The main interface sends 1 to 3 data packets to the two-layer switch of the opposite terminal to establish the MAC forwarding table entry, and if the two-layer switch is not connected, the sending packet does not have any side effect. Otherwise, the configuration state information is that the link interface corresponding to the online state is a main interface, the link interface corresponding to the offline state is a backup interface, an IP address is allocated to the main interface, the backup interface may not configure the IP address or configure a garbage IP address such as 222.222.222.222, the backup interface uses the MAC address of the main interface, and turns off the transceiver function of the backup interface, and in addition, the main interface sends 1 to 3 data packets to the two-layer switch of the opposite end to establish the MAC forwarding table entry.

Specifically, when the network device accesses the interface, an access event of the network link is triggered, the access event is sent to the link switching state machine through the network device, the link switching state machine receives the access event, and the switching logic module is triggered to backup the current network link according to the main interface in the access event. And judging whether the access interface is a main interface or not, if the access interface is the main interface, according to the interface information of the main link and the standby link stored by the switching state machine, the IP address of the access interface is already configured, and at the moment, the switching logic module executing code sends 1 to 3 data packets to the opposite-end switch, so that the main link and the standby link of the software in the original network link are kept unchanged. Otherwise, selecting the opposite interface of the link where the access interface is located as the main interface, if the state information of the opposite interface is in an off-line state, the access interface is the main interface, configuring the IP address of the access interface according to the interface information of the main link and the standby link stored by the link switching state machine, opening the transceiving function, transmitting 1 to 3 data packets by the access interface at the same time, enabling the two-layer switch of the opposite end to establish the MAC forwarding table entry, in addition, closing the opposite interface to be the backup interface, not configuring the IP address or configuring a garbage IP address such as 222.222.222.222, and switching off the transceiving function of the backup interface and backing up the current network link.

And judging whether the disconnected interface is a backup interface or not, if the disconnected interface is the backup interface, keeping the main and backup links of the software in the original network link unchanged, maintaining the working state of the link backup system, and waiting for any one of the two interfaces to generate link state switching. On the contrary, the opposite-layer switch of the link where the disconnection interface is located is a backup interface, and further judges whether the state information of the opposite-layer interface is online, if yes, the switching logic module switches the main interface and the backup interface of the current network link, the opposite-layer interface is the main interface, an IP address is configured for the opposite-layer interface, the transceiving function of the opposite-layer interface is opened, 1 to 3 data packets are sent by the opposite-layer interface, the two-layer switch of the disconnection interface establishes an MAC forwarding table entry, meanwhile, the disconnection interface is the backup interface, the IP address is not configured or a garbage IP address such as 222.222.222.222 is configured, the transceiving function of the disconnection interface is turned off, and further the current network link of the backup is fed back to the link backup system, so that the link backup system enters the working state, and any one of the two interfaces is waited for generating the link state switching.
If not, keeping the main and standby links of the software in the original network link unchanged, maintaining the working state of the link backup system, and waiting for any one of the two interfaces to generate link state switching.
And 106, restarting the software system according to the backed-up current network link.
When the network links of all software in the system are switched, the software system needs to be restarted, so that the embedded product can be matched with the current network environment.
In the network link dual-backup method, the physical connection between the network equipment and the network can be realized through the initialization of the network interface, so that the network equipment can be ensured to normally communicate with the outside. The method comprises the steps of configuring a main link and a standby link of software according to state information of a network link in network equipment, enabling the main link and the standby link to be tightly combined with change of the state information of the network link, storing interface information of the main link and the standby link through a link switching state machine, further dynamically linking the network interface state with the link state, triggering a switching logic module after the link switching state machine receives an interrupt event, utilizing the switching logic module to be responsible for processing logic of link switching, backing up the current network link, maintaining the main link and the standby link and the like. When the network link backup is completed, the software system needs to be restarted to ensure that all network configuration information and states are updated correctly, thereby forming a link backup mechanism, and realizing automatic processing of network link faults and abnormal conditions, thereby improving the network.
In one embodiment, after the network interface is initialized, the state information of the first link and the state information of the second link are obtained according to the interface link bound by the network device, where the state information includes an online state and an offline state. If the state information of the first link is consistent with the state information of the second link, configuring the interface of the first link as a main interface and the interface of the second link as a backup interface. Otherwise, the configuration state information is that the link interface corresponding to the online state is a main interface, and the link interface corresponding to the offline state is a backup interface.

