When some IPs are abnormal, the domain name resolution needs to be automatically switched to the normal entry IP, and the operator's DNS resolution needs to be refreshed to ensure the normal operation of the business external services. Currently, the central control end needs to automatically make decisions and execute the switching plan based on the business domain name status data reported by the monitoring probe in abnormal situations.

It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application.

The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0020] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0021] In view of the technical problems raised by the background technology, the present application provides a domain name resolution switching method, device, electronic device and storage medium, which can adapt to various business deployment architectures and improve business stability and reliability by creating a universal domain name switching model.

[0022] See the instruction manual Figure 1 , a domain name resolution switching method provided in an embodiment of the present application includes the following steps: S1. Collect monitoring data of the service domain name resolution IP through a monitoring probe, and perform noise reduction processing on the noise reduction feature bits of the monitoring data to obtain monitoring data to be analyzed; the noise reduction feature bits include cloud vendors and proxy IPs; S2, modeling the basic characteristic bits of the monitoring data to be analyzed, and calculating the first actual score and the first ideal score of each basic characteristic bit; and modeling the monitoring indicator characteristic bits of the monitoring data to be analyzed, and calculating the weighted ratio according to the set weight of each monitoring indicator characteristic bit; the basic characteristic bits include the computer room and the operator; the monitoring indicator characteristic bits include Ping detection, ping delay and interface status code; S3. If the weighted ratio is less than a set threshold, the service domain name resolution IP is switched according to the calculated first actual score and first ideal score of each basic feature bit.

[0023] Specifically, in step S1, the noise reduction feature bits are a set of features used to screen and process abnormal data that may interfere with decision-making during the domain name resolution switching decision-making process. These features are mainly derived from monitoring data, and their purpose is to reduce the noise caused by abnormal external factors and make the decision basis more accurate and reliable.

[0024] In the present application, the noise reduction feature bits include cloud vendors and proxy IPs. If all the data reported by a cloud vendor are abnormal (for example, all monitored resolution IPs are displayed as unavailable under the monitoring of this cloud vendor), this may be caused by the cloud vendor's own network, configuration or other problems, rather than a real problem with the monitored resolution IP. At this point, all data reported by this cloud vendor needs to be screened out from the original monitoring data. Similarly, for a specific proxy IP, if all the data it reports are abnormal, it is likely that the corresponding monitoring probe itself has a fault. All data reported by this proxy IP needs to be screened out from the original monitoring data.

[0025] By reducing the noise of monitoring data to obtain the monitoring data to be analyzed, it is helpful to improve the quality of domain name resolution switching decisions. If data noise reduction is not performed, these abnormal factors may frequently trigger unnecessary domain name resolution switching, or cause the switching that should be performed to be not executed in time, thus affecting the normal operation of the business.

[0026] See the instruction manual Figure 2 In step S2, the basic feature bit modeling of the monitoring data to be analyzed and the first actual score and the first ideal score of each basic feature bit are calculated, including the following steps: S201, performing binary modeling based on the computer room and the operator as basic feature bits to obtain a two-dimensional feature matrix; S202. Calculate a first ideal score and a first actual score for each basic feature bit according to the feature matrix; the first ideal score and the first actual score are used to represent the total number of times each basic feature bit appears in all business domain name resolution IPs under an ideal operating state and an actual operating state, respectively.

[0027] Specifically, in step S201, by performing binary modeling on the computer room and operator of the service domain name resolution IP, the ownership of each IP in terms of different key attributes can be presented in a clear and structured manner. Each 1 or 0 represents whether the resolution IP has the corresponding basic feature bit, which can facilitate subsequent data statistics, comparisons, and the formulation of relevant decision-making strategies based on these basic feature bits. For example, the obtained two-dimensional feature matrix is ​​shown in Table 1. For IP1, its computer room belongs to A (the corresponding value of the computer room A column is 1), and the operator belongs to X (the corresponding value of the operator X column is 1), and it does not belong to computer room B and operator Y (the value of the corresponding column is 0).

