Abstract: Provided are a communication network switching apparatus, a communication network switching system, and a communication network switching method. The apparatus includes a first communication network interface, a second communication network interface, a processor, a communication network switch, and a device access interface. The communication network switch is configured to switch, according to the control signal of the processor, the connection manner with the first communication network interface and the second communication network interface and connect the first communication network or the second communication network to the processor. The processor is connected to the device access interface and is configured to connect a target communication network connected through the communication network switch to a target device connected to the device access interface.
