[0046] The embodiments of the present invention have the following advantages:

[0047] In this embodiment of the invention, a content delivery network may include edge nodes, parent nodes communicating with the edge nodes, and origin stations communicating with the parent nodes. During a client's content request process, the edge node obtains the content request sent by the client, determines the file information corresponding to the content request, and if the file information meets the conditions, generates a fragment request corresponding to the content request. Then, the parent node obtains the resource address corresponding to the content request from the origin station based on the fragment request, sends the fragment request to the origin station based on the resource address, receives the fragment file content corresponding to the fragment request sent by the origin station, and then the edge node receives the fragment file content sent by the parent node. The system retrieves the resource address and requests the corresponding target file content from the parent node based on the resource address. During content distribution, after the parent node initially requests the resource address from the origin server, it sends the resource address to the edge node for storage. With the implementation of fragmented content retrieval, in subsequent content distribution processes, the edge node can request the corresponding content from the parent node based on the recorded resource address. The parent node can then retrieve the corresponding content based on the resource address and return it. This effectively reduces the response operations between the parent node and the origin server, reduces the resource consumption of the node machine, and improves the single-point concurrency capability.

[0050] Figure 3 This is a block diagram of an electronic device provided in an embodiment of the present invention. Detailed Implementation

[0051] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] As an example, the principle of a Content Delivery Network (CDN) is to use nodes at various levels of the CDN to cache resources from the origin server to nodes located near the customer's geographical location or with fast network access speeds. This allows customers to directly access resources from the nearest location, thereby improving access speed, reducing access pressure on the origin server, and optimizing the customer experience.

[0053] Optimization for hybrid scenarios involving shard requests and 302 redirect responses under CDN networks:

[0054] (1) CDN hierarchical sharding request

[0055] Currently, mainstream CDN providers all adopt a tiered deployment approach for their CDN nodes.

[0056] In other words, if the client requests an edge node and there is no cache on the edge node, it requests a parent node. If there is no cache on the parent node, it retrieves the cache from the client's origin server.

[0057] When requesting large files, it's crucial to minimize origin-fetching traffic and maximize hit rate while correctly responding to client requests. This is typically achieved through sharded storage. Specifically, when a large file request reaches a CDN edge node, the edge node splits the request into several fixed-size range requests. For example, if the requested file size is 100MB and each shard is set to 1MB, the edge node will split it into 100 shard requests (0-1MB, 1-2MB, ..., 99MB-100MB) and send them to the parent node. From the parent node's perspective, these 100 shard requests are independent and unrelated to each other.

[0058] (2) 302 Redirect Response

[0059] To improve the flexibility of response content, the client's origin server will use a 302 redirect to respond to client requests. Specifically, after the CDN parent node initiates a request back to the origin server, the origin server responds to the parent node with a 302 response and an appended Location header. The CDN parent node parses the Location header to obtain the final real URL (Uniform Resource Locator), and then initiates a second request to the real URL, receiving a 200 response from the origin server and obtaining the actual target file. In other words, under these conditions, for each client request, the CDN node needs to initiate two back-to-origin requests (one redirect response and one response containing the actual content).

[0060] For a scenario combining (1) and (2), each shard request requires two origin requests. For a 100M file with a 1M shard size, the cache is divided into 100 shards, and each shard request requires two requests. Therefore, for this file, 200 requests need to be sent to the origin server. This scenario has a drawback: for each shard request on the parent layer, a duplicate 302 redirect request needs to be sent, resulting in resource consumption of the node machine, reducing the single-point concurrent service capability, and increasing the origin bandwidth cost. If the origin 302 redirect requests are to be merged, the Location header information between independent shard requests needs to be shared on the parent node. Since each shard request is independent for the CDN parent node and the data structure is stored separately, if information between requests needs to be shared, the program needs to set up shared memory and lock the shared memory, which will cause a lot of additional performance loss. Therefore, the above solution also has a drawback.

[0061] One of the core inventive points of this invention is that during content distribution, edge nodes obtain content requests sent by clients, determine the file information corresponding to the content requests, and if the file information meets the conditions, generate a fragment request corresponding to the content requests. Then, the parent node obtains the resource address corresponding to the content requests from the origin server according to the fragment requests, and sends the fragment requests to the origin server according to the resource addresses. It also receives the fragment file content corresponding to the fragment requests sent by the origin server. Then, the edge node receives the fragment file content and resource addresses sent by the parent node, and requests the target file content corresponding to the content requests from the parent node according to the resource addresses. Thus, during content distribution, after the parent node requests the resource address from the origin server for the first time, it sends the resource address to the edge node for storage. With the fragment content acquisition achieved, in subsequent content distribution processes, the edge node can request the corresponding content from the parent node based on the recorded resource addresses. For the parent node, it can request the corresponding content based on the resource addresses and return it, effectively reducing the response operations between the parent node and the origin server, reducing the resource consumption of the node machines, and improving the single-point concurrency capability.

