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. https://gerrit.o-ran-sc.org/r/c/ric-plt/xapp-frame/+/7955 ok, removal of deprecated code
  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. We did not do this today.
  3. Every time: Check if there are new bug reports in JIRA: link
    1. RIC-897 SCTP connection fails with Viavi
    2. RIC-894 long idle period (days) causes RMR connection breaks
    3. RIC-896 xapps sending same msg type and sub id fails - details to be clarified
    4. RIC-890, RIC-891, RIC-892: build of xapp-ccp framework seems to fail.
      1. could be staging repo related (10004) vs release repo (10002) for the base image
    5. RIC-864 xapp-frame-cpp CI does not use Dockerfile and therefore uses Ubuntu18.04 (not 20.04) in build
    6. RIC-857 sporadically RMR takes multiple minutes before being "ready"
    7. RIC-835 → 2021-12-07 news from Viktor
    8. RIC-837 RMR is not forwarding messages from E2T to E2M
    9. 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.
    10. fixed: RIC-895 (routes in routing mgr for service update messages)
    11. anybody would like to get more familiar with RMR?
  4. Sunil still to discuss with other team members for other items from subteam-h
    1. Other tickets CI/CD and Code coverage tickets? Sunil: I am still looking for the resources to work on that.
    2. 2022-03-01_
      1. Sangeetha working on RIC-860, done, but code still to be checked in.
      2. Sangeetha working on RIC-878, status see Jira item, code still to be checked in.
      3. O1 testing is also being worked on. 2022-03-29 Sangeetha to raise Jira ticket
      4. Subhash asked for documentation of nanobot from Sunil. almost done.
    3. 2022-03-15: status Sangeetha?
  5. James: RSAC recommended incorporating OTF in testing (David Kinsey can help)- Thoralf to start mail thread with HCL (sunil, Sangeetha) and David on this plus James.
    1. 2022-01-27 (Mail sent)
    2. 2022-02-15: resending with the right David
    3. 2022-03-01:
      1. workshop to be planned (James in discussion with David)
      2. in last weeks SMO+RSAC meeting this was discussed as well. It would be good to have a test case that just verifies successful deployment of the RIC platform, workshop still to be scheduled.
      3. James ran O-ran profile in powder lab. Seemed to work and deploy Dawn. Working with David Jo. (UoU) to update to E release.
      4. 2022-03-15: James creating a E release profile for powder
    4. 2022-03-15: workshop still to be held (was moved by two weeks (Mar-24))
    5. 2022-03-29: workshop planned for April-7 9am EDT https://lists.o-ran-sc.org/g/discuss/message/487
  6. Progress on E2APv2.0?
    1. in ric platform and simulators?
      1. Any first code/design review request that Arun and Dhiraj should review?
      2. progress, subhash: simulator adapted. E2T changes internally ready.
      3. Subhash&co did not plan to do any testing on xApp side.
      4. thoralf to sent invitation to Subhash &co for Friday → DONE
        1. agreed on configuration transfer to be handled similar to function definitions as E2APv2.0 now defines configuration updates as replacing instead of updating existing component configuration entries.
        2. E2 reset to be handled as new state that xApps see: "connected---transition1-->connected-but-under-reset---transition2-->connected". We use a timer, instead of strict xapp and submgr confirmation that all has been cleaned up. xApps shall resubscribe only after transition2. xapps can assume that submgr has removed all subscriptions (in its view of the world) and that the E2 node has removed them (in its view of the world)
        3. Subhash will send slideset for this during this week
        4. E2 implementation status and reviews coming?
      5. 2022-03-15 any news?
        1. do we need an E2APv2.0 branch (submgr used/uses e2ap-v02.00)
          1. if we create a E2 branch now we can do the review in that branch. E2T, E2M, and RNIB. submgr already has branch.
          2. Subhash to ask from Alex Stancu for branch in E2 sim
        2. Already initial versions of the work? Dhiraj and Arun are available for reviewing.
        3. updated design: E2AP 2.0 Design
        4. Could provide initial version in which config handling (IE in E2 Setup) is just ignored.
        5. AP: Subhash to present he E2AP2.0 slides (15min)
        6. A1 mediator work proceeding (two more APIs)
      6. 2022-03-29
        1. AP: Subhash to present he E2AP2.0 slides (15min) from here: E2AP 2.0 Design

        3. protobuf definitions for configuration components under re-work
        4. E2APv2-0 branches? nodeb-rnib already branched.
    2. in xapps? E2APv2.0 update in xApps that use the old RMR to-be-removed xapp subscription interface - Thoralf asking Sunil to coordinate xapp-side adaptation to REST interface - see RIC-375
      1. kpimon
      2. bouncer (working on rest based submgr API if that means HCL is working RIC-641, please inform Alexandre about this.

        3. 2022-03-15: Still open corner case where registration is not done yet, but sub requests are already sent. Thoralf to ask from Nune.
      4. update simulators (discuss with Subhash if needed) do we have two simulators we have to update?
        1. done, but not yet open for review.
    3. in DU
      1. 2022-02-23 user-30c9d reported in TOC that this work is done.
