ABSTRACT:
A network system for effecting signal transmission by connecting node devices with at least plural N channels is disclosed. It includes a first node device constituting at least a node device and having: N fixed-channel reception units for receiving the N channels; N buffers for temporarily storing signals received by the N fixed-channel reception units, wherein a buffer of the N buffers divides the received signals into first signals with designation of a channel for transmission and second signals without designation of a channel for transmission and further divides the first signals in respective designate channels; transmission units for transmitting the first and second signals released from the N buffers in the N channels; an end detection unit for detecting an end of reading of the first and second signals to be transmitted by channels currently capable of transmission; a channel variation control unit for controlling the transmission unit to vary the channels capable of transmitting released signals from the N buffers, in response to a detection of the end of reading by the end detection unit such that the released signals from two or more of the N buffers are not simultaneously supplied to a same channel; and a buffer control unit for controlling the N buffers, in synchronization with a variation of the channels capable of transmitting the released signals from the N buffers, to read the first and second signals be based on the variation of the channels.
