Abstract
A method of performing an input/output (I/O) processing operation includes: generating an address control structure for each of a plurality of consecutive data transfer requests, each address control structure specifying a local channel memory location of a corresponding address control word (ACW); receiving a data transfer request from a network interface that includes addressing information specified by a corresponding address control structure; comparing, by a data router in the channel, an Offset field of an address control structure and an Expected Offset field of an ACW to determine whether the data transfer request has been received in the correct order; and based on determining that the data transfer request has been received in the correct order, accessing the ACW by the data router and routing the data transfer request to a host memory location specified in the ACW.
