Detailed Description

It should be noted that, the user information (including but not limited to user equipment information, user personal information, etc.) and the data (including but not limited to data for analysis, stored data, presented data, etc.) related to the present application are information and data authorized by the user or fully authorized by each party, and the collection, use and processing of the related data need to comply with related laws and regulations and standards, and provide corresponding operation entries for the user to select authorization or rejection.

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Fig. 1 is a schematic diagram of an application scenario provided in an exemplary embodiment of the present application. As shown in fig. 1, includes a first device, a second device, and a computing device.

The first device may be a domain name management server and the second device may be a DNS resolution server. The first device may include domain name data. For example, the first device may include domain name data 1, domain name data 2, and domain name data 3 therein.

The first device may synchronize domain name data with the second device such that the domain name data is stored in the second device. For example, the second device may include domain name data 1, domain name data 2, and domain name data 3 therein.

The computing device may obtain a first set of domain name data from the first device, obtain a second set of domain name data from the second device, and determine a synchronization detection result based on the first set of domain name data and the second set of domain name data. For example, if the first domain name data set includes domain name data 1, domain name data 2 and domain name data 3, and the second domain name data set includes domain name data 1, domain name data 2 and domain name data 3, since the first domain name data set and the second domain name data set are the same, it may be determined that the synchronization detection result is normal. If the first domain name data set and the second domain name data set are different, the domain name data sets can be acquired from the first device and the second device for multiple times to determine a synchronous detection result.

In an embodiment of the application, the computing device may obtain a first set of domain name data in the first device and a second set of domain name data in the second device. If the first domain name data set and the second domain name data set are different, the third domain name data set in the first device and the fourth domain name data set in the second device can be obtained again after the preset time period, and the synchronous detection result can be determined according to the first domain name data set, the second domain name data set, the third domain name data set and the fourth domain name data set. Because the domain name data sets can be acquired for multiple times and can be compared for multiple times to determine the synchronous detection result, compared with the method that the synchronous detection result is determined by comparing the domain name data in the first equipment with the domain name data in the second equipment only once, the accuracy of determining the synchronous detection result is improved.

The technical scheme shown in the application is described in detail by specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and for the same or similar content, the description will not be repeated in different embodiments.

Fig. 2 is a flowchart of a domain name data synchronization detection method according to an exemplary embodiment of the present application. Referring to fig. 2, the method may include:

s201, acquiring a first domain name data set in a first device, and acquiring a second domain name data set in a second device.

The execution subject of the embodiment of the application can be a computing device or a domain name data synchronous detection device arranged in the computing device. The domain name data synchronous detection device can be realized by software or a combination of software and hardware. The domain name data synchronization detecting means may be a processor in the computing device. For ease of understanding, the execution subject will be described below as an example of a computing device.

Alternatively, the first device may be a domain name management server and the second device may be a DNS resolution server.

Alternatively, there may be a plurality of second devices. The first device may synchronize domain name data to a plurality of second devices. For example, the first device may be a domain name management server, and the plurality of second devices may be DNS resolution server 1, DNS resolution servers 2, … …, and DNS resolution server 10, respectively, and the domain name management server may synchronize domain name data with DNS resolution server 1, DNS resolution servers 2, … …, and DNS resolution server 10, respectively.

The first domain name data set and the second domain name data set may each include a plurality of pieces of domain name data, and the domain name data may include a domain name and a network address corresponding to the domain name. For example, the first set of domain name data may include domain name 1 and corresponding network address 1, domain name 2 and corresponding network address 2 and network addresses 3, … …, domain name n and corresponding network address m (n, m being an integer greater than or equal to 1).

The domain name data included in the first set of domain name data may be a full amount of domain name data in the first device and the domain name data included in the second set of domain name data may be a full amount of domain name data in the second device.

It should be noted that, since there are a plurality of second devices, for each domain name data synchronization detection, the full-size domain name data of one of the second devices may be acquired, and the full-size domain name data of all the second devices need not be acquired.

Optionally, the computing device may determine a first data pull period. The first data pull period may be a duration between a pull start time and a pull end time. For example, the first data pull period may be between 15:10 and 15:15 for 5 minutes (min).

The computing device may obtain a first set of domain name data in the first device and a second set of domain name data in the second device during a first data pull period.

For example, the first data pulling period may be 5 min between 15:10 and 15:15, and the computing device may send a data request to the first device at a pulling start time 15:10, requesting to obtain domain name data until a pulling end time 15:15, and obtaining a first domain name data set including a plurality of domain name data; and sending a data request to the second device at the pulling start time 15:10, requesting to acquire domain name data until the pulling end time 15:15, and acquiring a second domain name data set comprising a plurality of domain name data.

S202, judging whether the first domain name data set and the second domain name data set are identical.

If yes, executing S203; if not, S204 is performed.