[0028]

[0029] Table 1 In step S202, under an ideal operating state, assuming that all resolved IPs are evenly distributed among various computer rooms and operators, the first ideal total score of each basic feature bit (computer room A, computer room B, operator X, operator Y) is calculated. The calculation method is to count the total number of times each basic feature bit appears in all resolved IPs. For example, if there are 4 resolved IPs in total, and computer room A appears in 2 of them, then the first ideal score of computer room A is 2. Similarly, the first actual score of each basic feature bit under the actual operating state is calculated.

[0030] By performing such binary modeling and analysis on the basic feature bits, a reference framework is provided for domain name resolution switching decisions from the perspective of the computer room and the operator, which helps to formulate corresponding strategies more scientifically and rationally. For example, if the computer room where the currently used resolution IP is located shows signs of failure and domain name resolution switching is required, priority can be given to switching to the resolution IP of the same operator but in a different computer room.

[0031] In addition, see the instructions for Figure 3 The monitoring indicator characteristic bit modeling of the monitoring data to be analyzed and the weighted ratio calculation according to the set weight of each monitoring indicator characteristic bit include the following steps: P301, converting the Ping detection, Ping delay and interface status code in the monitoring data to be analyzed into 0 / 1 status respectively through a standardized evaluation strategy; P302, according to the Ping detection, the Ping delay and the 0 / 1 state of the interface status code and the set 0 / 1 state value, the monitoring indicator characteristic bit is modeled, and the second ideal score and the second actual score of each monitoring indicator characteristic bit are obtained; the second ideal score and the second actual score are used to represent the total state value of each monitoring indicator characteristic bit in all service domain name resolution IPs under the ideal operating state and the actual operating state, respectively; P303. Calculate the ideal weighted total score and the actual weighted total score of all monitoring indicator characteristic bits according to the corresponding weights set for each monitoring indicator characteristic bit, and calculate the weighted ratio according to the ideal weighted total score and the actual weighted total score.

[0032] Specifically, in step P301, since the characteristics of different monitoring indicators are different, by converting them into standardized judgments of 0 / 1 states, the same logic and standards can be used to measure whether each indicator meets the standard, providing a unified basis for subsequent comprehensive evaluation. The ping probe is mainly used to detect whether the resolved IP is reachable. If the ping command can be successfully sent from the monitoring probe to the target resolved IP and receive a response, it is determined to be "connected" and the corresponding state is converted to 1; if no response is received within the specified time, it is determined to be "unconnected" and the state is converted to 0. The ping delay measures the time it takes for a data packet to be sent from the monitoring probe to the target resolved IP and returned. The ping delay <10ms is set to be qualified, and the corresponding state is converted to 1; if the ping delay is greater than or equal to 10ms, it is determined to be unqualified and the state is converted to 0. The interface status code is the response status identifier of the server to the request. Taking the HTTP protocol as an example, the 200 status code indicates that the request is successful. At this time, the corresponding state of the interface status code is converted to 1; while other non-200 status codes are determined to be unqualified and the corresponding state is converted to 0.

[0033] Furthermore, in order to avoid misjudgment due to short-term network fluctuations or instantaneous anomalies, an abnormal data duration determination mechanism is introduced. For the ping probe, the ping delay and the interface status code, an abnormal data duration threshold is set respectively. For example, if the ping probe is in the "unreachable" state for 3 consecutive times (each detection interval is a certain time, such as 5 seconds), that is, the duration reaches 15 seconds, the state will be converted to 0; for ping delay, if it is greater than or equal to 10ms for 5 consecutive times (each detection interval is 5 seconds), the duration reaches 25 seconds, the state will be converted to 0; the interface status code is similar, if it is a non-200 status code for several consecutive times (set according to business needs) and the duration exceeds the set threshold, the state will be converted to 0.

[0034] In step P302, monitoring indicator characteristic bit modeling is performed according to the Ping detection, the Ping delay, the 0 / 1 state of the interface status code, and the set 0 / 1 state value as shown in Table 2.

[0035]

[0036] Table 2 When calculating the second ideal score and the second actual score of each monitoring indicator characteristic bit, the score of the state 0 is 0, and the score of the state 1 is 1.

