1. A topology estimation system that is configured to estimate a connection relationship of interfaces of a plurality of devices, comprising:
a topology estimation device, including one or more processors, that is configured to estimate the connection relationship of the interfaces in a target network from a correlation of one or more packets observed at each of the interfaces connected to each other; and
a traffic generation device, including one or more processors, that is configured to generate the one or more packets to be transmitted to the interfaces in the target network, the traffic generation device configured to:
determine parameters for transmitting the one or more packets to each of the interfaces in the target network, wherein the parameters for transmitting comprise a size of each packet and a transmission time for each packet of the one or more packets, and the parameters for transmitting comprise an amount of the one or more packets observed at each of the interfaces to be unique;
generate, for each of the interfaces, the one or more packets according to the determined parameters for transmitting; and
transmit the one or more packets to the interfaces in the target network.