For example, if the first domain name data set includes a domain name 1 and a corresponding network address 1, a domain name 2 and a corresponding network address 2, a domain name 3 and a corresponding network address 3, and if the second domain name data set includes a domain name 1 and a corresponding network address 1, a domain name 2 and a corresponding network address 2, a domain name 3 and a corresponding network address 3, it may be determined that the first domain name data set and the second domain name data set are the same, and S203 may be executed; if the second set of domain name data includes the domain name 1 and the corresponding network address 1, the domain name 2 and the corresponding network address 2, it may be determined that the first set of domain name data and the second set of domain name data are not identical, and S204 may be performed.

S203, determining that the synchronization detection result of the first device and the second device is synchronous normal.

If the first domain name data set is the same as the second domain name data set, the total amount of domain name data in the first device and the second device is the same, and the first device has synchronized the total amount of domain name data with the second device, then it can be determined that the synchronization detection result of the first device and the second device is normal.

For example, if the first device is a domain name management server and the second device is a DNS resolution server 1, if the first domain name data set acquired in the domain name management server is the same as the second domain name data set acquired in the DNS resolution server 1, it is indicated that the synchronization detection result of the domain name management server and the DNS resolution server 1 is normal.

S204, after the preset time length, acquiring a third domain name data set in the first equipment and a fourth domain name data set in the second equipment, and determining a synchronous detection result according to the first domain name data set, the second domain name data set, the third domain name data set and the fourth domain name data set.

The preset duration may be manually preset. For example, the preset time period may be 10 minutes.

For example, assuming that the preset duration is 10min and the first data pulling period is 15:10-15:15, in the first data pulling period 15:10-15:15, the computing device may acquire a full amount of domain name data in the first device to obtain a first domain name data set, and may acquire a full amount of domain name data in the second device to obtain a second domain name data set; after the preset duration is 10min, the second data pulling period may be 15:25-15:30, the computing device may acquire the full-scale domain name data in the first device again to obtain the third domain name data set, and may acquire the full-scale domain name data in the second device again to obtain the fourth domain name data set.

In an alternative embodiment, the synchronization detection result may be determined according to the first domain name data set, the second domain name data set, the third domain name data set, and the fourth domain name data set by: determining first difference information according to the first domain name data set and the second domain name data set; determining second difference information according to the third domain name data set and the fourth domain name data set; and determining a synchronous detection result according to the first difference information and the second difference information.

Optionally, the computing device may determine the first difference information from the first set of domain name data and the second set of domain name data.

The first difference information may include domain name data that exists in the first domain name data set and does not exist in the second domain name data set, and domain name data that exists in the second domain name data set and does not exist in the first domain name data set, that is, the first difference information may include data that the first device cannot synchronize with the second device, and error data.

For example, if the first set of domain names and the second set of domain names are as shown in table 1:

TABLE 1

Then there is no presence in the first set of domain name data and no presence in the second set of domain name data due to domain name 3 and corresponding network address 3, and domain name 4 and corresponding network address 4; the network address 5 corresponding to the domain name 3 exists in the second domain name data set, and does not exist in the first domain name data set, and the first difference information may be determined to include: domain name 3 and corresponding network address 3, domain name 4 corresponding network address 4, and domain name 3 and corresponding network address 5, as shown in table 2:

TABLE 2

The network address corresponding to the domain name 3 may be the network address 3, but when the first device synchronizes the domain name 3 and the corresponding network address 3 to the second device, an error occurs, so that the first domain name data set includes the domain name 3 and the corresponding network address 3, and the second domain name data set includes the domain name 3 and the corresponding network address 5; the domain name 4 and the corresponding network address 4 may be domain name data that the first device has not synchronized to the second device, resulting in the first set of domain name data including the domain name 4 and the corresponding network address 4 and the second set of domain name data not including the domain name 4 and the corresponding network address 4.

Optionally, the computing device may determine the second difference information from the third set of domain name data and the fourth set of domain name data.

The second difference information may include domain name data that exists in the third domain name data set and does not exist in the fourth domain name data set, and domain name data that exists in the fourth domain name data set and does not exist in the third domain name data set.

For example, if the third set of domain names and the fourth set of domain names are as shown in table 3:

TABLE 3 Table 3

Then, as domain name 3 and corresponding network address 3 are present in the first set of domain name data, they are not present in the second set of domain name data; the network address 5 corresponding to the domain name 3 exists in the second domain name data set, and does not exist in the first domain name data set, and the second difference information may be determined to include: domain name 3 and corresponding network address 3, and domain name 3 and corresponding network address 5, as shown in table 4:

TABLE 4 Table 4

Alternatively, the computing device may determine the synchronization detection result from the first difference information and the second difference information.

For example, if the first difference information is shown in table 2, and the second difference information is shown in table 4, since the domain name 3 and the corresponding network address 3 and the domain name 3 and the corresponding network address 5 appear in the first difference information and appear again in the second difference information, it is determined that the synchronization detection result is abnormal synchronization, which means that the domain name 3 and the corresponding network address 3 and the domain name 3 and the corresponding network address 5 are indeed inconsistent data in the first device and the second device.

