    • Lets take a fairly simple ad-hoc approach to booking for now.

    • From last week:

      • Plan for 8 servers - will look something like this:

        • srv1.osc.cosmos-lab.org → ?? used by O-RAN-SC INT for Tacker

        • srv2.osc.cosmos-lab.org →?? Environment1 (K-Release: Stable)

        • srv3.osc.cosmos-lab.org→ ?? Environment1 (K-Release: Stable)

        • srv4.osc.cosmos-lab.org→ ?? Environment1 (K-Release: Stable)

        • srv5.osc.cosmos-lab.org→ ?? EnvironmentA (L-Release: Development)

        • srv6.osc.cosmos-lab.org→ ?? EnvironmentA (L-Release: Development)

        • srv7.osc.cosmos-lab.org→ ?? EnvironmentA (L-Release: Development)

        • srv8.osc.cosmos-lab.org→ ?? Experimental → wiped out very day at 00:00 UTC?

        • Example ssh config file

          Host o-ran-sc-gateway HostName gw.orbit-lab.org Host o-ran-sc-srv1 HostName srv1.osc.cosmos-lab.org ProxyJump gw.orbit-lab.org

      • Make sure to create profile & upload public key for Orbit:

        • Ref Ivan's talk at the last F2F 2025-02 O-RAN F2F Paris & Slides

        • https://www.orbit-lab.org/userManagement/register 

      • Connections will be via a jump-host.

  • 2025-06 O-RAN F2F Fukuoka 

    • Aim for a session on collaborative integration - based on work discussed / demoed at OAI workshop & OSFG workshop

      • @bimo fransiscus asisi @John Keeney (Ericsson EST) @Sridhar Rao @subhash @Alex Stancu @Martin Skorupski & all 

OAM (@Martin Skorupski)

• Working in Dashboard for PM values - from DB - based on IOSMCN integration - with @Alex Stancu

  • See OAM repo - Change by Ravi

    • Ref oam.git;a=tree;f=solution/smo/oam/pm - grafana 

• JIRA:

  • https://lf-o-ran-sc.atlassian.net/browse/OAM-429

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.

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)

• Working on dynamic pipeline / platform

• Integration & ES usecase

• Minutes & Meeting: Meeting notes

SMO (@Seshu Kumar Mudiganti)

• Meeting notes Meeting notes

• No specific update

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

  • See vDTF presentation next week (TEIV/NCMP/SDNC)

  • Will be integrated into SMO-install mentioned above

vDTF event this week:

• ONAP DTF DAYs 2025  

• https://linuxfoundation.regfox.com/onap-dtf-2025

  • See esp. talk on TEIV/NCMP/SDNC integration (@John Keeney (Ericsson EST), @Jeff van Dam, @Byung-Woo Jun)

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

      • Note: RANPM snapshot images have timed out. !

        • @John Keeney (Ericsson EST) & @Aravindhan Ayyanathan - 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
