Simple OpenFlow Tutorial with OVS Using the GENI Portal

Experiment Description

In this tutorial we are going to use a simple topology using OVS as an OpenFlow switch connected to three hosts. OVS is a software switch running on a compute resources. 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 PoX controller, this is just an example of many controllers. The OVS switch that we use runs Auserspace which although is not optimized for performance, it is enough the purpose of getting acquainted with OpenFlow.
