1. Project Overview

DCAE platform includes components collectively fulfilling the role of Data Collection, Analytics, and Events generation for ONAP. The architecture of DCAE targets flexible, pluggable, micros-service oriented, model based component deployment and service composition.

DCAE also support multi-site collection and analytics operations which are essential for large ONAP deployments. DCAE components generally fall into two categories: DCAE Platform Components and DCAE Services Components.

DCAE Platform refers the set of controller components which manages the deployment and LCM of the DCAE service components which include all the collectors, analytics and event processor MS. 

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

Following new components introduced for Dublin

Event Processors

  •   DL Handlers integration (DL-Admin, DL-Feeder)

Analytics/RCA

  •   PM-Subscription Handler 
  •   TCA-Gen2 (STRETCH GOAL)

Platform Enhancements

  • DCAE MOD (mod/genprocessor, mod/runtimeapi, mod/distributorapi, mod/onboardingapi , mod/webui - NiFI)
  • Acumos-ONAP DCAE adapter (POC)
  • OTI (Phase1) - EventProcessor, Event-Handler

3. New or modified interfaces

Architecture diagram - DCAE R6 M1 Release Planning#Highlevelarchitecturediagram

New External interfaces

  • MOD (Onboarding API to AcumosAdapter)
  • Policy Handler (via DMaaP)
  • PM-Subscription Handler (via DMaaP)
  • TCA-gen2 (via DMaaP)

Modified interfaces

  • VES Collector (security)
  • InventoryAPI (MOD Flow support for CLAMP)

If they are modified, are the backwards compatible?

  • VESCollector - Yes
  • InventoryAPI - 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.
Cloudify is 3rd party product; multi-site feature on community version will be available later in 2019; will be incorporated for E release.


7. Involved use cases, architectural capabilities or functional requirements

  • Usecases
    • Self Serve Control Loops v2
    • Policy Update Notifications
    • 5G / OOF SON Enhancement
    • 5G / Bulk PM / PM Control
    • 5G / Bulk PM / Secure Communication between xNFs and ONAP
    • PNF / Plug and Play
