A communication path switching device is configured to determine whether or not a specified network device where exclusion from a communication path or addition to the communication path is specified through an input device can perform path switching based on the individual pieces of information on a coupling configuration and a presence or absence of an independent control function; refer to a storage device for the individual pieces of information on the coupling configuration and a coupling policy to change the coupling policy according to a result of the determination; and processing of issuing, according to the result of the determination and the individual pieces of information in the storage device, a path switching instruction to a network device having the independent control function and a network device not having the independent control function that are path switching targets on a communication path directed to the specified network device.
