The OpenFlow Team in CCR

July 23rd, 2009, Guido Appenzeller in OpenFlow Blog

The current issue of Computer Communications Review mentions OpenFlow as part of an article on the GENI project. OpenFlow with the FlowVisor virtualization proxy are the technologies underlying the Enterprise GENI project at Stanford.

OpenFlow 0.9 Released

July 20th, 2009, Guido Appenzeller in Announcements, OpenFlow Blog

Today we released version 0.9 of the OpenFlow Switch Specification as well as the OpenFlow Switch Reference Implementation. You can find it on the download page or pull it directly from the public git repository.

OpenFlow 0.9 is a major step towards the 1.0 release, and it incorporates a large number of bug fixes, clarifications and new features including  failover, emergency flow entries, VLAN Priority Matching and support for ToS field re-writing. For a complete list of changes read the Release Notes or the more detailed Wiki Page.

For OpenFlow deployments, we recommend to use OpenFlow 0.8.9 for now. Nox, the NetFPGA and other OpenFlow Hardware at this point is not yet compatible with 0.9. We will post on the OpenFlow Blog as these get updated. Feedback and bug reports are highly welcome via Trac or the openflow-discuss mailing list.

This release would not have been possible without the work of (in alphabetical order) David Erickson, Glen Gibb, Brandon Heller, Mikio Hara, Bob Lantz, Justin Pettit, Ben Pfaff, Jean Tourrilhes and David Underhill, Tatsuya Yabe, Yiannis Yiakoumis as well as to the many other members of the OpenFlow community that provided valuable suggestions, feedback and testing.

Thanks to all of you!

Guido, Brandon & Mikio

OpenFlow appears in NewScientist Magazine

July 1st, 2009, Masa in OpenFlow Blog

OpenFlow was mentioned in an article titled “Building a crash-proof internet” which recently appeared in NewScientist magazine (pp.38-41, no. 2714, June 2009). The article describes the motivations for building large-scale, programmable, realistic testbeds and the NSF’s GENI project. OpenFlow is introduced as a practical platform to accelerate this effort.
