    1. we mark items that you are >90% sure (=”committed”) to work on during 2H2023 with your label, like subteam-n (Nokia), subteam-s (Samsung) and so on. Items that are proposed for I release but not “committed” we mark with subteam-n-proposal, subteam-s-proposal and so on. To ease usage I created a couple of filters for follow up. See §7.3 from Jira usage conventions.
    2. input for release candidates: left overs and generally open items, RSAC

2023-06-06

Recording: partial-only: link to zoom recording

  1. Every time: Check rule RC-4 (link) that all L or XL commits of the last two weeks have also new unit tests. This is our policy. link-to-reviews (gerrit filter instructions // gerrit t-shirt-sizing).
    1. Last checked on 2023-04-11
      1. https://gerrit.o-ran-sc.org/r/c/ric-plt/xapp-frame/+/10923 OK, module version updates only
  2. every second time: Review code coverage stats and blocker code smells
    1. We take a look at the two links in the beginning of this page: Code coverage reports..
    2. The list below is only working reports // Anybody volunteering to work with LF on making the code coverage CI to work again (there's still the old JVM version)
    3. Thoralf did this last on 2023-05-23:  we did not do this this time

    12. RIC-894 long idle period (days) causes RMR connection breaks
    13. RIC-864 xapp-frame-cpp CI does not use Dockerfile and therefore uses Ubuntu18.04 (not 20.04) in build
    14. RIC-857 sporadically RMR takes multiple minutes before being "ready"
    15. RIC-852 Intermittent Issue with E2T: While setting up E2 setup request and response.

  7. 2022-12-13, 2023-01-17: Bin Yang asked about O2 for RIC platform deployment and xapp deployment. Need to discuss on this topic. O-cloud is deployed in AT&T and Taiwan lab.

    1. The current platform deployment scripts might not be in line with O2 envisions
    2. David Liu (WR) asked from James on O2 as well. James to check if a proposal on using X testing framework could also be used for integration. There's is also a link to robot test cases.
    3. O2-D(MS) is relevant to RIC platform.
    4. deploying xApps (LCM) is also an O2 issue - the alternative of using CRDs is not implemented in OSC RIC. Could be implemented as second option for deploying xApps.
    5. 2023-01-31: No news yet
    6. 2023-02-14: No news yet, Thoralf received e-mail on this from James. Still to check.
    7. 2023-02-28: some e-mail discussion. Ball's on Bin Yang & James side. Subhash and Thoralf discussed this and Thoralf to call a meeting with Bin Yang, subhash, James, Thoralf.
    8. 2023-03-14: AP-James Meeting was held. We see use cases around deploying RIC platform using helm charts over O2; and deploying xApps over O2. For xApps the role of descriptor->helmcharts→k8s manifests in SMO is still missing. AP for James to check with SMO project on ASD (porting or making available "ricdms/dmscli" to SMO; kserve adapter also affected as it uses ricdms) and support for deploying using helm charts and James to discuss with RSAC. Bin-Yang wants to check how RIC can be deployed using helm charts only.
    9. 2023-03-28: no news
    10. 2023-04-11: Tacker team provided ideas on SMO architecture (in context of RSAC). No immediate action items for Near-RT RIC platform project

      3. WR also want to contribute to xtesting for O2. CNF package definition still open and concept of DMS.
        1. discussion with Bin Yang in this meeting is possible. Maybe some proposal would be good.
        2. Tacker-based deployment needs to be checked.
    2. 2023-03-14, 2023-03-28 : no news

    5. 2023-05-09:
      1. Q-to-James: summary of what you presented in TOC (1 min) and let's raise question to all for input to integration project.
        1. Xtesting is used in integration project now (already for 6 months or so). Xtesting works also with robot test cases.
        2. James working in this integration for the test cases that are already in it/test. Infrastructure team also contributed O2 releated robot test cases (requires o-loud).
        3. Input from other subprojects, incl. our near-RT RIC project?
      2. James needs some hints on how to run the existing robot test cases in it/test related to missing env variables: GLOBAL_INJECTED_E2MGR_USER and APPMGR_ENDPOINT.

  4. 2022-12-13, 2023-01-17: Bin Yang asked about O2 for RIC platform deployment and xapp deployment. Need to discuss on this topic. O-cloud is deployed in AT&T and Taiwan lab.

    1. The current platform deployment scripts might not be in line with O2 envisions
    2. David Liu (WR) asked from James on O2 as well. James to check if a proposal on using X testing framework could also be used for integration. There's is also a link to robot test cases.
    3. O2-D(MS) is relevant to RIC platform.
    4. deploying xApps (LCM) is also an O2 issue - the alternative of using CRDs is not implemented in OSC RIC. Could be implemented as second option for deploying xApps.
    5. 2023-01-31: No news yet
    6. 2023-02-14: No news yet, Thoralf received e-mail on this from James. Still to check.

    8. 2023-03-14: AP-James Meeting was held. We see use cases around deploying RIC platform using helm charts over O2; and deploying xApps over O2. For xApps the role of descriptor->helmcharts→k8s manifests in SMO is still missing. AP for James to check with SMO project on ASD (porting or making available "ricdms/dmscli" to SMO; kserve adapter also affected as it uses ricdms) and support for deploying using helm charts and James to discuss with RSAC. Bin-Yang wants to check how RIC can be deployed using helm charts only.

    1. code changes, but difficult to test as difficult to change order of IEs in message.
  12. H release content
    1. we mark items that you are >90% sure (=”committed”) to work on during 1H2023 with your label, like subteam-n (Nokia), subteam-s (Samsung) and so on. Items that are proposed for H release but not “committed” we mark with subteam-n-proposal, subteam-s-proposal and so on. To ease usage I created a couple of filters for follow up. See §7.3 from Jira usage conventions.
