[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0044] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0045] Normally, in the existing function distribution process, the function distribution solution is mainly based on the container. The specific process is that the developer's local computer makes the function to be distributed into an image file based on the container, and stores the image file in the image warehouse, where the image warehouse is deployed on the cloud server. When the edge node receives the data acquisition request sent by the user, it is necessary to pull the function corresponding to the data acquisition request from the image warehouse of the cloud server to complete the distribution of the function. However, after receiving the user's data acquisition request, the function corresponding to the data acquisition request is pulled from the image warehouse of the cloud server. There are problems such as slow container startup, high resource consumption, and long function distribution time, resulting in a poor user experience. To address this problem, the embodiment of the present disclosure provides a function distribution method, which is described below in conjunction with a specific embodiment.

[0046] Figure 1 is a flow chart of a function distribution method provided by an embodiment of the present disclosure. The method can be executed by a function distribution device. The function distribution device can be implemented in software and / or hardware. The function distribution device can be configured in an electronic device, such as a server or a terminal or a server cluster. The terminal can specifically include a computer or a tablet computer, a vehicle-mounted terminal, etc. In addition, the method can be applied to Figure 2 The application scenario shown includes a cloud server 21, a first edge node 22 and a second edge node 23. It can be understood that the function distribution method provided in the embodiment of the present disclosure can also be applied in other scenarios.

[0047] like Figure 2In the application scenario shown, the cloud server 21, the first edge node 22 and the second edge node 23 can communicate through the network. The edge nodes can provide storage, computing, network and other resources, and sink some key business applications to the edge of the access network to reduce the width and delay losses caused by network transmission and multi-level forwarding.

[0048] Among them, the first edge node 22 can be an edge node corresponding to an Internet data center, and can also be understood as an edge node of a cloud vendor, such as a content delivery network node (Content Delivery Network, CDN) node.

[0049] The second edge node 23 may be an edge node on the user side.

[0050] Combine the following Figure 2 The application scenario shown is Figure 1 The function distribution method shown is introduced, for example, Figure 2 The cloud server 21 in the embodiment can execute the method. Figure 1 As shown, the function distribution method provided by the embodiment of the present disclosure includes the following steps.

[0051] S110. The cloud server sends a distribution function to a first edge node, where the first edge node is an edge node corresponding to an Internet data center.

[0052] In the disclosed embodiment, the cloud server may receive the distribution function in real time and send the distribution function to the first edge node.

[0053] A function can be understood as a small piece of code that completes simple business logic by running this small piece of code.

[0054] The distribution function refers to the function that needs to be distributed from the developer's local computer to the edge node for receiving and processing the data acquisition request sent by the user.

[0055] Specifically, the cloud server may receive the distribution function sent from the developer's local calculation based on a preset code program, and after receiving the distribution function, send the distribution function to the first edge node.

[0056] The preset code program may be a pre-set code program for receiving a distribution function, such as a fass controller service of a cloud server.

[0057] S120. The cloud server receives the target download address information corresponding to the distribution function sent by the first edge node, and saves the target download address information.

[0058] In the disclosed embodiment, after sending the distribution function to the first edge node, the cloud server receives the target download address information corresponding to the distribution function sent by the first edge node, and saves the target download address information.

[0059] In the embodiment of the present disclosure, the target download address information is the download address information corresponding to the distribution function generated by the first edge node after receiving the distribution function, and can also be understood as the storage location of the distribution function in the first edge node.

[0060] After receiving the target download address information, the cloud server saves it to the target database.

[0061] The target database is a preset database in the cloud server. The target database can be a database of a container-based cluster management platform (Kuberentes, k8s) deployed on the cloud server, such as etcd / apiServer. The k8s deployed on the cloud server provides a set of perception mechanisms for the database. The perception mechanism can enable the second edge node to perceive the address information change of the target database when the target download address information is saved in the target database.

[0062] Exemplarily, saving the target download address information to the target database may be modifying the address information of a preset location in a file of a preset category in the target database into the target download address information, wherein the file of the preset category may be a yaml file.

[0063] S130. The cloud server sends target download address information to the second edge node, where the second edge node is an edge node on the user side, so that the second edge node pulls the distribution function from the first edge node according to the target download address information.

[0064] In the disclosed embodiment, after saving the target download address information, the cloud server sends the target download address information to the second edge node, which is an edge node on the user side, so that the second edge node pulls the distribution function from the first edge node according to the target download address information.

[0065] Specifically, after the cloud server distributes the distribution function to the first edge node, the first edge node generates target download address information corresponding to the distribution function based on the distribution function, and sends the target download address information to the cloud server through the network. The cloud server then obtains the target download address information corresponding to the distribution function returned by the first edge node, saves the target download address information to the target database, and then sends the target download address information to the second edge node through the network, so that the second edge node pulls the distribution function from the first edge node according to the target download address information.

