CPS Data Notifications

CM VES Message

https://www.rfc-editor.org/rfc/rfc8641

O1 CM Update Notification VES Message

DMi Data AVC Sample Message

SON Use Case Weekly Meeting Notes

Assumptions

#

Issue

Notes

Decisions

1

VES Event is received via Strimzi/DMaap Kafka on DMI.

Yes. This is agreed.

2

Changes in CM data will result in CPS-Core sending a CPS Data AVC irrespective the origin of the change.

See #4 in the Bigger Picture below.
This could later be model controlled to be more granular.

Agreed.

Issues & Decisions

#

Issue

Notes

Decisions

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.

VES format primary reference is here: [INT-2180] Define CM VES message aligned with 3GPP/O-RAN O1 - ONAP JIRA

2

Topic from where we will receive the CM VES Message.

Existing channel or channel owned by NCMP/DMI

Vishal Varvate to provide the topic details.

Priyank Maheshwari ,please use below topic

unauthenticated.SEC_3GPP_PROVISIONING_OUTPUT

3

How do we retreive

Mapping of the relevant information from the CM VES Message

CmHandle
Xpath
Operation that happened

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

moiChanges.operation
moiChanges.value
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?

The fields which are of importance are :

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

Sample CM VES event having href and path attribute.

{

Mapping detailed below: VESEvent%E2%86%92DMIDataAVCMapping

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.

Image Removed

Yes. CMNotify and CM VES message are the same.

Analysis

Dataspace : NFP-Operational , Schema-Set : cps-ran-schema-model , Anchor : ran-network-simulation
Yang Resource : cps- ran-schema-model ( tree form : network to be used. ( trimmed down version just like 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.
