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

When developing applications using OpenFlow, a small network of OpenFlow switches is often needed for testing and debugging. Using a simulated network for such development would be ideal, allowing more people to develop efficiently at their own pace. The ”OpenFlow Virtual Machine Simulation” (OpenFlowVMS) package is developed to create that virtual simulated network in your very own desktop/laptop.

OpenFlowVMS is a set of Python scripts that create that virtual simulated network automatically, letting developers concentrate on their real tasks and not fight the details of setting up a testbed.  The original version of this tool is developed by Ben and the folks at Nicira.  This version is a near complete rewrite using Python and XML for configuration.  Part of this tool is developed with support of DoCoMo USA Labs.  You can get the package and updates from

Hope you will enjoy having your very own OpenFlow network(s).
