Overview

DCAE project provides intelligence for ONAP to support automation (via open-loop and CL) by performing network data collections, analytics & correlation and trigger actionable rootcause events.

...

With Jakarta release, DCAE Platform component centered around Cloudify will be deprecated. All Microservice orchestration and lifecycle management will be handled through Helm/Kubernetes. 

The DCAE services components includes all the microservices - collectors, analytics and event processor which supports active data-flows and processing as required by ONAP usecases. The architecture of DCAE targets flexible, micros-service oriented, model based component design and deployment. DCAE also offers support for multi-site collection and analytics operations which are essential for large ONAP deployments

3. New or modified interfaces

New External interfaces

• • None

Modified interfaces

• • PMSH -
Adds 
• • Adds new API support for Subscription/Filters/Measurement group management
;
• • (this will be
invoked by CLAMP. https://gerrit.onap.org/r/c/dcaegen2/+/121898
• • consumed by Policy)
  • Slice Analysis -  API to provide
details of remaining capacity available for queried slice
• • resource availability for existing slice/subslice. OOF is consumer of the API and will use this data to determine reusability of slice. -
 
• • NSI/NSSI Selection based on resource occupancy levels

Modified interfaces

• • ; SliceAnalysis will also subscribe to AAI notification to support User-intent triggered CL flow for Bandwidth assessment

Deprecated interfaces

• • Cloudify API (used for LCM of DCAE MS)
  • InventoryAPI (used for saving/retreving DCAE blueprints)
  • DeploymentHandler API (used by CLAMP for triggering MS deployment)
