OpenFlow at GEC9

November 7th, 2010, Guido Appenzeller in OpenFlow Blog

At the GENI Engineering Conference 9 last week in Washington DC there were a number of demos based on OpenFlow in both the demo session on Tuesday evening as well as during the plenary on Wednesday morning . In fact, it was very exciting to see how the majority of the demos at least in the plenary session were using OpenFlow as well as the Slicing infrastructure that GENI uses to manage its OpenFlow based networks. In the research community, OpenFlow is on its way to becoming the tool of choice for innovative new networking research and large scale experimentation.

GEC9-4646

For a complete list, have a look at the List of Plenary Demos and the List of Posters on the GPO Web Site. One of the most amazing demos from the demo floor was Indiana Universitie’s GlobalNOC WorldView in 3D. If Minority Report meets network management, this is how it would look like.

The Stanford OpenFlow team was present with two demos. The updated Load Balancing demo used VoIP to allow the audience to participate vie their cell phones. It also used a much larger topology spanning 10 local networks that spanned the continent and the National Lambda Rail backbone. It was followed by a new mobile handover demo from Stanford. It showed video streaming from a golf cart driving around the Stanford Campus. Stanford’s OpenFlow Network allowed the mobile client to make simultaneous use of multiple WiFi base stations and the Stanford WiMax deployment, without needing Mobile IP or any other similar solution. Demo pages for both demos should be up in the next weeks and we’ll post here again.

Congratulations to all the teams at GEC9! This was definitely the most impressive set of demos I have ever seen at GEC, and possibly at any networking conference.

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.

OpenFlow wins Best Demo and Best Poster Awards at SIGCOMM

August 20th, 2009, Guido Appenzeller in OpenFlow Blog

OpenFlow for the second time in a row won the best demo award as well as the best poster award at SIGCOMM 2009 in Barcelona. The OpenFlow “Room” at SIGCOMM showcased the use of the FlowVisor to divide partition the stanford production network at Stanford into 5 virtual slices and production traffic as well as 4 separate experiments on these slices. Each experiment had its own OpenFlow controller, and the FlowVisor segregated traffic as well as forwarding decisions betweek the slices.

The individual experiments that ran in parallel were:

  • OpenPipes, a system to prototype high-speed networking hardware by connecting separate components via an OpenFlow network.
  • Plug-n-Serve, a controller that takes a network of switches and turns them into a distributed load balancer.
  • OpenRoads, a demonstration of how multiple virtual mobility managers can coexist on a wireless network and increase transmission quality via bi-casting.
  • Aggregation, a demonstration of a controller and UI that can aggregate large numbers of flows into classes of traffic and manage them efficiently.

OpenRoads was separately named the best poster of SIGCOMM 2009.

Congratulations to everyone on the team including Rob, Glen, Masayoshi, KK, Jad, Yiannis, Nikhil, Srini, Tatsuya, Guru, Guido and Nick here in Barcelona and David, David, Mikio, Julius, Adam, Brandon and Paul in the US. Also many thanks to the teams from NEC, HP and Nicira, without them this would not have been possible.

Over the next weeks we will post videos of the demos as well as the posters itself on this blog. Stay tuned!

OpenFlow at SIGCOMM 2009

June 17th, 2009, srini in OpenFlow Blog

We are delighted to announce that the OpenFlow team has had three demonstration proposals and a poster accepted at SIGCOMM 2009. Be sure to stop by our booth to learn more about the potential of OpenFlow.

  • OpenPipes: A modular pipeline, built using OpenFlow, that allows functional modules to be moved around in the network, from one subsystem to another, while the system is running.
  • Flowvisor:  A special purpose OpenFlow controller that allows multiple researchers to run experiments safely and independently on the same production OpenFlow network.
  • Plug-n-Serve: A server-load-balancer, built from commodity components, that tries to minimize response time by controlling the load on the network and the servers using customized flow routing.
  • OpenRoads(poster): A framework for OpenFlow-enabled wireless mobility research.

Video of Mobile VMs Demo

December 4th, 2008, yiannisy in OpenFlow Blog

The last three months, we presented variations of our Mobile VMs Demo at different venues including SIGCOMM 2008, GEC-3 and Supercomputing 2008.

We demonstrated Virtual Machine mobility, client mobility and GUI-based flow dragging, on a centrally controlled network spanning across Stanford, Internet 2 and JGN2plus in Japan.

This video gives Openflow basic background and explains the demo with slides, pictures and video clips.

Check it out!

Video is also available in a larger size and HD.

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.

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.

Video of SIGCOMM Demo

October 29th, 2008, brandonh in OpenFlow Blog


Last August at SIGCOMM 2008, we presented a demo of OpenFlow where both game servers and clients could move around in a production network, while maintaining their connectivity to each other.

For anyone who missed the demo, or wants to share it with others, we’ve made a self-contained four-minute video that explains OpenFlow background and the demo – with slides, pictures, and video clips of those playing the game.  Check it out above, in web-size, or see it in 720p HD!

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.
