The clamp functional entity provides the capability to manage runtime control loops. It provides the capaiblity to
- configure DCAE applications of the control loop
- Associate policies to the DCAE application
- Configure the oprations to be taken by the cotnrol loop (by creating/updating/deleting operational policies)
- Deploy/un-deploy control loop flow (blueprints) to DCAE
- Control loop visulization.
Clamp Relise on Policy to communite to App-C/VF-C/SDN-C/SO in runtime, hence these are not part of CLAMP
2. CLAMP API definitions
CLAMP provides multi-cloud function provides mediation capabilities to connect to different infrastructure providers.
- Adapt ONAP to VM based infrastructure such as openstack,Azure
- Adapt ONAP to Container Orchestration Engine, such as K8S
- Discovery and registration of resource information.
- Relay FCAPS data from infrastructure to DCAE
2. MultiCloud API definitions
Multi-Cloud provides the following interfaces:
| Interface Name | Interface Definition | Interface Capabilities | ||||
|---|---|---|---|---|---|---|
| CLAMPEMCE-12 | Control Loop Resource Lifecycle Management Interface . | A user interface for:
| CLAMPE-2 | Control loop dashboard. User interface to show the status of the control loop | Provides a course grain VNF level LCM interface in a template driven and cloud agnostic way | Provides:
|
| MCE-3 | N/A Place holder for SDN interconnect interface | Envisaged Future Capability | ||||
| MCE-4 | Atomic Resource LCM Provides a fine graned resource LCM interface at the VM level. This is an atomic resource level workload LCM (specific to openstack resources) | Provides:
