Description

Technical Field

[0001] This application relates to the field of resource acquisition, and more particularly to a method and apparatus for acquiring resources based on a content delivery network. Background Technology

[0002] A Content Delivery Network (CDN) is a distributed network built on top of an existing network to speed up network access.

[0003] In general, to save costs and reduce disk usage, files are typically stored only once on a single CDN node (multiple servers). In this scenario, if a file experiences a sudden surge in requests—this file is called a "hot file"—all requests will concentrate on the server storing the hot file. This server will become the bottleneck for the entire CDN node, causing service issues.

[0004] In existing technologies, to enable faster access to frequently accessed files, these files are typically distributed across multiple servers on different nodes. However, this method requires the support of an upstream CDN scheduler, a task distribution notification service, and a task distribution execution service (file downloader). When multiple upstream services need to coordinate and cooperate, efficiency losses can easily occur. Furthermore, in real-time events or when a file suddenly becomes a frequently accessed file, server performance and network anomalies can easily result. Summary of the Invention

[0005] In view of this, this application provides a resource acquisition method and apparatus based on a content delivery network, which avoids server performance and network anomalies caused by real-time events or sudden changes from cold files to hot files, thereby improving the resource acquisition efficiency of the content delivery network.

[0009] The resource information of the first hot resource is sent to the second resource node so that the second resource node can obtain the first hot resource based on the resource information of the first hot resource.

[0010] When a resource acquisition request for the first hot resource is received from a client, a temporary redirect address for the first hot resource is returned to the client. The temporary redirect address is used by the client to acquire the first hot resource from the second resource node.

[0016] The hot resource information set is multicast in the content delivery network so that the second resource node can obtain the resource information of the first hot resource based on the hot resource information set.

[0017] Optionally, when a resource acquisition request for the first hot resource is received from a client, returning the temporary redirect address of the first hot resource to the client includes:

[0018] When a resource acquisition request for the first hot resource is received from a client, it is determined whether the first hot resource meets a preset resource jump threshold based on the historical resource acquisition requests. The preset resource jump threshold includes the fact that the resource acquisition frequency meets a preset condition within a preset period.

[0019] When the first hot resource meets the preset resource redirection threshold, the temporary redirection address of the first hot resource is returned to the client.

[0020] Optionally, the method further includes:

[0024] Optionally, obtaining the second hotspot resource based on its resource information includes:

[0025] The second hot resource is obtained based on its resource information, and then stored in a memory disk.

[0026] Optionally, the method further includes:

[0027] When it is determined from the node service log that the second hot resource no longer meets the preset hot resource conditions, the second hot resource is deleted from the memory disk.

[0028] Based on the same inventive concept, in a second aspect, embodiments of this application provide a resource acquisition device based on a content delivery network, the device comprising:

[0029] The resource determination module is used to determine the primary hot resource based on the real-time logs of the node service.

When a resource acquisition request for the first hot resource is received from a client, a temporary redirect address for the first hot resource is returned to the client. This temporary redirect address is used by the client to acquire the first hot resource from the second resource node. Therefore, resource nodes send the resource information of hot resources within their own nodes to other resource nodes.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] To avoid server performance and network anomalies caused by real-time events or sudden changes in file usage from cold to hot, and to improve the resource acquisition efficiency of the content delivery network (CDN), this application provides a resource acquisition method based on the CDN. This method can be applied to a first resource node in the CDN, and the first resource node can be any resource node in the CDN. Please refer to [link to relevant documentation]. Figure 1 The method may include:

[0043] Step S100: Determine the first hot resource based on the real-time logs of the node service.

[0044] The first resource node determines the first hot resource based on the real-time logs of its own node services.

[0045] Specifically, the process by which the first resource node determines the first hot resource based on the real-time logs of its node service may include: obtaining the real-time logs of the first resource node's node service, which include historical resource acquisition requests; and determining the first hot resource based on the historical resource acquisition requests and preset hot resource conditions, which include the resource acquisition frequency meeting preset conditions.

[0046] In practical applications, the first resource node can track and analyze the real-time logs of its own node service, obtain the URLs in the real-time logs of the node service to extract the file names accessed by users, calculate and analyze the number of requests for each file within a preset time period according to the file names, identify the files whose number of requests within the preset time period meets the preset conditions as hot resources, and record the information of hot resources in the local database.

[0047] It should be noted that no preset conditions are limited in this embodiment. Those skilled in the art can choose as needed. As an example, the preset condition is set to more than 60 times per minute. When the frequency of resource acquisition meets the requirement of more than 60 times per minute, the file is identified as a hot file.

