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. + +|clamp-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. + +|dashboard-flow| + +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. + +|closed-loop| + +.. |clamp-flow| image:: images/architecture/distdepl.png +.. |dashboard-flow| image:: images/architecture/monitoring.png +.. |closed-loop| image:: images/architecture/ONAP-closedloop.png |
