    33== Overview: ==
    4 This tutorial is designed to give insight into how OpenFlow can be used to conduct network experiments over WiMAX. As background, a vertical handoff is the (ideally seamless) migration of a network connection from one network interface to another of a different technology. An example might be your cell phone transitioning from a WiFi to a 4G connection while streaming a video. Vertical handoffs are traditionally handled by the network infrastructure,  providing little-to-no control of the handoff execution at the client. Clemson University is developing a client-initiated and controlled vertical handoff. This project is being conducted using GENI resources -- namely Clemson's GENI WiFi and WiMAX testbeds. Development has also been done on the Orbit testbed at Rutgers, which is where this tutorial and GENI experiment will be conducted.

    8 This tutorial will be conducted on the grid testbed at Orbit and will walk you through how to conduct an OpenFlow-based vertical handoff over WiFi and WiMAX. Three Ubuntu Linux images have been prepared for you and are available for this tutorial – (1) a client, which will initiate the handoff, (2) a server, which will serve as a correspondent node for the client, and (3) a WiFi access point (AP), which will provide a WiFi network over which the client and the server can communicate. The grid testbed at Orbit has complete WiMAX coverage via a single WiMAX base station (BS). This BS will provide the WiMAX network over which the client and the server communicate. The client will switch between its wireless interfaces by simply executing a couple of Bash and Python scripts. These scripts will leverage the Floodlight OpenFlow controller to in order to perform the switch.
