    285 To define the !OpenFlow request RSpec for the BBN site we need to consider the compute resource we selected, which is the MyPLC node navis.gpolab.bbn.com.  We then determine how the node navis is connected to the !OpenFlow switch, then we find the Data Path IDentifier (DPID) for the switch VLAN 1750 which is used at every meso-scale site for MyPLC resources to access the backbone !OpenFlow VLANs, and finally we determine the path required to connects to the network core !OpenFlow VLAN 3715.   All this information can be found in the [http://groups.geni.net/geni/wiki/GeniAggregate/GpoLabOpenFlow BBN OF Aggregate] diagram, which is shown below with the relevant BBN !OpenFlow request RSpec details highlighted:

    289289The BBN !OpenFlow Aggregate image above shows the information required for the !OpenFlow RSpec:
    290    * Host navis.bbn.com is connected to port name 32 of the !OpenFlow switch named ''habanero''
     290   * Host ''navis.bbn.com'' is connected to port name 32 of the !OpenFlow switch named ''habanero''
    291291   * !OpenFlow switch ''habanero'' has a DPID of ''06:d6:00:24:a8:c4:b9:00'' for VLAN 1750.
    292292   * !OpenFlow switch ''habanero'' uses port name 47 to connect to port name 20 on the !OpenFlow switch ''poblano''.
    … …  
    294294   * VLAN 1750 is mapped to the Core VLAN 3715 on ''poblano'' port name 3.
    295295
    296 The BBN ''habanero'' !OpenFlow switch diagram states that you must add 24 to the port name to determine the port number to use in the RSpec. You don not need to worry about this! The mapping  'port name' to 'port mapping' is now done for you by the FOAM aggregate. Simply look for the port names listed above in the listresources output and "borrow" the syntax from the listresources associated to each DPID.  Now we know the site specific information and can start to define the BBN !OpenFlow resource request RSpec details.

    362 To define the !OpenFlow RSpec for the Clemson site review the information in the [http://groups.geni.net/geni/wiki/GeniAggregate/ClemsonOpenFlow Clemson OF Aggregate] diagram.  The compute resource used is the MyPLC node  planetlab4.clemson.edu. The following image highlights the the information required from the Clemson !OpenFlow Aggregate site diagram:
