Service_Designer -> SDC : Log into SDC Create/Test/Certify service, \nwith control loop DCAE flow
SDC -> CLAMP : Blueprint distribution
SDC : Create service
loop for all VNFs
note right
For simplicity, assume the designer
will create a control loop per VNF.
end note
SDC_Catalog -> VNF_Artifact : Find artifact
VNF_Artifact -> Service_1 : Add VNF to service.
SDC -> CLAMP : Go to CLAMP\nto create a Control Loop
CLAMP -> SDC_Catalog : Find DCAE Template
create collections DCAE_Template_1 #red-> DCAE_SCH : Blueprint distribution
DCAE_SCH -> DCAE_Inventory : Save blueprint
Operator -> CLAMP : Configuration of control loop
CLAMP -> Policy : Create Configuration and Operational Policies
Policy -> DCAE_Policy_Handler : Configuration Policy
CLAMP -> DCAE_Inventory : Get DCAE Service Id based on Distributed Parameters
note left
Steps 8 and 9 are involved when there is no
pre-deployment of control loop in DCAE

TODO: Update UML with correct terminology. Update UML to add SDC Service Distribution
example of policies, blueprints, api calls. etc.
Day N: Control Loop Deployment
Control Loop deployment happens when an instance of a Service is created.
TODO flow diagram
Day N: Runtime Flow of a Control Loop
The following is a control loop message flow, across DCAE, Policy and App-C. The sections afterward will describe the process for designing, configuring and instantiating this flow.
