Abstract
A queuing method and apparatus for receipt and transfer of incoming and outgoing data inn a network environment having a main storage. The mechanism includes at least one set of dedicated input queues and at least another set of dedicated output queues. In addition a plurality of queuing components is also provided that include attributes of devices to and from which data is to be transferred or received, and information about the queuing mechanism itself. The input and output queues also comprise an information block containing address of all input and output queues, a storage information block providing information about the queuing mechanism and storage list information blocks that defined for each queue containing specific information about that queue itself. In addition, the input and output queue sets include storage lists for identifying any input-output buffer(s) associated with each queue-set and a storage block address list for providing information about storage locations of any input-output buffer.
