The computing device 100 includes one or more processors and one or more readable storage media storing program instructions that, when configured to be executed by the one or more processors, cause the computing device to perform the routing information synchronization method 200 in an embodiment of the present invention.

According to one embodiment of the invention, a routing information synchronization apparatus 300 is deployed in a computing device 100, the routing information synchronization apparatus 300 being configured to perform the routing information synchronization method 200 according to the invention. The routing information synchronization apparatus 300 includes a plurality of program instructions for executing the routing information synchronization method 200 of the present invention, where the program instructions may instruct a processor to execute the routing information synchronization method 200 according to the present invention.

Fig. 2 shows a flow diagram of a routing information synchronization method 200 according to one embodiment of the invention. The method 200 is adapted to be executed in a routing information synchronization apparatus 300 of a computing device (the aforementioned computing device 100). The computing device 100 has an operating system running therein that includes a kernel that may be responsible for managing one or more network interfaces.

As shown in fig. 2, method 200 includes steps 210-250.

First, in step 210, a network data interface provided by the kernel is invoked to obtain network interface information from the kernel through the network data interface.

It should be noted that the kernel of the operating system provides the application layer with a network data interface. In one embodiment, the routing information synchronization apparatus 300 may use a polling manner to call the network data interface of the kernel, and may implement real-time acquisition of the network interface information from the kernel by polling to call the network data interface of the kernel.

In one embodiment, the network data interface may be implemented as ebpf network data interfaces.

Subsequently, in step 220, it is determined whether abnormal network interface information exists in the network interface information.

Specifically, after the network interface information is obtained from the kernel, information retrieval may be performed on the network interface information to retrieve whether abnormal network interface information exists in the network interface information.

If there is abnormal network interface information in the network interface information, the following steps 230 to 250 are performed.

In step 230, the static routing configuration file is read. Here, static routing information may be included in the static routing profile that is pre-configured for one or more network interfaces.

Subsequently, in step 240, static routing information for the abnormal network interface is obtained from the static routing configuration file based on the abnormal network interface information.

It should be noted that, the static routing configuration file is pre-generated and stored in the computing device 100. When the abnormal network interface information exists in the network interface information, a static route configuration file generated in advance can be read, and then the static route information of the corresponding abnormal network interface is obtained from the static route configuration file based on the abnormal network interface information.

Finally, in step 250, the abnormal network interface may be statically route configured according to the static route information of the abnormal network interface. In this way, the static route configuration is performed on the abnormal network interface based on the fixed static route information configured in advance for the abnormal network interface, and it is possible to ensure that the route information remains unchanged all the time when the network interface is abnormal (state changes).

Specifically, the kernel includes a network interface configuration module, where the network interface configuration module in the kernel may be called according to static routing information of the abnormal network interface, so as to perform static routing configuration on the abnormal network interface through the network interface configuration module.

According to one embodiment of the present invention, before step 210 is performed, route information input by the user is obtained in advance, and a static route profile is generated according to the route information input by the user. Here, the routing information input by the user may include fixed static routing information configured by the user for one or more network interfaces. In this way, static route configuration files are generated according to route information input by a user, and the static route configuration files can correspondingly comprise static route information corresponding to one or more network interfaces.

Specifically, when generating a static route configuration file according to route information input by a user, firstly analyzing the route information input by the user, and then requesting to set the route information to the kernel according to the route information obtained by analysis. If the setting is successful, a static route profile is generated based on the route information. I.e. the routing information is saved to a static routing configuration file. In addition, if the setting fails, the flow is ended. It should be noted that, the route information input by the user includes static network information configured by the user for one or more network interfaces, so that the generated static route configuration file includes static route information corresponding to one or more network interfaces.

Fig. 3 shows a schematic diagram of a routing information synchronization apparatus 300 residing in a computing device 100, according to one embodiment of the invention.

As shown in fig. 3, the computing device 100 has an operating system 105 running therein, and the operating system 105 includes an application layer, and the application layer is deployed with a routing information synchronization apparatus 300. The network interface configuration module 153 is included in the kernel of the operating system 105, and the kernel may provide the network data interface 151 to the application layer.

In one embodiment, as shown in fig. 3, the route information synchronization device 300 of the computing device 100 includes a retrieving module 310, a static route configuration module 330, and a reading module 320 that are sequentially connected in communication. Specifically, the retrieval module 310 is communicatively coupled to a static route configuration module 330, and the static route configuration module 330 is communicatively coupled to the reading module 320.

Wherein the retrieving module 310 is configured to perform steps 210-220, the reading module 320 is configured to perform step 230, and the static route configuration module 330 is configured to perform steps 240-250.

Specifically, the retrieval module 310 may invoke a network data interface provided by the kernel, obtain network interface information from the kernel through the network data interface, and then the retrieval module 310 determines whether abnormal network interface information exists in the network interface information. In one embodiment, the retrieval module 310 may poll the network data interface 151 of the calling kernel to obtain network interface information from the kernel in real time. And, the retrieving module 310 determines whether abnormal network interface information exists in the network interface information by retrieving the network interface information. If abnormal network interface information exists, the retrieval module 310 may send the abnormal network interface information to the static route configuration module 330.

The reading module 320 is adapted to read the static routing configuration file if there is abnormal network interface information in the network interface information.

The static route configuration module 330 may obtain the static route information of the abnormal network interface from the static route configuration file based on the abnormal network interface information, and may perform static route configuration on the abnormal network interface according to the static route information of the abnormal network interface. Specifically, the static route configuration module 330 may invoke the network interface configuration module 153 in the kernel to perform static route configuration on the abnormal network interface according to the static route information of the abnormal network interface.

That is, in step 230, the static routing configuration file is specifically read by the reading module 320, and the read static routing configuration file is sent to the static routing configuration module 330. In step 240, static route information of the abnormal network interface may be obtained from the static route configuration file based on the abnormal network interface information through the static route configuration module 330. Subsequently, in step 250, the static route configuration module 330 may perform static route configuration on the abnormal network interface (invoking the network interface configuration module 153 in the kernel) according to the static route information of the abnormal network interface.

It should be noted that, the specific execution logic of the retrieving module 310, the static route configuration module 330, and the reading module 320 may refer to the descriptions of the steps 210 to 250 in the foregoing method 200, and will not be repeated here.

According to the routing information synchronization method 200 of the present invention, network interface information is acquired from a core by calling a network data interface of the core, and it is determined whether abnormal network interface information exists in the network interface information. If the abnormal network interface information exists, static route information configured for the abnormal network interface in advance is acquired from the static route configuration file based on the abnormal network interface information, and then the static route configuration is carried out on the abnormal network interface according to the static route information of the abnormal network interface. Thus, according to the technical scheme of the invention, the network data interface is called to acquire the network interface information from the kernel, so that the instantaneity of acquiring the network interface information can be improved, and the cost of kernel interrupt is reduced. In addition, static route configuration is carried out on the abnormal network interface by reading static route information configured for the abnormal network interface in advance from the configuration file, so that the instant synchronous route information of the abnormal network interface is realized, and the route information is ensured to be always unchanged when the state of the network interface is changed.
