All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
Traditional intelligent DNS user positioning scheduling relies on an IP geographic library which is divided based on an external network IP network segment, and is essentially divided physically according to a physical network of a public network as a logic configuration unit. And according to the mapping relation between the IP section in the library and the geographic position, the geographic position of the user is known, and a response result is made according to the geographic position. However, the operators do not uniformly maintain and provide the IP geographic library, and meanwhile, as the network of the operators is frequently changed, the CDN manufacturer has larger errors in the IP obtained through various channels, so that the CDN scheduling accuracy is lower, and the response speed of partial users for accessing network contents is slower. Moreover, the current method for bypassing the IP geographic library relies on Local-DNS13 conversion, and Local-DNS13 is inconsistent and cannot be unified.
The invention can divide the public network, private network and virtual private cloud (Virtual Private Cloud, VPC) as a logic configuration unit in finer granularity without affecting the original domain name service, can perform one-stop configuration, performs high-precision edge scheduling, analyzes the user request to the service node nearest to the user, enables the user to obtain the required content nearby, solves the congestion condition of the Internet network, and improves the response speed and success rate of the user access, thereby improving the service 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-DNS13.
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-DNS11.
The Access-DNS11 is configured to receive a domain name resolution request carrying a domain name sent by the client 10, and determine that the domain name is an opened high-precision dispatch service domain name; transmitting the logic network node identity information ID and the domain name to a global load balancing domain name server GSLB-DNS12, and receiving a first analysis result obtained by analyzing the domain name by the GSLB-DNS12 based on the logic network node ID, wherein the logic network node ID is transmitted by the GSLB-DNS12; the first parsing result is transmitted to the client 10.
GSLB-DNS12, which is used to open the high-precision dispatch service domain name according to the request sent by the client 10; resolving the domain name according to the logic network node identity information ID and the domain name sent by the Access domain name server Access-DNS11 to obtain a first resolving 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.
The Local-DNS13 is configured to receive an unopened domain name resolution request of the high-precision scheduling service sent by the Access-DNS11, resolve the domain name to obtain a second resolution result, and send the second resolution result to the Access-DNS11.
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 that the domain name is an opened high-precision dispatch service domain name; the Access-DNS11 sends the logic network node identity information ID and the domain name to the global load balancing domain name server GSLB-DNS12, and receives a first analysis result obtained by analyzing the domain name by the GSLB-DNS12 based on the logic network node ID, wherein the logic network node ID is sent by the GSLB-DNS12; the Access-DNS11 sends the first resolution result to the client 10. The high-precision domain name resolution scheduling supporting fine granularity division is realized by adding the logic network dots and the Access-DNS11, so that a user can obtain required contents nearby, and the Access speed is improved.
In a specific implementation, the invention realizes high-precision edge scheduling supporting fine granularity division by adding a logical network node concept and an Access-DNS11 device on the basis of DNS technology, the main components of the system are shown in figure 2, the Access-DNS11 is taken as a center, and a plurality of clients 10 interact with Local-DNS13 or GSLB-DNS12.
It should be noted that, in the embodiment of the present invention, the logical network node is a virtual network concept, that is, a combination of machines that can be grouped together.
The GSLB-DNS12 mainly supports the registration of logic network nodes, and the domain name is provided with high-precision scheduling, and provides the capability of configuring and responding to analysis values in different logic network nodes according to the domain name; local-DNS13 provides existing Local DNS services; the Access-DNS11 is used as a central server of the embodiment of the invention, can register a logic network node to the GSLB-DNS12, synchronously open a domain name scheduled with high precision, and then is used as an Access point for domain name resolution of the logic network node to receive all DNS requests in the logic network; the client 10, which may be a server, a container, a home computer, etc., belongs to a certain logical network node, and its DNS resolution points to Access-DNS11 under the logical network node.
