Description

Use Case Title

ONAP/3GPP & O-RAN Alignment-Standards Defined Notifications over VES

Actors (and System Components)DC

DCAE VES Event Listener, DCAE-SDK, SchemaBroker, xNF

Description

Short overview of the Use Case

Points of Contact

This contribution introduces a new domain in VES, stndDefined, which indicates that the event contains data that conforms to format/schema defined by a separate standards organization.  In addition we propose one new field in the VES Common Header to enable further classification of such events, e g to support routing of these events to appropriate DMaaP topics.  An optional second stage validation is proposed in DCAE prior to acknowledging the event to enhance trouble shooting.

Preconditions

Preconditions for a system (xNF & ONAP) before a xNF sends a stndDefined VES event:

the xNF has been onboarded (artifacts in the onboarding package describe the VES events that the xNF supports).

xNF has gone through registration with ONAP. e.g. in the case of a PNF, it has gone through Plug and Play and sent pnfRegistration event.

ONAP system that supports VES 7.2 or later.

Preconditions

A list of conditions that are assumed to be true before the Use Case is invoked

Includes description of Information Consumed

Triggers / Begins when

xNF emits a VES notification that contains data which follows the schema defined by a standards body with a VES Common Header where the domain field is populated with the stdDefined stndDefined value which is destined for the DCAE Collector.
