TECHNICAL FIELD

The present disclosure relates to the field of computer technologies and, in particular, to the field of cloud computing technology. Particularly, the present disclosure relates to a resource processing method and apparatus based on a hybrid content delivery network (CDN) system and a device.

BACKGROUND

CDN is an Internet-based distributed network technology. CDNs cache resource contents in edge servers all around the world so that users can acquire the required contents more quickly, thereby improving an access speed and reducing the bandwidth pressure and cost of an origin.

A CDN system is generally a multi-layer architecture. A layer closest to the users is called an edge layer, and a layer between the edge layer and the origin is called a parent layer. A user request is firstly sent to an edge node, and an external service of the edge node consumes an edge bandwidth. If the edge node has no corresponding resource cached, the edge node needs to request a resource from a parent node. This process consumes an external bandwidth of the parent node. The CDN bandwidth cost mainly consists of an edge bandwidth cost and a parent-layer bandwidth cost.

DETAILED DESCRIPTION

FIG. 1A is a flowchart of a resource processing method based on a hybrid CDN system according to an embodiment of the present disclosure. The method is applied to the case where part of a parent-layer bandwidth is transferred to a CDN hybrid node. The method can be executed by a resource processing apparatus based on the hybrid CDN system. The apparatus can be implemented by software and/or hardware and can be integrated into an electronic device. As shown in FIG. 1A, the method is performed by a CDN edge node in the hybrid CDN system, the hybrid CDN system further includes a CDN parent node and the CDN hybrid node, and the resource processing method based on the hybrid CDN system in this embodiment may include the following:

In S101, in response to a user request, a resource is requested from the CDN parent node, and the CDN parent node determines whether the user request satisfies a hybrid pull condition for pulling the resource from the CDN hybrid node.

In S102, when the user request satisfies the hybrid pull condition, a to-be-accessed first resource is acquired from the CDN hybrid node.

FIG. 1B is a structural diagram of a hybrid CDN system according to an embodiment of the present disclosure. Referring to FIG. 1B, the hybrid CDN system may include a CDN edge node 01, a CDN parent node 02, and a CDN hybrid node 03, where the CDN hybrid node 03 serves as a heterogeneous storage node for the CDN edge node 01. Not only can the CDN edge node 01 pull resource data from the CDN parent node 02, but also bidirectional data exchanges may be performed between the CDN edge node 01 and the CDN hybrid node 03. The CDN edge node 01 may heterogeneously store the resource data in the CDN hybrid node so that another CDN edge node can download the resource data from the CDN hybrid node 03 without pulling the resource data from the CDN parent node. In conjunction with FIGS. 1B and 1C, compared with a CDN system including only the CDN edge node and the CDN parent node and excluding the CDN hybrid node, the hybrid CDN system introduces the CDN hybrid node so that part of the parent-layer bandwidth can be transferred to the CDN hybrid node. It is to be noted that the hybrid CDN system may be simply referred to as an XCDN system and the CDN hybrid node may be simply referred to as an XCDN node.

In the embodiment of the present disclosure, the hybrid pull condition is used for representing whether the user request satisfies a condition for acquiring resource data from the CDN hybrid node, that is to say, whether the user request satisfies a condition for pulling the resource from the CDN hybrid node. For example, whether the user request satisfies the hybrid pull condition may be determined according to whether the user request carries a CDN hybrid flag or whether the CDN hybrid node has a to-be-accessed resource.

According to the technical solutions provided in the embodiment of the present disclosure, the CDN hybrid node is introduced into the CDN system so that the hybrid CDN system is obtained, and when the user request satisfies the hybrid pull condition, the CDN edge node acquires the to-be-accessed first resource from the CDN hybrid node without acquiring the resource from the CDN parent node so that part of the parent-layer bandwidth is transferred to the CDN hybrid node, thereby improving resource processing flexibility.

In an optional embodiment, the method further includes: when the user request satisfies the hybrid pull condition, acquiring meta information of the to-be-accessed resource fed back by the CDN parent node. After the to-be-accessed first resource is acquired from the CDN hybrid node, the method further includes checking the first resource by using the meta information of the to-be-accessed resource.

