OSC Project roundup
NONRTRIC (@John Keeney (Ericsson EST))
Maintenance release: (OSC)
Still assembling the update
Updating the version of A1-Policy functions pulled from ONAP (close to Mater (22-Jan))
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.
SMO (@Mahesh Jethanandani )
No update - need to confirm with @Mahesh Jethanandani if this time is suitable.
SIM (@Alex Stancu)
Defining new epics for Dawn - mainly keeping up to date with new spec versions
Hoping to add a new use case simulator - from Facebook - more details to follow at f2f (from TIP project?)
Still onboarding Viaivi simulator - ongoing
OAM (@Martin Skorupski)
Working on Epics for Dawn
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 (Ericsson EST) 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 (Ericsson EST) Seems this use case is not real-world useful, especially since recovery will happen automatically anyway, & mix of standards ...
@Martin Skorupski @John Keeney (Ericsson EST) 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 (Ericsson EST) Will use a simple file/hardcoded for initial versions of this use case.
@Pawel Slowikowski @Andrew Mayer Topology in A&AI, CPS ? @John Keeney (Ericsson EST) 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 (Ericsson EST) Lots of options for how this should be done properly in ONAP.
@Swaminathan S ONAP usecases already have some plans for this e.g. slicing, oof, etc
@Andrew 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 (Ericsson EST) @Martin Skorupski Lots of issues with different topology models ... and most existing hierarchical models break down in a 5G/CloudRan environment
Lots of work ... @Andrew 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
