its new “Application-Centric Infrastructure” vision is yet another proof point for my argument that Cisco has successfully played the weaknesses of SDN players against them. In military tactics, seizing the high ground is a maxim. So it is in marketing, and Cisco has done that with finesse. You can harp on about…

The SDN game never ends, possibly because nobody wants to diss a good market hype wave while it still has momentum, and possibly because there’s still room to do something useful given the rather vague utility of some current strategies. In any case, PLUMgrid has joined the fray with an offering they call “Virtual Network…
