    • A communication apparatus for transmitting data to a data accumulation apparatus via a relay apparatus detects, by communication with the relay apparatus, which is the relay function used by the relay apparatus to operate, a proxy relay function of temporarily holding and proxy-transmitting the data and a transparent relay function of transparently transmitting the data without holding. The communication apparatus transmits the data based on the detected relay function. When the data is being transmitted using the relay apparatus operating by the transparent relay function, and a disconnection notification representing disconnection of communication between the relay apparatus and the data accumulation apparatus is received from the relay apparatus, the data transmission is immediately stopped. When the data is being transmitted using the relay apparatus operating by the proxy relay function, the data transmission is continued.
    • 经由中继装置向数据存储装置发送数据的通信装置通过与作为中继装置所使用的中继功能进行动作的中继装置进行通信,检测临时保存和代理发送数据的代理中继功能 以及透明的中继功能,可以透明地传输数据而不进行保持。 通信装置基于检测到的中继功能发送数据。 当使用通过透明中继功能操作的中继装置发送数据时,从中继装置接收到表示中继装置与数据存储装置之间的通信断开的断开通知,立即停止数据发送。 当使用由代理中继功能操作的中继装置发送数据时,继续进行数据发送。