In the embodiment of the application, the computing device can acquire the first domain name data set in the first device and acquire the second domain name data set in the second device, and judge whether the first domain name data set and the second domain name data set are identical. If the first domain name data set and the second domain name data set are the same, determining that the synchronization detection result of the first equipment and the second equipment is synchronous; if the first domain name data set and the second domain name data set are different, the computing device may acquire a third domain name data set in the first device and a fourth domain name data set in the second device after the preset duration, and determine a synchronization detection result according to the first domain name data set, the second domain name data set, the third domain name data set and the fourth domain name data set. Because the domain name data sets can be acquired for multiple times and can be compared for multiple times to determine the synchronous detection result, compared with the method that the synchronous detection result is determined by comparing the domain name data in the first equipment with the domain name data in the second equipment only once, the accuracy of determining the synchronous detection result is improved.

Next, the above-described domain name data synchronization detection method will be described in detail with reference to fig. 3, based on the embodiment shown in fig. 2.

Fig. 3 is a flowchart of another domain name data synchronization detection method according to an exemplary embodiment of the present application. Referring to fig. 3, the method may include:

s301, determining a first data pulling period.

Alternatively, the computing device may periodically determine the first data pull period.

For example, the computing device may determine that the first data pull period is between 15:10-15:15 for 5 minutes.

S302, in a first data pulling period, a first domain name data set is acquired in a first device.

In an alternative embodiment, the first domain name data set may be acquired in the first device during the first data pull period by: requesting to obtain a plurality of first domain name data fragments from the first device in a first data pulling period; the first set of domain name data is determined to include domain name data in a plurality of first domain name data fragments.

The first domain name data fragment may be part of the domain name data of the full amount of domain name data in the first device. The first domain name data fragment may include a plurality of pieces of domain name data therein. For example, if 2 ten thousand pieces of domain name data are included in the first device, the first domain name data fragment may be 2000 pieces of domain name data therein.

Alternatively, the first device may be requested to obtain a plurality of first domain name data fragments by: generating a plurality of data acquisition tasks; transmitting a data acquisition task to a plurality of auxiliary devices; and receiving a plurality of first domain name data fragments sent by a plurality of auxiliary devices.

Since the data size of the full-size domain name data in the first device may be large, the computing device cannot acquire the full-size domain name data in the first device at a time, and the computing device may acquire the domain name data fragments in the first device multiple times through multiple auxiliary devices, so as to acquire the full-size domain name data in the first device.

The auxiliary device may be used to obtain domain name data fragments in the first device or the second device. Alternatively, there may be a plurality of auxiliary devices.

The data acquisition task may be used to instruct the auxiliary device to acquire the corresponding domain name data fragment in the first device during the first data pull period.

Optionally, the data acquisition task may include a first data pull period and a domain name data fragment identifier.

The domain name data fragment identification may be used to indicate the amount of data for the domain name data fragment. For example, if the domain name data fragment identifier is 2000, it may be used to instruct that 2000 pieces of domain name data be acquired in the first device.

For example, the first data pull period 15:10-15:15 and domain name data fragment identifier 2000 may be included in the data acquisition task.

Optionally, during the first data pull period, the computing device may generate a plurality of data acquisition tasks and send the data acquisition tasks to the plurality of auxiliary devices, respectively, so that the auxiliary devices may perform the data acquisition tasks.

For example, if there are 10 auxiliary devices, during the first data pull period, the computing device may generate a data acquisition task and send the data acquisition task to the 10 auxiliary devices, respectively. The first data pull period 15:10-15:15 and domain name data fragment identifier 2000 may be included in the data acquisition task.

Optionally, for any auxiliary device, after the auxiliary device receives the data acquisition task, the auxiliary device may send a data acquisition request to the first device. The data acquisition request may include a first data pull period and a domain name data fragment identifier. For example, the auxiliary device 1 may send a data acquisition request 1 to the first device, where the data acquisition request 1 may include a first data pull period 15:10-15:15 and a domain name data fragment identifier 2000.

After receiving the data acquisition request sent by the auxiliary device, the first device may send the first domain name data fragment to the auxiliary device according to the data acquisition request. After receiving the first domain name data fragment, the auxiliary device may send the first domain name data fragment to the computing device.

For example, if the first device includes 2 ten thousand pieces of domain name data, the first device receives the data acquisition request 1 sent by the auxiliary device 1, and the data acquisition request 1 includes the first data pulling period 15:10-15:15 and the domain name data slicing identifier 2000, the first device may determine the first domain name data slicing 1 in the 2 ten thousand pieces of domain name data according to the domain name data slicing identifier 2000, and send the first domain name data slicing 1 to the auxiliary device 1. The first domain name data fragment 1 may include 2000 pieces of domain name data that are first generated from the 2 ten thousand pieces of domain name data. After the auxiliary device 1 receives the first domain name data fragment 1, the first domain name data fragment 1 may be sent to the computing device.

The computing device may receive a first domain name data fragment sent by the plurality of auxiliary devices to obtain a full amount of domain name data in the first device, thereby obtaining a first set of domain name data. The first set of domain name data may include domain name data in a plurality of first domain name data fragments.

