Introduction

This is considered as an extension of MDONS use case from ONAP Frankfurt release.

Business Value

Design & Implementation

The scope of code change will be very limited with the existing capability at ONAP CLAMP, DCAE and POLICY components. Given the fact that FNC Virtuora MSA support has already delivered

L0/L1 alarms and PM data in VES (CEDM) (7.0 version) format. However, those delivered through TAPI APIs are retrieved from FPM server and converted into TAPI standard in Json format.

  1. SDC/DCAEMOD/Policy Portal design and activate policy.
  2. Policy config and activate the policy.
  3. SDC/DCAEMOD distribute the DCAE config.
  4. SDC/DCAEMOD/HOMES UI distribute the alarm correlation rules to Holmes.
  5. 3rd party domain controllers report link down alarm to DCAE
  6. DCAE will do data cleaning and filtering for the alarms
  7. DCAE keep track the data.
  8. Holmes do analysis for the alarms.
  9. Holmes notify the reroute event.
  10. Policy matching the reroute rules.
  11. Policy call SO or SDNC to delete the old services and create the new services. For the creation flow, a variable route will be recalculated.

RestConf Collector (RCC)

In MDONS use case, prior to subscribing to topics to get event notifications. We manually register 'DCAE' in the domain controller (DC). Once registration is successful, system can subscribe to different topics of DC to get event notification. It is mandatory to pass 'notification URL' to DC so that when event occurs it posts notification to that URL.

Since MSA notification is already in VES format, it could be posted directly on to DMAAP with relevant topic to be consumed by Hulmes directly. If RCC does not support such configuration, then a 1n1 attribute mirroring mapping xml file need to be designed to feed the data into the existing flow.
