11-25 (Today's Agenda)

  • Infrastructure
  • Mixed Licenses
    • Apache 2.0 uses more restrictive language than MIT, but they are roughly equivalent
    • Document in README (probably sufficient at the "GitHub organization README" level)
  • SD-Core
    • Currently addressing issues related to new golang dependency versions
      • Newer golang dependencies require semver format for the go module (i.e., go 1.23.0 instead of go 1.23)
    • Significant progress on 3GPP release upgrade (release 18): All NFs are now with release 18 for the SBI
      • Several issues to address such as callbacks, replace some structs that were removed in newer 3GPP release, among others
  • SD-RAN
  • OnRamp
    • Blueprint for "Multi-Hop Access" network released
    • A student working on service monitoring; just opened a PR
      • General idea: eliminate per-NF monitoring; always go through metric_func

3-4-25

  • Infrastructure
  • SD-Core
    • New Helm Charts were released (version 2.2.2)
      • Fixes (avoids) 100% CPU utilization
    • 3GPP Release upgrade (release 18)
      • SMF: Addressing issue with multipart response message
      • NRF: Addressing missing callback
    • How to deal with multiple licenses; e.g., MIT & Apache (ask for LF advise)
  • SD-RAN
  • OnRamp
    • Reviewing latest PR with 2.2.2 upgrade.
    • Discussion about scope: Ease learning curve or industrial strength ?deployment robustness
    • Testing Infrastructure assumes OnRamp itself is relatively static
  • ARA
    • Discussion with Serdar Vural from Canonical about Charmed Aether SD-Core

2-25-25

  • Infrastructure
    • GitHub Actions
      • Eric Update: ROC release and reusable workflows: After speaking with one of my colleagues last week who does a lot of work on our reusable workflows, I rearchitected the helm release to have most functionality outside of the workflow, where pretty much any action that needs to be taken is called from a small, discreet "micro-action". The result is workflows that are far cleaner, and having each bit of work in its own action allows for much clearer documentation. Even if it's still at a WIP point, I'll push my code later so folks can get a look at it and provide feedback.
    • AWS Images
      • will create a new aether-packer repo for VM spec
      • plan is to support 22.04 and 24.04; likely to deprecate 20.04
      • Eric Update: I've got code-based, reproduceable builds of Ubuntu images for Jenkins up and running. I'm currently testing the produced AMIs with this job: https://jenkins.aetherproject.org/view/all/job/Aether_OnRamp_Manual-test/. It looks like the most recent attempt failed due to a missing key. That may actually be something that needs to be changed in the job, since the best practice would be to have the key stored on the Jenkins server rather than embedded in the image.

      • Should just work
    • Support AF_PACKET mode in helm charts to enable E2E tests in GH actions (Ghislain)
      • Working towards e2e tests for PRs
      • May run into "GH runners" limitations and need Jenkins involvement
      • If this proves to be the case, existing Jenkins "Quickstart" job is close (e2e gnbsim+sdcore)
        • would need to modify to work on candidate images

