- Documentation refresh needed
- Providing update to O-RAN Alliance WG2 tomorrow (Thursday 21 Jan)
- ( Links added after the meeting: WG 2 Meeting notes, Slides: OSC-2021.01.21-WG2-I-OSC-NONRTRIC-ShortStatus-JohnKeeney-v01.pdf)
- Still working through the OSC O-RU usecase ... see below.

ONAP - OSC
OSC Proposed e2e integration use case: O-RU FH connection recovery
- REF/Background:
- (OAM) Closed loop use case
- (RSAC) Meeting 14 Jan:
- Martin Skorupski provided intro
- Alarm when fronthaul connection dies (O-DU - O-RU) (VES to SMO)
- John Keeney If there is a failure both O-DU & O-RU will try reconnect anyway - without this loop? Martin Skorupski Yes.
- @? How does SMO connect to O-RU?
- Martin Skorupski This is a mix of different deployment options (hierarchical vs hybrid, O1 vs M-Plane). Main issue is agreeing models & terminology.
- John Keeney Seems this use case is not real-world useful, especially since recovery will happen automatically anyway, & mix of standards ...
- Martin Skorupski John Keeney Using this use case as longer term motivator for SMO/NONRTRIC/rApp development - independent of usecase
- Topology ??:
- May need a topology service for this use case - John Keeney Will use a simple file/hardcoded for initial versions of this use case.
- Pawel Slowikowski Andy Mayer Topology in A&AI, CPS ? John Keeney No - not initially. Plan to keep it simple for this release.
<bridge dropped recording stopped at this point. Most participants reconnected once bridge started again>
- Topology ??: (contd)
- John Keeney Lots of options for how this should be done properly in ONAP.
- Swaminathan Seetharaman ONAP usecases already have some plans for this e.g. slicing, oof, etc
- Andy Mayer A model should be agreed in ONAP. Lots of previous discussions in ONAP - e.g. what goes in A&AI and CPS ... but that was a while ago.
- Martin Skorupski SDNR has some topology model too - not standards based.
- @Sven John Keeney Martin Skorupski Lots of issues with different topology models ... and most existing hierarchical models break down in a 5G/CloudRan environment
- Lots of work ... Andy Mayer Martin Skorupski Can create a JIRA in ONAP MODCOM ...
- ... but will keep it simple here for this use case.
- @? Will other O1 usecases be effected? Martin Skorupski No. O1 functions continue as before.
- Martin Skorupski Please add feedback if any
ONAP Usecases Update
- Swaminathan Seetharaman could not attend.