The main interface sends the data packet to the exchange of the opposite terminal to establish the MAC forwarding table item.
It is worth to say that, under the condition that both links are in an offline state, an IP address can still be allocated to the main interface, so that the risk of system breakdown caused by the fact that the network interface cannot work normally is avoided; under the condition that both links are in an on-line state, by using the MAC address of the main interface for the backup interface and closing the receiving and transmitting functions, the backup interface can be ensured to be rapidly switched to the main interface and continue to transmit data when the main interface fails. In addition, the MAC forwarding table item is established by the exchanger which transmits the data packet to the opposite terminal through the main interface, so that the data packet can be ensured to be rapidly and accurately transmitted to the target address, and the data transmission efficiency is improved.
In one embodiment, the link switching state machine receives an interruption event, and if the interruption event is an access event, triggers the switching logic module to backup the current network link according to the main interface in the access event. And if the interrupt event is a disconnection event, triggering the switching logic module to backup the current network link according to the backup interface in the disconnection event.
In one embodiment, as shown in fig. 3, the link switching state machine receives an interrupt event, if the interrupt event is an access event, triggers the switching logic module, and if the access interface is a primary interface, the switching logic module sends a data packet to the opposite-end switch to backup the primary and backup links. Otherwise, selecting the opposite interface of the link where the access interface is located as the main interface, if the state information of the opposite interface is in an off-line state, configuring the IP address of the access interface according to the interface information of the main link and the standby link stored by the link switching state machine, closing the receiving and transmitting functions of the opposite interface, and backing up the current network link. Otherwise, the main and standby links are backed up.
Therefore, when an access or disconnection event occurs, the system can immediately trigger the switching logic module and backup the current network link according to the event type, so that the data transmission is ensured not to be interrupted, and the reliability and the stability of the system are improved. Meanwhile, according to the judgment of the opposite port interface state information, a proper interface can be automatically selected as a main interface, so that the trouble and the possibility of errors caused by manual configuration are avoided, and the automation and the quick response of link switching are realized. In addition, the receiving and transmitting function of the opposite port is closed, so that network attack can be effectively prevented, and the safety of the system is improved.
In one embodiment, when the network device accesses the interface, an access event of the network link is triggered, and the access event is sent to the link switching state machine through the network device. When the network device disconnects the interface, a disconnection event of the network link is triggered, and the disconnection event is sent to the link switching state machine through the network device.
In one embodiment, the interface information of the active-standby link includes: the interface IP address of the first link, the data packet of the first link, the interface IP address of the second link and the data packet of the second link.
In one embodiment, as shown in fig. 4, when the network device interface is disconnected, a disconnection event of the network link is triggered, the disconnection event is sent to the link switching state machine through the network device, the link switching state machine receives the disconnection event, and the switching logic module is triggered to backup the current network link according to the main interface in the disconnection event. And judging whether the disconnected interface is a backup interface or not, if the disconnected interface is the backup interface, keeping the main and backup links of the software in the original network link unchanged, maintaining the working state of the link backup system, and waiting for any one of the two interfaces to generate link state switching. On the contrary, the opposite-layer switch of the link where the disconnection interface is located is a backup interface, and further judges whether the state information of the opposite-layer interface is online, if yes, the switching logic module switches the main interface and the backup interface of the current network link, the opposite-layer interface is the main interface, an IP address is configured for the opposite-layer interface, the transceiving function of the opposite-layer interface is opened, 1 to 3 data packets are sent by the opposite-layer interface, the two-layer switch of the disconnection interface establishes an MAC forwarding table entry, meanwhile, the disconnection interface is the backup interface, the IP address is not configured or a garbage IP address such as 222.222.222.222 is configured, the transceiving function of the disconnection interface is turned off, and further the current network link of the backup is fed back to the link backup system, so that the link backup system enters the working state, and any one of the two interfaces is waited for generating the link state switching.
