Early last year I drew a strategy map of all the elements in a Software Defined Ecosystem for a client. I drew another one a couple of weeks back to explain how the current vendor focus on controllers, and specifically, OpenDaylight is changing the nature of the market. The comparison is striking.
I doubt that anyone bought a Vblock because it was a market leading networking strategy. I’ve been a supporter of VCE but today I’m doubtful that choosing Cisco ACI is good strategy for their customers. My view is that most customers buy VCE Vblocks as a VMware platform. What VCE offers is a services package of fully supported storage, compute and networking that removes customer risk around VMware deployments while reselling EMC & Cisco hardware.
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.
