Abstract
Official abstract text for this publication.
A topology estimation system that estimates the connection relationship of interfaces of a plurality of devices includes: a topology estimation device 1 that estimates the connection relationship of the interfaces from the correlation of traffic observed at each of the interfaces connected to each other; and a traffic generation device 4 that generates traffic to be transmitted to the interfaces. The traffic generation device 4 includes: a traffic generation unit 42 that generates traffic so that a different feature amount appears for each set of the interfaces connected to each other; and a traffic transmitting unit 43 that transmits the traffic to the interfaces.

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 from a correlation of traffic 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 traffic to be transmitted to the interfaces, the traffic generation device including: a traffic generation unit, including one or more processors, that is configured to generate traffic so that a different feature amount appears for each set of the interfaces connected to each other; and a traffic transmitting unit, including one or more processors, that is configured to transmit the traffic to the interfaces. 2 . A traffic generation device that is configured to generate traffic for estimating a connection relationship of interfaces connected to each other from a correlation of the traffic observed at each of the interfaces, comprising: a traffic generation unit, including one or more processors, that is configured to generate the traffic so that a different feature amount appears for each set of the interfaces connected to each other; and a traffic transmitting unit, including one or more processors, that is configured to transmit the traffic to the interfaces. 3 . The traffic generation device according to claim 2 , wherein the traffic generation unit is configured to generate a different amount of traffic for each destination interface. 4 . The traffic generation device according to claim 3 , wherein the traffic generation unit is configured to subdivide the destination interfaces into a plurality of groups and generate the traffic so as to be transmitted at a different timing for each group. 5 . The traffic generation device according to claim 2 , wherein the traffic generation unit is configured to generate the traffic so as to be transmitted at a different timing for each destination interface. 6 . The traffic generation device according to claim 5 , further comprising: a lower-limit value calculation unit, including one or more processors, configured to calculate a lower-limit value of a transmission time of the traffic on the basis of a traffic sampling interval at the interface. 7 . A traffic generation method of generating traffic for estimating a connection relationship of interfaces connected to each other from a correlation of the traffic observed at each of the interfaces, comprising: generating the traffic so that a different feature amount appears for each set of the interfaces connected to each other; and transmitting the traffic to the interfaces. 8 . The topology estimation system according to claim 1 , wherein the traffic generation unit is configured to generate a different amount of traffic for each destination interface. 9 . The topology estimation system according to claim 8 , wherein the traffic generation unit is configured to subdivide the destination interfaces into a plurality of groups and generate the traffic so as to be transmitted at a different timing for each group. 10 . The topology estimation system according to claim 1 , wherein the traffic generation unit is configured to generate the traffic so as to be transmitted at a different timing for each destination interface. 11 . The topology estimation system according to claim 10 , further comprising: a lower-limit value calculation unit, including one or more processors, configured to calculate a lower-limit value of a transmission time of the traffic on the basis of a traffic sampling interval at the interface. 12 . The traffic generation method according to claim 7 , comprising: generating a different amount of traffic for each destination interface. 13 . The traffic generation method according to claim 12 , comprising: subdividing the destination interfaces into a plurality of groups and generate the traffic so as to be transmitted at a different timing for each group. 14 . The traffic generation method according to claim 7 , comprising: generating the traffic so as to be transmitted at a different timing for each destination interface. 15 . The traffic generation method of claim 14 , comprising: calculating a lower-limit value of a transmission time of the traffic on the basis of a traffic sampling interval at the interface.
