 Clamp in ONAP Architecture
 --------------------------

 CLAMP is a platform for designing and managing control loops. It is used to visualize
 a control loop, configure it with specific parameters for a particular network
 service, then deploying and undeploying it.  Once deployed, the user can also
 update the loop with new parameters during runtime, as well as suspending and
 restarting it.

 It interacts with other systems to deploy and execute the control loop. For
 example, it gets the control loop blueprint from SDC - DCAE-DS.
 It requests from DCAE the instantiation of microservices
 to manage the control loop flow.  Furthermore, it creates and updates multiple
 policies in the Policy Engine that define the closed loop flow.

 The ONAP CLAMP platform abstracts the details of these systems under the concept
 of a control loop model.  The design of a control loop and its management is
 represented by a workflow in which all relevant system interactions take
 place.  This is essential for a self-service model of creating and managing
 control loops, where no low-level user interaction with other components is
 required.

 CLAMP also allows to visualize control loop metrics through a dashboard, in order
 to help operations understand how and when a control loop is triggered and takes action.

 At a higher level, CLAMP is about supporting and managing the broad operational
 life cycle of VNFs/VMs and ultimately ONAP components itself. It will offer the
 ability to design, test, deploy and update control loop automation - both closed
 and open. Automating these functions would represent a significant saving on
 operational costs compared to traditional methods.
