| Interface Name | Definition | Capabilities | Version | Status | Payload Model(s) | API Spec (Swagger) |
|---|---|---|---|---|---|---|
| POE-1 | Policy Type Design | Allows applications to create, update, delete, and query PolicyType entities so that they become available for use in ONAP by applications such as CLAMP. | 1.0.0 | production | tosca.policies.root | https://docs.onap.org/projects/onap-policy-parent/en/latest/api/api.html#api-swagger |
| POE-2 | Policy Design | Allows applications (such as CLAMP and Integration) to create, update, delete, and query Policy entities. | 1.0.0 | production | tosca.policies.root | https://docs.onap.org/projects/onap-policy-parent/en/latest/api/api.html#api-swagger |

| POE-4 | Data Ingress | Listen on a DMaaP topic. | production | Messages of interest are described in the policy logic DMaaP | ||
| POE-5 | Decision Query | Policy 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. | NA | production | Defined by policy | https://docs.onap.org/projects/onap-policy-parent/en/latest/xacml/decision-api.html |

| AAF | Policy Framework | Authentication and authorization | |
| DMaaP | Policy Framework Policies | Policy framework uses DMaaP for SDC subscriptions and internal communication. Policies use DMaaP as a transport for contextual information from various sources | |

3. Component Description
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.
...
Policy Enforcement is in general not handled by the Policy Framework. Enforcement is handled by either the originator of a decision query (PDP-D does enforce guard policy decisions made in the XACML PDP), or by a reaction to a policy output (trigger).

The main new capability introduced in this release as a PoC is the integration of the CLAMP component under the policy umbrella (see

And additional PoC experiments with defining Control Loops fully in Tosca. This is covered by

As outlined in the architecture review page (Policy Honolulu-R8 Architecture Review) the only new use case that may be supported as a stretch goal is the 5G one (

Additional enhancements to the Policy components will be introduced in this release that have no external impact. These include but are not limited to:
- 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.
