    • The present invention provides a communication device, comprising: transmission means for transmitting a plurality of data segments via a packet communication network, each of the data segments including a sequence number, the data segments being transmitted in sequence number order; receiving means for receiving an acknowledgement indicating a data segment which the destination device requests the communication device to transmit next; retransmission means for changing a transmission rate and fro retransmitting one of the data segments in a case that the communication device has not received an acknowledgement including an acknowledgement number greater than a sequence number included in the retransmitted data segment when a predetermined time elapses following transmission of the original data segment; control means for determining a subsequent data segment to be transmitted next, and for controlling a transmission rate on the basis of a category of the acknowledgement and also information included in the acknowledgement.

    • A relay device 40, when it relays data blocks transmitted in succession from a transmitter device 20 to a receiver device 10, is caused to identify a state code showing a state of a communication resource used when the data blocks are transferred. Relay device 40 divides the identified state code into portions of a predetermined data size and writes the divided portions into a predetermined area of the data blocks. Receiver device 10 transmits to transmitter device 20 an acknowledgement containing the same data as is written in a predetermined area of the received data block. Transmitter device 20, upon receipt of the acknowledgement, reads the state code that is divided and written in the acknowledgement and increases or reduces the number of data blocks on the basis of the state code.
    • 当中继装置40将从发送装置20连续发送的数据块中继到接收装置10时,识别表示在传送数据块时使用的通信资源的状态的状态码。 中继装置40将所识别的状态码划分为预定数据大小的部分,并将划分的部分写入数据块的预定区域。 接收机设备10向发射机设备20发送包含写入接收数据块的预定区域中的相同数据的确认。 发送器装置20在接收到确认后,读取在确认中被分割和写入的状态码,并根据状态码增加或减少数据块的数量。
