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.
