<p>The purpose of the present invention is to provide a relay device, etc., whereby it is possible to efficiently transfer packets while maintaining fault tolerance in a content distribution service, etc., using IP multicasting. FEC identification information is extracted from a first packet header, a parameter is derived on the basis of the extracted FEC identification information, a second code is generated on the basis of the derived parameter, a second packet is generated on the basis of the first packet and the second code, and the second packet is transmitted.</p> |
