OSC SMO Meeting Series: 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

NOTE: DST Changeover in coming weeks!

• Keep a close eye on the calendars!

OSC Project roundup:

News from OSC TOC call this week

• https://lf-o-ran-sc.atlassian.net/wiki/display/TOC/

• We all remain totally confused about copyright..... will update when we know more

• Integration project PTL election ongoing

NONRTRIC (@John Keeney (Ericsson EST))

• Work examining ONAP Control Loops as a basis for rApps in OSC ... looking promising

  • Still have alot of work to do, e.g. packaging & distribution, but working away

• ONAP A1 Policy Management: Istanbul JIRA tickets to be closed before release date!

• Short introductory-level presentation at ONES 2021

SIM (@Alex Stancu)

• Addressing in SMO deployment (see below) (Use hostname, not ip:port)

OAM (@Martin Skorupski)

• Working on a basis for an O-RAN topology model

  • Could be reused in O-RU use case.

  • @N.K. Shankaranarayanan Does O-RAN Topology include O-RU?

  • Ref discussions on ONAP Topology modelling, including @Andrew J Mayer

  • @N.K. Shankaranarayanan Ref discussions in O-RAN WG1 (Cagatay - AT&T)

  • Not including Core Network.

  • Issues:

    • No agreed model, and even if there was it would not suit most peoples' requirements - everyone wants different topology models for their requirments.

    • Very hard to keep any complete topology model populated & synchronized

    • Too many layers to have a complete model ... and layering is not necessary accurate.

    • Must be model-driven.

      • A model that cannot be populated is useless!

O-DU (@Hariom Gupta (Deactivated))

• @Hariom GuptaStill figuring out if 3GPP Yang model can be used. 

• JIRAs created for cells & VES measurement events

OPS-5G (@David McBride, Doug Evans)

• See discussions 2 weeks ago

• Introductions:

  • Andy Leidy, Arnold Alvarado, Douglass Evans (USN), Louis Raspberry, Neil Hoff, Ryan McAllister

• Note session at ONES summit

  • Martial: Will the recordings/slides be available? (Think recordings appear on youtube in a few weeks)

  • Doug: Spotted interesting presentation re Acumos alignment (ONAP & OSC)

    • Ref work in DCAE-MOD for reusing Acumos models & work in Acumos to package models as xApps.

ONAP SMO deployment options

• Sebastien: Working on

  • Pull Request on OSC it/dep repo for existing SMO Deployment package

  • Readme

  • Scripts

  • Testing

  • Trying to reduce footprint

  • Testing O-RU/O-DU/Topology-Server deployment

  • VES Collector configuration with SDNC

• Pull request coming soon (this week?) for wider review & comments.

• @John Keeney (Ericsson EST) & @Xue Gao working together on A1 deployment ... perhaps use existing test suite to avoid having to do new tests? 

• @John Keeney (Ericsson EST) We are working on modularizing NONRTRIC helm charts, which may affect work here ... ...

  • Will also look carefully at the current versions in SMO deployment ... Lots of progress already made!

    • Plan to evolve when modular helm charts are available

Q&A

• Copyright & Licensing

  • SCCL: Any open source project can reuse SCCL artifacts - if they abide by by process for that license

    • Note SCCL is not an opensource license!

    • ONAP may want examine/reuse? the work in OSC for supporting SCCL?

  • Long discussion about 3GPP licensing:

    • Open/Public != OpenSource != Free

    • Try to keep functions model-driven as a much as possible so loosely coupled from copyrighted specs/model, so specs are not reproduced/re-distributed.

      • But this is not possible for the actual function encoding the model (e.g. a netconf server & Yang model) or function simulators/emulators, or POCs

    • We see no clear path forward for this very long running issue.

      • We need to be conservative until we have clear guidance / path forward.

      • Unwilling to risk copyright or IPR infringement

      • Likely a common-sense reuse approach is possible - with no commercial aspect involved - but we cannot assume this.
