Overview

SON-Handler application acts upon reception of  two types of events (Measurement and Fault events) and Neighbor list change notification from SDNR.

Fault events are sent whenever collisions/confusions found by the Ran-simulator due to pci changes and at the same time SDNR notification is also sent whenever there is change in pci value.Measurement events are periodically sent from Ran-simulator which gives the KPI information.

SON-Handler processes the events and calls OOF for global optimization. Then it determines the actions based on OOF response and writes to unauthenticated.DCAE_CL_OUTPUT for policy to take necessary actions.

Deployment Prerequisite/dependencies

SON-Handler service requires DMAAP and Policy components to be functional.

SON-hadler service requires  the following dmaap topics to be present in the running DMAAP instance :

1.PCI-NOTIF-TOPIC-NGHBR-LIST-CHANGE-INFO

2.unauthenticated.SEC_FAULT_OUTPUT

3.unauthenticated.SEC_MEASUREMENT_OUTPUT

4.DCAE_CL_RSP

Policy model required for SON-handler service should be created and pushed to policy component.

Deployment Steps

  • Copy sonhms-blueprint and inputs file to /blueprints directory in DCAE bootstrap POD
  • Log-in to the DCAE bootstrap POD's main container

  • validate and deploy blueprint

    Deploy component
     cfy install -b sonhms -d sonhms -i <inputsFilePath> <blueprintFilePath>

  • undeploy

    Undeploy component
    cfy uninstall sonhms


  • delete blueprint

    Delete blueprint
    cfy blueprints delete sonhms

Validation

The status of service can be checked after the deployment using command "kubectl get pods --namespace onap |grep son"

Verify
ubuntu@k8s-dcae-1:~$ kubectl get pods --namespace onap | grep son