The meta information of the to-be-accessed resource may be a Message-Digest Algorithm 5 (MD5) value of the to-be-accessed resource. When the user request satisfies the hybrid pull condition, the CDN parent node may further feed back the meta information of the to-be-accessed resource to the CDN edge node. After acquiring the to-be-accessed first resource from the CDN hybrid node, the CDN edge node may further check the first resource by using the meta information of the to-be-accessed resource. Specifically, an MD5 value of the first resource may be calculated, and the MD5 value is compared with the meta information pre-acquired from the CDN parent node. If the MD5 value is consistent with the meta information, the first resource is checked successfully. If the MD5 value is inconsistent with the meta information, the first resource fails to be checked and is not secure.

In addition, it is to be noted that the CDN parent node may determine, in conjunction with the meta information of the to-be-accessed resource, whether the user request satisfies the hybrid pull condition. If the CDN parent node does not have the meta information of the to-be-accessed resource, the user request does not satisfy the hybrid pull condition. Otherwise, the user request satisfies the hybrid pull condition. Whether the user request satisfies the hybrid pull condition is determined in conjunction with the meta information of the to-be-accessed resource so that the determination efficiency of the hybrid pull condition can be improved, and the first resource acquired from the CDN hybrid node is checked by using the meta information of the to-be-accessed resource so that the accuracy and integrity of the first resource can be improved.

In the present disclosure, the CDN edge node and the CDN parent node may constitute a CDN node cache system serving as an access layer for receiving and processing the user request and determining whether the user request satisfies the hybrid pull condition, that is, controlling whether the user request pulls the resource from the CDN hybrid node, thereby improving the quality of service and data security.

In an optional embodiment, a unit bandwidth cost of the CDN parent node is higher than a unit bandwidth cost of the CDN hybrid node. Part of the parent-layer bandwidth is converted into the cheaper bandwidth of the CDN hybrid node so that a bandwidth cost can be reduced.

FIG. 2A is another flowchart of a resource processing method based on a hybrid CDN system according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the method is performed by a CDN edge node in the hybrid CDN system, the hybrid CDN system further includes a CDN parent node and a CDN hybrid node, and the CDN hybrid node includes a CDN hybrid center and a CDN hybrid edge node. Referring to FIG. 2A, the resource processing method based on the hybrid CDN system in this embodiment may include the following.

In S201, in response to a user request, a resource is requested from the CDN parent node, and the CDN parent node determines whether the user request satisfies a hybrid pull condition for pulling the resource from the CDN hybrid node.

In S202, when the user request satisfies the hybrid pull condition, a to-be-accessed resource is requested from the CDN hybrid center, and the CDN hybrid center determines a first CDN hybrid edge node where the to-be-accessed resource is located and returns an address of the first CDN hybrid edge node.

In S203, a to-be-accessed first resource is acquired from the first CDN hybrid edge node by using the address of the first CDN hybrid edge node.

The CDN hybrid node includes the CDN hybrid center and the CDN hybrid edge node (which may be referred to as an XCDN edge miner), and the CDN hybrid center is configured to process a query request and a push request from the CDN hybrid edge node. For example, the CDN hybrid center may maintain an IP address and a real-time status of the CDN hybrid edge node and maintain hybrid resource indexes of resources cached in the CDN hybrid node, facilitating a query of a caching status and a position of a resource and the scheduling of the CDN hybrid edge node.

Specifically, the CDN edge node requests the resource from the CDN parent node in response to the user request, and the CDN parent node determines whether the user request satisfies the hybrid pull condition. If the user request satisfies the hybrid pull condition, the CDN parent node may return meta information of the to-be-accessed resource to the CDN edge node, the CDN edge node requests the to-be-accessed resource from the CDN hybrid center, and the CDN hybrid center determines a CDN hybrid edge node where the to-be-accessed resource is located to be 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 requests the resource from the first CDN hybrid edge node by using the address of the first CDN hybrid edge node and acquires the first resource fed back by the first CDN hybrid edge node. The CDN hybrid center performs unified scheduling on resources in CDN hybrid edge nodes so that resource processing efficiency can be further improved.

