| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we consider the problem of estimating the traffic rate of every unobservable global flow (individual-flows) between corresponding origin-destination (OD) pair based on the traffic rate of aggregated flow (aggregated-flows), which can be easily measured at certain links (e.g., router interfaces) in a network. The inverse function method solves the problem by mapping from the probability distributions of the traffic rate of aggregated-flows to those of individual-flows. However, the inverse function method has a problem that the estimation accuracy is reduced due to the uncertainty of the solution in the OD traffic matrix estimation. In order to solve this problem, we focus on the fact that the OD traffic matrix estimation defined on the real topology can be transformed into the equivalent estimation defined on the pseudo topology. By integrating the multiple estimation results obtained by applying the inverse function method to each of the real topology and the pseudo topology, the uncertainty of the solution is reduced, and the estimation accuracy of the individual flow rate distribution is improved. | |
