Zusammenfassung:The subject of the present invention in general pertains to a new Input-Output facility design that exploits high bandwidth integrated network adapters. A computer program product in a network environment having a main storage in processing communication with an interface element having adapters for storing data in a queuing mechanism in the main storage. The program product comprises a data storage device including a computer usable medium having computer readable program means for ensuring proper and timely processing of data and computer readable code means for providing a plurality of queue sets; for dedicating one or more queues in each set as input or output queues; for providing the ability to said queues to share access to a plurality of devices in said network across a plurality of communication stacks; for mapping various resources to said queues to facilitate resource allocation and dynamic configuration by providing initialization of a plurality of configuration parameters; and for providing dynamic expanding and contracting of the number of queues in each set as dictated by traffic patterns and feedback indicators.
