A node device for performing packet communication using a transmission line composed of a plurality of channels is connectable to a network having a plurality of node devices, each of the plurality of node devices connecting the transmission line to a sub-transmission line. The node device a has packet processor for processing a packet, first, second, and third devices for outputting a packet, a memory device and a transmitter. The first device corresponds to each of the plurality of channels and outputs a packet input on a predetermined one of the plurality of channels to a side of the sub-transmission line or a side of the transmission line. The second device corresponds to each of the plurality of channels and outputs a packet transmitted through the sub-transmission line to the transmission line side or the packet processor side. The third device outputs a packet supplied thereto from the packet processor to the sub-transmission line side. The memory device corresponds to each of first and second devices, and temporarily stores a packet output from each of the first and second devices. The transmitter transmits outputs from the memory device in channels different from each other.
