 For experimenters who desire control over the network switching fabric in their slices, !OpenFlow provides increased flexibility.  Your experiment will incorporate an !OpenFlow controller. Many experimenters use existing controller code as-is, some use controllers with relatively simple modifications, and some experimenters have written their own controller.  The GPO is available to help design your controller and plan your experiment configuration.  Feel free to contact us at [mailto:help@geni.net].
 
-The example captured in this page uses credentials from pgeni.gpolab.bbn.com, the GPO ProtoGENI Clearinghouse, to set up an experiment that includes 3 meso-scale OpenFlow sites (1 PG at BBN and 2 MyPLC nodes at XXX and YYY). This example shows a NOX !OpenFlow Controller running on a slice resource that is available and accessible to the FOAM instances. In this scenario, two sites are Web Servers and 3 are clients, as shown in the diagram below:

 This example assumes that GENI credentials have been set up as detailed in the [wiki:HowToUseOmni#a1.GetGENICredentials GENI Credentials] section of the [wiki:HowToUseOmni Omni how-to] page.
 
-The settings as defined in the [wiki:GENIExperimenter/ExperimentExample#OmniConfiguration Omni Configuration] section of the non-OF Omni how-to example will work for this experiment.  The credentials from the GPO Clearinghouse allow access to the FOAM at each site and in the GENI Core.

 == Determine Resources ==
 
-An !OpenFlow RSpec must be defined for each of the 3 sites to get access to the OF resources.  The content of the OF RSpec depends on the type OF resources that you may need.  You may need to define an RSpec using any of the following:
+Each of the 3 sites will requires an !OpenFlow RSpec and a compute resource RSpec. To find out what resources are available use Omni tools to get a list of available resources. For a list of available aggregates see the [wiki:GeniAggregate GENI Aggregates] page.
+
+To set up the 3 site experiment on this page, the following Aggregate Managers were queried with omni to get a list of available resources:
+
+ 1. Clemson FOAM and MyPLC aggregates:
+{{{
+ ./src/omni.py -a https://foam.clemson.edu:3626/foam/gapi/1 listresources -o   # generates output file rspec-foam-clemson-edu-3626-foam-gapi-1.xml
+ ./src/omni.py -a  http://myplc.clemson.edu:12346/ listresources -o            # generates rspec-myplc-clemson-edu-12346-.xml
+}}}
+ 2. Wisconsin FOAM and MyPLC aggregates:
+{{{
+ ./src/omni.py -a https://foam.wail.wisc.edu:3626/foam/gapi/1 listresources -o    # generates rspec-foam-wail-wisc-edu-3626-foam-gapi-1.xml
+ ./src/omni.py -a https://wings-openflow-1.wail.wisc.edu:12346/  listresources -o # rspec-wings-openflow-1-wail-wisc-edu-12346-.xml
+}}}
+ 3. BBN FOAM and PG aggregates:
+{{{
+ ./src/omni.py -a  http://www.pgeni.gpolab.bbn.com/protogeni/xmlrpc/am listresources -o # generates rspec-www-pgeni-gpolab-bbn-com-protogeni.xml
+ ./src/omni.py -a https://foam.gpolab.bbn.com:3626/foam/gapi/1 listresources -o         # generates rspec-foam-gpolab-bbn-com-3626-foam-gapi-1.xml
+}}}
+
+Note: Each of the omni command used the -o argument to get the listresources output to a file.  Each of the listresources output files are attached to this page.
+
+
+The content of the OF RSpec depends on the type OF resources that you may need.  You may need to define an RSpec using any of the following:
   * IP Addresses 
   * MAC Address
   * Data Path Identifier (DPID).
 
-To find out what OF resources are available from each of the FOAM sites, use Omni tools to get a list of available resources. For a list of available aggregates see the [wiki:GeniAggregate GENI Aggregates] page. Here is an example of listing resources advertised by  each of the sites in this experiment and in the GENI Core:
