Embodiments of the present invention provide a control device, a system, and a transmission channel control method in SDN. According to technical solutions provided in the embodiments of the present invention, a connection status of a control channel is acquired, it is determined, according to a preset threshold, whether a standby channel is suitable to continue serving as a standby channel; when the standby channel is congested to a specific extent, the standby channel is adjusted and another uncongested channel is set as a standby channel; and when an active channel is congested, the standby channel is switched to an active channel, so that real-time channel adjustment is ensured, effective transmission of control information is ensured, and control reliability of a control device in SDN is improved. |
