NONRTRIC (@John Keeney (Ericsson EST))

• Demo: "LCM of ASD-based CNFs using ONAP CNFM function in Standalone mode" @Aravindhan Ayyanathan 

  • At last weeks RSAC committee Meeting (17 May 2023)

  • Demonstrate ASD-based LCM for CNFs using a cut-down version of the CNFM function originally from the ONAP SO project. The function can be used in standalone mode without the need for the rest of SO, A&AI or SDC.

• Demo: "CAPIF for Service Registration & Service Discovery" @Yennifer Chacon 

  • At last weeks RSAC committee Meeting (17 May 2023)

  • Demonstrate Demo/Discussion of CAPIF-based Service registry/discovery. The 3GPP CAPIF approach seems to be gaining traction as a basis for R1-SME, and we would like to show the progress we have made with our implementation.

• Working on improving documentation - especially for RAN PM functions:

  • https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-ranpm/en/latest/

• Making some initial progress on consolidated rApp manager ... but just starting still

• Experimenting with using Avro for PM data serialization ...

• Will try to expedite release processes for ONAP & OSC due to teams vacation & availability plans

• Previous weeks:
  
  

  • Consolidating PM data exposure in new repo for RAN PM functions

    • https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric%2Fplt%2Franpm.git;a=summary

    • Secured/Sandbox execution environment

    • Controlled access & exposure of service to/from rApps

  • (R1) Data Management & Exposure

    • File-based PM data → InfluxDB

    • Previous focus on PM data - but will extend to other use cases too

    • Aim to work with AIML project for Training (and Inference ?) data access

  • rApp Management

    • Built on ONAP “Automation Composition” model & platform to implement rApp use cases

      • Inference Services in rApps

    • A1 Spec evolution

    • A1-Policy work in ONAP (continues in ONAP London) - candidate for R1-A1(P)

    • A1-EI management as part of DME - candidate for how to include A1-EI in R1-DME

  • Sample use cases (rApps)

ONAP/OSC Usecases(@N.K. Shankaranarayanan)

• SON Usecase

  • Moving towards release prepartation

  • NETSIM in ONAP needs some update (Honeycomb not available?

ONAP/OSC Alignment Usecase proposal for ONAP Montreal(@N.K. Shankaranarayanan)

• As discussed last week here.

• Discussed at ONAP TSC call last week: https://wiki.onap.org/display/Meetings/TSC+2023-05-18

  • Lots of interest in ONAP TSC

  • Emails to OSC TOC/RSAC chairs. Lots of interest

• "ONAP/OSC SMO Automation use case." (Umbrella of use cases )

• Use cases will need an rApp

  • Could align with ONAP ACM team to show 'hello-world' type rApps/compositions to show the end-to-end nature.

    • rApps would have very limited intelligence or functionality - little more than stubs.

• The word "Use-case" is very overloaded

  • In OSC we are aiming more for an "Integration Demonstrator"  (use-case may not be the best word)

  • In ONAP 'use-case' is good (Integration has different connotations in ONAP)

Questions / Comments / AOB:

• Nothing additional this week.
