One of the interesting things about SDN is that it may be getting clearer because of things going on elsewhere. We still have a lot of SDN-washing, more models of what people like to call “SDN” than most would like, but there’s some clarity emerging on just how SDN might end up deploying. I commented…
Hint: It’s not how you think! HP is certainly at least one of the functionality leaders in the NFV race, and the fact that they’re an IT player is important to senior management at many operators. They’ve won what’s arguably the most important NFV deal yet (Telefonica), and they’re on track to deliver convincingly on…
I often get emails on my blogs from network operators (and of course network vendors too, but those are another story). One of the things I get from those emails that I find particularly fascinating is the difference in perspective on SDN and NFV between the pillars of power in operator organizations. We talk all…

Studies are always a good thing, and we have one now that could be particularly good for the industry. Working with AD Little, Alcatel-Lucent’s Bell Labs cooperated to generate a report (registration required) that outlines the benefits to be expected from SDN/NFV adoption. There’s good news and bad in the report, at least from the…
Pretty much everything these days is based on networking and software, which by current standards means that everything is SDN. The trend to wash stuff with terms like SDN and NFV is so pervasive that you almost have to ignore it at least at first to get to the reality of the announcement. So it…
We know we need to have security and compliance in SDN and NFV, simply because we have them today in other technologies. We also know, in at least a loose sense, that the same sort of processes that secure legacy technology could also secure SDN and NFV. The challenge, I think, is in making “security”…
Both SDN and NFV deal with virtualization, with abstractions realized by instantiating something on real infrastructure. Both have management issues that stem from those factors, which means that they share many of the same management problems. Formalistically speaking neither SDN nor NFV seem to be solving their problems, but there are signs that some of…
It’s obvious that there’s a relationship between NFV and the cloud, but for many the relationship is simply one of common ancestry. You host apps in the cloud and with NFV you host features there. Well, there’s a lot more to the cloud than just hosting apps or features. The cloud is the model of…
Here is an interesting question for you. If the gazelle evolves, does the lion also have to change? Of course, you’d say. A food chain generates a chain reaction to any significant alterations. Well, then, how about this one. If network services evolve to something very different, does enterprise network equipment also have to evolve? …
