Create the Experiment:

  • Login to the GENIDesktop As usual. If you need help see the GENIDesktop Manual Login page.
  • Create a slice as usual. If you need help see the GENIDesktop Manual Create A Slice page.
  • Allocate Resources for the topology below using JACKS in the GENIDesktop. If you need help see the GENIDesktop Manual JACKS page (but we are not using the topology listed on that page).

In this tutorial we will be using Open vSwitch (OVS) nodes to represent OpenFlow Software Switches and XEN VMs nodes to represent hosts . The general topology contains two hosts, h1 and h2 with 3 switches, s1, s2 and s3:

Draw this topology. Rename your nodes to match the given topology. Click node name, then type in the new name in the Name box in the left side dialog box.

Before allocating the resources, click the Extra Features checkbox. This will show the drop down for Select AAG (Adopt-a-GENI) Controller. You may choose between a "Floodlight Controller for AAG" or an "RYU Controller for AAG". For this tutorial we will be using the default option of "Floodlight Controller for AAG".

Click Allocate Resources Using This RSPEC

You can watch the allocation progress as the slice is allocated.

Once the allocation is complete the GENIDesktop will automatically load the Slice View page. Here the allocated topology will be shown. Note that two extra nodes have been automatically added to your topology. One is the AAG Contoller, AAGCTRL0 and the other is the Global Node GDGN0. These nodes provide the OpenFlow controller and the measuring controller respectively.

Once the resources have been allocated we must wait for the nodes to be created/booted. We can track the progress. As the nodes come up they will turn green. Any failed nodes will be red. Once all the nodes have been booted, the nodes will all return to gray.

After all the resources have been allocated and booted the GENIDesktop will run an Initialization and Instrumentation process that will configure, start up and attach all the OVS nodes to the controller. It will also start the monitoring of the slice.
