This page shows how the Policy Design and API Flow to/from the PAP and PDP's will work to support Model Driven Control Loops in Dublin.
The figure below shows the Artifacts (Blue) in the ONAP Policy Framework, the Activities (Yellow) that manipulate them, and important components (Pink) that interact with them.

Please see the TOSCA Policy Primer page for an introduction to TOSCA policy concepts.
TOSCA defines a PolicyType, the definition of a type of policy that can be applied to a service. It also defines a Policy, the definition of an instance of a policy. In the Policy Framework, we must handle and manage these TOSCA definitions and tie them to real implementations of policies that can run on PDPs.
The diagram above outlines how this is achieved. Each TOSCA PolicyType must have a corresponding PolicyTypeImpl in the Policy Framework. The TOSCA PolicyType definition is used to create a TOSCA Policy definition, either directly by the Policy Framework, by CLAMP, or by some other system. Once the Policy artifact exists, it can be used together with the PolicyTypeImpl artifact to create a PolicyImpl artifact. A PolicyImpl artifact is an executable policy implementation that can run on a PDP.
The TOSCA PolicyType artifact defines the external characteristics of the policy; defining its properties, the types of entities it acts on, and its triggers. A PolicyTypeImpl artifact is an XACML, Drools, or APEX implementation of that policy definition. PolicyType and PolicyTypeImpl artifacts may be preloaded, may be loaded manually, or may be created using the Lifecycle API. Alternatively, PolicyType definitions may be loaded over the Lifecycle API for preloaded PolicyTypeImpl artifacts.
The TOSCA Policy artifact is used internally by the Policy Framework, or is input by CLAMP or other systems. This artifact specifies the values of the properties for the policy and specifies the specific entities the policy acts on. Policy Design uses the TOSCA Policy artifact and the PolicyTypeImpl artifact to create an executable PolicyImpl artifact.
Policy Type Design manages TOSCA PolicyType artifacts and their PolicyTypeImpl implementations.
TOSCA PolicyType may ultimately be defined by the modeling team but for now are defined by the Policy Framework project. Various editors and GUIs are available for creating PolicyTypeImpl implementations. However, systematic integration of PolicyTypeImpl implementation is outside the scope of the ONAP Dublin release.
The PolicyType definitions and implementations listed below are preloaded and are always available for use in the Policy Framework.

This policy type is used to support actor/action operational policies for control loops. There are two types of implementations for this policy type
- Existing Drools implementations that supports runtime Control Loop actions taken on components such as SO/APPC/VFC/SDNC/SDNR
- New implementations using APEX to support Control Loops.

This policy type is the the type definition for Control Loop guard policies for frequency limiting, blacklisting and min/max guards to help protect runtime Control Loop Actions from doing harm to the network. This policy type is developed using the XACML PDP to support question/answer Policy Decisions during runtime for the Drools and APEX onap.controlloop.Operational policy type implementations.

This policy type defines policies to assist in coordinating multiple control loops during runtime. This policy type is developed using XACML PDP to support question/answer policy decisions at runtime for the onap.policies.controlloop.operational policy types.
The unit of execution and scaling in the Policy Framework is a PolicyImpl entity. A PolicyImpl entity runs on a PDP. As is explained above a PolicyImpl entity is a PolicyTypeImpl implementation parameterized with a TOSCA Policy.

In order to achieve horizontal scalability, we group the PDPs running instances of a given PolicyImpl entity logically together into a PDPSubGroup. The number of PDPs in a PDPSubGroup can then be scaled up and down using Kubernetes. In other words, all PDPs in a subgroup run the same PolicyImpl, that is the same policy template implementation (in XACML, Drools, or APEX) with the same parameters.
The figure above shows the layout of PDPGroup and PDPSubGroup entities. The figure shows examples of PDP groups for Control Loop and Monitoring policies on the right.
The health of PDPs is monitored by the PAP in order to alert operations teams managing policy. The PAP manages the life cycle of policies running on PDPs.
The table below shows the methods in which PolicyImpl entities can be deployed to PDP Subgroups
Method | Description | Advantages | Disadvantages |
---|
Cold Deployment | The PolicyImpl (PolicyTypeImpl and TOSCA Policy) are predeployed on the PDP. The PDP is fully configured and ready to execute when started. | No run time configuration required and run time administration is simple. | Very restrictive, no run time configuration of PDPs is possible. |
Warm Deployment | The PolicyTypeImpl entity is predeployed on the PDP. A TOSCA Policy may be loaded at startup. The PDP may be configured or reconfigured with a new or updated TOSCA Policy at run time. | The configuration and parameters of the PDPs in a PDP group may be changed at run time by loading or updating the TOSCA Policy of the PDP Group at run time. Lifecycle management of TOSCA Policy entities is supported, allowing features such as PolicyImpl Safe Mode and PolicyImpl retirement. | Administration and management is required. The configuration and life cycle of the TOSCA policies can change at run time and must be administered and managed. |
Hot Deployment | The PolicyImpl (PolicyTypeImpl and TOSCA Policy) are deployed at run time. The PolicyImpl (PolicyTypeImpl and TOSCA Policy) may be loaded at startup. The PDP may be configured or reconfigured with a new or updated PolicyTypeImpl and/or TOSCA Policy at run time. | The policy logic, rules, configuration, and parameters of the PDPs in a PDP group may be changed at run time by loading or updating the PolicyTypeImpl and TOSCA Policy of the PDP Group at run time. Lifecycle management of TOSCA Policy entities and PolicyTypeImpl entites is supported, allowing features such as PolicyImpl Safe Mode and PolicyImpl retirement. | Administration and management is more complex. The PolicyImpl itself and its configuration and life cycle as well as the life cycle of the TOSCA policies can change at run time and must be administered and managed. |

For Dublin, the DCAE microservice component developer will use TOSCA-LAB to generate a specific yaml for their microservice component. These can be now loaded into the policy framework using the Policy Lifecycle API using the onap.monitoring domain. TOSCA-LAB produces the following example yaml:

pdp_types:
- XACML
Now that domain is available to CLAMP for creating concrete policies creation.
While designing a control loop using CLAMP, a Control Loop Designer will use the Model Schema for a specific DCAE mS component Policy Model and create a specific Policy.

For CLAMP to deploy policies, we need to make sure there is a simple default way for this to support Dublin.

Policy decisions are required by ONAP components to support the policy-driven ONAP architecture. Currently implemented using the XACML PDP.
