There was another major demonstration of OpenFlow last week at SuperComputing 2009 conference in Portland, Oregon. It was jointly implemented with Ciena Corp., a major provider of communications networking equipment, software and services. This was the first demonstration of an OpenFlow implementation on a hybrid packet/circuit switch, in support of the draft experimental extensions to the OpenFlow specification for circuit switches.
As a proof of concept, we built a simple OpenFlow enabled packet and circuit switch network using carrier-class Ciena CoreDirector CI switches. The CDs natively support the OpenFlow protocol for their packet and circuit switching fabrics. We then built an application in the OpenFlow controller that sets up, modifies and tears down packet and circuit flows on demand and dynamically responds to network congestion. Learn more about the demo in the OFC’10 invited paper on the publications page. Our larger goals and motivations are detailed here.
Thanks to Dan Getachew, Preeti Singh, Lyndon Ong, Jim Archuleta, Puneet Gupta, Ashok Kumar, Ritesh Ralhan and the rest of the Ciena development team, as well as Yiannis Yiakoumis, KK Yap, and Vinesh Gudla from the Stanford side. Thanks also to the Ciena Marketing and Sales teams for putting together the demo booths, material and other support — it was good to see the buzz the demo created in the Research & Educational Networks (REN) community.
