  2. RIC-360 any progress. Discussion with Nune and Nithin kept?
    1. deployment script changes (Abdulwahid) related to helm3. Discussed with Felix (onboarder (felix)  changes still needed).
    2. appmgr changes no discussion → Nune
    3. Thoralf to invite meeting with Alok + Sri + ramesh (still this weeks)
    4. Status: working on go code changes in appmgr

  11. RICAPP agenda: RICAPP Meetings.

2020-09-15

Recording: near_rt_ricplatform_and_ricapp_meeting_2020_09_15.mp4

  1. Schedule for R6 (second half of Cherry: Jira usage conventions → §6).
  2. demos for demo day (next week Thursday = Sep-24 in 2020-09-24 Cherry R6.1 - CANCELLED)
  3. Subhash: move on with exact contribution.
    1. [1] Higher abstraction level in xAPP framework SDK (golang) [https://jira.o-ran-sc.org/browse/RIC-366]
      1. We discussed possible abstraction of this on API level. Matti said one person on AT&T side has been working on this before. We need to set up a separate meeting on this: Subhash, Nune, Matti, Neeraj Gupta (HCL), Vaishali (HCL), h_w.park@samsung.com, Akash (bouncer xapp) Identify new capabilities that we can implement on xapp framework side. Focus on things not yet implemented in any xapp frameworks. presentation by  h_w.park@samsung.com on what is planned. Aim for 10am EDT (NewYork) on Monday, Sep-21
      2. RIC-80 is already in progress by Antti teams.
      3. general goal xApps should only rely on E2SM, but do not need to touch E2AP messages (using ASN.1). So, a good abstraction would allow xApp implementation without ever touching an ASN.1 compiler if an E2SM would be defined in something else than ASN.1. We can discuss this further in the Monday meeting.
    2. [2] Support for E2AP RESET procedure  [https://jira.o-ran-sc.org/browse/RIC-383]
    3. [3] Developing version of xAPP [https://jira.o-ran-sc.org/browse/RIC-120]
      1. existing "hello world" is C++, but does more than just saying "Hello world", e.g. has own service model. Additional demo xapps in go/python are welcome. For go see in xapp-framework for Go for some skeleton code.
      2. for example, it would be good to have E2SM support for "hello world" E2SM in the simulator.
  4. Alok RIC-509 works better with Ceph (instead of NFS). Meeting to discuss how to integrate this to be called by Alok.
  5. Akash asked about the hello world xApp in terms of a new bouncer xApp (for benchmarking). Pls. contact Matti to get you in contact with hello world expert. Akash to attend also the Monday meeting.
  6. (post-meeting addition): Ron now merged the patch into the E2 simulator: https://gerrit.o-ran-sc.org/r/c/sim/e2-interface/+/4700 Work on the simulator can now continue.
  7. (post-meeting addition): RIC-360: continued work on appmgr // RIC-509: testing JJB templates in sandbox (sandbox permissions obtained) // RIC-150 Able to send RIC Subsription Request message from Bouncer xAPP to E2 terminator. Working on handling of the RIC Subsription request message at E2 terminator to E2SIM. Debuging is in progress. Able to exchange E2 Setup request and response. RIC-149: Ricdeployment Testsuite - existing issue got fixed except statefulset, working on this. Sent code modification to Dave and Bharath for review. Healthcheck Testsuite - Interface.robot files missing for few components got fixed and added keyword healthcheck for missing components as well. Working on dbaas, submgr related inerface.robot parameters to add and test. E2E Testsuite: Working robotxapp deployment using http post request using both manual and robot automation.
  8. RICAPP agenda: RICAPP Meetings.

