[PROBLEMS] To realize a scalable, highly reliable, and low-delay multicas t at a low cost. [MEANS FOR SOLVING PROBLEMS] Provided is a network system i ncluding M terminals each connected to a network. Each of the terminals incl udes: storage means which stores the M terminals including the one terminal while correlating them to N (N < M) groups; reception means for receiving first information from another terminal; group selection means for selectin g a group of the transmission destination of the second information from the N groups according to the group correlated to the another terminal; termina l selection means for selecting a terminal of the transmission destination o f the second information from the terminals correlated to the selected group ; and transmission means for transmitting the second information to the sele cted terminal.
