Preconditions | A list of conditions that are assumed to be true before the Use Case is invoked Includes description of Information ConsumedThis 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. |
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. |
Steps / Flows (success) | Describes the sequence of steps and interactions that occur during the Use Case (may include: description, data exchanges, functionality, state changes) Interaction diagrams may be included or referenced |
