Abstract
A network design device executes the following steps: inputting a configuration condition of a network, a cost condition of the network, and a demand condition of the network; computing to solve an optimization problem with, at each base in the communication layer and computing layer, an objective function for minimizing a sum of a fixed cost and a variable cost at a communication link to be placed and a computer to be placed, a demand satisfaction condition that a demand for each computer is satisfied, a flow conservation condition that a traffic flow rate for a demand for each computer is conserved, and a capacity constraint that is a constraint due to a capacity of the communication link and computer at each base; and outputting a placement and a capacity of each of the communication link and computer obtained by the computing.