In an optional embodiment, that the to-be-accessed resource is requested from the CDN hybrid center, and the CDN hybrid center determines the first CDN hybrid edge node where the to-be-accessed resource is located and returns the address of the first CDN hybrid edge node includes the following: the to-be-accessed resource is requested from the CDN hybrid center, and the CDN hybrid center determines, based on the hybrid resource indexes, the first CDN hybrid edge node where the to-be-accessed resource is located and returns the address of the first CDN hybrid edge node, where the hybrid resource indexes are generated based on the resources in the CDN hybrid edge nodes.

The CDN hybrid center has the hybrid resource indexes, and the hybrid resource indexes are generated based on the resources in the CDN hybrid edge nodes and may include a caching relationship between the CDN hybrid edge nodes and the resources. The CDN hybrid center may determine the to-be-accessed resource based on the hybrid resource indexes, select from the CDN hybrid edge nodes the first CDN hybrid edge node where the to-be-accessed resource is located, and acquire the address of the first CDN hybrid edge node. The CDN hybrid center maintains the hybrid resource indexes so that the determination efficiency of the first CDN hybrid edge node can be improved, further improving the resource processing efficiency.

According to the technical solutions provided in the embodiment of the present disclosure, the CDN hybrid center performs the unified scheduling on the resources in the CDN hybrid edge nodes and maintains the resource indexes of the CDN hybrid edge nodes so that the resource processing efficiency can be further improved.

In an optional embodiment, a unit bandwidth cost of the CDN parent node is higher than a unit bandwidth cost of the CDN hybrid edge node.

The CDN hybrid edge node has the cheaper unit bandwidth cost and may provide external services by using an x86 server based on different network access types such as public network private lines, public network aggregation, network address translation (NAT1), and NAT4 and edge resources embedded into a dedicated software development kit (SDK). Part of a parent-layer bandwidth is converted into a cheaper CDN hybrid edge bandwidth so that a bandwidth cost can be reduced. Moreover, in the present disclosure, a CDN parent-layer bandwidth is shunted so that the bandwidth cost is reduced without being limited by a bottleneck of an edge hit rate. In addition, the CDN edge node provides a service for the user request, and the cheap resource of the CDN hybrid edge node serves only as a bypass cache of the CDN edge node for providing the service, avoiding the problem of stability of an external service directly based on the cheap resource.

In an optional embodiment, when the CDN hybrid center determines that no CDN hybrid edge node has the to-be-accessed resource, the resource is re-requested from the CDN parent node so that the CDN parent node feeds back the to-be-accessed resource.

In the embodiment of the present disclosure, if the CDN hybrid center determines that the to-be-accessed resource does not exist in the hybrid resource indexes, the CDN hybrid center may determine that no CDN hybrid edge node has the to-be-accessed resource, and the CDN edge node may re-request the resource from the CDN parent node so that the CDN parent node acquires the to-be-accessed resource from an origin and feeds back the to-be-accessed resource to the CDN edge node.

In an optional embodiment, when the first CDN hybrid edge node does not return the to-be-accessed resource, the resource is re-requested from the CDN parent node so that the CDN parent node feeds back the to-be-accessed resource.

When the first CDN hybrid edge node does not return the to-be-accessed resource, the CDN edge node may re-request the resource from the CDN parent node so that the CDN parent node acquires the to-be-accessed resource from the origin and feeds back the to-be-accessed resource to the CDN edge node.

When the CDN edge node cannot acquire the to-be-accessed resource through the CDN hybrid node, the CDN edge node may re-access the CDN parent node to obtain resource data. Through the preceding disaster recovery logic, a success rate of resource processing can be further improved, and the stability with which the user request is processed can be ensured.

In addition, it is to be noted that a fuse logic may be further added. After the number of failures of the same user request reaches a threshold, the CDN hybrid center may no longer be requested. If multiple accesses of different user requests to the CDN hybrid center fail, the CDN hybrid center may no longer be requested within a period of time and an asynchronous probe recovery logic is added so that the delay of the user request is controlled.

