Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to data link management methods, apparatus, computer equipment, and storage media. Background Technology

[0002] Currently, there is no independent data link automatic recovery management mechanism in the industry to provide fine-grained and unified management for such self-recovery scenarios. In the case of unstable data links, this kind of convenient operation and maintenance-lacking automatic recovery may lead to more serious data transmission problems. For example, under poor data link quality, although the system may restore all or part of its service capabilities, it is easy for the link to fail again in the face of subsequent sudden large-volume business scenarios. Ultimately, this will cause some controllers to be unable to carry the front-end business normally, thereby affecting the availability of the system. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a data link management method, apparatus, computer equipment, and storage medium to solve the data transmission problem caused by the inability of the data link to automatically recover, which leads to more serious data transmission issues.

[0004] In a first aspect, embodiments of the present invention provide a data link management method, comprising:

[0005] Obtain the current target operating mode of the link recovery device;

[0006] In the target operating mode, the signal quality level of the data link between the current control boxes is detected, and the front-end service pressure is obtained;

[0007] When the front-end service pressure is less than a preset threshold, a simulation test is performed on the main control device of each control box to obtain the simulation test results, wherein the preset threshold matches the target operating mode;

[0008] Based on the signal quality level and / or the simulation test results, perform corresponding control operations on the data link.

[0009] In an optional implementation, the step of performing a simulation test on the main control device of each control box to obtain the simulation test results includes:

[0017] The step of performing corresponding control operations on the data link based on the signal quality level and / or the simulation test results includes:

[0018] When the signal quality level is greater than or equal to the first preset level, and the simulation test result is that the first performance data is greater than or equal to the first performance data threshold, the data link is controlled to automatically recover after the fault is cleared.

[0019] If the signal quality level is lower than the first preset level, or if the simulation test result shows that the first performance data is lower than the first performance data threshold, a link warning operation is performed.

[0020] If the signal quality level is lower than the first preset level and the simulation test result shows that the first performance data is lower than the first performance data threshold, a link warning operation is performed and a prompt message is generated, wherein the prompt message is used to prompt whether to switch the first mode to the second mode.

[0021] In an optional implementation, when the target operating mode is the second mode, the performance data threshold is the second performance data threshold.

[0022] The step of performing corresponding control operations on the data link based on the signal quality level and / or the simulation test results includes:

[0023] When the signal quality level is greater than or equal to the second preset level, and the simulation test result is that the first performance data is greater than or equal to the second performance data threshold, the data link is controlled to automatically recover after the fault is cleared.

[0024] If the signal quality level is lower than the second preset level, or if the simulation test result shows that the first performance data is lower than the second performance data threshold, a link warning operation is performed.

[0025] When the signal quality level is between the third preset level and the second preset level, and the simulation test result is that the first performance data is less than the second performance data threshold, the data link is controlled to automatically recover after the fault is cleared.

[0026] If the signal quality level is lower than the third preset level, the data link is controlled to automatically recover after the fault is cleared, and the service acceptance service of the data link is suspended.

[0027] In an optional implementation, after controlling the data link to automatically recover after the fault is cleared and suspending the data link from undertaking front-end services, the method further includes:

[0028] Under the specified signal quality level, the main control device of each control box is subjected to multiple simulation tests to obtain the second performance data of the main control chip in each simulation test;

[0029] If the second performance data in each simulation test is greater than or equal to the third performance data threshold, the service acceptance of the data link is restored.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] According to embodiments of the present invention, a data link management method, apparatus, computer device, and storage medium are provided. It should be noted that the steps shown in the flowcharts in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0048] This embodiment provides a data link management method, which can be used in the aforementioned mobile terminals, such as mobile phones and tablet computers. Figure 1 This is a flowchart of a data link management method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0049] Step S11: Obtain the current target operating mode of the link recovery device.

[0050] In this embodiment, the Datalink Automatically Restore (DAR) device operates in two modes: a first mode and a second mode. The first mode is a normal mode, and the second mode is a high-availability mode. The DAR device is deployed in various control boxes, such as... Figure 2 As shown, the control frame includes: front-end devices, main control devices, and link recovery devices. Data acquisition links connect the control frames. The link recovery device can identify its own control frame as its own control frame and the control frames connected to it as its peer control frames. The link recovery device can dynamically manage its own front-end devices, its own main control devices, and the peer control frames' main control devices in both high-availability and normal modes.

