2023-08-29 (back to normal week, therefore only 1 week after previous meeting)

Recording: TODO

  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
  3. Every time: Check if there are new bug reports in JIRA: link
    1. RIC-1002 Abnormal signaling process cause E2Term crash (this could be a security issue)
    2. RIC-1001 RMR service should verify route tables.
    3. RIC-991 rmr related (not a duplicate) - Alexandre will take a look
    4. RIC-989 rmr (minor) security issue - Alexandre will take a look
    5. RIC-979 Decode Error with e2sim on e2term Pod - 2023-08-22: Abhijit still looking into this, but with latest Ubuntu packages this seems not to cause the problem anymore.
    6. RIC-972 URL for A1 mediator to align with spec.
    7. RIC-965 RMR wormhole connections uses stale endpoints to make connections 
    8. RIC-921 fix UT test case in e2mgr to stub time (leftover from review https://gerrit.o-ran-sc.org/r/c/ric-plt/e2mgr/+/8493)
    9. RIC-915 dms_cli for installing xapp not working (raised by James)
    10. RIC-905 new (from PW) Issue in reporting the CLEAR ALARM as VES EVENT
    11. RIC-901 new (from PW) BUG FIX IN 'Get ALARM INFO’ NETCONF COMMAND
    12. RIC-897 SCTP connection fails with Viavi // update with workaround → Thoralf changed this into an Epic (problem was on simulator side. But some useful extension on E2T comes from this as well)
    13. RIC-896 xapps sending same msg type and sub id fails - details to be clarified
    14. RIC-894 long idle period (days) causes RMR connection breaks
    15. RIC-864 xapp-frame-cpp CI does not use Dockerfile and therefore uses Ubuntu18.04 (not 20.04) in build
    16. RIC-857 sporadically RMR takes multiple minutes before being "ready"
    17. RIC-852 Intermittent Issue with E2T: While setting up E2 setup request and response.
      1. 2021-12-21: Trying to get bandwidth for this during F release.
    18. RIC-837 RMR is not forwarding messages from E2T to E2M
    19. RIC-835 → 2021-12-07 no news from Viktor
    20. fixed: ...

    1. 2023-08-01:
      1. O2 integration with OSC RIC is still pending with WR.

    2. 2023-08-22:
      1. Can we do pair-wise testing, e.g., between (1) xapp and RIC, (2) non-RT RIC ↔ near-RT RIC testing (only A1) ?
        1. E.g., KPIMON or bouncer xApp could be used. Sunil might be able to help.
        2. e.g., existing discussion with John
  5. Prashant's work in near-RT RIC(subteam-p)
    1. 2023-08-22 : could not participate

    1. 2023-05-23
        1. hw-rust xapp using xapp descriptor (config.json) works, but still fixing lifeness and readiness probe
        2. testing of subscriptions using hw-rust (facing the E2T problem)
    2. 2023-07-18: no news
    3. 2023-08-01: got logs from Subhash. Now ran into issues with Dockerfile in E2T (gcc related differences between ubuntu 20 and 22)

  9. Cap Gemini updates (subteam-cg)? 
    1. 2023-08-01

      1. Gunja to present conflict management design

      2. thinking about adding support for DU in E2T/E2M/RNIB in I release

    2. 2023-08-22:
      1. Gunja provided reviews for DU support. Nokia to reviewed and merged

        1.  https://gerrit.o-ran-sc.org/r/q/topic:%22Multiple+E2+Node+support%22 and  https://gerrit.o-ran-sc.org/r/q/topic:Multi_E2_Node

      2. conflit management status? Thoralf checks by e-mail.
  10. Himanshu (subteam-gs) would like to work on RIC-963
    1. code changes, but difficult to test as difficult to change order of IEs in message.
    2. 2023-06-06: Added unit tests (integrated in image building) - did some changes in the stubs (based on environment variables). Next step looking into this.
    3. 2023-07-18: Code changes almost ready for RIC subscription response - gerrit review coming.
    4. 2023-08-22: feedback from Anssi on submgr received and incorporating these changes, but not yet in review.
  11. Dhiraj (subteam-r)
    1. 2023-07-18: IPv6 changes to come as review
    2. 2023-08-01: working on it.
    3. 2023-08-22:
      1. checking compliance/license issues
      2. How are policy types created? xApps register by policy type and understands the schema that is bound to it. Non-RT RIC should create policies using the same schema (there's a GUI for this on non-RT RIC side).
  12. Alexandre (subteam-utfpr)
    1. 2023-08-22: Alexandre couldn't participate, but informed after the meeting by e-mail: "My plan for the next two weeks is to fix both RIC-989 and RIC-991 issues."
  13. Nokia (subteam-n)
    1. 2023-08-22: want to work on RIC-997
  14. I release content
    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
    3. Sprint dates
      1. Sprint I release dev sprint 1: Aug-21 to Sep-10
      2. Sprint I release dev sprint 2: Sep-11 to Oct-1