It should be noted that, the first device may receive data acquisition requests sent by a plurality of auxiliary devices. The first device can send different first domain name data fragments to the auxiliary device according to the time sequence of receiving the data acquisition request and according to the generation time of the domain name data, so that the auxiliary device is prevented from repeatedly acquiring the domain name data.

For example, if the first device includes 2 ten thousand pieces of domain name data, if there are 10 auxiliary devices, if the first device receives the data acquisition request 1 sent by the auxiliary device 1 at 15:10:09, the first device may send 2000 pieces of domain name data with early generation time to the auxiliary device 1; the first device receives the data acquisition request 2 sent by the auxiliary device 2 at 15:10:12, and the first device can send another 2000 pieces of domain name data to the auxiliary device 2; … …; the first device receives the data acquisition request 10 sent by the auxiliary device 10 at 15:14:50, and the first device may send 2000 pieces of domain name data with the latest generation time to the auxiliary device 10.

S303, acquiring a second domain name data set in the second device in the first data pulling period.

It should be noted that, the executing process of acquiring the second domain name data set in the second device may refer to the executing process of acquiring the first domain name data set in the first device, which is not described herein.

S304, judging whether the first domain name data set and the second domain name data set are identical.

If yes, executing S305; if not, S306 is performed.

For example, if the first domain name data set includes a domain name 1 and a corresponding network address 1, a domain name 2 and a corresponding network address 2, a domain name 3 and a corresponding network address 3, and if the second domain name data set includes a domain name 1 and a corresponding network address 1, a domain name 2 and a corresponding network address 2, a domain name 3 and a corresponding network address 3, it may be determined that the first domain name data set and the second domain name data set are the same, and S305 may be executed; if the second set of domain name data includes the domain name 1 and the corresponding network address 1, the domain name 2 and the corresponding network address 2, it may be determined that the first set of domain name data and the second set of domain name data are not identical, and S306 may be performed.

S305, determining that the synchronous detection result is synchronous normal.

It should be noted that, the execution process of step S305 may refer to step S203, and will not be described herein.

S306, after the preset duration, acquiring a third domain name data set in the first device and acquiring a fourth domain name data set in the second device.

Alternatively, the computing device may determine a second data pull period after the preset duration, and during the second data pull period, obtain a third set of domain name data in the first device, and a fourth set of domain name data in the second device.

For example, if the preset duration is 10min and the first data pulling period is 15:10-15:15, the second data pulling period may be 15:25-15:30, the computing device may obtain the full amount of domain name data in the first device during the second data pulling period 15:25-15:30, so as to obtain the third domain name data set, and may obtain the full amount of domain name data in the second device, so as to obtain the fourth domain name data set.

It should be noted that, the specific execution process of acquiring the third domain name data set and the fourth domain name data set may refer to the specific execution process of acquiring the first domain name data set in step S302, which is not described herein.

S307, determining the first difference information according to the first domain name data set and the second domain name data set.

Optionally, the computing device may process the first domain name data set and the second domain name data set through a preset programming model to obtain the first difference information.

Alternatively, a programming model may be pre-installed in the computing device. The programming model may be a big data parallel computing model that may be used to determine the difference information.

For example, if the first set of domain name data and the second set of domain name data are as shown in table 1, the computing device may compare the domain name data in the first set of domain name data and the second set of domain name data through a preset programming model to obtain the first difference information, as shown in table 2.

And S308, determining second difference information according to the third domain name data set and the fourth domain name data set.

Optionally, the computing device may process the third domain name data set and the fourth domain name data set through a programming model to obtain the second difference information.

For example, if the third set of domain name data and the fourth set of domain name data are as shown in table 3, the computing device may compare the domain name data in the third set of domain name data and the fourth set of domain name data through a preset programming model to obtain the second difference information, as shown in table 4.

S309, determining whether the second difference information is null.

If yes, S305 is executed, and if no, S310 is executed.

The second difference information being empty means that the second difference information does not exist.

If the second difference information is null, it indicates that the domain name data in the third domain name data set and the fourth domain name data set are the same, that is, the domain name data in the first device and the domain name data in the second device are consistent, S305 may be executed, that is, it is determined that the synchronization detection result is normal.

If the second difference information is not null, that is, if there is the second difference information, since neither the first difference information nor the second difference information is null, S310 may be performed.

It should be noted that, the first difference information is not null, and the second difference information is null, because the first device may not have access to synchronize part of the domain name data in the first domain name data set to the second device when acquiring the first domain name data set and the second domain name data set, so the first difference information is not null. After the preset duration, when the third domain name data set and the fourth domain name data set are acquired, the first device may have synchronized all domain name data in the first domain name data set to the second device, so that the acquired third domain name data set and fourth domain name data set are the same, and therefore the second difference information is null.

S310, determining whether domain name data in an intersection domain name data set of the first difference information and the second difference information is zero.

The first difference information and the second difference information may include intersection domain name data sets, respectively. The intersection domain name data set may include a plurality of pieces of domain name data.

Optionally, the computing device may determine an intersection domain name data set of the first difference information and the second difference information.

