Abstract
In order to enable a delay until the output of retransmission data to be reduced, performing transfer of a data piece that is input from a data input unit to a first transfer unit, performing determination of necessity of retransmission of the data piece, when the retransmission is determined to be necessary, performing transfer of a retransmission data piece that is necessary to be retransmitted to a second transfer unit, and in advance of at least any of the data piece remaining in the first transfer unit at a point of time of the transfer of the retransmission data piece to the second transfer unit, performing output of the retransmission data piece in the second transfer unit to a same destination as that of the data piece in the first transfer unit.
Claims19
A transmission device comprising:
- a data inputter configured to input a data piece;
- a first transmitter;
- a second transmitter;
- a data transmitter configured to perform transfer of the data piece to the first transmitter;
- a retransmission controller configured to perform determination of necessity of retransmission of the data piece;
- a retransmission data transmitter configured to, when the retransmission is determined to be necessary, perform transfer of a retransmission data piece that is necessary to be retransmitted to the second transmitter;
- and
- an input/output processor configured to, in advance of at least any of the data piece remaining in the first transmitter at a point of time of the transfer of the retransmission data piece to the second transmitter, perform output of the retransmission data piece in the second transmitter to a same destination as that of the data piece in the first transmitter.
A transmission method comprising:
- performing transfer of a data piece that is input from a data inputter to a first transmitter;
- performing determination of necessity of retransmission of the data piece;
- when the retransmission is determined to be necessary, performing transfer of a retransmission data piece that is necessary to be retransmitted to a second transmitter;
- and
- in advance of at least any of the data piece remaining in the first transmitter at a point of time of the transfer of the retransmission data piece to the second transmitter, performing output of the retransmission data piece in the second transmitter to a same destination as that of the data piece in the first transmitter.
17-30. (canceled)
A computer readable recording medium recorded with a transmission program causing a computer to execute:
- a data transmission function of performing transfer of a data piece that is input from a data inputter to a first transmitter;
- a retransmission control function of performing determination of necessity of retransmission of the data piece;
- a retransmission data transmission function of, when the retransmission is determined to be necessary, performing transfer of a retransmission data piece that is necessary to be retransmitted to a second transmitter;
- and
- an input/output processing function of, in advance of at least any of the data piece remaining in the first transmitter at a point of time of the transfer of the retransmission data piece to the second transmitter, performing output of the retransmission data piece in the second transmitter to a same destination as that of the data piece in the first transmitter.
