-
- Capacity Management Scenario
-
-:numref:`figure5` shows a detailed message flow between the consumers and the
-functional blocks inside the VIM and has the following steps:
-
-Step 1: The consumer subscribes to capacity change notifications
-
-Step 2: The Capacity Manager monitors the capacity information for the various
-types of resources by querying the various Controllers (e.g. Nova, Neutron,
-Cinder), either periodically or on demand and updates capacity information in
-the Capacity Map
-
-Step 3: Capacity changes are notified to the consumer
-
-Step 4: The consumer queries the Capacity Manager to retrieve capacity detailed
-information

-
- Resource Reservation for Future Use Scenario
-
-:numref:`figure6` shows a detailed message flow between the consumers and
-the functional blocks inside the VIM and has the following steps:
-
-Step 1: The consumer creates a resource reservation request for future use by
-setting a start and end time for the allocation
-
-Step 2: The consumer gets an immediate reply with a reservation status message
-"reservationStatus" and an identifier to be used with this reservation instance
-"reservationID"
-
-Step 3: The consumer subscribes to reservation notification events
-
-Step 4: The Resource Reservation Manager checks the feasibility of the
-reservation request by consulting the Capacity Manager
-
-Step 5: The Resource Reservation Manager reserves the resources and stores the
-list of reservations IDs generated by the Controllers (e.g. Nova, Neutron,
-Cinder) in the Reservation Map
-
-Step 6: Once the reservation process is completed, the VIM sends a notification
-message to the consumer with information on the reserved resources
-
-Step 7: When start time arrives, the consumer creates a resource allocation
-request.
-
-Step 8: The consumer gets an immediate reply with an allocation status message
-"allocationStatus".
-
-Step 9: The consumer subscribes to allocation notification events
-
-Step 10: The Resource Allocation Manager allocates the reserved resources. If
-not all reserved resources are allocated before expiry, the reserved resources
-are released and a notification is sent to the consumer
-
-Step 11: Once the allocation process is completed, the VIM sends a notification
-message to the consumer with information on the allocated resources
