Abstract
A transfer device includes: a determination unit configured to determine, if a data packet including content and list information is received as a response to a transferred request packet, whether or not the content can be transmitted to a transfer device that has transmitted the request packet, based on an identifier of the transfer device that has transmitted the request packet and the list information. The list information included in the data packet is generated based on an identifier of a transfer device to which the content included in the data packet can be transmitted, of a plurality of transfer devices in the content distribution system, or is generated based on an identifier of a transfer device to which the content included in the data packet cannot be transmitted.
