Winlab servers (OSC Test lab) (@Martin Skorupski, @Ivan Seskar)

• No Update this week

• @Subhash & Bimo working together on a server to test AIML

OAM (@Martin Skorupski)

• No major update this week:

NONRTRIC (@John Keeney (Ericsson EST))

• Working on stabilising SMO-install scripts & charts & sample rApp

• Experimenting with Nephio & smo-install

SIM (@Alex Stancu)

• No update

AI/ML platform project (@subhash)

• No update

• Minutes & Meeting: Meeting notes

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

• Working on Model deployment as/in an rApp 

  • Hope to share a design document in coming weeks

• Working on Inference services

  • Still at design stage but making good progress. 

• Would be good to work together (Bimo, Subhash, Bimo) to build/show the integrated SMO/AIMLFW deployment 

• Maintenance release complete.

  • @subhash & @Sridhar Rao confirm. 

  • Wondering if a branch is need for maintenance release?

SMO (@Seshu Kumar Mudiganti)

• Meeting notes Meeting notes

• No update

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

  • Looking at how to build an adapter for O2 information to try populate CLOUD domain entities & relations - v. early stage. 

RANPM files for O-RUs (@Sridhar Rao)

• O-RU File-based Performance Management

• Will continue to look at this 

• Question: is the schema for the file (CSV) defined yet? Anyone have a sample?

  • Based on - but not directly interpretable - from O-RAN Management Plane Specification v18.00 18.0 – LINK – Section 10.3.2 – File Upload

• Parser will be very difficult. - Is there any point in pushing files to SMO that cannot be parsed? 

• In hierarchical mode - the O-DU needs to parse data from O-RU to re-present it as O1

  • The format of the data from the O-RU may be similar to the OFMP-PM data sent to SMO in Hybrid mode ??? 

  • If so, how do O-DUs parse this? Anything available we can reuse? 

  • Sridhar will have a look in his wider community .... 

AOB:

• RANPM Install Questions (@Subhash)

  • Older RANPM install doesn't seem to work with K8S version 1.32.3 (as recommended by Bimo in general platform install script) 

  • Strimzi version incompatibilty when installing older ranpm install scripts. 

  • Using it/dep smo-install version: Saul & Sridhar tested with K8S 1.32.3 - Aravindhan 1.32.7 

    • Suggest using smo-intsall scripts/charts with ranpm override/flavor

      • ./2-install-oran.sh ranpm

  • Need to deprecate older installs / guides etc. No longer supported. 
    
    

• Is there any test data in TEIV?  @Sridhar Rao

  • Yes. See unit tests & function tests. Some sample data can be found in the repo for those:

    • There is an option to pre-populate teiv with sample data using https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=blob;f=docker-compose/docker-compose.yml;h=ae9b20af4c5355c1a4682b9c6fae97d3bc6f8e25;hb=HEAD#l45

      • https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=tree;f=docker-compose/cloudEventProducer;hb=HEAD

  • Otherwise we need adapters to populate the data.

    • We only have a couple now

      • https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=tree;f=adapters;h=8216983a8e72f81e6a47fb7a67035cbc16dd7382;hb=HEAD

      • https://gerrit.o-ran-sc.org/r/gitweb?p=oam.git;a=tree;f=code/network-generator - using the 'teiv' output format to create a dump of cloudevents 

      • More adapters on the way this release. 

    • You can easily write new adapters / stubs by publishing to event interface: 

      • Create a cloudevent & publish it to kafka  - e.g. using https://cloudevents.github.io/sdk-java/kafka.html

      • https://docs.o-ran-sc.org/projects/o-ran-sc-smo-teiv/en/latest/discover-and-reconciliation-interface.html

      • https://gerrit.o-ran-sc.org/r/gitweb?p=smo/teiv.git;a=blob_plain;f=teiv/src/main/resources/v1/topology-exposure-inventory-kafka-asyncapi.yaml;hb=HEAD
        
        

• Any Sample RANPM consumer rApp?: (@Sunil N)

  • See Demo at Montreal: 

    • 2024-10 O-RAN F2F Montreal#2024-10O-RANF2FMontreal-8 

  • See sample DME consumer rApps (not RANPM)

    • https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric/plt/rappmanager.git;a=tree;f=sample-rapp-generator/rapp-sample-ics-consumer;h=1d6f7ef7d422ed7ba40c8b63c903634a99a5a9e2;hb=refs/heads/master

    • https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric/plt/rappmanager.git;a=tree;f=sample-rapp-generator/rapp-simple-ics-consumer;h=98fc0e90ce1feccd98d8dc9b2798d0b86c2cdeba;hb=refs/heads/master

    • These rApps should be extended to use the ICS/DME data-type produced by the PMProducer function in the RANPM toolchain

      • https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-ranpm/en/latest/pmproducer/index.html

      • Note: The specifics for the DME type produced by the PMProducer depends on how it is configured.
        Once PMProducer is running & available to produce data, suggest querying ICS to get more info on the Data type to help identify what the consumer needs to consume that data (create a job). 

  • See sample RANPM rApp at: 

    • https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric/plt/ranpm.git;a=tree;f=pm-rapp;h=70f4fcdd4ebd3ae94407136a43d328fb6078af81;hb=HEAD

    • But this is just the docker image for the rApp uService. It would need to be adapted wrapped in an rApp and created using rApp Manager. 
      
      

• Who will use the services expose by rApps? (@Sunil N)

  • Other rApps.

    • e.g. if you have a collection of rApps working together. 

  • Can also be used to expose platform services from rApps.

    • But may not be a good idea - Platform services are probably not-transient like rApps.

    • Probably not a good idea to have platform services appear/disappear. 

    • SME currently does not different between platform services (SMOSs) & services provided by rApps. 

      • Once the Decoupled SMO concept matures, SME could be used for SMOS↔SMOS service exposure/discovery
        
        

• PRB utilization use case (rApp & ML) (@Sunil N)

  • Working with sample/sim data to train a model, then deploy as a rApp

  • Good use case to progress AIMLFW integration with rApp toolchain (@Sunil N, @subhash, @John Keeney (Ericsson EST)

    • Training, Model deployment & inference service LCM. 

      • e.g. would like to see different options for model & inference service containment & LCM - both 'inside/part-of' to rApp, or outside rApp using AIMLFW functions.
