    204204==== BBN !OpenFlow Aggregate ====
    205205
    206 To define the !OpenFlow request RSpec for the BBN site we need to consider the compute resource selected, which is the MyPLC node navis.gpolab.bbn.com.  We then determine how the node is connected to the !OpenFlow switch, the Data Path IDentifier (DPID) for the switch, and then we determine the path required to connects to the network core OF 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:
     206To 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 OF 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:

    215215   * VLAN 1750 is mapped to the Core VLAN 3715 on ''poblano'' port 3.
    216216
    217 Note: The VLAN 1750 is used at every meso-scale site for MyPLC resources to access the back bone !OpenFlow VLANs. [[BR]]
    218217Note: For the BBN ''habanero'' OF switch *only*, you must add 24 to the physical port number to determine the port to use in the rspec. The host navis.bbn.com is on port 32 (+24=56),  which means your rspec will use  port ''56''  and port 47 (+24=71) maps to ''71'' to get to poblano.  The syntax for each of these can be "borrowed" from the listresources associated to each DPID. 
    219218
    220 Now we have all the information needed to define the BBN OF resource request RSpec. These are lines that define the ports on habanero:

    360 To define the NLR OF RSpec review the [http://groups.geni.net/geni/wiki/SiteNlr#OpenFlow OpenFlow DPIDs] table for the core in the [http://groups.geni.net/geni/wiki/SiteNlr National LambaRail] GENI page. From the table you can see the DPIDs for OF VLAN 3715 for NLR. You may choose to use only the two core sites (Chicago and Atlanta) associated with the three sites in this experiment, but for simplicity you may choose to define all DPIDs in the NLR Core for VLAN 3715, which is how this example is shown:
