4-1-25 (Today's Agenda)

  • TST Meeting Schedule

    • Should we meet every other week?

    • Change to every-other-week; next meeting on 4/15

  • Infrastructure

    • AWS images → Done

    • GitHub Actions

      • Not much time put into this for the last couple weeks (on ONOS Project)

      • Now reusing workflows on SD-Core (see below)

      • Could have onosproject reference omec-project workflows, but this implies a dependency

      • Plan: replicate the workflows (rather than reference)

    • Revisit registry proxy configuration → Aether registry replicates images in Docker Hub

      • So best use case for proxy is non-Aether generated images

      • Referenced by onramp/vars files and various value override files.

  • SD-Core

    • Move codebase to GO 1.24 (due to dependency requirements)

    • Move golangci-lint to version 2

    • Update SD-Core Helm Charts to avoid Kafka to crash due to zookeeper not present

    • All GitHub Actions are now “centralized” using reusable workflows (github.com/omec-project/.github)

    • Configure all omec-project repositories (SD-Core) to use “ruleset” instead of “branch protection rule”

    • Canonical will work on a proposal to re-architect config5g

  • SD-RAN

    • Still issues (E2 connection update) SD-RAN with srsRAN

      • This is important for IL due to a project we are working on.

      • If not possible to make it work soon, we will move to use OSC-RIC

      • Working with Woojoong to get a fix

  • OnRamp

  • ...

3-25-25

  • Adjourned early. See Slack for any updates.

  • Infrastructure

    • GitHub Actions

    • AWS Images

      • Verify OnRamp-22.04-test and OnRamp-24.04 are the labels for the two new cloud resources on Jenkins

      • Verify that the current set of jobs run successfully on 24.04.

  • SD-Core

    • ...

  • SD-RAN

    • ...

  • OnRamp

    • Merged several blueprint patches

    • Ready to re-sync OnRamp?

    • Will update Jenkins to use latest AIM images (and decommission 20.04 tests)

  • ...

3-18-25

  • Infrastructure

    • GitHub Actions

    • AWS Images

      • Final testing of images (Ubuntu 22.04 and 24.04) → Some failures with Quickstart and amp tests

  • SD-Core

    • Consolidation of GHAs:

      • Repo github.com/omec-project/.github

      • PR is under review

    • Should we archive old images as recommended by Docker Hub?

      • Gabriel will take a look at the organization settings to see if there is a way to define an archiving policy

  •  

    • ...

  • SD-RAN (Gabriel)

    • srsRAN has added "E2 connection Update failure" as a response to an "E2 connection update received from the RIC, but...

      • SD-RAN still expects to receive "E2 connection update acknowledge"

      • We were asked to use a different RIC (i.e., OSC RIC) if this issue cannot be resolved

      • They are interested in "testing" xApps from https://www.5gsec.com

3-11-25

  • Infrastructure

    • GitHub Actions

    • AWS Images

  • 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.

      • In progress → One for Ericsson radio and one for OAI radio

      • Could include ARA-specifics (e.g., for UEs, including experiments)

      • Intent is end-to-end deployment blueprints

        • related to OnRamp releases since more blueprints => higher hurdle

        • Need "owner" for every blueprint; some may be "core" and others "auxiliary"

      • 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.

  • SD-Core

    • Check with Ajay again about an SD Core deployment mode (below)

    • Status update:

      • Removed in gnbsim dependency from the CommonConsumerTestData. There were a few functions calling the CommonConsumerTestData  but these functions were not used. So, CommonConsumerDataTest  repo is now archived

    • golangci-lint not detecting all issues. For example, staticcheck  is enable in golangci  and it successfully completes. However, if we run staticcheck  by itself, it finds several issues that are not found through golangci 

    • We use logrus  (https://github.com/sirupsen/logrus) for logging, where the last commit is from June 2023. This might mean that the project is inactive (none is actively maintaining it). Based on this, I explore a few options and zap (https://github.com/uber-go/zap) seems to be a good alternative. As per its description zap is "Blazing fast, structured, leveled logging in Go". My suggestion would be to replace the logger. What are your thoughts? If agree, who can volunteer to work on this?

