Description

Technical Field

[0001] The present invention relates to the technical field of CDN networks, and in particular to a method, device, and electronic device for preheating data in a CDN network. Background Art

[0002] In a CDN (Content Delivery Network) network, the resource data accessed by the CDN network can be preheated first. Specifically, the resource data of the user is pushed from the source station of the CDN network to the edge nodes. When the resource data is accessed, the resource data can be directly provided from the edge nodes without going back to the source station to obtain it, which can improve the response speed of resource access.

[0003] In related technologies, preheating is usually triggered actively by users. After a user initiates a preheating request, the preheating request is cached in a preheating queue, and then the preheating request is queued and responded to according to a certain rule to perform related preheating operations. The preheating process usually requires occupying the network bandwidth resources of the CDN network and the request processing resources of the source station. When users actively trigger preheating, in most cases, the amount of resource data to be preheated is large. At this time, it is easy to affect the normal operation of the CDN network and cause the service of the CDN network to be unstable. In addition, during the preheating process, affected by factors such as CDN network fluctuations, limited processing capabilities of the source station, and restrictions on preheated data volume and preheating bandwidth by CDN network service providers, it is easy for resource data not to be quickly preheated to the edge nodes, resulting in low preheating efficiency. Furthermore, a large number of back-to-source requests are caused. If the number of back-to-source requests exceeds the processing capacity of the source station, the source station may crash, further leading to the instability of the CDN network service.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0032] The CDN network is an intelligent virtual network built on top of the existing network. Relying on edge servers deployed in various locations, through functional modules such as load balancing, content distribution, and scheduling of the central platform, users can obtain the required content nearby, which can reduce network congestion and improve the user access response speed and hit rate. In the CDN network, the resource data accessed to the CDN network can be preheated first. Specifically, the resource data of the user is pushed from the source station of the CDN network to the edge nodes. When the resource data is accessed, the resource data can be directly provided from the edge nodes without having to return to the source station to obtain it, which can improve the response speed of resource access; at the same time, it can also relieve the pressure on the source station caused by the sudden increase in the return source traffic.

[0033] See Figure 1 In the schematic diagram of the resource acquisition process of the CDN network shown, the resource request sent by the client is scheduled to the CDN node device through the scheduling module. According to the order of the node devices, relevant resources are obtained from each node device in turn. If the relevant resources are stored in the node device, the relevant resources are directly returned to the client. If the relevant resources are not stored in the node device, the node device needs to obtain them from the source station.

[0034] In the related art, the preheating is usually triggered actively by the user. After the user initiates a preheating request, the preheating request is cached in the preheating queue, and then queued and responded to the preheating request according to certain rules to perform relevant preheating operations. The preheating process usually requires occupying the network bandwidth resources of the CDN network and the request processing resources of the source station. When the user actively triggers the preheating, in most cases, the amount of resource data to be preheated is large. At this time, it is easy to affect the normal operation of the CDN network and cause the service of the CDN network to be unstable. In addition, during the preheating process, affected by factors such as CDN network fluctuations, limited processing capacity of the source station, and restrictions on the preheating data volume and preheating bandwidth by the CDN network service provider, it is easy for the resource data not to be quickly preheated to the edge nodes, and the preheating efficiency is low, which further causes a large number of return source requests. If the number of return source requests exceeds the processing capacity of the source station, the source station may crash, further leading to the instability of the CDN network service.

[0035] Based on the above, a data preheating method, device, and electronic device for a CDN network provided by an embodiment of the present invention can be applied to the data preheating scenario in the CDN network or other scenarios that require data preheating.

[0036] To facilitate the understanding of this embodiment, first, a data preheating method for a CDN network disclosed in an embodiment of the present invention is introduced in detail. This method is applied to a device running a first preheating component; the first preheating component is communicatively connected to a second preheating component; the device running the first preheating component can be a node device in a container cluster or a device such as a computer.

