NEC leverages OpenFlow to reduce transmission overload on cellular networks

NEC-ProgrammableFlow-OpenFlow-AndroidNEC continues to be a leader in the OpenFlow innovation movement.  This week in Tokyo our colleagues in Japan at NEC Corporation are demonstrating another first:  OpenFlow for Android, at iExpo in Tokyo on November 11 and 12.

Atsushi Iwata, NEC’s Senior Manager for System Platforms Research Labs, presented our findings at the Stanford Clean Slate CTO Summit this week.  Just a side note:  for those of you unfamiliar with Clean Slate, this is the interdisciplinary research program out of Stanford that has set the ambitious mission of “reinventing the Internet”.   A number of initiatives and innovations have come from Clean Slate, not the least of which is OpenFlow 1.0.  NEC, Deutsche Telekom and Stanford were the original charter members of Clean Slate, so as you can see we have been working with OpenFlow now for almost four years.

As detailed in an NEC news release recently, the Communication Control Technologies for networks and mobile devices being demoed at iExpo 2011 are designed to help reduce transmission overload for mobile carriers and customers.  Today communication carriers use data offload to deal with increases in cellular network traffic, automatically switching wireless connections from cellular networks to other high-speed wireless networks, like wireless LAN, when they are available.

The problem with this scenario is that wireless LAN connections are frequently lost due to limited coverage (those of you in major US cities surely know about this), and security is weaker than cellular networks.

NEC’s OpenFlow controller can control mobile device communication and select the most appropriate network, for higher quality, more flexible communication services.  The technology also leverages the advantages of different networks simultaneously; for example, the high-speed networking of wireless LAN can be offered at the same time as the connectivity and security of cellular networks.  This OpenFlow demonstration will control mobile device communications and switch functionality for Android.

Business policy and application needs can drive mobile communications and network switching for a more responsive, agile network and improved communications quality.   And Mobile Virtual Network Operators (MVNO), who provide mobile phone services using the infrastructure of other carriers, can select connections from multiple mobile networks with NEC’s OpenFlow controller on the network side, further enhancing their service offering.

One of the big questions coming out of this month’s OpenFlow Symposium in San Jose was around OpenFlow use cases… providing control for networks and mobile devices to reduce transmission overload surely will stir some interest.

And the Winner Is….

altI guess you can say there’s a competition for just about everything in the world.  Hot dog eating, wife carrying, ugliest dog and fastest computing.  Although NEC hasn’t won a best beard contest in a while we just won first place at the HPC Challenge with our Earth Simulator. 

Our “Earth Simulator” you ask? 

Allow me to give you the technical answer: The Earth Simulator is a parallel vector computing system that was launched in March 2002 at JAMSTEC. The renewed Earth Simulator, put into operational use in March 2009, consists of 160 nodes of the SX-9/E system with a theoretical peak performance of 131TFLOPS, which also boasts the world fastest CPU core of 102.4GFLOPS.

Now allow me to translate: A really fast computer that would probably be a killer gaming PC.