FIG. 2B is a schematic diagram of interaction of a resource processing method based on a hybrid CDN system according to an embodiment of the present disclosure. Referring to FIG. 2B, the CDN edge node determines, according to a configuration, whether XCDN pulling needs to be enabled. If the XCDN pulling needs to be enabled, the CDN edge node carries an XCDN pulling flag when pulling the resource from an upstream. The CDN parent node determines whether the to-be-accessed resource hits meta information of a resource. If the to-be-accessed resource is missed or the XCDN pulling cannot be used for a resource type, resource data of the to-be-accessed resource is directly outputted. Otherwise, the meta information of the to-be-accessed resource is outputted, that is, the hybrid pull condition is satisfied. When the hybrid pull condition is satisfied, the CDN edge node requests an XCDN center to schedule an application programming interface (API). The XCDN center determines whether an available XCDN edge node has the corresponding resource. If so, the available XCDN edge node is selected as a first XCDN edge node, and an 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 an HTTP GET interface. The first XCDN edge node determines whether the first resource exists and feeds back the first resource to the CDN edge node if the first resource exists. In addition, if the CDN edge node cannot obtain the first resource, the CDN parent node may be re-accessed so that the CDN parent node acquires the resource data from the origin.

FIG. 3 is another flowchart of a resource processing method based on a hybrid CDN system according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the method is performed by a CDN edge node in the hybrid CDN system, and the hybrid CDN system further includes a CDN parent node and a CDN hybrid node. Referring to FIG. 3, the resource processing method based on the hybrid CDN system in this embodiment may include the following:

In S301, in response to a user request, a resource is requested from the CDN parent node, and the CDN parent node determines whether the user request satisfies a hybrid pull condition for pulling the resource from the CDN hybrid node.

When the user request satisfies the hybrid pull condition, S302 is performed. Otherwise, S303 is performed.

In S302, a to-be-accessed first resource is acquired from the CDN hybrid node.

In S303, a to-be-accessed second resource fed back by the CDN parent node is acquired.

In S304, when the user request satisfies a hybrid push condition, the second resource is pushed to the CDN hybrid node for storage.

In the embodiment of the present disclosure, the hybrid pull condition is used for representing whether the user request satisfies a condition for acquiring resource data from the CDN hybrid node, and the hybrid push condition is used for representing whether the user request satisfies the case where a new resource acquired from the CDN parent node is pushed to the CDN hybrid node for caching, that is, representing whether the user request satisfies the case of a bypass cache.

In the embodiment of the present disclosure, the CDN edge node requests the resource from the CDN parent node in response to the user request, the CDN parent node determines whether the user request satisfies the hybrid pull condition, and if the user request satisfies the hybrid pull condition, the to-be-accessed first resource is acquired from the CDN hybrid node.

If the user request does not satisfy the hybrid pull condition, the CDN parent node acquires the to-be-accessed second resource (that is, the new resource) from an origin and feeds back the to-be-accessed second resource to the CDN edge node. The CDN edge node acquires the second resource from the CDN parent node and determines whether the user request satisfies the hybrid push condition. For example, whether the user request satisfies the hybrid push condition may be determined according to whether the user request carries a CDN hybrid flag. If the user request satisfies the hybrid push condition, the CDN edge node pushes the second resource to the CDN hybrid node for storage so that when another CDN edge node needs to access the second resource, the second resource can be directly acquired from the CDN hybrid node without being acquired from the CDN parent node.

According to the technical solutions provided in the embodiment of the present disclosure, the CDN hybrid node is introduced into a CDN system so that the hybrid CDN system is obtained, and when the user request satisfies the hybrid pull condition, the CDN edge node acquires the to-be-accessed first resource from the CDN hybrid node without acquiring the resource from the CDN parent node so that part of a parent-layer bandwidth is transferred to the CDN hybrid node; when the user request does not satisfy the hybrid pull condition, the CDN edge node acquires the to-be-accessed second resource from the CDN parent node, determines whether the user request satisfies the hybrid push condition, and when the hybrid push condition is satisfied, caches the second resource in the CDN hybrid node for a subsequent access so that part of the parent-layer bandwidth is transferred to the CDN hybrid node.

