1. RestConf Collector (RC)subscribes for remote failure alarm to SOTN Controller (SC) 
2. RC requests to set up a long term tunnel with the 3rd party SC
3. SC responses with OK upon successful tunnel setting
4. SC pushes service route status data to the collector
5. RC receives alarm data, converts it into JSON format and publishes on DMAAP with topic of ROUTE_ALARM_OUTPUT
6. UVA consumes the alarm message
7. UVA requests the RestConf2VES mapping
8. UVA converts json alarm into VES  event
9. UVA publishes the VES event on DMAAP for further correlation
