Abstract
A system and method for prioritizing the delivery of information transfer requests using a least-recently-serviced rotational priority technique in a data processing system having one or more requesters to supply the information transfer requests. Active requesters have currently pending information transfer requests, and non-active requesters have no currently pending information transfer requests. Transfer authorization is granted to an information transfer request associated with an active requester that is currently assigned to the highest priority level in a range of priority levels. Each of the active and non-active requesters that have a priority level less than the priority level of the active requester that was granted the transfer have their priority levels incremented, while the non-active requesters having a priority level greater than the priority level of the active requester that was granted the transfer is maintained at its current priority level. The priority level of the active requester that was granted the transfer is then reassigned to the lowest priority level in the range of priority levels.
