Goal: Auto VNF Configuration (Frankfurt)

This goal is about using CDS in place of CDT so that we can move to a more automated configuration process rather than having to preload information into CDT and then sending pointers to that information through VID and SO to APPC/SDNC.

APPC

  • Adopt CDS for use in Auto Configuration 
  • Change ConfigScaleOut to support Auto Configuration 

SDNC

  • Adopt CDS for use in Auto Configuration
  • Change ConfigScaleOut to support Auto Configuration 

SO

  • Change APPC/SDNC API usage to adopt Auto Configuration  
  • Change Controller table in SO to point to CDS

Goal: Manual Scaling Multiple Instances (Future)

Manually instantiate multiple instances of the same VF_Module with a single action

SO

  • Change Scale Out Request API to include number of instances to scale
  • Create workflow that will add the correct number of instances received from VID

VID

  • Add field in Scale Out Screen to allow multiple instances for scaling
  • Update Scaling Call to SO to include the number of instances


Goal: Scheduling of Manual Scaling (Future)

Allow for a manual scaling action to take place in the future

OOF

  • Integrate Scaling actions with Scheduler

VID

  • Integrate Scaling actions with Scheduler


Goal: Homing and Capacity Check (Future)

Check with OOF to ensure there is enough capacity to home the resources before the resources are requested from the platform

OOF

  • Support a Homing and Capacity Check  Function (Priority: 4)

SO

  • Call Homing and Capacity API on OOF  (Priority: 4)


Goal: Pre and Post Action Signaling to VNF (Future)

Create signals to the VNF before an action takes place and after an action is completed so that the VNF can prepare for the action and then run checks or finalize setup after the action is complete.
