Description

Server, data processing method and medium

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office, the application number is 202011084472.1, and the invention title is "a server, data processing method, device and medium" on October 12, 2020, the entire content of which is incorporated by reference In this application.

Technical field

This application relates to the field of computer communication, and in particular to a server, a data processing method and a medium.

Background technique

In related technologies, the DNS server saves the corresponding relationship between the resolution result such as the IP address and the domain name. According to the corresponding relationship between the resolution result and the domain name, the target resolution result corresponding to the domain name carried in the received resolution request can be determined, so that the target The analysis result is fed back to the user's smart device.

In an actual application scenario, Figure 1 is a schematic diagram of a scenario where an existing server processes a domain name. As shown in Figure 1, the user’s smart device initiates a resolution request to a server provided by the network operator or other public servers, for example, a resolution request for querying the IP address of www.example.com. After receiving the resolution request, the server obtains The domain name carried in the resolution request is queried according to the domain name whether the resolution result corresponding to the domain name is stored. If the resolution result corresponding to the domain name is saved and the validity period corresponding to the resolution result has not expired, the server sends the obtained resolution result to the smart device; otherwise, it forwards the resolution request to other pre-configured servers, such as a recursive DNS server, Iteratively forwards to the root server through other DNS servers, and iteratively forwards to authoritative servers at all levels through other DNS servers to obtain the resolution results of the domain name carried in the resolution request by other servers, and send the obtained resolution results to the smart device and locally The domain name and its corresponding resolution result are cached, so that when a resolution request carrying the domain name is received again later, the cached resolution result corresponding to the domain name can be directly sent to the smart device to improve the response efficiency of the smart device.

Among them, when other servers feed back the resolution result, they will also feed back the validity period (TTL) corresponding to the resolution result. When the resolution request sent by the smart device carrying the domain name is received again, the server determines that the resolution result corresponding to the domain name exceeds After the validity period, the resolution result corresponding to the domain name will be deemed invalid, and the resolution result corresponding to the domain name needs to be queried from other servers, and the resolution result corresponding to the domain name sent by other servers is sent to the smart device.

For the above processing method, when the resolution result corresponding to a certain domain name cached by the server expires, and other servers fail, the server will not be able to obtain the resolution results of the domain name fed back by other servers in time, and has been waiting for feedback from other servers. As a result of the resolution of the domain name, the server cannot respond to the resolution request in a timely manner, which reduces the server’s response efficiency and user experience.

Detailed ways

In order to improve the response efficiency of the server to the parsing request and improve the user experience, this application provides a server, a data processing method, and a medium.

In order to make the objectives, technical solutions, and advantages of the application more clear, the application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

In actual use, the user's smart device initiates a resolution request to a server provided by the network operator or other public servers, for example, a resolution request to query the IP address of www.example.com. After the server receives the resolution request for resolving a certain domain name sent by the smart device, it performs corresponding processing on the resolution request, and obtains the domain name information carried in the resolution request. In order to quickly forward the resolution results corresponding to some domain names to smart devices, the server pre-caches the resolution results corresponding to some domain names and their corresponding expiration dates. After obtaining the resolution results in the resolution request, the domain name is resolved with the cached ones. The domain name of the result is matched. When there is a matching domain name, it is determined whether the validity period corresponding to the target resolution result corresponding to the matched domain name has expired. If it is determined that the validity period corresponding to the target resolution result has expired, you can first contact other servers Send the analysis result. According to whether the resolution result of the domain name sent by other servers is received within the preset first time period, it is determined whether to directly send the target resolution result.

Fig. 2 is a schematic diagram of a data processing process provided by some embodiments of the present application, and the process includes:

S201: Receive a first resolution request, and obtain domain name information carried in the first resolution request.

In this application, the data processing method provided in this application is applied to the server.

In the actual application process, when a user wants to access a certain website through a certain registered domain name, he can obtain the IP address of a certain page of a certain website by entering the domain name, so as to achieve the purpose of visiting a certain website. After receiving the domain name input by the user, the smart device generates a corresponding first resolution request according to the domain name, and sends the generated first resolution request to a server provided by the network operator or other public servers. After receiving the first resolution request, the subsequent server obtains the domain name information carried in the first resolution request through corresponding processing. Then, based on the data processing method provided in this application, corresponding processing is performed on the information of the domain name, so as to realize the response to the first resolution request.

