    182182The OF RSpecs are used to request resources at each site's !OpenFlow Aggregate Manager.  This will result in your resource request being imported into the Opt-In manager, where an Administrator must approve your request for resources. Currently requesting OF resources for the sites in the experiment does not require OF setup for the Network Core path; the default handling will allow OF traffic.  This is expected to change.
    183183
    184 
    185184The OF RSpec defines a flowspace for each OF rule for your traffic sliver.  Following are example OF RSpecs that could be used to reserve the flowspaces needed for each of the generic 3 node scenario in this page. The scenario uses 3 OF Aggregate Managers (one per site) and one OF Controller at Site 1 for all sites.  The example RSpecs are for each of the 3 OF AM and assume that the flowspace is based on traffic type and port (TCP port 9080 and 9082).

    244 Using the RSpec that defines the required OF flowspace, you can now request OF resources with Omni. First create a slice using your GPO Clearinghouse credentials as defined in the omni_config. Note that the slice name should be meaningful to you:
    245 {{{
    246 $ ./src/omni.py createslice ln_OF_slice
    247 INFO:omni:Loading config file omni_config
    248 INFO:omni:Using control framework pgeni

    253   Options as run:
    254                 configfile: omni_config
    255                 framework: pgeni
    256                 native: True
    257 
    258   Args: createslice ln_OF_slice
    259 
    260   Result Summary: Created slice with Name ln_OF_slice, URN urn:publicid:IDN+pgeni.gpolab.bbn.com+slice+ln_OF_slice, Expiration 2011-06-16 19:46:49
    261  
    262 INFO:omni: ============================================================
    263 }}}
    264 
    265 Then create a sliver for each resource aggregate.  In this example there are 3 OF aggregates (one per site) and 3 compute resource aggregates (1 PG & 2 MyPLC), which maps to creating 6 slivers, and the following commands are executed:
    266 {{{
    267  $ ./src/omni.py -a https://ofam1.site1.com:1443/openflow/gapi/ -o createsliver ln_OF_slice OF-site1.txt.rspec
    268  $ ./src/omni.py -a https://ofam2.site2.com:1443/openflow/gapi/ -o createsliver ln_OF_slice OF-site2.rspec
    269  $ ./src/omni.py -a https://ofam3.site3.com:1443/openflow/gapi/ -o createsliver ln_OF_slice OF-site3.rspec
    270  $ ./src/omni.py -a https://www.emulab.net/protogeni/xmlrpc/am -o createsliver ln_OF_slice emulab-site2.rspec
    271  $ ./src/omni.py -a http://myplc.site1.com:12346 -o createsliver ln_OF_slice myplc-site1.rspec
    272  $ ./src/omni.py -a http://myplc.site3.com:12346 -o createsliver ln_OF_slice myplc-site3.rspec
    273 }}}
    274 
    275 ^^ Note: Examples that detailed rspec creation examples for the PG and MyPLC resource aggregates can be found in the other non-OF [wiki:GENIExperimenter/ExperimentExample experiment] example. ^^
     210Using the RSpecs that define the required OF flowspace, you can now request OF resources with Omni. First create a slice using your GPO Clearinghouse credentials as defined in the omni_config. Note that the slice name should be meaningful to you and then create a sliver for each resource aggregate.  In this example there are 4 OF aggregates (one per site plus one for the GENI core) and 3 compute resource aggregates (1 PG & 2 MyPLC), which maps to creating 7 slivers, and the following commands are executed:
