CLAMP (Closed loop Automation Platform):

1 High Level Component Definition and Architectural Relationships 

The CLAMP functional entity provides the capability to manage runtime control loops.  It provides the capability to

  • Create control loop from DCAE blueprint sent by SDC
  • Create configuration policy from the policy Tosca sent by SDC
  •  Configure DCAE applications of the control loop
  • Associate µService configuration policies to the DCAE application
  • Configure the operations to be taken by the control loop (by creating/updating/deleting operational policies)
  • Deploy/un-deploy control loop flow (blueprints) to DCAE
  • Control loop visualization. 

CLAMP relies on Policy to communicate to App-C/VF-C/SDN-C/SO in runtime, hence these are not part of CLAMP 

2. API definitions

CLAMP provides the following interfaces: (add the link to the interfaces)

Interface NameInterface Definition Interface Capabilities
CLAMPE-1Control Loop Lifecycle Management Interface.   A user interface for:
  • Selecting the control loop flow
  • Entering configuration policy parameters
  • Entering operational policy parameters
  • Managing life cycle of DCAE control flow blueprint 
CLAMPE-2Control loop dashboard.  User interface to show the overall status of the control loop through DMAAP events

 Display and update:

  • Events received and actions taken on the control loop.

Note:   xxxI interface is a Component internal interface.  xxxxE interface is a component external interface

The current API documents can be found at:

CLAMP consumes the following Interfaces:

Interface NamePurpose Reason For Use
SDCE-6To receive the Control Loop Blueprint from SDCTo receive
PolicyE-2To create and configure the closed Loop Operational Policies and Configuration policies(DCAE Aps. Config.)
DCAEE-x Retrieve DCAE appplication status
DCAEE-y Deploy/remove DCAE application.

4. known system limitations

Runtime: None

Clamp data redundancy is dependent on Kubernetes and the persistent volume.

Clamp application redundancy HA relies on Kubernetes

5. Used Models

Clamp uses the following models:

  • Service model (received from SDC)
  • VNF model (received from SDC)
  • Policy Model.
