Requirements for the Non-RT RIC project
==========================================
The non-functional requirements are the following ones:
-#. Non-RT RIC shall not update the same policy or configuration parameter for a given near-RT RIC or RAN function more often than once per second.
-#. Non-RT RIC shall be able to update policies in several near-RT RICs.
+#. Non-RT RIC shall not update the same policy or configuration parameter for a given Near-RT RIC or RAN function more often than once per second.
+#. Non-RT RIC shall be able to update policies in several Near-RT RICs.
Moreover, there are functional requirements regarding the A1 interface:
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 NearRT RICs
+ * 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 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.
