Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, in particular to the field of cloud computing technology, and in particular to a resource processing method, device and equipment based on a hybrid CDN system. Background Art

[0002] Content Delivery Network (CDN) is a distributed network technology based on the Internet. CDN caches resource content on edge servers around the world, allowing users to obtain the required content faster, thereby increasing access speed and saving source site bandwidth pressure and costs.

[0003] CDN systems are generally multi-layered. The layer closest to the user terminal is called the edge layer, and the layer between the edge layer and the source station is called the parent layer. User requests will first hit the edge layer node, and the edge node consumes edge bandwidth for external services. If the edge layer node does not cache the corresponding resource, it needs to request the resource from the parent layer node, and this process will consume the external bandwidth of the parent layer node. The CDN bandwidth cost is mainly composed of the above-mentioned edge bandwidth cost and parent layer bandwidth cost. Summary of the invention

[0042] Figure 1a The present invention provides a flowchart of a resource processing method based on a hybrid CDN system according to an embodiment of the present invention. The method is applicable to the case where a portion of the parent layer bandwidth is transferred to a CDN hybrid node. The method can be executed by a resource processing device based on a hybrid CDN system, which can be implemented in software and / or hardware and can be integrated into an electronic device. Figure 1a As shown, the method is executed by a CDN edge node in a hybrid CDN system. The hybrid CDN system also includes a CDN parent node and a CDN hybrid node. The resource processing method based on the hybrid CDN system of this embodiment may include:

[0043] S101, in response to a user request, requesting resources from a CDN parent node, and the CDN parent node determining whether the user request satisfies a hybrid pull condition of a back-to-source CDN hybrid node;

[0044] S102: When the user request satisfies the hybrid pull condition, obtain the first resource to be accessed from the CDN hybrid node.

[0045] Figure 1b is a structural diagram of a hybrid CDN system provided according to an embodiment of the present disclosure, with reference to Figure 1bThe hybrid CDN system may include a CDN edge node 01, a CDN parent node 02, and a CDN hybrid node 03, wherein the CDN hybrid node 03 serves as a heterogeneous storage node for the CDN edge node 01. The CDN edge node 01 can not only obtain resource data by returning to the source through the CDN parent node 02, but also bidirectional data interaction can be performed between the CDN edge node 01 and the CDN hybrid node 03. The CDN edge node 01 can store resource data heterogeneously to the CDN hybrid node, so that other CDN edge nodes can download the resource data from the CDN hybrid node 03 without returning the resource data from the CDN parent node. Figure 1b and Figure 1c Compared with a CDN system that only includes CDN edge nodes and CDN parent layer nodes but does not include CDN hybrid nodes, by introducing CDN hybrid nodes, part of the parent layer bandwidth can be transferred to CDN hybrid nodes. It should be noted that the hybrid CDN system can be referred to as the XCDN system, and the CDN hybrid node can be referred to as the XCDN node.

[0046] In the embodiment of the present disclosure, the hybrid pull condition is used to characterize whether the user request satisfies the condition of obtaining resource data from the CDN hybrid node, that is, whether the user request satisfies the condition of returning to the source CDN hybrid node. Exemplarily, whether the user request satisfies the hybrid pull condition can be determined by whether the user request carries a CDN hybrid tag or whether there are resources to be accessed in the CDN hybrid node.

[0047] Specifically, the CDN edge node requests resources from the CDN parent node in response to the user request, and the CDN parent node determines whether the user request meets the hybrid pull conditions. If the user request meets the hybrid pull conditions, the first resource to be accessed is obtained from the CDN hybrid node; if the user request does not meet the hybrid pull conditions, the CDN parent node obtains the resource to be accessed from the source site and feeds it back to the CDN edge node.

[0048] The technical solution provided by the embodiment of the present disclosure obtains a hybrid CDN system by introducing a CDN hybrid node into the CDN system. When a user request meets the hybrid pull condition, the CDN edge node obtains the first resource to be accessed from the CDN hybrid node without obtaining it from the CDN parent node, thereby transferring part of the parent layer bandwidth to the CDN hybrid node, thereby improving the flexibility of resource processing.

