and the at least one cache server 130 is coupled to the task center server 110 and is adapted to receive the domain name information sent by the task center server 110 and resolve the domain name information to obtain the data resource from the source server, so as to provide the data resource to the outside.
The invention provides a system for realizing CDN access, which comprises a Web client, a task center server, a domain name resolution server and at least one cache server. In the system, a Web client receives domain name information of a source server to be accessed to a CDN, a task center server generates a configuration task for configuring the IP address of at least one cache server for the domain name information, and the configuration task is issued to a domain name resolution server; and sending the domain name information to at least one cache server. Therefore, the task center server can automatically generate the configuration task and automatically issue the configuration task, a CDN provider does not need to manually configure the task, and the efficiency of the configuration task is improved. And the domain name resolution server instantly receives the configuration task issued by the task center server and executes the configuration task to provide domain name resolution service, and the at least one cache server instantly receives the domain name information issued by the task center server and resolves the domain name information to acquire data resources from the source server, so as to externally provide the data resources, further improve the efficiency of the configuration task, embody instant effectiveness, do not need any waiting, and optimize the operation experience.
It should be noted that the Web (network or website) client provided by the present invention is an interface for inputting domain name information of an origin server to be accessed to the CDN, such as a browser.
Because a certain time is required in the configuration process of accessing the CDN, in the configuration process, for example, the task center server 110 issues a configuration task to the domain name resolution server 120 or issues domain name information to the at least one cache server 130, the domain name resolution server 120 executes the configuration task to provide a domain name resolution service, and the at least one cache server 130 resolves the domain name information to obtain a data resource from the origin server, so as to provide the data resource externally. Thus, when the visitor accesses the domain name resolution server or the cache server, the corresponding storage does not have domain name related information, which may cause the visitor to wait. In order to solve the problem, the invention provides corresponding solutions for a domain name resolution server and at least one cache server respectively.
The invention provides a preferred scheme for a domain name resolution server, wherein the domain name resolution server receives a domain name resolution request, the domain name resolution request carries domain name information to be resolved, and then whether the domain name information to be resolved is stored before the domain name resolution request is received (namely whether the IP address of at least one cache server is configured for the domain name information to be resolved before the domain name resolution server receives the domain name resolution request or not) is judged, if so, the domain name information to be resolved is directly resolved, and a resolution result is returned. Otherwise, executing the extensive analysis and returning the specified extensive analysis result. Therefore, the domain name resolution server provided by the invention can realize the real-time effect of configuration without waiting, and optimizes the operation experience.
Further, directly analyzing the domain name information to be analyzed, and returning an analysis result may be implemented by searching for an IP address of at least one cache server configured for the domain name information to be analyzed, and then selecting one of the IP addresses of the at least one cache server as the analysis result to be returned. For example, the domain name resolution server receives a domain name resolution request, where the domain name resolution request carries information of a domain name to be resolved as a domain name a, and the domain name resolution server receives an IP address of at least one cache server configured for the domain name a before the domain name resolution request as IP1, IP2, and IP3, and at this time, according to a preset selection policy (e.g., distance from the cache server to the user, response time, load of the cache server, and other comprehensive information), one IP address is selected from IP1, IP2, and IP3 and returned as a resolution result, so that data resources can be obtained from the cache server corresponding to the selected IP address.
In addition, if the domain name information to be resolved is not stored before receiving the domain name resolution request (that is, the domain name resolution server does not configure the IP address of at least one cache server for the domain name information to be resolved before receiving the domain name resolution request), performing the flooding resolution, and returning a specified flooding resolution result. Here, the present invention provides a preferable scheme, in which the domain name information to be resolved can be resolved to the IP address of the specified cache server, and the IP address of the specified cache server is returned as a global resolution result, so that the data resource can be acquired from the cache server corresponding to the specified IP address.
