    • More Release Planning

• OSFG:

    • Ready for review

NONRTRIC (@John Keeney (Ericsson EST))

• OSC NONRTRIC: Release J

• Continuing tasks as mentioned previous weeks:

  • Kicking off Release preparation

    • Hopefully we will be on time for ONAP New Dehli & OSC J-Release

  • Continue work our new Service Manager function

    • Improving Documentation & deployment scripts etc

    • Lots still to do! Backlog will continue into next release

  • Continue work on rApp Manager - as a focal point for tying together alot of other existing activities

    • Working on some sample rApps. e.g. See Release J: Simple rApp using Hello World Microservice

    • Working on SME & DME integration & improvements

  • Continue maturing the A1-Policy Controller function (ref ONAP) - including a potential new NBI (v3) to achieve R1 alignment

    • Current API will be maintained but deprecated for several releases to come.

    • Making slow but steady progress.

      • First version of R1 API implemented

      • Lots of work on testing & benchmarking & documentation

  • Still need to get working on a proper A1-Policy Integration test with OSC near-RT-RIC (A1 Mediator)

    • No update from near-RT-RIC team

  • Also working on REST tracing in A1-Policy functions (currently in ONAP)

  • Will need to de-prioritise many of the older less-used NONRTRIC functions - we welcome others in the community to help take these on if interested.

    • Need to study how/if we can achieve R1-DME alignment. Specs continue to diverge from our implementation - with alot of effort need to align.  We welcome contributors to help here.

AI/ML platform project (@subhash )

• Minutes & Meeting: Meeting notes

• Calendar: https://lists.o-ran-sc.org/g/main/calendar

• @subhash 

  • Integrated Pipeline Mnagement is not ready yet - will move to next release

  • Upgrading platform

    • K8s → 1.28

    • Trying to remove docker dependencies

  • Can we start using NONRTRIC Service Manager to expose AI/ML Platform functions?

    • Yes. The Service Manager is now enabled as part of the smo-install and nonrtric-install charts in it/dep.

    • We can add those endpoints AI/ML services as part of a bootstrap process, or add them during smo-install scripts, or can be added as part of AI/ML framework install scripts/charts.

    • Currently there is no enforcement of service exposure/access - but we want to use Service Manager (R1-SME) as the 'right way' to expose services to rApps and enable rApps to get access to them.

    • Currently doesn't matter if service is in a different cluster - later may need to create a tunnel or inter-cluster mesh to enforce exposure - but OK for now.

    • @John Keeney (Ericsson EST) will forward some links to @subhash, and hopefully in the next few days we'll have examples of existing services being added into the Service Manager registry as SMO start-up time.

    • @John Keeney (Ericsson EST) & @subhash Will work on some rApp use cases for next release that use training.

Questions / Comments / AOB:

• Updates/Questions in NONRTRIC @guru raja 

  • How to use DMaaP adapter for Bulk PM

    • @John Keeney (Ericsson EST) : Don't. Please use the RAN-PM functions which are much more functional & specific for bulk-PM.

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

    • RANPM charts are not yet integrated into smo-install charts

  • Integratin between SME & Keycloak

    • Current integration between CAPIF & Keycloak is not the correct way for rApps.

    • Hope to work on this (including exposure enforcement) in furhter releases - but resourcing is not certain yet. May need to wait for community engagement here to help out.
