Agenda / Details


Apply your knowledge and skills about GENI, OpenFlow, and general SDN (Software Defined Networking) topics. Develop a vertical handoff experiment between WiFi and WiMAX in the Orbit testbed. Learn how to write custom modules for Floodlight -- a popular OpenFlow controller -- and connect your customized controller with Open vSwitch to implement the framework necessary for the SDN-based vertical handoff.


Basic understanding of:

Please Arrive With:

  1. A GENI Experimenter Portal account
  2. A laptop with ssh installed. Any operating system will be suitable.


At the conclusion of this tutorial, participants will:

  • Perform a vertical handoff between WiFi and WiMAX in the Orbit testbed
  • Understand the interrelation of the software components used to perform the handoff
    • Floodlight
    • Open vSwitch
    • OpenVPN
    • Initialization and handoff scripts
  • Use the Floodlight OpenFlow controller's Static Flow Pusher API
  • Become familiar with the internal structure of the Floodlight OpenFlow controller
  • Read, understand, and compose basic Bash and Python scripts
