Distributed computer system and method using a common transmission line in a plurality of processors interconneted for executing a program module utilizing attributes

An information management method in a distributed computer system comprising a plurality of processors including program modules and a common transmission medium for connecting between said plurality of processors and which can send information via said common transmission medium, the method comprising:

• a step of recognizing a quality of information to be sent from a program module in a first processor to said common transmission medium among a predetermined plurality of kinds of information including at least one of generation frequency, data length, use of said information, and property of application of the distributed computer system;
• a step of adding an information attribute identifier corresponding to the recognized quality of information to be sent and sending it to said common transmission medium;
• a first decision step of deciding by a second processor whether said information sent to said common transmission medium is information that can be received by a program module in the second processor;
• a step of selectively reading said information from said common transmission medium on the basis of the decision result;
• a second decision step of deciding whether said received information is information which is to be received by a program module in the second processor, on the basis of said information attribute identifier attached to the read information;
• a step of supplying the received information to said program module when said decision result shows that it is receivable;
• and
• a step of abolishing the received information when said decision result shows that it is not receivable.

An information management method in a distributed computer system comprising a plurality of processors including program modules and a common transmission medium for connecting between said plurality of processors and can send information via said common transmission medium, comprising:

• a step of measuring data receiving/sending time and data length, and calculating an average interval time and average data length of an information to be sent from a program module in a first processor;
• a step of recognizing a quality of said information to be sent from said program module, based upon the calculated average interval time and average data length, said quality being among a predetermined plurality of kinds of information including at least one of generation frequency, data length, use of said information, and property of application of the distributed computer system;
• a step of adding an information attribute identifier corresponding to the recognized quality of information to be sent and sending it to said common transmission medium;
• a first decision step of deciding by a second processor whether said information sent to said common transmission medium is information that can be received by a program module in the second processor;
• a step of selectively reading said information from said common transmission medium on the basis of the decision result;
• a second decision step of deciding whether said received information is information which is to be received by the program module in the second processor on the basis of said information attribute identifier attached to the read information, according to a management information in which said information attribute identifier corresponding to the quality of information permitting the information to be received by the program module is registered, based upon an operation status of the receiving processor;
• a step of supplying the received information to said program module when said decision result shows that it is receivable;
• and
• a step of abolishing the received information when said decision result shows that it is not receivable.