Recording: near_rt_ricplatform_and_ricapp_meeting_2020_09_01.mp4

  1. S1+S2 team any news?
    1. Rahul progressing on RIC-95. Thoralf will help with testing as E2 simulator is needed.
    2. Subhash interested in picking up items on near-RT RIC platform. Thoralf to send information package.
    3. Double-check progress on E2 simulator in simulator project. Action item-Matti: check with Ron. Make sure to to add copyright and license statement.
    4. RIC-372 (sdlpy now supports notifications) now done.
  2. H1 team any news?
    1. RIC-109 (helm/k8s upgrade) Working on Non NFS based cluster storage on k8s
    2. RIC-509: HCL to present output/status of RIC-509.
      1. analysed com-pylog project on sonarcloud using our a/c
      2. Matti noted that xApp's MC xapp has done the same. Always needs to involve LF support case. HCL to include Matti in discussion.
    3. RIC-360: Go lang based code changes in progress
    4. RIC-150: (e2e benchmarking) Working on the Bouncer xAPP Implementation. "successfully built the e2apv1sim code manually in the LAB and run the e2sim binary. The e2sim sending the E2 setup request message to RIC terminator. The RIC terminator received the E2 setup message and it is not sending the response to e2sim. Because, in decode part of E2 setup request message in RIC, some parameters(RANfunction_Item) are not handled in RIC side and it's giving the decode error."
    5. RIC-149 (testing): Started fixing up the health check of ric component testsuites with few missing keywords and missing riccomponent_interface.robot files. As we confirmed with Bharath and Dave we are proceeding to fix the healthcheck and e2e testsuites related issues. Status: In progress Issue: Currently working on this while adding a1mediator interface.robot file " <tpl ($content).AsConfig $>: error calling tpl: Error during tpl function execution for "a1mediator.robot". Due to this some component related files are not mounted to nanobot pod.

    1. reply: " from near-RT RIC side we work with: (1) Akraino REC as the Akraino blueprint that we integrate RIC with (2) Nokia investigating if we can provide a wireshark dissector for E2AP (pending discussion with O-RAN alliance) (3) We're using the VESPA (Prometheus to VES adapter) project.
  5. Anything to demo on Thursday? Matti (50/50)?
  6. RICAPP agenda: RICAPP Meetings.

2020-08-18 special meeting on E2 simulator

Recording: 2018_08_18_special_meeting_on_e2_simulator.mp4 (no meeting notes created)


2020-08-18

Recording: 2 parts: near_rt_ricplatform_and_ricapp_meeting_2020_08_18_part1.mp4 and near_rt_ricplatform_and_ricapp_meeting_2020_08_18_part2.mp4

  1. Note that previous demo was on Thursday, 2020-08-13 Cherry R5.4. Recording available on the confluence page.
  2. RIC-628 now also fixed. Together with the earlier fix of RIC-444 this should now remove any issues with unintended dependencies on E2SMs. Now the RIC platform should again be independent of E2SMs. Note that the new routing manager implementation >0.6.1 requires an update of the routing manager helm chart as well. These helm charts are in master branch of repo ric-plt/ric-dep.
  3. RIC-509 we are aiming for CII (core infrastructure initiative of the Linux foundation) self-certified badge "basic". Need to check what basic "passing" badge actually implies. Initially this might be a reasonable aim: (1) Weekly static code scans by SonarCloud, (2) Weekly scans by NexusIQ for outdated 3rd-party packages/libraries (3) All critical and major vulnerabilities are remediated, (4) automatic code coverage is 80%-90%. Note that originally we planned for Cherry: "80% for all existing components and 50% code coverage for new ones."

