  • https://lf-o-ran-sc.atlassian.net/wiki/download/attachments/351698946/INT-OSC_E2E_Integration_Usecase_Rel_L_20250319.pptx?api=v2 
    • GPU? For training? - Depends on use case. 
  • subhash Want to add training as part use case
    
    • Want to train & Model Discovery & model LCM via AIMLFW functions.
    • Will discuss with NONRTRIC team about rApp LCM vs rApp LCM
      • e.g. how will rApp reference ML model from AIMLFW model deployment functions ... needs interaction to coordinate.
      • ref O-RAN APIs for model management & model deployment.
    • Martin Skorupski Difficult to have training with sample/simulated data.
      
      • Use lab deployments? Hard to do & will take time.
• Will discuss more with fransiscus bimo during RSAC 

OAM (Martin Skorupski)

• No update this week:
• See previous weeks:
  
  • Discussed current backlog:
    
    • OAM-429 - Getting issue details... STATUS
    • Creating a new sprint plan
  • Working on integrated docker-compose based deployment
    
    • https://gerrit.o-ran-sc.org/r/gitweb?p=oam.git;a=tree;f=solution

NONRTRIC (John Keeney (Ericsson EST))

• Guru & Deena: Any plans to develop specific rApps - e.g. Anomaly detection:
  
  • John Keeney (Ericsson EST) Not really. Have some sample rApps - and will build a few more - but not much complete/innovative rApps planned.
    
    • Community rApp contributions are welcome. Ref also topic below from Sunil & Karthikeyan
  • Anomaly detection - no plan - but plenty of generic anomaly-detection solutions, & reuse sample rApps to 'rApp-ify' the solution.
  • See above re Energy Saving use case - reusing existing rApp logic
• See previous weeks:
  
  • Updating ONAP A1-Controller
    
    • https://gerrit.onap.org/r/q/project:ccsdk%25252Foran
    • https://lf-onap.atlassian.net/wiki/spaces/DW/pages/129957892/O-RAN+A1+Policies+in+ONAP+Paris
  • Working on SMO Deployment
    
    • Combined lots of existing charts - now working together (ONAP, NONRTRIC, RANPM, TEIV) 
      • Alot of work needed to have all previous deployments using same underlying common functions - esp Kafka.
      • Current work in progress : https://gerrit.o-ran-sc.org/r/c/it/dep/+/14289
      • Need to document this better - wiki page, Jira etc.
    • Will try add Nephio later
    • Need to examine to integrate AIMLFW charts https://gerrit.o-ran-sc.org/r/gitweb?p=aiml-fw%2Faimlfw-dep.git;a=summary 
    • Also need to consider how to include existing SMO project functions e.g. Tacker
    • Will Services be available outside (Sridhar Rao, Aravindhan Ayyanathan (Ericsson EST))? 
      • Inside cluster all services can now use FQDN - not node-ports.
      • Services should also be register in Service Exposure Manager to be used via API gateway & discoverable
      • Eventually services may be discoverable / exposed outside cluster - e.g. ref CAMARA etc.

  • ONAP A1 - Epic https://lf-onap.atlassian.net/browse/CCSDK-4071

rApps & packages

• Lets come back to this next week if possible: (Sridhar Rao)
  • Sridhar Rao Any chance of updating existing old/legacy rApps to current rApp format?
    
    • https://gerrit.o-ran-sc.org/r/admin/repos/q/filter:nonrtric/rapp
    • John Keeney (Ericsson EST) No current plan. Was planning to deprecate & remove.
    • Sridhar: Might be able to find some help for that
    • Note: Current rApp package is not spec compliant  - it is an internal format only (post onboarding) We eagerly await a standardised rApp format from O-RAN.

  • Would like to contribute to NONRTRIC
