Minutes:

  • Agenda bashing
    • reminder for filling R9 high level requirements: https://wiki.onap.org/display/DW/ONAP+R9+Modeling+High+Level+Requirements
      • new requirements may be added after more use case presentations
      • plan to review intent based networking model proposals next week
    • time change for modeling subcommittee call
      • Andy has discussed with Ben, and plan to not change the time for now, will have further discussion on modeling subcommittee call
  • Joint call with use case realization team
  • Model Proposals
    • ETSI support for CNF model
      • R9 DM proposal: https://wiki.onap.org/pages/viewpage.action?pageId=93011772
        • aligned with SOL001 v4.2.1, package format is still under discussion
        • will ask for approval after SOL001 v4.2.1 is stable
      • a proposal of updating the information model documentation is planned in R9
      • latest updates:
        • Thinh has presented the alternative package solution in the CNF taskforce call, could be discussed in future calls
        • CNF requirements collaboration pending discussions as well, could be discussed in this week's CNF taskforce call
    • 5G service / CPS model
    • PNF instance model
      • reverse engineering
        • gendoc has been created and is presented by Jacqueline
          • the document is useful because of easier understanding
          • for example, the description shows there are several attributes/models marked not working for now ("not correctly populated", etc.)
        • question is which content to focus for now (considering the document has 500+ pages)
          • Jacqueline prefer to start with PNF model (as originally proposed)
          • Andy agrees to start with PNF, and can further look at topology related items
          • Xu suggests to start with PNF, and then look at current model proposal related topics
        • may need to have a seperate directory to host the AAI models, to avoid potential non-compatible issue of papyrus
        • Andy suggests to mark all the models in experimental stereotype for now
        • Jacqueline will help upload the gendoc document
    • Topology model
      • Proposal: https://wiki.onap.org/display/DW/Abstract+Topology+Model
        • Martin will update the models with the IM sketch
      • Model Sketch: https://wiki.onap.org/display/DW/Proposed+Topology+IM+Sketch
      • Andy has helped to create a high level requirement for the topology model
        • expecting ORAN to provide relavent use cases
        • Martin and Andy are aware of the different views of topology model presented last week by Cagatay
        • mainly triggered by ORAN WG10, also related to WG1's slicing use case, etc.
        • how to model different layers, physical, logical topology, etc.? current methodology is using UML/papyrus to capture the models
      • Latest updates:
        • Martin is working on the TAPI model, and has discussed with the SON use case team to receive feedback from them
  • Modeling Documentation
  • No labels
