Claim:
1. A transmission device comprising: an interface unit connected to a client device compatible with a relatively low communication rate; a frame processing unit that is compatible with a relatively high communication rate and processes a frame transmitted from the client device; and a routing unit that routes a frame between the interface unit and the frame processing unit, wherein the interface unit receives a pause frame received from the client device, the pause frame including a first quanta value representing a pause interval in the relatively low communication rate, the routing unit generates one or a plurality of pause frames in accordance with a pause time designated by one pause frame received by the interface unit, the one or plurality of pause frames corresponding to a second quanta value, the second quanta value being obtained by converting the first quanta value according to a difference between the relatively low communication rate and the relatively high communication rate, and transmits the one or plurality of generated pause frames to the frame processing unit, and the frame processing unit stops transmitting frames to the client device in accordance with the one or plurality of pause frames transmitted from the routing unit.
