NONRTRIC (@John Keeney (Ericsson EST))

• OSC NONRTRIC: Release J

• Preparing for OSC meeting/workshop at  ONE summit, and at LFN DTF at the end of Apr.

• Continuing tasks as mentioned previous weeks. 

  • Continue work our new Service Manager function

    • Still working on deployment, tests & integration

    • Docker:   o-ran-sc/nonrtric-plt-servicemanager  https://nexus3.o-ran-sc.org/#browse/browse:docker.staging:v2%2Fo-ran-sc%2Fnonrtric-plt-servicemanager%2Ftags%2F0.1.0

    • JIRA: NONRTRIC-944: NONRTRIC - Service Exposure Manager - Release J (& early K)DonePreview

    • Lots still to do!

  • 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

    • Aim to have an updated version in coming weeks

    • Working on SME & DME integration & improvements

  • 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.

    • New API development ongoing. May be some questions for R1-A1-P spec in March train ... TBC

  • Trying to consolidate deployment charts and scripts - currently have multiple versions, with some inconsistencies/differences. Will be ongoing for some time.

  • Still need to get working on a proper A1-Policy Integration test with OSC near-RT-RIC (A1 Mediator)

  • 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.
