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)

Prerequisites

• 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

How to get Help

• Always ask your tutors (tutorial helper/presenter/TA) first. They are the fastest way to solve the problem.
• If you are using a specific aggregate or tool, you should consider registering in their mailing list. It is a great way to get connected with other GENI users and it is an excellent source of wisdom.
• Send mail to the GENI help list: ​help@geni.net.
• If you want to chat real-time with other GENI users and ask questions, join us in a GENI chatroom.
• ​geni-gimi-users@googlegroups.com
