MULTICAST LIMITING/DISTRIBUTING METHOD, ITS DEVICE AND MEDIUM RECORDING ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To distribute data by limiting a reception computer by a transmission computer side and to suppress a communication overhead to be minimum. SOLUTION: The destination computer limiting transmission means 11 of a transmission computer 10 transmit an identifier list, where the identifiers of the computer being the object of reception are made into the list as a destination list or data is added to the destination list and it is transmitted to the reception computer 20. When data of the same object of reception exists, only the data is transmitted. When the self-identifier is included in the received destination list, the data fetching judgment means 21 of the reception computer 20 takes in data to which the destination list which is to be received later is not added by including added data. Thus, the reception computer becomes limited, and the communication overhead is reduced.