Wherein, the first analysis request received by the server may be an analysis request sent by a smart device, or may be an analysis request sent by a smart device forwarded by a lower-level server.

S202: Determine that the target resolution result corresponding to the domain name is cached locally, and the validity period corresponding to the target resolution result has expired, then forward the first resolution request to another server.

S203: Determine that the resolution result of the domain name sent by the other server is not received within a preset first time period, and send the target resolution result.

In actual application scenarios, it is relatively rare to modify the resolution result corresponding to a domain name, for example, modify the IP address corresponding to a domain name, etc., so that the resolution result of the domain name obtained by re-querying other servers is most often It's the same as before. Therefore, in order to facilitate subsequent smart devices to obtain the resolution results of the visited domain names in time, the server can cache the received resolution results of a certain domain name sent by other servers, so that the second resolution carrying the domain name can be subsequently received again. When requesting, directly send the locally cached resolution result of the domain name to improve the efficiency of responding to the resolution request.

In order that the server can no longer continue to send the locally cached target resolution result corresponding to the domain name when the resolution result of a certain domain name changes, that is, send the wrong resolution result, which affects the subsequent business access of the smart device, other servers are giving When the server sends the resolution result of any domain name, it will also send the validity period corresponding to the resolution result. After the server receives the resolution result of the domain name and the validity period corresponding to the resolution result, it caches the resolution result of the domain name, the time when the resolution result is received, and the validity period corresponding to the resolution result, and requests the resolution of the domain name on the subsequent smart device As a result, according to the time when the resolution request is received and the validity period corresponding to the resolution result, determine whether the validity period corresponding to the resolution result of the domain name has expired, so that it can be forwarded to other servers when the validity period corresponding to the resolution result has expired The received first resolution request is used to update the locally cached resolution result corresponding to the domain name according to the resolution result of the domain name sent by other servers.

Among them, the method of determining whether the validity period corresponding to the resolution result of the domain name has expired according to the time when the resolution request is received and the validity period corresponding to the resolution result includes:

Method 1: Start timing when receiving the analysis result. Subsequently, it is determined whether the time period recorded by the timer when the resolution request is received is greater than the validity period corresponding to the resolution result, and it is determined whether the validity period corresponding to the resolution result of the domain name expires. If it is greater than, it is determined that the validity period corresponding to the resolution result of the domain name has expired; otherwise, it is determined that the validity period corresponding to the resolution result of the domain name has not expired.

Method 2: When receiving the analysis result, count down from the validity period corresponding to the analysis result. It is subsequently determined whether the remaining time recorded by the timer is 0 when the resolution request is received, and it is determined whether the validity period corresponding to the resolution result of the domain name has expired. If so, it is determined that the validity period corresponding to the resolution result of the domain name has expired; otherwise, it is determined that the validity period corresponding to the resolution result of the domain name has not expired.

Method 3: When the analysis result is received, the valid time range is determined according to the current time when the analysis result is received and the validity period corresponding to the analysis result. Subsequently, it is determined whether the time when the resolution request is received is within the valid time range, and it is determined whether the validity period corresponding to the resolution result of the domain name has expired. If so, it is determined that the validity period corresponding to the resolution result of the domain name has expired; otherwise, it is determined that the validity period corresponding to the resolution result of the domain name has not expired.

For the above method, once other servers fail or deny server access, it is easy to cause the server to wait for other servers to feed back the resolution result of the domain name, so that it cannot continue to respond to the user's first resolution request, and then access the user's subsequent services. Make an impact.

In a possible implementation manner, in order to respond to the first resolution request in time, after obtaining the domain name information carried in the first resolution request, the domain name is matched with the domain name for which the resolution result has been cached. Domain name, determine whether the validity period corresponding to the target resolution result corresponding to the matched domain name has expired, if it is determined that the validity period corresponding to the target resolution result has expired, send the target resolution result, and forward the first resolution request to Other servers update the current locally cached target resolution result and the validity period corresponding to the target resolution result.

