Some answer about modeling and mappings can be found here

Working Assumption to be proven about figure 7-21 – UML model diagram – CdSpecificView

  • PtpDomainConstraint_Pac is a model OUTSIDE of the device (control-construct)
    • There is the first expectation that all attributes are already in the LTP(Sync) and CLOCK object class.
  • NeSync_Pac
    • under the assumption that "Ne..." mean "NetworkElement..." the "NeSync_Pac" could be called "ControlConstructSync_Pac" and attached to the ControlConstruct itself

CoreModel

  • ControlConstruct
    • LTP
      • - e-m-b-e-d-d-e-d-C-l-o-c-k- (ref to a clock)
        covered by UML-to-YANG tool pruning and refactoring. 
      • target
        • list embeddedClock → goes to leaf-list with type leafref with path /control-construct/collection-of-clocks/clock

Proposal

  • ControlConstruct
    • LTP
      • LP
        • synchPac
          • ref-to-clock


AI: How to deal with refactoring of the CoreModel to get all references from SyncModel to ControlContruct. 

 - Answer: as in the past - the UML2YANG tool does the corection correction to reference the core-model-1-4.yang.


Modeling of NeSnyc-Pac according to the working assumption above (some smaller changes expected)

Looks like there are different versions with similar but different content.

Relation between planning and actual data from the network


@Andreas Lattoch

Quick synch from last week

  • connector types to be standardized
  • work in progress - to be continued
  • Current work bases on the "EquipmentModel"

updated proposal

  • holders identified by a, c, ...
  • connectors identified by 0, 1, ...

Example

subrack-slot-port - 1-2-3 goes to a.b.3

Pre- Discussion happened yesterday 

  • info send by Thorsten on Monday 2021-05-177
  • in addition Thorsten will send the "background discussion slide"....

Mediator Instance Manager 

  • What is the protocol? NETCONF or REST or RESTCONF or ...
    • Working Assumption:  not decided
    • SIAE would like to decide based on efforts after analysis. 
    • UML include the "service" - but not the operational and maintenance layer
    • YAML (OpenAPI3) → UML (papyrus) → YANG →
