In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
The embodiment of the application can be applied to a fusion scene of a Content Delivery Network (CDN), and CDN fusion can be understood as mutually accessing CDN networks of different providers, communicating with each other, transmitting resources, expanding the resources and improving performance. As shown in fig. 1, the process of fusing content delivery networks in the embodiment of the present application may be applied to a server (or central server) of a first CDN network, where the first CDN network may perform probing on a second content delivery network, where the probing may be to obtain an analysis result of the second CDN in advance. Therefore, the domain name resolution result of the second CDN is stored and is directly used in subsequent access, and the processing efficiency is improved.
The embodiment of the present application provides a processing method based on a content delivery network CDN, which may detect a second IP address on a second content delivery network, and establish a correspondence between a first domain name and the second IP address, so as to access the second IP address more efficiently, and specifically, as shown in fig. 2, the method includes:
The embodiment of the application can record the corresponding relation among the target domain name, the first domain name and the second domain name of the same user, so that the target domain name can be mapped to the first domain name or the second domain name. The user is a user of the CDN service, and the user may use the service in the first CDN and the second CDN respectively, where in the first CDN, the user may access an IP address through the first domain name, and in the second CDN, the user may access an IP address (a second IP address) through the second domain name. The first CDN and the second CDN can be interconnected in the embodiment of the application, so that the first CDN and/or the second CDN are selected to provide services for the user when the user needs the first CDN and/or the second CDN. For example, when a second CDN is used to provide services to a user, a received access request may be scheduled to a node device of the second CDN by a server of the first CDN. The embodiment of the application may provide a management page, so that the network information of the second content distribution network and the domain name information of the target domain name are determined through the management page.
The second domain name in the second CDN may correspond to a plurality of second IP addresses, the plurality of second IP addresses correspond to different node devices in the second CDN, and the different node devices have different geographic attributes, that is, correspond to different home locations. Therefore, in order to more fully detect a second IP address corresponding to the second domain name in the second CDN, in the embodiment of the present application, a different first IP address may be added to the domain name resolution request, so as to detect a different second IP address. Specifically, as an optional embodiment, the method further includes: at least one first IP address is determined, wherein the attribute values of the geographical attributes of different first IP addresses differ. As an optional embodiment, the generating a domain name resolution request according to the second domain name includes: acquiring a first IP address, wherein the attribute value of the geographic attribute of the first IP address is a target value; and generating a domain name resolution request according to the second domain name, and adding the first IP address in the domain name resolution request to acquire the second IP address with the attribute value of the geographic attribute as a target value.
After the domain name resolution request is determined, the domain name resolution request may be sent to a second CDN, and the second CDN may resolve a second domain name in the domain name resolution request, determine at least one second IP address, and screen out a corresponding second IP address from the at least one second IP address according to an attribute of the first IP address, such as an IP address of a node device closest to a position corresponding to the first IP address, generate a corresponding domain name resolution result, and feed back the domain name resolution result to the server.
Step 208, establishing a corresponding relationship between the first domain name and the second IP address, so as to determine a second IP address corresponding to the second CDN when receiving an access request for the target domain name.
In this embodiment of the present application, the second IP address may be extracted from the domain name resolution result, and the corresponding first domain name is determined according to the corresponding relationship between the first domain name and the second domain name, so as to establish the corresponding relationship between the first domain name and the second IP address, and store the corresponding relationship between the first domain name and the second IP address, and specifically, as an optional embodiment, the method further includes: and adding the corresponding relation between the first domain name and the second IP address into a domain name resolution table. According to the embodiment of the application, the first domain name and the plurality of second IP addresses can be recorded in the domain name resolution table, and the attribute values of the geographic attributes corresponding to the second IP addresses can be recorded so as to process the access request. Specifically, as an optional embodiment, the method further includes: receiving an access request for a target domain name; determining a first domain name according to the target domain name; determining a corresponding second IP address according to the corresponding relation between the first domain name and the second IP address; sending the access request to the second IP address.
In an alternative embodiment, the server of the first CDN and the DNS server of the first CDN may be understood as a same device, so as to process the access request through the server. In another optional embodiment, the server of the first CDN and the DNS server of the first CDN may also be understood as two different devices, so that the server sends the domain name resolution table to the DNS server of the first CDN, and processes the access request through the DNS server of the first CDN. According to the method and the device, after the access request is received, the target domain name in the access request can be extracted, the corresponding first domain name is determined, the corresponding second IP address is determined according to the corresponding relation between the first domain name and the second IP address, and the access request is sent to the second IP address. Compared with a mode of fusing different content distribution networks by serially connecting a plurality of domain names (the domain names need to be analyzed, and the access efficiency is low), the method and the device for determining the second IP address can analyze the first domain name to determine the second IP address, and can improve the access efficiency.
