Abstract (in Japanese) (See Japanese page) 
(in English) Acquisition and estimation of topologies of large-scale evolving networks
such as communication networks and social networks are not trivial because
of their scale, complexity, and dynamics. In general, the topology of a
communication network can be represented as a graph composed of many
vertices and edges. A network topology estimation problem can be formulated
as a graph topology estimation problem with limited knowledge on the graph.
Network topology estimation problems include a range of variants depending
on the data available, constraints, and the objective function. Network
topology estimation problems can be classified into two categories: direct
and indirect. In indirect network topology estimation
problems, only information regarding the network topology to be estimated is
known. In this paper, we propose an indirect network topology estimation
method called TOPFLOW (network TOPology inference from FLOW sets),
which estimates the topology of a network from the limited number of flow
sets observed at measurement nodes in the network. Also, we extensively
investigate the effectiveness of TOPFLOW through a number of experiments
with diverse networks with different structures and scales. Our findings
include that the estimation accuracy grows almost linearly as the ratio of
measurement nodes increases in several network topologies.