FIG. 4A is another flowchart of a resource processing method based on a hybrid CDN system according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the method is performed by a CDN edge node in the hybrid CDN system, the hybrid CDN system further includes a CDN parent node and a CDN hybrid node, and the CDN hybrid node includes a CDN hybrid center and a CDN hybrid edge node. Referring to FIG. 4A, the resource processing method based on the hybrid CDN system in this embodiment may include the following.

In S401, in response to a user request, a resource is requested from the CDN parent node, and the CDN parent node determines whether the user request satisfies a hybrid pull condition for pulling the resource from the CDN hybrid node.

When the user request satisfies the hybrid pull condition, S402 is performed. Otherwise, S403 is performed.

In S402, a to-be-accessed first resource is acquired from the CDN hybrid node.

In S403, a to-be-accessed second resource fed back by the CDN parent node is acquired.

In S404, when the user request satisfies a hybrid sub-condition, a push request is sent to the CDN hybrid center, and the CDN hybrid center determines whether the push request satisfies a push sub-condition and, when the push request satisfies the push sub-condition, allocates a second CDN hybrid edge node to the push request.

In S405, the second resource is pushed to the second CDN hybrid edge node and a push status is synchronized to the CDN hybrid center so that the CDN hybrid center updates hybrid resource indexes in response to a push success, where the hybrid resource indexes are generated based on resources in CDN hybrid edge nodes.

A hybrid push condition may include the hybrid sub-condition and the push sub-condition. The hybrid sub-condition is used for representing whether the user request needs to pull the resource from the CDN hybrid node, and the push sub-condition is used for representing whether the user request satisfies the case of a bypass cache. For example, whether the user request hits a hybrid resource index or whether the to-be-accessed second resource exists in a second CDN hybrid edge node may be determined so that whether the push request satisfies the push sub-condition is determined.

Specifically, the CDN edge node requests the resource from the CDN parent node in response to the user request, the CDN parent node determines whether the user request satisfies the hybrid pull condition, and if the user request does not satisfy the hybrid pull condition, the CDN parent node acquires the to-be-accessed second resource (that is, a new resource) from an origin and feeds back the second resource to the CDN edge node. The CDN edge node further determines whether the user request satisfies the hybrid sub-condition and, when the hybrid sub-condition is satisfied, sends the 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 sub-condition is satisfied, allocates the second CDN hybrid edge node and feeds back an address of the second CDN hybrid edge node. The CDN edge node pushes the second resource to the second CDN hybrid edge node for caching by using the address of the second CDN hybrid edge node. It is to be noted that if the user request does not satisfy the hybrid sub-condition or the push sub-condition, the operation ends and the second resource does not need to be pushed to the bypass cache.

Whether the user request satisfies the hybrid sub-condition and the push sub-condition is determined, when both the hybrid sub-condition and the push sub-condition are satisfied, it is determined that the user request satisfies the hybrid push condition, the 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. Thus, the caching efficiency of the second resource can be improved, further improving resource processing efficiency. It is to be noted that the CDN hybrid center further updates the hybrid resource indexes according to a caching status of the second resource.

In an optional embodiment, when the user request carries a CDN hybrid flag, it is determined that the user request satisfies the hybrid sub-condition; and whether the push request satisfies the push sub-condition is determined according to a bandwidth of the CDN hybrid edge node and/or a storage space of the CDN hybrid edge node.

