Abstract
A computer program product for performing input/output (I/O) processing is configured for performing a method including: obtaining information relating to an I/O operation at a channel subsystem; generating and storing in local channel memory at least one address control word (ACW) specifying one or more host memory locations for data transfer and including a field for storing header information; generating an address control structure specifying a location in the local channel memory of a corresponding ACW; receiving a data transfer request from a network interface that includes the address control structure; responsive to an input data request, routing the data to at least one host memory location specified by the corresponding ACW and storing header information in the corresponding ACW; and responsive to an output data request, routing the data from a host memory location specified by the ACW to the network interface and appending header information to the data.
