Communication path designing method, communication path designing device, and program to have computer execute same method

摘要

A communication path designing method and a communication designing device enabling an effective use of a network resource while satisfying requirements specified according to a service class is provided. The method for designing the communication path on a network having a plurality of links and nodes includes processing of creating a path candidate use device function and condition to produce a constraint expression serving as a constraint condition to select a communication path that can satisfy a traffic demand, processing of creating a first link receiving condition to produce a constraint expression serving as a constraint condition based on a resource of a network to be shared according to a plurality of service classes, processing of creating a second link receiving condition to produce an objective function to be used as a reference to select a communication path, and processing of optimization to design the communication path by solving a mathematical programming problem made up of the above various constraint expressions and objective functions.
