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.

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

Interfaces:

1. Mount Request to SDN-R

<node xmlns="urn:TBD:params:xml:ns:yang:network-topology"> 
<node-id>new-netconf-device id</node-id> 
<host xmlns="urn:opendaylight:netconf-node-topology">127.0.0.1</host> 
<port xmlns="urn:opendaylight:netconf-node-topology">17830</port> 
<username xmlns="urn:opendaylight:netconf-node-topology">admin</username> 
<password xmlns="urn:opendaylight:netconf-node-topology">admin</password> 
<tcp-only xmlns="urn:opendaylight:netconf-node-topology">false</tcp-only> 
</node> 

     2. New Feature at SDN-R to publish the cm-handle

      feature: addCMHandle

      Dmaap Topic: CM_HANDLE (TBC)

    3. Receive the DMaap notification

      curl -k --header "Content-Type: application/json" --request GET https://<ip>:30226/events/CM_HANDLE

    4. Fetch the yang model and intial config data from SDN-R using RESTConf API

       Yang model: https://<ip>:<port>/restconf/operations/network-topology:network-topology/topology/topology-netconf/node/{node-id}/yang-ext:mount/ietf-netconf-monitoring:get-schema

       Initial-config data: https://<ip>:<port>/restconf/config/network-topology:network-topology/topology/topology-netconf/node/{node-id}/yang-ext:mount/ran-network:ran-network