In the embodiment of the present disclosure, the CDN hybrid flag may be added to the user request if the resource needs to be pulled from the CDN hybrid node; if the user request carries the CDN hybrid flag, the user request satisfies the hybrid sub-condition; otherwise, the hybrid sub-condition is not satisfied, and the second resource does not need to be cached in the bypass cache. Whether the second resource needs to be pushed to the CDN hybrid edge node is determined in conjunction with the bandwidth and storage space of each CDN hybrid edge node. For example, a preset bandwidth threshold and storage space threshold may be used for determining whether a CDN hybrid edge node exists whose available bandwidth is greater than the bandwidth threshold or whose available storage space is greater than the storage space threshold. If so, it may be determined that the push sub-condition is satisfied, and a CDN hybrid edge node with a relatively large available bandwidth or a relatively large storage space may be selected as the second CDN hybrid edge node. Whether the hybrid sub-condition is satisfied and whether the push sub-condition is satisfied are determined so that resource pushing efficiency can be further improved, further improving the resource processing efficiency.

In an optional embodiment, the second resource fed back by the CDN parent node is acquired through a first thread, and the second resource is pushed to the CDN hybrid node for storage through a second thread, where the first thread is asynchronous with the second thread.

An acquisition process of the second resource and a pushing and caching process of the second resource are performed asynchronously so that the pushing and caching do not affect the processing of the user request, thereby maintaining the stability of the user request.

According to the technical solutions provided in the embodiment of the present disclosure, the CDN hybrid node is introduced into a CDN system so that the hybrid CDN system is obtained, when the user request does not satisfy the hybrid pull condition, the CDN edge node acquires the to-be-accessed second resource from the CDN parent node, determines whether the user request satisfies the hybrid sub-condition, and when the hybrid sub-condition is satisfied, sends the push request to the CDN hybrid center, and the CDN hybrid center determines whether the push request satisfies the push sub-condition and, when the push sub-condition is satisfied, determines the second CDN hybrid edge node so that the CDN edge node pushes the second resource to the second CDN hybrid edge node to cache the second resource in the bypass cache for a subsequent access so that part of a parent-layer bandwidth is transferred to the bypass cache.

FIG. 4B is a schematic diagram of interaction of a resource processing method based on a hybrid CDN system according to an embodiment of the present disclosure. Referring to FIG. 4B, when the user request does not satisfy the hybrid pull condition, the CDN edge node may acquire the second resource from the CDN parent node. The CDN edge node determines, according to a configuration, whether the second resource needs to be pushed to XCDN and if so, requests a push API of an XCDN center. The XCDN center determines whether the second resource needs to be pushed to an XCDN edge node and if so, selects a second XCDN edge node and feeds back an address of the second XCDN edge node. The CDN edge node pushes the second resource to the second XCDN edge node through an HTTP PUT interface. The second XCDN edge node processes a PUT request and after the second resource is transmitted, establishes an index locally and reports a deployment result to the XCDN center. The XCDN center updates the hybrid resource indexes.

FIG. 5A is a flowchart of a resource processing method based on a hybrid CDN system according to an embodiment of the present disclosure. The method is applied to the case where part of a parent-layer bandwidth is transferred to a CDN hybrid node. The method can be executed by a resource processing apparatus based on the hybrid CDN system. The apparatus can be implemented by software and/or hardware and can be integrated into an electronic device. The method is performed by the CDN hybrid node in the hybrid CDN system, and the hybrid CDN system further includes a CDN edge node and a CDN parent node. Referring to FIG. 5A, the resource processing method based on the hybrid CDN system in this embodiment may include the following:

In S501, when a user request acquired by the CDN edge node satisfies a hybrid pull condition for pulling a resource from the CDN hybrid node, a to-be-accessed first resource is determined.

In S502, the to-be-accessed first resource is fed back to the CDN edge node.

The hybrid CDN system includes the CDN edge node, the CDN parent node, and the CDN hybrid node. The CDN edge node requests the resource from the CDN parent node in response to the user request, and the CDN parent node determines whether the user request satisfies the hybrid pull condition for pulling the resource from the CDN hybrid node. When the hybrid pull condition is satisfied, the CDN edge node requests the resource from the CDN hybrid node. The CDN hybrid node determines the to-be-accessed first resource and feeds back the first resource to the CDN edge node. When the hybrid pull condition is not satisfied, the CDN parent node acquires a to-be-accessed second resource from an origin and feeds back the second resource to the CDN edge node. The hybrid CDN system including the CDN hybrid node transfers part of the parent-layer bandwidth of the CDN edge node to the CDN hybrid node so that the CDN edge node can acquire the to-be-accessed first resource from the CDN hybrid node.

