摘要： A control apparatus includes a memory and a processor. The processor sets a comparison reference value on the basis of a first response time of a response to a first command that has been issued to a transmission destination. The processor stores the comparison reference value in the memory. The processor compares, when a second command is to be issued, a differential amount of data flows with the comparison reference value stored in the memory. The differential amount indicates a difference between an amount of data flows related to commands that have been issued to the transmission destination and an amount of data flows related to response data that have been received from the transmission destination. The processor restrains, when the differential amount exceeds the comparison reference value, the second command from being issued.
摘要翻译：控制装置包括存储器和处理器。处理器基于对已经发送到发送目的地的第一命令的响应的第一响应时间来设置比较参考值。处理器将比较参考值存储在存储器中。当要发出第二命令时，处理器比较存储有比较参考值的差分数据量。差分量表示与发送到发送目的地的命令相关的数据流量与从发送目的地接收到的响应数据相关的数据流量的差。当差分量超过比较参考值时，处理器抑制第二个命令被发出。