[0037] In step P303, a corresponding weight is set according to the degree of influence of each monitoring indicator characteristic bit on the quality of domain name resolution service. In one embodiment, ping activity, as a basic connectivity indicator, is directly related to whether the user can access the service, and the weight is set to 1; ping delay affects the user experience, especially for services with high real-time requirements, and the weight is set to 0.6; the interface status code is related to the execution of business logic, and the weight is set to 0.8. Referring to Table 3, the ideal weighted total score and the actual weighted total score of all monitoring indicator characteristic bits are calculated through weighted calculation, and the weighted ratio is calculated based on the ideal weighted total score and the actual weighted total score.

[0038]

[0039] Table 3 In step S3, by calculating the weighted ratio (the ratio of the weighted total score to the ideal total score) and comparing it with the set threshold, if the weighted ratio is less than the set threshold, it means that the current resolution IP may have problems and needs to be switched. For example, if the weighted ratio is 0.69, which is less than the set threshold (assuming the threshold is 0.8), it means that the overall service quality has declined, and the corresponding resolution IP switching plan is automatically triggered to switch the domain name resolution to the backup IP or other healthier resolution paths to ensure the normal operation of the business.

[0040] Among them, when switching the service domain name resolution IP, first determine the abnormal service domain name resolution IP according to the data reported by the monitoring indicator characteristic bit; then change the data corresponding to the abnormal service domain name resolution IP in the basic characteristic bit to 0, recalculate the first actual score and the first ideal score, and obtain the ratio of the two; finally, determine the basic characteristic bit with abnormality according to the ratio, and switch the service domain name resolution IP.

[0041] In one embodiment, when the actual data reported by the monitoring indicator characteristic bit shows that IP3 is abnormal, the corresponding data in the basic characteristic bit is changed to 0. After the IP3 data is changed to 0, the first actual score of each basic characteristic bit (computer room A, computer room B, operator X, operator Y) is recalculated. After the original count value of IP3 in computer room B and operator X is changed from 1 to 0, the actual total score of computer room B changes from a possible higher value to 2, and the actual total score of operator X also changes accordingly. By recalculating the ratio of the first actual score of each basic characteristic bit to the first ideal score, the degree of deviation of each basic characteristic bit from the ideal state can be intuitively seen. For example, the ratio of computer room B is 0.5, which is less than 1, indicating that there may be many problems with the resolution IP in computer room B, affecting its overall performance; the ratio of operator X is also 0.5, which also indicates that the resolution IP related to the operator may be unstable. Execute the solution of switching to A and Y.

[0042] It should be noted that before executing the business domain name resolution IP switch, check the current domain name resolution status to ensure the feasibility and effectiveness of the switch. If the status is not checked, directly executing the switch may cause conflicts, resulting in resolution confusion or service interruption. For example, if the DNS cache update is currently in progress, executing the switch at this time may cause the cache data to be inconsistent with the new resolution configuration, affecting the normal access of users.

[0043] It can be seen that the domain name resolution switching method provided in the present application performs domain name resolution switching by constructing a model including noise reduction feature bits, basic feature bits and monitoring indicator feature bits, which can adapt to various business deployment architectures and ensure business stability and continuity.

[0044] Based on the same inventive concept, a domain name resolution switching device is also provided in the embodiment of the present application. Since the principle of solving the problem by the device in the embodiment of the present application is similar to the above-mentioned domain name resolution switching method, device, electronic device and storage medium in the embodiment of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0045] As the instruction manual Figure 4 As shown, the present application also provides a domain name resolution switching device, the device comprising: The collection module 401 is used to collect monitoring data of the service domain name resolution IP through the monitoring probe, and perform noise reduction processing on the noise reduction feature bits of the monitoring data to obtain the monitoring data to be analyzed; the noise reduction feature bits include the cloud vendor and the proxy IP; Modeling module 402, used to model the basic characteristic bits of the monitoring data to be analyzed, and calculate the first actual score and the first ideal score of each basic characteristic bit; and model the monitoring indicator characteristic bits of the monitoring data to be analyzed, and calculate the weighted ratio according to the set weight of each monitoring indicator characteristic bit; the basic characteristic bits include the computer room and the operator; the monitoring indicator characteristic bits include Ping detection, ping delay and interface status code; The switching module 403 is used to switch the service domain name resolution IP according to the calculated first actual score and first ideal score of each basic feature bit if the weighted ratio is less than a set threshold.

