Abstract
A method of transmitting data ( ) generated in an upper layer protocol such as iSCSI in a transport protocol such as TCP or SCTP, without requiring separate reads for check code generation and transmission. The upper layer protocol data is read into a transmission engine ( ) that calculates the error check codes and inserts them into the transport protocol transmission. To prevent having to recalculate error codes in the event of loss of transmitted data and a retransmission request, the engine preferably also writes the error check codes into the memory so that the can be retrieved if retransmission is necessary.