[0066] In the disclosed embodiment, a distribution function can be sent to a first edge node through a cloud server, and the first edge node is an edge node corresponding to an Internet data center. Furthermore, after the cloud server sends the distribution function to the first edge node, the target download address information corresponding to the distribution function sent by the first edge node is received, and the target download address information is saved, and the target download address information is sent to a second edge node, and the second edge node is an edge node on the user side, so that the second edge node can pull the distribution function from the first edge node according to the target download address information. Thus, the target download address information sent by the first edge node can be received through the cloud server, and the target download address information can be sent to the second edge node, so that the second edge node can pull the distribution function from the first edge node to the local disk according to the target download address information, thereby reducing the time and resource consumption of function distribution, and improving the user experience.

[0067] Based on the above-mentioned embodiments of the present disclosure, the cloud server sends the distribution function to the first edge node in S110, which may specifically include: the cloud server compresses and encrypts the distribution function to obtain an encrypted compressed package corresponding to the distribution function; and sends the compressed package to the first edge node.

[0068] In the embodiments of the present disclosure, the encryption process may adopt a symmetric key encryption method or other existing encryption methods.

[0069] Specifically, after receiving the distribution function, the cloud server can compress and encrypt the distribution function based on a preset code program such as the fass controller service of the cloud server, obtain an encrypted compressed package corresponding to the distribution function, store the encrypted compressed package and distribute it to the first edge node.

[0070] In the embodiment of the present disclosure, after receiving the distribution function, the distribution function can be encrypted based on a preset code program to obtain an encrypted compressed package corresponding to the distribution function, and the encrypted compressed package can be distributed to the first edge node, thereby improving the security of the distribution function during the distribution process.

[0071] In the embodiment of the present disclosure, before the cloud server compresses and encrypts the distribution function, the function distribution method may also include: the cloud server compiles the distribution function based on a preset code program to obtain a compiled target binary distribution function, wherein the preset code program is used to receive the distribution function and compile the distribution function, and the compiled distribution function is the target binary programming language under the cloud server platform.

[0072] In the disclosed embodiment, since the distribution function is a high-level programming language, it is necessary to compile the distribution function into a low-level programming language that can be recognized by the cloud server.

[0073] The cloud server platform can be understood as the operating system of the cloud server, such as the Linux operating system.

[0074] The target binary programming language may be a wasm binary programming language. In the embodiment of the present disclosure, wasm may be understood as a lightweight virtual machine in the second edge node.

[0075] Furthermore, the compiled target binary distribution function is encrypted to obtain a compressed package corresponding to the compiled target binary distribution function, and the compressed package corresponding to the compiled target binary distribution function is distributed to the first edge node.

[0076] The target binary distribution function includes a distribution function executable by the lightweight virtual machine.

[0077] In the embodiment of the present disclosure, after receiving the distribution function, the distribution function can be compiled, and the compiled distribution function can be compressed and encrypted. The distribution function will be distributed to the first edge node only after the encryption process. In this way, while ensuring the security of the distribution function during the distribution process, it can provide a basis for the subsequent loading of the distribution function, thereby improving the loading rate and further improving the function distribution rate.

[0078] In an embodiment of the present disclosure, when there are at least two versions corresponding to the distribution function, the distribution functions corresponding to the at least two versions are distributed to the first edge node; the cloud server receives the download address information corresponding to the at least two versions sent by the first edge node, and saves the download address information corresponding to the at least two versions into the target database.

[0079] Specifically, when there are at least two versions corresponding to the distribution function, the cloud server distributes the distribution functions corresponding to the at least two versions to the first edge node. After receiving the distribution functions corresponding to the at least two versions, the first edge node generates download address information corresponding to the at least two versions of the distribution functions, and returns it to the cloud server. Then, the cloud server obtains the download address information corresponding to the at least two versions returned by the first edge node, saves the download address information corresponding to the at least two versions in the target database, and sends the download address information corresponding to the at least two versions to the second edge node, so that the second edge node pulls different versions of the distribution function from the first edge node based on the download address information corresponding to the at least two versions.

[0080] The specific implementation of saving the download address information corresponding to at least two versions into the target database is similar to the implementation of saving the target download address information into the target database in the above embodiment, and will not be described in detail here.

[0081] In the disclosed embodiment, when there are at least two versions corresponding to a distribution function, the cloud server distributes the distribution functions corresponding to the at least two versions to the first edge node, and the first edge node generates download address information corresponding to the at least two versions of the distribution functions, and returns it to the cloud server. The cloud server then obtains the download address information corresponding to the at least two versions returned by the first edge node, saves the download address information corresponding to the at least two versions in a target database, and sends the download address information corresponding to the at least two versions to the second edge node, so that the second edge node pulls different versions of the distribution function from the first edge node based on the download address information corresponding to the at least two versions. As a result, when distributing the function, the version information of the distribution function can be taken into consideration to achieve the technical effect of grayscale distribution.

