Discuss Slicing impact https://jira.onap.org/browse/DCAEGEN2-3021  & open items from 2021-11-30 DCAE Meeting Notes

E2E_Network_Slicing_DCAE impacts.pdf

Followup needed on below items (to be continued on next meeting or schedule separate call)

•  1) Specifics on ML MS  - Ahila P  

• • • Example on current training and configuration derived
    • Dependency/Interation with other ONAP components (e.g Policy, AAI) and Jakarta impact to be clarified
    • Training algorithm employed
    • Demo on how the ML MS is used on Slicing usecase flow will be useful

  Need to assess how/what source will be maintained in ONAP and can be supported in generic before it can be standardized as MS under DCAE project

•  2) DCAE Impacts from CCVPN/IBN usecases any (outside of above ML/MS) pending clarification Henry Yu 
•  3) SliceAnalysis API changes to be finalized by M2 (swagger definition preferred)  - Ahila P

**Deferred to next meeting**

Discuss DCAE transformation planned items for J release - DCAEGEN2-2773

Priorities

• Switch components to latest SDK version
• OOM charts updates to disable Cloudify/handlers (CBS may be exception depending on above item)
  • Iteration 1 (once OOM branching is done)- Disable all cloudify/handlers under dcaegen2 
  • Iteration 2 (M3/Jakarta)- Move VESOpenAPI and CBS? to dcaegen2-services 
• Integration testsuite migration
• Helm flow support through MOD 
• DMaap Provisioning optimization
  • Pub/sub credential handling alignment - OKAY to proceed 
  • Topic/Feed cleanup on undeploy -
    • Topic cleanup to be split into separate Jira and assessed later ; Feed cleanup OKAY to proceed. (Impacted by AAF removal, Strimzi Operator introduction)

• Fiachra Corcoran  indicated DMAAP team looking to build a standardized library for Strimzi/Kakfa migration across ONAP components-  to be confirmed in few weeks. Will hold on DCAE SDK standardization efforts across DCAE MS for time-being.
• PM-Mapper migration for switching to unauthenticated topic to be targetted for J release (SDK DMAAP integration is optional, but preferred). To bo be discussed with Tomasz Wróbel / Remigiusz Janeczek  to finalize plan.

• SliceAnalysis/KPI-MS will remain on Cambri lib

• and will subscribe to PM_Mapper unauthenticated topic

Followup with Fiachra Corcoran /DMAAP team on below

• Any solution to provision unauthenticated  topic/client in DMAAP MR currently part of ONAP deployment?

Currently most of unauthenticated topics (used by DCAE MS) are created on the fly (i.e during first event published). However this causes an issue for MS Client/consumer as they miss the first event (as client gets registered in kafka only after topic is created). This may be required for BulkPM Testsuite/SliceAnalysis/KPI-MS when PM_Mapper is switched to unauthenticated topic.

• Assess

• if DMAAP SDK client lib can be adapted

• to support Strimzi/Kafka and used as common target library
• HV_VES currently uses direct kafka interfaces; suggestion on how this should be handled part of Strimizi/Kafka migration - if any recommendation on the library to be used or change HV_VES kafka api's directly?

• Servicemesh support - DCAE component impact on below 

1. 1. Allow http support (early J release) - DCAE components that rely only on HTTPS will be impacted
      1. Partial analysis completed; impact limited to 1-2 MS currently - will share the report into WIKi/next meeting - Vijay Venkatesh Kumar 
   2. Components dependent on AAF cert 
      1. DR depenency on AAF is primarily on cert (auth is done local)
      2. Share the current findings and create wiki to capture the dependencies for DCAE components - Vijay Venkatesh Kumar 
   3. Secure topic/feed dependency - DFC, PM-Mapper, PNF-Reg, SliceAnalysis, BBS-Ep

• Impact from DMAAP-MR → Strimzi/Kafka
  • Pub/sub API change - may need to integrate with new SDK provided by DMAAP team; all DCAE MS will have impact to align with new SDK.
    • SDK client lib need to have backward compatibility with MR (controlled via ENV/deployment property)
  • Mapping service - Alternate solution proposed by Fiachra Corcoran /DMAAP team could be candidate solution; avoid technology dependency and can be handled generic across all MS without much impact
  • Provisioning API will change - DCAE helm template job MR provisioning template/scripts to be revisited under Strimzi/Operator
