The CLAMP functional entity provides the capability to manage runtime control loopsAAI (Available and active inventory) function provides real-time views of the resource and services in managed by and their relationships.  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

  • Realtime views of the managed resources and services and their relationships

  • The relevance of the managed resources and services to the ONAP components.

  • It is a registry of the active, available and assigned assets.

  • It maintains a multidimenstional relationship amongst the managed services and resources. 

2. API definitions

AAI provides CLAMP provides the following interfaces:

Interface NameInterface Definition Interface CapabilitiesVersionStatusConsumed Models
AAIECLAMPE-1Control Loop Lifecycle Management Inventory Service 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.
  An interface to create, update, retrieve, query, delete the service, resources and relationship inventory information for:
  • Cloud infrastructure (including cloud infrastructure regions and availability zones, cloud infrastructure resources such as servers, storage, VLANs, cloud network technologies,...)
  • Paths and connectors
  • Business Customers and business customer relationship to managed assets
  • Service Instances (including the relationship to used resources)
  • Resource instances (including allotted resources) (virtual and physical, including VNFs, PNFs, Switches, VNF modules)
  • External systems (systems that ONAP connects to)
  • Images
  • Networks
  • Infrastructure tenants
  • Relationships
  • Interfaces
  • IP addresses
  • Configurations
  • Licenses
  • Site resources

AAI also provides Inventory History information

4. known system limitations

...

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

Clamp application redundancy HA relies on Kubernetes


5. Used Models

Clamp AAI uses the following models:

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


6. System Deployment Architecture

Clamp consists of 5 containers:

  • CLAMP container
  • MariaDB container
  • Kibana container
  • E_Search container
  • LogStash container

7. New Capabilities in this Release

This release, CLAMP AAI adds the following Capabilities:

...

  • add policy-model to the SDC distributionautomatic rendering of configuration policy UI based on the distributed policy model
  •  better rending of the display of the control loop flow based on the distributed blueprint
  • enhanced internal model to better support model driven approach.
