• Update
  • CPS - how the code can be used?
    • modification of yang (subset for needed use case) to be applied and
    • other configurations (dataset as json)
    • yangs can be also injected based on SDNC (NF yangs - in this case unmodified yangs)
    • manual steps vs automation
    • CPS demo:  2023-04-04 Meeting notes - Developer Wiki - Confluence (onap.org)

    • How does CPS get yang model?
      • SDNC Adapter: https://wiki.onap.org/display/DW/CPS-NCMP+-+DMI+-+SDNC+Request+and+Response+Mapping
        • Vishal's teams are looking to check if this is still all up to date.
      • Unclear if this is two-way (read/write config) or one way (read-only) with CM performed direct to SDNC.

• Ref: RSAC meeting 20/Sep - Slides & video @ RSAC Meetings 
• Still very unclear how it/dep deployment works & if it is maintained.
• Work from Taiwan Lab should / could be reusable hopefully.
• Meeting with ONAP OOM team last week to iron out technicalities of deploying ONAP functions
  • https://lists.onap.org/g/onap-meetings/viewevent?repeatid=31908&eventid=2003085&calstart=2023-10-04 
    • Wednesday, October 4th, 2023
      2:00pm to 3:00pm (UTC) Coordinated Universal Time
      https://zoom.us/j/96113493781?pwd=cER3aHgvZ1MrNmtXZVV1K0hmQjhnQT09
  • Detailed discussion on deployment etc, version without AAF,  Byung-Woo Jun Andreas, Louis Lie, N.K. Shankaranarayanan & others
    • Discussions & Emails currently ongoing.
  • Use case? : None apparent yet - focus on deployability & DI/CD as a use case.
• There have been updates since OAM function version in it/dep / ONAP worked
  • e.g. VES collector needs to be built (3gpp)
  • e.g. OAM gateway (sdnc, keycloak, dmaap, ves collector are now behind gateway for ease of addressing)
• SIM / topology ... still pretty similar - but very use case specific
• NONRTRIC ... Charts in it-dep/nontric directory are up to date. Charts/configurations in it-dep/smo-intall are a little dated, but not too bad.
• Main question is where does platform stop & use case start .. A lot of the charts/deployment is use case specific.

• PM flows
  • PM Streaming above as an example of SMOS mapped into WG10 SMO sketches/proposals
• Short update from last week:
  
  • Discussion continue in WG1 re AI-ML inclusion in flows.
  • Include service Orchestration function?
  • Include Service Assurance?
• Will come back to TOC this week Oct 12 
• Mapping work in O-RAN WG1 (Disaggregated SMO) to related opensource projects 
  • Strawman for architecture - driven by some candidate usecase flows.
  • Aim for alignment across projects and across diff specs.
  • Aim for common vocabulary etc.
• N.K. Shankaranarayanan working on slides now. See draft slides from previous weeks:
