Re JDK17 Docker image sizes: @Kamel Idir Any plans to use GraalVM-based images? @John Keeney (Ericsson EST) Looking closely at it, but don't feel we're ready yet.

SIM (@Alex Stancu)

Working on O-DU simulator with 3GPP Yang Models. Currently script-based to build custom images - avoids 3GPP licensing issues.
PM File generation
- @John Keeney (Ericsson EST) @Alex StancuNo update

OAM (@Martin Skorupski)

Scripts for injecting 3GPP models for Yang (CM) & Yaml (VES) from external repos.
- Including VES collector configuration - currently manual → scripted
  - Schema validation already working.
- Currently dockerfile / compose, moving to K8s.

O-DU (@Hariom Gupta @Vidhu (Deactivated))

ONAP / OSC / O-RAN Alliance: Cooperation & Alignment

@N.K. Shankaranarayanan Presentation of slides discussed in past weeks at RSAC call today. See above.
- Slides:
  - https://lf-o-ran-sc.atlassian.net/wiki/download/attachments/12518526/ONAP_OSC_Areas_20230321.pdf?api=v2
  - Based on discussion of topics on : https://wiki.onap.org/pages/viewpage.action?pageId=162105284
  - Recording: (second half of) https://zoom.us/rec/share/D3ZkRsAQ1lu9QY1zomJmAnmXzAUL3FTWJSFqCPDIUKVmZ96HbEu7DQLy34yidjDe.GMyDeZXm34UwgOSR
- Excellent session to make people aware / motivated about overlaps, with concrete opportunity for better alignment & engagement.
@Seshu Kumar Mudiganti We also need to think about Non functional aspects, such as scalability, security, energy usage. @John Keeney (Ericsson EST) Those are costly. Trade off against resources available for functional aspects. Do we need to find out if there is a preference for functional vs non-functional?
Lots of hard work to do. We will try to identify concrete follow ups.
Lets continue on the areas we already have good alignment, & strengthen focus on newer potential areas, as described int he slides.