8-20-24

  • SD-RAN
    • Working on v1.5 release
      • Working on documentation and release notes
      • To include OAI 5G RAN 
        • includes "ONF" E2 agent (not OAI's)
        • implies need to rebuild OAI images (since E2 agent is statically included)
      • Not include update to golang 
      • Expect announce 1st week of September
      • E2SM → Will add O-RAN RC Service Model 
        • Backward compatible with the old ONF Service Model
  • Infrastructure
    • Jira
      • Production site available at https://jira.aetherproject.org
        • Still working out Anonymous creation of issues
      • Permission Question:
        • Currently four levels of access
          1. Anonymous (users without Atlassian accounts or not logged into them) can Browse and Read existing Issues but not modify anything
          2. Any Logged in user can basically change almost any field in an issue, and invite people to join the site and become a user
            1. When invited, specific domains are automatically approved when invitee makes the request
            2. Basically, any  TSC user's domain (that is NOT public (ie, not gmail, yahoo, aol, ...))] is currently automatically approved.
          3. aether-jira-admin users can update group and user permissions
          4. admin can do anything.
        • QUESTION: Any need now to restrict (beyond being logged in as an approved Aether Jira user) things like:
          • Transitioning a ticket between states (including closing)
          • Mucking with assignee
          • editting fields beyond comments
          • → Taking a wait-and-see approach
      • Known TODOs
        • Figure out how to let Anonymous users create new tickets
          • Currently looks like a separate form to embed on an appropriate webpage that will then go create a ticket based on provided input
        • TST Guidance: Lowering the barrier to creating a Jira account >> creating Anonymous Tickets does not need to be supported
    • Confluence
      • Test migration appeared to complete successfully
      • QUESTION: Can I perform the formal migration from existing Confluence DataServer to Confluence Cloud between 12:00 noon Wednesday(8/21) and 12:00 noon Thursday (8/22) (PDT)?
        • Will require read-only Confluence installation at start of process until completion.
        • Upon completion, existing wiki.aetherproject.org will point to new site
          • Previous site will be maintained for approximately 30 days as an archive/reference site and then hopefully deleted.
        • I would hope that people can spend a 30-60 minutes reviewing the site after completion and ensuring things look okay.   Hoping to have acceptance of new site by next week's TST.
        • Post note on migration to #aether-dev channel
    • Jenkins
      • No progress as yet

...

  • Aether Jira Proposal:  Aether Jira Proposal
    • Tweaked proposal and accepted as "good enough to get started"
    • Should be ready to play with next week
  • Github org renaming: https://docs.github.com/en/organizations/managing-organization-settings/renaming-an-organization
    • More representative → Mostly focused on "opennetworkinglab" (should be "aether")
    • May break external links, but now is a good time to change since we're creating new docs/pages
    • No objection...
  • Slack vs Element (https://element.io/)
    • Limiting history to 1 year (affects "grandfathered" workspaces like onf-community)
    • Proposal: prune onf-community back to "aether" and accept history limit (take up with voltha and p4)
  • Code of Conduct ((https://lfprojects.org/policies/code-of-conduct/)
    • Look through the LF standard and decide at a future meeting

      • Actions that run for PR (ROC done)
      • Actions that run for PR (SD-RAN done)
      • Not yet publishing new Docker images (in progress)
    • OnRamp Integration tests
      • JJB Related: Jobs with same name as the one created earlier, are not getting created again.
      • Native Tests: All the Jenkins jobs are not able to go beyond aether-5gc-install step. → "new group" command hanging
  • omec-pod-init and omec-cni repos Gabriel Arrobo 
    • These repos are in Gerrit → Why? Not updated in years. Move to omec GitHub? → Yes.
  • TST Meetings in July → Will remain on the schedule and expect them to happen (with some people missing)

  • DCO (instead of CLA) in place Larry Peterson David Ferguson (Deactivated) 
  • Configuring new Jira Larry Peterson  David Ferguson (Deactivated)
    • Archiving old Jira
    • Proposal
      • Projects: SD-Core, SD-RAN, ROC, OnRamp, Smart5G
      • Workflow: New, Assigned, Resolved, Reopened (start simple)
      • What Fields: Description, Status
      • Hopefully will demo at next week's TST
  • GitHub default branch should be main instead of master. Ajay Lotan Thakur 
    • Master is old way; main is the new way (and the default)
    • Prefer to have all the same; most currently master
    • Decision: leave it as is (expect to be mixed)
  • BESS-UPF Helm Charts: Current charts assume symmetry for the access and core interfaces (i.e., same CNI Plug-in for both) Gabriel Arrobo
    • Any objection about making the Helm Charts as generic as possible such that each individual CNI can be independently chosen?
    • Example: access=macvlan, core=host-device
    • But it remains the default that they are the same (currently macvlan); so remains backward compatible
    • Will eventually want to expose in OnRamp
  • Road map cleanup Ajay Lotan Thakur Gabriel Arrobo 
    • Priority to take up only SBI upgrade this quarter/end of Sept 2024
