) .     CLAMP's functional role to provision Policy has been enhanced to support provisioning of policies outside of the context of a Control Loop and therefore act as a Policy UI. In Istanbul release the CLAMP integration will be officially released

POE-5Decision QueryPolicy decisions are required by ONAP components to support the policy-driven ONAP architecture. Policy Decisions are implemented using the XACML and Apex PDPs. The calling application (which may be another policy – e.g. invocation of a guard policy from PDP-D) must provide attributes in order for the PDP to return a correct decision.NAproductionDefined by policyhttps://docs.onap.org/projects/onap-policy-parent/en/latest/xacml/decision-api.html

Policy framework uses DMaaP for SDC subscriptions and internal communication.

Policies use DMaaP as a transport for contextual information from various sources

The ONAP Policy Framework is a comprehensive policy design, deployment, and execution environment. The Policy Framework is the decision making component in an ONAP system. It allows you to specify, deploy, and execute the governance of the features and functions in your ONAP system, be they closed loop, orchestration, or more traditional open loop use case implementations. The Policy Framework is the component that is the source of truth for all policy decisions

Please see the TOSCA Policy Primer page for an introduction to TOSCA policy concepts. See the Policy Design and API flow page for a description of the component interactions.

...

  • Stateless PAP (Keep no state in PAP runtime container, so state retrieval would be from database).
  • Interoperability of Native and non-native policies in the Drools PDP. 
  • Healthcheck status improvements as well as statistics reporting.
