CM VES Message

Assumptions


#IssueNotesDecisions

Yes. This is agreed.
2Changes in CM data will result in CPS-Core sending a CPS Data AVC irrespective the origin of the change.
  1. See #4 in the Bigger Picture below.
  2. This could later be model controlled to be more granular.


Agreed.

1

CM VES Message format schema.

Who will own it ?

In order to process the message DMI plugin / NCMP should be aware of the schema of the incoming message it is going to be consume.
2Topic from where we will receive the CM VES Message.Existing channel or channel owned by NCMP/DMIVishal to confirm on the same.

How do we retreive the relevant information from the CM VES Message

  • CmHandle
  • Xpath
  • Operation that happened

Only fields that seem to suggest to have these info. are.

  1. moiChanges.operation
  2. moiChanges.value

  3. moiChanges.path ?? 

Related work in ONAP suggests this possible alternative schema:

https://wiki.o-ran-sc.org/display/SIM/Network+Slicing+Use+Case#NetworkSlicingUseCase-ExampleVESPMstndDefined

So wanted to confirm if measurements.measurement-type-instance-reference is xpath?

Need to confirm with the stakeholders

The fields which are of importance are :

  1. event.sourceId  ( we can extract cmHandle details from the sourceId )
  2. moiChanges.operation
  3. moiChanges.path
  4. moiChanges.value

More information is present in the meetings recording.

- Is CMNotify Message same as CM VES Message and notify more about this if this is relevant.


Yes. CMNotify and CM VES message are the same.

...

  • Dataspace : NFP-Operational , Schema-Set : cps-ran-schema-model , Anchor : ran-network-simulation
  • Yang Resource : cps-ran-schema-model ( tree form : cps-ran-schema-model_tree.txt ) existing ran-schema will be used.
  • We need to have a defined channel/topic where the VES messages are present , and NCMP should be able to listen , interpret/process and call the relevant CPS-Core APIs in order to publish the changes in the CPS DB.
