One of the key business drivers behind SDN is to extract value from network connectivity. Before SDN, the functionality derived from connecting servers to switches was inherently valuable. In the post-SDN era, the network has services value instead.
HP Sentinel is an SDN Security application that combines a reputation database, HP VAN Controller and OpenFlow to build a Campus security solution. Here is a quick overview of the process and how you can mix existing security technology with standards-based OpenFlow/SDN to provide a useful campus security tool. This product is expected to reach the market later this year.
I’ve been digging deeper into the SDN architectures over the last few days and there may be a pattern starting to emerge. I’m currently figuring that there are four broad classes of SDN technology that you can fairly neatly classify the current products from vendors. I’m classifying SDN Solutions into three categories of Micro, Centi and Kilo as well as classifying physical devices for SDN systems into three classes of Breve, Medius and Magnus.(Yeah, OK, I’m not good at names.)
Intel announced the FM6700 chipset at the Intel Developers Forum in Sept and I missed this particularly interesting piece of information that will upset the OpenFlow haters: For the SDN networks, the FlexPipe frame processor can be used to parse and process SDN packets. The switch also supports 4,000 complete OpenFlow 12-tuple table entries that […]
In a recent discussion someone asked the relatively simple question “What does Programmable Networking even mean ?” and, after I stumbled around trying to explain, agreed to write something that attempted to explain what I see as the basic requirement that networking has not met. Here are some ideas just jotted down to open the discussion a bit wider.
This article from Mike Fratto at Current Analysis is great observation. Here is my view on the core topic: Networking vendors need to embrace homogeneity—that’s my first bit of advice—and present the most homogenous network to the virtual environment they can. By being homogenous, enterprises can swap out networking with far less disruption than having […]
VMware NSX got it’s official launch this week at VMworld. As a measure of how important VMware regards NSX, the first keynote on the first day is Martin Casado doing the official presentation.
My general view is the NSX is the real deal. I have been talking and writing about OpenFlow since May 2011 and many have complained that SDN isn’t important and I should focus on real network issues. Well, it should now be clear that SDN is a serious strategy issue and we might have been ahead of the market.
