A method for implementing an active/standby switchover includes: sending received data to an active device corresponding to a physical IP address in a mapping relation with a preset communication identification (ID); changing the physical IP address of the active device in the mapping relation with the communication ID to the physical IP address of a standby device for switchover when determining that the system needs to perform the active/standby switchover; sending the received data to the standby device corresponding to the physical IP address in the mapping relation with the preset communication ID after the system performs the active/standby switchover. A system and device for implementing an active/standby switchover are also disclosed. With the method, system, and device provided by the present invention, a long interruption of ongoing services is prevented when the active/standby switchover is performed.
