摘要：A data communication method is provided to divide high-capacity data into plural block data, so as to transmit the divided block data clearly to plural clients from a server through multicast communication. A server(1) allocates representative clients for each of plural block data. The server transmits block data and information indicative of the allocated representative clients to clients through multicast communication. The representative clients transmit response confirm messages to the server. If the server receives the response confirm messages, the server transmits succeeding block data of the block data and information indicative of newly allocated representative clients to the clients through the multicast communication.