[0037] As Figure 2 shown, the method includes the following steps:

[0038] Step S202, obtaining an initial message from a first message queue through a first preheating component; wherein, the initial message is pre-pushed to the first message queue by a CDN network origin server;

[0039] In the above-mentioned first preheating component, a consuming program can actively obtain the initial message from the first message queue; the above-mentioned initial message is used to indicate that the data (also called resources) existing in the origin server has changed, such as resource addition or resource update, etc.; the above-mentioned initial message may also include the storage container where the changed data is located. If the changed data needs to be preheated, the initial message may also contain a preheating flag indicating whether the changed data needs to be preheated. The above-mentioned first message queue can store the initial messages in the order of receipt until they are obtained by the consuming program in the first preheating component. The first message queue can be Kafka (a high-throughput distributed publish-subscribe message system that can process all action flow data of consumers in a website); it can also be ActiveMQ (Active Message Queue, an open-source message middleware), RabbitMQ (Rabbit Message Queue, an open-source message queue service software), RocketMQ (Rocket Message Queue, an open-source distributed message system), etc.

[0040] The above-mentioned CDN network is an intelligent virtual network built on the existing network. Relying on edge servers deployed everywhere, through functional modules such as load balancing, content distribution, and scheduling of the central platform, users can obtain the required content nearby, reducing network congestion and improving user access response speed and hit rate. The above-mentioned CDN network origin server has functions such as high availability, PB (PetaByte, a higher-level storage unit)-level storage, infinite scalability, and multi-region services, and can continuously and stably provide services externally. At the same time, when the data in the origin server changes, it will automatically push the initial message of the change to the first message queue, and the first preheating component will automatically subscribe to the topic in the first message queue. The above-mentioned CDN network origin server can include multiple distributed origin servers. In actual implementation, after the data in the CDN network origin server changes, it will automatically push the initial message of the data change to the first message queue. At this time, the consuming program of the first preheating component can actively obtain the initial message in the first message queue.

[0041] Step S204: Generate a warm-up message based on the initial message and send the warm-up message to the second warm-up component. The warm-up message is used to instruct the second warm-up component to notify a specified CDN network node to obtain the data to be preheated from the source station.

[0042] Generally, a CDN network includes multiple network nodes. Different network nodes need to obtain different data to be preheated, and the storage containers where different data to be preheated are located are different. The above initial message can be used to indicate that there is data to be preheated in the source station. Therefore, after obtaining the initial message, a warm-up message can be generated according to the storage container where the changed data included in the initial message is located. Additionally, if the initial message also includes a warm-up flag indicating whether the changed data needs to be preheated, a warm-up message can be jointly generated according to the storage container where the changed data included in the initial message is located and the warm-up flag, so that the warm-up message includes: a specified CDN network node and the storage container where the data to be preheated that the specified CDN network node needs to obtain is located.

[0043] The above data to be preheated usually includes the changed data in the source station, or may only include the data that only needs to be preheated among the changed data in the source station.

[0044] In the above first warm-up component, the correspondence between the CDN network node and the storage container is usually preset in advance, that is, the CDN network node that needs to perform data caching and the storage container where the changed data that the CDN network node needs to obtain is located. In actual implementation, the storage container where the data to be preheated is located in the source station can be obtained from the initial message, and the specified CDN network node can be determined according to the storage container. When the second warm-up component receives the warm-up message, it can send the warm-up message to the message queue in the specified CDN network node according to the specified CDN network node indicated by the warm-up message, so that the specified CDN network node can obtain the data to be preheated from the storage container according to the storage container where the changed data that the specified CDN network node needs to obtain is located as indicated by the warm-up message, and then cache the changed data into the specified CDN network node.

[0045] The present invention provides a method for preheating data in a CDN network. An initial message is obtained from a first message queue by a first preheating component; this message is pre-pushed to the first message queue by the CDN network source station; based on the initial message, a preheating message is generated; the preheating message is sent to a second preheating component; the preheating message is used to: instruct the second preheating component to notify a specified CDN network node to obtain data to be preheated from the source station. This method can quickly sense data changes in the source station through the first message queue and automatically trigger the preheating process; the initial preheating message is processed by the first preheating component, with stable performance and improved preheating efficiency. Moreover, the message queue and the preheating component have a flow-limiting effect on the preheating message, and the preheating process does not affect the normal operation of the CDN network, realizing smooth preheating of resources and ensuring the stability of the CDN network during the preheating process.

