    21 ''' Using Omni to get physical PCs from ProtoGENI:''' [[BR]]
    22 '''0. Get account: (Ignore this if you already have one) [[BR]]'''
    23 Go to [https://www.pgeni.gpolab.bbn.com/reqaccount.php3 Request_GENI_Account] for an emulab account and to join a GENI project.[[BR]]
    24 Apparently 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]]
    27 Here is a very good tutorial on setting up Omni environment: [http://groups.geni.net/geni/wiki/GENIExperimenter/Tutorials/HelloOmni HelloOmni] [[BR]]
    28 Simply follow the tutorial to set up Omni.

    3022= Create an Experimental Topology for Firewall with OpenFlow =
    31 '''1. Use Omni to create the topology: [[BR]]'''
    32 Download the RSPEC from http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/fw.rspec [[BR]]
    33 Next, we need to create this experiment using the RSPEC file: [[BR]]
    34   '''Step 1. Create slice (use a unique name for your slice):'''
    35 {{{
    36 omni.py createslice <slice name>
    37 }}}
    38   Output should be something like the following (here I am using 'OpenFlowFW' as the sample slice name):

     25  OR, follow the tutorial on [http://www.protogeni.net/wiki/FlackTutorial FlackTutorial] to create the topology using Flack interface
     26  - 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.
     27 - 3. Log onto the reserved nodes following instructions here: [http://groups.geni.net/geni/wiki/HowTo/LoginToNodes LoginToNodes]

    265 OK. After this point, we are ready to log on to the nodes and do the OpenFlow FireWall experiments! :-) [[BR]]

     33= Create an Experimental Topology for LoadBalancing with OpenFlow =
     34 - 1. Download the RSPEC from http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/openflow-loadbalancer-pc.rspec
     35 - 2. Follow the tutorial on [http://groups.geni.net/geni/wiki/GENIExperimenter/Tutorials/HelloOmni HelloOmni] to create the topology using openflow-loadbalancer-pc.rspec on ProtoGENI or InstaGENI [[BR]]
     36  OR, follow the tutorial on [http://www.protogeni.net/wiki/FlackTutorial FlackTutorial] to create the topology using Flack interface
     37  - 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.
     38 - 3. Log onto the reserved nodes following instructions here: [http://groups.geni.net/geni/wiki/HowTo/LoginToNodes LoginToNodes]
     39Done.

    273 = Create an Experimental Topology for LoadBalancing with OpenFlow =
    274 To create the Load Balancing Topology, simply follow the same steps as when you created the Fire Wall Topology. [[BR]]
    275 '''1. Use Omni to create the topology: [[BR]]'''
    276 Download the RSPEC from http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/lb.rspec [[BR]]
    277 Next, we need to create this experiment using the RSPEC file: [[BR]]
    278   '''Step 1. Create slice (use a unique name for your slice): Here I am using OpenFlowLB'''
    279 {{{
    280 omni.py createslice OpenFlowLB
    281 }}}
    282   '''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):'''
    283 {{{
    284 omni.py renewslice OpenFlowLB 20130521
    285 }}}
    286   '''Step 3. Create Sliver using lb.rspec:'''
    287 {{{
    288 omni.py createsliver -a pg-utah OpenFlowLB lb.rspec
    289 }}}
    290   Again, you can use the following command to show the reserved nodes as well as ways to login:
    291 {{{
    292 readyToLogin.py OpenFlowLB -a pg-utah
    293 }}}
    294   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]]
    295   Otherwise, the result is something like the following:
