OpenFlow Wireless at Stanford

November 28th, 2008, Guido Appenzeller in OpenFlow Blog

The Stanford Experimental Wifi Deployment Team building Access Points

Just before thanksgiving the Wireless Deployment team put together 80 new wireless access points for a testbed at Stanford. These are PC Engines based APs that run the latest version of OpenFlow. The plan is to use them for mobility experiments as part of the POMI project, as well as mobility experiments done in Phil Levis’ group. Congratulations to Masayoshi Kobayashi and the whole team including Mayank, KK, TY, Michel, Peyman, Jiang, Nikhil, Brandon and Mikio (some of them pictured above).

OpenFlow mailing lists

November 26th, 2008, Glen Gibb in Announcements

We’ve created a couple of mailing lists for all things OpenFlow. If you’re interested in OpenFlow or are actively using OpenFlow then we encourage you to join one or more of the lists.

The new lists are:

  • OpenFlow-announce — a low-volume list for OpenFlow announcements including new versions of the specification and reference design releases
  • OpenFlow-discuss — a list for general discussion of OpenFlow related topics including deployment, use, applications, controller development

OpenFlow at Supercomputing 2008!

November 23rd, 2008, dgu in OpenFlow Blog

OpenFlow made its latest appearance at the Internet2 booth for the 2008 Supercomputing convention in Austin, TX.  Adam Covington and David Underhill presented OpenFlow over four days to attendees from diverse backgrounds (industry, academia, and media) and diverse locations (Japan, Netherlands, and more).  We were able to show off our latest demo which included a VOIP phone in the OpenFlow network.  Attendees could place a call to the phone, see the flow to the phone show up in real-time, and then actually hear the latency of the echo as the flow was re-routed on the fly to go from Stanford to Japan, all over the US, and finally back.

To see photos from convention, go here — you will see the OpenFlow booth in action (along with our prime spot near the Network Operations Center)!

GEC3 Demo Photos and Slides

November 17th, 2008, Guido Appenzeller in OpenFlow Blog

Two weeks ago we had a great demo of OpenFlow at the third GENI Engineering Conference. Things we demonstrated included:

  • A centrally controlled OpenFlow network with OpenFlow switches deployed at Stanford, Internet2 and JGN2plus in Japan.
  • Virtual machine mobility at Stanford. You can see this in detail in the SIGCOMM Demo Video.
  • Flow Dragging. David Underhill created a fantastic UI that allows you to change the path packets take in the network by dragging the flow with the mouse to new routers an example video is shown below.
  • Virtual machine mobility within JGN2plus and between Stanford and JGN2plus. A running virtual machine was migrated across the Pacific while hosts in Japan were communicating with it. The combination of OpenFlow and our controller allowed the virtual machine to change locations and maintain connectivity without changing IP address.

The demonstration OpenFlow network incorporated switches from (in alphabetical order) Cisco, HP, Juniper and NEC.

The slides for Nick’s talk before the demo are online here.

Thanks to Glen who was the technical lead on this demo, as well as to everyone else on the 30 person team from Stanford, HP, NEC, Internet2, Cisco and Juniper who made this a success.

OpenFlow in Technology Review

More press: Cracking Open Internet Hardware on Technology Review’s web site.  We haven’t seen any switches look like the one pictured… yet.
