<p>PROBLEM TO BE SOLVED: To execute the load balancing processing of a plurality of channels without affecting transfer throughput by setting a using ratio corresponding to the loads of respective communication channels, switching the plurality of communication channels corresponding to the loads and sending out packets. SOLUTION: A transfer value up to the present time is stored in counters 13 and 14 corresponding to channel correspondence parts 11 and 12. Also, a ratio register 17 indicates the value of a set value 50:50 for instance. In the state, in a comparator 16, the values of the counter 13 and the counter 14 are compared under the weight of 50:50 and the smaller counter 14, for instance, is selected. Further a selector 15 is instructed to select the channel correspondence part 12. The selected channel correspondence part 12 outputs first data in a data memory 18 onto the channel. Thereafter, the transfer data length is added to the counter 14. In such a manner, the plurality of communication channels are switched corresponding to the loads of the respective communication channels and the packets are sent out.</p> |
