PURPOSE:To achieve traffic control in a loop, by each terminal device which compares the figure of itself with figures of other devices, through added figure representing the length of transmission queue matrix to a transmission frame. CONSTITUTION:In transmitting data in a loop, when a transmission frame from other terminal devices is received, a figure NR representing length of queue matrix added to the transmission frame is detected. When the figure NR is greater than a figure NS representing the length of queue matrix added to the transmission frame by the terminal device of itself, the transmission frame from other received terminal device is taken for priority. When the NS is greater than the NR, the transmission frame of the terminal device of itself is made before, and the transmission frame of other terminal devices received succeedingly is transmitted. |