[0046] An embodiment of the present invention also provides another method for preheating data in a CDN network. This embodiment is implemented on the basis of the above embodiment. This embodiment focuses on describing the implementation process of the steps of generating a preheating message based on the initial message and sending the preheating message to the second preheating component (implemented through steps S304 - S306), as Figure 3 shown, and specifically includes the following steps:

[0047] Step S302, obtain an initial message from a first message queue by a first preheating component; wherein, the initial message is pre-pushed to the first message queue by the CDN network source station;

[0048] Step S304, screen out a legal initial preheating message from the initial message; wherein, the legal initial preheating message is used to: indicate that there is data to be preheated in the source station, and the data to be preheated is pre-set with a preheating function;

[0049] The above preheating function can be pre-set for the CDN network source station. The data that needs to be preheated is set with the preheating function, so that when the data in the source station changes, the initial message pushed by the CDN network source station to the first message queue includes a preheating identifier for preheating the changed data, that is, there is data to be preheated in the source station. For example, the first data and the third data in the source station need to be preheated. At this time, the first data and the third data can be pre-set with the preheating function. When the first data, the second data, and the third data all change, the first message queue will receive three initial messages. The first initial message includes a preheating identifier for the changed first data to be preheated; since the second data does not need to be preheated, the second initial message does not include a preheating identifier for the second data to be preheated; the third initial message includes a preheating identifier for the changed third data to be preheated. The preheating identifier may also include the storage container where the data to be preheated is located in the source station; or the storage container where the data to be preheated is located in the source station is directly included in the initial message.

[0050] In actual implementation, when the first preheating component obtains the initial message, it can screen and obtain a legal initial preheating message from the initial message according to the preheating identifier included in the initial message. Specifically, if the initial message includes the preheating identifier, the initial message can be determined as the initial preheating message. It can also screen and obtain a legal initial preheating message from the initial message according to the storage container where the data to be preheated in the source station is located and the preheating identifier included in the initial message. Specifically, if the storage container included in the initial message is the container that needs to be preheated and includes the preheating identifier, the initial message is determined as the initial preheating message.

[0051] Step S306: Generate a final preheating message based on the legal initial preheating message; send the final preheating message to the second preheating component; the final preheating message is used to: instruct the second preheating component to notify the specified CDN network node to obtain the data to be preheated from the source station.

[0052] Since the above legal initial preheating message indicates the data with the preheating function set among the data changed in the source station, the finally generated final preheating message is used to instruct the second preheating component to notify the specified CDN network node to obtain the data to be preheated from the source station, including only the data with the preheating function set in advance, and can preheat the data in the source station according to actual needs.

[0053] The present invention provides a data preheating method for a CDN network. The first preheating component obtains an initial message from the first message queue; the message is pre-pushed to the first message queue by the CDN network source station; a legal initial preheating message is screened from the initial message; a final preheating message is generated based on the legal initial preheating message; the final preheating message is sent to the second preheating component; the final preheating message is used to: instruct the second preheating component to notify the specified CDN network node to obtain the data to be preheated from the source station. This method can quickly sense the data changes in the source station through the first message queue and automatically trigger the preheating process; by screening and processing the initial preheating message through the first preheating component, the performance is stable, the preheating efficiency is improved, and the message queue and the preheating component have a flow-limiting effect on the preheating message. The preheating process does not affect the normal operation of the CDN network, realizing the smooth preheating of resources and ensuring the stability of the CDN network during the preheating process.