Through the above method, although the server can respond to the user's first resolution request in time, and in most cases, the target resolution result cached locally by the server is also correct, but once the resolution result of a certain domain name changes, and When other servers can respond normally, the server directly sends the locally cached target resolution result corresponding to the domain name, which will cause the smart device to perform subsequent business processing according to the target resolution result, which affects the user's subsequent business access. Therefore, in order to respond to the first resolution request in a timely manner and ensure the accuracy of the resolution result of the domain name sent to the smart device as much as possible, in this application, it is determined that the target resolution result corresponding to a certain domain name is cached locally, and the After the validity period corresponding to the target resolution result has expired, first forward the first resolution request to other servers, and determine how to respond to the smart device according to whether the domain name resolution results sent by other servers are received within the preset first time period The first resolution request.

In the specific implementation process, if it is determined that the analysis result of the domain name sent by the other server is not received within the preset first time period, indicating that there may be network delays or other server failures, etc., the target analysis result is sent first.

Wherein, if the first resolution request is sent by a smart device, when it is determined that the resolution result of the domain name sent by the other server is not received within the preset first time period, the target resolution result is sent to the smart device; The result is forwarded by the lower-level server, and when it is determined that the resolution result of the domain name sent by the other server is not received within the preset first time period, the target resolution result is sent to the lower-level server.

S204: If it is determined that the resolution result of the domain name sent by the other server is received within the preset first time period, send the resolution result of the domain name.

In a possible implementation manner, in order to ensure the accuracy of the server's response to the first resolution request, in this application, if it is determined that the resolution result of the domain name sent by another server is received within the preset first time period, it means that the current other The server works normally, and in order to ensure that it accurately responds to the first resolution request, it sends the received resolution results of the domain name sent by other servers.

Wherein, if the first resolution request is sent by a smart device, it is determined that the resolution result of the domain name sent by the other server is received within the preset first time period, and the resolution result of the domain name is sent to the smart device; The resolution result is forwarded by the lower-level server, and when it is determined that the resolution result of the domain name sent by the other server is received within the preset first time period, the resolution result of the domain name is sent to the lower-level server.

In this application, when setting the first duration, it can be determined based on experience, or it can be set to a different value according to different scenarios. If you want to ensure the efficiency of the server in responding to the first resolution request, you can set the preset first time length to be shorter. If you want to avoid that the first time length is set too short, the domain name resolution results normally sent by other servers cannot be sent. , You can set the preset first duration longer. Preferably, it can be set according to the statistics of the duration of normal interaction between each other server and the server.

In order to accurately determine whether other servers may fail, on the basis of the foregoing embodiment, in this application, determining that the domain name resolution result sent by the other server is not received within the preset first time period includes:

Receiving failure response information sent by the other server within the preset first time period; or

The response information sent by the other server is not received within the preset first time period, and the response information is success response information or failure response information, wherein the success response information carries the resolution of the domain name result.

In actual application scenarios, network delays, other server failures, etc. may occur, so that the server cannot receive the domain name resolution results sent by other servers within the preset first time period. Specifically, when a network delay occurs, it may cause communication delays between other servers and servers, so that the server cannot receive the domain name resolution results sent by other servers within the preset first time period; when a network failure occurs, It will make it impossible to establish a communication connection between other servers and the server, so that the server cannot receive the resolution results of the domain name sent by other servers within the preset first time period; when other servers fail, the server may not be able to It is assumed that within the first time period, the resolution result of the domain name sent by other servers or the failure response information sent by other servers, such as SERVFAIL, REFUSED, etc., are received. Based on this, in this application, the server determines that the domain name resolution result sent by other servers is not received within the preset first time period, including the following situations:

Case 1: If the failure response message sent by other servers is received within the preset first time period, it means that other servers may be faulty and cannot be recovered temporarily, then it is determined that the domain name sent by other servers is not received within the preset first time period The result of the analysis.

Case 2: If the response information sent by other servers is not received within the preset first time period, that is, the success response information or the failure response information sent by other servers cannot be received within the preset first time period, it is determined to be in the preset first time period. The domain name resolution result sent by other servers is not received within the first time period.

Among them, the successful response message carries the resolution result of the domain name, such as NOERROR, NXDOMAIN, etc.

When based on the foregoing situation, it is determined that the resolution result of the domain name sent by other servers is not currently received within the preset first time period, the server directly sends the locally cached target resolution result.

