n-casting using OpenFlow

Interesting demonstration about how a video stream can be rerouted/replicated on WiFi ap's in network to improve video quality ... The handover between AP's looks like running smoothly and all done with less than 300 lines of code.  Well done !

Openflow @ Google

Google team has managed to build the biggest openflow network in a production environment. According Urs Hoelzle, with openflow technology was possible to achieve high levels of networking efficiently and better levels of energy consuming in their data-centres.

Another nice article at wired magazine http://www.wired.com/wiredenterprise/2012/04/going-with-the-flow-google/ .

legacy protocol stack and openflow ...

Nice paper about legacy protocol stack move to o logically centralized
controllers using the OpenFlow protocol...

Check out! :)
ABSTRACT
Computing history has shown that open, multi-layer hard-
ware and software stacks encourage innovation and bring
costs down. Only recently this trend is meeting the net-
working world with the availability of entire open source net-
working stacks being closer than ever. Towards this goal, we
are working on QuagFlow, a transparent interplay between
the popular Quagga open source routing suite and the low
level vendor-independent OpenFlow interface. QuagFlow is
a distributed system implemented as a NOX controller ap-
plication and a series of slave daemons running along the
virtual machines hosting the Quagga routing instances.
