Description

Technical Field

[0001] The present disclosure relates to the field of data processing technology, and in particular to a DNS resolution method, a DNS resolution device, a storage medium, and an electronic device. Background Art

[0002] DNS (Domain Name System) is a service of the Internet. It is a distributed database that maps domain names and IP addresses to each other, making it easier for people to access the Internet. Network requests are resolved by DNS to obtain one or more IP addresses, and then a connection is established through the IP addresses.

[0003] At present, there are two common DNS resolution optimization solutions: client IP tracking and server IP tracking. Client IP tracking means that the client adds or subtracts weights on the IP addresses obtained by DNS resolution, re-sorts them according to the weights, and gives priority to IP addresses with high weights. However, this method has the risk of being hijacked, and when access to IPs fails in a certain area, it will not be possible to update the IP in time and fix the network failure. Server IP tracking means that the server accesses the IP through a self-built DNS resolution server, sets different weights according to the success rate, and re-sorts and issues them according to the weights. Under this method, the result of the server accessing the IP may not be the same as the result of the client accessing the IP, resulting in the IP sent being not necessarily the optimal IP.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more comprehensive and complete and will fully convey the concept of the example embodiments to those skilled in the art.

[0032] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the present disclosure.

[0033] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0034] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0035] Network requests will be resolved by DNS to obtain one or more IP addresses, and then establish a connection through the IP addresses. Currently common DNS resolution optimization solutions are:

[0036] Solution 1: Client IP Ranking: The client adds or subtracts weights on the IP addresses obtained through DNS resolution, reorders them according to weights, and gives priority to IP addresses with higher weights.

[0037] Solution 2: Server-side IP tracking: Use a self-built DNS resolution server to access the IP on the server side, set different weights based on the success rate, and re-sort and distribute them according to the weights.

[0038] Solution 1 has the following problems: the DNS resolution data may come from the system DNS resolution, which may be hijacked, and may cause the interface request to fail or access a malicious website; the client's region and network environment may not be suitable for the current network weight ranking, which may cause the interface request to fail or take a long time to complete; when access IP fails in a certain area, there is a problem that the IP cannot be updated in time to repair the network failure.

[0039] Solution 2 has the following problems: the result of the server accessing the IP may not be the same as the result of the client accessing the IP, resulting in the IP sent being not necessarily the optimal IP; the server network environment is different from the client IP environment, and the IP address that the server can access may not be accessible to the client in a different network environment. For example, when accessing the server room of China Telecom under the Unicom network of the car computer, access failure may occur.

[0040] Therefore, the present disclosure proposes a DNS resolution method to solve one or more of the above problems in order to combine more network feature data of the client in the prior art so that the DNS resolution results can respond to exceptions more quickly and provide better resolution results.

[0041] The implementation details of the technical solution of the embodiment of the present disclosure are elaborated in detail below.

[0042] Figure 1 The following is a schematic diagram showing a flow chart of a DNS resolution method in an exemplary embodiment of the present disclosure. Figure 1 As shown, the DNS resolution method is applied to the server, including steps S101 to S107:

[0043] Step S101, obtaining local diagnostic data reported by each client;

[0044] Step S103, performing information aggregation analysis on the local diagnostic data according to preset dimensions to obtain a diagnostic analysis result;

[0045] Step S105, in response to the target interface call request initiated by the target client, obtaining DNS configuration content based on the diagnostic analysis result;

[0046] Step S107: returning the DNS configuration content to the target client, so that the target client parses the DNS configuration content to determine the IP information.

[0047] In the technical solutions provided by some embodiments of the present disclosure, after pre-collecting the local diagnostic data reported by each client, information aggregation analysis is performed to obtain the diagnostic analysis results, and then when the client performs DNS resolution service, the DNS configuration content sent by the self-built DNS server is obtained through the target interface to obtain the IP information of the specified domain name, and then the client can access the correct access link through the DNS. In this way, the method of dynamically adjusting the network configuration through local network quality diagnosis combined with cloud resolution can bring lower network latency, better network request success rate, and thus better improve the user experience.

[0048] Below, each step of the DNS resolution method in this example implementation will be described in more detail with reference to the accompanying drawings and embodiments.