Further, there may be network delays, or other server processing tasks may result in failure to process the first analysis request sent by the server within the preset first time period, etc., so that the server cannot receive other servers within the preset first time period. The resolution result of the sent domain name, and after sending the locally cached target resolution result, the resolution result of the domain name sent by other servers is received. In order to ensure the accuracy of the server's response to the first resolution request when the smart device subsequently makes the first resolution request for the domain name again, after the server sends the locally cached target resolution result, if it receives the resolution of the domain name sent by other servers As a result, the locally cached target resolution result corresponding to the domain name will be updated according to the currently received resolution result of the domain name sent by other servers. Specifically, after sending the target analysis result, the method further includes:

When receiving the resolution result of the domain name sent by the other server, update the target resolution result according to the resolution result.

In actual application scenarios, when other servers send the resolution result of the domain name to the server, they will generally also send the validity period corresponding to the resolution result to the server, so that the server can monitor the update time of the resolution result and request the domain name from other servers in time. The resolution result is to update the locally cached target resolution result according to the resolution result of the domain name sent by other servers, so as to improve the accuracy of subsequent response to the resolution request of the domain name. Therefore, in this application, after receiving the resolution result corresponding to the domain name and the validity period corresponding to the resolution result, the target resolution result is updated according to the resolution result, and the validity period corresponding to the target resolution result is performed according to the validity period corresponding to the resolution result. Update. Specifically, the receiving the resolution result of the domain name sent by the other server includes:

Receiving the resolution result corresponding to the domain name and the validity period corresponding to the resolution result;

The updating the target analysis result according to the analysis result includes:

The target analysis result is updated according to the analysis result, and the validity period corresponding to the target analysis result is updated according to the validity period corresponding to the analysis result.

In order to update the target resolution result in time, on the basis of the foregoing embodiments, in this application, the receiving the resolution result of the domain name sent by the other server includes:

Receiving the resolution result of the domain name sent by the other server within the preset second time period; or

It is determined that the resolution result of the domain name sent by the other server is not received within the preset second time period, and the first resolution request is sent to the other server at a preset time interval until the other server is sent The result of the resolution of the domain name.

In actual application scenarios, due to possible network delays or many other tasks currently processed by other servers, the first parsing request cannot be processed within the preset first time period, but when the network is not delayed or other servers have completed processing With the first resolution request, the server does not need to send the first resolution request to other servers again, and it can still receive the resolution result of the domain name sent by other servers. Therefore, in order to prevent the server from frequently forwarding the first analysis request to other servers, in this application, a second duration is preset. The server may determine whether the resolution result of the domain name sent by the other server is received within the second preset time period after it has not received the resolution result of the domain name sent by the other server within the preset first time period. If the resolution result of the domain name sent by another server is received within the second preset time period, the locally cached target resolution result is directly updated according to the received resolution result of the domain name.

In a possible implementation, there may be network failures, other server failures, etc., so that other servers cannot normally receive the first resolution request forwarded by the server, or send the resolution result of the domain name to the server. Therefore, in order to obtain timely The other server sends the resolution result of the domain name to improve the accuracy of the subsequent response to the first resolution request carrying the domain name. In this application, if the resolution result of the domain name sent by the other server is not received within the second preset time period , Then no longer wait for the resolution result sent by other servers to the domain name carried in the first resolution request that was forwarded last time, and forward the first resolution request to other servers at a preset time interval until it receives the name of the domain name sent by other servers. The resolution result is to update the locally cached target resolution result according to the received resolution result of the domain name.

If the resolution result of the domain name sent by the other server is not received within the preset second time period, the method further includes:

If the second resolution request carrying the domain name is received within the preset third time period, the target resolution result is directly sent.

In another possible implementation manner, in order to avoid frequently forwarding the first resolution request to other servers, causing heavy load pressure on other servers, after the domain name resolution results sent by other servers are not received within the preset second time period If the server receives the second resolution request carrying the domain name again within a period of time after the preset second duration, it will not forward the second resolution request to other servers, and directly send the locally cached domain name corresponding to the domain name. Target analysis result. Therefore, in this application, a third duration is preset. After the resolution result of the domain name sent by other servers is not received within the preset second time period, if the second resolution request carrying the domain name is received within the preset third time period, the locally cached target resolution result is directly sent.

