PROBLEM TO BE SOLVED: To lighten the load of processes and the load of storage capacity on each client by efficiently sorting only information needed for users on the client sides when a server distributes information to the clients. SOLUTION: A distributing machine 100 distributes a reference point and the distances from each node to a reference point which are calculated by a distance calculation part 102 prior to the distribution of the nodes and receivers 110 and 120 having received them from the machine 100 calculate the distances between a representative point selected by a representative point selection part 113 and the reference point and a distance calculation part 114 calculates the distance from the representative point to nodes as distribution destinations according to the axiom of the distance when receiving the contents of the nodes.