[0048] Step S200: Send the resource information of the first hot resource to the second resource node so that the second resource node can obtain the first hot resource based on the resource information of the first hot resource.

[0049] The second resource node is any resource node in the content delivery network other than the first resource node. The second resource node can obtain the first hot resource based on its resource information.

[0050] In practical applications, the first resource node can send the resource information corresponding to the first hot resource to the second resource node after determining the first hot resource, or it can send the resource information corresponding to all hot resources determined within a preset time period to the second resource node. This application embodiment does not limit this.

[0051] Specifically, the first resource node sends the resource information of the first hot resource to the second resource node, which may include:

[0052] The resource information of the first hot resource is determined based on the first hot resource, and a hot resource information set is generated based on the resource information of the first hot resource; the hot resource information set is multicast and published in the content delivery network so that the second resource node can use the resource information of the first hot resource based on the hot resource information set.

[0053] In practical applications, after the first resource node determines the first hot resource, it can determine the resource information of the first hot resource based on the first hot resource. It can be understood that the resource information of the first hot resource is used to indicate the first hot resource information and the storage location of the first hot resource in the content delivery network. For example, the resource information of the first hot resource may include the name of the first hot resource, the size of the first hot resource, the IP address of the first resource node, and other information.

[0054] The first resource node generates a hot resource information set based on the resource information of the first hot resource, and multicasts the hot resource information set in the content delivery network to announce the resource information of the hot resource to the second resource node.

[0055] As an optional implementation, the first resource node can also encapsulate a hot resource JSON list based on the determined first hot resource, and the hot resource JSON list includes the resource information of the first hot resource.

[0056] It is understandable that a resource node may contain multiple hot resources. The first resource node encapsulates these hot resources into a JSON list, which facilitates the sharing of hot resources among resource nodes. For example, the JSON list of hot resources can look like this:

[0057]

[0058] As an optional implementation, the first resource node can multicast the distribution of hot resource information sets using the following multicast protocol format, taking multicast from the first resource node to the second resource node as an example:

[0059] First resource node IP address Second resource node IP address User Datagram Protocol (UDP) User Datagram Protocol (UDP) checksum First resource node name Communication data (JSON list of hot resources)

[0060] The first resource node name is used to distinguish each resource node; the second resource node IP address can be obtained from a pre-configured multicast address library, which includes the addresses of each resource node in the content delivery network.

[0061] Step S300: When a resource acquisition request for obtaining the first hot resource is received from the client, the temporary redirect address of the first hot resource is returned to the client. The temporary redirect address is used by the client to obtain the first hot resource from the second resource node.

[0062] Specifically, when the first resource node receives a resource acquisition request from the client to obtain the first hot resource, it no longer provides the first hot resource to the client itself. Instead, it provides the client with a temporary redirect address for the first hot resource, so that the client can obtain the first hot resource from the second resource node based on the temporary redirect address.

[0063] It should be noted that temporary redirect addresses can include the HTTP 302 Found redirect status code. The HTTP 302 Found redirect status code indicates that the requested resource has been temporarily moved to the URL specified by the Location header of the HTTP response. The client will be redirected to this URL, but the search engine will not update the link to the resource. 302 Found is a status code in the Hypertext Transfer Protocol (HTTP).

[0064] It is understood that in this embodiment of the application, the transfer of the request to obtain hot resources is realized by the temporary redirect address of hot resources. It does not require the support of the upstream CDN scheduler and can be achieved by the HTTP 302 Found redirect status code. It can respond quickly and efficiently to situations that occur in real time or when a cold file suddenly becomes a hot file.

[0065] In an optional implementation, step S300 further includes: when a resource acquisition request for acquiring a first hot resource is received from a client, determining whether the first hot resource meets a preset resource jump threshold based on historical resource acquisition requests, wherein the preset resource jump threshold includes the resource acquisition frequency meeting a preset condition within a preset period; when the first hot resource meets the preset resource jump threshold, returning the temporary jump address of the first hot resource to the client.

[0066] Specifically, before returning the temporary redirect address of the first hot resource to the client, the first resource node can further determine whether the first hot resource meets the preset resource redirection threshold based on historical resource acquisition requests. If it does, it will then return the temporary redirect address of the first hot resource to the client.

[0067] The preset resource jump threshold can be defined as the resource acquisition frequency meeting preset conditions within a preset period. This application does not limit the preset period or preset conditions. As an example, the preset period is set to 120 seconds, and the preset requirement is set to more than 60 times per minute. That is, if the first hot resource meets the acquisition frequency requirement of more than 60 times for two consecutive minutes, then the first hot resource is determined to meet the preset resource jump threshold.