[0062] Reference Figure 1 This diagram illustrates a flowchart of a content distribution processing method provided in an embodiment of the present invention, applied to a content distribution network. The content distribution network includes at least edge nodes, parent nodes communicating with the edge nodes, and source stations communicating with the parent nodes. Specifically, it may include the following steps:

[0063] Step 101: The edge node obtains the content request sent by the client, determines the file information corresponding to the content request, and if the file information meets the conditions, generates a fragmentation request corresponding to the content request.

[0064] Optionally, an edge cloud can consist of edge nodes, parent nodes, and an origin server. Edge nodes can be direct nodes communicating with user terminals, parent nodes can be nodes communicating with edge nodes (such as central nodes), and the origin server can be a resource repository for storing relevant data. During content distribution, edge nodes can receive requests from clients or user terminals and forward them to parent nodes. The parent nodes then retrieve the relevant data from the origin server and return it to the edge nodes, which in turn forward it to the clients or user terminals.

[0065] In this embodiment of the invention, for files that are not cached in the CDN network, the client can send a corresponding content request to the edge node to obtain the corresponding file content. Specifically, the edge node can obtain the content request sent by the client, determine the file information corresponding to the content request, and then determine whether the file information needs to be fragmented. If so, it can generate a fragment request corresponding to the content request to obtain the corresponding file content from the parent node through the fragment request.

[0066] In the specific implementation, the edge node can obtain the content request sent by the client, determine the target file content corresponding to the content request, and obtain the file memory corresponding to the target file content. If the file memory is greater than or equal to a preset memory threshold, it is divided according to the file memory to generate several fragment requests corresponding to the content request. If the file memory is less than the preset memory threshold, the content request can be directly sent to the parent node. The parent node retrieves the file content from the origin. The origin server can respond with a status code 302 and inform the parent node of the corresponding URL address through the Location response header. Then, the parent node parses the Location response header, initiates a request to the origin server for the URL address, and obtains the file content sent by the origin server after a 200 or 206 response. Finally, the file content is returned to the edge node.

[0067] For example, for a request for a 100MB file with a 1MB chunk size, the cache can divide it into 100 chunks. Edge nodes can generate 100 chunk requests and then use these 100 chunk requests to retrieve the corresponding chunk file content from the parent node. Specifically, when the file content for a content request needs to be retrieved via chunks, after generating the corresponding chunk requests, the edge node can first send the first chunk request to the parent node. This allows the parent node to retrieve the corresponding resource address from the origin server using the first chunk request, thereby reducing redundant retrieval processes based on the retrieved resource address.

[0068] Step 102: The parent node obtains the resource address corresponding to the content request from the origin server according to the sharding request, sends the sharding request to the origin server according to the resource address, and receives the sharded file content corresponding to the sharding request sent by the origin server.

[0069] In this embodiment of the invention, after receiving a sharding request from an edge node, the parent node can retrieve the file content from the origin based on the sharding request. Correspondingly, the origin server can respond with status code 302 and inform the parent node of the actual URL address (resource address) through the Location response header. The parent node can send the corresponding sharding request to the origin server through the resource address to obtain the sharding content corresponding to the sharding request. The origin server can extract the corresponding sharding file content according to the sharding request and return the sharding file content to the parent node, so that the parent node can return the sharding file content to the edge node.

[0070] In the specific implementation, for file content that needs to be obtained through fragmentation, the parent node can first send the first fragmentation request to the origin server and receive the response header sent by the origin server for the first fragmentation request. The response header includes the resource address corresponding to the content request. Then, it sends the first resource acquisition request for the resource address to the origin server and receives the first fragmented file content corresponding to the first resource acquisition request sent by the origin server. Simultaneously, the parent node can return the acquired resource address along with the content of the first shard file to the edge node. The edge node receives the content of the first shard file corresponding to the first shard request and the resource address corresponding to the content request returned by the parent node. At the same time, the edge node returns the content of the first shard file to the client. Thus, when obtaining the shard content corresponding to the first shard request, the parent node sends the acquired resource address to the edge node, and the edge node records the resource address. This allows the shard file content corresponding to the remaining shard requests to be obtained based on the resource address, reducing the process of the parent node repeatedly obtaining resource addresses from the origin server. This effectively reduces the response operations between the parent node and the origin server, reduces the resource consumption of the node machine, and improves the single-point concurrency capability.

[0071] Step 103: The edge node receives the fragmented file content and the resource address sent by the parent node, and requests the target file content corresponding to the content request from the parent node according to the resource address.

[0072] In this embodiment of the invention, after receiving the fragmented file content and resource address sent by the parent node, the edge node can, on the one hand, return the obtained fragmented file content to the client, and on the other hand, request the fragmented file content corresponding to other fragmented requests from the parent node based on the resource address, thereby obtaining all file content requested by the content request. Thus, during the content distribution process, after the parent node requests the resource address from the origin server for the first time, it sends the resource address to the edge node for storage. With the fragmented content acquisition achieved, in subsequent content distribution processes, the edge node can request the corresponding content from the parent node based on the recorded resource address. The parent node can then request the corresponding content based on the resource address and return it, effectively reducing the response operations between the parent node and the origin server, reducing the resource consumption of the node machine, and improving the single-point concurrency capability.

