DEVICE, SYSTEM, METHOD AND PROGRAM FOR CALCULATING COMMUNICATION TRAFFIC

摘要

PROBLEM TO BE SOLVED: To improve the accuracy of estimation of a communication traffic amount among the respective nodes in a network.

SOLUTION: A device 10 for calculating communication traffic calculates an initial value tg of an estimation value of a communication traffic amount in a communication network 40 by a gravity method. The device compares the initial value tg with an actual measurement value of a traffic amount of a flow in the communication network 40. In this case, when an error between the initial value tg and the actual measurement value is large, the initial value tg is corrected by the actual measurement value, and an estimation value Testof the communication traffic amount is calculated by a TomoGravity method using the corrected initial value tg.