[0049] In step S101, local diagnostic data reported by each client is obtained.

[0050] Specifically, when a client network request fails, the client performs network diagnosis and reports local diagnostic data to the server after diagnosis.

[0051] In step S103, the local diagnostic data is subjected to information aggregation analysis according to preset dimensions to obtain a diagnostic analysis result.

[0052] Specifically, the server can store local diagnostic data in a database, and then aggregate and analyze the information according to different dimensions to conduct a secondary analysis of what went wrong.

[0053] Figure 2 A schematic diagram schematically shows a network connection in an exemplary embodiment of the present disclosure. Figure 2 As shown in the figure, network connections are roughly divided into network connections between each client (i.e., Actor in the figure, which can also be recorded as a user) and each router, network connections between each router and each operator, and network connections between each operator and each cloud service. That is, the client's access to the cloud service (based on the domain name) may pass through different routers and operators to reach the target server.

[0054] When a client's network request fails, only the problem of the client itself is reported. When the server collects local diagnostic data sent by multiple clients, it can aggregate the diagnostic information, evaluate all problematic nodes, and determine the part of the network where the abnormality occurs. Then, through the DNS distribution, the user end can use the correct access link to improve the user experience.

[0055] Preset dimensions can be pre-configured, such as network channels (which can be broken down into network channels between routers and operators, network channels between operators and cloud services, etc.), clients, routers, operators, cloud services, etc. for aggregate analysis.

[0056] In step S105, in response to the target interface call request initiated by the target client, the DNS configuration content is obtained based on the diagnosis and analysis result.

[0057] When the client initiates a new network connection, the client calls the target interface to obtain the current DNS configuration content, which is obtained based on the diagnostic analysis results.

[0058] In one embodiment of the present disclosure, obtaining the DNS configuration content based on the diagnostic analysis result includes: determining abnormal IP information based on the diagnostic analysis result; and removing the abnormal IP information from the initial DNS configuration content as the DNS configuration content.

[0059] Specifically, when the server can determine the abnormal IP information based on the diagnostic analysis results, it can then remove the abnormal IP information through DNS delivery, allowing the user to use the correct access link, thereby improving the user experience.

[0060] When the diagnostic analysis result is that the network channel between the operator and the cloud service is abnormal, the DNS configuration content is obtained based on the diagnostic analysis result, including: determining the abnormal operator and abnormal cloud service corresponding to the network channel abnormality based on the diagnostic analysis result, and determining the abnormal IP information corresponding to the abnormal cloud service; removing the abnormal IP information from the initial DNS configuration content corresponding to the abnormal operator as the DNS configuration content.

[0061] Figure 3 A schematic diagram of configuring DNS configuration content when a network channel is abnormal in an exemplary embodiment of the present disclosure is schematically shown. Taking the network channel abnormality between the operator and the cloud service as an example, first identify the characteristics, statistically analyze the local diagnostic data of the access abnormality, and identify the abnormal users (i.e., the Actors in the figure) based on the client IP as clients concentrated in the network segment of operator A. Then get the processing strategy, judge that there is an abnormality in the network channel from operator A to cloud service 1, and for the affected users, i.e., users in the network segment of operator A, the DNS service resolution content sent down no longer contains the problematic IP_1.

[0062] When the diagnostic analysis result is that the cloud service is abnormal, the DNS configuration content is obtained based on the diagnostic analysis result, including: determining the abnormal cloud service based on the diagnostic analysis result, and determining the abnormal IP information corresponding to the abnormal cloud service; removing the abnormal IP information from the initial DNS configuration content corresponding to each operator as the DNS configuration content.

[0063] Figure 4 A schematic diagram of configuring DNS configuration content when a cloud service is abnormal in an exemplary embodiment of the present disclosure is schematically shown. Taking cloud service abnormality as an example, first identify the characteristics, statistically analyze the local diagnostic data of the reported access abnormality, and analyze that the abnormal clients generally have the problem of high RT. Based on the user domain name resolution IP, the users (i.e., the Actors in the figure) are all concentrated in the cloud service DNS resolution IP as IP_1. Then get the processing strategy, judge that there is a problem with the cloud service itself, and need to remove its external services. For all users, remove the result of DNS resolution of IP_1, and let users access IP_2.

