Cyan’s Telesystem win in packet-optical for its Z-series and SDN technology is an interesting indicator of some major metro trends. While it’s victory over TDM is hardly newsworthy, it does show that packet advantages over TDM can justify a technology change—and any time you can justify technology change the barrier to doing something revolutionary is…
So near, and yet so far! How many times have we heard that comment? In the case of NSN with their recent deal with CDNetworks, we have a current example. NSN is seeing beyond the present, but they’re not yet seeing the future of content delivery. That might mean they’re not seeing, or optimizing, their…
What does AT&T’s decision to buy Leap Wireless, Cisco’s decision to do a cloud partnership with Microsoft, and Amazon at three hundred bucks a share have in common? They’re symbols of a market in transition and a call for action to start gathering your troops for some coherent planning. Traditional communications services, which are services…
Yet another set of Street reports and research reports have stopped just short of describing the PC market as “dead”, though a close analysis of the data seems to suggest that the declines are hitting a plateau. My view has always been that we’re seeing the “browser bunch”, those who see technology as a pathway…
Those of you who follow me on LinkedIn may have caught my creation of a LinkedIn Group called “CloudNFV”. Even though the group is currently invitation-only I’ve received many requests for membership, and a select few found the CloudNFV website and figured out a bit of what was going on. Craig Matsumoto of SDNCentral was…
We clearly live in a virtual world, in terms of the evolution of technology at least, but I really wonder sometimes whether everyone got the memo on this particular point. It seems like there’s a tendency to look at the future of virtualization as one focused on creating virtual images of the same tired old…
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…
