Abstract
In a data communication method, when packet data are sent and received among a plurality of computers connected each other via the network, communications are established by using a unicast connection. Then, the packet data are sent by selectively using a multicast communication and the unicast communication for at least one computer to which the communication is established. As a result, it is possible to reduce an amount of network traffic under a peer-to-peer network without intermediation of a server and improve reliability of the multicast communication.
