In a recent letter to the editor of Network World, the letter’s author suggested that Software-Defined Networking protocols would likely go the way of ATM (Asynchronous Transfer Mode) and OSI (Open Systems Interconnection). To drive home his meaning, the author posed the question “Where are those protocols now?” In part because I have spent a [...]
The Medium-Hanging Fruit for SDN
May 20, 2013 by Leave a Comment
As hot as software-defined networking is today from a media perspective, there are still relatively few production deployments of it from companies not named Google and Baidu. The biggest challenge for mainstream enterprises is trying to understand what, exactly, one would do with an SDN. SDNs promise to deliver a more flexible, agile, programmable, virtual, [...]
The Changing Role of the IT Professional
May 16, 2013 by Leave a Comment
Over the last few months, I have moderated three software-defined networking (SDN) seminars that were produced by Network World. In each seminar a number of speakers spoke at length about the potential for SDN to automate the vast majority of configuration changes that are now done in a largely manual fashion, and in every session [...]
A Pox* On (Too Many) SDN Standards
May 13, 2013 by 1 Comment
What if you created a standards group that everybody wanted to participate in? I’m not saying that OpenDaylight Project represents all — or even the majority — of SDN stakeholders, but its current lineup of industry heavyweights will probably do for now. Announced on April 8, it is intended to ‘accelerate adoption, foster new innovation [...]
It’s Time for SDN Marketers to Step on the Gas
May 10, 2013 by Leave a Comment
There’s no networking topic I get more end-user inquiry on than software-defined networks (SDN). The types of questions I get are all over the map, making it difficult to get a good feel for what purchase intentions are. To get a better handle on what we might see in the way of SDNs investments over [...]
SDN: Lots of Smoke. Any fire?
May 7, 2013 by Leave a Comment
In a previous blog post I discussed the growing trend away from hardware specific solutions and towards solutions that feature software running on generic hardware. That trend took off several years ago with the introduction of server virtualization. In today’s environment it is difficult to read a trade magazine or go to a conference and [...]
The Amazing Network Chameleon
Apr 29, 2013 by Leave a Comment
I’ve always thought chameleons were cool. I actually had one when I was younger, and was fascinated by its ability to adapt to different surroundings by changing color. The networks of today are becoming technology chameleons that are adapting to meet the unique and ever-changing needs of their data centers and application workloads. No matter [...]
9 Technology Trends Driving The Adoption Of SDN
Apr 26, 2013 by Leave a Comment
Mike Fratto, my former editor at Network Computing, now a consultant at Current Analysis, recently wrote a blog entry that tried to cut through the 3 Hs of SDN — Hype, Hoopla and Hysteria — by posing what some consider the essential question of life (unless you’re a Monty Python or galactic hitchhiker fan, in [...]
Business Thrives When Applications Become Services
Apr 22, 2013 by Leave a Comment
With a basic web application, the user sends a request over the network to a server that returns the application or content to the user’s browser. The browser simply renders and displays the information from the formatted pages sent from the server. However, many of today’s web applications are much more complex with a lot [...]
