Use Case

@Swaminathan Seetharaman

Use Cases

Please see:  Potential ONAP <-> O-RAN collaboration use cases



AI: use case on O-RAN-SC towards ONAP

00:30

Closed loop

@John Keeney (Ericsson EST)

Use Case 

  •  

    • O-RAN-FH node (VES triggers O1 change)

      • VES-fault-event

      • you see it on DMaaP

      • fault to DMaaP

      • rApp (µService, app, ....??? ) via OAM config change (see POSTMAN scripts)


        • Next steps

          • define the message flow and involved projects/components

          • O-DU interface goes down - O-RU detects interface to O-DU is down and sends VES 

          • SMO should send message to O-DU to bring the interface back

  •  

    • O1 - Near-RT-RIC  (VES triggers A1 change)

      • VES-fault-event

      • you see it on DMaaP

      • Non-RT-RIC rApp reads from DMaaP

      • update A1 policy in Near-RT-RIC/xApp

00:50





Questions and Answers

  • wiki for yang-validation in OSC LAB - instructions @Alex Stancu- provide link 

END



Backup











@Mahesh

Application Package Structure

  • TOSCA 

Info from @Michela Bevilacqua

  • ONAP enhanced TOSCA 

  • API schema definition for YANG and VES

On the agenda for next week - thanks!!! 

@Zu Qiang presenting ONAP on-boarding package



--

CNF packaging and App packaging - seems there is some overlap?!?!?







Questions and Answers

  • data model - from Bitbucket DM with 3GPP and O-RAN (draft - November train)

  • closed loop use case with A1 and O1 

    • E2 sim functions may needed

APP package implementation

  • once the package spec is available - what would be the next steps?

Mahesh

Postman scripts to interface with the SMO and in turn test O1 interface between the SMO and different parts of O-RAN instances of O-CU, O-DU, O-RU and RIC using these models. 

  • yang modules

  • framework for test and validate CM 

share content in in SMO gerrit and create wiki linking to the same source

  • Working on a framework for vendors for OAM/YANG tests

  • O-RAN-SC to host the framework

  • Postman and vsCode as RestClients

  • Alex about to setup a SIM in OSC lab - involve Rittwik in a O-RAN private lab

  • OpenFronthaul

  • 3GPP models are considered.

Feedback from Rittwik

  • SMO in T-Labs

  • how to run Netopeer server - req to Felix (O-RAN-SC INT PTL)

  • Alex asked for VMs 

Init script (Postman) for O-RAN OAM FH M-Plane (o-ran-interface.yang augmenting ) interface demoed

RFC8040 (RestConf by IETF) support supported by ODL

@Konrad Bańka

Konrad is absent this week. The presentation will be made when Konrad is available.

O-RAN Component deployment

The question is: How to deploy the red colored CNFs/VNFs of the O-RAN-Architecture?

  • CNF for O-RAN-components 

    • model of CNF - how to be configured, how many components, blueprints

    • CDS model needs to be created

    • Network-service based on several CNFs

      • CNF types

        • Near-RT-RIC

        • O-CU-UP

        • O-CU-CP

        • O-DU

For detailed discussion the following page was created:



Package

  • for Network Functions (priority)

  • for Network Service (second step)

CNFs or VNFs

  • both should be considered 

    • let's start with CNFs first

    • VNF is considered as additional option



  • no CNFs and VNFs combined in a single package

    • maybe not for rApps → 

    • VNF should take care about internal CNFs
