Abstract:
The relay device includes: a frame determination unit that determines a received frame between a high-priority frame and a low-priority frame for each output port on a basis of an identifier; a fixed-delay queue that delays the high-priority frame for a time equal to or longer than the sum of a specified transmission gap and a frame length long enough for a downstream device to be capable of correctly receiving and transferring or discarding a frame, and that transmits the high-priority frame; a low-priority frame storing unit that stores therein the low-priority frame; a transmission-frame selection unit that executes control to discontinue transmission of the low-priority frame when transmitting the high-priority frame, and to retransmit the low-priority frame; and an output control unit that selects a frame to be transmitted to the downstream device on a basis of the control by the transmission-frame selection unit.