The second IP address corresponding to the first domain name has a plurality of second IP addresses, and the second IP addresses correspond to different geographic attributes and/or different operation service attributes, so that the geographic attributes or operation service attributes of the device initiating the access may also be queried in the embodiment of the present application to determine the corresponding second IP address, specifically, as an optional embodiment, the determining the corresponding second IP address according to the correspondence between the first domain name and the second IP address includes: determining a third IP address corresponding to the access request; obtaining an attribute value of the geographic attribute of the third IP address; and inquiring a domain name resolution table according to the first domain name and the attribute value, and determining a corresponding second IP address. In the embodiment of the present application, a third IP address may be added in the access request, where the third IP address may be understood as an IP address of the device initiating the access, and the attribute of the third IP address includes: operational service attributes and geographic attributes. The embodiment of the application may determine an attribute value of the third IP address, and query the corresponding second IP address from the domain name resolution table according to the attribute value, so as to provide a service for the device initiating the access nearby through the second CDN.
In this embodiment of the application, a service user may use a service on the first CDN and the second CDN, a service IP address on the first CDN may be accessed through the first domain name, a service IP address on the second CDN may be accessed through the second domain name, and for convenience of user access, a target domain name may be further allocated to the first domain name and the second domain name, so that access is performed through the first domain name or the second domain name. The method and the device for analyzing the domain name of the service user can obtain a target domain name of the service user, determine a first domain name of the service user on the first CDN and a second domain name of the service user on the second CDN, then generate a domain name analysis request according to the second domain name, send the domain name analysis request to the second CDN, analyze the domain name analysis request by the second CDN, determine a corresponding second IP address, generate a domain name analysis result, and feed the domain name analysis result back to a service end of the first CDN, wherein the service end of the first CDN can extract the second IP address from the domain name analysis result and establish a corresponding relation between the first domain name and the second IP address, so that when an access request aiming at the target domain name is received, the second IP address corresponding to the second CDN is determined. Compared with a mode of fusing domain names of a plurality of different content distribution networks in series (the IP addresses are determined by multiple times of analysis), the method and the device for determining the content distribution network mapping the first domain name corresponding to the access request in the access stage to the second IP address can improve the access efficiency according to the corresponding relation between the first domain name and the second IP address.
In the embodiment of the present application, a plurality of independent CDN networks may be interconnected to improve performance, for example, a first content delivery network (or called first CDN) and a second content delivery network (or called second CDN) may be interconnected and merged. In the process of fusing a plurality of independent content distribution networks, the content distribution networks can be divided into two types, one type is a content distribution network needing to be fused into other content distribution networks and can be called as a fusion party; the other is a content distribution network that blends other content distribution networks into itself, which may be referred to as a blended-in party. The embodiment of the application can detect the IP address on the content delivery network of the merging party so as to store the analysis result of the CDN network of the merging party into the CDN network of the merged party in advance, thereby facilitating the subsequent processing by directly using the analysis result.
For convenience of description, in the embodiments of the present application, a description is given by taking a first content distribution network as a reference and a second content distribution network as an example of being merged into the first content distribution network. Specifically, as shown in fig. 1, the process of fusing the content delivery networks in the embodiment of the present application may be applied to a server (or called a central server) of a first CDN network, where the first CDN network may perform detection on a second content delivery network, where the detection may be understood as obtaining an analysis result of the second CDN in advance. Therefore, the domain name resolution result of the second CDN is stored and is directly used in subsequent access, and the processing efficiency is improved.
Therefore, a plurality of second IP addresses of the specified second domain name in the second CDN may be determined based on the resolution result, and the address attributes of the plurality of second IP addresses are different, that is, have different operator and home information. The address attribute may include an operation service attribute and a geographic attribute, where the geographic attribute may be understood as an attribute (or home location) of a geographic location, and the operation service attribute may be understood as operator information (e.g., information of an operator) providing an operation service.
In the embodiment of the present application, the second IP address of the second CDN may be detected through a Domain Name, where a mapping relationship exists between the Domain Name (Domain Name) and the IP address, and the mapping relationship is generally resolved through a Domain Name System (DNS).