[0049] In an optional implementation, the method further includes: when the user request satisfies the hybrid pull condition, also obtaining the metadata of the resource to be accessed fed back by the CDN parent node; after obtaining the first resource to be accessed from the CDN hybrid node, it also includes: using the metadata of the resource to be accessed to verify the first resource.

[0050] The meta information of the resource to be accessed may be the MD5 value of the resource to be accessed. When the user request meets the hybrid pull condition, the CDN parent node may also feed back the meta information of the resource to be accessed to the CDN edge node. After the CDN edge node obtains the first resource to be accessed from the CDN hybrid node, it may also use the meta information of the resource to be accessed to verify the first resource. Specifically, the MD5 value of the first resource may be calculated, and the MD5 value may be compared with the meta information obtained in advance from the CDN parent node. If the comparison is consistent, the first resource verification passes; if the comparison is inconsistent, the first resource verification fails and is unsafe.

[0051] It should also be noted that the CDN parent node can also determine whether the user request meets the hybrid pull condition in combination with the meta information of the resource to be accessed; if the CDN parent node does not have the meta information of the resource to be accessed, the user request does not meet the hybrid pull condition; otherwise, the user request meets the hybrid pull condition. By determining whether the user request meets the hybrid pull condition in combination with the meta information of the resource to be accessed, the efficiency of determining the hybrid pull condition can be improved, and by using the meta information of the resource to be accessed to verify the first resource obtained from the CDN hybrid node, the accuracy and integrity of the first resource can be improved.

[0052] In the present disclosure, CDN edge nodes and CDN parent layer nodes can form a CDN node cache system as an access layer, which is responsible for receiving and processing user requests and determining whether user requests meet the hybrid pull conditions, that is, controlling whether user requests return to the source CDN hybrid node, thereby improving service quality, data security, etc.

[0053] In an optional implementation, the unit bandwidth cost of the CDN parent node is higher than the unit bandwidth cost of the CDN hybrid node. By converting a portion of the parent layer bandwidth into the cheaper bandwidth of the CDN hybrid node, the bandwidth cost can be reduced, thereby achieving the effect of reducing the bandwidth cost.

[0054] Figure 2a 1 is a flowchart of another resource processing method based on a hybrid CDN system provided according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the method is executed by a CDN edge node in a hybrid CDN system, and the hybrid CDN system further includes a CDN parent node and a CDN hybrid node; the CDN hybrid node includes a CDN hybrid center and a CDN hybrid edge node. Figure 2a The resource processing method based on the hybrid CDN system of this embodiment may include:

[0055] S201, in response to a user request, requesting resources from a CDN parent node, and the CDN parent node determining whether the user request satisfies a hybrid pull condition of a back-to-source CDN hybrid node;

[0056] S202, when the user request meets the hybrid pull condition, request the CDN hybrid center for the resource to be accessed, and the CDN hybrid center determines the first CDN hybrid edge node where the resource to be accessed is located, and returns the address of the first CDN hybrid edge node;

[0057] S203: Acquire a first resource to be accessed from the first CDN hybrid edge node using the address of the first CDN hybrid edge node.

[0058] Among them, CDN hybrid nodes include CDN hybrid centers and CDN hybrid edge nodes (which can be called XCDN edge miners). CDN hybrid centers are used to process query requests and push requests of CDN hybrid edge nodes. Exemplarily, CDN hybrid centers can maintain the IP addresses and real-time status of CDN hybrid edge nodes, maintain hybrid resource indexes of resources cached by CDN hybrid nodes, facilitate querying the cache status and location of resources, and schedule CDN hybrid edge nodes.

[0059] Specifically, the CDN edge node requests resources from the CDN parent node in response to the user request, and the CDN parent node determines whether the user request meets the hybrid pull condition; if so, the CDN parent node can return the metadata of the resource to be accessed to the CDN edge node, and the CDN edge node requests the resource to be accessed from the CDN hybrid center, and the CDN hybrid center determines the CDN hybrid edge node where the resource to be accessed is located as the first CDN hybrid edge node, and returns the address of the first CDN hybrid edge node to the CDN edge node; the CDN edge node uses the address of the first CDN hybrid edge node to request resources from the first CDN hybrid edge node, and obtains the first resource fed back by the first CDN hybrid edge node. The CDN hybrid center can further improve the resource processing efficiency by uniformly scheduling the resources in each CDN hybrid edge node.

