    • In a case where the F-RTO algorithm is simply combined with the exponential backoff algorithm which is being suppressed, there is a problem in that once a spurious timeout occurs, the spurious timeout continuously occurs since then. In order to solve the above problem, according to the present invention, in a communication device for transmitting data segments and receiving acknowledgements in response to the data segments, respectively and sequentially, suppressing an application of a backoff algorithm for increasing a retransmission timeout period at the time of retransmitting a data segment, and controlling the retransmission timeout period to retransmit the data segment, the spurious timeout is determined based upon the acknowledgement received immediately after the retransmission of the data segment. In an event of determining the occurrence of the spurious timeout, the retransmission timeout is increased.
    • 在F-RTO算法简单地与被抑制的指数退避算法组合的情况下,存在一旦出现虚假超时的问题,则从那时起连续发生虚假超时。 为了解决上述问题,根据本发明,在分别依次发送数据段并响应于数据段接收确认的通信装置中,抑制用于增加重发超时时段的退避算法的应用 重传数据段的时间,以及控制重传超时周期以重发数据段,根据在数据段的重传之后立即收到的确认来确定虚假超时。 在确定伪超时的发生的情况下,重传超时增加。
