Abstract
The present invention aims at making the cut-through trigger variable in accordance with the traffic environment, thereby increasing the cut-through traffic to enhance the efficiency of communication. In the trigger filtering unit (16A), the number of transfers of the hop-by-hop packet meeting each of a plurality of preset trigger conditions is counted. In the processor (15A), the rate of the traffic meeting each of trigger conditions to all the traffics of the hop-by-hop transfer is calculated in accordance with the count value, a trigger condition under which the rate exceeds the threshold value is selected as the cut-through trigger, and it is determined which of the cut-through transfer mode and the hop-by-hop transfer mode should be selected.
