[[PageOutline]] = Simple OpenFlow Tutorial with OVS Using GENI Portal = == Experiment Description == In this tutorial we are going to use a simple topology using [http://www.openswitch.org OVS] as an OpenFlow switch connected to three hosts. OVS is a software switch running on a compute resource. The other three hosts can only communicate through the OVS switch. Although the controller for the switch can run anywhere in the internet, we are going to run it on the same host as the OVS switch to minimize the required resources. We are going to use this setup to write simple controllers and experiment with the capabilities of OpenFlow. For this tutorial we are going to use the [http://www.noxrepo.org/pox/about-pox/ PoX controller], this is just an example of [wiki:OpenFlow/Controllers many controllers]. The OVS switch that we use runs in userspace which although not optimized for performance, it is enough for getting acquainted with OpenFlow.
