 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.

 The ONAP CLAMP platform abstracts the details of these systems under the concept

 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

 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.