The second IP address is an IP address for the second CDN to provide a service for a target user (service user), and the target user may use the service in the first CDN and the second CDN, respectively, so that the domain name of each user may correspond to the first domain name of the first CDN and the second domain name of the second CDN. Each domain name also corresponds to one or more IP addresses in each CDN. Therefore, in the server of the first CDN, the target domain name of the user, and the corresponding relationship between the corresponding first domain name and second domain name may be pre-stored. Where the user's target domain name may also be referred to as an alias, Canonical Name (CNAME), etc., CNAME allows multiple names to be mapped to the same computer, e.g., one domain name may be directed to an IP address and then the other domain names may be aliased to the domain name, and thus may be mapped to the IP address by an alias. Correspondingly, the corresponding relationship among the target domain name, the first domain name and the second domain name may be stored in the server of the first CDN.
According to the method and the device for the domain name resolution, the first domain name corresponding to the first CDN and the second domain name corresponding to the second CDN are determined according to the target domain name in the process that the first CDN and the second CDN are fused with each other and are mutually accessed, the first CDN can send a domain name resolution request to the second CDN, and the domain name resolution result is obtained and then can be stored. Wherein the domain name resolution request may be generated based on the second domain name. The second IP addresses may respectively correspond to different node devices in the second CDN, and therefore, the plurality of second IP addresses have different geographic attributes. In order to detect a second IP address with different geographic attributes, the embodiment of the present application may obtain at least one first IP address, where attribute values of geographic attributes of different first IP addresses are different. The first IP address may be understood as an IP address of an access terminal (or called a client terminal, a terminal device, etc.) initiating access, and the attribute of the first IP address may include an operation service attribute and a geographic attribute, so as to correspond to different operators and different attributions, respectively. The first IP address may be manually input, or may be obtained by analyzing the historical access request, and specifically, the embodiment of the present application may provide an interactive page, so that a worker sets a plurality of first IP addresses with different attributes in the interactive page. The embodiment of the application can also obtain a historical access request containing the first domain name, and perform screening analysis on the IP addresses in the historical access request, so as to screen out the IP addresses with attribute representatives as the first IP addresses.
After determining the first IP address and the second domain name, a domain name resolution request may be generated from the second domain name, and the first IP address may be added to the domain name resolution request, to send the domain name resolution request to the second CDN, which may resolve a second domain name in the domain name resolution request, determine at least one second IP address, and according to the attribute of the first IP address, screening out a corresponding second IP address (such as the IP address of the node device closest to the position corresponding to the first IP address) from at least one second IP address, generating a domain name resolution result, and feeds back the domain name resolution result to the server, the server can extract the second IP address from the domain name resolution result and establish the corresponding relation between the first domain name and the second IP address, to determine a second IP address corresponding to the second CDN when an access request for the target domain name is received. After determining the correspondence between the first domain name and the second IP address, the correspondence may be added to a domain name resolution table so as to process the access request according to the domain name resolution table.
After the domain name resolution table is determined, the access request in the access process may be processed according to the domain name resolution table, and in an optional embodiment, the detection process of the domain name resolution result and the access process after detection in this embodiment may be completed by the same device, or, of course, may be completed by different devices, respectively.
In the access process, an access request may be obtained in the embodiment of the present application, where the access request may include a target domain name and a third IP address, and the third IP address may be understood as an IP address of a device initiating access, where attributes of the third IP address include: operational service attributes and geographic attributes. After the DNS server obtains the access request, the DNS server may determine the corresponding first domain name according to the target domain name in the access request, thereby determining at least one second IP address according to the correspondence in the domain name resolution table, and based on the attribute value of the geographic attribute of the third IP address, screen the at least one second IP address to determine the second IP address corresponding to the access request, so as to send the access request to the second IP address. According to the embodiment of the application, in the fusion process of the first content distribution network and the second content distribution network, the IP address (the second IP address) on the second content distribution network can be detected, and the corresponding relation between the first domain name and the second IP address is established, so that the first domain name can be rapidly mapped to the second IP address through the corresponding relation, and the processing efficiency is improved.
The embodiment of the application can be applied to a CDN (content distribution network) fusion scene, the second IP address related to the second domain name can be obtained from the second CDN (content distribution network) in a mode of detecting the domain name resolution result in advance, and the corresponding relation between the first domain name and the second IP address is established according to the domain name corresponding relation between the second domain name and the first domain name, so that the access request can be resolved more efficiently, and the processing efficiency is improved.