[0064] Step S107: returning the DNS configuration content to the target client, so that the target client parses the DNS configuration content to determine the IP information.

[0065] Specifically, the server sends DNS configuration content without any abnormality, and returns the DNS configuration content to the client, so that the client can use the correct access link and improve the user experience.

[0066] Figure 5 The flowchart of another DNS resolution method in the exemplary embodiment of the present disclosure is schematically shown. Figure 5 As shown, the DNS resolution method is applied to the client, including steps S501 to S507:

[0067] Step S501, when a network request fails, network diagnosis is performed to obtain local diagnostic data;

[0068] Step S503, reporting the local diagnostic data to the server, so that the server performs aggregate analysis based on the local diagnostic data reported by each client to obtain a diagnostic analysis result;

[0069] Step S505, in response to the network request, calling the target interface to obtain the DNS configuration content returned by the server based on the diagnosis and analysis result;

[0070] Step S507: parsing the DNS configuration content to determine the IP information.

[0071] Specifically, in step S501, when the client network request fails, network diagnosis is performed to obtain local diagnostic data, such as whether the vehicle computer is connected to the network, the public network IP of the vehicle computer, the target IP of the network request, and Traceroute.

[0072] Among them, car computer refers to the abbreviation of the in-vehicle infotainment product installed in the car. The car computer can functionally realize information communication between people and cars, cars and the outside world, or cars and cars; Traceroute is a network command under the Linux system, which uses the ICMP protocol to locate all router information between the current computer and the target computer.

[0073] In step S505, when the client performs DNS resolution in response to the network request, the DNS configuration content returned by the server is obtained through the target interface during resolution.

[0074] In step S507, the DNS configuration content is parsed to obtain the IP information of the specified domain name.

[0075] In one embodiment of the present disclosure, after determining the IP information, the method further includes: sorting each IP address in the IP information based on the local diagnostic data.

[0076] In one embodiment of the present disclosure, after the anomaly is resolved and restored, active or passive recovery can be adopted. Active means combining the operation and maintenance feedback of the faulty node, and restoring the original DNS configuration after the problem is solved; passive means periodically trying to send configuration to individual users to detect whether the problem has been restored. At this time, it is necessary to cooperate with the user-side application to sniff the abnormal recovery situation.

[0077] Figure 6 The following is a schematic diagram showing the data flow of a DNS resolution method in an exemplary embodiment of the present disclosure. Figure 6 As shown, this solution needs to be processed together with the client and the server.

[0078] On the client side, the client initiates a network request, for example, the vehicle computer initiates a network request, which is resolved through DNS and determines whether the network request is successful. If it is not executed successfully, network diagnosis is performed, and then the diagnostic information is reported to the server for secondary analysis. When the client initiates a network request again, the custom DNS resolution service is used to resolve the network request. During resolution, the self-built DNS server is used to obtain the IP information of the specified domain name through the interface, and the IP is sorted in combination with the local diagnostic results.

[0079] On the server side, the local diagnostic data uploaded by the client is recorded and analyzed, and stored in the database. Information aggregation analysis and optimization are performed according to different dimensions, and finally the DNS configuration content is obtained for the next round of DNS resolution.

[0080] Based on the above method, the method of dynamically adjusting the network configuration through local network quality diagnosis combined with cloud analysis can bring lower network latency and better network request success rate.

[0085] The return module 704 is used to return the DNS configuration content to the target client, so that the target client determines the IP information according to the DNS configuration content.

[0086] According to an exemplary embodiment of the present disclosure, the configuration module 703 is used to determine abnormal IP information based on the diagnosis and analysis result; and remove the abnormal IP information from the initial DNS configuration content as the DNS configuration content.

[0087] According to an exemplary embodiment of the present disclosure, the configuration module 703 is also used to determine the abnormal operator and abnormal cloud service corresponding to the network channel abnormality based on the diagnostic analysis result when the diagnostic analysis result is that the network channel between the operator and the cloud service is abnormal, and determine the abnormal IP information corresponding to the abnormal cloud service; remove the abnormal IP information from the initial DNS configuration content corresponding to the abnormal operator as the DNS configuration content.