[0082] Figure 3 is a flowchart of another function distribution method provided by an embodiment of the present disclosure, such as Figure 3 As shown, the function distribution method includes the following steps:

[0083] S310: The cloud server receives the distribution function, compiles the distribution function based on a preset code program, and obtains a compiled target binary distribution function.

[0084] S320: Encrypt the compiled target binary distribution function to obtain a compressed package corresponding to the target binary distribution function, and distribute the compressed package corresponding to the target binary distribution function to the first edge node.

[0085] S330. The cloud server receives the target download address information corresponding to the distribution function sent by the first edge node, saves the target download address information to the target database, and then sends the target download address information to the second edge node.

[0086] It should be noted that the specific implementation of steps S310-S330 is similar to that in the above embodiment and will not be described in detail here.

[0087] In the disclosed embodiment, a distribution function can be received through a cloud server, and the distribution function is compiled based on a preset code program to obtain a compiled target binary distribution function, and the compiled target binary distribution function is encrypted to obtain a compressed package corresponding to the target binary distribution function, and the compressed package corresponding to the target binary distribution function is distributed to a first edge node. The cloud server obtains the target download address information corresponding to the distribution function returned by the first edge node, and after saving the target download address information to a target database, the target download address information is sent to a second edge node, so that the second edge node pulls the distribution function from the first edge node according to the target download address information. Thus, the security of the distribution function is ensured based on the encryption processing during the function distribution process, and at the same time, a basis is provided for the subsequent loading of the distribution function based on the compilation processing, thereby improving the loading rate, further improving the function distribution rate, reducing the time and resource consumption of function distribution, and improving the user experience.

[0088] Figure 4 is a flowchart of another function distribution method provided by an embodiment of the present disclosure, such as Figure 4 The function distribution method shown can be based on Figure 2 The second edge node 23 in the embodiment is executed, such as Figure 4 As shown, the function distribution method includes the following steps:

[0089] S410. The second edge node receives the target download address information sent by the cloud server. The target download address information is generated by the first edge node after the cloud server sends the distribution function to the first edge node. The first edge node is the edge node corresponding to the Internet data center.

[0090] In the disclosed embodiment, the second edge node can receive the target download address information sent by the cloud server based on a preset agent program, wherein the preset agent program is a pre-set program for receiving the target download address information sent by the cloud server, such as the rt Engine agent program set by the second edge node. It can also be understood that the preset agent program has the function of subscribing to the update of files of preset categories in the target database, wherein the files of the preset categories can be yaml files, and once the address information of the yaml files in the target database is updated, the preset agent program can perceive it.

[0091] S420: The second edge node pulls the distribution function from the first edge node according to the target download address information, where the second edge node is an edge node on the user side.

[0092] In the embodiment of the present disclosure, after receiving the target download address information, the second edge node pulls the distribution function from the first edge node according to the target download address information.

[0093] Specifically, after receiving the target download address information, the second edge node pulls the distribution function from the first edge node based on the target download address information based on the preset agent program, decrypts the distribution function, and then decompresses and stores it in the local disk of the second edge node.

[0094] The preset agent program also has the function of determining the version corresponding to the distribution function to be pulled.

[0095] In some embodiments of the present disclosure, when there are at least two versions of a distribution function, the cloud server will distribute the distribution functions corresponding to the at least two versions to the first edge node, and the first edge node will generate download address information corresponding to the distribution functions corresponding to the at least two versions, and return it to the cloud server, so that the cloud server saves the download address information corresponding to the distribution functions corresponding to the at least two versions to the target database, and sends the distribution functions corresponding to the at least two versions to the second edge node, so that the second edge node receives the download address information corresponding to the distribution functions corresponding to the at least two versions sent by the cloud server based on a preset agent program, and determines the version of the distribution function to be pulled by the second edge node based on the preset agent program, and then pulls the distribution function corresponding to the version to be pulled from the first edge node based on the download address information of the distribution function corresponding to the version to be pulled.

[0096] In the disclosed embodiment, the target download address information sent by the cloud server can be received through the second edge node. The target download address information is generated by the first edge node after the cloud server receives the distribution function and distributes the distribution function to the first edge node. The first edge node is the edge node corresponding to the Internet data center. After receiving the target download address information, the second edge node pulls the distribution function from the first edge node according to the target download address information. The second edge node is an edge node on the user side. Therefore, by receiving the target download address information sent by the cloud server and pulling the distribution function from the first edge node to the local disk according to the target download address information, the time and resource consumption of function distribution are reduced, and the user experience is improved. At the same time, when the distribution function corresponds to at least two versions, the technical effect of reply distribution is achieved.

