+5G - PNF Plug and Play

+Description
+~~~~~~~~~~~
+
+The PNF PnP flow is a method, which allows to register within ONAP/AAI a PNF resource instance.
+This PNF resource instance is correlated with an existing service instance.
+PNF Plug and Play is used to register a PNF when it comes on-line.
+This use case is intended to be applicable to a variety of PNFs such as routers and 5G base stations.
+The steps and descriptions have been drafted to be as general as possible and to be applicable
+to a relatively wide variety of PNFs. However, the use case was originally developed with a consideration
+for 5G PNF Distributed Units (DU).

+How to Use
+~~~~~~~~~~
+
+1) `Create and distribute service model which contains PNF <https://wiki.onap.org/display/DW/5G+-+PNF+PnP+-+Integration+Test+Cases#id-5G-PNFPnP-IntegrationTestCases-CreateanddistributeservicewhichcontainsPNF>`_
+2) `Create service for PNF and wait for PNF Ready message in DmaaP topic <https://wiki.onap.org/display/DW/5G+-+PNF+PnP+-+Integration+Test+Cases#id-5G-PNFPnP-IntegrationTestCases-PNFReady>`_
+3) `Send PNF Registartion request from PnP PNF Simualtor and finish registration <https://wiki.onap.org/display/DW/5G+-+PNF+PnP+-+Integration+Test+Cases#id-5G-PNFPnP-IntegrationTestCases-PNFregistrationacceptingwhenAAIentrycreatedinadvance>`_
+
+
+Known Issues and Resolutions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In SO BPMN in mechanism making re-subscription to /events/unauthenticated.PNF_READY topic there is an issue `SO-1253 <https://jira.onap.org/projects/SO/issues/SO-1253>`_.
+By default after ONAP and PRH deploy DMaaP topic /events/unauthenticated.PNF_READY is not present.
+It is created by PRH after first expected PNF registration event arrival to ONAP system.
+If service for PNF will be created before topic /events/unauthenticated.PNF_READY will be present then service will not be able to read from the topic.
+
+
+**Workaround**
+
+- Before starting any PNF service verify if unauthenticated.PNF_READY topic exists using command:
+
+::
+
+   curl --header "Content-type: application/json" --request GET http://<kubernetes slave IP>:30227/topics/listAll
+
+- If it doesn't exists send following curl in order to create topic:
+
+::
+
+   curl --header "Content-type: application/json" --request POST --data '[{"correlationId": "test"}]' http://<kubernetes slave IP>:30227/events/unauthenticated.PNF_READY
+
+- Once again verify if topic exists
+- If the PNF service will be started before unauthenticated.PNF_READY topic creation, then there will be a need to restart SO-BPMN docker container