[0060] In an optional implementation, requesting the resource to be accessed from the CDN hybrid center, the CDN hybrid center determining the first CDN hybrid edge node where the resource to be accessed is located, and returning the address of the first CDN hybrid edge node, includes: requesting the resource to be accessed from the CDN hybrid center, the CDN hybrid center determining the first CDN hybrid edge node where the resource to be accessed is located based on a hybrid resource index, and returning the address of the first CDN hybrid edge node; wherein the hybrid resource index is generated based on the resources in each CDN hybrid edge node.

[0061] The CDN hybrid center has a hybrid resource index, which is generated based on the resources in each CDN hybrid edge node and may include a cache relationship between the CDN hybrid edge node and the resource. The CDN hybrid center can determine the resource to be accessed based on the hybrid resource index, select the first CDN hybrid edge node where the resource to be accessed is located from each CDN hybrid edge node, and obtain the address of the first CDN hybrid edge node. By maintaining the hybrid resource index, the CDN hybrid center can improve the efficiency of determining the first CDN hybrid edge node, thereby further improving the efficiency of resource processing.

[0062] The technical solution provided by the embodiment of the present disclosure can further improve resource processing efficiency by uniformly scheduling resources in each CDN hybrid edge node through a CDN hybrid center and maintaining a resource index of each CDN hybrid edge node in the CDN hybrid center.

[0063] In an optional implementation, the unit bandwidth cost of the CDN parent node is higher than the unit bandwidth cost of the CDN hybrid edge node.

[0064] Among them, the unit bandwidth cost of CDN hybrid edge nodes is even lower, and external services can be provided using X86 servers based on different network access types such as public network dedicated lines, public network aggregation, NAT1, NAT4, and edge resources embedded with dedicated SDKs. By converting part of the parent layer bandwidth into a cheaper CDN hybrid edge bandwidth, the bandwidth cost can be reduced. In addition, the present disclosure reduces the bandwidth cost by diverting the CDN parent layer bandwidth, so it is not limited by the bottleneck of the edge hit rate. Since user requests are served by CDN edge nodes, the cheap resources of CDN hybrid edge nodes only provide services as bypass caches of CDN edge nodes, and also avoids the stability problem of directly providing external services by cheap resources.

[0065] In an optional implementation, when the CDN hybrid center determines that there is no CDN hybrid edge node with the resource to be accessed, it re-requests the resource from the CDN parent node so that the CDN parent node feeds back the resource to be accessed.

[0066] In the embodiment of the present disclosure, if the CDN hybrid center determines that there is no resource to be accessed in the hybrid resource index, it can be determined that there is no CDN hybrid edge node with the resource to be accessed, and the CDN edge node can re-request the resource from the CDN parent node, so that the CDN parent node obtains the resource to be accessed from the source station and feeds back the resource to be accessed to the CDN edge node.

[0067] In an optional implementation, when the first CDN hybrid edge node does not return the resource to be accessed, the resource is requested again from the CDN parent node, so that the CDN parent node feeds back the resource to be accessed.

[0068] If the first CDN hybrid edge node does not return the resource to be accessed, the CDN edge node may request the resource from the CDN parent node again, so that the CDN parent node obtains the resource to be accessed from the source station and feeds back the resource to be accessed to the CDN edge node.

[0069] In the case that the CDN edge node cannot obtain the resource to be accessed through the CDN hybrid node, it can also re-access the CDN parent node to obtain the resource data. The above disaster recovery logic can further improve the success rate of resource processing and ensure the stability of user request processing.

[0070] It should also be noted that the circuit breaker logic can be added. When the number of failed requests for the same user reaches the threshold, the CDN hybrid center can be no longer requested; if multiple requests from different users fail to access the CDN center, the CDN hybrid center can be no longer requested for a period of time, and asynchronous detection and recovery logic can be added to control the latency of user requests.