    • It would be good to check whether golanci-lint catches issues when using zap

    • GitHub Action (or Jenkins job) to run E2E tests for PR verification/validation

      • This could mean the use of a simplified version of AiaB

    • Bring omec-cni  and omec-pod-init from Gerrit to GitHub (omec-project organization)

    • A "Scalability" PR is in progress

        • Ideally, request production migration next week's TSC

        • Upon approval, site will be offline approximately 4 hours

        • No functional changes anticipated.

  • SD-Core

    • Should the sdcore-helm-charts work "out-of-the-box"? That is, should the users be able to deploy the SD-Core by running "helm install" command without having to use/rely on Aether-OnRamp (or AiaB)? [GA]

      • There are somethings need to be modified first e.g. UPF is deployed in DPDK mode default (most performant)

      • It depends on your hardware - there are a number of pre-requisites for this.

      • AiaB and OnRamp deploys in AF_Packet mode (in additional values file)

      • Q for Ajay & SD-Core team - should the chart use AF_Packet by default - we should strive for a positive experience when bringing it up regardless of method

    • Moving towards SD-Core 3GPP Release 18 (Gabriel)

      •  Implementing on SD-Core Roadmap

      • Executing on parts 1.a and 1.b among others

  • SD-RAN

    • Release 1.5 - in Aug with no dependency update - it is too much tightly coupled with other ONOS components especially for onos-api. (WK)

      • SD-RAN components are on Go 1.17 to 1.19

      • Option 1

        • Continue trying to update everything. This is becoming increasing difficult because of common dependencies

      • Option 2

        • Can we separate SD-RAN ric from uONOS under Aether or separate Github workspace? - in that case, we could say SD-RAN inherits a design/code from uONOS.

          • While doing that, fix e2sm and add new ransim.

          • Prevents breaking other components

      • Woojong will talk with Larry after SD-RAN 1.5 release to try to make a decision

      • LF wants to consolidate around SD-Core - the core of choice for LF (replacing Magma from Meta which is waning)

      • 5g-superblueprints are very broad in scope

        • Many different topics e.g. Edge, Cloud

      • We should try to package a proposal on embedding SD-Core (and Aether OnRamp (as a blueprint)) in to these 5g-super-blueprints and present this to LFN TST

  • ROC

    • Continue updating Wiki on the update of ROC model (Sean)

6-25-24 (Topics for This Meeting)

  • 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

  • Jenkins Status

    • ONOS GitHub Actions

      • 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)

6-18-24

  • DCO (instead of CLA) in place @Larry Peterson @David Ferguson (Deactivated) 

    • See Org README here: https://github.com/opennetworkinglab

    • Will current ONF/CLA be removed from the repos/checks? @Gabriel Arrobo 

    • Add more helpful info about DCO so new users know what do to.

      • Org README should explain and link DCO.

      • @David Ferguson (Deactivated) to look into "augmenting" the error message

  • 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 (Deactivated) 

    • 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 (Deactivated) @Gabriel Arrobo 

    • Priority to take up only SBI upgrade this quarter/end of Sept 2024

    • Dueling Docker installs → Ansible playbook now checks for existing Docker, per Docker best practices

    • Check that multiple gNBs work for data plane

    • Working on proposal for incorporating scalable Core into OnRamp

  • QA Update @Kunal Kapoor 

    • JJB code commit is done

    • Working on updating Readme and streamlining the code as per the current requirement.

  • LF ticketing systems (see above)

  • CLA issues: User does not receive confirmation email to complete process (https://github.com/omec-project/pfcpsim/pull/84#issuecomment-2113633448). Additionally, CLA message points to a link that does not exist anymore (https://wiki.opennetworking.org/x/BgCUI) [Gabriel,Woojoong]

  • UPF, DNN, Device Group Question

    • Current open issue: https://github.com/omec-project/smf/issues/227

    • DNN is being used as the primary key in SMF

    • It is possible at the moment to represent an invalid state

      • What direction should be taken to ensure data integrity / How should this be prevented?

    • Ajay looking at issue. Canonical will help fix.

  • QA

    • All the integration test jobs are fixed 

    • Single server UERANSIM blueprint - in progress

      • 2-server config test is successful.

