Overview

CPS stores the yang model of the mounted devices in CPS-Core database. It is handled by CPS-DMI Plugin which fetches the yang models of the devices registered at AAI and stores in CPS.

As the VNF/PNF registry in AAI is not supported for Slicing use case, the mounted nodes will be directly published to the CPS-DMI Plugin by SDN-C.

A new karaf feature is needed to communicate the node-id to CPS-DMI plugin. This will be achieved by registering a cm-handle with DMI-Plugin.

RPC Details

Functionality:

  1. This RPC makes use of the onDataTreeChanged event from DataTreeChangeListener to detect, if any node is added to network-topology https://localhost:8086/restconf/config/network-topology:network-topology

  2. If the ModificationType is 'WRITE', a new notification is published to dmaap to add the cmhandle.

  3. If the ModificationType is 'DELETE', the notification to remove the cmhandle will be published. - TBC with CPS Team
