Summary

Goal:

View topology based on a CM data export

Components:

OAM - Operation and Maintenance. According to the O-RAN OAM Architecture and the O-RAN OAM Interface Specification, the SMO implements a NETCONF Client for configuration and a HTTP/REST/VES server for receiving all kind of events in VES format.

DU and RU APPs interacts with OAM on the O1 interface for configuration, alarms and performance management.

SDNC - Software Defined Network Controller. A global network controller which manages, assigns and provisions network resources.

Open Questions

	Question	Notes	Decision

	Question	Notes	Decision
1	What to look for in the VES Event?	event.commonEventHeader.sourceName ?? to get the node name ?	Yes
2	What is the schema for the VES Event?	John will let me know.
3	How to ignore other events?
4	What is the topic ?	unauthenticated.VES_PNFREG_OUTPUT ?? Note : I see event for only one device on this topic.	unauthenticated.VES_O1_NOTIFY_PNF_REGISTRATION_OUTPUT and unauthenticated.VES_PNFREG_OUTPUT
5	Which datastore to be used in NCMP ?	passthrough-running → content=config passthrough-operational → content=all
6	Do we need to use the options , include-descendants field in NCMP. and what does it correspond to in the SDNC side?
7	Any specific model to be used for the demo ?	for now we onboarded a simple bookstore model. But can build examples around that if any specific model needs to be used.
8	Are there any events which can show the change in configuration in SDNC and can be listened back by NCMP to keep the cached data upto date.

Issues/Decisions

	Issue	Notes	Decision

	Issue	Notes	Decision
1	Onboard bookstores yang model.		@Priyank Maheshwari Able to onboard.
2	Register the device using the discovery process in NCMP.		@Priyank Maheshwari Done
3	Read the data from the device.	from parent node or child node or both ?	@Priyank Maheshwari Able to read from root and with filters as well.
4	Write the data to the device.	from parent node or child node or both ?	@Priyank Maheshwari Able to create and update.
5	Data sync for pynts-o-du-o1 device.		Cause : Root data endpoint for pynts-o-du-o1 is not working as expected.
6	Data validation during passthrough operations		@Priyank Maheshwari CPS-NCMP do not validates the data for passthrough operations. But if we use the CPS cache then the validation is done. ( If we use the datasync flag )

	Use Case / Flow	Status	Comments
1	ONAP DMI Plugin connecting with SDNC		Verified using Manual Device Registration from ONAP-DMI-PLUGIN.
2	ONAP DMI Plugin listening to VES event for device registration	this is to automate the device registration.
3	Data Synchronization at NCMP side	Partially Failing ( works for 1 out of 2 devices ) in scope ??
4	Reading data from devices using CPS-NCMP	?
5	Writing data to devices using CPS-NCMP	?
