APPC

• Receive ConfigScaleOut(VNF_ID, VF_Module_ID)
• Obtain Configuration information for new instance from A&AI

CLAMP

• Ensure CLAMP has access to VF_Module_Type at design time
• Create policies for Scaling of vDNS  
• Create Guard policies for Auto Scale Out

DCAE

• PAM (Are there any impacts to DCAE to get it to send Scaling data to Policy?) 

OOF

• OOF will process Homing and license placement request from MSO.

OOF will support additional Policies for Scale Out to check the following:

• If there is enough capacity in the region or close to the region
• For the VNF Instance, is the license sufficient to satisfy the configuration requested

Modeling

• Need to add Controller type to the VNF Model in SDC 

Policy 

• Create API call to SO with VNFInstanceID and VF_Module_Type as arguments
• Set up proper Guard Policies
• Compare number of instances to both Min and Max values
• Check Prov_Status = PROV

SDC

• Add Controller_Type to VNF Model.  This should be one of: APPC, SDNC, VF-C??? 

SDNC

• Import Scaling changes from APPC so that all configuration changes may be done on VNFs controlled by SDNC
• After Resource Assignment for new instance, IP Addresses need to be added to AAI 

SO

• Create API for VID and Policy to call that will allow SO to scale a VNFC
• Create work flow to get all needed information to Scale a VNFC
• Call API for Homing and Licensing checks
• Create Workflows using Workflow Designer 

VID

• Change Manual Scaling Use Case to use the same SO API that Policy is using in Auto Scaling Use Case (Common Actor API)
