    • There is provided a data relay apparatus and a data relay method which prevent data units from being sent out to a communication network in a burst-like manner by the order assurance function, in consideration of the type of data unit. A type determination section 305 of a data relay apparatus 300 determines the type of a received data unit. An order determination section 304 determines whether or not the arrival order of the received data unit is correct. If it is determined that the arrival order of Ack is not correct, based on the determination results by the order determination section 304 and the type determination section 305, an order assurance function control section 303 disables the order assurance function for the Ack and immediately transmits it.
    • 提供了数据中继装置和数据中继方法,该数据中继装置和数据中继方法考虑到数据单元的类型,通过订单保证功能,防止数据单元以突发状态发送到通信网络。 数据中继装置300的类型确定部分305确定接收数据单元的类型。 订单确定部304判定接收数据单元的到达顺序是否正确。 如果确定Ack的到达顺序不正确,则根据订单确定部分304和类型确定部分305的确定结果,订单保证功能控制部分303禁止Ack的订单保证功能并立即发送 它。

    • A first loss determination section 13 of a first communication device 10 determines that a data unit is lost if an acknowledgment response for the transmitted data unit from a second communication device 30 is not received within a predetermined time and retransmits the data unit when the determination is made. When a determination section 16 determines that a spurious timeout has occurred, a window control section 17 sets a target value for decreasing the size of a congestion window and then gradually decreases the size of the congestion window to the target value when the acknowledgment response is received. Therefore, in a case of executing a response algorithm for changing a slow start threshold and the congestion window, if a segment loss occurs subsequent to the spurious timeout, an efficient loss recovery is achieved and the throughput is improved.
    • 如果在预定时间内没有接收到来自第二通信设备30的发送数据单元的确认响应,则第一通信设备10的第一丢失确定部分13确定数据单元丢失,并且当确定是 制作。 当确定部分16确定发生了虚假超时时,窗口控制部分17设置用于减小拥塞窗口大小的目标值,然后当收到确认响应时,将拥塞窗口的大小逐渐减小到目标值 。 因此,在执行用于改变慢启动阈值和拥塞窗口的响应算法的情况下,如果在虚假超时之后发生段损耗,则实现有效的丢失恢复,并且提高吞吐量。
