In this embodiment, a method for detecting network card connectivity is provided, and fig. 2 is a flowchart of the method for detecting network card connectivity provided in the embodiment of the present application, where an execution main body of the method may be an electronic device, and optionally, the electronic device may be a server or a terminal device, but the present application is not limited thereto. Specifically, as shown in fig. 2, the process includes the following steps:
step S201, determining a gateway MAC address of the network card to be tested and an IP address of a target server.
Exemplarily, a network card to be tested in the terminal device is determined, a Media Access Control Address (MAC), that is, an MAC Address, of the network card to be tested is determined based on the network card to be tested, and an Internet Protocol Address (IP), that is, an IP Address, of the target server is obtained.
Specifically, the terminal device may include multiple network cards such as an ethernet, a wireless network (wifi), a fourth generation mobile communication (4G), and the like, in order to save overhead, the ethernet is usually set as a default network card, and then other network cards such as wifi and 4G may be standby network cards, and the network card to be tested may be any one of the standby network cards.
It should be noted that the overhead in the embodiment of the present application may refer to performance overhead or cost overhead, and generally, a network card with one access mode with lower overhead among multiple network card access modes is determined as a default network card. When the default network card fails, the terminal device needs to switch to another network card to ensure the continuation of the service. When the default network card is recovered, the terminal device needs to switch back to the default network card to reduce the overhead of the whole service. That is, if the terminal device communicates with the target server through the standby network card currently, the network card to be tested may be the default network card. The network card to be tested can be set according to actual requirements, and is not limited herein. In the embodiment of the present application, only three network cards, that is, an ethernet card, a wifi card, and a 4G card, may be included in the terminal device, and in practical application, the terminal device may further include a network card for fifth-generation mobile communication (5G), a network card for third-generation mobile communication (3G), and the like, which is not limited herein.
It should be noted that the target server may refer to a public network server, that is, a server of a remote network connecting computers of local area networks or metropolitan area networks in different regions for communication.
Step S202, a test request is generated based on the gateway MAC address and the IP address of the target server.
Illustratively, the test request may be a data packet, where the data packet at least includes a destination MAC and a field corresponding to a destination IP, and may create an original socket, directly write the determined gateway MAC address into the field corresponding to the destination MAC in an encoding manner, and write the destination server IP address into the field corresponding to the destination IP, thereby generating the test request of the network card to be tested.
Step S203, sending the test request to the gateway of the network card to be tested through the socket, so that the gateway of the network card to be tested forwards the test request to the target server.
Further, the test request of the network card to be tested is sent to the gateway of the network card to be tested through the original socket, so that the gateway of the network card to be tested sends the test request to the target server. Therefore, when the connectivity test of the network card is carried out, the network card to be tested does not need to be selected by a route, even if the connectivity test of the network card to be tested is carried out in the process of carrying out service communication between the default network card and the target server, the default network card does not need to be disconnected by the route and is switched to the network card to be tested, and the normal communication of the current service is ensured.
And step S204, receiving feedback information forwarded by the gateway of the network card to be tested, and determining the connectivity of the network card to be tested and the target server based on the feedback information.
Wherein the feedback information may be generated by the target server based on the test request.
Specifically, after receiving the test request, the target server generates feedback information according to the test request, and forwards the feedback information to the network card to be tested through the gateway of the network card to be tested, so that the network card to be tested receives the feedback information.
Further, the electronic device acquires feedback information received by the network card to be tested, and determines connectivity between the network card to be tested and the target server according to the feedback information.
In the implementation process, a test request is directly generated according to the MAC address of the network card to be tested and the IP address of the target server, and further, the test request is sent to the gateway of the network card to be tested through the socket, so that the gateway of the network card to be tested forwards the test request to the target server, the gateway of the network card to be tested does not need to be selected through a route, namely, the gateway of the current service network card cannot be interrupted due to the connectivity test of the network card to be tested in the process of service communication between the terminal device and the server, the connectivity detection of the network card is realized in the service communication process, and the normal communication of the service is ensured. And the connectivity between the network card to be tested and the target server can be further conveniently determined according to the feedback information of the target server, so that a connectivity detection result can be obtained.
In some embodiments, determining the gateway MAC address of the network card to be tested may include the following steps:
step 1: and determining the gateway IP address of the network card to be tested.
And 2, step: a gateway MAC address is determined based on the gateway IP address.
Illustratively, there is a corresponding gateway for each network card, the gateway IP address is a "gateway" of one network to other networks, and is mainly used for data transmission between different networks, and the gateway MAC address, i.e. a physical address, is used to define the location of a network device.
The IP address of the corresponding gateway can be determined according to the network card to be tested, and further, the MAC address of the gateway can be determined according to the IP address of the gateway.
In the implementation process, the gateway MAC address is determined according to the gateway IP address of the network card to be tested, so that the test request can be further generated according to the gateway MAC address.
