Description

Technical Field

[0001] This application relates to the field of Internet technology, and in particular to a domain name query method, apparatus, computer equipment, and storage medium. Background Technology

[0002] DNS (Domain Name System) is managed on a zone basis. Except for the root zone, the authoritative server of each zone can be accessed by the client in the recursive process after registering the authorization information in the parent zone.

[0003] Since each region may have multiple authoritative servers, after obtaining authorization information, the client first attempts to access the corresponding authoritative server based on the server address recorded in the record set. Then, it sorts the authoritative servers according to their response latency, ultimately determining the authoritative server with the fastest response. This selection process can lead to an imbalance in the load across multiple authoritative servers. Summary of the Invention

[0073] Figure 4 An internal structural diagram of a computer device provided in an embodiment of the present invention. Detailed Implementation

[0074] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0075] The domain name lookup method provided in this application can be applied to, for example... Figure 1In the application environment shown, client 1 communicates with server 2 via a network. First, client 1 sends a domain name query request to server 2. Upon receiving the request, server 2 determines whether the request contains a redirection information record. If a redirection information record is present, server 2 responds to the domain name query request, obtaining a response result. This response result includes the redirection information record and its corresponding redirection information record value. Then, server 2 sends the response result back to client 1. Finally, client 2 obtains the final response result for the domain name query based on the response result. Client 1 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. Server 2 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0076] In one embodiment, such as Figure 2 As shown, a domain name query method is provided, which can be applied to... Figure 1 Taking the server in the example, the following steps are included:

[0077] Step S101: Obtain the domain name query request sent by the client.

[0078] Domain name query requests can carry routing information records. These records are used to negotiate between the client and server, allowing the client to choose which node in the server cluster to guide, thus enabling dynamic load balancing. During this process, the server sends routing information aligned with load balancing to the client, and the client, wanting its query requests to be processed more smoothly, tends to follow the guidance from the origin server. Each routing information record has a corresponding value, which can be empty. In one embodiment, Extended DNS (EDNS) can be used to support the implementation of routing information records. Specifically, the routing information record is an .opt pseudo-resource record that can transmit the data required for negotiation between the server and client.

[0079] A guidance information record entry may include multiple fields, each defining a record entry. In some embodiments, the guidance information record entry includes a load level record entry, where the guidance information record value includes the load level. This load level record entry indicates the server's load level, which can be: low load, medium load, high load, abnormal load, or client load, etc. The load level is determined based on the server's load value information. In some embodiments, the load value information includes the server's processing capacity for domain name query requests, the average processing capacity consumed over a preset time period, the total amount of necessary resources, and / or the availability of necessary resources, etc. Specifically, a load value can be obtained by incorporating weights into the above load information, and then the load level can be determined based on the relationship between the load value and a load threshold. For example, when the load value is greater than a first preset load value, it is set to high load. When the load value is not greater than the first preset load value and not less than a second preset load value, it is set to medium load. When the load value is less than the second preset load value, it is set to low load. It should be noted that the second preset load value is less than the first preset load value. The above load levels will be synchronized to the DNS resolution process, facilitating the server to subsequently encapsulate the specific load level into the load level record entry.

[0080] In some embodiments, the guidance information record may further include a sorting record for sorting servers in the server cluster, a guidance path information record, and / or a signature information record. Correspondingly, the guidance information record value includes: a sorting table, guidance path information, and / or signature information.

[0081] The redirection path information record includes the source server, client, preferred server address, and valid expiration timestamp. The preferred server address is a designated server address assigned by the server to the new server to which the client is redirected. This means that subsequent domain name queries will preferentially be performed on this preferred server. This preferred server address is dynamically set for the client based on the load values ​​of each server, and is inversely proportional to the overall load value.

[0082] The signature information record is used to sign the aforementioned navigation path information to verify the reliability of the data source.

[0083] This sorting table can be a list of server addresses in a server cluster. The sorting of this address list can be configured based on the load of each server, for example, arranging the server addresses from lowest to highest load. That is, servers at the beginning of the list have lower loads, and servers at the end have higher loads. In some embodiments, the load information of each server in the server cluster is periodically used to sort the servers. An algorithm can be used to derive the sorting result based on the load value and synchronize it to the DNS resolution process. When a client cannot preferentially select a preferred server for a domain name query, it can select a server from this sorting table for the query.

[0084] Step S102: Determine whether the domain name query request has a redirection information record.

[0085] Determine whether the domain name query request has the aforementioned redirection information record. If the domain name query request has the redirection information record, proceed to step S103. If the domain name query request does not have the redirection information record, proceed to responding to the domain name query request based on the current server load. If the current server load is not greater than a preset load threshold, obtain domain name response data to respond. If the current server load is greater than the preset threshold, obtain domain name rejection response data (REFUSED) and send it to the terminal, facilitating subsequent domain name queries to other servers by the terminal.