[0073] In the specific implementation, when the file content to be obtained needs to be retrieved through multiple shard requests, after obtaining the resource address through the first shard request, the edge node can sequentially send the remaining shard requests (excluding the first shard request) and their resource addresses to the parent node in the order they correspond. The parent node can then sequentially send a second resource retrieval request for the resource address to the origin server and sequentially receive the second shard content corresponding to the second resource retrieval request from the origin server. The parent node then sends the second shard content to the edge node. Thus, when the file content corresponding to the content request needs to be obtained through N shard requests, the corresponding resource address can be obtained through the first shard request. Then, for the remaining shard requests, the parent node can obtain the corresponding file content through the resource address recorded by the edge node. This reduces the number of interactions with the origin server to obtain the resource address by N-1 times, effectively reducing the response operations between the parent node and the origin server, reducing the resource consumption of the node machine, and improving the single-point concurrency capability.

[0074] It should be noted that the embodiments of the present invention include, but are not limited to, the examples described above. It is understood that those skilled in the art can make further settings according to actual needs under the guidance of the ideas in the embodiments of the present invention, and the present invention does not limit such settings.

[0075] In this embodiment of the invention, a content delivery network may include edge nodes, parent nodes communicating with the edge nodes, and origin stations communicating with the parent nodes. During a client's content request process, the edge node obtains the content request sent by the client, determines the file information corresponding to the content request, and if the file information meets the conditions, generates a fragment request corresponding to the content request. Then, the parent node obtains the resource address corresponding to the content request from the origin station based on the fragment request, sends the fragment request to the origin station based on the resource address, receives the fragment file content corresponding to the fragment request sent by the origin station, and then the edge node receives the fragment file content sent by the parent node. The system retrieves the resource address and requests the corresponding target file content from the parent node based on the resource address. During content distribution, after the parent node initially requests the resource address from the origin server, it sends the resource address to the edge node for storage. With the implementation of fragmented content retrieval, in subsequent content distribution processes, the edge node can request the corresponding content from the parent node based on the recorded resource address. The parent node can then retrieve the corresponding content based on the resource address and return it. This effectively reduces the response operations between the parent node and the origin server, reduces the resource consumption of the node machine, and improves the single-point concurrency capability.

[0076] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, an example is provided below for illustration:

[0077] By using request header passing between CDN edge nodes and parent nodes, the aim is to merge duplicate 302 responses caused by parent sharding requests, thereby improving node service capabilities, saving origin bandwidth, and enhancing single-point performance. The specific process includes:

[0078] For file requests that are not cached in the CDN network, after receiving the client request, the edge node determines that the request needs to be sharded and initiates the first sharding request to the parent node.

[0079] After receiving the first shard request, the parent node retrieves the first shard content of the file from the origin server. At this time, the origin server responds with a status code of 302 and informs the parent node of the real URL address through the Location response header.

[0080] The parent node parses the Location response header, sends a request to the origin server for the actual URL, receives a 200 or 206 response from the origin server, and obtains the actual file content.

[0081] The parent node responds to the edge node with the actual file, and at the same time brings the contents of the Location header from the 302 redirect response from the origin server to the edge node.

[0082] In the response to the first shard request at the edge node, the Location header content of the origin server is also obtained. This information is then carried in the request headers of subsequent shard requests and sent to the parent layer. The parent layer uses this information to obtain the final, real URL of the request, skipping the 302 response process from the origin server and directly requesting the actual URL.

[0083] Through the above process, after the first shard request on the CDN parent node receives a 302 redirect response, it records the real URL specified in the Location header of the response and sends it to the edge node. The CDN edge node records the real URL and passes it to the CDN parent node through the request header when requesting subsequent shards. The parent node then directly initiates a request to the real URL. In this optimized scenario, for a request containing N shards, the number of origin pulls can be reduced by N-1 compared to the original solution.

[0084] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.

Specifically, user input unit 307 includes a touch panel 3071 and other input devices 3072. Touch panel 3071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 3071). Touch panel 3071 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 310, which receives and executes commands from the processor 310. In addition, touch panel 3071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to touch panel 3071, user input unit 307 may also include other input devices 3072. Specifically, other input devices 3072 may include, but are not limited to, physical keyboards, function keys (such as volume control buttons, power buttons, etc.), trackballs, mice, joysticks, etc., which will not be described in detail here.

[0116] Furthermore, the touch panel 3071 can cover the display panel 3061. When the touch panel 3071 detects a touch operation on or near it, it transmits the information to the processor 310 to determine the type of touch event. Subsequently, the processor 310 provides corresponding visual output on the display panel 3061 according to the type of touch event. It is understood that in one embodiment, the touch panel 3071 and the display panel 3061 are implemented as two independent components to realize the input and output functions of the electronic device.

The processor 310 may include one or more processing units; preferably, the processor 310 may integrate an application processor and a modem processor. The application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 310.

[0120] The electronic device 300 may also include a power supply 311 (such as a battery) for supplying power to various components. Preferably, the power supply 311 can be logically connected to the processor 310 through a power management system, thereby enabling functions such as managing charging, discharging, and power consumption through the power management system.
