PolicyDevelopment creates policy artifacts in Nexus and supporting information in the Policy database. PolicyDeployment reads those artifacts from Nexus and the supporting information from the Policy database whilst deploying policy artifacts. Once the policy artifacts are deployed, they are handed over to PolicyExecution for run-time management. PolicyDeveloment interacts with ONAP design time components, and has no programmatic interface with PolicyDeployment, PolicyExecution or any other run-time ONAP components.
The diagram below shows a more detailed view of the architecture.
PolicyDevelopment creates sets of executable policies (ExecutablePolicySet) for a certain domain, which consist of policies (ExecutablePolicy) and parameters for those policies (PolicyParameters) that can execute on PDPs. Executable policies are created from domain policies (DomainPolicy) that have been created from template policies (ProtoPolicy).
PolicyDeployment uses the PAP to deploy an ExecutablePolicySet on a PDPGroup, a grouping of PDPs of a certain type using a certain deployment plan.
PolicyExecution uses the PAP and PDPs to monitor execution of the policies in the ExecutablePolicySet on the PDPGroup.
