- Impacted components: SDNC, APPC
- Contributors: AT&T, Orange, Intel
- Functionalities
- Common API definition for traffic migration
- Source, destination nodes - pool
- Flow distribution policy - equal distribution for e.g.
- Anchor points - e.g., DNS for layer-4+ VNFs
- Fine-grained flow filter
- Failure handler
- Mechanisms for traffic migration - implemented by controller
- Assessment report on commonalities/differences across VNF types – e.g., IP based redirection, DNS based or load balancer
- Common API definition for traffic migration
- Integration/testing
- For Casablanca, we will demonstrate traffic migration across 2 vFWs using traffic source as the anchor point
- Ansible playbook for adjusting the traffic weight on the traffic source (anchor point)
- Use case across different VNF types – vGW/vCPE, vFW, vLB, vDNS
- Develop recipe (using Ansible, NETCONF or REST) for traffic migration depending on the protocol used to communicate with the VNF
Execution flow:
User → DMAAP → SDNC/APPC → Ansible → VNF(s)
