1. Project 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.
...
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 Honolulu, i.e. the functional enhancements
DCAE Focus for R7
- Address ONAP R7 Usecase & Functional requirement
- Address TSC/SECCOM MUST-HAVE non-functional requirements
- General platform optimization
- DCAE Bootstrap/CM Manager optimization
- MOD catalog/UI redesign (POC)
- Addressing DCAE back logs + security fixes
...
For Honolulu, new MOD Front-End and Back-end components is being worked as PoC tracked under REQ-326 -Self Serve Control Loops (this would eventually replace NiFI based UI/processor in subsequent ONAP release)
3. New or modified interfaces
Architecture diagram - DCAE R8 M2 Release Planning#Highlevelarchitecturediagram
New External interfaces
- Data Extraction Service API - Provides basic computation and data retrieval/access from datastorage maintained by DL handlers (Feeder). This API will be consumed by Slice Analysis MS (DCAE) and UUI
Modified interfaces
- VES Collector (7.2 VES support)
If they are modified, are the backwards compatible?
- VESCollector - Yes

6. What are the system limits
Relies on k8s for loadbalancing and scaling. DCAE platform handles the control flow and do not carry the data/event; DCAE service components can be scaled and support state management through external DB and/or K8S state management.
Cloudify is 3rd party product; multi-site feature on community version will be available later in 2020; will be incorporated for G release.