[0046] In some embodiments, the acquisition module 401 performs noise reduction processing on the noise reduction feature bits of the monitoring data to obtain monitoring data to be analyzed, including: detecting whether the data reported by the cloud vendor or the proxy IP are all abnormal; if the data reported by the cloud vendor or the proxy IP are all abnormal, filtering out the data reported by the cloud vendor or the proxy IP from the monitoring data to obtain monitoring data to be analyzed.

[0047] In some embodiments, the modeling module 402 performs basic feature bit modeling on the monitoring data to be analyzed, and calculates a first actual score and a first ideal score for each basic feature bit, including: performing binary modeling on the computer room and the operator as basic feature bits to obtain a two-dimensional feature matrix; calculating a first ideal score and a first actual score for each basic feature bit based on the feature matrix; the first ideal score and the first actual score are used to respectively represent the total number of times each basic feature bit appears in all business domain name resolution IPs under an ideal operating state and an actual operating state.

[0048] In some embodiments, the modeling module 402 models the monitoring indicator characteristic bits of the monitoring data to be analyzed, and calculates the weighted ratio according to the set weight of each monitoring indicator characteristic bit, including: converting the Ping detection, ping delay and interface status code in the monitoring data to be analyzed into 0 / 1 status respectively through a standardized evaluation strategy; modeling the monitoring indicator characteristic bits according to the 0 / 1 status of the Ping detection, the ping delay and the interface status code and the set 0 / 1 status value, and obtaining the second ideal score and the second actual score of each monitoring indicator characteristic bit; the second ideal score and the second actual score are used to represent the total state value of each monitoring indicator characteristic bit in all business domain name resolution IPs under the ideal operating state and the actual operating state respectively; the ideal weighted total score and the actual weighted total score of all monitoring indicator characteristic bits are calculated according to the corresponding weight set for each monitoring indicator characteristic bit, and the weighted ratio is calculated according to the ideal weighted total score and the actual weighted total score. Wherein, the corresponding weight is set according to the degree of influence of each monitoring indicator characteristic bit on the domain name resolution service quality. Among them, according to whether the Ping probe is qualified, the Ping delay and the interface status code are converted into 0 / 1 state accordingly; wherein, within the set time, if it is detected that the Ping probe is unavailable, the Ping delay is greater than the set delay threshold, and the interface status code is abnormal, it is judged as unqualified and converted into 0 state; otherwise, it is judged as qualified and converted into 1 state.

[0049] In some embodiments, the switching module 403 switches the business domain name resolution IP according to the calculated first actual score and first ideal score of each basic characteristic bit, including: determining the abnormal business domain name resolution IP according to the data reported by the monitoring indicator characteristic bit; changing the data corresponding to the abnormal business domain name resolution IP in the basic characteristic bit to 0, and recalculating the first actual score and the first ideal score, and obtaining the ratio between the two; determining the basic characteristic bit with abnormality according to the ratio, and switching the business domain name resolution IP.

[0050] The application provides a domain name resolution switching device, which collects monitoring data of the service domain name resolution IP through the monitoring probe through the collection module, and performs noise reduction processing on the noise reduction feature bits of the monitoring data to obtain the monitoring data to be analyzed; the basic feature bits of the monitoring data to be analyzed are modeled through the modeling module, and the first actual score and the first ideal score of each basic feature bit are calculated; and the monitoring index feature bits of the monitoring data to be analyzed are modeled, and the weighted ratio is calculated according to the set weight of each monitoring index feature bit; if the weighted ratio is less than the set threshold, the service domain name resolution IP is switched according to the calculated first actual score and the first ideal score of each basic feature bit through the switching module. Thus, by constructing a model including noise reduction feature bits, basic feature bits and monitoring index feature bits, domain name resolution switching is performed, which can adapt to various types of business deployment architectures and ensure business stability and continuity.