[0071] Figure 2b is an interactive schematic diagram of a resource processing method based on a hybrid CDN system provided according to an embodiment of the present disclosure, with reference to Figure 2b , the CDN edge node determines whether it is necessary to enable the XCDN back to source according to the configuration. If necessary, the CDN edge node carries the XCDN back to source mark when it goes back to the upstream; the CDN parent node determines whether the resource to be accessed hits the resource metadata. If the resource to be accessed does not hit or the resource type cannot use XCDN back to source, it directly spits out the resource data of the resource to be accessed, otherwise it spits out the metadata of the resource to be accessed, that is, it meets the hybrid pull condition; when the hybrid pull condition is met, the CDN edge node requests the XCDN center to schedule the API interface, and the XCDN center determines whether there is an available XCDN edge node with the corresponding resource. If there is, it is selected as the first XCDN edge node, and the address of the first XCDN edge node is fed back to the CDN edge node; the CDN edge node requests the first resource from the first XCDN edge node through the HTTP GET interface; the first XCDN edge node determines whether the first resource exists, and if so, it is fed back to the CDN edge node. In addition, if the CDN edge node cannot obtain the first resource, it can re-access the CDN parent node to enable the CDN parent node to obtain resource data from the source station.

[0072] Figure 3 1 is a flowchart of another resource processing method based on a hybrid CDN system provided according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the method is executed by a CDN edge node in the hybrid CDN system, and the hybrid CDN system also includes a CDN parent node and a CDN hybrid node. Figure 3 The resource processing method based on the hybrid CDN system of this embodiment may include:

[0073] S301, in response to a user request, requesting resources from a CDN parent node, and the CDN parent node determining whether the user request satisfies a hybrid pull condition of a back-to-source CDN hybrid node;

[0074] If the user request meets the mixed pull condition, continue to execute S302; otherwise, jump to execute S303;

[0075] S302, obtaining a first resource to be accessed from a CDN hybrid node;

[0076] S303, obtaining a second resource to be accessed fed back by the CDN parent node;

[0077] S304: When the user request satisfies the hybrid push condition, the second resource is pushed to the CDN hybrid node for storage.

[0078] In the embodiment of the present disclosure, the hybrid pull condition is used to characterize whether the user request satisfies the condition of obtaining resource data from the CDN hybrid node; the hybrid push condition is used to characterize whether the user request satisfies the condition of pushing new resources obtained from the CDN parent node to the CDN hybrid node for caching, that is, it is used to characterize whether the user request satisfies the bypass caching condition.

[0079] In the embodiment of the present disclosure, the CDN edge node requests resources from the CDN parent node in response to the user request, and the CDN parent node determines whether the user request meets the hybrid pull condition. If the user request meets the hybrid pull condition, the first resource to be accessed is obtained from the CDN hybrid node.

[0080] If the user request does not meet the hybrid pull condition, the CDN parent node obtains the second resource to be accessed (i.e., the new resource) from the source station and feeds it back to the CDN edge node. The CDN edge node obtains the second resource from the CDN parent node and determines whether the second resource meets the hybrid push condition. Exemplarily, whether the user request meets the hybrid push condition can be determined by whether the user request carries the CDN hybrid mark. If the user request meets the hybrid push condition, the CDN edge node also pushes the second resource to the CDN hybrid node for storage, so that when other CDN edge nodes need to access the second resource, they can directly obtain it from the CDN hybrid node without having to obtain it from the CDN parent node.

[0081] The technical solution provided by the embodiment of the present disclosure obtains a hybrid CDN system by introducing a CDN hybrid node in the CDN system. When a user request meets the hybrid pull condition, the CDN edge node obtains the first resource to be accessed from the CDN hybrid node without obtaining it from the CDN parent node, thereby transferring a portion of the parent layer bandwidth to the CDN hybrid node. When a user request does not meet the hybrid pull condition, the CDN edge node obtains the second resource to be accessed from the CDN parent node, and determines whether the second resource meets the hybrid push condition. When the hybrid push condition is met, the second resource is also cached in the CDN hybrid node for subsequent access, thereby realizing the transfer of a portion of the parent layer bandwidth to the CDN hybrid node.

