NONRTRIC (John Keeney)
- Work ongoing - as per last week:
- RAN PM functions - tidying up & re-releasing in maintenance release.
- Working with AIMLFW project: Joseph Thaliath to use newer versions
- Making good progress on rApp manager. More in coming weeks
- 3PP dependency updates & addressing vulnerability
- OpenAPI-first in A1-PMS & ICS
- Change from code→openapi→docs to openapi → code-stubs & docs
- To better align with R1 specs as they mature
- To improve expressivity of docs etc.
- Issue with test framwwork
- underscore in URI hostnames - introduced by docker-compose (v1)
- Some changes in A1-Mediator in near-RT-RIC plt in H-Release.
- Further investigation needed re effects on A1-PMS/ICS & A1-SIM
- RAN PM functions - tidying up & re-releasing in maintenance release.

OAM (Martin Skorupski)
- Looking at Netconf "Yang Schema Mount" for O-DU/O-RU relationship (WG5 yang models)
- making some progress ... more to come
- Request (from RSAC) to make proposal for RAN PM streaming
- See below
- PM Streaming
- Working with team in T-Systems to update ONAP VES collector to work with native kafka.

PM Data Streaming (Martin Skorupski & All)
(Recording timestamp @ 10:30)
O-RAN OAM spec refers to 3GPP specs to use websocket for transport
Data serialisation format options presented by 3GPP: Ref sect 11.5 TS 28.532
- Suggestion to do 3gpp-XML→yang→GPB ...
- Refer to "establishStreamingConnection" operation, table 11.5.1.1.2 "streamInfoList" input parameter where PM stream job is defined
- But how will the SMO terminate streams, parse, and distribute the data?
- Proposal
- SMO needs a Websocket stream terminator (e.g. to: S3 bucket, or Kafka?)
- SMO needs a GPB data parser (to: XML, or JSON?)
- <a big gap - for further study>
- Alot depends on the data characteristics & scalability concerns
- Then re-use NONRTRIC RAN PM functions so rApps can subscribe to filtered PM data in JSON format in Kafka and/or InfluxDB
- Need to read-up some more and come back to this in future weeks.
- Need to clearly demonstrate if there is a benefit beyond file-based PM and/or streamed trace data.
- e.g. shorter reporting period (ROP) file-based?
- Very significant scalability challenges as reporting period decreases, network function increases, job count per function increases.
- Proposal
Questions / Comments / AOB:
- None this week.
