+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+
+************
+Introduction
+************
+
+This use case is a non-real-world closed-loop use case to demonstrate automated recovery when the front-haul connection between an O-DU and O-RU is reset.
+An application in the NONRTRIC senses the fault from the O-RU (O1-FM) and initiates a NETCONF reset operation (O1-CM) using the OAM controller.
+More details about the use case can be found on the O-RAN SC wiki: `RSAC <https://wiki.o-ran-sc.org/pages/viewpage.action?pageId=20878423>`_ and `OAM <https://wiki.o-ran-sc.org/display/OAM/Closed+loop+use+case>`_.
+
+Non-RT RIC provides multiple implementation versions of the recovery part of the use case. One in the form of a python
+script, one utilizing the ONAP Policy Framework, and one Go version that utilizes Information Coordination Service (ICS).
+
+The code is available in the `use case repo <https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric%2Frapp%2Forufhrecovery.git;a=summary>`_
+
+Standalone Script Solution
+++++++++++++++++++++++++++
+
+The script version consists of a python script that performs the tasks needed for the use case. There are also two
+simulators. One message generator that generates alarm messages, and one SDN-R simulator that receives the config
+change messages sent from the script and responds with alarm cleared messages to MR.
+
+All parts are Dockerized and can be started as individual containers, in the same network, in Docker.
+
+ONAP Policy Solution
+++++++++++++++++++++
+
+There is also another solution for performing the front-haul recovery that is based on `ONAP Policy Framework <https://wiki.onap.org/display/DW/Policy+Framework+Project>`_.
+A TOSCA Policy has been created that listens to DMaaP Message Router, makes a decision on an appropriate remedy and then signals the decision as a configuration change message via
+REST call to the OAM controller.
+
+There is a `docker-compose <https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric.git;a=tree;f=docker-compose/docker-compose-policy-framework>`_ available
+in the nonrtric repo for bringing up the complete standalone version of ONAP Policy Framework.
+
+The detailed instructions for deploying and running this policy are provided in
+the `wiki <https://wiki.o-ran-sc.org/display/RICNR/O-RU+Fronthaul+Recovery+usecase>`_.
+
+ICS Consumer Solution
++++++++++++++++++++++
+
+The ICS Consumer solution is implemented in Go and instead of polling MR itself, it registers as a consumer of the "STD_Fault_Messages" job in ICS.
+
+O-DU Slice Assurance
+--------------------
+
+A very simplified closed-loop rApp use case to re-prioritize a RAN slice's radio resource allocation priority if sufficient throughput cannot be maintained. Not intended to to be 'real-world'.
+
+The Go implementation of the solution can be found in
+this `link <https://gerrit.o-ran-sc.org/r/gitweb?p=nonrtric/rapp/ransliceassurance.git;a=tree;f=smoversion>`__.
