• Agenda bashing

• Model Proposals
  
  

  • ETSI support for CNF model

    • R9 DM proposal: https://lf-onap.atlassian.net/wiki/pages/viewpage.action?pageId=16463007

      • 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

    • Updates：

      • Fred presents the latest progress: a wiki page on IFA011 v4.2.1 changes, ETSI IFA011 v4.2.1 Changes to ONAP Resource Model.

      • intention: update from v4.1.1 to v4.2.1

        • adding of VipCpdProfile, VipCpLevel, LcmCoordinationActionMapping classes, and related changes

        • introducing vnfdExtInvariantId at the vnfd

        • add two attributes in VipCpd: intVirtualLinkDesc, dedicatedIpAddress

        • name change of volumeTemplate → perVnfcInstance (in virtualStorageDesc)

      • papyrus changes already submitted by Fred

  • ASD model

    • Proposal: Application Service Descriptor (ASD) onboarding IM

    • Plan for the PoC: Application Package Onboarding to SDC

  • 5G service / CPS model

  • Reverse engineering

    • Jacqueline presents the current work on reverse engineering based on the simplified k8s resource proposal

    • the diagram shows the model of vf-module, tenants, etc. and their relationship with K8sResource class

    • next step:

      • Jacqueline will modify the diagram to better show the comparison between K8sResource and vserver classes

      • Xu will invite Fred to join the discussion

  • Topology model

    • Proposal: https://lf-onap.atlassian.net/wiki/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
      
      

      • inspired by TAPI model to add "link", "connection" classes

      • looking at ORAN use cases and see if the models can fulfill the requirements

      • TAPI presentation may be found here: otcc2019.KS.002_TAPI_Concepts_Topology_Connectivity.pptx

    • Latest updates:

      • comment: remove ManagedReference to simplify the model

      • Open
