OpenFlow Demos at GEC8

July 21st, 2010, Guido Appenzeller in OpenFlow Blog

Today was the demo session at the GENI Engineering Conference in San Diego and the demos included a number of OpenFlow systems.

OpenFlow at GEC8

  • Integrated Control Framework Demo by a joint team of Stanford University and BBN. Using the OMNI command line tool, a researcher can reserve both PlanetLab compute nodes as well as an OpenFlow based networking substrate. The demo used the Expedient aggregate manager for OpenFlow Networks as well as the Opt-In manager. Essentially all of this demo came together over the past 4 weeks due to a heroic effort of the Stanford and BBN teams. Wiki page with more information is here.
  • Expedient, a control framework with a graphical UI for OpenFlow based resources. The version demonstrated additionally can be accessed via the GENI API through a proxy.
  • Aster*x, the OpenFlow based load balancer. This is the successor to the plug-n-serve system and the demo ran across a number of OpenFlow networks including Stanford, BBN, Princeton, Indiana and University of Washington.
  • Transport and Aggregation. This was a combination of the aggregation demo from SIGCOMM 2009 and the optical transport integration done together with Ciena. Details here.
  • WiMax. A demo from the OpenRoads team done together with two other WiMax demos at the conference.
  • Clemson University showed their graphical UI for configuring the slices on their local OpenFlow deployment. The UI looked great and there are a number of similarities with the Expedient UI.

Thanks to the 20+ people involved in putting these demos together, they were a big success. A few pictures below, more in the photo gallery of the demo session.

Updated: OpenFlow in Computerworld

October 30th, 2008, Guido Appenzeller in OpenFlow Blog

Tim Greene from Computerworld has a very nice article about OpenFlow, vendors that have implemented it and the demo at the GENI Engineering Conference. It is also up on Networkworld.

The GENI Demo just happened a few minutes ago, and it safe to say it was a huge success. We demostrated both virtual machine mobility as well as arbitrary flow routing. More exciting updates on OpenFlow coming soon.

Update: International coverage of OpenFlow in Japanese, Portuguese, Italias, Spanish, Polish and Swedish after the jump.


NEC Press Release for GEC

October 29th, 2008, Guido Appenzeller in OpenFlow Blog

NEC today announced their participation in the GEC3 OpenFlow demo, and their intention to support OpenFlow going forward. Press releases are online in English and Japanese. The GEC OpenFlow demo includes several NEC Switches at Stanford as well as in JGN2plus in Tokyo. NEC has been instrumental in working with Stanford to make this demo happen across continents.

The NEC IP8800 switches used in the demo are some of the best OpenFlow hardware that currently exists. They offer a good fan-out and are able to do OpenFlow at line rates. The only bad news is that what we are using are prototypes and they are not available commercially. However to quote from the release:

“NEC plans to support OpenFlow features in its future products and  to encourage universities, public testbed projects, and researchers to  experiment with innovative network ideas. “

So far we have had fairly few details about OpenFlow capable hardware on this blog, but expect this to change in the future. If you are interested in OpenFlow hardware, feel free to get in touch with us.

GEC Demo, OpenFlow Press Release

October 28th, 2008, Guido Appenzeller in OpenFlow Blog

We are getting ready for the OpenFlow demo at the Geni Engineering Conference 3. We had a first dry run yesterday which by and large went fine. Stanford also today did a press release on OpenFlow and the GEC Demo. Full text after the jump.
