     20= STEPS FOR SETTING UP =
     21''' Using Omni to get physical PCs from ProtoGENI:''' [[BR]]
     22'''0. Get account: (Ignore this if you already have one) [[BR]]'''
     23Go to [https://www.pgeni.gpolab.bbn.com/reqaccount.php3 Request_GENI_Account] for an emulab account and to join a GENI project.[[BR]]
     24Apparently you need to join a GENI project (which is created by PIs/GPOs/others who have permission to do so) in order to use GENI resources.
     25
     26'''1. Prepare Omni''' [[BR]]
     27Here is a very good tutorial on setting up Omni environment: [http://groups.geni.net/geni/wiki/GENIExperimenter/Tutorials/HelloOmni HelloOmni] [[BR]]
     28Simply follow the tutorial to set up Omni.
     29
     30= Create an Experimental Topology for Firewall with OpenFlow =
     31'''1. Use Omni to create the topology: [[BR]]'''
     32Download the RSPEC from http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/fw.rspec [[BR]]
     33Next, we need to create this experiment using the RSPEC file: [[BR]]
     34  '''Step 1. Create slice (use a unique name for your slice):'''
     35{{{
     36omni.py createslice <slice name>
     37}}}
     38  Output should be something like the following (here I am using 'OpenFlowFW' as the sample slice name):

     262  Note: When dealing with specific slivers, we need to add "-a pg-utah" to specify which aggregate manager we want to use (i.e., from where we want to reserve the resources). In our case here, we are using utah aggregate.[[BR]]
     263  For a list of available aggregates, please see the file ~/.gcf/omni_config, check out `ProtoGENI AMs` section.
     264
     265OK. After this point, we are ready to log on to the nodes and do the OpenFlow FireWall experiments! :-)
     266
     267
     268= Create an Experimental Topology for LoadBalancing with OpenFlow =
     269To create the Load Balancing Topology, simply follow the same steps as when you created the Fire Wall Topology. [[BR]]
     270'''1. Use Omni to create the topology: [[BR]]'''
     271Download the RSPEC from http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/lb.rspec [[BR]]
     272Next, we need to create this experiment using the RSPEC file: [[BR]]
     273  '''Step 1. Create slice (use a unique name for your slice): Here I am using OpenFlowLB'''
     274{{{
     275omni.py createslice OpenFlowLB
     276}}}
     277  '''Step 2. Renew Slice (to make sure that your reservation does not expire before you finished your experiment, renew the slice to a specific time):'''
     278{{{
     279omni.py renewslice OpenFlowLB 20130521
     280}}}
     281  '''Step 3. Create Sliver using lb.rspec:'''
     282{{{
     283omni.py createsliver -a pg-utah OpenFlowLB lb.rspec
     284}}}
     285  Again, you can use the following command to show the reserved nodes as well as ways to login:
     286{{{
     287readyToLogin.py OpenFlowLB -a pg-utah
     288}}}
     289  When the nodes are not ready, the status will be `notready` or `changing`. In this case, you simply have to wait then try the above command again. [[BR]]
     290  Otherwise, the result is something like the following:
