    60 In the Meso-scale network a layer 3 experiment requires its own separate IP subnet in order to control all traffic without interfering with traffic from other experiments. At this point you need to request an IP subnet  from the gpo-infra@geni.net mail list. The request should also specify a duration.

    84 This experiment uses Omni V1.6.1 to set up the experiment. As a first step, the experimenter determines the available resources at each of the MyPLC Aggregate Managers.  Following are the omni commands issued to get the manifests for available compute resources:
    85 
    86  1. Clemson MyPLC aggregate:
    87 {{{
    88  ./src/omni.py -a  http://myplc.clemson.edu:12346/ listresources -o            # generates rspec-myplc-clemson-edu-12346-.xml
    89 }}}
    90  2. Wisconsin MyPLC aggregate:
    91 {{{
    92  ./src/omni.py -a https://wings-openflow-1.wail.wisc.edu:12346/  listresources -o # rspec-wings-openflow-1-wail-wisc-edu-12346-.xml
    93 }}}
    94  3. BBN MyPLC aggregates:
    95 {{{
    96  ./src/omni.py -a http://myplc.gpolab.bbn.com:12346/ listresources -o            # generates rspec-myplc-gpolab-bbn-com-12346-.xml
    97 }}}
    98 
    99 Each of the omni command above used the -o argument to get the listresources output to a file, all output files are attached to this page as a reference.  The Advertisement RSpec generated by the listresources are then reviewed to generate the request RSpecs to reserve the resources.  Following are the compute resources RSpec defined based on the output of the listresources commands above.

     156The MyPLC plnodes are pre-configured to use pre-defined addresses and MyPLC doesn't allow experimenters to change that configuration. When the experiment is running you will need to choose the appropriate interface for your experiment traffic.