For example, if the first difference information is shown in table 2 and the second difference information is shown in table 4, it may be determined that the intersection domain name data set of the first difference information and the second difference information includes: domain name 3 and corresponding network address 3, and domain name 3 and corresponding network address 5.

If the domain name data in the intersection domain name data set is zero, that is, there is no intersection domain name data set, which indicates that the first difference information determined due to the inconsistent domain name data in the first domain name data set and the second domain name data set is not present in the second difference information, which indicates that the first difference information has been synchronized by the first device with the second device after the preset duration, step S305 may be executed, that is, it is determined that the synchronization detection result is normal synchronization.

For example, if the first set of domain name data and the second set of domain name data are as shown in table 5, it may be determined that the first difference information includes domain name 4 and corresponding network address 4; if the third set of domain name data and the fourth set of domain name data are as shown in table 6, it may be determined that the domain name 5 and the corresponding network address 5 are included in the second difference information. If there is no intersection domain name data set between the first difference information and the second difference information, i.e., the number of domain name data in the intersection domain name data set is zero, which indicates that the first device has synchronized the domain name 4 and the network address 4 with the second device (as shown in table 6), step S305 may be performed, i.e., it is determined that the synchronization detection result for the first domain name data set and the second domain name data set acquired in the first data pull period is normal synchronization.

TABLE 5

TABLE 6

S311, determining that the synchronous detection result is abnormal.

The number of the domain name data in the intersection domain name data set is greater than zero, that is, the intersection domain name data set exists, which means that because the domain name data in the first difference information reappears in the second difference information, it is indicated that after a preset duration, the first device does not synchronize the domain name data in the first difference information with the second device, or the synchronization fails, or the synchronization is wrong, and if only the domain name data sets are acquired twice, that is, the first domain name data set and the second domain name data set are acquired, and the third domain name data set and the fourth domain name data set are acquired for the second time, it is determined that the synchronization detection result is abnormal.

For example, if the first difference information is shown in table 2 and the second difference information is shown in table 4, since the first device has synchronized domain name 4 and corresponding network address 4 to the second device, there is no domain name 4 and corresponding network address 4 in the second difference information; the first device should synchronize the domain name 3 and the corresponding network address 3 with the second device, and an error occurs in the synchronization process, so that the second device obtains the domain name 3 and the corresponding network address 5, and therefore the domain name 3 and the corresponding network address 3, and the domain name 3 and the corresponding network address 5 still exist in the second difference information. It may be determined that there is an intersection domain name data set between the first difference information and the second difference information. The intersection domain name data set includes a domain name 3 and a corresponding network address 3, and a domain name 3 and a corresponding network address 5, that is, the number of domain name data in the intersection domain name data set is greater than zero, so that it can be determined that the synchronization detection result for the first domain name data set and the second domain name data set acquired in the first data pulling period is abnormal synchronization.

Optionally, because the domain name data in the first device and the second device are changed in real time, in order to further improve accuracy of determining the synchronization detection result, if the number of domain name data in the intersection domain name data set is greater than zero, the computing device may repeatedly execute the preset step until it is determined that the synchronization detection result is normal, or when the repeatedly executed preset step satisfies the preset condition, it is determined that the synchronization detection result is abnormal.

The presetting step may include: after the preset duration, a third domain name data set is acquired in the first equipment, a fourth domain name data set is acquired in the second equipment, and a synchronous detection result is determined according to the first domain name data set, the second domain name data set, the third domain name data set and the fourth domain name data set.

The preset conditions include at least one of the following: the execution times of the preset steps are larger than or equal to the preset times; the same domain name data exists in the intersection domain name data set obtained N times in succession. Wherein N is an integer greater than or equal to 1, N is less than the preset times, and the intersection domain name data set obtained by continuously performing N preset steps is the intersection domain name data set obtained by continuously performing N preset steps.

Optionally, after repeatedly performing the preset step, determining the synchronous detection result may include 3 cases as follows:

case 1: and determining that the synchronous detection result is synchronous normal.

For example, if the computing device obtains a first set of domain name data in the first device during the first data pull period, the first set of domain name data may include domain name data 1, domain name data 2, … …, and domain name data 5000. A second set of domain name data is obtained in the second device, the second set of domain name data comprising domain name data 1, domain name data 2, … …, domain name data 2000. The first difference information includes domain name data 2001, … … and domain name data 5000.

In a second data pulling period after the preset duration, the computing device acquires a third domain name data set 1 in the first device, wherein the third domain name data set 1 comprises domain name data 1, domain name data 2, … … and domain name data 5000, acquires a fourth domain name data set 1 in the second device, wherein the fourth domain name data set 1 comprises domain name data 1, domain name data 2, … … and domain name data 3000, and the second difference information 1 comprises domain name data 3001, … … and domain name data 5000. It may be determined that the intersection domain name data set 1 includes the domain name data 3001, … …, the domain name data 5000 according to the first difference information and the second difference information 1. The domain name data in the intersection domain name data set 1 may be data that is not synchronized.

