Embodiment 1
[0043] This embodiment will be described from the perspective of a gateway disaster recovery device. The gateway disaster recovery device is specifically a gateway device in a gateway device cluster. The gateway device may be a device that provides a gateway function, such as a server that provides a gateway function.
[0044] A gateway disaster recovery method, applicable to gateway devices in a gateway device cluster, comprising: sending heartbeat packets to other gateway devices and switches in the gateway device cluster, and receiving heartbeat packets sent by the other gateway devices. When the heartbeat packet sent by the other gateway device is not received, it is determined that the other gateway device is faulty, obtain the first network egress address configured on the other gateway device, and assign the first network egress address to the gateway device cluster The normal gateway device takes over.
[0045] Such as Figure 1a As shown, the specific process of the g...
Embodiment 2
[0100] According to the method described in Embodiment 1, it will be further described in detail below.
[0101] Such as Figure 2a As shown, this embodiment provides a network data interaction system, which includes: a gateway device cluster, a first network switch, and a second network switch; wherein, the gateway device cluster includes a plurality of gateway devices, and the gateway device can provide a gateway A functional device, such as a server (LD) providing a NAT gateway function, the gateway device cluster is connected to the first network switch through the first network, and connected to the second network switch through the second network.
[0102] The following will be based on Figure 2a The network data interaction system shown is used to further describe the gateway disaster recovery method of the present invention.
[0103] Such as Figure 2b As shown, a gateway disaster recovery method, the specific process can be as follows:
[0104] 201. Each gateway ...
Embodiment 3
[0150] In order to better implement the above method, the embodiment of the present invention also provides a gateway disaster recovery device, which is suitable for gateway devices in a gateway device cluster, such as Figure 3a As shown, the gateway disaster recovery device includes: a heartbeat sending unit 301, a heartbeat receiving unit 302, a fault determining unit 303, an address obtaining unit 304, and an allocating unit 305, as follows:
[0151] (1) Heartbeat sending unit 301;
[0152] The heartbeat sending unit 301 is configured to send heartbeat packets to other gateway devices and switches in the gateway device cluster.
[0153] In this embodiment, the gateway device may include a device that provides a NAT (Network Address Translation, network address translation) gateway function, for example, an LD (a server that provides a NAT gateway function) and the like.
[0154] Wherein, the mode of sending heartbeat packet can include multicast sending method etc., for e...
