METHOD OF DISTRIBUTING FILES, FILE DISTRIBUTION SYSTEM, MASTER SERVER, COMPUTER READABLE, NON-TRANSITORY MEDIUM STORING PROGRAM FOR DISTRIBUTING FILES, METHOD OF DISTRIBUTING DATA, AND DATA DISTRIBUTION SYSTEM

摘要

A method of distributing distribution files from a master server possessing the distribution files to servers is disclosed. The method includes generating a distribution scheme having a hierarchical structure, the tree structure including nodes and having the master server in a top node, wherein a distribution file group including the distribution files is to be allocated to each node, and a subordinate node is to include a subset of a distribution file group allocated to a superior node, which is located a level superior to the subordinate node; allocating the servers to each node, based on system status information indicating a status of the master server and/or the servers; distributing at least one distribution file to each server, based on the distribution scheme; and exchanging directly among servers corresponding to each nodes, not possessed by the servers corresponding to the respective nodes.
