step 201: and acquiring the health states of the main intelligent network card and the standby intelligent network card.
In the embodiment of the invention, various realization modes for acquiring the health states of the main intelligent network card and the standby intelligent network card are provided, in one realization mode, a first health detection program is installed on the main intelligent network card, a second health detection program is installed on the standby intelligent network card, and after the first health detection program is started, the health state of the main intelligent network card is monitored in real time based on the first health detection program, and the health state of the main intelligent network card is sent to the controller. And after the second health detection program is started, the health state of the standby intelligent network card is monitored in real time based on the second health detection program, and the health state of the standby intelligent network card is sent to the controller, so that the controller determines whether the switching of the main intelligent network card and the standby intelligent network card is required or not based on the health state of the main intelligent network card and the health state of the standby intelligent network card.
It should be specifically noted that, in the embodiment of the present invention, the main intelligent network card and the standby intelligent network card may be a corresponding relationship of 1:1,1:n, or n:n, that is, one main intelligent network card corresponds to one standby intelligent network card, or one main intelligent network card corresponds to a plurality of standby intelligent network cards, or a plurality of main intelligent network cards corresponds to a plurality of standby intelligent network cards, where the corresponding relationship of the specific main intelligent network card and the standby intelligent network card needs to be configured correspondingly based on the networking environment of the user, which is not limited specifically herein.
Step 202: and determining whether to switch the main intelligent network card and the standby intelligent network card based on the health status of the main intelligent network card and the health status of the standby intelligent network card.
In the embodiment of the invention, when the health state of the main intelligent network card is abnormal and the health state of the standby intelligent network card is in a normal state, the need of switching the main intelligent network card and the standby intelligent network card is determined. The service flow between the server and the switch is processed based on the switched main intelligent network card.
In this step, based on the health status of the main intelligent network card and the standby intelligent network card, one implementation manner of determining whether to switch the main intelligent network card and the standby intelligent network card may be: when the health state of the main intelligent network card is abnormal and the health state of the standby intelligent network card is normal, determining that the main intelligent network card and the standby intelligent network card need to be switched, wherein when the operation parameters of the intelligent network card meet the preset conditions, the health state of the intelligent network card is abnormal, and when the operation parameters of the intelligent network card do not meet the preset conditions, the health state of the intelligent network card is normal.
The method comprises the steps of determining whether the health state of the main intelligent network card is an abnormal state or not, in one implementation, the operation parameters of the intelligent network card can comprise the interface states of a key service process and the intelligent network card, determining the operation state of the key service process and the interface state of the main intelligent network card, and determining that the operation parameters of the main intelligent network card meet preset conditions when the operation state of the key service process is abnormal or the interface state of the main intelligent network card is abnormal, and determining that the health state of the main intelligent network card is an abnormal state.
The interface of the main intelligent network card may include a first physical interface connected to the switch, and a virtual network interface in communication with the server, where the main intelligent network card runs a first key service, a second key service, and a third key service, and the state of the first physical interface and the virtual network interface connected to the server is determined based on a first health detection program on the main intelligent network card. And determining the running states of the first key service, the second key service and the third key service based on a first health detection program on the main intelligent network card, wherein the states of the first physical interface and the virtual network interface connected with the server are in normal working states, and the running states of the first key service, the second key service and the third key service are in normal running states, so that the health state of the main intelligent network card is determined to be normal. And determining that the health state of the main intelligent network card is in an abnormal working state when any one of the first physical interface and the virtual network interface connected with the server is in an abnormal working state, and determining that the health state of the main intelligent network card is in an abnormal state when any one of the operation states of the first key service, the second key service and the third key service is in an abnormal operation state.
The implementation manner of determining whether the health status of the standby intelligent network card is normal may refer to the description of determining the health status of the main intelligent network card, which is not described herein.
Based on the health status of the main intelligent network card and the health status of the standby intelligent network card, another implementation manner of determining whether to switch the main intelligent network card and the standby intelligent network card may be: and when the health state of the main intelligent network card cannot be acquired and the health state of the standby intelligent network card is in a normal state, determining that the main intelligent network card and the standby intelligent network card need to be switched.
In an example, the controller may actively acquire the health status of the main intelligent network card and the standby intelligent network card, and switch the main intelligent network card and the standby intelligent network card when the controller cannot acquire the health status of the main intelligent network card and the health status of the acquired standby intelligent network card is normal.
In another example, when the main intelligent network card cannot send the health status to the controller, the controller determines that the health status of the main intelligent network card cannot be obtained, and when the health status of the standby intelligent network card is in a normal status, the main intelligent network card and the standby intelligent network card are switched.
Step 203: if yes, adjusting the interface states of member interfaces in the first link aggregation group, and adjusting the link aggregation control protocol LACP packet sending states of the member interfaces in the second link aggregation group and the third link aggregation group, so that the main intelligent network card is switched to a new standby intelligent network card, and the standby intelligent network card is switched to the new main intelligent network card.
In this step, the server is configured with a first link aggregation group, and the first link aggregation group is formed by statically aggregating a first virtual network interface connected with the main intelligent network card and a second virtual network interface connected with the standby intelligent network card. The main intelligent network card is configured with a second link aggregation group, and the second link aggregation group is formed by dynamically aggregating first physical interfaces of the main intelligent network card connected with the switch. The standby intelligent network card is provided with a third link aggregation group which is formed by dynamically aggregating second physical interfaces of the standby intelligent network card, which are connected with the switch. The main intelligent network card and the server communicate through a first virtual network interface, and the main intelligent network card and the switch communicate through a first physical interface. The standby intelligent network card is communicated with the server through a second virtual network interface, and the standby intelligent network card is communicated with the switch through a second physical interface.
