FlowVisor is a network virtualization layer built on top of OpenFlow.  The FlowVisor allows a single physical network to be sliced into multiple logical OpenFlow networks, allowing researchers to run multiple OpenFlow controllers on the same set of devices.  The technical report details the FlowVisor’s design and slicing mechanisms as well as an evaluation of how well the FlowVisor enforces isolation between slices.

The features described in the tech report have been included in the newly released FlowVisor version 0.4, including:

* preliminary bandwidth isolation between slices

* improved OpenFlow message rate limting for switch CPU isolation

* per-slice virtual topologies

Both the technical report and the new version are available from the FlowVisor’s webpage:
