So CLAMP must be seen now +as a function provided by the Policy Framework project. + +CLAMP is a function for designing and managing control loops and a UI to manage Policies. +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. + +Starting with Istanbul release, CLAMP GUI can also be used to create/read/update/delete/list policies +outside of a control loop, and therefore CLAMP is also the front-end for Policies management in ONAP. + +CLAMP interacts with other systems to deploy and execute the control loop. For +example, it extracts the control loop blueprint from CSAR distributed by SDC. +CLAMP also calls the internal Policy framework API to get the Policy Models(Model Driven Control Loop) +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 function 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. + +At a higher level, CLAMP is about supporting and managing the broad operational +life cycle of VNFs/VMs and ultimately ONAP components itself. It offers the +ability to design, test, deploy and update control loop automation - both closed +and open. Automating these functions represents a significant saving on +operational costs compared to traditional methods. + +|closed-loop| + +.. |clamp-flow| image:: images/architecture/distdepl.png +.. |closed-loop| image:: images/architecture/ONAP-closedloop.png diff --git a/docs/clamp/clamp/clamp.rst b/docs/clamp/clamp/clamp.rst index b9853f88..9b5e9019 100644 --- a/docs/clamp/clamp/clamp.rst +++ b/docs/clamp/clamp/clamp.rst @@ -1,6 +1,203 @@ ..
