Housekeeping:
- Reminder from previous weeks:
- OSC SMO calls now move to its own time slot - Thursdays
- See OSC RSAC Calendar: https://wiki.o-ran-sc.org/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)
- Continuing work as reported in past weeks - working toward OSC D code freeze
- We are testing a first version of a script for the O-RU recovery use case - Script version and ONAP-Policy version
- Finishing touches to Control Panel upgrade activities
- Integration tasks will likely run over into the Integration sprints. - e.g. deployment scripts, tests, etc.
SIM (Alex Stancu)
- New version of O-DU and O-RU simulators
- See updates in SIM Wiki: "D" Release - Closed Loop Use Case: Simulation of O-RU and O-DU
OAM (Martin Skorupski)
- Working mainly on integration for the O-RU use case & test cases
- See OAM Wiki: D-Release Integration
- D-Release Integration - Test Environment
- D-Release Integration - O-RU on-boarding
- D-Release Integration - O-DU on-boarding
- D-Release Integration - O-RU closed loop
- - OAM-190Getting issue details... STATUS
- Lots of tests cases - most pass already.
- See OAM Wiki: D-Release Integration
- Working with Lasse Kaihlavirtatesting/verifying pnfRegistration event for O-DUs
- Still testing - may need more help from Martin Skorupski - will discuss over slack
- HariomGupta(HCL) Need some help re pnfRegistration VES event producer from O-DU - Re O-DU port changes. Please check the gerrit review.
- Needs some examples - will share via Gerrit? & Any other logs needed
LFN ONAP Honolulu Webinar
- Presentation from Catherine LeFevre, John Keeney, Swaminathan Seetharaman
- https://www.lfnetworking.org/event/lfn-webinar-onap-honolulu-is-here/
- https://www.youtube.com/watch?v=d4X4VrBKDgs
- Positive message about ONAP maturity and helping towards achieving the O-RAN Vision
- Lots of interest about the slicing activity (not just at the seminar - but in the community + industry in general )
Topology Modelling
- Andy Mayer - Confident work on topology modelling will be a big help for slicing. Can including slicing concepts in Topolgy model
- https://wiki.onap.org/display/DW/Abstract+Topology+Model
- Karthik (?) working with Andy Mayer around TAPI topology model
- Alex Stancu working on a service to expose TAPI models for topology modelling - Research activity - can hopefully make available in opensource & maybe input for O1?
- Andy Mayer MEF are already looking at this - based on TAPI (part of Presto API) - especially for Ethernet etc - could be extended into a general topology model? Could/Should coordinate ONAP/O-RAN & MEF?
- Alex Stancu Wondering if anyone knows if TAPI will move to Yang 1.1 (currently 1.0)? - Should ask Karthik? - Could ask at ONF/TAPI call on Tuesday or ONAP modelling call on Friday?
- Discussion about implementing a Topology Service:
- Is it an O1 and A1 activity? : John Keeney O1 is most useful for RAN topology
- John Keeney Most important to have a solid model first before implementing. Service that the SMO should provide.
- Also need to consider core, transport topology too - so not just O-RAN.
- Andy Mayer Needs to be use case driven
- Proposed model sketch: https://wiki.onap.org/display/DW/Proposed+Topology+IM+Sketch - but needs to be used/populated to verify.
- NK Shankar: Is TAPI the best place to start? Maybe should start with something simple - e.g for the SON use case - cells, neighbors, etc is very different from actual connections (logical vs physical views)
- Likely need simplified logical views .
- Andy Mayer Best to sketch out some use cases - will verify model & drive requirements.
- John Keeney Probably need a well-thought out base/canonical model to act a base for other logical view.
- Source of truth is config data (O1) and Inventory.
- NK Shankar - This is very hard to achieve - simpler logical views is easier to achieve & work with John Keeney Needs to be grounded in reality though
- John Keeney For example for NON-RT-RIC use cases we need live topology information about UEs - which makes the topology service very difficult!
- NK Shankar - lots of layers/views - probably can't implement the whole thing from scratch - need to make simplifications.
- Needs further discussion at ONAP Modelling subcommittee meeting https://wiki.onap.org/display/DW/Modeling+sub-committee+meetings
O-RAN F2F - 01-14 June 2021
- No update
ONAP Q/A
- Vidhu Shekhar Pandey - Needs access to O-RAN SC lab lab to try O-DU for integration tests to test/demo O-DU. O-DU runs in a VM directly - not a Docker image so a but difficult to do without lab access.
- Martin Skorupski Can try help get access to VMs to test.
- Vidhu Shekhar Pandey to Martin Skorupski Please check out the Gerrit review for the VES event producer etc.
Follow up note:
- Swaminathan Seetharaman - who had to leave the meeting midway - informed us all recently that he is changing roles
- We are sorry to see him go. Thanks for helping alot with this meeting series over the past few months.
