Abstract
A method of transferring data in a network computing environment having a controlling program and a main storage in processing communication with an interface element including one or more adapters. A queuing mechanism is first established in the main storage for asynchronous transmittal of data between the program and said interface element. At least one queue-set is dedicated to input data and another queue-set to output data in the queuing mechanism. Queuing priorities both for said input and output queue-sets are then determined according to importance of data to be processed or transferred or other internal dependencies and a queue-description record is established by passing a QDIO queue command. From this the priority and number of the output queue are provided by order in which the order specified in the queue descriptor record relative to any other output queues described in that record. Data is then transferred and received according to the queuing priority by interrogating multiple queues in the mechanism simultaneously and determining appropriate location to which data has to be stored to or transferred from.