When the switching between the main intelligent network card and the standby intelligent network card is determined to be needed based on the above mode, the switching can be realized by adjusting the interface states of the member interfaces in the first link aggregation group and the LACP (Link Aggregation Control Protocol ) packet sending states of the member interfaces in the second link aggregation group and the third link aggregation group.
Before the health states of the main intelligent network card and the standby intelligent network card are acquired, setting the interface states of the member interfaces in the first link aggregation group as default states, and setting the LACP packet sending states of the member interfaces in the second link aggregation group and the third link aggregation group as default states.
As shown in fig. 4, the manner of setting the interface states of the member interfaces in the first link aggregation group to the default state and the LACP packet sending states of the member interfaces in the second link aggregation group and the third link aggregation group to the default state may include the following steps:
step 301: the interface state of the first virtual network interface in the first link aggregation group is set to an on state.
Step 302: the interface state of the second virtual network interface in the first link aggregation group is set to a closed state.

Fig. 6 is a schematic diagram of interfaces of a main intelligent network card, a standby intelligent network card, a server and a switch in the intelligent network card switching system. The server is configured with a first link aggregation group Bond1, the Bond1 is formed by static aggregation of a first virtual network interface Vnet1 connected with a main intelligent network card and a second virtual network interface Vnet2 connected with a standby intelligent network card, the main intelligent network card is configured with a second link aggregation group Bond11, the Bond11 is formed by dynamic aggregation of a first physical interface Eth1 connected with a switch of the main intelligent network card, the standby intelligent network card is configured with a third link aggregation group Bond12, and the Bond12 is formed by dynamic aggregation of a second physical interface Eth2 connected with the switch of the standby intelligent network card. The main intelligent network card is communicated with the server through a first virtual network interface Vnet1, and the main intelligent network card is communicated with the switch through a first physical interface Eth 1; the standby intelligent network card and the server communicate through a second virtual network interface Vnet2, and the standby intelligent network card and the switch communicate through a second physical interface Eth 2. The switch is configured with a fourth link aggregation group Bond13, and the Bond13 is formed by dynamically aggregating a third physical port P1 connected with the main intelligent network card of the switch and a fourth physical port P2 connected with the standby intelligent network card of the switch. The LACP operation modes of the third physical port P1 and the fourth physical port P2 in Bond13 are set to the passive mode.
The controller sets the interface state of the first virtual network interface Vnet1 in the first link aggregation group Bond1 of the main intelligent network card to UP (i.e. ON state), sets the interface state of the second virtual network interface Vnet2 in the first link aggregation group Bond1 to DOWN (i.e. off state), and sets the LACP packet sending state of the first physical interface Eth1 in the second link aggregation group Bond11 to ON (i.e. ON state), so that the first physical interface Eth1 in the second link aggregation group Bond11 enables the sending of the LACP message, after receiving the corresponding LACP message, the forwarding state of the third physical port P1 in Bond13 of the switch is changed to the selected state, and the port in the selected state can normally receive the message.
The controller sets the state of the LACP packet sending state of the second physical interface Eth2 in the third link aggregation group Bond 12 with the intelligent network card to OFF (i.e. the closed state), so that the second physical interface Eth2 in the third link aggregation group Bond 12 with the intelligent network card closes the LACP message sending, the fourth physical port P2 in Bond13 of the switch cannot receive the LACP message, the forwarding state of P2 will be changed into the unselected state, and the port in the unselected state will not normally receive the message.
In the embodiment of the invention, the switching between the main intelligent network card and the standby intelligent network card is realized by adjusting the interface states of the member interfaces in the first link aggregation group and adjusting the link aggregation control protocol LACP packet sending states of the member interfaces in the second link aggregation group and the third link aggregation group, and the specific implementation modes of the switching between the main intelligent network card and the standby intelligent network card can be as follows:
and switching the interface state of the second virtual network interface in the first link aggregation group to an on state, switching the interface state of the first virtual network interface in the first link aggregation group to an off state, switching the LACP packet sending state of the second physical interface in the third link aggregation group to an on state, and switching the LACP packet sending state of the first physical interface in the second link aggregation group to an off state.
In an example, when switching between the primary and standby intelligent network cards, the controller sends a switching instruction to the server to switch the interface states of the first and second virtual network interfaces, and the server sets the interface state of the first virtual network interface connected to the primary intelligent network card to DOWN (i.e., off state) based on the switching instruction. The server sets the interface state of the second virtual network interface connected with the standby intelligent network card to be UP (i.e. on state).
In another example, a switching instruction for switching the interface states of the first virtual network interface and the second virtual network interface is indirectly issued to the server by the main intelligent network card or the standby intelligent network card, and the server completes switching the interface states of the first virtual network interface and the second virtual network interface based on the switching instruction.
The controller sets the LACP packet sending state of the second physical interface Eth2 in the third link aggregation group Bond 12 to be ON (i.e. open state), so that the second physical interface Eth2 in the third link aggregation group Bond 12 enables sending of the LACP packet, and after receiving the corresponding LACP packet, the forwarding state of the fourth physical port P2 of the switch is changed to a selected state, and the port in the selected state can normally send and receive the packet.
The controller sets the LACP sending state of the first physical interface Eth1 in the Bond 11 of the second link aggregation group to be OFF (i.e. closed state), so that the first physical interface Eth1 in the Bond 11 of the second link aggregation group closes the LACP message sending, the third physical port P1 of the switch cannot receive the LACP message, the forwarding state of the P1 is changed into an unselected state, and the port in the unselected state cannot normally receive and send the message, thereby realizing link switching of the message sending on the switch.
