Notes:

Housekeeping

• O-RAN vF2F completed.  https://oranalliance.atlassian.net/wiki/spaces/OAH/pages/1303937147/Virtual+F2F+Meetings+January+25+-+February+5+2021
  • Main topic was discussion for Min Viable Plan (MVP) for O-RAN across working groups
• LFN vDTF event finished https://wiki.lfnetworking.org/pages/viewpage.action?pageId=46106257

  • Martin Skorupski Swaminathan Seetharaman John Keeney Presented about this discussion/alignment group: 2021-02-04 - ONAP: ONAP/O-RAN/OSC Alignment - Updates and Roadmap (Slides, recording)

    • Good interest from LFN community but limited time for engagement.
  • (Also ONAP/OSC test/demo environment at LFN vDTF event today: 2021-02-03 - ONAP: Demo: O-RAN A1 Policy & Non-RealTime-RIC automated test/demo environment)
• Investigating if a different timeslot will suit better.
  • John Keeney Martin Skorupski Will poll community again for options.
  • Unfortunately we cannot find a slot that suits all interested parties

OSC Project roundup

NONRTRIC (John Keeney)

• Control panel re-engineering ongoing - backend mainly
  
  • To streamline API exposure for control panel
• Starting some prototyping around rApp execution platform & packaging.
  • Will present a more detailed proposal in coming weeks.

SMO (Mahesh Jethanandani)

• Mahesh has a scheduling conflict at this time

SIM (Alex Stancu)

• Working on Netconf call home over TLS (vs. SSH) - needed for proposed O-RU usecase.
  • Need a updated of ODL - beyond Aluminum (Silicon)
• New Simulator Alex Stancu
  • Extensions of NS3 models/plugins for RAN simulation
  • Facebook? & Berkeley ? Alex Stancu will begin joining calls
  • Very little detail at this stage

OAM (Martin Skorupski)

• Continuing to work on 2 main use cases:
  • Callhome to VES:pnfRegistration
    • Provide functionality to provide a VES pnfRegistration event in SMO for events that only support NetConf Call Home
    • Configure device to send call home event & cert management, mountpoint in controller, then listen for callhome & translate to VES event to VES collector
    • Some updates to the O-RU FH use case needed - to be discussed in RSAC
    • John Keeney Kamel Idir How does this interact with the ONAP Plug & play usecase? Martin Skorupski No effect, this enables the use case to work with functions that do not already provide the VES event pnfRegistration. No effect in controller - e.g. if the node is mounted again. 
    • Ref SIM topic above about call home over TLS - (Step #5 in call chart at Callhome to VES:pnfRegistration)
    • Vidhu Shekhar Pandey Call flow shown is for O-RU ... Similar needed for O-DU? Martin Skorupski No. Uses normal VES event itself. Vidhu Shekhar Pandey Already implemented? Martin Skorupski Yes in SIM Simulator. Only required for MPlane O-RUs
    • Pawel Slowikowski Is network required for this call home? Other protocols? Martin Skorupski Currently must be netconf according to O-RAN Alliance.
  • o-ran-fm:alarm-notify to ves:fault
    • Still in progress - for O-RU use case
    • Similar to above to translate netconf faults from O-RU into VES events

ONAP - OSC

Swaminathan Seetharaman cannot attend this meeting. Suggesting only attending every second week due to timing.

ONAP Topology Service/Model (ref last week)Andy Mayer

• Martin Skorupski See ticket in Jira to kick of the modelling activity in ONAP: https://jira.onap.org/browse/ONAPMODEL-35  ONAP internal topology model
• Andy MayerMartin Skorupski https://wiki.onap.org/display/DW/Abstract+Topology+Model & Discussed during Modelling Sub-Committee meeting.
• Lots of progress in coming months

O-Cloud question from Lasse Kaihlavirta

• Martin Skorupski to check if Lasse Kaihlavirta question was resolved
  • Lasse Kaihlavirta No response. Martin Skorupski will try again

Other

• Konrad Bańka Still looking for interesting topics to contribute in A1 Policy work in ONAP
  • John Keeney Many of our requirement already done for Honoloulu
  • If interested, we're examining how to add HTTPS proxy support for A1 Adapter (e.g. user-4594e Bastion in a real world deployment) but may have serious knock on effects for other functions & regression testing using SLI graphs etc ....
  • John Keeney Any other ideas, requirements or contributions are very welcome from the community

• Sowmya Narayanasetty
  • Questions re setup A1 Policy functions (ref last week & week before) ...
    • Still trying to view policies not showing up in control panel. & Struggling with configuration
    • John Keeney Please continue to engage over email. Most likely a configuration error. More verbose logging information and setup environment information would be useful See also tests in ONAP (CSIT) and OSC (nonrtric/tests) for more examples too.

• Vidhu Shekhar Pandey Any more detail on the O-DU to O-RU communications?
  • Martin Skorupski See further details in RSAC slidedeck (slide#51) : https://wiki.o-ran-sc.org/download/attachments/3604609/Dawn_rel_v4.12.pptx?api=v2
  • Martin Skorupski Still struggling with the requirement to have usecase specific models for this rather than 3Gpp or IETF models ... But remains v.tricky
  • Discussions continue in RSAC meetings.
