    99The system framework utilizes OF to achieve IP mobility and application-transparent handovers. It is designed to be easily deployed to universities that have OF-enabled campuses or that can provide a subnet or VLAN for handover experimentation. The framework was developed and implemented at Clemson as a part of the GENI WiMAX project. Fig. \ref{clemson-geni-handover} provides a general overview of how our testbed is constructed and how it integrates with the large-scale GENI testbed. At the architectural level, the framework allows OF-enabled mobile devices to roam across any OF-enabled wireless network. It requires a root OF switch as the testbed ingress/egress, as well as OF switches at each edge network. The challenge in building a testbed based on the framework is the required integration with existing network infrastructure at the campus. The testbed allows a mobile device to roam from wireless Network X (as illustrated in Fig. \ref{clemson-geni-handover}) to Network Y, preserving end-to-end socket connections that the device has with other hosts located either on the campus network or in the Internet. With these minimal assumptions, the testbed can be as simple or as complicated as desired. The design of our testbed can be divided into two major components: the network-level and the client-level.
