    160160Step 1. Collect listresources from all FOAM Aggregate.  The manifest RSpec details all resources at the aggregate, but does not provide any insight into whether they are available.
    161 Step 2. Review [http://groups.geni.net/geni/wiki/GeniAggregate GeniAggregate] to determine how each MyPLC host maps to the Site's OpenFlow switch.
    162 Determin addresses and ports.
    163 Step 3. Using guidelines from the [http://groups.geni.net/geni/wiki/HowTo/WriteOFv3Rspecs#WritingOpenFlowv3requestrspecs Writing OF V3 RSpec] page merge the information from step 1 and 2 to generate the request RSpecs.

     162Step 3. Define site specific OF Group rules.

    292 '' '''Step 3''' ''.  Define OF groups and merge with Switch details from step 2:

    294 Use the request template in the [http://groups.geni.net/geni/wiki/HowTo/WriteOFv3Rspecs#WritingOpenFlowv3requestrspecs Writing OF V3 Request RSpecs]
     292'' '''Step 3''' ''.  Define OF groups rules:
     293
     294Each of the site will need to define OF rules for handling site traffic for the hosts.  Each site Rspec will include:
     295
     296{{{
     297    <openflow:match>
     298      <openflow:use-group name="group-name" />
     299      <openflow:packet>

     303      </openflow:packet>
     304    </openflow:match>
     305}}}
     306Note the ''group-name'' above will be replace by the actual group name values defined in the previous step. Here is a summary of groups defined in Step 2:
     307   * BBN Site: bbn-1750-nodes, bbn-1750-3715
     308   * Clemson site: clemson-1750-3715
     309   * Wisconsin group name=wisconsin-nodes-1750, wisconsin-1750-3715
    295310
    296311'' '''Step 4''' ''  Insert request details into OF V3 RSpec template.
    297312
    298 {{{
     313Use the request template for OF V3 Request RSpecs shown below to create the RSpecs for the BBN, Clemson and Wisconsin OF aggregates:
     314
     315{{{
     316#xml
    299317<?xml version="1.1" encoding="UTF-8"?>

     328      <openflow:controller url="tcp:example.geni.net:9933" type="primary" />
     329
    310330

    314334</rspec>
    315335}}}
     336
     337For the above template:
     338 * Modify the "openflow:sliver" line to replace the "user@geni.net" with your valid email address, and update the sliver description.
     339 * Update the "openflow:controller" line to include your controller information.
     340
     341You may now combine the modified template with each of the Site specific openflow details from step 2 and 3.
     342
     343This will result in the following final OF RSpecs:
