Specifically, as shown in fig. 1, the CDN may include a plurality of edge scheduling systems, each edge scheduling system may be associated with a respective server cluster, and cache servers in the server clusters may store various network resources.
As shown in fig. 1, when a client needs to acquire a target resource, a resource acquisition request may be sent to a nearby edge scheduling system a, and then the edge scheduling system a may acquire the target resource from an associated server cluster. However, sometimes the edge scheduling system a may not be able to acquire the target resource from the associated server cluster, in this case, the edge scheduling system a may feed back a redirection link to the client, and through the redirection link, the client may initiate a resource acquisition request to the edge scheduling system B again, so as to attempt to acquire the target resource from the edge scheduling system B.
In the existing resource acquisition mode, when the edge scheduling system accessed by the client for the first time cannot provide the target resource, the client needs to initiate multiple resource acquisition requests to acquire the target resource, which undoubtedly increases the burden of the client and also affects the use experience of the user. In addition, when the client initiates a resource acquisition request to the edge scheduling system B for the second time, the client needs to perform communication negotiation with the edge scheduling system B. However, the credentials used in this communication negotiation process are typically not the client's own credentials, and thus the security of the established communication connection is not guaranteed. In view of this, a more convenient and safer resource acquisition method is needed.

Therefore, according to the technical scheme provided by the application, when the edge scheduling system which is accessed by the client nearby receives the resource acquisition request sent by the client, the corresponding target resource can be tried to be acquired from the associated server cluster. If the edge scheduling system cannot acquire the target resource, another target server cluster for storing the target resource may be queried, and a proxy scheduling request may be sent to the target edge scheduling system associated with the target server cluster, where the proxy scheduling request may be used to acquire the target resource from the target server cluster. Therefore, after receiving the proxy scheduling request, the target edge scheduling system can acquire the target resource from the target server cluster and feed the target resource back to the edge scheduling system accessed by the client.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The present application provides a resource acquisition method, which can be applied to the system shown in fig. 2. In the system, a client, an edge scheduling system which is accessed by the client nearby, a server cluster associated with the edge scheduling system, another target edge scheduling system, a target server cluster associated with the target edge scheduling system and a central scheduling system can be included. The client may be a terminal device used by a user, or may be software running in the terminal device. The client can access an edge scheduling system in the CDN system nearby and obtain the target resource from the edge scheduling system. The server cluster associated with the edge scheduling system may include a plurality of cache servers, each of which may be configured to store network resources, and the edge scheduling system may obtain target resources required by the client from one or more cache servers in the associated server cluster according to a preset scheduling policy. The other target edge scheduling system can communicate with the edge scheduling system which is accessed by the client nearby through a proxy mode (proxy). The target edge scheduling system may also have its own associated target server cluster, and one or more cache servers included in the target server cluster may also be used to store network resources. The central scheduling system may be configured to store resource scheduling information of each edge scheduling system, where the resource scheduling information may indicate which edge scheduling systems have the same resource pool. Each edge scheduling system can actively load the latest resource scheduling information from the central scheduling system, and meanwhile, the central scheduling system can also issue the latest resource scheduling information to each edge scheduling system according to a fixed period.
In the resource obtaining method provided in an embodiment of the present application, the execution main body may be an edge scheduling system to which the client accesses nearby. Referring to fig. 2 and 3, the method may include the following steps.
S1: and receiving a resource acquisition request which is sent by a client and points to a target resource, and attempting to acquire the target resource from the server cluster.
In this embodiment, the client and the nearby edge scheduling system may establish a TCP connection in advance through a three-way handshake principle, and subsequently, the client may send a resource acquisition request to the edge scheduling system through the TCP connection, and the edge scheduling system may also provide a corresponding target resource to the client through the TCP connection. In the process of establishing the TCP connection, the client and the edge scheduling system use an HTTP certificate, and the certificate is usually a certificate belonging to the client, so that the security of the established TCP connection can be guaranteed.
