DISTRIBUTED SYSTEM, COMMUNICATION MEANS SELECTING METHOD AND COMMUNICATION MEANS SELECTING PROGRAM

摘要

A distributed system comprising a plurality of nodes each of which includes a plurality of communication means and is characterized by: a storing means for storing information of the physical positions of the nodes and information of identification of applications operating on the nodes with the former information associated with the latter information; a communication means determining means that, when the application operating on a first node communicates with the application operating on a second node, extracts, based on the information of identification of applications, the information of the positions of the first and second nodes from the storing means and then determines, based on the extracted information of the positions, an optimum communication means from the plurality of communication means; and a communication means selecting means for selecting the communication means on the basis of the result of that determination of the communication means determining means.
