1. Impacted components: SDNC, APPC
2. Contributors: AT&T, Orange, Intel
3. Functionalities
   1. For Casablanca, we will focus on the LCM action necessary for traffic migration. For Dublin and beyond, we will create a workflow within SO for traffic migration.
   2. MigrateTraffic LCM action (Alternative is ConfigModify LCM action is PTLs recommend to push MigrateTraffic LCM to Dublin)Common API definition for traffic migration
      
      1. Source, destination nodes - pool
      2. Flow distribution policy - equal distribution for e.g.
      3. Anchor points - e.g., DNS for layer-4+ VNFs
      4. Fine-grained flow filter
      5. Failure handler
   3. Mechanisms for traffic migration - implemented by controller
      1. Assessment report on commonalities/differences across VNF types – e.g., IP based redirection, DNS based or load balancer
4. Integration/testing
   
   1. For Casablanca, we will demonstrate traffic migration across 2 vFWs using traffic source as the anchor point
   2. Ansible playbook for adjusting the traffic weight on the traffic source (anchor point)
