NONRTRIC (@John Keeney (Ericsson EST))

• OSC NONRTRIC: Release J

• Continuing tasks as mentioned previous weeks. 

  • Continue work our new Service Manager function

    • Improving Documentation & deployment scripts etc

    • Lots still to do! Backlog will continue into next release

  • 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

    • 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.

    • Making slow but steady progress.

      • First version of R1 API implemented

      • Lots of work on testing & benchmarking & documentation

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

    • No update from near-RT-RIC team

  • 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.

• Continuing work to refresh simulator's base platform for O1

  • Will mostly happen in Release K
