Abstract
A route calculation control device includes a calculator configured, among a plurality of nodes constituting a physical network having a plurality of sections to which respective policies different from each other are applied when allocating resources, based on a policy corresponding to a section including a start point node specified in a use request of the resources of the physical network, to calculate a route from the start point node to an end point node specified in the use request; and a controller configured to replace the start point node, among nodes constituting the route calculated by the calculator, with a first node included in a section different from the section including the start point node, so as to cause the calculator to calculate a route to the end point node. This enables to allocate resources to a network that includes multiple sections to which different policies are applied.
