O-RAN SC: Copying/Releasing helm charts in O-RAN-SC nexus repo

https://jira.linuxfoundation.org/plugins/servlet/theme/portal/2/IT-22586 (maybe restricted access?!?!)

Status: canceled (Nexus does not support Helm chart distribution)

Question from O-RAN-SC to ONAP: What is possible in ONAP nexus?

Sébastien Determe: adds some info

Idea: store the artifacts - instead of helm -  RELENG-3837 - Getting issue details... STATUS

Christophe Closset: ONAP on the way to move for helm charts to gitlab....

00:20O1-VES

INFO: PM Streaming: ASN.1 via WebSocket according to O-RAN SpecO-RAN Operations and Maintenance Interface 4.0 - November 2020

Martin SkorupskiCheck with O-RAN Wg10 where the restriction to ASN.1 came from. 


Topic was discussed in DCAE Meeting: 2021-08-04 DCAE Meeting Notes


HV-VES vs "standard" VES collector

info: HV-VES not used by OOF-SON use case (yet)

info: no relation between HV-VES and PM-Mapper

2021-08-11 Krystian Kedron

I refactored current Jira’s base on our discussion:

And also create a new one:


VES - CM-Notify

The following 3GPP CM notifications specified in 3GPP TS 28.532 [4] are supported in O-RAN:

notifyMOIAttributeValueChanges

notifyMOICreation

notifyMOIDeletion

notifyMOIChanges


Its syntax is defined in

Shankar: point to a 3gpp....zip (https://www.3gpp.org/ftp/Specs/archive/28_series/28.532/28532-g81.zip → v16.8.1)

Marcin has looked into it. 

  • to complete and validate the entire json - additional yamls are required.
  • there are reference inside to other schemas - needs to be analyses - for validation on the ves-collector.
    • more infos next week


OOF-SON use case roadmap from last June.

Marcin was referring to slide 16 in this June 2021 LFN slide deck for the ONAP-SON use case. https://wiki.lfnetworking.org/download/attachments/56066778/LFN_June2021_ONAP_SON_Rel9_20210610_v1.pptx?version=1&modificationDate=1623339917000&api=v2

  • VES message handling on SDN-R 
    • used to update CPS
    • code is in ccsdk/features - northbound (CM Notification Support in ONAP)
    • DCAE VES Collector - implementation for VES 7.2 in Honolulu  
    • TODO: add link to nexus dcae-ves-collector–image.... (???1.8.0???)
    • gerrit repo: gerrit.onap.org:29418/dcaegen2/collectors/ves




00:40SMO deployment options

SMO deployment options

  • no tested helm for OAM in O-RAN-SC D-Release - idea update the one from C-release
  • for Non-RT-RIC a new helm is available - still some updates to be done
  • Please see presentation within  REQ-887 - Getting issue details... STATUS

Meeting? on Friday 6/25

https://lists.onap.org/g/onap-meetings/viewevent?repeatid=37969&eventid=1192141&calstart=2021-06-25


Activity

  • kubernetes updates
  • issues with certs addressed
  • reuse of O-RAN-SC helm 
  • Winriver lab

INFO from Christophe - 2021-06-30:

Just a few notes:

  • We have agreed with ONAP and other members of O-RAN SC to keep an ad-hoc call on Friday to discuss technical details for now (will remove this meeting once all details are sorted out and use the joint meeting to report status)
  • Main comment from John is that we cannot consider an SMO deployment without having a way to deploy Non-RT-RIC as well as ONAP components (hence a debate on how this should materialize : extend OOM? )
  • We have progressed on the POC in the meanwhile, Sebastien had an idea and has pushed a small repository on github to show what we are doing for now to create a unique installation for O-RAN, trying to implement the following idea:
    • Started from IT/DEP repo, containing some Helm charts for O-RAN (including Non-RT-RIC)
    • Seems an embryo of using ONAP charts to deploy SMO components but sounded like a fork of ONAP charts
    • Instead of copy pasting OOM charts, he create a git submodule referring to oom ONAP charts repo (to keep ONAP untouched)
    • Rework the O-RAN charts to map them to the OOM structure (like OOM'ized O-RAN charts)
    • Try and build (created some makefiles, inspired from ONAP) then push them to a single chart repository
    • Merged ONAP override and O-RAN override to have a single file
    • Created an Install script to deploy the charts in a single Namespace
    • … it worked more or less

We plan to show that maybe on Friday call (https://wiki.onap.org/pages/viewpage.action?pageId=103422272)

Q/A



N.K. Shankaranarayanan

SON use case

  • based on O1
  • How to include A1 in the SON use case? for the Network Slicing Use Case
  • Will be discussed on Use case Realization call (on Mondays)
  • use case in O-RAN-SC regarding Network Slicing - similar but not in all details

00:00Use Case

@all

OSC Proposed e2e integration use case: O-RU FH connection recovery

<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 i No. O1 functions continue as before.
  • Martin Skorupski Please add feedback if any
