Optimum route calculation method and storage medium which stores optimum route calculation program
First Claim
1. An optimum route calculation method of calculating an optimum route in a network which has a plurality of nodes and a plurality of transmission paths that connect the nodes, and in which a cost is defined for each transmission path, comprising the steps of:
- obtaining an evaluation value on a basis of a maximum value of the cost of each transmission path included in a determined route and a route to be evaluated and a number of hops from the determined route to the route to be evaluated; and
determining a route on a basis of the evaluation value, wherein the evaluation value obtaining step comprises a step of multiplying the maximum value of the cost by the number of hops.

Abstract
In an optimum route calculation method of calculating an optimum route in a network which has a plurality of nodes and a plurality of transmission paths, and in which a cost is defined for each transmission path, an evaluation value is obtained on the basis of the maximum cost of each transmission path included in a determined route and a route to be evaluated and the number of hops from the determined route to the route to be evaluated. A route is determined on the basis of the evaluation value. A storage medium which stores the optimum route calculation program is also disclosed.
