A root node creates and issues an object ID comprising share information designating a share unit, which is a logical public unit. The share unit is a logical public unit comprising no less than two objects. Transfer control information in which share information is associated with device information showing a device for managing this share unit, is prepared for each share unit. The root node receives request data, which has an object ID comprising share information, specifies device information corresponding to the share information in this object ID from the transfer control information, and transfers the request data to the device indicated in this device information.
