I’m switching the updates mailing list to mailchimp so I can post emails with more “stuff” from time to time that’s not posted on the blog. The signup is under the “hamburger menu” on the top left corner.

A new use case looks at how to use SDN to securely bridge on-premises assets with resources in the public cloud or virtual private clouds.
Avi won't comment, but Time Warner Cable already spoke for them.
In a new set of benchmark tests, key industry players prove NFV is a viable option for the network edge.
Well, if you thought SDN introduced a lot of terminology, you’ll love NFV! The good news is that ETSI, which defines NFV, does a great job documenting NFV, with extensive term and acronym lists to support other documents about the details of NFV architecture. Several of the ETSI NFV docs provide some great stepping-stones for understanding the basic concepts and terminology, which is where we’ll go in this post.
This is the last in a related series! The other posts:
One of the challenges with this blog is figuring out how much prior knowledge to assume. If you don’t know much at all about NFV, read this section for a quick intro. Otherwise, skip to the next heading.

Think of every networking device used in the IT world. Those include routers, switches, firewalls, intrusion detection systems, load balancers, and so on. Traditionally, those devices have indeed been devices – purpose built hardware, running some OS that performed the networking function.
While you’re thinking of the old way to network, Continue reading
A statistician is someone who can put their head in a hot oven, and their feet in a bucket of ice, and say, “on the average, I feel fine.”
Before we move completely into a world where people are counseled, “use the data, Luke,” disregarding their own beliefs and feelings, we need to have a little discussion. As an example of what we might get wrong, let’s take a look at some interesting problems in the polling from recent elections. According to one article (which happens to have all the numbers conveniently gathered in one place) —
These aren’t random events — they are repeated time and again in elections through the last Continue reading
I am very glad to announce that Roy Lexmond from my April CCDE training class passed his CCDE Practical exam yesterday in France. Below is his success story and here is his earlier feedback for the class. I should say that He really likes the design and open to learn new things and very clever.… Read More »

Alcatel-Lucent expands its carrier SDN portfolio with Network Services Platform.
Your development team has completed weeks of work, delivering their masterpiece-an application-to IT for deployment, but it doesn’t work.
See, the developers made use of a different port, that now needs to be opened on the firewall so end users can communicate with the software. IT changed the firewall rule, but didn’t tell development, so they never even knew it was an issue. Later, they create another application with the same issue, except this time, it will be deployed in a different environment.
No procedure or policy was created to capture all of the changes necessary to successfully deploy the app, so the same thing happens again. It’s a vicious cycle.
IT departments struggle to manage thousands of configurations and hundreds of applications with everyone working in silos. Teams who develop the apps frequently are not on the teams that use them. Meanwhile, operations teams deploy apps they didn’t write and have to convey to the development team when changes need to be made in order for them to work in this new and foreign-to-development thing called "a production environment".
Sound familiar?
Today’s IT environments are extremely complex. In the past, applications and hardware were closely connected. Apps came from Continue reading
