Use Case Authors:

...

• Service and resource on-boarding
• Service configuration
• Service termination 
• Self service adaptation (Bandwidth on demand  to be added)
• Auto-scaling based on  fault and performance (stretch goal)
• fault detection and auto-healing (stretch goal)
• data correlation and analytics (stretch goal)

...

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

5.1 DCAE Flow in Close Loop

1. RestConf Collector (RC) requests to set up a long term tunnel with the 3rd party SOTN Controller
2. SOTN Controller responses with OK upon successful tunnel setup
3. SOTN Controller pushes service route status data to the collector
4. RC receives data, converts it into JSON format and publishes on DMAAP with topic of ROUTE_ALARM_OUTPUT
5. (TBD)  

6. Service Design Flow

• 1. Design the service in SDC portal
• 2. SDC distribute the service information to SO
• 3. SDC distribute the service network information to SDNC
• 4. SDC distribute the service model information to AAI
• 5. SDC distribute the service VNF information to VFC/APPC.
