Disclosed is a network system for connecting a plurality of node devices by a plurality of parallel transmission channels and connecting terminals to respective ones of the plurality of transmission channels via the node devices. Each node device temporarily stores output packets by allotting the packets to a plurality of storage areas that correspond to respective ones of the plurality of transmission channels. When a stored packet is transmitted by selecting any one of the plurality of transmission channels, control is performed so as to read out the packet that has been stored in the storage area that corresponds to the selected transmission channel. In a case where a stored packet to be transmitted over the plurality of transmission channels is a packet for broadcast, the packet is duplicated by being distributed to the plurality of storage areas that correspond to the plurality of transmission channels that are to transmit the packet.
