A special note of concern for my friends in the Boston area. I’ve spent a lot of time up there, and while all my personal friends seem safe a surprising number know others who were at least in the area of the blasts. I’m thinking of you all, praying for your safety, and hoping that…
Maybe-Holistic SDN Model?
One of my biggest frustrations about SDN has been the lack of a complete top-to-bottom architecture. All of the focus seems to be on the SDN Controller, and that’s an element that is a little functional nubbin that lies between two largely undefined minefields—the lower-layer stuff that provides network status and behavior and the upper-layer…
How to Judge the News at ONC
With the Open Networking Summit about to kick off it’s obvious that there’s going to be a lot of things going on with respect to SDN and cloud networking. The problem we have, in my view, is that all of this is a race to an unknown destination. We’ve picked apart the notion of SDN…
Butterflies and Markets
Well, the report on PC sales has pretty well demonstrated that we do have a new dynamic in terms of “personal computing”, a dynamic in which the device that took its name from the concept is falling out of favor. This is coming about because a seemingly small force–mobility–is driving a systemic change in human…

Networking’s Biggest Question
Can it be done? That’s a question that I’m sure gets asked a lot in our industry. We see or hear a news item or claim and we ask “the question”. Part of the prevalence of this favorite question is the cynicism bred of years of hype, of course, but part is also a reflection…
How Much Light in Open Daylight?
We’ve had a couple of potentially significant developments in the networking space, developments that seem on the surface to be contradictory. On the one hand, big firms like IBM, Cisco, Microsoft, and Ericsson have created an open-source project for SDN development, called “Open Daylight”. This suggests wide industry support for an open SDN framework, and…
Prepare to Read Earnings Tea Leaves!
We’re coming into that wonderful quarterly ballet that the financial industry calls “earnings season”, a bit of a misnomer given that we actually have four of them any year. Nomenclature notwithstanding, this is a good time to look at the health and ecosystemic pressures of tech overall. We’ll be getting at least a snapshot of…
Is Juniper Retreating from QFabric or Advancing to SDN?
We continue to see major vendor announcements on SDN, but obviously some are more responsive/revolutionary than others. Juniper has announced its EX9200 product, which it’s billing as a programmable core switch and also a stepping-stone toward SDN. There may be some significant news here, but it’s not on the SDN front—at least not for now….
Alcatel-Lucent Sets a High SDN Bar (But a Low Singing Standard!)
Alcatel-Lucent finally did their SDN announcement, and it was in most ways a major step forward for SDN, perhaps the biggest step taken by any of the vendors so far. However, as is often the case, the articulation may not do justice to the technology. In fact, in many ways the material was downright murky,…