      • Interest in reporting throughput test results (around 800Mbps)

      • UERANSIM blueprint documentation needs to "match" what Jenkins tests

    • Next big task: move job definitions to GitHub

4-09-24

  • Status of SD-Core /  OnRamp release

    • Version 1.0.0 of SD-Core Helm Charts published (called v1.4 of SD-Core)

    • Candidate branch of OnRamp 2.2.0 passing integration tests (plan to merge later today)

    • Release Announcement in progress

  • Registries: opennetworking.org is a mirror, but is referenced by OnRamp (to be fixed before "official" release)

    • Should use aetherproject.org registry

  • SD-RAN Update

    • Recruiting PhD students to work on SD-RAN

    • Sync'ing up with Gabriel an use of GitHub actions (waiting on DAF)

    • Reminder: Take a look at SD-RAN wiki pages

  • Is it time to form Working Groups?

    • Perhaps: SD-Core, SD-RAN, Trial Deployments (or Use Cases)

  • Proposal: Move Aether-related docs to GitHub pages (freeing up AWS server that is currently being used)

    • Minimally, need to move sd-core/sd-ran docs to aetherproject.org (currently opennetworking.org)

    • Bring gnbsim docs to the set of Aether docs

  • https://wiki.onosproject.org/ is down again?

4-02-24

  • SD-Core / OnRamp release status

    • New images, Helm Charts, docs published

      • Automated through GitHub actions

      • No CI dependencies on Jenkins (SD-Core is done)

      • Also applying to other components (see below)

    • Candidate branch of OnRamp now testing

      • QuickStart blueprint passes integration test

      • Other blueprints still being tested

    • Announcement Plans

      • Obvious new channels → email, slack 

      • Can use ONF channels, but should be pushing people to the new channels

      • Timon and Larry to work up a broader plan

  • Roadmap for SD-RAN & upcoming v1.5 release

    • (See Wiki for more info)

    • Roadmap page and v1.5 release pages (proposal stage) now on Wiki

    • High-level goals

      • Catch up with latest Service Models, etc.

      • Grow the SD-RAN community

        • Recruiting PhD students

        • Possibly engineers with companies contributing to SMaRT-5G

      • Stablize new RANSIM

    • SD-RAN Release Process → Moving from Jenkins to GitHub Actions

      • Testing, creating images, unit tests, check license done

      • What's missing is the publishing-related actions

      • Also many backlogged issues

  • CI shift (Jenkins → Actions) ROC is in progress → Same done for ROC, except PRs are still pending (Jenkins issue)

  • Action for inactive PRs and issues in repositories (Gabriel)

    • https://docs.github.com/en/actions/managing-issues-and-pull-requests/closing-inactive-issues

    • https://fvsch.com/stale-bots

    • Ongoing vs One-time??

      • 140 total, but only 15 are related to 5gc

      • Other 125 issues are related to 4gc

    • Discussion: Interest in maintaining 4G variant of SD-Core

      • Don't archive it (people do use it)

      • No one actively contributing

      • 125 open issues (plus other bug fixes not yet submitted)

      • Add "we are not actively maintaining 4g" comment and close the issues

      • NOT archiving, so someone can pick it up and run

      • Still works as an OnRamp blueprint (using existing images)

      • SD-RAN still works with 4G (using existing images)

    • What about stale-bots for 5gc?

      • Currently there for 30 days; increase for 120 days

  • Registry locations (aetherproject, DockerHub, opennetworking) (Gabriel)

    • opennetworking registry seems to mirror DockerHub

    • Do we need to still publish images in opennetworking? What is the future for the opennetworking domain?

    • Wean ourselves off of opennetworking (both the registry and the DNS name)

    • General Note: Look for opennetworking.org usage and remove (check Docs!)

  • Status of UERANSIM Blueprint / QA Status

    • Changes in aether-ueransim repo - PR Raised

    • Changes in aether-onramp repo for the UERANSIM integration - PR Raised

    • Larry to review

3-26-24

  • Aether Mailing Lists now up-and-running

  • Status of SD-Core Release

    • Source code is ready for release

    • Automating tagging process (waiting on the ONF bot)

    • Replicating the VERSION approach used elsewhere in Aether → AMF is "demo" repo

    • Immediate goal is to "fix" Jenkins job to publish Helm Charts from GitHub rather than Gerrit

    • Long-term goal is to write a GitHub Action to auto-publish Helm Charts (replacing Jenkins)

    • With Respect to OnRamp 

      • Test "candidate" that uses the latest charts → Define a "candidate blueprint" and run nightly integration tests against it.

