I refactored current Jira’s base on our discussion:

• https://jira.onap.org/browse/DCAEGEN2-2873 (bug)
• https://jira.onap.org/browse/DCAEGEN2-2874 (VES 7.1 enhancements)

And also create a new one:

• https://jira.onap.org/browse/DCAEGEN2-2880  (support for VES 7.2)

The following 3GPP CM notifications specified in 3GPP TS 28.532 [4] are supported in O-RAN:

 notifyMOIAttributeValueChanges

 notifyMOICreation

 notifyMOIDeletion

 notifyMOIChanges

Its syntax is defined in

Shankar: point to a 3gpp....zip (https://www.3gpp.org/ftp/Specs/archive/28_series/28.532/28532-g81.zip → v16.8.1)

Marcin has looked into it. 

• to complete and validate the entire json - additional yamls are required.
• there are reference inside to other schemas - needs to be analyses - for validation on the ves-collector.
  • more infos next week

OOF-SON use case roadmap from last June.

Marcin was referring to slide 16 in this June 2021 LFN slide deck for the ONAP-SON use case. https://wiki.lfnetworking.org/download/attachments/56066778/LFN_June2021_ONAP_SON_Rel9_20210610_v1.pptx?version=1&modificationDate=1623339917000&api=v2

• VES message handling on SDN-R 
  • used to update CPS
  • code is in ccsdk/features - northbound (CM Notification Support in ONAP)
  • DCAE VES Collector - implementation for VES 7.2 in Honolulu  
  • TODO: add link to nexus dcae-ves-collector–image.... (???1.8.0???)

    • (Updated afterward: Minutes & Recording: https://lf-onap.atlassian.net/wiki/display/Meetings/2021-06-25+Meeting+notes)
  • Attempting to replicate functionality in OSC OAM/NONRTRIC/SIM demo - based on OSC charts.
    • Mainly updating charts etc.
    • Certs need updating
  • Will be testing in ONAP WindRiver lab - setup etc.   Might be a good place to collaborate.
•  John Keeney Any update on how to reuse OSC & other external components?
  • @Christophe, will be challenging in OOM, & need to reuse structure & some charts from OOM
• John Keeney Any ideas where SMO would be different from "Full ONAP"
  • @Christophe: Plan to start with OSC charts/flavour ... then depends on Usecases ...
  • Hope to be able to make use of the override files to create different flavours .. aiming for something similar to OSC version
    • Ref Closed loop use case & "D" Release - Closed Loop Use Case: Simulation of O-RU and O-DU & "D" - Closed Loop Use Case 
• John Keeney Probably need different versions for different usecases
  • @Christophe ... OOM have this same idea to have multiple flavours.  Discussion gets broader when non-ONAP components are added.
• @NK Shankar ... Should also consider SON and Slicing usecases.
• John Keeney Recall that the OSC D release usecase is not real world ... and will mature in coming releases. Currently mostly treated as an integration requirements driver
  • Ref Closed loop use case & "D" Release - Closed Loop Use Case: Simulation of O-RU and O-DU & "D" - Closed Loop Use Case 
• @Christophe @NK Shankar Need to consider diversity of DCAE components used.  Also need to figure out how different simulators could co-exist.
• Lets continue discussions on Friday Call?

INFO from Christophe - 2021-06-30:

Just a few notes:

• We have agreed with ONAP and other members of O-RAN SC to keep an ad-hoc call on Friday to discuss technical details for now (will remove this meeting once all details are sorted out and use the joint meeting to report status)
• Main comment from John is that we cannot consider an SMO deployment without having a way to deploy Non-RT-RIC as well as ONAP components (hence a debate on how this should materialize : extend OOM? )
• We have progressed on the POC in the meanwhile, Sebastien had an idea and has pushed a small repository on github to show what we are doing for now to create a unique installation for O-RAN, trying to implement the following idea:
  
  • Started from IT/DEP repo, containing some Helm charts for O-RAN (including Non-RT-RIC)
  • Seems an embryo of using ONAP charts to deploy SMO components but sounded like a fork of ONAP charts
  • Instead of copy pasting OOM charts, he create a git submodule referring to oom ONAP charts repo (to keep ONAP untouched)
  • Rework the O-RAN charts to map them to the OOM structure (like OOM'ized O-RAN charts)
  • Try and build (created some makefiles, inspired from ONAP) then push them to a single chart repository
  • Merged ONAP override and O-RAN override to have a single file
  • Created an Install script to deploy the charts in a single Namespace
  • … it worked more or less

We plan to show that maybe on Friday call (https://lf-onap.atlassian.net/wiki/pages/viewpage.action?pageId=15480760)

  • https://lf-onap.atlassian.net/wiki/display/DW/O-RAN:+ASD+solution

2021-07-07:

way forward

• release helm repo by OOM should be created
  • (Added later: John Keeney (Ericsson EST) Also asked about getting a helm chart repo for OSC.  https://lists.o-ran-sc.org/g/discuss/message/331)
• demo was shown last Friday how it could look like
• next step
  • sample overwrite files
• if access to the "demo git" is required, please reach out to ChrisC Sebastien Determe Gervais-Martial Ngueko

2021-07-14:

• https://github.com/gmngueko/oran-deployment/pull/1
• in non-overwrite helm only docker from "released" nexus should be included...

2021-07-21:

• from John Keeney (Ericsson EST) LFN ticket required to put helm into nexus
• control about helm from different project

2021-07-28:

• not much additional features required for SMO deployment.
• next step in the area of CNF deployment in combination with SMO
  • as demoed one year ago by Samsung (including closed loop and A1 Policies)
  • use case will be updated to Honolulu 

2021-08-04:

• no updates on last weeks call
• cnf deployment - reuse of existing use case implementation.

2021-08-18:

• demo of by Samsung for CNF deployment - recording available on the Friday meeting wiki
• updates on OOM for O-RU-Sim and O-DU-Sim deployment as CNF
• work in progress

SON use case

• based on O1
• How to include A1 in the SON use case? for the Network Slicing Use Case
• Will be discussed on Use case Realization call (on Mondays)
• use case in O-RAN-SC regarding Network Slicing - similar but not in all details