[0082] Figure 4a The flowchart of another resource processing method based on a hybrid CDN system is provided according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the method is executed by a CDN edge node in a hybrid CDN system, and the hybrid CDN system further includes a CDN parent node and a CDN hybrid node; the CDN hybrid node includes a CDN hybrid center and a CDN hybrid edge node. Figure 4a The resource processing method based on the hybrid CDN system of this embodiment may include:

[0083] S401, in response to a user request, requesting resources from a CDN parent node, and the CDN parent node determining whether the user request satisfies a hybrid pull condition of a back-to-source CDN hybrid node;

[0084] If the user request meets the mixed pull condition, continue to execute S402; otherwise, jump to execute S403;

[0085] S402, obtaining a first resource to be accessed from a CDN hybrid node;

[0086] S403, obtaining the second resource to be accessed fed back by the CDN parent node;

[0087] S404, when the user request satisfies the hybrid sub-condition, sending a push request to the CDN hybrid center, the CDN hybrid center determines whether the push request satisfies the push sub-condition, and when the push request satisfies the push sub-condition, allocates a second CDN hybrid edge node to the push request;

[0088] S405, push the second resource to the second CDN hybrid edge node, and synchronize the push status to the CDN hybrid center, so that the CDN hybrid center updates the hybrid resource index if the push is successful; the hybrid resource index is generated based on the resources in each CDN hybrid edge node.

[0089] Among them, the hybrid push condition may include a hybrid sub-condition and a push sub-condition. The hybrid sub-condition is used to characterize whether the user request needs to go back to the source CDN hybrid node, and the push sub-condition is used to characterize whether the user request satisfies the bypass cache situation. For example, it can be determined whether the user request hits the hybrid resource index, whether there is a second resource to be accessed in the second CDN hybrid node, etc. to determine whether the user request meets the push sub-condition.

[0090] Specifically, the CDN edge node requests resources from the CDN parent node in response to the user request, and the CDN parent node determines whether the user request meets the hybrid pull condition; if not, the CDN parent node obtains the second resource to be accessed (i.e., the new resource) from the source station, and feeds the second resource back to the CDN edge node. The CDN edge node also determines whether the user request meets the hybrid sub-condition. If the hybrid sub-condition is met, a push request is sent to the CDN hybrid center, and the CDN hybrid center determines whether the push request meets the push sub-condition. If the push sub-condition is met, a second CDN hybrid edge node is allocated, and the address of the second CDN hybrid edge node is fed back; the CDN edge node uses the address of the second CDN hybrid edge node to push the second resource to the cache in the second CDN hybrid edge node. It should be noted that if the user request does not meet the hybrid sub-condition or does not meet the push sub-condition, the operation is terminated, and there is no need to push the second resource to the bypass cache.

[0091] By judging whether the user request satisfies the hybrid sub-condition and the push sub-condition, if both are satisfied, it is determined that the user request satisfies the hybrid push condition, a second CDN hybrid edge node is allocated, and the address of the second CDN hybrid edge node is fed back to the CDN edge node, so that the CDN edge node caches the second resource in the second CDN hybrid edge node, which can improve the cache efficiency of the second resource, thereby further improving the resource processing efficiency. It should be noted that the CDN hybrid center also updates the hybrid resource index according to the cache status of the second resource.

[0092] In an optional implementation, when the user request carries a CDN hybrid tag, it is determined that the user request satisfies the hybrid sub-condition; and it is determined whether the push request satisfies the push sub-condition based on the bandwidth and / or storage space of the CDN hybrid edge node.

[0093] In the embodiment of the present disclosure, when a CDN hybrid node needs to be returned to the source, a CDN hybrid tag can be added to the user request. If the user request carries a CDN hybrid tag, the user request satisfies the hybrid sub-condition; otherwise, the hybrid sub-condition is not satisfied, and there is no need to cache the second resource in the bypass cache. In combination with the bandwidth and storage space of each CDN hybrid edge node, it is determined whether the second resource needs to be pushed to the CDN hybrid edge node. For example, a preset bandwidth threshold and storage space threshold can be used to determine whether there is a CDN hybrid edge node with an available bandwidth greater than the bandwidth threshold and an available storage space greater than the storage space threshold. If so, it can be determined that the push sub-condition is satisfied, and a CDN hybrid edge node with a larger available bandwidth and a larger available storage space can be selected as the second CDN hybrid edge node. By determining whether the hybrid sub-condition is satisfied and whether the push sub-condition is satisfied, the push efficiency of resources can be further improved, thereby further improving the resource processing efficiency.

