OSC Project roundup:

News from OSC TOC & OSFG & RSAC calls last week

Proposal: "Predict future PRB demand per slice in 5G RAN Network" (Sunil N)

  • Sunil N presented some slides proposing a new use case & rApp for "PRB demand prediction - per slice"
    • Slides:
    • All: Looks great. Looking forward to getting stated.
    • rApp & deployment will be very similar to AIML rApp demos at 2024-10 O-RAN F2F Montreal 
    • Will start with dummy data. for training 
    • Will work with subhash for training etc & how to store trained model 
  • Action: John Keeney (Ericsson EST) to propose a new repo to store rApps 
    • larger/ongoing rApps may be promoted to own repo later
    • (Need to remove existing old/obsolete rApp from many years ago!)
  • Action: Sunil N Aim to create a wiki page for the use case, to store snippets, discussions etc for future users & other rApps developers
    • Also discuss on mailing list and/or slack as needed. (Slack invite)
  • Action: Sunil N & Martin Skorupski To briefly present & then track use case in RSAC. 

How to add PM data to InfluxDB (Demond Wael)

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

  • No update this week - but working away on this.
  • From last week:
    • Discussion End-to-End Integration
      • Good progress made on O1-PM - convert to file format & reuse existing RANPM functions → rApp
      • 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 

Accessing WINLAB resources: Ivan Seskar John Keeney (Ericsson EST) Aravindhan Ayyanathan (Ericsson EST)

  • John Keeney (Ericsson EST) & Aravindhan Ayyanathan (Ericsson EST) now have access 
  • Hopefully later in week will have a cluster of some machines in Lab
    • Ideally would like some ideas about how to structure deploy
      • e.g. into 2 deployments - for stable version & dev/scratch version
    • Needs some coordination
      • ... e.g. if you break it then fix it, or wipe & re-instate.
      • How often to auto-wipe/kill the deployments, etc.
    • lets see what is aviallable first, then we can discuss options.
