Zu Qiang (Ericsson) Page for us to work on the TOSCA in here.

A Control Loop service template is made up of several components, those which represent applications, those which represent dynamic config schemas, and the actual node_templates which makes up the loop itself.

Applications can be a DCAE microservice, an operational policy, or any other application as long as it can be modeled, and the targeted ecosystem to has a participant client waiting for the event distributions from CLAMP via DMaaP Message Router.

Dynamic config on the other hand can be a monitoring policy, or any other resource that provides config to parts of the loop, can be updated after the run time phase has started and is supported by the components hosting the applications in the control loop.

1. Control Loop TOSCA file definition

1.1 Control Loop Component Definition 

A Control Loop Component that can be part of a control loop, it defines the components that partake in a control loop, and are implemented at run time by participants. The control loop component definition is truly dynamic and, as long as the participant that the control loop component definition relates to understands its definition, it can be anything. However, we have designed a base control loop component attribute that's generic and that can act as a good starting point.

1.2 Loop Definition

The loop definition is explicit in the node_templates within the topology_template,  a Control Loop node template is specified and any node tempalte specified in the Control Loop node tepolcate is part of the control loop managed by CLAMP.

The below example doesn't explicitly include any order, ordering of control loop execution is to be considered in the future which likely would lead to changes to this
