8. Standing Agenda Items (Brief Status of Ongoing Activities)
   1. Release Manager Trishan de Lanerolle /Release Planning: Weekly TOC Scheduling
      1. Project Bronze Release
         1. Rittwik - In the virtual F2F most of the projects met with their working group reviews.
         2. Jinri - Sees a gap in Cherry.  Overlap of WG.
            1. Jack - We have our ETE use cases that drive what we focus on in a release.  Right now we have two.  Traffic and self-test.  Think of it as something that is driving RAM functionality and OAM functionality.  Consider those and other tracks that are meaningful at pushing our community agenda.  The RSAC committee can provide the specifications that are changing in the window.  People that are interested please engage and help drive what are the important functionality.  C and D are important releases in delivering and driving value.  It is important that everyone get involved and the use cases in the C and D releases drive value to the O-RAN community participants and service providers otherwise we have to question whether we are going down the right path.  Please get involved and help us get there.  Let us see what we can do with the RSAC committee and see if our specs are frozen to make recommendations.
   2. Report out from PTL: Stand-Up & Report Out on Blockers - next week we will start to cover this list.  Are there any major items that anyone would like to raise to the TOC this week? 
      1. Matti Hiltunen RIC Applications (RICAPP)
         1. We are working on 6 xapps.  4 are traffic steering, 1 demo, 1 measurement campaign xapp.
            1. Is there a simulator requirement?
               1. Even if we decide to go with Viavi I don't think they committed to the E2 interface.
                  1. The strategy was to get offline data.  If that is available we can replay the E2 simulator.
                     1. Are there committed resources?
                        1. Alex - This is an open issue no one has volunteered.
                     2. How can we help?  Who can step up and work with Alex to get this critical part done?  Is Viavi incremental to this need?  Is it available in this time frame? 
                        1. Not E2, we want the metric that the EU and DU can provide.  
                        2. RAN simulation data is critical.  We can work the E2 delivery in parallel.  
                        3. Is the simulator critically needed or not?
                           1. If we are using the RIC platform and we use the KPI.  We say we are using e2 then we need the simulator.  If we by pass e2 and kpi mon then we can populate the SDL layer.
                        4. Jack - yes it's needed.  Is there anyone on the call who can step up and help in this space?
      2. Thoralf Czichy RIC Platform (RIC) 
         1. note I updated the committer change process as per discussion last week: How to request committer changes.
      3. user-a934b O-RAN Centralized Unit (OCU) 
      4. Sachin Srivastava O-RAN Distributed Unit High (ODUHIGH)
      5. Zhimin Yuan O-RAN Distributed Unit Low (ODULOW)
      6. Martin Skorupski Operations and Maintenance (OAM)
      7. Alex Stancu Simulations (SIM)
      8. Xiaohua Zhang Infrastructure (INF)
      9. weichen ni Documentation (DOC)
      10. John Keeney Non-RealTime RIC (RAN Intelligent Controller) (NONRTRIC)
      11. (TBD) O-RAN Radio Unit (ORU)
   3. user-59b16 Requirements Software Architecture Committee
      1. David Kinsey, Rittwiki, RSAC team discussed one Dynamic (performance mgt.)  data collection set agenda pushed to ONAP.  It is the responsibility in SMO.  There is no SMO project. We are submitting. 
         1. Action user-59b16 add Martin Skorupski to conversations around dynamic data collection.
         2. Is there a cutoff point this week for your requirements because the ONAP G release gate is closing.
            1. Rittwik - Yes, we are working on the requirements.
            2. Action/ user-59b16 send @John Paul Lane from Ericsson the RSAC requirements.
      2. WLF files?  Zhimin Yuan we are in the process. 
      3. Will that happen once we do the integration
         1. We are preparing for the Bronze relase.
   4. user-d3360  Integration and Test
      1. Plan for Integration and Test 
         1. We have one development sprint left.  First we will do integration in two separate groups.  
         2. ODU Low and ODU high and
         3. OTF, OAM, NONRT RIC, Near RT RIC APP, SIM (Cloud), INF, O-DU LOW, O-DU High, SIM (Bare metal deployment)
         4. Integrated testing is lead by each PTL.  Every project is delivering multi-containers.  They are expected to do their own integration testing.
         5. Pairwise testing requires a need to interact.  Next level is our use case testing.  We will have a working session call and try to run the integrated testing together.
      2. How we will execute (be mindful of automated cleaning process) 
         1. We have a Nexus Staging Docker Registry (images on this registry only live for 30 days) after that an automated cleaner will remove.  There are ways to regenerate but keep the 30 day limit in mind.  
         2. merge jobs are automatically run weekly, which keeps images fresh in the staging registry :)
         3. There is a container tag.
         4. Nexus Release Docker Registry.  Images on release repo live "forever".  Images on release registry CANNOT be overwritten.
      3. Lusheng proposing to formally adopt semantic versioning for tagging released O-RAN docker containers.  After passing the component communicate through wiki, lists, and jira.
9. New Agenda Items (New Business): New Items Submitted (+speaker) & Open Call to TOC For Additional Items. 
10. Planning for Next Meeting
11. Any Other Business (AOB) 
12. Meeting Summary (resolutions, new action items, etc.)
