Abstract
An information transmission device stores an identifier representing an information processing device connected to a network in association with an identifier representing a storage device used by the information processing device. When transmission of information is requested from the information processing device, the information transmission device specifies an identifier representing an information processing device. The information transmission device acquires an identifier representing a storage device stored in association with the specified identifier. The information transmission device transmits information on a request for transmission by the information processing device to the storage device represented by the acquired identifier.