    1. The below projects are onboarded to SonarCloud but not scanned. 

      ric-plt-e2 ric-plt-sdlgo ric-plt-xapp-frame ric-plt-appmgr ric-plt-dbaas ric-plt-dbaas-hiredis-vip ric-plt- nodeb-rnib ric-plt-submgr ric-plt-utils ric-plt-jaegeradapter ric-plt-tracelibcpp ric-plt-tracelibgo ric-plt- vespamgr ric-plt-asn1-documents ric-plt-streaming-protobufs ric-plt-ric-test ric-plt-ric-dep ric-plt-demo1

      not in sonar: com-golog com-pylog com-gs-lite

    2. None of the components except ric-plt-a1 (scanned 3 months ago) is onboarded to NexusIQ.

  1. Recording of Jul-2 demo: TODO (pending Matti)
  2. Thoralf on holiday Jul-21. The Jul-7 meeting we still have normally. Matti (hiltunen@a...) to host the Jul-21 meeting.
  3. After discussion with xApp PTL (Matti), we will use the old existing empty repo "utils" as a general repo for small utility-like code. The first usage will be for RMR-to-VES mediator (event converter) "platform xapp". This work is done under RIC-420.
  4. discuss contributions by HCL .

    1. Assign to Alok Bhatt:

      1. ricp-integration RIC-360: plan and prototype helm upgrade with xApp manager, REC, RIC infrastructure

                      Which K8S version with Helm 3 support to move to? Is 1.18 confirmed? Yes

                      App owners with whom we need to work with for this co-existence of Helm 2 and 3 change and for doing post deployment check / sanity testing? xapp manager, it-dep, ric-dep, Schedule meeting with Lusheng and Felix, Abdulwahid.

      1. ricp-e2e RIC-509: Components supporting continuous integration infrastructure, e.g., static code analysis. Schedule meeting with Lusheng

      Pl share more info on LF CI/CD. Sonarcloud or SonarQube? Jenkins Job Builder / Chained CI?Schedule meeting with Lusheng

      1. DBaaS RIC-109: DB: study: SDL scaling with Redis cluster (instead of sentinel) Schedule meeting with Jussi.

      App owners with whom we need to work with for doing this before and after comparison for this move from Sentinel to Redis Cluster mode? Should be transparent to user

      Output format expected from this study, if any

      Assign to Sangeetha KR:

      1. ricp-e2e RIC-149: Define and implement automated test cases for flows to be defined early in Bronze-R4

    2. Pl enable community lab access for us to work on these. → connect with Lusheng for how to use TLab.

    3. We manage this existing team mapping, but the items are assigned to Alok and Sangeetha.
  5. discuss contributions by Samsung

    1. For now, we would like to get your opinion regarding adding pub-sub feature to sdlpy/xapp-frame-py. As far as I know, this feature is already exists in sdlgo, but there seems to be no ticket related to this feature.

    2. This would be item RIC-372. Note that this is not related to xapp-frame-py, but to sdlpy only. Thoralf to reply to Timothy John Ebido. 
    3. item in JIRA to be assigned to him. Note that right now we have notifications only in go, but not in python or C++.
  6. ricapp meeting

2020-06-23

Recording: near_rt_ric_platform_project_meeting_2020_06_23.mp4

  2. Thoralf on holiday Jul-21. The Jul-7 meeting we still have normally.
  3. Bengi asked for RMR performance data comparing old NNG against SI95 implementation. Nothing on wiki page, but we have the PDF in
    Jira
    serverORAN Jira
    serverId5ec52304-b77c-3ce7-af6a-112cb13e6008
    keyRIC-48
    that might help. Matti to ask Scott to eventually post the results also in the wiki page. Also to double-check that SI95 results are not already in wiki page somewhere.
  4. Chokha interested in contributing to near-RT RIC.
  5. Rittwik asked about what we should push to the maintenance release. So far nothing. Matti asked about adding alarm routes to routing manager. We created
    Jira
    serverORAN Jira
    serverId5ec52304-b77c-3ce7-af6a-112cb13e6008

2020-06-09

Recording: near_rt_ric_platform_project_meeting_2020_06_09.mp4

  1. new contributors (Rahul) planning to work on RIC-203 implementation with Abdulwahid and on RIC-133 xApp scalability with Matti.
  2. presentation to O-RAN alliance: 2020-06-08: Report to O-RAN alliance on plans for release "Cherry" under Project reports
  3. demo moved by one week. We now demo in the first week of a sprint. For Sprint 1 in near-RT RIC we don't have a demo. First one for sprint 2 will be Jul-2.
  4. committer change: Tommy → Chris L. (in a1, rmr, xapp-frame-py). Remove rajesh from RMR. Katri and Roni to be removed from all repos. Need a replacement.
  5. RICAPP agenda: RICAPP Meetings.