[0068] It is understood that, by further determining whether the first hot resource meets the jump threshold, i.e., by determining for the second time whether a jump operation is needed for the acquisition request of the first hot resource, unnecessary jump operations caused by the resource being falsely hot can be avoided, thus ensuring the effectiveness of the system logic.

[0069] As an optional implementation, in this embodiment, a separate service process can be set up in the first resource node for determining hot resources, sending resource information about hot resources, and acquiring hot resources. Therefore, by using an independent service process to handle the determination of hot resources, the sending of resource information about hot resources, and the acquisition of hot resources, it is possible to prevent the acquisition of hot resources from affecting the node service of the first resource node.

[0070] As an optional implementation, the method provided in this application embodiment may further include:

[0071] Receive resource information of the second hot resource broadcast by the second resource node; obtain the second hot resource based on the resource information of the second hot resource; when a resource acquisition request is received from a client to obtain the second hot resource, provide the second hot resource to the client.

[0072] Understandably, the primary resource node can also receive resource information about hot resources from other resource nodes, retrieve the corresponding hot resources based on this information, and provide them to the client. By disseminating hot resources throughout the content delivery network, client requests for these resources are not concentrated on a single server in the network. This effectively improves the overall data throughput of CDN nodes without increasing costs, and allows for rapid and efficient responses to real-time events or sudden shifts from cold to hot files, preventing server performance and network anomalies.

[0073] As an optional implementation, in this embodiment, the first resource node stores the second hot resource in a memory disk.

[0074] Specifically, the first resource node receives resource information of the second hot resource broadcast by the second resource node, acquires the second hot resource based on the resource information, and stores the second hot resource in a memory disk. In this embodiment, the resource node stores the hot resources pulled from other resource nodes in the memory disk space. Because the data access efficiency of the memory disk space is high, it can efficiently and promptly respond to sudden increases in requests for hot resources. It can be understood that a memory disk refers to a space allocated by the operating system within the server's memory. As an example, in a Linux system, it is usually " / dev / shm", and its size can be set by the administrator as needed.

[0075] As an optional implementation, in this embodiment of the application, when the first resource node determines from the memory disk that the second hot resource no longer meets the preset hot resource conditions based on the node service log, the second hot resource is deleted.

[0076] Specifically, the first resource node will monitor whether the second hot resource maintains a high level of popularity based on its own node service logs. When the popularity of the second hot resource no longer meets the preset hot resource conditions or the preset hot resource period ends, the first resource node can delete the second hot resource from the memory disk to avoid invalid resource occupation.

[0077] The following is combined Figure 2 The process of the resource acquisition method based on a content delivery network provided in the embodiments of this application will be described.

[0078] First, the client sends a resource retrieval request to the first resource node in the content delivery network. Next, the first resource node determines whether the resource requested is a hot resource. If not, it directly provides the resource to the client. If so, it further determines whether the resource meets a preset resource redirection threshold. If the resource does not meet the preset threshold, the first resource node directly provides the resource to the client. If the resource meets the preset threshold, the first resource node sends a temporary redirection address to the client, allowing the client to retrieve the resource from other resource nodes in the content delivery network based on this temporary redirection address.

[0079] In summary, this application provides a resource acquisition method based on a content delivery network. This method is applied to a first resource node and includes: determining a first hot resource based on node service logs; sending the resource information of the first hot resource to a second resource node, enabling the second resource node to acquire the first hot resource based on the resource information; and when receiving a resource acquisition request from a client for the first hot resource, returning a temporary redirect address of the first hot resource to the client, whereby the temporary redirect address is used by the client to acquire the first hot resource from the second resource node. Therefore, resource nodes send the resource information of hot resources to other resource nodes, allowing other resource nodes to pull the hot resource and provide it to the client, avoiding server performance and network anomalies in real-time events or when a cold file suddenly becomes a hot file, thus improving the resource acquisition efficiency of the content delivery network.

[0080] Corresponding to the above methods, this application also provides a resource acquisition device based on a content delivery network. Please refer to [link to relevant documentation]. Figure 3 The diagram shows the structure of the device, which may include:

[0098] In one optional embodiment, the device further includes:

[0099] The deletion module is used to delete the second hot resource from the random access memory (RAM) when it is determined from the node service log that the second hot resource no longer meets the preset hot resource conditions.
