I. Basic GENI Desktop Operations

  • Part I: Setup
    • Follow the instructions of the general GENI Desktop tutorial to create a topology with three Xen nodes as shown below.

  • Part II: Excute
    • Step 1: Copy a file to the selected nodes.
      • Download these two files (runs, runc) to a local directory.
      • Click "Upload File"
      • Highlight two nodes (A and B) *
    • Step 2: Run a command on the selected nodes.
      • Click on "Command"
      • Highlight all three nodes (A, B, and C)
      • Click on "Set Selection"
      • Type "sudo apt-get install iperf" in the text box.
      • Click on "Run Command"
    • Step 3: Monitor the traffic of the selected interface.
    • Step 4: Login by ssh to the selected nodes.
  • Part III: Finish
    • Teardown experiment

II. Introduction to OpenFlow

A brief introduction to OpenFlow can be found at [ ]

III. Flow Installation and Monitoring

  • Part I: Setup
    • Step 1: Create two slices, one for the controller and one for an experiment using OVS nodes.
      • For the controller slice, drag one "AAG Controller" node to the canvas. Check "Public IP address" box for the controller node.
      • For the experiment slice with OVS nodes, create a topology consisting of of three OVS nodes and two Xen nodes as shown below.
    • Step 2: Figure out the public IP address of the controller after the controller slice is created.
    • Step 3: Run an initialization script " " on all OVS nodes in the experiment.
  • Part II: Execute
    • Step 1: Install, list, and delete flows on the experiment
      • Click on "Flow Install". Fill in the IP address of the controller.
      • Select a path in the topology and highlight it.
      • Fill in the form to set the flow.
      • You can also try list and delete flows.
    • Step 2: Monitor per-flow performance
      • Click on "Flow Monitor".
      • Choose a flow to monitor at a selected node.
      • Send traffic (ping, iperf, etc) from end host A to end host B in the experiment.
  • Part III: Finish
    • Teardown experiment
