Abstract: PROBLEM TO BE SOLVED: To speed up valid link transfer speed when the link frame of data is communication between a system emitting a command and a system receiving the command by automatically controlling the reading or writing of multiple storage blocks distributed in the storage area of the command reception system. SOLUTION: A connection mechanism (CF) is the system receiving the command at one end of a link and a center processing complex(CPC) is the system emitting the command at the other end of the link and it requests the operation of the writing or reading of the structure of CF. An inter CF system channel contains a data mover 1006 connected to a memory 1002 and a processor 1004. A TRANSFER STRUCTURE (TS) instruction is executed only in the system receiving the command in response to CF receiving the SEND MESSAGE command and structure is transferred between CPC and CF through the link 910 in any link direction.