In some of these embodiments, determining the gateway MAC address based on the gateway IP address comprises:
the gateway MAC address is determined based on an address resolution protocol and the gateway IP address.
Illustratively, the Protocol stack determines a gateway MAC Address corresponding to the gateway IP Address through Address Resolution Protocol (ARP).
In the implementation process, the gateway MAC address corresponding to the gateway IP address is determined according to the address resolution protocol, so that the determination of the gateway MAC address is realized.
In some embodiments, generating the test request based on the gateway MAC address and the target server IP address may include:
step 1: and creating a socket based on the network protocol type of the network card to be tested.
And 2, step: and carrying out configuration operation on the socket to obtain a target socket, wherein the configuration operation comprises the binding of the socket and the network card to be tested and the configuration of the socket without routing selection.
And step 3: and binding the IP address of the target server and the MAC address of the gateway into a preset address resolution protocol to obtain the bound address resolution protocol.
And 4, step 4: and generating a test request based on the bound address resolution protocol and the target socket.
Illustratively, the network Protocol of the network card to be tested may have multiple types, for example, an Internet Control Message Protocol (ICMP), a Transmission Control Protocol (TCP), and a User Datagram Protocol (UDP), determine the network Protocol type of the network card to be tested, and further, create a corresponding socket according to the network Protocol type of the network card to be tested.
Specifically, if the network protocol type is ICMP protocol, a socket of an Internet Packet explorer (Packet Internet Groper, PING) may be created, that is, a PING socket is created; if the network protocol type is a TCP protocol, a TCP socket can be created; if the network protocol type is UDP, a UDP socket can be created.
Further, the created socket is configured to obtain a target socket, where the configuration operation may include binding the socket with the network card to be tested, and configuring the socket without routing. Specifically, the created socket can be bound with the network card to be tested through the SO _ bidi socket option, SO that in the network card connectivity detection process, a subsequently generated test request can be conveniently sent through a gateway corresponding to the network card to be tested, and the socket can be set to be not subjected to routing through the SO _ DONTROUTE socket option, SO that the gateway of the network card to be tested does not need to be determined through a routing mode, and normal interaction of current services can be effectively ensured.
Further, the IP address of the target server and the MAC address of the gateway are bound to a preset address resolution protocol to obtain the bound address resolution protocol. Specifically, the preset address resolution protocol may be a static ARP table, and the target server IP address and the gateway MAC address are bound to the static ARP table, so that in the process of generating the test request, the gateway MAC address does not need to be determined in the wide area network through routing, and the gateway MAC address of the network card to be tested can be directly obtained through the static ARP table, so that the obtained gateway MAC address can be written into a field corresponding to the destination MAC.
Further, generating a test request through the bound address resolution protocol and the target socket, specifically, if the created socket is a PING socket, the generated test request may be a request packet; if the created socket is a TCP socket, the generated test request can be a sync packet; if the created socket is a UDP socket, the generation yes test request may be a UDP packet. The gateway MAC address and the target server IP address are directly written into the corresponding field of the test request through the target socket, so that the test request is not generated in a mode of encoding the original socket, the encoding operation in the test request generation process is simplified, and the test request generation efficiency is further improved.
In the implementation process, the created socket is bound with the network card to be tested in a socket option mode, so that the test request is forwarded through the gateway of the network card to be tested, the created socket is set to be forbidden to select the route through the socket option, the network card to be tested can also be forwarded through the gateway of the network card to be tested without selecting the route in the connectivity detection process of the network card to be tested, in addition, the IP address of the target server and the MAC address of the gateway are bound into a preset address resolution protocol, the IP address of the target server and the MAC address of the gateway can be directly written into the corresponding field of the test request in the subsequent test request generation process, the coding operation in the test request generation process is simplified, and further, the test request generation efficiency is improved.
In some embodiments, sending the test request to the gateway of the network card to be tested through the socket includes: and sending the test request to the gateway of the network card to be tested through the target socket.
Further, the generated test request is sent to the gateway of the network card to be tested through the target socket, so that the operation of routing the network card to be tested is not needed in the network card connectivity detection process, and the normal communication of the current service is ensured.

step 1: if the feedback information forwarded by the gateway of the network card to be tested is received within the preset time, the connectivity of the network card to be tested and the target server is normal.
Step 2: and if the feedback information forwarded by the gateway of the network card to be tested is not received within the preset time, the connectivity of the network card to be tested and the target server is abnormal.
Illustratively, if the feedback message forwarded by the gateway of the network card to be tested is received within the preset time, it may be determined that the connectivity between the network card to be tested and the target server is normal, and if the feedback message forwarded by the gateway of the network card to be tested is not received within the preset time, it indicates that the connectivity between the network card to be tested and the target server is abnormal.
It should be noted that the preset time in the embodiment of the present application may be 1 second, or 2 seconds, or other times, and the preset time may be adaptively set, which is not limited herein.