      • Upgrade OnRamp from 2.2.0-dev to 2.2.0 (previous was 2.1.0).

    • Announcement?

      • Message to announce mailing list (also Slack)

      • SD-Core Docs include Release Notes

  • Status of SD-RAN Release

  • Status of UERANSIM Blueprint / QA Status

    • 2-Server configuration is the expected default

      • 1-Server config is still problematic – data loop

      • To debug as Future Work

    • Changes in aether-ueransim repo - Done

    • Changes in aether-onramp repo for the UERANSIM integration - in progress

    • Nightly integration test added to Jenkins - in progress

  • A limitation of OnRamp is that running two Cores (related to how network is configured) can get confused. Include Bilal in a discussion of how to address.

  • LF Transition Update

    • Wiki → Live at wiki.aetherproject.org

    • Mailing Lists → info@aetherproject.org set up (not a list); others (tst, dev, announce) still in progress

    • marketing:

      • Can set up Linkedin page? Done for VOLTHA. Marketing in general is addressed by the Board

      • Aether board has to decide on how to apply budget for marketing

    • Other board funding opportunities:

      • Intern projects (could be budgeted by the board); also funded internships

        • unfunded internships?  In return, certificate of completion??

  • Asking for help

    • Is this a discussion that should be started in the new email forum, or is Slack better for this type of discussion?

    • Slack “loses” history, email lists typically have searchable archives

    • Once the mailing list is established, @Mark Beierl will kick off the conversation there.

  • UPF Performance Testing

    • Mark Beierl wants to look into trex and UPF performance testing

      • At one point ONF used "Packet Testing Framework" to stress test UPF (t-rex generates load)

      • Able to directly test UPF without any other components affecting the performance results (Intel Labs doing this manually)

      • Traffic Generator Intel Lab uses: https://github.com/gab-arrobo/upf/tree/traffic-generator

  • Request slot for presentation in 2024-03-19 TST meeting for Canonical’s Charmed Aether 5G Core (Mark Beierl and Serdar Vural)

    • Shooting for 20 minutes next week.

  • SD-RAN update (Woojoong)

    • Release plan -for v1.4

      • Targeting Q2

      • Woojoong is writing a plan (patterned after the plan for SD-Core)

      • Defining scope 

        • Major change is to use O-RAN Service Models

        • Hope to include first version of new scalable RAN-Sim

        • Alex notes the current ASN.1 encoder might not be O-RAN compliant

        • See OAI integration note below

    • Scalable RAN-Simulator - getting delayed

    • 5G OAI integration?

      •  Last Pronto demo:  OAI integrated with KPI xApp. (OAI 2022-w52)

        • needs to be released from Intel internal github repositories.  Would like to get in 1.4 if possible, but may be delayed

      • Intel Labs has separate OAI integration (OAI 2023-w27)

      • The Intel Lab changes should be merged into OAI official release; may be able to use that in 1.4 release of SD-RAN

  • QA

    • bubbleRAN (OAI commercialized stack)

    • Purdue → Modified SD-Core to demo scalability of CP

    • Princeton → Demo’ing how to monitor RAN activity

    • Intel Labs → Security & Slicing (that it used OAI is an artifact that can ber feedback into a blueprint for others to benefit from

    • Larry will set up skeleton for this on wiki (once wiki is up)

    • Others will flesh out the details.

  •

    • Research Platform → Purdue, Princeton, Intel Labs,...

    • Kajeet?  4G deployment

    • GSLabs +  monogoto

    • Next Step

  • Release Plans

    • In good shape; whittling away at PRs.

    • More than 200 PRs open (e.g., dependency updates)

    •  

      • Intel Labs has proposed some features (<10 PRs)

    • Have v1.5 release that was ready at one point.

    • Activity around RANSIM that’s related

    • Who!!!!!!