As shown in fig. 3, the logic network node registration and activation of the high-precision dispatch service domain name process is as follows: 1) Firstly, requiring Access-DNS11 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 dispatching service domain name to the GSLB-DNS12 system; 4) The Access-DNS11 and the GSLB-DNS12 synchronously open domain name information of high-precision scheduling.
The request processing process of 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-DNS11; 2) The Access-DNS11 judges that the domain name is the domain name with the opened high-precision scheduling, injects the logic network node ID registered with the GSLB-DNS12 before, and initiates request resolution to the GSLB-DNS12; 3) The GSLB-DNS12 finds corresponding analysis configuration according to the domain name and the logic network node ID, and responds to the first analysis result to the Access-DNS11; 4) Access-DNS11 responds to the first resolution result to client 10.
The GSLB-DNS12 may perform resolution according to the previously registered logical network node ID sent by the Access-DNS11, that is, the logical network node ID has a mapping relationship with the first resolution result, for convenience of explanation, the following describes the internal modules of the GSLB-DNS 12:
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 a request from the Access-DNS11 and send the request to the DNS request processing module, and the DNS request sending module is configured to send a first resolution result processed by the DNS request processing module to the Access-DNS11. For the DNS request processing module, there is a mapping relationship between the logical network node ID and the first resolution result, as shown in the following table (table 1).
| Domain name | Logical network node ID | Analytical value |
| aaa.bbb.ccc | 1 | 192.168.0.1 |
| aaa.bbb.ccc | 2 | 192.168.0.2 |
| xxx.yyy.zzz | 1 | 192.168.0.3 |
TABLE 1
As can be seen from table 1, for each domain name, the GSLB assigns a logical network node ID to the GSLB, and for the same domain name, for example, aaa.bbb.ccc, there may be more than one logical network node ID, but the resolution value is unique for a group of domain names and logical network node IDs having a correspondence relationship, for example, for domain names aaa.bbb.ccc, if the GSLB assigns a logical network node ID of 1, the first resolution result (i.e., resolution value) is 192.168.0.1, and if the 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 logical network node ID of 1 corresponds to a path blocking, the GSLB may 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 realize one-stop configuration, ensures finer granularity, can effectively solve the congestion condition of the Internet network, and improves the response speed and the success rate of user access.
The DNS request processing module is mainly used for domain name resolution, and finds out the mapped resolution value configuration according to the domain name of the DNS request and the logic network node ID.
The request processing process of 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 high-precision scheduling; 2) The Access-DNS11 judges that the domain name is the domain name without high-precision scheduling, and directly passes the Local-DNS13 to request for resolution; 3) Local-DNS13 responds to the second analysis result to Access-DNS11; 4) The Access-DNS11 responds to the second resolution result to the client 10.
The Access-DNS11 needs to determine a domain name in the domain name resolution request sent by the client 10, if the domain name resolution 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 to perform domain name resolution through a mapping relationship, if the domain name resolution request is a non-high-precision scheduling domain name resolution request, the domain name resolution request is directly returned to the Local-DNS13, and the two resolution modes improve the resolution efficiency, so that in order to facilitate description on 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 an internal module of the Access-DNS 11:
Access-DNS11 comprises a DNS request receiving module, a DNS request processing module and a DNS request transmitting module.
The DNS request receiving module is configured 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.
The DNS request processing module stores a list of the domain names of the open high-precision dispatch services, as shown in the following table (table 2).
| The domain name of the high-precision dispatch service is opened |
| aaa.bbb.ccc |
| xxx.yyy.zzz |
TABLE 2
The DNS request processing module may determine, according to a domain name resolution request sent by the client 10, whether the domain name is in a list of domain names that have been opened with high-precision dispatch services, if not, directly mark Local, and send the Local to the DNS request sending module; if yes, the logic network node ID is injected into NSID of pseudo resource record OPT of EDNS, marked as gslb, and sent to DNS request sending module.
The DNS request transmitting module stores the address of Local-DNS 13: 192.168.0.1, if marked as Local, sent to Local-DNS13; if the label is GSLB, the label is sent to the GSLB-DNS12.
