ABSTRACT:
A network system includes a plurality of nodes each connecting a first adjacent node and a second adjacent node. In each node, a control signal is received by the receiver from the first adjacent node. A control signal analysis processor analyzes the control signal to perform a activity according to the control signal, and at the same time, an intermediate node determination processor stores the control signal so as to pass the control signal through the node when the control signal is destined for another node. A selector selects a single output signal from the control signal and an output signal of the control signal analysis processor such that the control signal is selected when the control signal is destined for another node. The selected signal is transmitted by a transmitter toward the second adjacent.
