P2P NETWORK SYSTEM AND PROGRAM FOR GROUP MANAGEMENT IN P2P NETWORK

摘要

PROBLEM TO BE SOLVED: To efficiently prevent multiplication of commands, to decrease communication traffic and to improve responsiveness as a network in a P2P network system exchanging resources between a plurality of nodes that belong to a group.;SOLUTION: After an autonomous connection between nodes is generated, it is determined whether or not both the connected nodes belong to the same group and if it is determined that both the nodes do not belong to the same group, the connection between both the nodes is cut off, so that even if a node is autonomously connected to another node, only the connection between nodes that belong to the same group is maintained but the connection between nodes that does not belong to the same group is cut off. Thus, expansion of groups is prevented and extremely many command propagations can be prevented from occurring on a network within a group.;COPYRIGHT: (C)2011,JPO&INPIT
