Abstract: Routes of communication data are set in an address area(15) provided in communication data as transmission object by use of root addresses, which are constructed by arranging addresses of relay units(GW1-GW3, H1, RH2) existing at branch points in the communication routes in passing order. The address area(15) is divided into a majority code describing area(17), in which majority codes formed by coding at least types of the relay units(GW1-GW3, H1, RH2) in a discriminable manner are described, and a type code describing area(19), in which type codes formed by coding either the relay units(GW1-GW3, H1, RH2) of the same type or node terminals(N1-N18) as connection objects in a discriminable manner are described.

Abstract: In a communication system wherein a collecting communication unit(1-2) of a plurality of communication units(1-1, ..., 1-n) collects state information from report communication units to manage the state information, each of the report communication units(1-1, 1-3, ..., 1-n) comprises a state information memory(9-1, 9-3, ..., 9-n) for storing the state information of own communication unit, a state monitoring portion(7-1, 7-3, ..., 7-n) for monitoring the state information of own communication unit and then rewriting the stored state information into new state information after change if the state information has been changed, and a transmitting/receiving portion (11-1, 11-3, ..., 11-n)for adding the stored state information and own address to the recovery command and then transmitting the recovery command when respective report communication units(1-1, 1-3, ..., 1-n) receive the recovery command for recovering the state information, whereby the collecting communication unit(1-2) can receive the recovery command to which changed state information and their own addresses of respective report communication units(1-1, 1-3, ..., 1-n) are added collectively.

Abstract: At relay units(GW1, GW2, GW3, RH2), root addresses which are included in packet data and are constructed by aligning addresses of the relay units existing at branch points in communication routes in passing order are decoded, then appropriate routes as a destination of the packet data are selected based on the decoded root addresses and own address stored previously, and then the packet data are transmitted to node terminals designated as the destination via the selected routes, whereby the packet data can be transmitted to a node terminal(N1, ..., N18) as the destination via the designated relay units(GW1, GW2, GW3, RH2).

Abstract: Data compression of digital data, which are sent out sequentially from a connected external device(9) and are divided into blocks, is executed on a time base by executing modulation process in unit of predetermined number of blocks, and the digital data in which header information including at least a destination is allocated to a free time space generated by the data compression are transmitted to a predetermined destination. On the contrary, the header information are extracted from the digital data received from the sender and then erased, and the digital data which are subjected to demodulation process to demodulate a frequency into a transmission speed peculiar to the external device(9) by executing data expansion on the time base are received by the external device(9).

Abstract: The information block that is sequentially extracted from an information sequence and that serves as a conversion unit is divided into a plurality of sub-blocks. Then, counting is performed of the information items number of at least one of "0" and "1" that is contained in each sub-block for each sub-block of a plurality of the thus-divided sub-blocks. Then, there is performed, according to the counted result that has been thus obtained, inversion yes/no determination of whether the original information contained in each sub-block should be inverted under the consideration of minimizing the difference between the number of codes "0", and the number of codes "1", contained in the code block as a whole. Then, there is added, with respect to this sub-block, an inversion identification code that represents the effect that the original information has been inverted or not.

Abstract: When data is exchanged between a pair of LANs (3, 5) via a pair of route hubs (RH4, RH6), one of the route hubs (RH4) sends an address assignment frame to a first LAN (3) in a clockwise direction, assigns an address to each route hub (RH) and each node terminal (N), based on an address value, sequentially from the route hub (RH1) to route hub (RH4), and sends the address assignment frame, which has been returned, to the other route hub (RH6) of the pair. The other route hub (RH6) assigns the address to itself based on the address value contained in the received address assignment frame, sends the address assignment frame to a second LAN (5) in the clockwise direction, assigns the address to each route hub (RH) and each node terminal (N), based on the address value, sequentially from the route hub (RH7), and returns the address assignment frame, which has been returned, to the route hub (RH4). Thus, addresses are automatically assigned to each route hub (RH) and node terminal (N). Upon receiving communication data to be sent to a destination, each of the pair of route hubs (RH4, RH6) selects a route via which the communication data is to be sent, and for sending the communication data to the destination via the selected route.
