AAI

• May need some named queries to help traverse AAI and gather Instance information 

APPC

• ConfigScaleIn
  • APPC will support a new LCM action ConfigScaleIn
  • APPC will need to support accepting a new ConfigScaleIn request from MSO
  • APPC will accept the payload sent from MSO. Included in the request will be the VF Module ID to be removed.
  • APPC will send the ConfigScaleOut request to the VNF via REST API
• Pre Action Phase
  • Need to decide what tasks we will execute in this phase so that we can write the requirements "How"
• Post Action Phase
  • Need to decide what tasks we will execute in this phase so that we can write the requirements "How"
• Distribute_Traffic
  • APPC will accept and process a DistributeTraffic request from MSO via DMaaP
  • DistributeTraffic action will be enhanced to specify a VM as the target
• Quiesce_traffic for VNFCs
  • APPC will accept and process a QuiesceTraffic request from MSO via DMaaP
  • QuiesceTraffic action will be enhanced to specify a VM as the target

Design Time Requirements:

Run Time Requirements:

CLAMP

• Scale In Target
• monitoring policies 

SDC

• Import Scaling Building Blocks to Catalog (This assumes WF designer will be used)
  • Add Scale In Building Block to SDC Catalog

  • QuiesceTraffic action will be enhanced to specify a VM as the target

Design Time Requirements:

Run Time Requirements:

SO

• Scale In Workflow
  • Support a new Scale In Building Block.
  • Support a sending and receiving messages from Policy and VID via DMaaP
  • Accept a Closed Loop (Policy) or Open Loop(VID) request to Scale In a module
  • Support sending a Scale In Request to the Controller. This request will include the VF-Modules/VM(s) that will be deleted
• Scale In Target
• Support Pre Action Phase
  • Same comment as previous 
• Support Post Action Phase
  • Same comment as previous
•  DistributeTraffic Action. T
  • Enhance the DistributeTraffic action at a VM level and send to the Controller. This assumes that the action has been implemented and tested in Casablanca release. The necessary config parameters will be passed with the request to the Controller
• Call QuiesceTraffic (TBD if this action will be use din this workflow)
• Scaling Building Blocks

VID

• UI enhancements
  • Support new field to specify which VM(s) to remove in the Scale In Request to SO
  •  Is VID going to call policy to determine which VM to remove or will a user enter the information on the GUI
  • Support Common DMaaP interface to send request to SO

APPC

• Pre Action phase for Scale Out 
• Post Action Phase for Scale Out

SDNC

• Pre Action phase for Scale Out 
• Post Action Phase for Scale Out

SO