    • Action: Talk to Woojoong and see if he has a proposal

    • Questions: Archive SD-RAN RIC in favor of OSC RIC  (or Flex RIC)

    •  

      • Would need to fold OSC RIC back into Aether 

      • Flex RIC (OAI’s RIC) - but license might be a problem

      • SD-RAN RIC has advantages: Safe PL, cloud native design

      • Bit-rot will eventually make SD-RAN useless

    • Implies a set of “official” blueprints (which implies a set of Helm Chart

  •  

    • SD-Core

    • SD-RAN

    • Aether 2.2.0

  • QA Update

    • Few test cases are under testing phase

    • Currently local (need to move to public Jenkins)

    • Proposal : deploy a non-containerized UERANSIM on node2

    • Seems to be working ok (not tested on a single node, co-located with Core)

    • To create a Jenkins job to test (and demo)

  •  

    • gnbsim test framework 

    • UERANSIM integration

2-27-24

  • LF Transition Update (daf)

    • Impacts wiki too.

    • Certificate has been reset (this is a DNS issue)

    • Has no effect on services working

  •  

    • registry.aetherproject.org DNS resolution should be fixed sometime today.

    • AWS org had been transitioned as of Friday, but not today (looking into)

  • Guillaume to present proposal for tagging releases

  •  

    • Issue: versioning source for each NF vs versioning SD-Core in aggregate (including helm chart and container artifacts)

    • Also beyond SD-Core to include all of Aether.

  • Discussion about the process for tagging auxiliary repos (Gabriel)

  •  

    • Ghislain comment/suggestion: https://onf-community.slack.com/archives/C02TGUWTC93/p1708705492733279 

    • Yes to methodology Guillaume proposes / No need to stay in sync.

    • Historically tried to pin versions of dependencies (so builds repeatable)

    • No tag on every commit (had to change VERSION file), but the higher level module pins on a specific version, so if you want to incorporate an update, you need to change the VERSION. Developer judgment on when to update VERSION. CI mechanism does the right thing when the VERSION file changed.

  • DPDK Issues in the UPF (Mark B.) Background:

  •  

    • VM with 3 virtual interfaces, 16g ram/2x1g HP, 8 cpus

    • Setup dpdk on host for PCI ids 00:04 and 00:05 (2 of the virtual interfaces)

    • Start bessd, get error when running up4 script:
      EBUSY: Device or resource busy

    • Followup pointers from Gabriel, Dan, and Larry

  • Changing bitrate does not affect existing connections.

  •  

    • AI: Mark to open an issue.

  • QA

    • Added validations in the gnbsim integration test.

    • New framework : 33 out of 57 TCs are done (Robot-based)

    • Still seeing the issue (may be multi-NF version issue)

    • Updated webui container works better; release note has been posted; waiting for release instead of back-patching.

    • Runs in a container (apart from SD-Core/k8s)

    • Has a single interface for both control and data planes

    •  

      • Why is this a problem? A single interface works fine for others.

      • If it is a problem, is it unique to being containerized?

  •  

    • Create a more exhaustive tests for gnbsim : in progress

    • First UE failure issue

    • UERANSIM data interface connection

  • SD-Core wiki page down which causes the unit tests to fail in link check (issue observed while raising PR on sdcore-docs repo) (Suresh)​​ https://wiki.opennetworking.org/display/COM/SD-Core

  •  

    • ONF Wiki back up – system got corrupted, needed to be rebooted, resulted in changed IP so had to reset the DNS settings this morning.

    • Other option is to mark onf wiki as an “ignore” in conf.py (until we update docs with links to Aether wiki).

  • Aether-QA

    • Add a new integration test that “hardwires” in latest web console  image.

    • Issue is tunneling through docker container

    • Maybe look at gnbsim; how does it set up tunnel? Keeps control and user plane separate, whereas ueransim uses a single tunnel/interface.

    • Look to others that have set up UERANAIM in a separate server.

  •  

    • First ue failure → Need to update image we deploy (update helm charts in progress).

    • Iperf3 integration to ueransim

    • ROC re-deployment → No new developments to Aether-Jenkins repo on GitHub (include aether-ci-management “structure” in aether-jenkins).

Notes from earlier TST calls can be found here. Recordings can be found here.