Because the first device always synchronizes the domain name data to the second device in real time, in order to improve the accuracy of determining the synchronization detection result, the computing device may repeatedly perform the preset steps, that is, acquire a third domain name data set 2 again in the first device, where the third domain name data set 2 includes domain name data 1, domain name data 2, … …, and domain name data 5000, and acquire a fourth domain name data set 2 in the second device, where the fourth domain name data set 2 includes domain name data 1, domain name data 2, … …, and domain name data 5000; the second difference information 2 does not exist, and the synchronous detection result is that the synchronization is normal, and the domain name data synchronous detection can be ended.

Case 2: the execution times of the preset steps are larger than or equal to the preset times, and the synchronous detection result is determined to be abnormal.

The preset number of times may be manually preset. For example, the preset number of times may be 5 times.

For example, if the preset number of times is 5, if the computing device has performed 5 preset steps, the first device has enough time to synchronize domain name data with the second device, but still has an intersection domain name data set, which indicates that the domain name data in the intersection domain name data set is really inconsistent data in the first device and the second device, it may be determined that the synchronization detection result is abnormal, and the domain name data synchronization detection is ended.

Case 3: the same domain name data exists in the intersection domain name data set obtained continuously N times, and the synchronous detection result is determined to be abnormal.

N is smaller than the preset times, and the intersection domain name data set obtained by continuously carrying out the preset steps for N times is the intersection domain name data set obtained by continuously carrying out the preset steps for N times.

For example, if the preset number of times is 5 times, N may be 3 times.

For example, if the computing device determines that the intersection domain name data set 1 includes domain name data 1, domain name data 2, and domain name data 3 according to the first difference information and the second difference information 1 for the 1 st time; determining that the intersection domain name data set 2 comprises domain name data 2 and domain name data 3 according to the first difference information and the second difference information 2 at the 2 nd time; according to the first difference information and the second difference information 3, the intersection domain name data set 3 comprises domain name data 2 and domain name data 3, the domain name data 2 and the domain name data 3 exist in the intersection domain name data set for 3 continuous times, the domain name data 2 and the domain name data 3 can be determined to be inconsistent data in the first equipment and the second equipment, and the synchronous detection result can be determined to be abnormal.

Optionally, if the synchronization detection result is abnormal synchronization, the domain name data in the first device and the second device may be subjected to data correction according to the domain name data in the intersection domain name data set, so that the domain name data in the first device and the domain name data in the second device are kept consistent.

For example, if the intersection domain name data includes domain name data 1, the domain name data 1 exists in the first device but not in the second device, the domain name data 1 may be sent to the second device by the first device, so that the second device obtains the domain name data 1; if domain name data 2 exists in the second device but not in the first device, domain name data 2 may be deleted in the second device.

In the embodiment of the application, the computing device can determine a first data pulling period, acquire a first domain name data set in the first device and acquire a second domain name data set in the second device in the first data pulling period. The computing device may determine whether the first set of domain name data and the second set of domain name data are the same. If the synchronization detection results are the same, the synchronization detection results can be determined to be normal; if the first domain name data set and the second domain name data set are different, the third domain name data set and the fourth domain name data set can be acquired in the first device after the preset time period. The computing device may determine first difference information from the first set of domain name data and the second set of domain name data, and determine second difference information from the third set of domain name data and the fourth set of domain name data. The computing device may determine whether the second difference information is empty. If yes, the synchronous detection result can be determined to be synchronous normal; if not, it may be determined whether the domain name data in the intersection domain name data set of the first difference information and the second difference information is zero. If the domain name data in the intersection domain name data set is zero, determining that the synchronous detection result is abnormal; if the domain name data in the intersection domain name data set is not zero, the synchronization detection result can be determined to be abnormal. Since the computing device may determine the first difference information from the first set of domain name data and the second set of domain name data; and after the preset duration, acquiring the third domain name data set and the fourth domain name data set again, and determining the second difference information, so that the synchronous detection result can be determined according to the intersection domain name set of the first difference information and the second difference information.

Next, on the basis of any of the above embodiments, by way of a specific example, a case of acquiring the domain name data set twice will be described in further detail with reference to fig. 4A; the case of acquiring multiple sets of domain name data is described in further detail in connection with fig. 4B.

Fig. 4A is a schematic diagram illustrating a process of domain name data synchronization detection according to an exemplary embodiment of the present application. Referring to fig. 4A, steps (1) (2) (3) are included.

During the first data pull period, the computing device may obtain a first set of domain name data in the first device, where the first set of domain name data may include domain name 1 and corresponding network address 1, domain name 2 and corresponding network address 2, domain name 3 and corresponding network address 3, and domain name 4 and corresponding network address 4.

The computing device may obtain a second set of domain name data in the second device, which may include domain name 1 and corresponding network address 1, domain name 2 and corresponding network address 2, domain name 3 and corresponding network address 5.

