-Policy Agent Overview
-=======================
-
-The Policy Agent maintains a transient repository of the following items to support R-Apps:
-
- * All Near-RT RICs in the network. This information is configured using the ONAP CDS database (which is using the Cloudify Consul database).
- * All Policy types for all Near-RT RICs
- * All configured Policy instances in the network
-
-It provides an NBI for the R-Apps (and for the Control Panel) for policy management. This is a REST API.
-As an option, policy management can also be done via asynchronous messages through ONAP/Dmaap.
-The NBI provides support for an R-APP to locate the correct Near-RT RIC based on identifiers as defined in O1.
-
-The agent monitors all Near-RT RICs and recovers from data inconsistencies, which may happen when (for instance) an Near-RT RIC restarts.
-
-The R-Apps can be monitored so that their Policies can be automatically removed when an R-App is stopped/removed.
-
-On its southbound side the agent can connect to a number of different A1 providers:
-
- * Directly to the Non-RT RIC:
-
-      - OSC API, which is influenced by the A1 standard
-      - The Non-RT RIC simulator, which supports the A1 standard with a number of not yet CRs included.
- * To an ONAP style controller.
