  1. Are you ready for the tutorial? • Grab a Worksheet and instructions • Did you do the pre-work? A. Do you have an account? B. Are you running the GEC17 Tutorial VM including both: • VirtualBox • GEC17 Tutorial VM image Do you have an account? Are you in the right room? This is the red track. GENI Portal is at: • http://portal.geni.net

  2. Tutorial: Getting Started with GENI - Part I Sarah Edwards and Niky Riga, GENI Project Office 21 July 2013

  3. Hands On Exercise Do a Simple Layer 2 Experiment in GENI Reserve two VMs connected at Layer 2 VM VM Layer 2

  4. Understand GENI Terminology project slice experimenter resource aggregate

  5. Use the GENI Portal and Flack

  6. Experiment Workflow • Part I: Design/Setup • Part II: Execute • Part III: Finish

  7. The GENI Portal is… A web-based tool for experimenters to manage experimenters, projects, and slices. Includes simple tools to reserve resources. More to come in the future.

  8. Flack is … A graphical user interface (GUI) for: • designing topologies in GENI • reserving resources in GENI

  9. Experimenter An experimenteris a researcher who uses GENI resources Different types of experimenters have different roles and permissions: • Advisor vs Grad Student • Teacher vs TA vs Student Experimenter

  10. Projects Project Projects organize research in GENI Projects contain both peopleand their experiments A project is led by a single responsible individual: the projectlead Lead Slice Members

  11. Creating Projects • Only project leadscan create projects. • Project namesare public, unique and permanent • A project may contain many experimenters; an experimenter may be a member of many projects • Projects have an optional expiration (e.g. for classes, tutorials) For today’s tutorial we will all join a project which expires in about a week

  12. Experiment Workflow • Part I: Design/Setup • Part II: Execute • Part III: Finish

  13. Part I: Establish Management Environment 1 Pre-work: Design your experiment 2.1 Pre-work: Create a GENI account 2.2 Pre-work: Project lead adds you to project Project Name: GEC17 2.3 Generate and Download SSH Keypair Tutorial instructions: http://groups.geni.net/geni/wiki/GEC17Agenda/GettingStartedWithGENI_I/Procedure

  14. Creating a GENI account • GENI Portal is at: https://portal.geni.net • Anyone with an account at a supported identity provider (usually your school or employer) can log in, but they will have no privileges • If you don’t have such an account, we will make you an account at the GPO Identity Provider • You must be a member of a project to do anything interesting

  15. InCommon Leverage InCommonfor single sign-on authentication Experimenters from 304 educational and research institutions have InCommon accounts • For many experimenters: • no new passwords • familiar login screens

  16. Using ssh with a public/private keypair Login to all GENI compute resources using ssh with a private key • The public key is loaded onto the node when you reserve resources. • You provide the private key when you log into the node. There are several ways to offer your private key to ssh. No password! You should never be prompted for a password to log into a GENI compute node. If you are, something has always gone wrong.

  17. Expiration and renewal slice expiration time ≤ project expiration time each resource expiration time ≤ slice expiration time each resource expiration time ≤ aggregate’s max expiration project slice resource resource (optional) project expiration time resource resource expiration time slice expiration time now In general, to extend the lifetime of your resource reservation, you must renew the slice and allresources

  18. You are here Profile Help Projects Slices Log Messages

  19. Generate SSH Keys Login Join Project 2

  20. In your local VM … > mv ~/Downloads/id_geni_ssh_rsa ~/.ssh/. > chmod 600 ~/.ssh/id_geni_ssh_rsa > ssh-add ~/.ssh/id_geni_ssh_rsa 2

  21. Resource A resourceis a piece of infrastructure A resource can be real or virtual. Resource specifications are used to describe and request resources. Examples: • Compute: computer vs virtual machine (VM) • Wireline Network: VLAN or OpenFlow • Wireless: WiMAX

  22. Aggregate InstaGENI Rack ExoGENI Rack An aggregatemanages a set of reservableresources Aggregates include: GENI racks OpenFlow WiMAX

  23. Slice A sliceis a container of resources used in an experiment. A slice can contain resources from one or more aggregates A slice is in a single project A slice has an expiration Slice names are public, reusable and unique

  24. Putting it all together Member: project Lead: Experimenter slice Experimenter aggregate resource resource Layer 2

  25. Part Icontinued:Obtain Resources slice 3.1 Create a slice 3.2 (optional) Renew your slice 3.3 Reserve two VMs at on aggregate 3.4 Check Whether VMs are Ready to be Used VM VM Layer 2

  26. Create Slice 3.1

  27. Extend slice expiration 3.2

  28. Extend slice expiration Extend resource expiration Launch Flack 3.3

  29. username slice name all available aggregates 3.3 Launch Flack

  30. Draw two VMs connected by a link 3.3

  31. Change names of VMs If using ExoGENI resources, set size of VM to small 3.3

  32. Set IP and mask of interfaces 3.3

  33. 3.3 Reserve resources

  34. Resources are READY!!! 3.4

  35. Experiment Workflow • Part I: Design/Setup • Part II: Execute • Part III: Finish

  36. Part II: Execute Experiment Internet ssh 4.1 Login to nodes (two nodes: client & server) 4.2 Download and compile experiment software 5 Execute experiment 5.1 Send IP Traffic 5.2 Disable IP and send Layer 2 (non-IP) Traffic 6.1 Logout of nodes Control Interfaces client server Layer 2 Data Interfaces Experimenter

  37. Login 4.1

  41. Experiment Workflow • Part I: Design/Setup • Part II: Execute • Part III: Finish

  42. Part III: Finish Experiment When your experiment is done, you should always release your resources. • Normally this is when you would archive your data • Delete your resources at each aggregate project resource experimenter aggregate slice

  43. 7 Delete Resources

  44. Congratulations! You have… • Run your first GENI Experiment! • Exercised your knowledge of GENI terminology • Used the GENI Portal and Flack

  45. What’s Next? • (If needed) Request a permanent account • Are you a Professor or PI? • Ask to be a Project Lead so you can create projects • Invite students to join your project • Are you a Student? • Ask your professor to create a project • Request to join that project Keep experimenting!

  46. Coming up • In Part II • Automate the process of reserving topologies with the software already configured • Learn how to use another tool for reserving resources (omni) • Differences and strengths of the two flavors of GENI rack • In Part III • Learn how to instrument your experiment to automatically collect measurements • Later at GEC • Beginner and Advanced OpenFlow • WiMax • Get one-on-one assistance • Experimenter Drop In on Mon Afternoon • Coding Sprint, Experimenter and Operations Tutoring on Tues Afternoon

  47. Welcome to GENI!
