    1111== 1. Substrate description model == 
    1212This is the substrate-specific detailed resource and topology model that is used by the owner of the substrate to describe its physical resources including edge (compute and storage) resource and network topology. It also describes the domain services exposed to the broker(s).

     13 '''a. Domain Service Description ([source:orca/trunk/network/src/main/resources/orca/network/schema/domain.owl domain.owl])'''  
    1414      The class hierarchy is defined in the diagram below. A substrate (domain) is defined as a collection of !PoPs. Each PoP, with a geographical location, is a collection of network devices and/or data center. The Class domain also has a property ''!NetworkService'' which could have a number of ''!ServiceElement''. This information would be passed to the advertisement RDF. 
    1515             * !AccessMethod: e.g. ORCAActor, or GENI AM API.

    5050== 2. Substrate delegation model == 
     
    7373Current implementation is based on a two-level resource allocation and stitching model: the controller and the broker policies do the cross-site path/topology computation/embedding and resource allocation based on the abstract delegation models. Upon reservation redemption, each site implements its own control policy to do intra-site sub-path/topology computation/embedding and resource allocation based on the its substrate RDF model. The whole process is based on a reservation dependency workflow.
