Enterprise GENI, the OpenFlow based Network Substrate that is part of the large-scale GENI effort funded is featured on the GENI home page today. GENI uses the FlowVisor with an added-on Aggregate Manager to virtualize a network. Recently at Stanford we demonstrated how to use eGENI together with PlanetLab, allowing control of both computing and network infrastructure through a single framework. For more information, have a look at the article.

FlowVisor is a special purpose controller that allows multiple researchers to concurrently manage the same OpenFlow-enabled network. If we say a network slice is a collection of physical resources and classes of traffics, then FlowVisor is the logic that manages resource allocation among slices and enforces isolation between them. Thus using FlowVisor, research and production traffic can safely co-exist on the same underlying hardware.

We believe that FlowVisor will be an important component on the path of enabling research in your network.