In an optional embodiment, a unit bandwidth cost of the CDN parent node is higher than a unit bandwidth cost of the CDN hybrid node.

A CDN hybrid node has the cheaper unit bandwidth cost. Part of the parent-layer bandwidth is converted into a cheaper CDN hybrid edge bandwidth so that a bandwidth cost can be reduced. Moreover, in the present disclosure, a CDN parent-layer bandwidth is shunted so that the bandwidth cost is reduced without being limited by a bottleneck of an edge hit rate. In addition, the CDN edge node provides a service for the user request, and the cheap resource of the CDN hybrid edge node serves only as a bypass cache of the CDN edge node for providing the service, avoiding the problem of stability of an external service directly based on the cheap resource.

In an optional embodiment, the CDN hybrid node includes a CDN hybrid center and the CDN hybrid edge node, and the method is performed by the CDN hybrid center. The operation of determining the to-be-accessed first resource includes: determining a first CDN hybrid edge node where a to-be-accessed resource is located and feeding back an address of the first CDN hybrid edge node so that the CDN edge node acquires the to-be-accessed first resource from the first CDN hybrid edge node by using the address of the first CDN hybrid edge node. For example, the unit bandwidth cost of the CDN parent node is higher than a unit bandwidth cost of the CDN hybrid edge node.

The CDN hybrid node includes the CDN hybrid center and the CDN hybrid edge node. Specifically, when the user request satisfies the hybrid pull condition, the CDN edge node requests the to-be-accessed resource from the CDN hybrid center. The CDN hybrid center determines a CDN hybrid edge node where the to-be-accessed resource is located to be 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 requests the resource from the first CDN hybrid edge node by using the address of the first CDN hybrid edge node. The first CDN hybrid edge node feeds back the first resource to the CDN edge node. The CDN hybrid center performs unified scheduling on resources in CDN hybrid edge nodes so that resource processing efficiency can be further improved.

In an optional embodiment, determining the first CDN hybrid edge node where the to-be-accessed resource is located and feeding back the address of the first CDN hybrid edge node includes determining, based on hybrid resource indexes, the first CDN hybrid edge node where the to-be-accessed resource is located and feeding back the address of the first CDN hybrid edge node, where the hybrid resource indexes are generated based on the resources in the CDN hybrid edge nodes.

In the embodiment of the present disclosure, the CDN hybrid center may determine the to-be-accessed resource based on the hybrid resource indexes, select from the CDN hybrid edge nodes the first CDN hybrid edge node where the to-be-accessed resource is located, and acquire the address of the first CDN hybrid edge node. The CDN hybrid center maintains the hybrid resource indexes so that the determination efficiency of the first CDN hybrid edge node can be improved, further improving the resource processing efficiency.

In an optional embodiment, the method further includes: when the user request does not satisfy the hybrid pull condition and the CDN edge node acquires the to-be-accessed second resource from the CDN parent node, determining whether the user request satisfies a hybrid push condition and, when the user request satisfies the hybrid push condition, storing the second resource in the CDN hybrid node.

The hybrid push condition is used for representing whether the user request satisfies the case where a new resource acquired from the CDN parent node is pushed to the CDN hybrid node for caching. If the user request does not satisfy the hybrid pull condition, the CDN edge node acquires the second resource from the CDN parent node and determines whether the user request satisfies the hybrid push condition. If the hybrid push condition is satisfied, the CDN hybrid node acquires the second resource pushed by the CDN edge node and stores the second resource so that when another CDN edge node needs to access the second resource, the second resource can be directly acquired from the CDN hybrid node without being acquired from the CDN parent node, thereby reducing the parent-layer bandwidth.

