    192 This sections shows you how to determine the site specific !OpenFlow RSpec details by walking through the information gathering process. To determine which !OpenFlow resources to use, go to the [http://groups.geni.net/geni/wiki/GeniAggregate GeniAggregate] page and select the !OpenFlow Aggregate links for BBN, Clemson and Wisconsin. Each of these !OpenFlow Aggregate pages contain a site diagram. The !OpenFlow site diagrams show ports, DPIDs, and hosts mapping for the site's !OpenFlow switch.  In addition to the information from the !OpenFlow site diagram, !OpenFlow groups rules must defined for each site to handle traffic for the hosts.  Each site RSpec will include a group definition for the network that looks as follows:

     208For a detailed look at OpenFlow configuration parameters, see the [http://groups.geni.net/geni/wiki/HowTo/WriteOFv3Rspecs/Spec OF V3 RSpec] page. On this page you will also find the list of available [http://groups.geni.net/geni/wiki/HowTo/WriteOFv3Rspecs/Spec#Filterelements packet header fields] that can be used to filter the OpenFlow traffic.