[0051] It should be noted that the front-end device of this control frame connects to the service devices, which are typically the user's business servers, etc., and are connected to the front-end device of this control frame via FC / IP / RoCE / IB switches, etc. The DAR device can obtain real-time performance data (IOPS, bandwidth, latency, etc.) of the main control device of this control frame and the control frame's counterpart. The devices in this control frame and the counterpart control frame devices can be interconnected via high-speed links such as FC / IP / RoCE / IB / PCIE (or can share the high-speed link between the devices in this control frame and the counterpart control frame devices), and interlock information such as link quality can be performed.

[0052] Step S12: In the target operating mode, detect the signal quality level of the data link between the current control boxes and obtain the front-end service pressure.

[0053] In this embodiment, under the target operating mode, the DAR device can detect the signal quality of the data link between the current control frames and match the corresponding signal quality level. The DAR device has embedded various signal quality levels for the data link, including multiple levels. The smaller the level number, the better the communication quality. For example, the communication quality level of level 1 is higher than that of level 2, which means that the maximum performance of the controller at level 1 is higher than that at level 2.

[0054] In this embodiment of the application, in order to accurately determine the status of the data link, the DAR device can also obtain the current service pressure through the front-end device of this control frame.

[0055] Step S13: When the front-end business pressure is less than the preset threshold, perform a simulation test on the main control device of each control box to obtain the simulation test results. The preset threshold matches the target operating mode. Each control box includes: the control box itself and the control box to which it is controlled.

[0056] In this embodiment, the preset thresholds for the DAR device differ in different modes. For example, in the first mode (normal mode), the preset threshold C1 corresponds to the service pressure. In the second mode (high availability mode), the preset threshold C2 corresponds to the service pressure. Based on this, after obtaining the front-end service pressure, the DAR device obtains the preset threshold matching the target operating mode and compares the front-end service pressure with the preset threshold. If the front-end service pressure is less than the preset threshold, a simulation test is performed on the main control device of each control frame to obtain the simulation test results.

[0057] In this embodiment, the main control device of each control frame is simulated and tested to obtain simulation test results. This includes: performing performance tests on the main control device of each control frame within a preset time period to obtain first performance data of the main control chip; obtaining a performance data threshold that matches the signal quality level; and comparing the first performance data with the performance data threshold to obtain the simulation test results. The preset time period of the DAR device is different in different modes, and different signal quality levels correspond to different performance data thresholds.

[0058] Specifically, obtaining the performance data threshold matching the signal quality level includes: obtaining the maximum performance data matching the signal quality level and the target ratio matching the target operating mode; calculating the product between the maximum performance data and the target ratio, and using the product as the performance data threshold. For example: the performance data threshold is B, the target ratio corresponding to the first mode is 0.85, and the target ratio corresponding to the second mode is 0.75. In the first mode, the performance data threshold is B × 0.85. In the second mode, the performance data threshold is B × 0.75.

[0059] As an example, if the target operating mode is the first mode (normal mode), obtain the preset time period T1 corresponding to the normal mode and the performance data threshold B×0.85 corresponding to the signal quality level. Within the preset time period T1, perform performance tests on the main control device of each control box to obtain the first performance data a (IOPS, bandwidth, latency, etc.) of the main control chip. Then, compare the first performance data a with the performance data threshold B×0.85 to obtain the simulation test results.

[0060] Alternatively, if the target operating mode is the second mode (high availability mode), obtain the preset time period T2 corresponding to the normal mode and the performance data threshold B×0.75 corresponding to the signal quality level. Within the preset time period T2, perform performance tests on the main control device of each control box to obtain the first performance data a (IOPS, bandwidth, latency, etc.) of the main control chip. Then, compare the first performance data a with the performance data threshold B×0.75 to obtain the simulation test results.

[0061] Step S14: Based on the signal quality level and / or simulation test results, perform corresponding control operations on the data link.

[0062] In this embodiment of the application, when the target operating mode is the first mode, the performance data threshold is the first performance data threshold.

[0063] In this application embodiment, based on the signal quality level and / or simulation test results, corresponding control operations are performed on the data link, including the following situations:

[0064] (1) When the signal quality level is greater than or equal to the first preset level and the simulation test result is that the first performance data is greater than or equal to the first performance data threshold, the control data link is automatically restored after the fault is cleared.

