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, those blueprint are either:
    •  sent by SDC to DCAE(inventory) via SDC distribution. 
    • or sent by DCAE-MOD to DCAE(inventory)
  • Create configuration policy from the policy Tosca sent by SDC-model Tosca, the tosca policy-model are either:
    •  sent by SDC via SDC distribution to everyone
    • or query by CLAMP to Policy. in this case the policy-model is either pre-provison in Policy
      or separately provision to Policy via the REST API exposed by Policy.
  •  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.