[0054] The embodiment of the present invention also provides another data preheating method for a CDN network. This embodiment is implemented on the basis of the above embodiment. This embodiment focuses on describing the specific implementation manner of the step of screening and obtaining a legal initial preheating message from the initial message (implemented through steps 021-022), and the specific implementation manner of the step of generating a final preheating message based on the legal initial preheating message (implemented through steps 03-04), and specifically includes the following steps:

[0055] Step 01, obtain the initial message from the first message queue through the first preheating component; wherein, the initial message is pre-pushed to the first message queue by the CDN network origin station;

[0056] Step 02, screen and obtain the legal initial preheating message from the initial message; wherein, the legal initial preheating message is used to: indicate that there is data to be preheated in the origin station, and the data to be preheated is pre-set with a preheating function;

[0057] The above initial message includes: the storage container where the relevant data of the initial message is located in the origin station, and the message attribute of the initial message; the relevant data therein can be the changed data, and the message attribute of the initial message is used to indicate that there is data to be preheated in the origin station. Specifically, the message attribute of the initial message can be determined by the identifier recorded on the message operation flag bit. If there is data to be preheated in the origin station, the identifier "update" is recorded on the message operation flag bit, indicating that there is data to be preheated in the origin station. If there is no identifier "update" recorded on the message operation flag bit of the initial message, it indicates that there is no data to be preheated in the origin station, that is, the changed data does not need to be preheated and cached.

[0058] A possible implementation:

[0059] Step 021, determine whether the storage container included in the initial message is a pre-specified legal container. If it is a pre-specified legal container, determine the initial message as a legal initial message; wherein, the data in the specified legal container is pre-set with a preheating function;

[0060] According to the actual needs of the user, it can be determined whether the containers under the user account need to be set with a preheating function. If the user sets a preheating function, all containers under the user account have the preheating function, and the containers under the user account can be understood as the above-specified legal containers. If the preheating function is a paid function, if the user has paid for the preheating function, that is, the containers under the user account can be understood as the above-specified legal containers.

[0061] The origin station first obtains whether the containers under a certain user account are set with a preheating function, and then notifies the first preheating component to modify the configuration in the first preheating component, so as to record in the first preheating component which containers are the specified legal containers.

[0062] In actual implementation, the first preheating component can obtain the storage container from the initial message. If the storage container is a pre-specified legal container, the initial message is determined as a legal initial message. If the storage container is not a pre-specified legal container, the initial message is directly discarded.

[0063] Step 022: Determine whether the message attribute of the legal initial message is the specified attribute. If so, determine the legal initial message as the legal initial preheating message. Herein, the specified attribute is used to indicate that there is data to be preheated in the source station.

[0064] Specifically, the first preheating component can obtain the identifier recorded on the message operation identification bit from the legal initial message. If the identifier is update, it indicates that there is data to be preheated in the source station, and the legal initial message can be determined as the legal initial preheating message. If the identifier is not update, the above initial message is other message and is not used to indicate whether there is data to be preheated in the source station, that is, the changed data does not need to be preheated and cached, and the legal initial message can be directly discarded.

[0065] Step 03: Obtain the preheating node corresponding to the data to be preheated that is preconfigured.

[0066] The above preheating node is the aforementioned CDN network node. Usually, each data to be preheated will have a corresponding cached CDN network node, that is, the above preheating node. Moreover, the corresponding relationship between the storage container and the preheating node is preconfigured in the first preheating component. When the first preheating component determines the legal preheating message, it can determine the corresponding preheating node according to the storage container where the data to be preheated is located included in the legal preheating message. In this way, the preheating node corresponding to the data to be preheated can be preconfigured. This flexible method of specifying the CDN network node for preheating speeds up the resource cache hit.

[0067] A possible implementation manner:

[0068] Step 031: Obtain the target storage container where the data to be preheated is located in the source station from the legal initial preheating message.

[0069] Usually, the initial message will include the storage container where the changed or updated data is located in the source station; similarly, the above legal initial preheating message will include the target storage container where the data to be preheated is located in the source station.

