Control method for transmission and reception system, transmitting apparatus, and receiving apparatus

A transmitting apparatus comprising:

• a memory;
• and
• a processor coupled to the memory,
• the transmitting apparatus is coupled to an information processing apparatus, which transmits a plurality of command groups each including a plurality of commands to an input and output apparatus, and is coupled to a receiving apparatus, which is coupled to the input and output apparatus, through a network,
• the processor is configured to:
• receive a first command group including a plurality of commands from the information processing apparatus;
• transmit a leading command of the plurality of commands in the first command group to the receiving apparatus;
• transmit a first response to the information processing apparatus in response to the leading command received from the information processing apparatus;
• receive a second response from the receiving apparatus in response to the leading command;
• obtain a second command group including a plurality of commands from the information processing apparatus after receiving the second response;
• and
• batch-transfer the plurality of commands in the first command group and the plurality of commands in the second command group to the receiving apparatus without making a third response for each of the plurality of commands in the first command group and the plurality of commands in the second command group to the information processing apparatus.

A receiving apparatus comprising:

• a memory;
• and
• a processor coupled to the memory,
• the receiving apparatus is coupled to an input and output apparatus and is coupled to a transmitting apparatus coupled to an information processing apparatus, which transmits a plurality of command groups each including a plurality of commands to the input and output apparatus, through a network,
• the processor is configured to:
• receive a leading command of a plurality of commands in a first command group, which is transmitted from the information processing apparatus, from the transmitting apparatus which transmits a first response to the information processing apparatus in response to the leading command;
• transmit a second response to the transmitting apparatus in response to the leading command;
• receive the plurality of commands in the first command group and a plurality of commands in a second command group which are batch-transferred from the transmitting apparatus, the second command group being transmitted from the information processing apparatus to the transmitting apparatus without making a third response for each of the plurality of commands in the first command group and the plurality of commands in the second command group to the information processing apparatus after the second response is received in the transmitting apparatus;
• issue the plurality of commands in the first command group and a plurality of commands in a second command group from the transmitting apparatus to the input and output apparatus;
• and
• notify, in a case where the plurality of commands in the first command group and the plurality of commands in the second command group are batch-transferred from the transmitting apparatus, the transmitting apparatus about processing completion when processing of all of the plurality of commands in the first command group and the plurality of commands in the second command group is completed.
