OSC Project roundup

OSC Cherry Rapidly approaching! (Release early Dec)

NONRTRIC (John Keeney (Ericsson EST))

• Continuing with Cherry Release Prep.
• Plan to demo A1-Enrichment Function next week (will send invite to all here, discuss@o-ran.sc.org & add to ONAP & OSC calendar)
• Continuing pre-release with Integration & Deployment mainly.
• ONAP Guilin Release of A1 Policy Functions on track.

SMO (Mahesh Jethanandani)

• Yang validation tool function available in SMO gerrit, and Cherry Integration tasks continue pre-release.
• Demo first version CSAR Package Validation tool
  • Pawel Slowikowski Similar tools already exist in ONAP. Mahesh Jethanandani Tools is based on ONAP VNFSDK version with unnecessary parts removed
  • John Keeney (Ericsson EST) Tosca parsing tools available in ONAP. Ref Tosca Parser in Policy Framework (and SO).

SIM (Alex Stancu )

• Mahesh Jethanandani still working with Alex Stancu on wiki page etc Yang Validator (Netconf) client in OSC Lab.

OAM (Martin Skorupski )

• See video of OSC Cherry OAM (FCaPS functions) https://lf-o-ran-sc.atlassian.net/wiki/display/OAM/Use+cases+demonstration

ONAP - OSC

• Swaminathan S Added additional content to ONAP use cases page: https://wiki.onap.org/display/DW/Potential+ONAP+%3C-%3E+O-RAN+collaboration+use+cases - including the key JIRAs & people.
  
  • Former user (Deleted) For more info on these use cases refer to Use Case Realization Meeting Register MoM & attend meeting if desired.
• John Keeney (Ericsson EST) & All: Suggest we need a similar page in OSC (RSAC?) to discuss/assist collaboration from ONAP community into OSC use cases too?
  • Martin Skorupski Alot of what is used in OSC is downstream ... and most exists independent of OSC.

End-to-End use case in OSC

• John Keeney (Ericsson EST) Continued discussion from last week 2020-11-18 Meeting notes - Joint OAM / NONRTRIC / SIM / SMO SCRUM meeting
• Discussed some possible options (All need proper discussion later to check feasibility):
  • Front-haul-based
    • What creates the VES fault event when O-RU is brought down? (Mahesh Jethanandani & Martin Skorupski had some discussions with O-DU team ... still ongoing)
      
      • Can be created from O-RU or O-DU.
    • FM VES notification received via DMaaP to rApp. John Keeney (Ericsson EST) NONRTRIC team can create a simple rAPP to then trigger a O1 CM change via OAM controller (Sample Postman scripts are available).
    • Different options for O1 message: O1-CM to O-DU, O1-CM to O-RU https://oranalliance.atlassian.net/wiki/spaces/FHWG/pages/1092485360/WG4-2020.003+-+O1+support+on+the+O-RU+-+prelim
      • Multiple options might be best.
  • Near-RT-RIC (only)
    
    • Only pre-spec FM available in near-RT-RIC (To confirm with OSC nearRTRIC teams)
    • NONRTRIC rApp sends A1 message to near-RT-RIC. (Probably need an xApp to receive it)
    • John Keeney (Ericsson EST) & Martin Skorupski Need to talk to the rea-RT-RIC team in OSC
  • nearRT-RIC & E2 (More ambitious)
    • Could include O-DU (O1 source & O1 target & E2 target) ?

• • Use cases in ONAP may be useful, e.g. Slicing? OOM? (But need to be reported in OSC)
  • Possibility or re-using Samsung ONAP demo and making it publicly available?
    
    • Pawel Slowikowski - Can share, but an "official" usecase introduces alot of overhead in ONAP, need a repo, project. long term support. Would need to be properly landed in ONAP etc ....
      • John Keeney (Ericsson EST) Possibly an PoC - less requirements? Pawel Slowikowski Still needs to be landed somewhere.

Apps/Control-Loop/Automation-Loop in ONAP

• Pawel Slowikowski Where would the apps be? John Keeney (Ericsson EST) In OSC we'd call these rApps, Pawel Slowikowski no concept of rApp in ONAP ... or ONAP-App either!
  • John Keeney (Ericsson EST) PoC in ONAP Guilin & Honolulu TOSCA Defined Control Loop PoC in ONAP & TOSCA Defined Control Loop: Architecture and Design
  • Michela Bevilacqua Liam Fallon Possibly demo in coming weeks?  (TBC)
