摘要:
A message processing system has a common transmission medium and a plurality of processors or processing equipments connected to the common transmission medium. The processors process messages independenty from each other. Each processor adds information relating to an order of messages to a message resulting from processing by the processor and sends to resulting message to the common transmission medium. In accordance with the invention, a plurality of messages are readily identified.

A file editing method and a system therefor is used in a file editing system for sequentially connecting the files, which are stored in memory devices of a plurality of distributed devices connected to a common signal transmission line, to an edition data flowing on the common signal transmission line. Each of the devices sends a structuring message having the combination and order of the files to be connected to the common signal transmission line; judges whether or not its own file is contained in files to be edited on the basis of the structuring message and its own connection information when it receives the structuring message; sends a response message having the information of the file to the common signal transmission line if its own file is contained; and structures a connection information required for the file edition in itself on the basis of the structuring message in case it is confirmed through the message that all the files to be edited exist in the system. As a result, the file edition for editing a desired combination of files can be structured even if the whole structure of the files of the system is unknown, and the file edition can be structured by contracting or expanding devices even if the structure of the files fluctuates.
摘要:
In a method for checking consistency of distributed data in which data distributedly stored in a plurality of devices connected to a common data transmission line are sequentially combined, each device sends out to the data transmission line output data accompanied with information indicating a position of a processed result in the output data, and the device which receives redundant data compares collected redundant data to select a correct data by comparing only the portion of the data which was lastly added in accordance with the information accompanying the data.
