In this embodiment, the determining that the current device is the master device or the standby device may include: and determining that the current equipment is the main equipment or the standby equipment according to the role information of the current equipment.
Step 102: and multicast sending the notification message according to a preset time period.
When it is determined that the current device is the master device, the current device, that is, the master device, needs to multicast and send a notification message according to a preset time period. The advertisement message may include, but is not limited to, a VIP address and a priority level.
Among these, with respect to VIP: when the dual-computer hot-standby scheme is used for networking, in the dual-computer hot-standby scheme, the main device and the standby device are both independent routers and have own IP addresses, but the whole router is externally presented as a virtual router and externally presented with virtual IP addresses, and the virtual IP addresses are different from the IP addresses of the main device and the standby device, and are referred to as VIPs for short. In actual operation, the virtual router is actually operated by the host device.
The priority level is a priority level of a device that sends the notification packet, that is, a priority level of the master device in this embodiment.
Step 103: and receiving an announcement message sent by the main equipment.
When the current device is determined to be the standby device, the current device, that is, the standby device, may receive the notification message multicast-sent by the main device when the main device is not faulty.
Step 104: when the VIP address in the notification message is the same as the VIP address of the standby device, the standby device determines whether the priority in the notification message is greater than the priority of the standby device, and if not, the process proceeds to step 105.
As noted above, the VIP is a virtual IP address common to both the primary and backup devices.
After receiving the notification message sent by the main device, the standby device may compare the VIP address in the notification message with its own VIP address to see whether the VIP addresses are the same or not, and if not, may not perform any processing. If the two messages are the same, the received notification message is sent by the master device, and whether subsequent related operations are executed or not needs to be judged according to the information in the notification message.

step 201: and determining that the current equipment is the main equipment or the standby equipment, if the current equipment is the main equipment, entering the step 202, and if the current equipment is the standby equipment, entering the step 203.
Step 202: and multicast sending the notification message according to a preset time period.
Step 203: and receiving an announcement message sent by the main equipment.
Step 204: when the VIP address in the notification message is the same as the VIP address of the standby device, the standby device determines whether the priority in the notification message is higher than the priority of the standby device, and if not, the process proceeds to step 205.
Wherein the VIP is an IP address common to the primary device and the backup device.
Step 205: and the standby equipment switches the role of the standby equipment into the role of the main equipment and executes the service work of the main equipment.
Step 206: and resetting the number of the continuous unreceived main equipment notification messages to be 0.
In this embodiment, the number of consecutive unreceived main device advertisement messages needs to be configured in advance in the device, the initial value of the number of consecutive unreceived main device advertisement messages is 0, and the number of consecutive unreceived main device advertisement messages is reset to 0 by the standby device each time after receiving an advertisement message sent by the main device.
In addition, in this embodiment, a time interval for the device to send or receive the notification message may also be preconfigured, that is, a preset time period, and each time the device does not receive the notification message sent by the master device in the preset time period, the number of the consecutive unreceived master device notification messages may be increased by 1.
Step 207: and judging whether the number of the continuously unreceived main device notification messages is larger than or equal to a preset value, if so, entering step 205.
The determining whether the number of the consecutive unreceived master device advertisement messages is greater than or equal to a preset value may specifically include: and judging whether the time for continuously not receiving the main equipment notification message is more than or equal to N preset time periods, wherein N is equal to the preset value.
If the standby device does not receive the notification message sent by the main device within a plurality of continuous preset time periods, it indicates that the main device may have a fault or the main device does not exist currently, and in this case, the standby device switches its role to the role of the main device and executes the service work of the main device to provide normal service.
In this embodiment, the number of consecutive unreceived main device notification messages is preset in the device, and when the number of consecutive unreceived main device notification messages satisfies a certain condition, it is determined that the main device fails or does not exist, and the standby device switches its role to the main device to provide a normal service.
