Reminder from previous weeks:
- OSC SMO calls now move to its own time slot - Thursdays
- See OSC RSAC Calendar: https://lf-o-ran-sc.atlassian.net/wiki/display/RSAC/calendars
- (Note this meeting to open to anyone, including non-ORAN members)
- We will maintain this slot for ONAP Alignment, and try flag issues/question to/from SMO meetings.
- See OSC SMO Project meeting notes

OSC Project roundup:

NONRTRIC (John Keeney (Ericsson EST))

Prototyping building blocks that might be useful in the future for rApps and R1
- Many rApps will likely contain helm charts so working on a function to do basic lifecycle management of helm charts
- A major part of R1 platform will center on service & API exposure. Experimenting with Kong.
Working hard to increase test coverage & tidy up NONRTRIC control panel.
Working on updating Gateway function for the Control to use.
In ONAP: A1 Policy Management needs to maintain state.
- Implemented as persistent state storage to local storage, which can then be realaised as a K8s persistent volume for state to store/share state across k8s pods and pod restarts
- May need to use something more complicated later, e.g. DB-backed.
- Working with OSC IT/DEP and ONAP OOM teams to add these changes to deployment scripts

SIM (Alex Stancu)

Prepared 2 docker images
- O-RU simulator with Nov train yang models
- O-DU simulator with hello-world usecase yang model

OAM (Martin Skorupski)

VES std-defined event functionality (See last week) to allow other SDOs to inject their schemas into VES body
- Unlikely to be demonstrated in D Release
Updated Heloo-World usecase YANG model for O-DU. Still under discussion at RSAC/TOC level - pending reviews. Ref:
- RSAC meeting (2021-04-08),
- JIRA ODUHIGH_322.,
- gerrit review 5870.
- wiki page
O-DU team confirms ability to send PNF registration VES message and see Netconf session established.
Request to come up a generic OAM adapter (temporary solution/workaround) to translate to O-RAN conforming interface - External to the network function.
- Still under evaluation/discussion. More to follow later.

ONAP-OSC & QA:

Discussion about LFN 5G Super Blueprint
- https://wiki.lfnetworking.org/display/LN/LFN+Demo%3A+5G+Super+Blueprint
- https://wiki.lfnetworking.org/display/LN/5G+Super+Blueprint+Timeline
- OSC may be involved in Phase 3.
- Alot of confusion/discussion about how this could be realized
- Ref also RSAC meeting 13/Mar - Recording
- Some questions:
  - Who will do all the integration? Drive requirement?
- Kenny Paul provided some additional background
  - Landing Page: https://www.lfnetworking.org/5g-super-blueprint/
  - Wiki Page: https://wiki.lfnetworking.org/x/EAADAw
  - Mailing List/Calendar: https://lists.lfnetworking.org/g/lfn-demo
  - Encourage anyone to join the bi-weekly meetings, (next Tuesday 20th @3pm UTC)
- John Keeney (Ericsson EST) Who's driving this? Has it resources of its own?
  - Kenny Paul LFN drives, & depending on resourcing from participating projects
- John Keeney (Ericsson EST) Where there are multiple solutions who drives adoption/architecture decisions?Is there a big picture/goal?
  - Kenny Paul Multiple options exist & need further discussion. Idea to try prove just a small number (or 1) proof point from the many different options.
- John Keeney (Ericsson EST) Please confirm relation with US Gov & US military
  - Kenny Paul Ref https://usgovops.org/ops5g/ & https://www.darpa.mil/program/open-programmable-secure-5g
    - Open to everyone & everything is opensource. US Gov would be a consumer/user.
Topology Modelling work ongoing in ONAP Martin Skorupski Andy Mayer
- Looking at use cases
- John Keeney (Ericsson EST) Is there alignment between O-RAN Alliance & ONAP (& OSC) on this?
  - Andy Mayer That's the idea, but no concrete plan yet. Still working on it
  - Martin Skorupski Need multi-domain topology model - especially for FM for example - so perhaps ONAP is the best home since it's more over arching?
  - Must be able to deal with & provide mapping between models & domains. Lots of work!
  - Aim for Meta-model first & then support domain models & mappings etc.

Alarm Dictionary work ongoing in ONAP Martin Skorupski
O-DU O-RU FH Connection supervision hello-world use case ...
- Will use normal VES collector 1.9.0 from ONAP
- Plan to use DMaaP to pass events to NonRTRIC DMaaP 1.1.8
  - Will see a an alarm DMaaP message with FH connection is brought down
- Netconf client will be SDNR/CCSDK.SDNC 2.3.1
  - Will expose RESTCONF NBI to configure O-DU to bring FH conenction back up (Adminstrative State → Unlocked) .
- Still examining different options to implement NONRTRIC link monitor function / app. Still not completely clear yet.
- Need to work a little on helm charts for OAM/NONRTRIC/SMO environment for the use case.
  - Multiple charts is probably fine - so long as all in same cluster
- Will use AdministrativeState to bring FH connection Up/Down ... probably not the exact purpose for the AdministrativeState value ... but OK for this hello-world use case.
  - e.g. O-DU needs to "shut down" the FH conenction when "LOCKED" ... but this might not be "normal" real-world behavior
  - O-DU should kill the conenction
  - O-RU should send alarm
Former user (Deleted) Will speak next week about CPS
