1. A topology estimation system comprising:
a topology estimation device configured to determine, from a correlation between traffic volumes at a plurality of interfaces of a plurality of devices, a connection relationship of the plurality of interfaces; and
a traffic addition device, the traffic addition device comprising:
a traffic addition unit configured to add to traffic volumes output from the plurality of interfaces additional traffic volumes that are different at the plurality of interfaces, respectively; and
a traffic volume calculation unit configured to calculate, according to the traffic volumes flowing through the plurality of interfaces, the additional traffic volumes to be added to the traffic volumes, respectively, wherein each additional traffic volume to be added to a respective interface is calculated as a predefined percentile of an average traffic volume through the plurality of interfaces.