In this embodiment, after the TCP connection is established, the client may send a Resource obtaining request pointing to the target Resource to the edge scheduling system, where the Resource obtaining request may be a URL (Uniform Resource Locator). The resource obtaining request may carry a resource identifier of the target resource. For example, in one application example, the resource acquisition request may be https:// test.com.cn/xx.jpg, where xx.jpg may be the resource identification of the target resource in the form of the picture.
In this embodiment, after receiving the resource obtaining request, the edge scheduling system may schedule the resource obtaining request to a cache server in the associated server cluster for processing. Specifically, the edge scheduling system may schedule the resource acquisition request according to a pre-configured scheduling policy. For example, the edge scheduling system may calculate a hash value of the resource obtaining request through a consistent hash algorithm, and use the hash value in a corresponding cache server in the server cluster as the cache server to which the resource obtaining request is scheduled.
Of course, in practical applications, the edge scheduling system may also schedule the resource obtaining request according to other scheduling policies. For example, the edge scheduling system may detect the current load status of each cache server in the server cluster, and may schedule the resource acquisition request to the cache server with the lowest load.
In this embodiment, the edge scheduling system may attempt to acquire the corresponding target resource from the server cluster by scheduling the resource acquisition request to the cache server in the server cluster. Specifically, according to the scheduling manner of the consistent hash algorithm, after determining the cache server to which the resource acquisition request is mapped in the server cluster, the edge scheduling system may send the resource acquisition request to the cache server, so as to provide the target resource through the cache server. In addition, the edge scheduling system may also traverse each cache server in the server cluster, so as to attempt to acquire the target resource from each cache server in sequence, and after acquiring the target resource, the traversal process may be stopped. In this way, the edge scheduling system may attempt to provide the target resource through a single cache server, and may also attempt to acquire the target resource by traversing multiple cache servers.
S3: if the target resource cannot be acquired from the server cluster, another target server cluster for storing the target resource is inquired, and an agent scheduling request pointing to the target resource is sent to a target edge scheduling system associated with the target server cluster.
In this embodiment, if the cache server to which the resource obtaining request is mapped in the server cluster cannot provide the target resource, or each cache server in the server cluster cannot provide the target resource, it indicates that the edge scheduling system cannot obtain the target resource from the server cluster at present. The reason why the target resource cannot be acquired may be that the target resource does not exist in the cache server at present, but the resource information in the cache server is not updated in time, so that the client is mistakenly accessed to the edge scheduling system. At this time, in order to be able to correctly provide the target resource to the client, the edge scheduling system may query the CDN for another target server cluster for storing the target resource.
Specifically, each edge scheduling system in the CDN may report resource pool information of itself to the central scheduling system according to a specified time period, where the resource pool information may be a resource list of each resource currently stored in a server cluster associated with the edge scheduling system. Therefore, the central scheduling system can collect and analyze the resource scheduling information according to the resource pool information reported by each edge scheduling system, and the resource scheduling information can be used for representing the server cluster with the same resource pool. For example, for server clusters having the same resource pool, the central scheduling system may store the cluster identifiers of the server clusters and the system identifiers of the corresponding edge scheduling systems in the same scheduling set. In practical application, each edge scheduling system in the CDN may load the latest resource scheduling information from the central scheduling system according to a specified period, or each edge scheduling system may also receive the latest resource scheduling information that is actively issued by the central scheduling system, so that the current resource scheduling information in each edge scheduling system may be updated according to the latest resource scheduling information.
In this embodiment, if an edge scheduling system to which a client has access nearby cannot acquire a target resource from an associated server cluster, the edge scheduling system may read current resource scheduling information, and query, according to the current resource scheduling information, a target server cluster having the same resource pool as the server cluster associated with the edge scheduling system. Specifically, the edge scheduling system may use the cluster identifier of the server cluster associated with the edge scheduling system as an index condition, and query, in the resource scheduling information, other cluster identifiers that are in the same scheduling set as the cluster identifier, so as to determine a target server cluster corresponding to the other cluster identifiers.
