    摘要： In a system which includes a plurality of subsystems (11-14), and a transmission medium (1) for coupling them, and in which a token (301) is sent to the transmission medium, whereby the transmission medium is occupied; a transmission control method is characterized, at least, in that each of the certain subsystems appends a code (FC) indicative of a function of certain data to the data and sends the resulting data to the medium, and that the subsystem receiving the data refers to the code indicative of the function of the data, thereby to independently judge whether or not the data is to be accepted into the own subsystem.

    摘要： A distributed processing system comprises a plurality of pro­cessors (11 to 14) which are connected to a common trans­mission line (1). When a program constitution in anyone of the processors (11 to 14) has changed, a message to this effect is broadcast to the common transmission line (1). When the mess­age has been received from the common transmission line (1), information on programs stored in the respective processor (11 to 14) is broadcast to the common transmission line (1), whereby the messages indicating the program constitutions in the individual processors (11 to 14) are automatically broad­cast onto the transmission line (1) at the changes of the con­stitutions of programs. If in such a system a series of pro­cesses are executed by a plurality of programs, the relation among programs according to the flow of the series of pro­cesses can be recognized using information on the input/output data of each of the programs.

    摘要： According to the present invention, a file recovery system is provided in which the commands for recovering files such as a historical file are unnecessitated and the recovery system configuration is independent of the host processing system. That is, since the equipment (12) for achieving a file recovery does not have an information about the location of the recovery data, an information about the content of a file to be recovered is transmitted to a transmission line (1). The other equipments (12) asynchronously receive the information and judges whether or not a file containing the same file exists in the own system. If the file exists, the content of the file is transmitted to the transmission line (1). The equipment (12) achieving the file recovery asynchronously receives from the transmission line (1) the file data of files such as a historical file and establishes data consistency by use of the buffered current data (504) and the event number (1004), thereby recovering files such as a historical file.
