1. 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.

2. New component capabilities for Jakarta, i.e. the functional enhancements

...

• Reducing DCAE backlogs  + security fixes

3. New or modified interfaces

New External interfaces

• • None

Modified interfaces

• • PMSH - Adds new API support for Subscription/Filters/Measurement group management (this will be consumed by Policy)
  • Slice Analysis -  API to provide 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

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)