[0097] Further, in Figure 4 Based on the function distribution method shown, after S420, the function distribution method may also include: the second edge node receives a data acquisition request sent by the user end; the lightweight virtual machine runtime in the second edge node obtains the target distribution function corresponding to the data acquisition request from the second edge node; the lightweight virtual machine runtime in the second edge node executes the target distribution function, and feeds back the execution result to the user end.

[0098] After the second edge node receives the data acquisition request sent by the user end, it shakes hands with the user end to establish a connection, and at the same time triggers the lightweight virtual machine runtime in the second edge node to load the target distribution function corresponding to the data acquisition request from the local disk of the second edge node to the memory of the runtime; sends the data acquisition request to the lightweight virtual machine runtime, so that the lightweight virtual machine runtime executes the target distribution function, and feeds back the execution result to the user end.

[0099] The data acquisition request may be an https request, which is not limited here.

[0100] In the embodiment of the present disclosure, after receiving the data acquisition request sent by the user end, the second edge node shakes hands with the user end to establish a connection. The specific implementation method is similar to the existing method of establishing a connection through handshake, and will not be repeated here.

[0101] In the embodiment of the present disclosure, the lightweight virtual machine runtime may be a wasm virtual machine runtime.

[0102] In an embodiment of the present disclosure, when there are multiple lightweight virtual machine runtimes, only any one of the multiple lightweight virtual machine runtimes can be triggered to load the target distribution function corresponding to the data acquisition request from the local disk of the second edge node into the runtime's memory.

[0103] Specifically, the second edge node receives the data acquisition request sent by the user end based on the edge entry gateway, and after receiving the data acquisition request sent by the user end, it shakes hands with the user end based on the edge entry gateway to establish a connection, and at the same time triggers the lightweight virtual machine runtime in the second edge node to load the target distribution function corresponding to the data acquisition request from the local disk of the second edge node to the memory of the lightweight virtual machine runtime, so that the lightweight virtual machine runtime executes the target distribution function and feeds back the execution result to the user end.

[0104] Among them, the edge entry gateway can be a pre-set httpproxy program.

[0105] In an embodiment of the present disclosure, before receiving a data acquisition request sent by a user terminal, the distribution function can be pulled to the local disk of the second edge node, and then after receiving the data acquisition request sent by the user terminal, while shaking hands with the user terminal to establish a connection, the lightweight virtual machine runtime in the second edge node is triggered to load the target distribution function corresponding to the data acquisition request from the local disk of the second edge node into the memory of the lightweight virtual machine runtime, and the data acquisition request is sent to the lightweight virtual machine runtime, so that the lightweight virtual machine runtime executes the target distribution function, and feeds back the execution result to the user terminal for direct triggering, thereby improving the speed of processing data acquisition requests.

[0106] In some embodiments of the present disclosure, when the second edge node includes multiple lightweight virtual machine runtimes, before executing the target distribution function through the lightweight virtual machine runtime in the second edge node, the function distribution method may also include: searching for a target lightweight virtual machine runtime that includes the target distribution function from the multiple lightweight virtual machine runtimes; and sending a data acquisition request to the target lightweight virtual machine runtime for executing the target distribution function through the target lightweight virtual machine.

[0107] Specifically, the second edge node may determine the target lightweight virtual machine runtime based on the saved record when the runtime loads the target distribution function.

[0108] Further, executing the target distribution function by the lightweight virtual machine runtime in the second edge node may specifically include: executing the target distribution function by the target lightweight virtual machine runtime.

[0109] In the embodiment of the present disclosure, when multiple lightweight virtual machine runtimes are included in the second edge node, a target lightweight virtual machine runtime containing a target distribution function can be searched from the multiple lightweight virtual machine runtimes, thereby ensuring that the data acquisition request can be accurately sent to the lightweight virtual machine runtime loaded with the target distribution function corresponding to the data acquisition request, thereby avoiding waste of resources.

[0110] In some embodiments of the present disclosure, a DNS server is deployed inside the second edge node. When the data acquisition request of the user terminal reaches the second edge node, the request processing corresponding to the data acquisition request is completed at the second edge node, such as DNS resolution, etc., to ensure the delay.

[0111] In some other embodiments of the present disclosure, developers can realize automatic scaling of the second edge node by setting preset scaling codes, and then realize the addition and deletion of the second edge node, including initialization of the second edge node, installation of the application, etc., so as to achieve more effective scaling scenarios after the second edge node is linked to the public domain name.