[0070] Step 032: Determine the target preheating node corresponding to the target storage container from the corresponding relationship between the storage container and the preheating node, and determine the target preheating node as the preheating node corresponding to the data to be preheated.

[0071] According to the corresponding relationship between the storage container and the preheating node provided by the program in the first preheating component, and according to the obtained target storage container, determine the target preheating node corresponding to the target storage container from the corresponding relationship between the storage container and the preheating node, that is, configure the corresponding preheating node for the target storage container in the legal initial preheating message, and then obtain the preheating node corresponding to the data to be preheated that is preconfigured.

[0072] Step 04: Generate a final preheating message based on the node identifier of the preheating node and a legal initial preheating message. The node identifier of the preheating node is used to instruct the second preheating component to notify the preheating node to obtain the data to be preheated from the source station.

[0073] The above node identifier can be the node information of the preheating node. For example, it can be the unique ID (Identity Document) of the preheating node, which is used to indicate the target CDN network node. In actual implementation, the node identifier of the preheating node can be added to the legal initial preheating message, and then the legal initial preheating message with the added node identifier is formatted so that the second preheating component can parse the node identifier therein, and then use the second preheating component to notify the preheating node to obtain the data to be preheated from the source station.

[0074] A possible implementation:

[0075] Step 041: Extract specified information from the legal initial preheating message. The specified information includes the resource location identifier and domain name information of the data to be preheated.

[0076] The above specified message is used to instruct the second preheating component to be able to obtain the data to be preheated in the target storage container according to the resource location identifier and domain name information. The resource location identifier therein can be a URL (Uniform Resource Locator), which is used to specify the location of the data to be preheated in the CDN network source station. The domain name information therein is also used to specify the location of the data to be preheated in the CDN network source station. In actual implementation, after the first preheating component obtains the preheating node corresponding to the preconfigured data to be preheated, in order to enable the preheating node to obtain the data to be preheated in the target storage container, the resource location identifier and domain name information of the data to be preheated can be extracted from the legal initial preheating message, so that the preheating node can obtain the data to be preheated from the source station through the resource location identifier and domain name information.

[0077] Step 042: Process the specified information and the node identifier of the preheating node according to the format corresponding to the second preheating component to obtain the final preheating message.

[0078] In order to enable the second preheating component to recognize the received final preheating message, the specified information and the node identifier of the preheating node can be formatted and processed in advance according to the format corresponding to the second preheating component to obtain the final preheating message. The final preheating message includes the specified information and the node identifier of the preheating node.

[0079] Step 05: Send the final preheating message to the second preheating component. The final preheating message is used to instruct the second preheating component to notify the specified CDN network node to obtain the data to be preheated from the source station.

[0080] It should be noted that the data to be preheated indicated by a legal initial preheating message may also include data to be preheated for which no corresponding preheating node is configured. Or, it can be understood that the target storage container included in the legal initial preheating message does not have a corresponding preheating node preconfigured. In this case, the node identifier of the preheating node will not be included in the final preheating message generated based on the node identifier of the preheating node and the legal initial preheating message.

[0081] In the above method, the CDN network origin can be set in multiple nodes and multiple operators, which is easy to expand, and has functions such as high availability, PB-level storage capacity, infinite expansion, and multi-region services. It can continuously and stably provide services externally, solve problems such as network fluctuations between CDN network nodes and the origin, and improve the success rate of data preheating. Secondly, the first preheating component can quickly detect data changes in the origin and automatically trigger resource preheating without manual operation; in this method, the preheating message is processed through the message queue and the preheating component, with stable performance and high preheating efficiency; at the same time, the message queue and the preheating component can limit the flow of the preheating message, and the preheating process does not affect the normal operation of the CDN network, realizing smooth preheating of resources and ensuring the stability of the CDN network during the preheating process.

[0082] An embodiment of the present invention provides another method for preheating data in a CDN network. This method is applied to a device running a second preheating component; the second preheating component is communicatively connected to the first preheating component; as Figure 4 shown, the method includes the following steps:

[0083] Step S402, receiving a preheating message through the second preheating component;

[0084] Step S404, pushing the preheating message into the second message queue corresponding to the specified CDN network node; the preheating message is used to: notify the specified CDN network node to obtain the data to be preheated from the CDN network origin.

