As I stated in my early vendor impressions blog I have been following NECs development of their OpenFlow controller for a while. Back in 2011 when NEC first announced its controller the only other controller I had ever heard of was FloodLight.
Fast nearly forward four years and the NEC controller has grown up considerably. One of the keys to the early commercial success of NECs controller is the OpenFlow extensions that they deploy to help alleviate some of the scale issues with the base OpenFlow specification. NEC advertises that each controller can manage 200 switches, 3,000 virtual tenants (VTNs), 10,000 VLANs and one million flows.
To aide scale NEC has developed an orchestration solution which increases scale by a factor of 10 which interesting enough can orchestrate both NECs PFC (Programmable Flow Controller) as well as HPs VAN (Virtual Application Networks) controller. This increase scale of the NEC solution to a total capability of 2,000 switches and 10 million network flows. For more information see NECs site: http://www.necam.com/sdn/doc.cfm?t=PFlowUNC
Lastly, as I tweeted, NEC pulled off a flawless demo showing off both Hyper-V integration with their PF-1000 virtual switch and service insertion by redirecting targeted flows to a firewall. I was most impressed by the demonstration as it really shows how SDN solutions are really starting to gel. It is no longer an abstract and academic unicorn theory topic. There are real solutions built on real SDN protocols (IE OpenFlow) that really work.
