The embodiment of the invention provides a dual hot standby switching method and device. The method comprises the following steps: a main device sends a network state detection message to connected uplink and downlink routing reachable equipment; if the response message fed back by the corresponding route reachable device is not received, the detection result or the switching request are sent to the standby device, so that the standby device is switched to a new main device; and if a switching success message sent by the new main device is received, the main device is switched to the standby device. The method is implemented by sending a network state detection message and receiving a response message through main equipment, and switching between the main device and the standby device canbe achieved as long as response messages of upper and lower networking gateways or server equipment can be received under the condition that the existing topological environment and configuration of aclient are not modified. The situation that the main and standby links cannot be switched due to false death of the uplink and downlink equipment is avoided. Meanwhile, only a hot backup device needsto be configured, the system modification amount is small, and the development and maintenance cost is low.
