+# Service Management and Orchestration (SMO)
+
+This project focus on a docker-compose deployment solution for SMO/OAM Components.
+
+## Introduction
+
+With respect to OAM the SMO implements the O1-interface consumers.
+According to the O-RAN OAM Architecture and the O-RAN OAM Interface Specification,
+the SMO implements a NETCONF Client for configuration and a HTTP/REST/VES server
+for receiving all kind of events in VES format.
+
+The setup contains an OpenDaylight based NETCONF client and an ONAP VES Collector.
+
+## SMO OAM Components
+
+This docker-compose file starts a pre-configured, self-contained SDN-R solution
+with the following components.
+
+ * **Identity**
+ ... representing an KeyCloak based identity service for centralized user
+ management. Please note that the implementation does not support IPv6.
+ Therefore, its own network is required called 'DMZ'.
+ In this configuration the external https port is 8463.
+
+ * **SDN-R** single node instance
+
+ ... representing the NETCONF consumer on the Service Management and
+ Orchestration framework (SMO) for the O1 interface based on
+ ODL-Phosphorus.
+ SDN-R comes with is own web-portal the external port is 8463.
+
+ * **VES collector**
+
+ ... representing the VES (REST) provider at SMO for all kind of events. In this configuration the external https port is 8443.
+
+ * **DMaaP**
+ ... representing SMO DMaaP component, includes message-router
+
+## Prerequisites
+
+```
+$ cat /etc/os-release | grep PRETTY_NAME
+PRETTY_NAME="Ubuntu 20.04.2 LTS"
+
+$ docker --version
+Docker version 20.10.7, build 20.10.7-0ubuntu1~20.04.2
+
+$ docker-compose version
+docker-compose version 1.29.1, build c34c88b2
+docker-py version: 5.0.0
+CPython version: 3.7.10
+OpenSSL version: OpenSSL 1.1.0l 10 Sep 2019
+
+
+$ git --version
+git version 2.25.1
+
+```
+Please modify the /etc/hosts of your system.
+
+* \<your-system>: is the hostname of the system, where the browser is started
+
+* \<deployment-system-ipv4>: is the IP address of the system where the solution will be deployed
+
+For development purposes <your-system> and <deployment-system> may reference the same system.
+
+```
+$ cat /etc/hosts
+127.0.0.1 localhost
+127.0.1.1 <your-system>
+<deployment-system-ipv4> sdnc-web <your-system>
+<deployment-system-ipv4> identity <your-system>
+```
+
+It is beneficial (but not mandatory) adding the following line add the
+end of your ~/.bashrc file. I will suppress warnings when python script
+do not verify self signed certificates for HTTPS communication.
+
+```
+export PYTHONWARNINGS="ignore:Unverified HTTPS request"
+```
+
+Please ensure that you download and copy the required 3GPP OpenAPIs for VES-stndDefined
+message validation into the folder './solution/operation-and-maintenance/smo/oam/ves-collector/externalRepo'.
+
+Please follow the instructions in ./solution/operation-and-maintenance/smo/oam/ves-collector/externalRepo/3gpp/rep/sa5/MnS/blob/Rel16/OpenAPI/README.md.
+
+The following tree shows the successfully tested folder structure. It combines different versions of the schemas ('Rel16' and 'SA88-Rel16') using 3GPP branch names.

+
+## Usage
+
+### Bring Up Solution
+
+#### Short story
+
+The following commands should be invoked. More detailed can be found in the
+next chapters.
+
+```
+docker-compose -f smo/common/docker-compose.yml up -d
+# wait until the cpu load is low again
+python smo/common/identity/config.py
+
+docker-compose -f smo/oam/docker-compose.yml up -d
+# wait until the cpu load is low again
+
+docker-compose -f network/docker-compose.yml up -d
+# wait about 2min
+docker restart ntsim-ng-o-du-1122
+python network/config.py
+```
+
+#### Check (adjust if required) environment variables
+
+```
+nano smo/.env
+nano network/.env
+```
+
+The tested configuration uses the following external https ports:
+
+ * 8443 for the ves-collector
+ * 8453 for web access to ODLUX (SDNC_WEB_PORT)
+ * 8463 for the keyclock web administrator user interface.
+
+#### Startup solution
+
+Please note that it is necessary to configure first the identity service,
+before starting further docker images.
+
+The several docker-compose yml files must be started in the right order as listed below:
+
+```
+docker-compose -f smo/common/docker-compose.yml up -d
+python smo/identity/config.py
+```
+
+The python script configure the users within the identity service (keycloak).
+A system user (%USER) is also created with administration rights.
+
+
+```
+docker-compose -f smo/oam/docker-compose.yml up -d
+python smo/identity/config.py
+```
+
+Please wait about 2min until all the service are up and running.
+If you see the login page (https://sdnc-web:8453) you are good to go and can start the (simulated) network.
+
+```
+docker-compose -f network/docker-compose.yml up -d
+```
+
+Usually the first ves:event gets lost. Please restart the O-DU docker container(s) to send a second ves:pnfRegistration.
+
+```
+docker-compose -f network/docker-compose.yml restart ntsim-ng-o-du-1122
+python network/config.py
+```
+
+The python script configures the simulated O-DU and O-RU according to O-RAN hybrid architecture.
+
+O-DU - NETCONF Call HOME and NETCONF notifications
+O-RU - ves:pnfRegistration and ves:fault, ves:heartbeat
+
+![ves:pnfRegistration in ODLUX](docs/nstim-ng-connected-after-ves-pnf-registration-in-odlux.png "ves:pnfRegistration in ODLUX")
+
+'True' indicated that the settings through SDN-R to the NETCONF server were
+successful.
+
+SDN-R reads the fault events from DMaaP and processes them.
+Finally the fault events are visible in ODLUX.
+
+![ves:fault in ODLUX](docs/ves-fault-in-odlux.png "ves:fault in ODLUX")
+
+
+### Log files and karaf console
+
+#### ODL karaf.logs
+
+```
+docker exec -it sdnr tail -f /opt/opendaylight/data/log/karaf.log
+```
+
+#### ves-collector logs
+
+```
+docker logs -f ves-collector
+```
+
+### Customizing Solution
+
+'.env' file contains customizing parameters
+
+### Verification Solution
+
+#### Access to SDN-R ODLUX
+
+##### Login into SDN-R
+
+ https://sdnc-web:8453
+
+ User: admin // see .env file
+
+ Password: Kp8bJ4SXszM0WXlhak3eHlcse2gAw84vaoGGmJvUy2U
+
+In case of trouble, please update the commands with your customized '.env' file.
+
+### Terminate solution
+
+To stop all container please respect the following order
+
+```
+docker-compose -f network/docker-compose.yml down
+docker-compose -f smo/oam/docker-compose.yml down
+docker-compose -f smo/common/docker-compose.yml down
+```
+
+### Cleanup
+
+!!! be careful if other stopped containers are on the same system
+```
+docker system prune -a -f
+```
+### Troubleshooting
+
+In most cases the .env setting do not fit to the environment and need to be
+adjusted.
+
+Please make sure that the network settings to not overlap with other networks.
+
+The commands ...
+```
+docker ps -a
+docker-compose ps
