A preliminary release of the OFTest framework, code named dragonfly-1.0, is now available.  It can be downloaded with git via the command:  git  clone git://openflow.org/oftest.git.  Tar files of the core and pre-built directories are available at http://openflow.org/oftest.  The test framework is currently targeted to 1.0 but will be updated for 1.1 as that standard evolves.

You can subscribe to the OFTest email list which provides community support for the project at https://mailman.stanford.edu/mailman/listinfo/openflow-testing.

Various documents related to OFTest are available on the OpenFlow wiki.  The read-me file is available at OFTestReadme.  A tutorial is in the works and can be seen at OFTestTutorial.  A list of currently implemented test cases and planned test coverage is at OFTestListPage.  This is an open source project and contributions in the way of test cases and framework enhancements from the OpenFlow community are strong encouraged.

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.
• 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.

All events went swimmingly, with about 40 attendees.  The tutorial alternated between hands-on exercises and lecture, with topics such as OpenFlow motivation, history, interface, demos, availability, deployments, and community.  In the hands-on portion, each participant worked to learn the OpenFlow toolset and turn the provided hub controller into a flow-based switch. Fortunately, the 6499 miles and 200+ms RTT between Stanford and Gramado affected only one demo out of 6; most worked without a hitch.

The tutorial slide deck is available.

It was great to see the progress in OpenFlow deployment in each campus as well as the interesting researches happening on top of it. We together will continue expanding OpenFlow deployment including Internet2 and NLR.

We’re glad to see the increasing interest being shown in OpenFlow by industry, and we eagerly look forward to the availability of more OpenFlow-enabled hardware.

The implementation includes a user space switch, a kernel space switch and NetFPGA implementation and is based on OpenFlow v0.89.

It supports MPLS by adding two tupels to standard OpenFlow tupels, which can match on up to two top of the stack MPLS labels. The rewrite action is supported in flow table for MPLS tags, but other MPLS related actions (Push, Pop, TTL and EXP bits operations) are supported via MPLS-enabled virtual ports.
