| 摘要 | Provided is a data communication apparatus which includes a transmission interval calculator configured to calculate an effective transfer speed of the data based on a difference between an actual arrival time at which response data to transmission data transmitted to the other data communication apparatus has arrived and a predictive arrival time calculated by multiplying the number of relay devices passed until the response data from the other data communication apparatus arrives at the data communication apparatus by a transfer delay time necessary to pass through one relay device and a buffer size of the relay device on a communication path of the data, and calculate a transmission interval of transmission data based on the effective transfer speed and a transmission controller configured to perform transmission control of transmission data based on the transmission interval. Thus, congestion control is efficiently implemented in an interconnection network configured as a regular network. | ||

| 主权项 | 1. A data communication apparatus configured to transmit data to another data communication apparatus through a relay device, comprising: a transmission interval calculator configured to calculate an effective transfer speed of the data based on a difference between an actual arrival time at which response data to transmission data transmitted to the other data communication apparatus has arrived and a predictive arrival time calculated by multiplying the number of relay devices passed until the response data transmitted from the other data communication apparatus arrives at the data communication apparatus by a transfer delay time necessary to pass through one relay device and a buffer size of the relay device on a communication path of the data, and calculate a transmission interval of transmission data by subtracting a value obtained by dividing a data length of the data by a non-congestion transfer speed at which congestion does not occur from a value obtained by dividing the data length by the effective transfer speed; and a transmission controller configured to perform transmission control of transmission data based on the calculated transmission interval. | ||