[0065] (2) When the signal quality level is less than the first preset level, or when the simulation test result shows that the first performance data is less than the first performance data threshold, the link warning operation is executed.

[0066] (3) When the signal quality level is less than the first preset level and the simulation test result is that the first performance data is less than the first performance data threshold, the link warning operation is executed and a prompt message is generated, wherein the prompt message is used to prompt whether to switch the first mode to the second mode.

[0067] As an example, in normal mode, the DAR device divides the signal quality of the data link into 5 levels, with level 1 providing the best communication quality and level 5 providing the worst. Within a 30-minute time period, the DAR device continuously monitors the signal quality level between current control frames, and it performs a simulation test (ST) when the front-end service load is below a preset threshold.

[0068] If the simulation test result shows that the performance data a is greater than or equal to B×85%, and the signal quality level of the data link is greater than or equal to level 3, the data link can automatically recover after the fault is cleared.

[0069] If the simulation test result shows that the performance data 'a' is less than 85% of 'B', or the signal quality level of the data link is lower than level 3, then a level 1 link warning will be reported.

[0070] If the simulation test result shows that the performance data 'a' is less than 85% of 'B', and the signal quality level of the data link is lower than level 3, a level 1 link alarm will be reported. In this case, the data link cannot be automatically restored after the fault is cleared, and you need to be prompted whether to switch to high availability mode.

[0071] In this embodiment of the application, when the target operating mode is the second mode, the performance data threshold is the second performance data threshold.

[0072] In this application embodiment, based on the signal quality level and / or simulation test results, corresponding control operations are performed on the data link, including the following situations:

[0073] (1) When the signal quality level is greater than or equal to the second preset level, and the simulation test result is that the first performance data is greater than or equal to the second performance data threshold, the control data link is automatically restored after the fault is cleared.

[0074] (2) When the signal quality level is less than the second preset level, or when the simulation test result shows that the first performance data is less than the second performance data threshold, a link warning operation is performed.

[0075] (3) When the signal quality level is between the third preset level and the second preset level, and the simulation test result is that the first performance data is less than the second performance data threshold, the control data link will automatically recover after the fault is cleared.

[0076] (4) When the signal quality level is less than the third preset level, the control data link will automatically recover after the fault is cleared and the data link service will be suspended.

[0077] In this embodiment of the application, after the control data link is automatically restored after the fault is cleared and the data link is suspended from undertaking front-end services, the method further includes: performing multiple simulation tests on the main control device of each control box under the signal quality level to obtain the second performance data of the main control chip in each simulation test; and restoring the service undertaking service of the data link when the second performance data of each simulation test is greater than or equal to the third performance data threshold.

[0078] In this embodiment of the application, before the second performance data is greater than or equal to the third performance data threshold, the method further includes: obtaining the preset ratio corresponding to the third preset level; and calculating the third performance threshold based on the maximum performance data corresponding to the second mode and the preset ratio.

[0079] As an example, in high-availability mode, the DAR device divides the signal quality of the inter-frame data link into 20 levels, with level 1 providing the best communication quality and level 20 providing the worst. Within a 20-minute time period, the DAR device continuously monitors the signal quality level of the current control frame inter-frame data link, and performs a simulation test when the front-end service load is below a preset threshold.

[0080] If the simulation test result shows that the performance data a is greater than or equal to B×75%, and the signal quality level of the data link is greater than or equal to 12 levels, the data link can be automatically restored after the fault is cleared.

[0081] If the simulation test result shows that the performance data 'a' is less than 75% of 'B', or the signal quality level of the data link is lower than 12, then a secondary link warning will be reported.

[0082] If the simulation test result shows that the performance data a is less than B×75% and the signal quality level of the data link is lower than level 12, a secondary link alarm will be reported. If the signal quality level of the data link is not lower than level 15, the data link can be automatically restored after the fault is cleared.

[0083] If the signal quality level of the data link is lower than 15, the data link will be restored after the fault is cleared. However, the data link will not take over front-end services. Instead, a simulation test will be conducted for 35 minutes. If the performance data is greater than or equal to B×70% under the current signal quality level, the front-end service will be restored immediately.

Simultaneously, the link recovery device also acquires the signal quality level of the data links between control boxes, and finally controls the data links based on the simulated test results and signal quality levels, achieving dynamic management of the data links between control boxes and preventing link anomalies caused by high front-end service pressure.
