      1. Rittwik: Sent it to John Paul.  Action/ Rittwik: I will set up a meeting and pull together a team.
      2. Jack: It is difficult to move quickly.  It takes time to ramp up.
      3. Rittwik: Where should I put the challenge?
      4. Jack: Events wiki and post to the reflector.
   2. Lusheng wants to post the status of the Integration and Test 

5. Release Votes and Approval

   1. Vote on the Bronze Release and Integration and Test Status
   2. Jack: The press releases are handled by the O-RAN Alliance.  Zbynek is the primary contact and he runs it through the O-RAN Alliance.  Jinri is our interface to Zbynek.  Zybnek has pulled together a draft.  It will be combined with the Virtual Demo and the board meeting that is coming up at the end of the month.  The direction is to release the press release at the end of the month like June 30th.  That gives us another week for the highlights.  That is the feedback from O-RAN Alliance and Zybnek is our contact.
   3. Jinri: Does not have the latest.
   4. Trishan: Do we need a quote for this release?
   5. Jack: Yes, we should.
   6. Trishan: Jinri please share.
   7. Jinri: I'm not sure we can share but we can pull out a portion and share with this community.
   8. Jack: It is a combined press release making it a little complicated.  I'm trying to work through how this work than through the traditional open source.
   9. Trishan: If it is a press release we keep it close.
   10. Jack: If you have input contact Zybnek and he will coordinate with Jinri for the PR Release.  That gives us a little window to discuss.  Let us go on to the report from the system integration group.
   11. Lusheng: Sharing screen.
   12. Jinri: OCU PTL informed Jinri they have code ready for quite some time.  They are waiting for the repo to be opened by the LF.  The request was submitted one month ago.  It has been ready for quite some time.  
   13. Lusheng: I was cc:d on the help desk ticket.  LF has added all the information needed for the automation job to create the repo.  7 - 8 hours ago there was a message from LF that the ticket is on hold.  Action/ user-d3360 will check the status of the O-CU demo.
   14. Lusheng: Scope: We have a number of use case flows.  Mainly the flows are RIC , O-1, A-1 healthcheck.  O-1 was descoped.  Traffic use case is a partial flow that verifies the traffic steering decision.  First is without KPIMon.  Second phase in the Bronze maint. release will deliver the full flow.  O-DU high and low will communicate over FAPI and exchange one MAC message.  This is also timed for B maint. release.  For integration this is what we deployed for testing. The color coding represents different code implemented for different projects.  There are some pieces that are grayed out and will be deoployed in Bronze maint release.  We deployed two k8 clusters in the lab.  We deployed SMO real time one towards edge.  Status: We have completed two of the four flows A1 RIC healthcheck.  Long with more than 60 calls.  The long chain will interact with non Real Time down to A1 mediator and distributor to the Hello World xApp.  To support xApp near Real Time RIC complex flow passed.  
   15. Proposals for 4 flows deliverables.
       1. Lusheng would like to recommend option 1
       2. Lusheng requesting a vote from the TOC. 
       3. Jack: Floor is open for questions.
          1. Jack: if we go with where we are right now.  What percentage of work that's been tested.  All flows have not been tested.  There are only certain things that we can test.  It is driven by end to end flows.  When you say for the overall testing plan what percentage would you put on the testing overall.  What percentage of testing of flows will one week give you?
          2. Lusheng: We are between 80 - 90% Blocker is the alarm flow that is blocking the two healthcheck.  We are not able to complete the test however the dev teams were successful.  That is why I think it is a configuration mismatch and not a feature missing.  There is a feature missing but will be provided.  The one week extension will help us to complete the alarm process and we will have the 4 flows.  The alarm processing flow involves O1 mediator and Prometheus and Prometheus manager.  Prometheus are external components of the upstream so configuration is tricky.
          3. Jinri: if we can address can we include O-CU with the one week extension?
          4. Lusheng: The code will not be a part of testing. 
          5. Jack: Has the license scan been completed and accepted?
          6. Lusheng: Yes, LF attorney conducted a scan and came back with questions.  I distributed to the PTLs.  I have to pull that report and return to legal.  The issues have been resolved but we don't have LF legal final approval to release the code.
          7. Lusheng: We are putting together a Getting Started guide.  It is a work in progress.  We will have the test documentation and a video tutorial.  The video will be on the tutorial.  After the Bronze release will be off. the landing page.  The quick start will be for end users of how to configure and run.  What are the commands to run.  We have the first part all the way up to deploying near completion.
          8. Jinri: Have you considered a two week extension for safety?
          9. Lusheng: No I did not.  
          10. Jack: We try to stick as close to our schedule as possible because people will start moving into. the maintenance release.  We try to focus to validate through testing.  That is what is most useful to the software community vs. diving into code that they are not familiar with and they don't have a lot of support.  It's progress for the community but not for downstream users.  You still have to clean things up.
              1. finishing completing testing
              2. getting through scans
              3. make the getting started guide for people to understand what the Bronze release is all about.
              4. Let the team take on a host of issues for the maintenance release rather than working the team week to week.
              5. user-2057e agrees with Jack to complete in a week and clean up in the maintenance release.
              6. Ganesh and Juha agree.
              7. Jinri: The reason i raised the comment because I think O-CU is critical for the release.  If we have a two week window extension we can get the O-CU part done.  The code is ready and waiting to be uploaded.  If we can do it in two weeks we can include the O-CU.
              8. Jack: We should get it scanned and address the legal issues in time I doubt two weeks... It will either pass or need more time to resolve that will push into maintenance release.
              9. Jack: Martin Skorupski provide the status for the TR-69 adaptor is included.
              10. Lusheng: The previous scan did not include.
              11. Jack: Those are two items we should put on the list for the maintenance release.
   16. Vote: On motion by user-d3360 to move the Bronze release from 14 Jun 2020  to 21 Jun 2020 add one week extension to the Bronze release.  Delay the release by one week.
       1. Seconded by user-2057e
       2. VOTE: Vote taken, item passed
   17. Jack: Action/ Trishan: clear all the legal items for the code and figure out what is needed for the O-CU repo creation so the team can continue.
   18. Action user-d3360 provide Trishan with the O-CU repo trouble ticket.
   19. Action/ Jinri Huang generate an email to inform Zybnek and EC regarding that we will be delaying the release 
   20. Zhimin: We decided to release next week.  I have questions for development on the branch.  What is the way for us to implement.
   21. Lusheng: I will send out a separate email for the release and action items.
   22. Jack: For pieces that are complete as far as Bronze is concerned they can branch their code and move on to maintenance.
   23. Lusheng: Yes, the release process, 1 you need to make sure as PTL that the artifacts exist in release repo registries and not in staging.  2.  xApp descriptors contain a link to the docker image.  After that you can make the branch.  We will use the bronze branch.  All lower case for the branch name.  bronze will be the bronze name.  The repo owners can make the branch.  Please make sure the release notes in the repo docs section is up to date and contains the bug fixes in the release notes.  This is the high level process.  
   24. Jack: Everyone should update their bronze release table for features and capabilities so that it is on the web site as well.