Secondly, aiming at least one cache server, in the preferred scheme provided by the invention, at least one cache server receives an access data request, the access data request carries an identifier of data to be accessed, and then whether the data to be accessed corresponding to the identifier of the data to be accessed is found is judged, if so (namely at least one cache server already receives domain name information issued by a task center server before receiving the access data request and analyzes the domain name information to obtain data resources from a source server), a search result is returned. Otherwise, a request for searching the domain name information is sent to the task center server, for example, an HTTP (Hypertext transfer protocol) request for searching the domain name information is sent to the task center server, where the domain name information is the domain name information of the source server corresponding to the identifier of the data to be accessed, and then, according to the domain name information returned by the task center server, the data resource is obtained from the source server corresponding to the domain name information, so as to provide the data resource to the outside. Therefore, the at least one cache server provided by the invention can realize the real-time effect of configuration without waiting, and the operation experience is optimized.
Various implementations of the various elements of the embodiment shown in fig. 1 are described above, and are described in detail below with reference to a specific embodiment. In this embodiment, an origin server P to be accessed to the CDN accesses the CDN by using the system for automatically accessing the CDN provided in fig. 1A to provide a data access service to the outside, and fig. 1B shows a schematic diagram of accessing the CDN by using the access system provided by the present invention to provide a data access service to the outside. The visitor inputs domain name information (e.g., domain name information of the source server P) at a browser client (which is different from the above-mentioned Web client and is a browser client on a terminal such as a mobile phone or a computer of the visitor) where the visitor is located, and the browser client sends a domain name resolution request (see a signal flow direction indicated by "1" in fig. 1B) to the domain name resolution server 120, where the domain name resolution request carries domain name information to be resolved. At this time, the domain name resolution server 120 determines whether the IP address of at least one cache server has been configured for the domain name information to be resolved before receiving the domain name resolution request, and if so, directly resolves the domain name information to be resolved, and returns a resolution result (a signal flow direction indicated by "2" in fig. 1B). Otherwise, the generic resolution is executed, and the specified generic resolution result is returned (the signal flow direction indicated by "2" in fig. 1B). Subsequently, the browser client where the visitor is located sends an access data request (a signal flow direction indicated by "3" in fig. 1B) to one cache server 130' of the at least one cache server 130 according to the resolved IP address of the cache server, where the access data request carries an identifier of data to be accessed. The cache server 130' receives the access data request, and further determines whether the data to be accessed corresponding to the identifier of the data to be accessed is found, and if so, returns the search result. Otherwise, a request for looking up domain name information is sent to the task center server 110 (the signal flow direction shown by "4" in fig. 1B), where the domain name information is the domain name information of the source server corresponding to the identifier of the data to be accessed. The task center server 110 returns the domain name information to the cache server 130' (the signal flow shown as "5" in FIG. 1B). Then, the cache server 130' obtains the data resource from the source server corresponding to the domain name information according to the domain name information returned by the task center server 110, and provides the data resource to the visitor (the signal flow direction shown by "6" in fig. 1B).
Based on the same inventive concept, an embodiment of the present invention further provides a method for implementing CDN access, and fig. 2 shows a flowchart of a method for implementing CDN access applied to a task center server according to an embodiment of the present invention. As shown in fig. 2, the method at least includes the following steps S202 to S204.

And step S304, executing a configuration task to provide domain name resolution service.
Since it takes a certain time for the task center server to issue the configuration task to the domain name resolution server and for the domain name resolution server to execute the configuration task to provide the domain name resolution service, when the visitor accesses the domain name resolution server, the corresponding storage does not have domain name related information, so that the visitor is in a waiting state. To solve this problem, the present invention provides a solution for a domain name resolution server.
In a preferred scheme provided by the present invention, the domain name resolution server receives a domain name resolution request, where the domain name resolution request carries domain name information to be resolved, and further determines whether the domain name information to be resolved is stored before receiving the domain name resolution request (i.e., whether the domain name resolution server configures an IP address of at least one cache server for the domain name information to be resolved before receiving the domain name resolution request), and if so, directly resolves the domain name information to be resolved, and returns a resolution result. Otherwise, executing the extensive analysis and returning the specified extensive analysis result. Therefore, the domain name resolution server provided by the invention can realize the real-time effect of configuration without waiting, and optimizes the operation experience.
Further, directly analyzing the domain name information to be analyzed, and returning an analysis result may be implemented by searching for an IP address of at least one cache server configured for the domain name information to be analyzed, and then selecting one of the IP addresses of the at least one cache server as the analysis result to be returned.
