- This week's TOC (in 2 days):
- Last week's TOC (Thursday):
NONRTRIC (John Keeney)
- Initial proposals for J Release are ongoing:
- Tentative headline goals:
- 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
- may be able to get an early alpha version released at I Maintenance Release time - running out of time on this.
- Continue maturing the A1-Policy Controller function (ref ONAP) - including a potential new NBI (v3) to achieve R1 alignment
- May need to de-prioritise some 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.
- Continue work on rApp Manager - as a focal point for tying together alot of other existing activities
- Tentative headline goals:
- Maintenance I-Release
- Running out of time ....
- Still have an issue with A1 compatibility between A1-PMS and near-RT-RIC A1 Mediator. Hoping to make progress & fix together with A1-Mediator team for Maintenance Release.
- Maybe Service Manager - TBC
- Running out of time ....
- Working through reviews for changes to it/dep charts. Main focus on A1-PMS configuration functionality & state. Still verifying
SIM (Alex Stancu)
- J Release Planning
- Will be updating at RSAC call: RSAC Meetings
- No new use cases or feature requests yet
- Thinking on moving simulator infrastructure form C++ → Python. Will hopefully help get more contributions
- Would like to move to later version of netopeer
- O-RAN spec alignment as features are added
OAM (Martin Skorupski)
- J-Release Planning:
- Issue with OAuth (ONAP London ++) - working on this
- Issue with Jetty → Karaf → ODL → CCSDK - Work ongoing
- Updating OAM controller & version updates
- Updating to ODL Potassium
- Update to Oct 2023 O1 specs.
- Working through issue with yang specs from Wg10, WG4, WG5

Scalability in NONRTRIC DMaaP Adapter (Deena Mukundan guru raja John Keeney)
- John Keeney Suggest using ranpm function in NONRTRIC rather than DMaaP Adapter for larger scale

- Proposal for streamed bulk pm - but not yet implemented
- Relationship to older work in ONAP?
- Work in ONAP is obsolete and unusable now.
- Abover OSC version is much more lightweight, but probably not as functional.
- Slides for discussion:
- DMaaP adapter is not very scalable - intended as a demonstrator of small scale VES or Kaftka filtering & re publishing as an ICS job (REST of Kafka)
- DMaaP Adapter - and by default all ICS producers - are designed to not be aware of other producers or consumers
- So load balancing is tricky
- Easiest way is load balancing by splitting workloads across multiple jobs/producers rather than replicating producers in a single job etc...
- Will continue discussions off-line -e.g.
- why are we using stateful sets instead of normal deployments? Combined with PVCs?
- consumers stops re-trying if failure: probably need to improved this.
- replication of ICS instances?
- what is jobgroup?
- Aggregated filters ... shown in image at https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-dmaapadapter/en/latest/overview.html#bulk-pm-subscription
- This just represents multiple independent filters from multiple producers all publishing into the same topic
- etc.
