5 Policy Drools PDP Engine
6 ########################
11 The Drools PDP, aka PDP-D, is the PDP in the Policy Framework that uses the
12 `Drools BRMS <https://www.drools.org/>`__ to enforce policies.
14 The PDP-D functionality has been partitioned into two functional areas:
21 The PDP-D Engine is the infrastructure that *policy applications* use.
22 It provides networking services, resource grouping, and diagnostics.
24 The PDP-D Engine supports the following Tosca Native Policy Types:
26 - onap.policies.native.Drools
27 - onap.policies.native.drools.Controller
29 These types are used to dynamically add and configure new application controllers.
31 The PDP-D Engine hosts applications by means of *controllers*.
32 *Controllers* may support other Tosca Policy Types. The
33 types supported by the *Control Loop* applications are:
35 - onap.policies.controlloop.operational.common.Drools
38 **PDP-D Applications**
40 A PDP-D application, ie. a *controller*, contains references to the
41 resources that the application needs. These include networked endpoint references,
42 and maven coordinates.
44 *Control Loop* applications are used in ONAP to enforce operational policies.
47 The following guides offer more information in these two functional areas.