[0094] In an optional implementation, the second resource fed back by the CDN parent node is obtained through the first thread, and the second resource is pushed to the CDN hybrid node for storage through the second thread; the first thread and the second thread are asynchronous.

[0095] The acquisition of the second resource and the cache push process of the second resource are performed asynchronously, so that the cache push does not affect the processing of the user request, thereby maintaining the stability of the user request.

[0096] The technical solution provided by the embodiment of the present disclosure obtains a hybrid CDN system by introducing a CDN hybrid node into the CDN system. When the user request does not meet the hybrid pull condition, the CDN edge node obtains the second resource to be accessed from the CDN parent node, and determines whether the user request meets the hybrid sub-condition. When the hybrid sub-condition is met, a push request is sent to the CDN hybrid center. The CDN hybrid center determines whether the push request meets the push sub-condition, and when the push sub-condition is met, a second CDN hybrid edge node is determined, so that the CDN edge node pushes the second resource to the second CDN hybrid edge node, thereby storing the second resource in the bypass cache for subsequent access, thereby realizing the transfer of a part of the parent layer bandwidth to the bypass cache.

[0097] Figure 4b is an interactive schematic diagram of a resource processing method based on a hybrid CDN system provided according to an embodiment of the present disclosure, with reference to Figure 4bIn the case where the user request does not meet the hybrid pull conditions, the CDN edge node can obtain the second resource from the CDN parent node. The CDN edge node determines whether it needs to be pushed to the XCDN according to the configuration. If necessary, it requests the push API interface of the XCDN center. The XCDN center determines whether it needs to be pushed to the XCDN edge node. If necessary, it selects the second XCDN edge node and feeds back the address of the second XCDN edge node. The CDN edge node pushes the second resource to the second XCDN edge node through the HTTP PUT interface. The second XCDN edge node processes the PUT request. After the second resource is transmitted, an index is established locally, and the deployment result is reported to the XCDN center. The XCDN center updates the hybrid resource index.

[0098] Figure 5a The present invention provides a flowchart of a resource processing method based on a hybrid CDN system according to an embodiment of the present invention. The method is applicable to the case where a portion of the parent layer bandwidth is transferred to a CDN hybrid node. The method can be executed by a resource processing device based on a hybrid CDN system, which can be implemented in software and / or hardware and can be integrated into an electronic device. The method is executed by a CDN hybrid node in a hybrid CDN system, and the hybrid CDN system also includes a CDN edge node and a CDN parent layer node. Figure 5a The resource processing method based on the hybrid CDN system of this embodiment may include:

[0099] S501, when the user request obtained by the CDN edge node meets the hybrid pull condition of the source CDN hybrid node, determine the first resource to be accessed;

[0100] S502: Feedback the first resource to be accessed to the CDN edge node.

[0101] Among them, the hybrid CDN system includes CDN edge nodes, CDN parent nodes and CDN hybrid nodes. The CDN edge node requests resources from the CDN parent node in response to user requests. The CDN parent node determines whether the user request meets the hybrid pull condition of the source CDN hybrid node. If the hybrid pull condition is met, the CDN edge node requests resources from the CDN hybrid node. The CDN hybrid node determines the first resource to be accessed and feeds back the first resource to the CDN edge node. If the hybrid pull condition is not met, the CDN parent node obtains the second resource to be accessed from the source station and feeds back the second resource to the CDN edge node. Through the CDN hybrid system including the CDN hybrid node, part of the parent layer bandwidth of the CDN edge node is transferred to the CDN hybrid node, so that the CDN edge node can obtain the second resource to be accessed from the CDN hybrid node.

[0102] In an optional implementation, the unit bandwidth cost of the CDN parent node is higher than the unit bandwidth cost of the CDN hybrid node.