[0086] Step S103: In response to the domain name query request having a navigation information record item, respond to the domain name query request and obtain a response result. The response result includes a navigation information record, which is encapsulated in the navigation information record item.

[0087] In some embodiments, the step of responding to a domain name query request and obtaining a response result includes:

[0088] The target guidance information record value is determined based on the current server load.

[0089] The target guidance information record value is used to set the guidance information record value corresponding to the guidance information record item in order to generate the response result.

[0090] The target orientation information record value is the negotiation data returned by the current server to the client. This value can be determined by comparing the current server load with a load threshold.

[0091] First, determine if the current server load is below a first preset load threshold. If it is below the first preset load threshold, obtain the target load level of the current server and set the record value corresponding to the load level record item using the target load level value. If it is not below the first preset load threshold, obtain the target load level, routing path information, target signature information, and target sorting table. Then, set the record value of the load level record item using the target load level, set the record value of the routing path information record item using the target routing path information, set the record value of the signature information record item using the target signature information, and set the record value of the sorting record item using the target sorting table.

[0092] Assuming the target load level of the current server is below a first preset load threshold, it can be considered a low load. If it is not lower than the first preset load threshold, it can be considered a medium or high load. When the target load level of the current server is low, simply encapsulate the low load in the load level record. It should be noted that when the client receives this load level record, after parsing it and obtaining "low load," it will ignore this load level record. When the target load level of the current server is medium or high, the load level record, routing path information record, signature information record, and sorting record are encapsulated.

[0093] Furthermore, the guidance information record value includes the initial signature information corresponding to the signature information record item. After determining whether the current server load is lower than the first preset load threshold, it also includes:

[0094] In response to a load not lower than a first preset load threshold, determine whether the load of the current server is not lower than a second preset load threshold, wherein the second preset load threshold is greater than the first preset load threshold.

[0095] In response to a load threshold not lower than the second preset threshold, the initial signature information is verified.

[0096] Upon successful verification of the initial signature information, the domain name response data is retrieved to generate the response result.

[0097] Furthermore, the guidance information record value also includes the guidance path information record value corresponding to the guidance path information record item. In response to the initial signature information passing verification, the step of obtaining domain name response data to generate a response result includes:

[0098] In response to the initial signature information being verified, it is determined whether the navigation path information record value matches the preset navigation path information record value.

[0099] In response to a match between the redirection path information record value and the preset redirection path information record value, domain name response data is obtained to generate a response result.

[0100] Furthermore, in response to a match between the redirection path information record value and a preset redirection path information record value, the step of obtaining domain name response data to generate a response result includes:

[0101] In response to a match between the recorded value of the guidance path information and the preset recorded value of the guidance path information, it is determined whether the recorded value of the guidance path information is within the validity period.

[0102] If the redirection path information record value is within its validity period, retrieve the domain name response data to generate a response result.

[0103] When the current server load is not lower than the first preset load threshold and lower than the second preset load threshold, the current server load can be considered medium load. At this time, the server can obtain domain name response data to respond to domain name query requests. When the current server load is not lower than the second preset load threshold, the current server load can be considered high load. At this time, due to the excessively high load, there is a risk of a large backlog of requests that cannot be processed in a timely manner. Therefore, the current server needs to determine whether to prioritize processing this domain name query request. Specifically, this can be determined by verifying the matching and validity of the initial signature information and the redirection path information record values.

[0104] Specifically, the validity of the signature information can be verified using the source server's public key. Servers in the cluster possess each other's public keys. Verification can be performed on client information and the destination server; if the client information matches a preset client and the destination server is the current server, the verification is considered successful.

[0105] In some embodiments, if either the initial signature information or the verification of the matching and validity of the routing path information record value fails, the current server will ignore the domain name query request and treat it as a general request.

[0106] Step S104: Send the response result to the client so that the client can obtain the final response result of the domain name query based on the response result.

[0107] Specifically, the client checks the validity period of the redirection information record value. If the validity period has expired, the client will clear the record value and use preset logic to select the target server for domain name lookup. If the validity period has not expired, the final response result will be obtained based on the redirection information record value.

[0108] In some implementations, when the client and server system times differ significantly, causing the client to believe the server is still valid even though it has expired, the server will still fill in "abnormal load level" in the load level record, without updating other fields. When the client receives the "abnormal load level" message, it will attempt to synchronize with the standard time and continue the domain name lookup.

[0109] In the above domain name query method, the domain name query is negotiated by setting a guidance information record item between the client and the server. This is beneficial for selecting a server with a suitable load in the server cluster, so that the load of the servers in the cluster is more balanced.

[0110] It should be understood that, although Figure 2 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 2 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.
