FIG8 is a diagram illustrating another example of BC order determination according to the embodiment. As depicted in FIG8, for a plurality of BCs targeted of the transaction, that is, BC-A and BC-B, respective BC information is stored in the BC information table 261. For BC-A, the TX queue size 261b is 2 MB. The block size 261c is 1 MB. For BC-B, the TX queue size 261b is 50 MB. The block size 261c is 10 MB.
