Detailed Description
In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.
The traditional intelligent DNS user positioning scheduling all depends on an IP geographic library, the IP geographic library is divided based on an external network IP network segment, and the IP geographic library is essentially physically divided according to a physical network of a public network to be used as a logic configuration unit. And according to the mapping relation between the IP section and the geographic position in the library, the geographic position of the user is known, and a response result is made according to the geographic position. However, the operator does not maintain and provide the IP geographic library in a unified manner, and meanwhile, due to frequent network change of the operator, the CDN scheduling accuracy is low and the response speed of part of users for accessing the network content is slow because the CDN manufacturers obtain the IP through various channels with large errors. And the current method for bypassing the IP geographic bank depends on conversion of Local-DNS13, and Local-DNS13 is inconsistent and cannot be unified.
Under the condition of not influencing the original domain name service, the invention can divide the Virtual networks such as public networks, Private networks and even Virtual Private Clouds (VPCs) into finer granularity as a logic configuration unit without using an IP geographic library, configure the logical configuration unit in a one-stop way, perform high-precision edge scheduling, analyze the user request to the service node nearest to the user, enable the user to obtain the required content nearby, solve the congestion condition of the Internet network, improve the response speed and success rate of user access, and further improve the service use experience.
As shown in fig. 1, a domain name resolution scheduling system according to an embodiment of the present invention includes: client 10, Access-DNS11, GSLB-DNS12 and Local-DNS 13.
The client 10 is configured to send a domain name resolution request carrying a domain name to the Access-DNS11, and receive a resolution result returned by the Access-DNS 11.
The Access-DNS11 is used for receiving a domain name resolution request carrying a domain name sent by the client 10 and determining the domain name as an opened high-precision scheduling service domain name; sending the identity information ID and the domain name of the logical network node to a global load balancing domain name server GSLB-DNS12, and receiving a first resolution result obtained by resolving the domain name based on the ID of the logical network node by GSLB-DNS12, wherein the ID of the logical network node is sent by GSLB-DNS 12; the first parsing result is sent to the client 10.
The GSLB-DNS12 is configured to open a high-precision scheduling service domain name according to a request for opening a high-precision scheduling service domain name sent by the client 10; analyzing the domain name according to the ID and the domain name of the logic network node identity information sent by the Access domain name server Access-DNS11 to obtain a first analysis result; the first resolution result is sent to the Access-DNS11 so that the Access-DNS11 sends the first resolution result to the client 10.
And the Local-DNS13 is used for receiving the unopened high-precision scheduling service domain name resolution request sent by the Access-DNS11, resolving the domain name to obtain a second resolution result, and sending the second resolution result to the Access-DNS 11.
In the embodiment of the invention, an Access domain name server Access-DNS11 receives a domain name resolution request carrying a domain name sent by a client 10, and determines the domain name as an opened high-precision scheduling service domain name; the Access-DNS11 sends the identity information ID and the domain name of the logical network node to a global load balancing domain name server GSLB-DNS12, and receives a first resolution result obtained by resolving the domain name based on the logical network node ID by GSLB-DNS12, wherein the logical network node ID is sent by GSLB-DNS 12; the Access-DNS11 sends the first resolution result to the client 10. By adding the logic network nodes and the Access-DNS11, high-precision domain name resolution scheduling supporting fine-grained division is realized, so that a user can obtain required contents nearby, and the Access speed is improved.
In specific implementation, on the basis of a DNS technology, the invention realizes high-precision edge scheduling supporting fine-grained division by adding a logic network node concept and an Access-DNS11 device, and the main components of the system are shown in FIG. 2, wherein a plurality of clients 10 perform information interaction with Local-DNS13 or GSLB-DNS12 by taking an Access-DNS11 as a center.
It should be noted that the logical network node in the embodiment of the present invention is a virtual network concept, i.e. a combination of machines that can be grouped into one group.
The GSLB-DNS12 mainly supports the registration of logic network nodes, opens high-precision scheduling for domain names, and provides the capability of configuring and responding to analysis values in different logic network nodes according to domain names; Local-DNS13 provides existing Local DNS services; the Access-DNS11 serving as a central server in the embodiment of the invention can register a logical network node with GSLB-DNS12, synchronously open a high-precision scheduled domain name, and then serve as an Access point for domain name resolution of the logical network node to receive all DNS requests in the logical network; the client 10, which may be a server, a container, a home computer, etc., belongs to a certain logical network node, and all DNS resolutions of the client all point to Access-DNS11 of the logical network node.
As shown in fig. 3, the logic network node registration and high-precision scheduling service domain name opening process is as follows: 1) firstly, an Access-DNS11 is required to apply for registering a logic network node to a GSLB-DNS12 system; 2) GSLB-DNS12 returns a logic network node ID to Access-DNS11 according to the registration information; 3) the client 10 applies for opening a high-precision scheduling service domain name to the GSLB-DNS12 system; 4) and the Access-DNS11 and the GSLB-DNS12 system synchronously open the domain name information of high-precision scheduling.
