Notes:

Housekeeping:

• Reminder from previous weeks:
  • OSC SMO calls now move to its own time slot - Thursdays
  • See OSC RSAC Calendar: https://lf-o-ran-sc.atlassian.net/wiki/display/RSAC/calendars
  • (Note this meeting to open to anyone, including non-ORAN members)
  • We will maintain this slot for ONAP Alignment, and try flag issues/question to/from SMO meetings.
  • See OSC SMO Project meeting notes
    
• O-RAN has declared that recording are kept for 2 weeks only. Does this apply to us? 
  • Is this a requirement, a privacy issue or a cost issue?
  • Not sure - the recording storage quota that we use is currently full - so we may need to delete old cloud recording?
  • All past recording are also available as files uploaded to the wiki pages - May be a  storage issue later, but no plans to delete as yet.

OSC Project roundup:

NONRTRIC (John Keeney (Ericsson EST))

• Working hard on integration & documentation tasks now that OSC M4 date has passed.
  
  • ReadTheDocs Documentation esp. is very out of date!
• ONAP A1 Policy Functions - need to wrap M1 tickets for ONAP I.
• John Keeney (Ericsson EST) Martin Skorupski Alex Stancu, Felix & Mahesh  - Hope we can catch up to figure out our way through the e2e integration tasks for OSC D release
  • Will discuss initially at RSAC call tomorrow (20 May)

SIM (Alex Stancu)

• Bug fix for VES for O-DU & O-RU simulators - new version available
  • VES File ready event
  • version 1.3.1 now
  • O-RU now send fault event ID 28 and fault 30 when connection to O-DU fails (2 events) (John Keeney (Ericsson EST) need to update Link Monitor App to ignore one of the faults)
  • See updates in SIM Wiki: "D" Release - Closed Loop Use Case: Simulation of O-RU and O-DU

OAM (Martin Skorupski)

• Working on docker compose for SMO test environments 
• Has several docker-compose files for different deployments etc

O-DU (Hariom Gupta)

• Commit ready for review/merge.

CM Notifications in ONAP

• Marcin Wilk: Is anyone in SDNR/CCSDK/OSC working on CM Notifications?
  • Martin Skorupski lots of work on VES - esp faults & netconf call home
  • Damien from DCAE project also in Guilin worked on newer functions in VES to support this & collction to DMaaP
    • Marcin has verified this worked
  • NK Shankar: Some work ongoing for this in the ONAP OOF SON use case (Calls Friday 9:?? EST for more info)
    • For OOF SON use case - CM notifications for CPS - part of CCSDK - used in SDNR
    • Events come from RANSIM simulator
    • Sandeep Shah Working on this.  JIRA: https://jira.onap.org/browse/CCSDK-3296
    • Still figuring out how exactly to do this with VES etc - but work is ongoing.

Helm charts / Docker Compose etc

• John Keeney (Ericsson EST) working on Docker-compose & helm charts for OSC D +
• Want to have BOTH docker-compose and helm charts for deploying functions. Martin Skorupski Good idea - means dev & release versions can evolve independently & lots of different configurations etc.
  
  • John Keeney (Ericsson EST) Will maintain both ... and each function in nonrtric have their own docker images - and are pretty standalone - so are easiy to deploy individually or in different combinations.
• John Keeney (Ericsson EST) Would like to maintain multiple flavours of helm charts for nonrtric in nonrtric repo, and then reuse in IT/DEP.
  • But we need to be very careful that we actually manage to have a test-environment integrated deployment at release times.
• John Keeney (Ericsson EST) Reminded the OSC TOC today that it was previously discussed adding PTLs as committer in the IT/DEP repo - to help Felix & avoid bottleneck. Will hopefully happen soon in coming days.

How do we refer to or position or differentiate between SDNC / SDNR / NONRTRIC / SMO etc

• Question by NK Shankar
  
  • John Keeney (Ericsson EST) We don't - it depends on your perspective.
  • OSC:   
    • OAM, NONRTRIC and SMO are all different projects in OSC only
      • OAM mostly reuses software from ONAP - main focus OAM & O1 - software comes from DMaaP, DCAE CCSDK/SDNR in ONAP.
      • NONRTRIC Has multiple functions (see Release D - DRAFT) - only A1 Policy functions are taken from ONAP CCSDK - all rest are developed in OSC.
        • Focus on functions for A1 Policies, A1 Enrichment, R1, RApps. Plus control panel & A1 Simulator
      • SMO project currently  develops new functions for OAM - not from ONAP
  • ONAP
    • There is no concept of SMO or NONRTRIC in ONAP - these are OSC concepts
    • Lots of functions in ONAP that can be useful for an SMO (especially in CCSDK for O1 & A1 Policies)
    • Ref also SON & Slicing use cases in ONAP that touch on ORAN related concepts.
  • It is hoped that functions can be mixed & matched as a need arises - and hopefully we can stay aligned & support resue - which is one of the main focus of this meeting series!
  • NK Shankar - looking forward to use cases & reusing concepts - not sure yet how/where work will be homed if in ONAP - Martin Skorupski Lets use this meeting series to get such discussions straight!
  • William DIEGO - Introduced - As an OSC TOC member will help liaise between OSC & ONAP - from OSC
  • Timo Perala Chaker Al-Hakim will help out from ONAP side (TBC as replacement for Swaminathan S)
