The OpenFlow Road Trip

January 31st, 2010, Guido Appenzeller in OpenFlow Blog

This week Guru Parulkar and I (Guido Appenzeller) will visit the seven Universities that are part of the GENI¬†OpenFlow Campus Trials that are taking place this year. The reason why we will spend the week mostly in planes, cars and meetings with IT folks is that we feel we don’t fully understand yet what it will take to deploy OpenFlow at these universities. It is one thing to read a proposal or listen to a 30 minute presentation at a conference, but a very different thing to actually talk to the people who will have to deploy and support the hardware and software that will run production traffic.

Unless the winter weather stops us, we will within five days visit:

  • Rutgers
  • Princeton
  • GeorgiaTech
  • Clemson
  • University of Indiana (Bloomington)
  • University of Wisconsin at Madison
  • Washington University

We hope to post a short update from each university while we are on the road, as well as an overall summary at the end. This should be interesting. Stay tuned.

Rethinking the Internet with OpenFlow at U Wisconsin-Madison

September 17th, 2009, Guido Appenzeller in OpenFlow Blog

adityaProfessor Aditya Akella at the University of Wisconsin-Madison is teaching an advanced graduate level class on rethinking the internet architecture that makes heavy use of OpenFlow. A major part of the class is practical experimentation with OpenFlow. Specifically students will write NOX modules that implement new protocols which can then be run on the OpenFlow topology that he has set up. Some of the OpenFlow nodes in the topology are NetFPGA cards, thus it is additionally possible to try out new forwarding hardware. For more information have a look at the class home page and the reading list.

OpenFlow in Academia

June 3rd, 2009, srini in OpenFlow Blog

OpenFlow, I believe, provides an easy way to use actual switching/routing devices in an academic setting. There seem to be a few universities that are teaching OpenFlow in a lecture or are using OpenFlow for their course projects. Following is a quick list that I generated to appease my curiosity. If I missed your university, please send us a mail.

OpenFlow demo at the GENI CIO Meeting in Chicago

August 27th, 2008, Guido Appenzeller in OpenFlow Blog

We gave a short presentation of OpenFlow in the context of Enterprise GENI at the GENI CIO Meeting in Chicago today, and finished it with a live demo of the system running at Stanford. Everything worked very well, with the dashboard running in Chicago and us being able to demonstrate VM mobility and flow optimization (Thanks Glen and David U!).

There seems to be a lot of interests from University CIOs in OpenFlow as a potential tool for networking research. Specifically the ability to run production traffic and experimental traffic on the same switching hardware with good separation received a lot of questions. There seems to be a natural tension at Unviersities between networking researchers that want maximum flexibility, and the people operating the production network that want to keep everything stable and secure. An OpenFlow switch that separates OpenFlow and production traffic by VLAN seems to provide at least a partial solution to this problem.
