Abstract
The present invention provides for a method of transferring information in a network computing system environment. The network environment includes a main storage coupled to a channel subsystem with a plurality of channels which is in processing communication with a control unit capable of coupling to a plurality of input/output devices. At first the packets of data are sent concurrently to and from the main storage. Next execution of certain channel functions are transferred to the control unit so that certain commands can be combined with the data packets in one sequence. Finally only one start data command and only one end command notification needs to be sent before and after a plurality of data packets is transferred respectively. In one embodiment another method is employed in the same network computing system environment having the steps of: fetching said command from said main storage; fetching associated data from said main storage; and transferring said fetched command along with said fetched associated data to said control unit.
