摘要

PROBLEM TO BE SOLVED: To efficiently retrieve data having multidimensional attributes at high speed.;SOLUTION: A plurality of peers 110, 120, ... are connected in a network 100. Each of peers 110, 120, ... has the data in common in an overlay network (P2P network) at a high level layer of the existing network 100. Each peer 110, 120, ... converts the data having a plurality of attributes into a one-dimensional value, generates a logical identifier by applying a distribution function on the one-dimensional value, specifies the other peer for managing the logical identifier generated based on assignment of logical identifiers for each of peers 110, 120, ... in the overlay network, and registers the data in the other specified peer.;COPYRIGHT: (C)2009,JPO&INPIT