The processing process of the request for the high-precision domain name in the embodiment of the invention is shown in fig. 4, and the specific flow is as follows: 1) the client 10 requests high-precision scheduling domain name resolution from the Access-DNS 11; 2) the Access-DNS11 judges that the domain name is the domain name with opened high-precision scheduling, injects the logic network node ID registered with GSLB-DNS12 before, and initiates request analysis to GSLB-DNS 12; 3) GSLB-DNS12 finds out the corresponding analysis configuration according to the domain name and the logic network node ID, and responds the first analysis result to the Access-DNS 11; 4) the Access-DNS11 responds to the first resolution result to the client 10.
For convenience of description, the internal modules of GSLB-DNS12 are described below, where GSLB-DNS12 may perform resolution according to the previously registered logical network node ID sent by Access-DNS11, that is, the logical network node ID and the first resolution result have a mapping relationship:
the GSLB-DNS12 includes a DNS request receiving module, a DNS request processing module, and a DNS request sending module, where the DNS request receiving module is configured to receive the request from the Access-DNS11 and then send the request to the DNS request processing module, and the DNS request sending module is configured to send the first resolution result processed by the DNS request processing module to the Access-DNS 11. For the DNS request processing module, a mapping relationship between the logical network node ID and the first resolution result is stored, as shown in the following table (table 1).
| Domain name | Logical network node ID | Analytic value |
| |
1 | 192.168.0.1 |
| aaa.bbb.ccc | 2 | 192.168.0.2 |
| xxx.yyy. |
1 | 192.168.0.3 |
TABLE 1
As can be seen from table 1, for each domain name, GSLB assigns a logical network node ID to each domain name, and for the same domain name, for example, aaa. bbb. ccc, there may be more than one logical network node ID, but for a group of domain names and logical network node IDs having a correspondence relationship, the resolution value is unique, for example, for the domain name aaa. bbb. ccc, if GSLB assigns a logical network node ID of 1, the first resolution result (i.e., resolution value) is 192.168.0.1, if GSLB assigns a logical network node ID of 2, the first resolution result (i.e., resolution value) is 192.168.0.2, and when the path blocking corresponding to the logical network node ID of 1 can automatically access the path corresponding to the logical network node ID of 2 for resolution. The embodiment of the invention introduces the logic network nodes, can configure in a one-stop way, has thinner granularity, can effectively solve the crowded condition of the Internet network and improve the response speed and the success rate of the user access.
The DNS request processing module is mainly used for domain name resolution, and finds the configuration of a resolution value mapped by the DNS request according to the domain name of the DNS request and the ID of the logic network node.
The processing process of the request for the non-high-precision domain name in the embodiment of the invention is shown in fig. 5, and the specific flow is as follows: 1) the client 10 requests the Access-DNS11 for domain name resolution without opening high-precision scheduling; 2) the Access-DNS11 judges that the domain name is not opened with high-precision scheduling, and directly returns to the Local-DNS13 for requesting resolution; 3) the Local-DNS13 responds to the second resolution result to the Access-DNS 11; 4) the Access-DNS11 responds to the second resolution result to the client 10.
The Access-DNS11 needs to determine a domain name in a domain name resolution request sent by the client 10, and if the request is a high-precision scheduling domain name resolution request, the domain name and a previously registered logical network node ID are sent to the GSLB-DNS12 for domain name resolution through a mapping relationship, and if the request is a non-high-precision scheduling domain name resolution request, the request is directly returned to the Local-DNS13 for resolution, and these two resolution modes improve the resolution efficiency, and in order to facilitate description of how to determine whether the domain name resolution request sent by the client 10 is the high-precision scheduling domain name resolution, the following describes internal modules of the Access-DNS 11:
the Access-DNS11 comprises a DNS request receiving module, a DNS request processing module and a DNS request sending module.
The DNS request receiving module is used to receive a domain name resolution request from the client 10, and then send the domain name resolution request to the DNS request processing module.
And a DNS request processing module, wherein a list of domain names with opened high-precision scheduling services is stored in the DNS request processing module, and the list is shown in the following table (table 2).
| Opened high-precision scheduling service domain name |
| aaa.bbb.ccc |
| xxx.yyy.zzz |
TABLE 2
The DNS request processing module may determine whether the domain name is in a list of domain names with high-precision scheduling services according to a domain name resolution request sent by the client 10, and if not, directly mark the domain name as Local and send the domain name to the DNS request sending module; and if so, injecting the logical network node ID into the NSID of the pseudo resource record OPT of the EDNS, marking the logical network node ID as gslb, and sending the logical network node ID to the DNS request sending module.
The DNS request sending module stores the address of Local-DNS 13: 192.168.0.1, if marked as Local, then sent to Local-DNS 13; if the flag is GSLB, it is sent to GSLB-DNS 12.
