Abstract
In a network system, a loop-shaped transmission path is constituted by multiplexing a plurality of loop-shaped transmission channels. A plurality of nodes are connected to the loop-shaped transmission path. Each of the plurality of nodes can access at least two channels of the plurality of channels multiplexed in the loop-shaped transmission path. Each of plurality of nodes has a loop-shaped transmission route which is formed via a plurality of channels and which does not exceed one round of the loop-shaped transmission path.