In step (1), the computing device may determine first difference information from the first set of domain name data and the second set of domain name data. Since domain name 3 and corresponding network address 3, and domain name 4 and corresponding network address 4 are present in the first set of domain name data, the second set of domain name data is absent; the domain name 3 and the corresponding network address 5 are present in the second domain name data set, and the first domain name data set is absent, it may be determined that the first difference information includes the domain name 3 and the corresponding network address 3, and the domain name 4 and the corresponding network address 4, and the domain name 3 and the corresponding network address 5.

Because the first difference information exists, it is indicated that the first domain name data set and the second domain name data set are different, that is, the domain name data in the first device and the domain name data in the second device are inconsistent, possibly because the first device has not yet reached to synchronize part of the domain name data with the second device, or the domain name data is inconsistent due to synchronization errors, etc., after the preset duration, the computing device may acquire the third domain name data set in the first device and the fourth domain name data set in the second device in the second data pull period.

If the domain name data in the first device is not updated within the preset duration, the third domain name data set still includes the domain name 1 and the corresponding network address 1, the domain name 2 and the corresponding network address 2, the domain name 3 and the corresponding network address 3, and the domain name 4 and the corresponding network address 4.

Because the first device synchronizes domain name data to the second device in real time, the first device may domain name 4 and corresponding network address 4 to the second device within a preset duration, and the fourth set of domain name data acquired by the computing device may include domain name 1 and corresponding network address 1, domain name 2 and corresponding network address 2, domain name 3 and corresponding network address 5, domain name 4 and corresponding network address 4.

In step (2), the computing device may determine second difference information from the third set of domain name data and the fourth set of domain name data. Because of the presence of domain name 3 and corresponding network address 3 in the third set of domain name data, the fourth set of domain name data does not; the fourth set of domain name data has domain name 3 and corresponding network address 5, and the third set of domain name data does not have domain name 3 and corresponding network address 3, and domain name 3 and corresponding network address 5 may be determined to be included in the second difference information.

Since the second difference information is not null, in step (3), an intersection domain name data set may be determined according to the first difference information and the second difference information. The intersection domain name data set may include a domain name 3 and a corresponding network address 3, and a domain name 3 and a corresponding network address 5. Because the intersection domain name data set is determined according to the first difference information and the second difference information after the preset time period, the first device may have completed synchronizing the domain name data which needs to be synchronized to the second device within the preset time period, so that the intersection domain name data set excludes the domain name data which is not synchronized yet, the domain name data of the intersection domain name data set appears in the first difference information and appears again in the second difference information, the domain name data in the intersection domain name data set can be determined to be the domain name data with wrong synchronization, the synchronization detection result can be determined to be abnormal synchronization, and the domain name data synchronization detection is ended.

In the embodiment of the application, the computing device can acquire a first domain name data set in the first device and acquire a second domain name data set in the second device in the first data pull period. If the first domain name data set is inconsistent with the second domain name data set, that is, the first difference information exists, the third domain name data set can be obtained in the first device after the preset duration, the fourth domain name data set can be obtained in the second device, and the second difference information is determined. The computing device may determine an intersection domain name data set from the first difference information and the second difference information. If the number of the domain name data in the intersection domain name data set is zero, the synchronization result can be determined to be normal; if the number of domain name data in the intersection domain name data set is greater than zero, the synchronization result can be determined to be abnormal. Because the computing device can determine the first difference information and the second difference information and can determine the synchronous detection result according to the intersection domain name set of the first difference information and the second difference information, compared with the method that only one comparison is performed on the domain name data in the first device and the domain name data in the second device to determine the synchronous detection result, the accuracy of determining the synchronous detection result is improved.

Fig. 4B is a schematic diagram of a process of domain name data synchronization detection according to an exemplary embodiment of the present application. Referring to fig. 4B, steps (1) (2) (3) (4) (5) (6) (7) are included.

During the first data pull period, the computing device may obtain a first set of domain name data in the first device, the domain name data included in the first set of domain name data may be as shown in fig. 4B.

The computing device may obtain a second set of domain name data in the second device, the domain name data included in the second set of domain name data may be as shown in fig. 4B.

In step (1), the computing device may determine first difference information from the first set of domain name data and the second set of domain name data. Since domain name 3 and corresponding network address 3, domain name 4 and corresponding network address 4, and domain name 5 and corresponding network address 5 are present in the first set of domain name data, the second set of domain name data is absent; the second set of domain name data has domain name 3 and corresponding network address s, and the first set of domain name data does not have domain name 3 and corresponding network address 3, and domain name 4 and corresponding network address 4, domain name 5 and corresponding network address 5, and domain name 3 and corresponding network address s may be determined to be included in the first difference information.

Because the first difference information exists, it is indicated that the first domain name data set and the second domain name data set are different, that is, the domain name data in the first device and the domain name data in the second device are inconsistent, possibly because the first device has not yet reached to synchronize part of the domain name data with the second device, or the domain name data is inconsistent due to synchronization errors, etc., after the preset duration 1, the computing device may acquire the third domain name data set 1 in the first device and acquire the fourth domain name data set 1 in the second device in the second data pull period 1.

