1.4 Close Loop vDNS
This flow has the APPC to AAI query which moves the query from Policy to APPC.
There are no changes in the vDNS flow for R1. Originally we looked at moving the query from Policy to APPC but there were design details on executing the dnsscaling API call and whether APPC should call SO or MultiVIM directly that were not able to work out in time for R1. So we will continue with the original flow.

title CLAMP Closed Loop Design (Option A) for vFW and vDNS \nvFW and vDNS use the same flows but they are separate VNFs/Services\n Uses Policy GUI
participant ONAP_User
participant CLAMP
participant SDC
ONAP_User -> CLAMP : Create Control Loop from Template
CLAMP -> SDC : Query for Services and VNFs
ONAP_User -> CLAMP : Choose Service and VNF
CLAMP -> SDC : Query for Alarm data from VNFs
ONAP_User -> CLAMP : Create Operational Policy\nChooses Chain of Actions\nSave Policy
CLAMP -> PolicyGUI : Redirect to Policy GUI
ONAP_User -> PolicyGUI CLAMP : SelectString matcher Select TCA box,\nclicks and creates one or more \nassociated signature rules.\nAssociates them with the operational policy \ncreated earlier
note right : DCAE Design Template has default policies already defined/expressed
ONAP_User -> PolicyGUI CLAMP : Repeat as Operational Policy/Signature as needed\n(total 1 vFW, 1 vDNS)
PolicyGUI CLAMP -> Policy : Create Operational Policies
PolicyGUI CLAMP -> Policy : Create String Matcher to Policy association
note right: executed for both vFW and vDNS policies
CLAMP -> SDC : Distribute Blueprint
ONAP_User -> SDC : check in, test, certify Blueprint
note right: this could take quite a while (minutes to days) due to user interactions
ONAP_User -> SDC : Distribute Blueprint
|||, distribute Blueprint
SDC -> DMaaP : Distribute control loop for DCAE
DMaaP -> DCAE : Control Loop Blueprint
CLAMP -> DMaaP : Poll for distribution complete
