  • Minutes: RSAC Meeting notes
  • Energy saving use case:
    • Discussion End-to-End Integration
      • see below ...

RSAC Energy Saving use case  (rApps & AI/ML)

• Discussion End-to-End Integration
  • Good progress made on O1-PM - convert to file format & reuse existing RANPM functions → rApp
    • Note: RANPM snapshot images have timed out. !
      
      • John Keeney (Ericsson EST) & Aravindhan Ayyanathan (Ericsson EST) - Recreate the snapshots. Good for another 30 days
      • Make sure release happens before 30 days & update charts in it/dep
  • O1-CM: 
    • When integrated SMO deployment is ready rApp should be able to use NCMP as a wrapper for RestConf → SDNC/ODL
    • Exposed via SME to rApp
  • Topology:
    
    • Martin Skorupski will create a topology/deployment model - which can then be processed by TEIV to bootstrap the TEIV topology.
      
      • Will help pre-populate the topology & add links etc - where adapters do not yet exist.
    • Also TEIV adapter nearly complete; to poll NCMP/SDNC to populate TEIV-OAM data of ODUs/OCU/ODUCell/OCUCell
      • Available for rApp to query which DU/Cells to target for Energy saving rather than hard coding
    • TEIV can then be queried by ESrApp to get IDs etc & containment info needed - rather than hardcoding in rApp logic
  • AIML
    • John Keeney (Ericsson EST) & subhash to discuss: 
      • How & when training happens, & where trained model is stored
      • How AIMLFW is deployed as part of SMO
      • How rApps ML model is deployed as an Inference service for rApp to use (KServe) 
  • rApps & xApp
    • bimo fransiscus asisi to advise on where the current Apps are - to help identify how to extend for deployment. 
  • VES collector in SMO
    • Can change configuration in integrated SMO (via configmaps - TBC), but need to download & make 3GPP schema files available somehow.
      
      • May need to add a custom step to pull these files during SMO setup. (Similar for other functions where spec downloads might be required before use)
  • Will discuss more with fransiscus bimo during RSAC 

OAM (Martin Skorupski)

• No update this week:
• Wants to find time to further discuss PM streaming with Sridhar Rao
• 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

• JIRA:
  

  • OAM-429 - Getting issue details... STATUS

NONRTRIC (John Keeney (Ericsson EST))

• Working hard on Integrated SMO deployment
  • First version nearly ready for testing.
• 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.

AI/ML platform project (subhash)

• Minutes & Meeting: Meeting notes

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

• Still working on Reusable components for reuse in usecases to avoid having to had ad-hoc solution for each use case. (Dynamic Pipeline)

SMO (Seshu Kumar Mudiganti)

• Meeting notes Meeting notes
• No specific update

• Topology & Inventory: (John Keeney (Ericsson EST) :

  • Lots of small updates in K-Release & ongoing. Focus on ingestion adapters in this release.

rApps & packages

• Lets come back to this next week if possible: (Sridhar Rao)
  • Existing / old rApps (e.g. nonrtric/rapp/orufhrecovery & nonrtric/rapp/ransliceassurance)
    • Very old & cannot be used with current rApp Manager. e.g. - wrong format, no DME/SME supports, no LCM
    • Difficult, but possible, to upgrade to newer rApp format. may need to be deprecated & archived otherwise.
  • See previous info: 
    
    • 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. 

How to add PM data to InfluxDB (Demond Wael)

• Difficult to inject data into RANPM pipeline to have it appear in InfluxDB
• John Keeney (Ericsson EST) Avoid trying to use internal interfaces/formats/topics in the RANPM flow
  
  • Use 3GPP XML files, hosted in some FTP/HTTP server (HTTP server provided), then send a VES event to VES collector (with the path/filename to the new file)
    • Toolchain does all necessary XML→JSON translation, filtering etc, then inject into InfluxDB)
  • Ref: https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-ranpm/en/latest/overview.html#data-flow 
  • latest snapshot version of RANPM functions support 3GPP file-ready event format & latest NR PM data files. Older (Release K) versions only support older VES-format file-ready events & older 4G PM data file.
    
    • Older version demo: 2023-08-22 Meeting notes - Joint OAM / NONRTRIC / SIM Community meeting#20230822MeetingnotesJointOAM/NONRTRIC/SIMCommunitymeeting-DemoNONRTRICRANPMFunction-Dockercompose&Scripts()

A Topic for next week

• Hello again from Sunil N (Samsung) (Welcome )
  
  • Hopes to discuss possible NONRTRIC contribution next week.