If the domain name 6 and the corresponding network address 6 are newly added in the first device within the preset duration 1, the domain name data included in the third domain name data set 1 may be as shown in fig. 4B.

Since the first device synchronizes domain name data to the second device in real time, the first device may synchronize domain name 4 and corresponding network address 4 to the second device within the preset duration 1, and the domain name data included in the fourth domain name data set 1 acquired by the computing device may be as shown in fig. 4B.

In step (2), the computing device may determine second difference information 1 from the third set of domain name data 1 and the fourth set of domain name data 1. Since domain name 3 and corresponding network address 3, domain name 5 and corresponding network address 5, and domain name 6 and corresponding network address 6 are present in the third domain name data set 1, the fourth domain name data set 1 is absent; the presence of domain name 3 and corresponding network address s in the fourth set of domain name data 1, while the absence of the third set of domain name data 1, may determine that the second difference information 1 includes domain name 3 and corresponding network address 3, domain name 5 and corresponding network address 5, domain name 6 and corresponding network address 6, and domain name 3 and corresponding network address s.

Since the second difference information 1 is not empty, in step (3), the intersection domain name data set 1 may be determined according to the first difference information and the second difference information 1. Included in intersection domain name data set 1 may be domain name 3 and corresponding network address 3, domain name 5 and corresponding network address 5, and domain name 3 and corresponding network address 5. Because the number of the domain name data in the intersection domain name data set 1 is greater than zero, the intersection domain name data set 1 is determined according to the first difference information and the second difference information after the preset time period 1, and the intersection domain name data set 1 may have data which are not synchronized in time or data which are failed to be synchronized, so that the preset step can be repeatedly executed, and then after the preset time period 2, the computing device can acquire the third domain name data set 2 in the first device in the second data pulling period 2. If the domain name data in the first device is not updated within the preset duration 2, the third domain name data set 2 may be as shown in fig. 4B; the first device synchronizes the domain name 5 and the corresponding network address 5 to the second device within the preset duration 2, and the fourth domain name data set 2 acquired in the second device may be as shown in fig. 4B.

In step (4), the computing device may determine second difference information 2 from the third set of domain name data 2 and the fourth set of domain name data 2 as shown in fig. 4B. Since the second difference information 2 is not empty, in step (5), the intersection domain name data set 2 may be determined from the first difference information and the second difference information 2 as shown in fig. 4B. Since the number of domain name data in the intersection domain name data set 2 is greater than zero, after the preset duration 3, the computing device may acquire a third set of domain name data 3 in the first device during the second data pull period 3. If the domain name data in the first device is not updated within the preset duration 3, the third domain name data set 3 may be as shown in fig. 4B; if the first device synchronizes the domain name 6 and the corresponding network address 6 to the second device within the preset duration 3, the fourth domain name data set 3 acquired in the second device may be as shown in fig. 4B.

In step (6), the computing device may determine second difference information 3 from the third set of domain name data 3 and the fourth set of domain name data 3 as shown in fig. 4B. Since the second difference information 3 is not empty, in step (7), the intersection domain name data set 3 may be determined from the first difference information and the second difference information 3 as shown in fig. 4B. Since the domain name 3 and the corresponding network address 3, and the domain name 3 and the corresponding network address s have appeared 3 times in the intersection domain name data set 1, the intersection domain name data set 2, and the intersection domain name data set 3, it can be determined that the domain name 3 and the corresponding network address 3, and the domain name 3 and the corresponding network address s are indeed inconsistent data in the first device and the second device; and the intersection domain name data set 2 and the domain name data in the intersection domain name data set 3 are consistent, namely, it can be determined that inconsistent data in the first device and the second device are not changed any more, and it can also be determined that the domain name 3 and the corresponding network address 3, and the domain name 3 and the corresponding network address s are inconsistent data in the first device and the second device. The synchronization detection result can be determined to be abnormal, and the domain name data synchronization detection is ended.

In the embodiment of the application, the computing device can acquire a first domain name data set in the first device and acquire a second domain name data set in the second device in the first data pull period. If the first domain name data set is inconsistent with the second domain name data set, that is, the first difference information exists, the third domain name data set can be obtained in the first device after the preset duration, the fourth domain name data set can be obtained in the second device, and the second difference information is determined. The computing device may determine an intersection domain name data set from the first difference information and the second difference information. If the number of the domain name data in the intersection domain name data set is zero, the synchronization result can be determined to be normal; if the number of domain name data in the intersection domain name data set is greater than zero, a preset step may be performed until it is determined that the synchronization detection result is normal for synchronization, or it is determined that the synchronization detection result is abnormal for synchronization when the number of times of performing the preset step is greater than or equal to a preset number of times. Because the computing device can determine the first difference information and the second difference information for a plurality of times, and can determine the intersection domain name set for a plurality of times according to the first difference information and the second difference information so as to determine the synchronous detection result, compared with the method that only one-time comparison is performed on the domain name data in the first device and the domain name data in the second device so as to determine the synchronous detection result, the accuracy of determining the synchronous detection result under the scene of high concurrent data change is improved.
