= Topology = [[PageOutline]] = Tutorial: Experiment Orchestration and Instrumentation using LabWIKI = == Schedule == Wednesday 8:30 A.M - 10:30 A.M (with a break for lunch) == 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 two central nodes 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: * [http://groups.geni.net/geni/wiki/GENIFIRE/Labwiki/Part1/Introduction 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 * [http://groups.geni.net/geni/wiki/GENIFIRE/Labwiki/Part2a/Introduction Add flow statistics] (1/2 hour) * [http://groups.geni.net/geni/wiki/HowTo/LabWikiGraphUsingCSV CSV to OML (Overview)] (1/2 hour) == Prerequisites == - A GENI/FIRE account, if you don't have one [wiki:SignMeUp sign up!] - Familiarity with how to reserve resources with any of the Tools (jFed, GENI Experimenter Portal, Omni, Flack). If you don't know you can take any of the tutorials: * Reserving resources using jFed [http://fed4fire-testbeds.ilabt.iminds.be/ilabt-documentation/tutorials.html#introduction-and-getting-started tutorial] - Familiarity with [http://fed4fire-testbeds.ilabt.iminds.be/ilabt-documentation/accessingnodes.html logging in to compute resources]. - Introduction to !LabWiki [http://groups.geni.net/geni/wiki/GEC18Agenda/GettingStartedWithGENI_III_GIMI 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 ==== Please Arrive With: ==== A Laptop == 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 [wiki:NikySandbox/GENIExperimenter/GENICommunity#Joinusermailinglists 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: [mailto:help@geni.net]. * If you want to chat real-time with other GENI users and ask questions, [wiki:HowTo/ConnectToGENIChatRoom join us] in a GENI chatroom. * geni-gimi-users@googlegroups.com ==== Results ==== == Tutorial materials == Instructions: See [http://groups.geni.net/geni/wiki/GENIFIRE/Labwiki/Part1/Introduction Agenda Details] Slides: * [http://groups.geni.net/geni/attachment/wiki/GEC20Agenda/LabWiki/GEC20%20I%26M%20Tutorial.pptx Powerpoint version] * [http://groups.geni.net/geni/attachment/wiki/GEC20Agenda/LabWiki/GEC20-GIMI-Tutorial.pdf PDF version]
