= STEPS FOR SETTING UP = 

== 1.  Obtain resources ==
For this experiment we are going to use resources in ExoGENI GPO or ExoGENI RENCI, we will need:
  * 6 VM (KVM): 2 act as regular hosts; 2 as regular switch; 2 as OpenFlow Switch (we will only program one)

[[Image()]]

If you are attending a Tutorial, the resources might have already been reserved for you, check with your instructor and skip this step. 

You can use any reservation tool you want to reserve this topology:
  * For Omni or Flack you can use the  [wiki:GENIExperimenter/RSpecs RSpec] that is published at: http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/ExoGENI/openflow-loadbalancer-kvm.rspec and the ExoGENI GPO AM or the ExoGENI RENCI AM
  * At the [https://portal.geni.net GENI Experimenter Portal] there is a public RSpec called "openflow-load-balancer-kvm" that you can use, and either GPO ExoGENI or RENCI ExoGENI as the AM

Look at the [http://groups.geni.net/geni/wiki/GENIEducation/SampleAssignments/OpenFlowLoadBalancerTutorial/ExerciseLayout#Prerequisites Prerequisites] for Tutorials about reserving resources. 


= Create an Experimental Topology for !LoadBalancing with OpenFlow = 
  - 1. Follow the tutorial on [http://groups.geni.net/geni/wiki/GENIExperimenter/Tutorials/PortalSimpleLayer2Example/SetupAccount SetupAccount] to get a GENI Portal Account
 - 2. Follow the instructions on [http://groups.geni.net/geni/wiki/GENIExperimenter/Tutorials/PortalSimpleLayer2Example/ObtainResources ObtainResources] to reserve a topology on GENI Portal
  - '''Note: choose resource `openflow-loadbalancer-kvm` as the rspec; `GPO ExoGENI` or `RENCI ExoGENI` as the Aggregate'''
 - 3. Once nodes are reserved and ready, log onto the reserved nodes following instructions here: [http://groups.geni.net/geni/wiki/HowTo/LoginToNodes LoginToNodes]
Done.
