A communication device, including: a processor configured to estimate each of a plurality of first throughputs for each of a plurality of first route patterns corresponding to each of combinations of a plurality of first routes used in parallel, coupling the communication device to a first content server, estimate each of a plurality of second throughputs for each of a plurality of second route patterns corresponding to each of combinations of a plurality of second routes used in parallel, coupling the communication device to a second content server, select one of the plurality of the first and second route patterns based on the estimated plurality of the first and second throughputs, acquire an identical content from the first content server or the second content server using the selected one of the plurality of the first and second route patterns, and transmit the acquired identical content to a terminal device.
