PROBLEM TO BE SOLVED: To estimate the relation of connection (topology) between IFs while enhancing accuracy, even if the measuring method of the transmission and reception traffic amount of each device (node) is different.SOLUTION: A topology estimation device 1 is configured to include a processing section 10 for extracting an accidental fluctuation, i.e., a fluctuation not having commonality on the transmission side and reception side, by removing the fluctuation component common to each traffic component, from the time series information of each traffic on the transmission side and reception side between the IFs of the node, when estimating the relation of connection between nodes as a device constituting a network, and determining that there is the relation of connection between the IFs, if there is synchronism in the time series information of each accidental fluctuation thus extracted. |
