Discussion about Messageflows for CMNotify from VES-Collector to "RuntimeDB". 

• Options:
  • RuntimeDB listen on DMaaP as described: 
    ARCHCOM: InfoFlow - RunTime Config DB Information Flow#3.1FLOW1:VESInformationFlowCMNotify-WritingtoRunTimeDB 
    • Fits to the overall ONAP architecture
  • SDN-R listen on DMaaP and a function or µService updates RuntimeDB 
    • Comment: such function or µService for sure under the responsibility for RuntimeDB - SDN-R is not involved - however such function or µService coudl or could not deploy together with SDN-R → this could be a deployment option and would need to be configured by OOM helm charts.
    • This option is not discussed and specificed and does not fit much into the ONAP architecture. 

Discussion about Messageflow from "RuntimeDB" to NetConf Servers

• According to ARCHCOM: InfoFlow - RunTime Config DB Information Flow#3.1FLOW4:ControllerSendingConfigurationInfoUpdateFlow-WritingtoRunTimeDB the controller listen on a related topic and forwards the message body to the addressed NetConf Server. Details need to be specified - SDN-R has the infrastructure for this message flow available.
