OSC Project roundup:

News from OSC TOC & OSFG calls last week

• TOC: https://lf-o-ran-sc.atlassian.net/wiki/display/TOC/#ORANSCTechnicalOversightCommittee(TOC)

  • Last week's TOC (Thursday):

    • New RSAC co-chair - Congrats @Martin Skorupski!

    • New PTL for INT project - Congrats @fransiscus bimo !

    • OSC will start using Slack - will pass on details when we know more.

      • https://jira.linuxfoundation.org/plugins/servlet/desk/portal/2/IT-26973 

    • OSC and ONAP wikis will move to a centrally located/hosed Confluence site (atlassian.net)

      • Possible issues:

        • Links will break, esp cross-site links (where full url is given - e.g. this meeting's minutes page urls: https://wiki.onap.org/pages/viewpage.action?pageId=231407794 & https://wiki.o-ran-sc.org/pages/viewpage.action?pageId=125043203)

        • User accounts need to be mapped or re-created on Atlassian cloud site - and people may already have accounts there that are difficult to map to LF-ID etc.

        • It is likely that recordings/ demos/ presentations / documents etc stored in current wiki may become unavailable?

      • Hopefully LF will be able to work around some of these issues.

  • This week's TOC (in 2 days):

    • No major topic planned yet (AFAIK)

• OSFG:

  • Cancelled this week.

  • Will discuss demos for next F2F.

    • Want more demos - similar to request from OSC TOC

    • Will look at several projects, e.g. OSC, SRSRAN, OAI, nephio, and lots of others

NONRTRIC (@John Keeney (Ericsson EST))

• A1-Controller NBI Issues:

  • WG2 R1 spec for Nov release changes from March version (not backwards-compatible)

    • May pull/remove the recent ONAP New Delhi & OSC J-Release versions of A1-Policy Management Service - which implements the Mar'24 version of the spec.

    • May move direct to Nov'24 version - currently been voted on in O-RAN Alliance WG2 as Maintenance-/ Bug-Fix-Release in next few weeks.

    • Do not want to support a version that has only been released for a couple of weeks then immediately deprecated.

    • May cause disruption to users that have already adopted the New-Delhi or J-Release versions

• Service Manager

  • Still working on adding boot-strap service exposures at SMO start-up - but its proving a bit more difficult than expected.

  • Manual registration via API is still working fine - but currently all Services need to be explicitly registered rather than auto-registered.

  • Hope to have a working solution soon.

• Working to improve API documentation generation from OpenAPI defns.

• Release K Planning:

  • No major update this week ... but will continue with more focus on demonstrators - esp aiming towards next F2F

• @subhash Hope to get started soon on integrated demo with AIMLFW & NONRTRIC

  • Can discuss more this week - and more discussion at RSAC next week.

SIM (@Alex Stancu)

• Still working on Heirachical OAM models, e.g. O-DU → O-RU)

  • Hope to demo at next F2F

  • https://lf-o-ran-sc.atlassian.net/wiki/display/SIM/Hierarchical+OAM+functions+Use+Case

• last week:

  • Working on Python O1 & OFH M-Plane simulators

    • Still on track & ongoing

OAM (@Martin Skorupski)

• Implementation for std-defined Alarms is now ready.

  • Ref: last week:

    • O-DU team would like to support std-defined alarms - but not showing up in SDN-R - so updates needed for SDN-R/ODLUX (to get events from kafka)

      • (newAlarms, clearedAlarms)

OSC Integration / INT (@fransiscus bimo )

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

    • e.g. Cloud Model placeholder at:

      • https://docs.o-ran-sc.org/projects/o-ran-sc-smo-teiv/en/latest/data-models-guide.html

      • https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=tree;f=teiv/src/main/resources/models

    • Want/ Need community engagement to use/experiment wilth models to help accelerate standardisation in WG10.

  • Working to add support for grouping/collection in registry & api

  • Working to add tagging/classifiers/decorators to help markup & expressive retrieval of data from TEIV

  • Need to start working with others in OSC & beyond to help populate TEIV regstry with data from their 'sources of truth'

  • Hope to make alot of use of TEIV in demos/rapps in K-Release

RSAC (@Rittwik Jana  @Martin Skorupski )

• Congrats to @Martin Skorupski - Now co-chair of RSAC - taking over from @David Kinsey [AT&T]

AI/ML platform project (@subhash )

• Minutes & Meeting: Meeting notes

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

• Still working on K-Release planning

• Similar to last week: Still understanding NONRTRIC SME & rApp manager

  • Last week: How to use/embed an Ml-Model in an rApp?

    • @John Keeney (Ericsson EST) Spec is very unclear how rApps use ML models or the AI-ML-Platform / model store.

    • Pre-spec implementation of NONRTRIC rApps can use KServe ML models - where KServe-wrapped ML Models can be LCM'ed as part of rApp LCM

      • Ref: Sample rApp: https://github.com/o-ran-sc/nonrtric-plt-rappmanager/tree/master/sample-rapp-generator/rapp-kserve 

      • Can be used/LCM'ed using rApp Manager: https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-rappmanager/en/latest/ & Release J: rApp Manager

• See above - NONRTRIC re planning for Demos etc at F2F
