Agenda Details

Attendees will learn on how to use the LabWiki tool to plan, prepare, and execute experiments in GENI testbeds. Attendees will learn these steps by creating a simple start topology in which the central node will implement an OF-based learning switch and the functionality of that switch will be verified through an experiment script. We will give an overview on the inner workings of LabWiki, OML/OMF, AMQP, and the GENI experiment service.

The tutorial is structured as follows:

  • bring up slice run experiment (1/2 hour)
  • explain GIMI inner workings (1 hour)
    1. describe images (tools, postboot script)
    2. OMF/OML
    3. LabWiki
    4. Experiment script
    5. Short segment on OF
  • Extend topology (after deleting initial one) (1/2 hour)
  • Lunch
  • Extend experiment script (1/2 hour)
  • Add flow statistics (1/2 hour)
  • Large-scale demo (1/2 hour)


  • A GENI account, if you don't have one sign up!
  • Familiarity with how to reserve GENI resources with any of the GENI Tools (GENI Experimenter Portal, Omni, Flack). If you don't know you can take any of the tutorials:
    • Reserving resources using Flack tutorial
    • Reserving resources using Omni tutorial
  • Familiarity with logging in to GENI compute resources.
  • Create iRODs account
  • Introduction to LabWiki tutorial
  • Familiarity with Unix Command line - See "Tools" section
  • "Basic OpenFlow concepts". It is assumed that the attendees, already have an understanding of OpenFlow and its API