In an optional embodiment, the CDN hybrid node includes the CDN hybrid center and the CDN hybrid edge node, and the method is performed by the CDN hybrid center. The operation of determining whether the user request satisfies the hybrid push condition and, when the user request satisfies the hybrid push condition, storing the second resource in the CDN hybrid node include the following: when the user request satisfies a hybrid sub-condition, a push request sent by the CDN edge node is acquired; whether the push request satisfies a push sub-condition is determined, when the push request satisfies the push sub-condition, a second CDN hybrid edge node is allocated to the push request so that the CDN edge node pushes the second resource to the second CDN hybrid edge node and synchronizes a push status to the CDN hybrid center, and the CDN hybrid center updates the hybrid resource indexes in response to a push success, where the hybrid resource indexes are generated based on the resources in the CDN hybrid edge nodes.

The hybrid push condition may include the hybrid sub-condition and the push sub-condition. The hybrid sub-condition is used for representing whether the user request needs to pull the resource from the CDN hybrid node, and the push sub-condition is used for representing whether the user request satisfies the case of the bypass cache.

Specifically, if the user request does not satisfy the hybrid pull condition, the CDN parent node determines the to-be-accessed second resource and feeds back the second resource to the CDN edge node. The CDN edge node determines whether the user request satisfies the hybrid sub-condition and, when the hybrid sub-condition is satisfied, sends the push request to the CDN hybrid center. The CDN hybrid center determines whether the push request satisfies the push sub-condition. When the push sub-condition is satisfied, the CDN hybrid center allocates the second CDN hybrid edge node and feeds back an address of the second CDN hybrid edge node to the CDN edge node so that the CDN edge node pushes the second resource to the second CDN hybrid edge node for caching by using the address of the second CDN hybrid edge node. Whether the user request satisfies the hybrid sub-condition and the push sub-condition is determined, and when both the hybrid sub-condition and the push sub-condition are satisfied, the CDN hybrid center allocates the second CDN hybrid edge node to 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. Thus, the caching efficiency of the second resource can be improved, further improving the resource processing efficiency.

FIG. 5B is a schematic diagram of services of an XCDN center according to an embodiment of the present disclosure. Referring to FIG. 5B, the XCDN center may include a status awareness service cluster, an index service cluster, and a scheduling service. When the user request satisfies the hybrid pull condition, the CDN edge node requests the resource from the scheduling service and carries an XCDN flag in a protocol. The scheduling service searches for consistent hashing through the index service cluster and returns a list of XCDN edge nodes with the to-be-accessed resource. If a null list is returned, it indicates that no XCDN edge node has the resource. The scheduling service may further query, through the status awareness service cluster, a status of each XCDN edge node with the to-be-accessed resource, select an active XCDN edge node with the to-be-accessed resource as a first XCDN edge node, and feed back an address of the first XCDN edge node to the CDN edge node so that the CDN edge node requests the first resource from the first XCDN edge node by using the address.

When the user request does not satisfy the hybrid pull condition, the CDN edge node may acquire the second resource from the CDN parent node and send the push request for the second resource to the scheduling service. The scheduling service selects a proper second XCDN edge node through the status awareness service cluster and feeds back an address of the second XCDN edge node to the CDN edge node so that the CDN edge node pushes the second resource to the second XCDN edge node for caching by using the address. The scheduling service further acquires a caching status of the second resource and when the second resource is cached successfully, updates the hybrid resource indexes through the index service cluster.

According to the technical solutions in the embodiment of the present disclosure, a conventional CDN resource pulling architecture is adjusted so that part of the parent-layer bandwidth of the CDN edge node for pulling the resource from an upstream node is transferred to the cheaper XCDN, effectively reducing a CDN parent-layer bandwidth cost. Based on the processing capability of the CDN edge node, the corresponding data check and disaster recovery logic are designed to ensure the stability of processing client requests and avoid a quality damage caused by the use of a cheap resource for providing an external service. The massive resource index establishment, resource deployment, and status awareness capabilities of an XCDN center and an XCDN edge node provide a cheap bypass cache for a cache system of the CDN edge node, thereby implementing the processes of pushing new resources and pulling old resources.