In a practical application scenario, the resource scheduling information locally stored by the edge scheduling system may include an IP address library, and the IP address library may indicate IP addresses of server clusters having the same resource pool and IP addresses of edge scheduling systems associated with the server clusters. Thus, after the target service cluster is obtained through query, the edge scheduling system can send an agent scheduling request pointing to the target resource to the target edge scheduling system associated with the target server cluster in an agent mode.
In this embodiment, in order to let the target edge scheduling system know that the proxy scheduling request is sent in a proxy-based manner, the edge scheduling system to which the client has access may add a tag used for characterizing proxy scheduling in the resource obtaining request, and send the resource obtaining request carrying the tag to the target edge scheduling system as the proxy scheduling request. For example, the resource acquisition request sent by the client may be https:// test.com.cn/xx.jpg, and the tag characterizing the proxy scheduling may be wsiphost ═ proxy, so that after the tag is added to the resource acquisition request, a proxy scheduling request of https:// test.com.cn/xx.jpgwsiphost ═ proxy may be obtained. Therefore, data interaction can be carried out between the edge scheduling system and the target edge scheduling system in a proxy mode without carrying out an additional communication negotiation process, so that the insecurity of data transmission caused by insecurity of certificates in the communication negotiation process is avoided.
S5: and under the condition that the target edge scheduling system responds to the agent scheduling request and acquires the target resource from the target server cluster, receiving the target resource fed back by the target edge scheduling system and providing the target resource to the client.
In this embodiment, after receiving the proxy scheduling request, the target edge scheduling system may identify the resource identifier of the target resource from the proxy scheduling request, and may attempt to acquire the target resource from the associated target server cluster according to a similar scheduling manner in step S3. When the target edge scheduling system acquires the target resource, the target resource can be returned to the edge scheduling system. The edge scheduling system can provide the target resource to the client, thereby completing the resource acquisition process.
In one embodiment, if the target edge scheduling system still cannot acquire the target resource from the target server cluster, feedback information indicating that the resource cannot be acquired may be sent to the edge scheduling system. After receiving the feedback information indicating that the target resource cannot be obtained, which is sent by the target edge scheduling system, the edge scheduling system may query another server cluster, other than the target server cluster, for storing the target resource again according to the locally stored resource scheduling information, and send an agent scheduling request pointing to the target resource to an edge scheduling system associated with the another server cluster. Similarly, the server cluster associated with the edge scheduling system may also have the same resource pool as another server cluster obtained by querying.
The server clusters having the same resource pool are obtained by querying the current resource scheduling information. However, in practical applications, resources actually stored in some server clusters may not be consistent with the resource scheduling information, so that the target resources cannot be normally acquired, and thus, the target resources are tried to be acquired among different server clusters by using the technical solution provided by the above embodiment of the present application. Such a situation that the actually stored resource does not conform to the resource scheduling information may be corrected when the edge scheduling system reports the resource information, and a server cluster originally in the same scheduling set may be divided into different scheduling sets due to resource change. Therefore, the accuracy of the resource scheduling information can be ensured, and the success rate of resource acquisition can be improved.
Referring to fig. 4, the present application further provides an edge scheduling system, where the edge scheduling system is associated with a server cluster; the edge scheduling system includes:
the request processing unit is used for receiving a resource acquisition request which is sent by a client and points to a target resource, and attempting to acquire the target resource from the server cluster;

and the resource feedback unit is used for receiving the target resource fed back by the target edge scheduling system and providing the target resource to the client under the condition that the target edge scheduling system responds to the proxy scheduling request and acquires the target resource from the target server cluster.
In one embodiment, the proxy scheduling unit includes:
and the resource pool query module is used for reading the current resource scheduling information in the edge scheduling system and querying a target server cluster which has the same resource pool with the server cluster associated with the edge scheduling system according to the current resource scheduling information.

Therefore, after receiving the proxy scheduling request, the target edge scheduling system can acquire the target resource from the target server cluster and feed the target resource back to the edge scheduling system accessed by the client. Subsequently, the edge scheduling system may provide the target resource to the client, thereby completing the resource acquisition process.
