OpenFlow began at a consortium of universities, led by Stanford and Berkeley, as a way for researchers to use enterprise-grade Ethernet switches as customizable building blocks for academic networking ...

Earlier this year I wrote about a new concept called software-defined networking, which uses the OpenFlow programming interface to virtualize network resources.

With today’s OpenFlow Controllers, the latency of the path from the embedded OpenFlow Protocol in our firewall, starting with the TCP/IP protocol stack in the firewall, through the control ...

We've also heard from vendors that even with example OpenFlow implementations in NOX, Open vSwitch, and other projects, it can still take 90-120 days to implement and test a basic OpenFlow 1.0 agent.

Amin Vahdat, a principal engineer at Google, said, “I think the killer app is out there: Stanford is running the Gates building on OpenFlow.” Vahdat was referring to Stanford University’s ...
