Project Description: 

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.

DCAE components are classified between platform and service components.  DCAE Platform refers to the set of controller components which manages deployment and LCM of DCAE service components. 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.

Integation Support

DCAE team has been improving upon current CSIT and automated test via gating. In Frankfurt, DCAE team worked with Integration to setup several usecase test part of "Smoke Usecases" executed under gating job. Following service/usecase flow are incorporated in the gating


Companies that run ONAP DCAE

To our knowledge, the following companies have used ONAP DCAE components : AT&T, Bell Canada, Nokia, Ericsson, Wipro, China Mobile. As VES is approved standard for xNF integration for ONAP, many of DCAE collector/services are actively used for data collection/processing. 

DCAE Platform is running in production within AT&T since 2017. 


Other Information:

Being one of largest ONAP project (40+ active containers, 30+ repository), DCAE strives to adhere to ONAP code quality by improving its codebase with each release.  Many companies have already contributed to DCAE, showing the interest of the community for the project. DCAE components is also a starting point to discuss standards and implement representations of xNFs. 

VES standardization which is now recently adopted by 3GPP was successful through active contribution/support from DCAE team. VES is also used a internal event standard for all communications with analytics/correlation MS to simplify integration of new services.

DCAE plays vital role in control Loop execution in ONAP. DCAE team has been working on CL committee with CLAMP and Policy team to simplify control loop design and execution in ONAP.
