Control apparatus, data transmitting system, and method of data transmitting

A data transmitting system comprising:

• a plurality of data transfer apparatus including a first data transfer apparatus including a first port;
• a data buffer;
• and
• a control apparatus including a memory and a processor coupled to the memory and configured to:
• detect that a first transmission rate of first data transmitted using the first port of the first data transfer apparatus is equal to or higher than a first value,
• request, when it is detected that the first transmission rate is equal to or higher than the first value, a second data transfer apparatus included in the plurality of data transfer apparatus to change a destination of a first packet from a first information processing apparatus to the data buffer, the first packet being to be transmitted using the first port,
• cause, after the first packet transmitted from the second data transfer apparatus is stored in the data buffer for a first period, the data buffer to transmit the first packet to the first data transfer apparatus, and
• request the second data transfer apparatus to change the destination of the first packet from the data buffer to the first information processing apparatus, the first packet being transmitted from the data buffer to the second data transfer apparatus.

A method of data transmitting using a first data transfer apparatus including a first port, a data buffer and a control apparatus, the method comprising:

• detecting, by the control apparatus, that a first transmission rate of first data transmitted using the first port of the first data transfer apparatus is equal to or higher than a first value;
• requesting, by the control apparatus, when it is detected that the first transmission rate is equal to or higher than the first value, a second data transfer apparatus to change a destination of a first packet from a first information processing apparatus to the data buffer, the first packet being to be transmitted using the first port;
• changing, by the second data transfer apparatus, the destination of the first packet from the first information processing apparatus to the data buffer;
• transmitting, by the second data transfer apparatus, the first packet to the data buffer;
• storing the first packet in the data buffer for a first period;
• causing, by the control apparatus, after the first packet is stored in the data buffer for the first period, the data buffer to transmit the first packet to the second data transfer apparatus;
• requesting the second data transfer apparatus to change the destination of the first packet from the data buffer to the first information processing apparatus, the first packet being transmitted from the data buffer to the second data transfer apparatus;
• changing, by the second data transfer apparatus, the destination of the first packet from the data buffer to the first information processing apparatus;
• and
• transmitting, by the second data transfer apparatus, the first packet to the first information processing apparatus.