[0085] If the above preheating message includes the node identifier of the preheating node, the preheating message can be pushed into the second message queue corresponding to the specified CDN network node according to the node identifier; if the above preheating message does not include the node identifier of the preheating node, the specified CDN network node can be determined according to the domain name information of the data to be preheated in the preheating node, where the specified CDN network node can be one or more; the function of the above second message queue is the same as that of the first message queue, and it can be RabbitMQ, or it can also be ActiveMQ, ZeroMQ, Kafka, RocketMQ, etc. Different CDN network nodes correspond to different second message queues.

[0086] The above preheating message is generated by the first preheating component in the following manner: obtaining an initial message from the first message queue; wherein, the initial message is pre-pushed to the first message queue by the CDN network origin server; generating a preheating message based on the initial message.

[0087] The present invention provides a method for preheating data in a CDN network. The second preheating component receives the preheating message; pushes the preheating message to the second message queue corresponding to the specified CDN network node; the preheating message is used to: notify the specified CDN network node to obtain the data to be preheated from the CDN network origin server; wherein, the preheating message is generated by the first preheating component in the following manner: obtaining an initial message from the first message queue; wherein, the initial message is pre-pushed to the first message queue by the CDN network origin server; generating a preheating message based on the initial message. This method can quickly sense data changes in the origin server through the first message queue and automatically trigger the preheating process; process the initial message through the first preheating component, and push the preheating message to the second message queue of the specified CDN network node through the second preheating component. Through the preheating component and the message queue, the performance of the preheating process is stable, the preheating efficiency is improved, and the preheating message has a current limiting effect. The preheating process does not affect the normal operation of the CDN network, realizes the smooth preheating of resources, and ensures the stability of the CDN network during the preheating process.

[0088] An embodiment of the present invention provides another method for preheating data in a CDN network. This embodiment is implemented on the basis of the above embodiment. This embodiment focuses on describing the specific implementation manner of the step of pushing the preheating message to the second message queue corresponding to the specified CDN network node, which specifically includes the following steps:

[0089] Step 401, receiving the preheating message through the second preheating component;

[0090] Step 402, pushing the preheating message to the second message queue corresponding to the specified CDN network node; the preheating message is used to: notify the specified CDN network node to obtain the data to be preheated from the CDN network origin server;

[0091] A possible implementation manner:

[0092] (1) If the node identifier of the preheating node is included in the preheating message, determine the node corresponding to the node identifier as the specified CDN network node;

[0093] (2) Push the preheating message to the second message queue corresponding to the specified CDN network node.

[0094] After receiving the preheating message, the second preheating component first caches it in the preheating queue and waits to be sent to the designated CDN network node. Usually, it first determines whether the preheating message includes the node identifier of the preheating node. If the preheating message includes the node identifier of the preheating node, the node corresponding to the node identifier is first determined as the designated CDN network node. Then the preheating message is pushed to the second message queue corresponding to the designated CDN network node. Finally, the preheating program in the designated CDN network node first pulls the preheating message in the order of the second message queue, and initiates a back-to-source request to the CDN network source station according to the resource location identifier of the data to be preheated in the preheating message. After receiving the back-to-source request, the CDN network source station caches the data to be preheated to the designated CDN network node.

[0095] Another possible implementation:

[0096] (1) If the preheating message does not include the node identifier of the preheating node, extract the domain name information of the data to be preheated from the preheating message;

[0097] (2) Obtain the regional scope involved in the domain name information, and determine the nodes within the regional scope as the designated CDN network nodes;

[0098] (3) Push the preheating message to the second message queue corresponding to the specified CDN network node.

