| 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 extracts the control loop blueprint and Policy Model(Model Driven Control Loop) |
| from CSAR distributed by SDC/DCAE-DS. |
| It requests from DCAE the instantiation of microservices |
| to manage the control loop flow. Furthermore, it creates and updates multiple |
| policies (for DCAE mS configuration and actual Control Operations) 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. |
