Patent ID: 7835296

Claim:
A system for analyzing network traffic according to the amount of communication, the system comprising: a data measurement module which measures data of a change in communication traffic between a server and a plurality of clients in a network; a log database which stores the data; a measured data functionizing module which obtains a probability density distribution or a cumulative distribution based on the data stored in the log database; a distribution function database which stores function information on a theoretically generalized distribution; a parameter decision module which applies the data to the function information stored in the distribution function database and selects parameters such that the function information is related with the data; a suitability check module which compares the function information, to which the parameters are applied, with the probability density distribution or the cumulative distribution obtained by the measured data functionizing module and selects function information similar to the probability density distribution or the cumulative distribution from among the function information; and a valid section setting module which sets a valid section by excluding data beyond a predetermined reference with respect to a variance or a standard deviation of the data stored in the log database, wherein the measured data functionizing module obtains the probability density distribution or the cumulative distribution using data within the valid section.
