NONRTRIC (John Keeney)

• Maintenance I-Release
  • Running out of time ....  unlikely to make the release vote planned for this week TOC call:
    • A1 compatibility between A1-PMS and near-RT-RIC A1 Mediator
    • Service Manager - first version
• Continue work on rApp Manager - as a focal point for tying together alot of other existing activities
  • Working on some sample rApps. e.g. See Release J: Simple rApp using Hello World Microservice
• Continue work on Service Manager - again pulling together alot of work on Service Exposure in previous releases
• Continue maturing the A1-Policy Controller function (ref ONAP) - including a potential new NBI (v3) to achieve R1 alignment
  • Current API will be maintained but deprecated for several releases to come.
• Will need to de-prioritise many of the older less-used NONRTRIC functions - we welcome others in the community to help take these on if interested.
  • Need to study how/if we can achieve R1-DME alignment. Specs continue to diverge from our implementation - with alot of effort need to align.  We welcome contributors to help here.
• Working through reviews for changes to it/dep charts. Main focus on A1-PMS configuration functionality & state. Still verifying

Scalability in NONRTRIC DMaaP Adapter (Deena Mukundan guru raja John Keeney)

• Developed a fix for DMaaP adapter stopping & not re-trying. Will propose change to community.

• What is the role of the external auth callout (e.g. to OPA) from inside the service - why not just use Istio Policies (including perhaps callout to OPA)?

  • John Keeney These callouts are optional - if external call-out endpoint is statically configured.
    

    • Ref: info-job-authorization-agent: in Sample config application.yaml

      • (Efficient if endpoint is deployed close to ICS, e.g. a sidecar) 

    • Format of callout: https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-informationcoordinatorservice/en/latest/ics-api.html#tag/Authorization-API 

    • Allows more fine grained access control (e.g. ABAC/TBAC or checks where app state is needed) which Istio Policies will struggle with,

    • Can be used in addition to or instead of Istio policies.

• Outstanding questions:

  • Ref Powerpoint from 2 weeks ago: 2024-01-30-ScalabilityinNONRTRICDMaaPAdapter

    • What is the purpose of jobgroup in code?

    • Why is Dmaap-Adapter having a Stateful-set chart when Dmaap-Adapter is stateless?

  • Will take these questions off line as we need to investigate a little
