  • This is the Gerrit submission for the Postman script. https://gerrit.o-ran-sc.org/r/c/smo/o1/+/4998
• Non-RT-RIC:
  • focus - R3 (Cherry) - code freeze - documentation in ONAP ongoing ...
  • http proxy and rest config the function 
    • Non-RT-RIC - bundle function into the same controller as OAM as deployment option
  • ONAP pull to O-RAN-SC (code is hosted in ONAP)
  • Deployment based on OOM
  • policy enrichment functions

      • VES file ready from O1-Sim
      • FTPes to O1-Sim
      • PM-mapper
      • using a REST client for VES-PM on DMaaP
    • Basic Config
      • alarm-list
      • inventory
      • visualization and modification of O-RAN-FH parameters

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

Use Case 

• • O-RAN-FH node (VES triggers O1 change)
    • VES-fault-event
    • you see it on DMaaP
    • fault to DMaaP
    • SMO app via OAM config change (see POSTMAN scripts)
  • 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

APP package implementation

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

Backup

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 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:

• CNF deployment of O-RAN Components 

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