[0099] After receiving the preheating message, the second preheating component first caches it in the preheating queue and waits to be sent to the designated CDN network node; usually, it first determines whether the preheating message includes the node identifier of the preheating node. Since some data to be preheated do not have a preconfigured corresponding preheating node, the preheating message may not include the node identifier of the preheating node. If the preheating message does not include the node identifier of the preheating node, the domain name information of the data to be preheated can be extracted from the preheating message. The domain name information can be a domain name topology, indicating the regional scope of the data to be preheated, and the nodes distributed within the regional scope are determined as designated CDN network nodes. For example, the regional scope involved in the acquired domain name information is Beijing and Tianjin, and the nodes distributed in Beijing and Tianjin can be determined as designated CDN network nodes. The designated CDN network node determined in this way is closest to the data to be preheated, which avoids network fluctuations caused by long-distance data caching, improves preheating stability, and ensures the success rate of preheating.

[0100] In the above method, the CDN network origin can be set up with multiple nodes and multiple operators, which is easy to expand and has functions such as high availability, PB-level storage capacity, unlimited expansion, and multi-region services. It can continuously and stably provide external services, solve problems such as network fluctuations between CDN network nodes and the origin, and improve the success rate of data preheating. In this method, the preheating messages are processed through a message queue and a preheating component, with stable performance and high preheating efficiency. At the same time, the message queue and the preheating component can limit the flow of preheating messages, and the preheating process does not affect the normal operation of the CDN network, realizing smooth preheating of resources and ensuring the stability of the CDN network during the preheating process.

[0101] See Figure 5 Referring to the specific process schematic diagram shown, this embodiment provides a specific method for preheating data in a CDN network. Multiple distributed KS3s (KS3 is a product that provides object storage services) in the figure correspond to the aforementioned CDN network origin, and can provide developers with an unlimited, multi-backup, distributed, and low-cost storage space solution; Kafka corresponds to the aforementioned first message queue; the automatic preheating client corresponds to the device running the first preheating component; the preheating client corresponds to the device running the second preheating component; RabbitMQ corresponds to the aforementioned second message queue; CDN corresponds to the aforementioned CDN network node. Using KS3 as the origin, the automatic preheating function of the origin is enabled. After the resources change, the changed messages (corresponding to the aforementioned initial messages) are pushed into the message queue Kafka. The content of the initial message includes the storage container bucket in the origin where the changed data is located, and the message operation identification bit in the initial message records update (corresponding to the aforementioned message attribute), indicating that there is data to be preheated in the origin.

[0102] Then, the automatic preheating client starts the consumption program. According to the storage container bucket included in the initial message, the expected initial messages (corresponding to the aforementioned legal initial preheating messages) are screened out. First, the pre-specified storage containers are screened out, and the unexpected initial messages are filtered. Then, the initial messages marked as update in the legal initial messages are determined as the expected initial messages, that is, the legal initial preheating messages. After obtaining the legal initial preheating messages, the legal initial preheating messages are reassembled and processed in the automatic preheating client to obtain the final preheating message. The process of reassembling and processing the legal initial preheating messages to obtain the final preheating message is the aforementioned process of generating the final preheating message based on the legal initial preheating messages. Finally, the final preheating message is sent to the preheating client (corresponding to the device running the second preheating component).

[0103] After receiving the final preheating message, the preheating client caches it into the preheating queue and waits to be sent down to CDNNodes (corresponding to the aforementioned specified CDN network nodes), where if the node identifier of the preheating node is included in the final preheating message, the final preheating message needs to be sent to the RabbitMQ message queue (corresponding to the aforementioned second message queue) of the specified node. Otherwise, it will be sent to the queue on the relevant nodes according to the domain name information of the data to be preheated. That is, the process of pushing the final preheating message to the second message queue corresponding to the specified CDN network node as described above. Finally, the preheating program in the specified CDN network node first pulls the final preheating message from the RabbitMQ message queue in sequence, and initiates a back-source request to the CDN network origin based on the resource location identifier of the data to be preheated in the final preheating message. After receiving the back-source request, the CDN network origin caches the data to be preheated to the specified CDN network node through the back-source response.