When the server receives the resolution result of the domain name sent by other servers, it also receives the validity period corresponding to the resolution result sent by other servers. The server updates the locally cached target resolution result according to the received resolution result of the domain name. , And update the validity period corresponding to the locally cached target analysis result according to the validity period corresponding to the received analysis result.

It should be noted that, in this application, when setting the second duration, it can be determined based on experience, or different values can be set according to different scenarios. If you want to reduce the time spent waiting for other servers to send the resolution results of the domain name, you can set the preset second duration to be shorter. If you want to reduce the number of frequent forwarding of the first resolution request to other servers, you can set this The preset second duration is set to be longer.

When setting the third duration, it can be determined based on experience, or it can be set to a different value according to different scenarios. If you have strict requirements on the resolution results of the domain name, you can set the preset third duration to be shorter. If you want to reduce the number of frequently forwarding second resolution requests to other servers, you can set the preset third duration Is longer.

Similarly, when setting the time interval, it can also be determined based on experience, or it can be set to different values according to different scenarios. If you want to obtain the resolution results of the domain name sent by other servers as soon as possible, you can set the time interval shorter. If you want to reduce the number of frequent forwarding of the first resolution request to other servers, you can set the time interval Is longer.

In another possible implementation, it may happen that the server receives the resolution request for a certain domain name for the first time, and the server does not cache the target resolution result corresponding to the domain name locally, in order to respond to the resolution request sent by the smart device , The server needs to forward the resolution request to other servers to obtain the resolution result of the domain name carried in the resolution request sent by other servers, send the received resolution result of the domain name, and cache the domain name and its corresponding resolution result in local.

When the server receives the resolution result of the domain name sent by other servers, it also receives the validity period corresponding to the resolution result sent by other servers. The server caches the domain name, the resolution result of the domain name, and the validity period corresponding to the resolution result in local.

Among them, when setting the validity period, you can set validity periods of different durations according to different scenarios. If in order to strictly ensure the accuracy of the resolution result of a certain domain name sent to the smart device, the validity period of the domain name can be set shorter, so that the server can frequently update the target resolution result corresponding to a certain domain name in the local cache. ; If you want to effectively reduce the frequency of the server forwarding analysis requests to other servers, reduce the load when other servers process analysis requests, improve service performance, and process more resolution requests, you can set the domain name's validity period longer.

Similarly, it is determined that the resolution result of the domain name sent by other servers is not received within the preset first time period. When the server sends the target resolution result, it will also send the pre-configured time period to the receiving device (including smart devices and subordinates). Server), that is, the pre-configured time period is sent to the receiving device as the validity period corresponding to the target resolution result, so that the receiving device can perform the locally cached resolution result of the domain name according to the target resolution result and the pre-configured time period. The validity period corresponding to the analysis result is updated.

It should be noted that the method for setting the pre-configured time period is the same as the method for setting the validity period described above, and the repetition will not be repeated.

In addition, if it is determined that the target resolution result corresponding to the domain name is cached locally, and the validity period corresponding to the target resolution result has not expired, the method further includes:

Send the target analysis result.

Of course, after the server determines that the target resolution result corresponding to the domain name is cached locally, and the validity period corresponding to the target resolution result has not expired, the server can directly send the target resolution result without requesting the domain name carried in the resolution request from other servers. The analysis result of the local cache is updated according to the received analysis result.

Figure 3 is a schematic diagram of an existing data processing flow, which includes:

S301: Receive a first resolution request, and obtain domain name information carried in the first resolution request.

S302: Determine whether the target resolution result corresponding to the domain name is cached locally, if yes, execute S303, otherwise, execute S304.

S305: Determine whether a successful response message sent by another server is received, if yes, execute S306, otherwise, execute S307.

S306: Send the resolution result of the domain name carried in the success response information and cache the success response information.

Wherein, if the target resolution result corresponding to the domain name is cached locally, the target resolution result is updated according to the resolution result of the domain name carried in the successful response message, and the target resolution result is updated according to the resolution result carried in the successful response message. The validity period is to update the validity period corresponding to the target resolution result; if the target resolution result corresponding to the domain name is not cached locally, the resolution result of the domain name carried in the successful response message and the validity period corresponding to the resolution result are directly stored.

S307: Continue to wait until a successful response message sent by another server is received, and then execute S306.
