Abstract:
A communication system comprising:a plurality of repeating devices each having one or more node terminals connected thereto, said repeating devices being connected with each other through a data transmitting path, whereby end-to-end data communication is carried out between said node terminals, between said repeating devices, and between said node terminals and said repeating devices, said repeating devices each comprising: node terminal address storage configured to store node terminal addresses established to inherent values for said node terminals, respectively; repeating device address storage configured to store a repeating device address established to an inherent value for said repeating device concerned and established to be distinguishable from said node terminal addresses; and a header information adder configured to add sender/destination information that identifies a sender node terminal or a sender repeating device, or a destination node terminal or a destination repeating device, to communication data which has been fed from said repeating device concerned or said one or more node terminals connected thereto, and to send said communication data with said sender/destination information toward said data transmitting path; wherein said sender/destination information includes either one of a node terminal address stored in said node terminal address storage, and a repeating device address stored in said repeating device address storage.
