1. Impacted components: SDNC, APPC, VFC, SO
2. Contributors: AT&T, Orange, Intel
3. Functionalities
   1. 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
   2. 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. Use case across different VNF types – vGW/vCPE, vFW, vLB, vDNS
   2. Develop recipe (using Ansible, NETCONF or REST) for traffic migration depending on the protocol used to communicate with the VNF 

3)      5G RAN PNF Software upgrade
