Dmaap on the topic "unauthenticated.TPCE" through a POST request on /events/unauthenticated.TPCE
It uses Jackson to serialize the notification to JSON and jersey client to send the POST request.
+odl-transportpce-nbinotifications
+---------------------------------
+
+This feature allows TransportPCE application to write and read notifications stored in topics of a Kafka server.
+When the feature is called to write notification to a Kafka server, it will serialize the notification
+into JSON format and then will publish it in a topic of the server.
+When the feature is called to read notifications from a Kafka server, it will retrieve it from
+the topic of the server and will deserialize it.
+
+For now, when the REST RPC service-create is called to create a bidirectional end-to-end service,
+depending on the success or the fail of the creation, the feature will notify the progression of
+the creation to a Kafka server. The topics that store these notifications are named after the connection type
+(service, infrastructure, roadm-line). For instance, if the RPC service-create is called to create an
+infrastructure connection, the service notifications related to this connection will be stored in
+the topic 'infrastructure'.
+
+The figure below shows an example of the application nbinotifications in order to notify the
+progress of a service creation.

+ :alt: Example of service notifications using the feature nbinotifications in TransportPCE
+
+
+Depending of the success of the service creation, different notifications will be published
+to the topic 'service' of the Kafka server.
+
+
+- **ServiceCreate request received** : Indicates that TransportPCE received an RPC request service-create
+ and started the process of creation. The notification contains all information concerning
+ the new service to create.
+
+
+If the service was correctly implemented, these notifications will be published :
+
+
+- **PCE calculation done OK !** : Indicates that the PCE calculation requested by the service-create
+ was successful. It also contains all information concerning the new service to create.
+- **Service implemented !** : Indicates that the service was successfully implemented.
+ It also contains all information concerning the new service.
+
+
+Otherwise, this notification will be published :
+
+
+- **ServiceCreate failed ...** : Indicates that the process of service-create failed.
+ It contains the failure response.
+
+To retrieve these service notifications stored in the Kafka server :
+
+**REST API** : *POST /restconf/operations/nbi-notifications:get-notifications-service*
+
+**Sample JSON Data**
+
+.. code:: json
+
+ {
+ "input": {
+ "connection-type": "service",
+ "id-consumer": "consumer",
+ "group-id": "test"
+ }
+ }
+
+.. note::
+ The field 'connection-type' corresponds to the topic that store the notifications.

Help
----
- This feature is considered experimental. It provides a REST client in order to send TPCE notifications
to ONAP Dmaap Message router.
+- **feature odl-transportpce-nbinotifications**
+
+ - This feature is considered experimental. It provides transportPCE with connectors in order to read/write
+ notifications stored in topics of a Kafka server.
+
How To Start
------------
feature:install odl-transportpce-dmaap-client
+If you need the NBI-notifications support, before installing odl-transportpce-nbinotifications feature,
+make sure to run ZooKeeper and then the Kafka server.
+By default, it is considered that the Kafka server is installed in localhost and listens on the 9092 port,
+if it isn't the case then set the KAFKA_SERVER environment variable of your system or
+modify the file *'transportpce/features/odl-transportpce-nbinotifications
+/src/main/resources/org.opendaylight.transportpce.nbinotifications.cfg'*::
+
+ suscriber.server=${env:KAFKA_SERVER:-[IP_ADDRESS]:[PORT]}
+ publisher.server=${env:KAFKA_SERVER:-[IP_ADDRESS]:[PORT]}
+
+*where [IP_ADDRESS] and [PORT] are respectively the IP address and the port that host the Kafka server.*
+
+After that, run in karaf::
+
+ feature:install odl-transportpce-nbinotifications
+
