<p>PURPOSE:To realize the simplifying of the constitution of an information communication network as a whole, securing an advantage that high speed communication is enabled by applying a master slave constitution also in the information communication network of a conventional token passing system. CONSTITUTION:At a point of time when the token of an address 3 appears on a transmission line, a transmission right is imparted to a slave node, and the slave node transmits its own data and does not transmit the token. Because the node does not have a transfer function, it is not capable of performing a transmission. On behalf of it, a master node transmits the token of an address number '0'. By operating in such a way, the signal on the transmission line looks as if the aggregation of communication nodes had performed communication. Because the slave node needs the only acquisition function of four functions of the acquisition function, the transfer function, the reproduction function at the time of a dissipation and the generation function at the time of a start that the normal node has, the part corresponding to the replacement of the slave node can be simplified.</p> |