[0103] Among them, the unit bandwidth cost of CDN hybrid edge nodes is lower. By converting part of the parent layer bandwidth into the cheaper CDN hybrid edge bandwidth, the bandwidth cost can be reduced. In addition, the present disclosure reduces the bandwidth cost by diverting the CDN parent layer bandwidth, so it is not limited by the bottleneck of the edge hit rate. Since user requests are served by CDN edge nodes, the cheap resources of CDN hybrid edge nodes only serve as bypass caches of CDN edge nodes, and also avoids the stability problem of directly serving external services with cheap resources.

[0104] The technical solution provided by the embodiment of the present disclosure obtains a hybrid CDN system by introducing a CDN hybrid node into the CDN system. When a user request meets the hybrid pull condition, the CDN hybrid node determines the first resource to be accessed and feeds back the first resource to the CDN edge node, thereby transferring a portion of the parent layer bandwidth to the CDN hybrid node, thereby improving the flexibility of resource processing and taking into account both bandwidth costs and the stability of external services.

[0105] In an optional implementation, the CDN hybrid node includes a CDN hybrid center and a CDN hybrid edge node; the method is performed by the CDN hybrid center; the determining the first resource to be accessed includes: determining the first CDN hybrid edge node where the resource to be accessed is located, and feeding back the address of the first CDN hybrid edge node, so that the CDN edge node uses the address of the first CDN hybrid edge node to obtain the first resource to be accessed from the first CDN hybrid edge node. Exemplarily, the unit bandwidth cost of the CDN parent node is higher than the unit bandwidth cost of the CDN hybrid edge node.

[0106] Among them, the CDN hybrid node includes a CDN hybrid center and a CDN hybrid edge node. Specifically, when the user request meets the hybrid pull condition, the CDN edge node requests the resource to be accessed from the CDN hybrid center, and the CDN hybrid center determines the CDN hybrid edge node where the resource to be accessed is located as the first CDN hybrid edge node, and returns the address of the first CDN hybrid edge node to the CDN edge node, and the CDN edge node uses the address of the first CDN hybrid edge node to request the resource from the first CDN hybrid edge node, and the first CDN hybrid edge node feeds back the first resource to the CDN edge node. The CDN hybrid center can further improve the resource processing efficiency by uniformly scheduling the resources in each CDN hybrid edge node.

[0107] In an optional implementation, determining the first CDN hybrid edge node where the resource to be accessed is located, and feeding back the address of the first CDN hybrid edge node, includes: determining the first CDN hybrid edge node where the resource to be accessed is located based on a hybrid resource index, and feeding back the address of the first CDN hybrid edge node; wherein the hybrid resource index is generated based on the resources in each CDN hybrid edge node.

[0108] In the embodiment of the present disclosure, the CDN hybrid center can determine the resource to be accessed based on the hybrid resource index, select the first CDN hybrid edge node where the resource to be accessed is located from each CDN hybrid edge node, and obtain the address of the first CDN hybrid edge node. The CDN hybrid center can improve the efficiency of determining the first CDN hybrid edge node by maintaining the hybrid resource index, thereby further improving the resource processing efficiency.

[0109] In an optional embodiment, the method further includes: when the user request does not meet the hybrid pull condition and the CDN edge node obtains the second resource to be accessed from the CDN parent node, determining whether the user request meets the hybrid push condition, and storing the second resource in the CDN hybrid node if the hybrid push condition is met.

[0110] Among them, the hybrid push condition is used to characterize whether the user request satisfies the situation of pushing the new resource obtained from the CDN parent node to the CDN hybrid node for caching. If the user request does not meet the hybrid pull condition, the CDN edge node obtains the second resource from the CDN parent node and determines whether the second resource meets the hybrid push condition; if the hybrid push condition is met, the CDN hybrid node also obtains the second resource pushed by the CDN edge node and stores the second resource, so that when other CDN edge nodes need to access the second resource, they can directly obtain it from the CDN hybrid node without obtaining it from the CDN parent node, thereby reducing the parent layer bandwidth.

