Abstract
A transfer apparatus has an input port and an output port, an input line speed of the input port and an output line speed of the output port being capable of being set to differ from each other. The transfer apparatus comprises, for each output port: a low-latency frame transmission buffer to store a low-latency frame received at the input port; a normal-latency frame transmission buffer to store a normal-latency frame that is a frame received at the input port, the normal-latency frame being permitted to be transferred with higher latency than the low-latency frame; a time calculation unit to calculate output start time of the low-latency frame by using information on a frame length of the low-latency frame, the input line speed, and the output line speed when the low-latency frame is received; and an output contention control unit to control transfer of the low-latency frame and the normal-latency frame by using the output start time.
