A routing device of the present invention is included in a communication network capable of explicit routing which specifies resources included in a default path for each flow, and includes a detour path detection unit that detects a detour path which enables estimation of temporary transmission quality which can be provided to a flow within a detour region when at least a portion of an explicit default path of the flow transmitted by the routing device is detoured via resources included in a default path of another flow, and a routing unit that routes data of the flow at least to either one of the detour path and the default path, based on a difference between transmission quality of the detour path detected by the detour path detection unit and transmission quality of the default path. |