[0111] In an optional implementation, the CDN hybrid node includes a CDN hybrid center and a CDN hybrid edge node, and the method is executed by the CDN hybrid center; determining whether the user request satisfies the hybrid push condition, and if the hybrid push condition is satisfied, storing the second resource in the CDN hybrid node, including: obtaining a push request sent by the CDN edge node if the user request satisfies the hybrid sub-condition; determining whether the push request satisfies the push sub-condition, and if the push sub-condition is satisfied, allocating a second CDN hybrid edge node to the push request, so that the CDN edge node pushes the second resource to the second CDN hybrid edge node, and synchronizes the push status with the CDN hybrid center, so that the CDN hybrid center updates the hybrid resource index if the push is successful; the hybrid resource index is generated based on the resources in each CDN hybrid edge node.

[0112] Among them, the hybrid push condition may include a hybrid sub-condition and a push sub-condition. The hybrid sub-condition is used to characterize whether the user request needs to return to the source CDN hybrid node, and the push sub-condition is used to characterize whether the user request satisfies the bypass cache situation.

[0113] Specifically, if the user request does not meet the hybrid pull condition, the CDN parent node determines the second resource to be accessed and feeds back the second resource to the CDN edge node. The CDN edge node also determines whether the user request meets the hybrid sub-condition. If the hybrid sub-condition is met, a push request is sent to the CDN hybrid center. The CDN hybrid center determines whether the push request meets the push sub-condition. If the push sub-condition is met, the CDN hybrid center allocates a second CDN hybrid edge node and feeds back the address of the second CDN hybrid edge node to the CDN edge node, so that the CDN edge node uses the address of the second CDN hybrid edge node to push the second resource to the second CDN hybrid edge node for cache. By judging whether the user request meets the hybrid sub-condition and the push sub-condition, if both are met, the CDN hybrid center allocates a second CDN hybrid edge node for the push request, and feeds back the address of the second CDN hybrid edge node to the CDN edge node, so that the CDN edge node caches the second resource in the second CDN hybrid edge node, which can improve the cache efficiency of the second resource, thereby further improving the resource processing efficiency.

[0114] In an optional implementation, when the user request carries a CDN hybrid tag, it is determined that the user request satisfies the hybrid sub-condition; and it is determined whether the push request satisfies the push sub-condition based on the bandwidth and / or storage space of the CDN hybrid edge node.

[0115] In the embodiment of the present disclosure, when there is a need to return to the source CDN hybrid node, a CDN hybrid tag can be added to the user request. If the user request carries the CDN hybrid tag, the user request satisfies the hybrid sub-condition; otherwise, the hybrid sub-condition is not satisfied. Combined with the bandwidth and storage space of each CDN hybrid edge node, it is determined whether the second resource needs to be pushed to the CDN hybrid edge node. By determining whether the hybrid sub-condition is satisfied and whether the push sub-condition is satisfied, the push efficiency of the resource can be further improved, thereby further improving the resource processing efficiency.

[0116] Figure 5b This is a service diagram of an XCDN center provided according to an embodiment of the present disclosure, with reference to Figure 5b, the XCDN center may include a state-aware service cluster, an index service cluster, and a scheduling service. When the user request meets the hybrid pull conditions, the CDN edge node requests resources from the scheduling service and carries the XCDN tag in the protocol; the scheduling service performs a consistent hash search through the index service cluster and returns a list of XCDN edge nodes that have the resources to be accessed; if the return is empty, it means that no XCDN edge node has the resource; the scheduling service can also query the status of each XCDN edge node that has the resources to be accessed through the state-aware service cluster, obtain the XCDN edge node that has the resources to be accessed and is active, select it as the first XCDN edge node, and feed back the address of the first XCDN edge node to the CDN edge node, so that the CDN edge node uses the address to request the first resource from the first XCDN edge node.

[0117] In the case where the user request does not meet the hybrid pull condition, the CDN edge node can obtain the second resource from the CDN parent node and send a push request for the second resource to the scheduling service. The scheduling service selects a suitable second XCDN edge node through the state-aware service cluster and feeds back the address of the second XCDN edge node to the CDN edge node, so that the CDN edge node uses the address to push the second resource to the second XCDN edge node cache. The scheduling service also obtains the cache status of the second resource, and in the case of the cache cost of the second resource, updates the hybrid resource index through the index service cluster.
