Abstract
A communication device includes: processing circuitry and communication circuitry. The processing circuitry acquires first information related to one or more pieces of content cached in each of relay devices being capable of communicating with a server and are capable of exchanging any of the pieces of content cached therein with one another. The processing circuitry acquires a first content list including an identifier of each of a plurality of pieces of content stored in the server. The processing circuitry specifies, on a basis of the first information, an identifier of a piece of content cached in at least one of the relay devices among the first content list and generates a second content list including the specified identifier and second information indicating that the piece of content identified by the specified identifier is cached in at least one of the relay devices. The communication circuitry transmits the second content list.
