<p>PROBLEM TO BE SOLVED: To simultaneously solve both problems of transmission time to be a problem in the case that a packet size is large and transmission efficiency to be a problem in the case that the packet size is small and further to freely set the compromising point of the transmission time and the transmission efficiency different depending on the kind of data to be transmitted by arbitrarily setting a threshold. SOLUTION: A comparison part 3 respectively receives the packet size of a packet from a size information obtaining part 2 and a predetermined threshold from a threshold storage part 4, connects a changeover switch 5 to a terminal A at the time of the packet size >= the threshold and connects the changeover switch 5 to a terminal B at the time of the packet size <= the threshold. As a result, at the time of the packet size > the threshold, the packet is divided in a packet division part 6 and then, distributed to plural transmission circuits 8. Also, at the time of the packet size <= the threshold, the packet is distributed to the plural transmission circuits 8 for the respective packets without being divided.</p> |
