Provided are: a route control method that enables traffic to be efficiently accommodated while maintaining communication quality; a wireless communication system; a route control device; and a non- transient computer- readable medium. The route control method involves controlling communication routes in a network consisting of wireless links provided with an adaptive modulation function by selecting one route from a plurality of candidate routes for specific traffic. A comparison is made between the bandwidth required for the traffic , and allocatable bandwidth that can be allocated for a first candidate route that is included in the plurality of candidate routes and satisfies the stability level required for the traffic by a first modulation scheme. From the results of the comparison , if the bandwidth required for the traffic is greater than the allocatable bandwidth, a penalty cost due to transmitting the traffic using a bandwidth that can be used by a second modulation scheme having a low stability level in the first candidate route is applied , making it more difficult to be selected than the other candidate routes , and one route is selected from the plurality of candidate routes. |