2020-05-26

This event is cancelled due to overlapping workshop. Next meeting will be in two weeks in regular time slot.

2020-05-12

Recording: near_rt_ric_platform_project_meeting_2020_05_12.mp4

  1. Review and agree to minutes of previous meetings
  2. check RIC-95 status. Quite a lot of work. Code review and unit test cases still to be done.We quickly discussed a possibility of doing healthcheck also via a healthcheck E2SM that woudl have to be defined by O-RAN WG3. We discussed this because in the RICAPPSs Hello World xApp an non-standard E2SM does something similar. Current expectation is that WG3 work will not be picking up this E2SM any time soon.
  3. Check for Bronze what we achieved and Cherry-R5 plans: link (check under "Status 2020-04-29 and 2020-04-30 and 2020-05-06 and 2020-05-12")
  4. Rittwik wants to talk about Cherry release planning.
    1. TS use case will probably be expanded on // possibly some ML model management aspects for RIC platform
    2. Rittwik mentioned more work in O1/O2, but for Cherry-R5 we might have issues with standardization not ready yet. More likely Cherry-R6 content.
    3. For scalability on E2AP no plans in R5 because of standardization being blocked. We do have work for xapp scalabilty study in Cherry-R5 and benchmarking planned for Cherry-R5.
  5. We might or might not have to cancel the next meeting due to overlapping workshop. I will update the groups.io calendar if it's cancelled.
  6. postponed items (out of Bronze): RIC-76 (subscription manager) and many more - see Cherry-R5 plans (same link as in (3) above).

2020-04-28

Recording: near_rt_ric_platform_project_meeting_2020_04_28.mp4

  1. Review and agree to minutes of previous meetings
  2. FYI RICP (combined with RICAPP) demos are every third week: Sprint demos
  3. Status of
    1. RIC-95 (design approved by tel aviv teams // implementation should be ready // problem with testing as no access to simulator) Tel Aviv cannot test with proprietary simulator as no time. This might delay RIC-95 further. Harry cannot help as on leave. Ron might get simulator ready within two weeks, but there is some risk that service query is not working yet in simulator. Arunkumar could take a look at the service query support in simulator during next week once RIC-95 is ready. If we make good progress, we could still push this into maintenance release (after TOC approval).
    2. RIC-203 no progress. design not clear yet. Drop this from Bronze (not try to push it into maintenance release)
  4. postponed DB items EPICS: (not even started):  RIC-123, RIC-107, RIC-118 and RIC-119 as well as user story: RIC-104 to post-Bronze-R4
  5. 2020-04-28: epics still open team 1: 17, team 2: 5, team 3: 3, team 4: 8 : team 5: 10, team 6: 2, team 7: 2. sum = 47 still open
  6. FYI: Tommy Carpenter has left the project. Committer upgrade needed. A1, xapp-frame-py → Chris Lott. RMR python version is in xapp-frame-py. RMR also replace tommy with Chris (even if no RMR python work a<nymore), Rpanta also remove from RMR repo. The repo "utils" we should remove. Add Chris now. Remove Tommy after Bronze. Thoralf to initiate this change.

  1. Review and agree to minutes of previous meetings
  2. Between "DBAAS" single-instance and "HA" we switch by using same configmap with different content as in this review: https://gerrit.o-ran-sc.org/r/c/ric-plt/ric-dep/+/3105 For platform components this is a good solution. The idea is that xApps (if they use SDL) have something similar. We might have to expand how this works for xApps later on, e.g., so that xApps have a way to declare what they need in terms of data storage.
