-Non-RT RIC Overview
-===================
+Requirements for the Non-RT RIC project
+==========================================

-A-release architecture
-----------------------
-
-The architecture is as shown on the following picture:
-
-.. image:: ./images/architecture.png
-   :scale: 50 %
-
-The A1 controller is located in SDNC, an ONAP component. It communicates with ORAN via the A1 interface with the Near-RT RIC simulator.
-
-On the other end, it is accessible via a dashboard, that allows to interact with policies. The dashboard itself is split into the backend and the frontend, and can be deployed following the instructions on the `human interfaces page`_.

-Requirements for the Non-RT RIC project
----------------------------------------

 There are functional requirements emitted by O-RAN WG2 for the Non-RT RIC, which are the following:
 
-1. Non-RT RIC shall support data retrieval and analysis; the data may include performance, configuration or other data related to the application (recommended data shown in required data section for  different use cases).
-2. Non-RT RIC shall support relevant AI/ML model training based on the data in 1. for non-real-time optimization of configuration parameters in RAN or Near-RT RIC, as applicable for the use case.
-3. Non-RT RIC shall support relevant AI/ML model training based on the data in 1. for generating/optimizing policies and intents to guide the behavior of applications in Near-RT RIC or RAN, as applicable for the use case.
-4. Non-RT RIC shall support training of relevant AI/ML models based on the data in 1. to be deployed/updated in Near-RT RIC as required by the applications.
-5. Non-RT RIC shall support performance monitoring and evaluation.
-6. Non-RT RIC shall support a fallback mechanism to prevent drastic degradation/fluctuation of performance, e.g. to restore to the previous policy or configuration.

+Policy Agent Overview
+=======================
+
+The Policy Agent maintains a transient ropository of the following items to support R-Apps:
+
+ * All NearRT 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 NearRT RICs
+ * All configured Policy instances in the network
+
+It provides an NBI for the R-Apps (and for the dashboard) 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 NearRT 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 NonRT RIC:
+
+      - OSC API, which is influenced by the A1 standard
+      - The NonRT RIC simulator, which supports the A1 standard with a number of not yet CRs included.
+ * To an ONAP style controller.

+
+Dashboard Overview
+===================
+
+The NonRT RIC Dashboard is a graphical user  user interface that enables the user to manage the Policies in the network. The dashboard interacts with the Policy agent via a REST API.
+The dashboard generates its GUI from JSON schemas in a model driven fashion.
+
+The dashboards consists of a back end implemented as a Java Springboot application and a fronted developed using the Angular framework.
