OSC Project roundup:

News from OSC TOC & OSFG & RSAC calls last week

OAM (Martin Skorupski)

NONRTRIC (John Keeney (Ericsson EST))

  • Working hard on Integrated SMO deployment
    • Some questions/discussion about configuring O1 events (e.g. FM, device registration) 
      • Needed to get O1-CM registration working - so not auto-mounting in SDNC.
      • Would be good to align topics/config/namespaces etc.
    • First version nearly ready for testing.
      • Working hard on Nephio/ONAP/OSC co-location. 
      • Needs alot of resources - happy to see winlab machines coming on line.
      • Still have a networking issue between nephio control cluster (native k8s) & nephio workload clusters (kind k8s) to deploy OAI nodes
      • Issue with OAI CM changes not working - Diagnosis Ongoing.
      • Next steps will include AI/ML platform integration
        • To support ML inference service LCM via AIMLFW (as well as rApp manager)
        • To help demonstrate training & model management etc too
    • Should work with Alex Stancu to have some observable configuration change possible in simulator - but needs to be designed.
  • Struggling with AIMLFW Model-Management-Service - seems to be returning 200 code - but model is still not present in modelservice
    • Saul Gill subhash Would be good to share logs & diagnose a bit more. (LeoFS issue?)
      Will work-around for now. 
    • Entire AIMLFW is quite large & hard to get running on same cluster as rest of SMO. Will try again in later weeks. 
  • Still working on sample rApp - limited functionality - just a requirement driver for now.

  • JIRA

SIM (Alex Stancu)

  • Working away on integration & Hybrid O-RU (working on demos with OAI & Benetel(?) RU)
    • Driven by TIFG use case defn (JSON based)
    • Nearly to ready to demo

AI/ML platform project (subhash)

SMO (Seshu Kumar Mudiganti)

vDTF event this week:

Accessing InfluxDB from rApp (Aya Kamal Elbakly)

  • DME?
    • John Keeney (Ericsson EST) Should be DME, DB/query is not currently supported in out ICS/DME solution
      • ICS/DME is currently focusing on  event-based/streamed.
    • Current best way - but not the correct way - is to access the InfluxDBs REST api as a service consumer (rather than a data consumer)
    • Would be good to extend DME to support this - but may take time/resources.

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

  • No update this week - but working away on this.
  • From previous weeks:
    • 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
