SYSTEM AND METHOD FOR ESTIMATING NETWORK SCALE BY USING MEASUREMENT OF A PLURALITY OF POINTS, PROGRAM FOR THE SYSTEM AND METHOD, AND RECORDING MEDIUM RECORDING THE PROGRAM

摘要

PROBLEM TO BE SOLVED: To estimate the scale of nodes belonging to a large-scale network system such as P2P network.;SOLUTION: The identification information of nodes belonging to the same network is collected by measuring nodes 1 to 3 arranged on a plurality of points on the same network 5, the identification information of other measuring nodes is also collected, and time required for detecting the other measuring node is measured by comparing the node identification information with the other measuring node identification information to estimate the total number of nodes belonging to the network service system 5.;COPYRIGHT: (C)2007,JPO&INPIT
