Description

Technical Field

[0001] This invention relates to the field of data synchronization technology, and more specifically, to a data synchronization method, apparatus, electronic device, and storage medium. Background Technology

[0002] In modern communication networks, wavelength division multiplexing (WDM) technology has become a key means to achieve high-capacity data transmission. Especially in optical networks, box-type WDM equipment, as a core component, needs to frequently synchronize data with the network management controller to ensure real-time network monitoring and smooth service operation.

[0003] However, traditional data synchronization technologies primarily employ multi-threaded interaction with devices. This multi-threaded approach leads to frequent data reading and transmission by the device, especially under conditions of limited device processing power or unstable network environments. Devices may malfunction due to excessive stress, resulting in prolonged response times or even disconnections, impacting network stability and device lifespan. Furthermore, an excessive number of synchronization request threads significantly increases system resource consumption for the synchronization service, potentially causing service anomalies such as memory overflows and high CPU usage, affecting the normal operation of the synchronization service and overall system performance. In addition, in high-concurrency scenarios, data synchronization efficiency is severely constrained by thread competition and waiting, increasing synchronization latency and failing to meet the real-time requirements of demanding business applications.

[0033] Figure 1 This is a flowchart of a first data synchronization method according to one embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0034] Step S101: Obtain the target synchronization request from the cache server. The target synchronization request is sent from the synchronization server to the cache server.

[0035] Specifically, the target device periodically or under the trigger of a specific event retrieves the target synchronization request pre-sent by the synchronization server from the cache server.

[0036] It should be noted that in traditional data synchronization methods, the synchronization server directly sends requests to the device. However, this application stores these requests in a cache server, allowing the device to selectively retrieve the requested information based on its task requirements and workload. In this application, the direct interaction between the synchronization server and the device is replaced by indirect processing through the cache server. This reduces the direct communication burden on the device and avoids excessive consumption of device resources due to frequent synchronization requests. Simultaneously, as an intermediary layer, the cache server can flexibly schedule and store synchronization requests based on the real-time status of the device and the overall system resource situation, making data exchange more efficient and intelligent. With the intervention of the cache server, even if the synchronization server or network fails, the device can still obtain the requested information from the cache server, ensuring the continuity and reliability of the data synchronization process.

[0037] Step S102: Obtain the target pressure value of the target device.

[0038] Specifically, before processing a synchronization request, the target device needs to assess its own status, i.e., obtain the target stress value. This stress value includes, but is not limited to, the device's CPU utilization, memory usage, network bandwidth utilization, and device health status. The purpose of obtaining the target device's target stress value is to ensure that the device will not experience performance degradation or abnormal behavior due to insufficient resources when processing synchronization requests.

[0039] Specifically, the device's built-in monitoring system periodically checks its operational status, including hardware resource usage and software performance, to determine stress levels. The device then feeds back the monitored stress levels to the synchronization server or cache server in real time or periodically, serving as the basis for subsequent data synchronization decisions.

[0040] Step S103: In response to the target pressure value being less than a preset threshold, the target synchronization data is written to the cache server, wherein the target synchronization data is stored in the target device.

[0041] Specifically, when the target device determines that its pressure value is less than a preset threshold, it indicates that the device currently has sufficient resources to handle the data synchronization task. At this time, the device begins to collect target synchronization data and writes it to the cache server, rather than directly transmitting it to the synchronization server.

[0042] Specifically, when resource conditions allow, the device begins to asynchronously collect the information that needs to be synchronized from the data source. This reduces the direct correlation between data collection and transmission, allowing the device to complete data synchronization without affecting the current running tasks.

[0043] Specifically, the target synchronization data is stored in a cache server instead of being directly transmitted to the synchronization server. This reduces the processing pressure on the synchronization server and improves the efficiency of data transmission.

[0044] Specifically, after the device finishes writing the data to the cache server, it sets a completion flag to inform the synchronization server that the data is ready and awaiting further processing by the synchronization service. This mechanism ensures the integrity and reliability of the data, while also avoiding unnecessary operations such as the synchronization server requesting the same data multiple times.

[0045] In this embodiment of the invention, a target synchronization request is obtained from a cache server, and the target synchronization request is sent from a synchronization server to the cache server; the target pressure value of the target device is obtained; in response to the target pressure value being less than a preset threshold, target synchronization data is written to the cache server, wherein the target synchronization data is stored on the target device. This invention, by utilizing a cache server and determining the target pressure value of the target device, achieves the goal of realizing an efficient, stable, and controllable data synchronization process, thereby significantly improving the efficiency and reliability of data synchronization, reducing device pressure, and optimizing the use of service resources. This solves the technical problems of excessive device pressure and excessive resource consumption caused by existing technologies during data synchronization.

[0046] Optionally, obtaining the target synchronization request from the cache server in step S101 may include the following steps:

[0047] Step S201: Obtain the result of the synchronization server's judgment on the target health value of the target device;

[0048] Specifically, the synchronization server continuously monitors the device status, collecting device performance metrics and health data. Based on the status information reported by the device, operation logs, and historical performance data, the synchronization server comprehensively assesses the health status of the target device and obtains a judgment result on the target health value of the target device.

[0049] Specifically, the target health value is an important indicator for measuring the current operating status of a device, reflecting its processing capacity, network connectivity, and overall health. This assessment can be obtained proactively, such as by the device periodically requesting health status from a synchronization server, or passively, by the synchronization server proactively sending health status information to the device when it detects changes in the device's status.

[0050] Specifically, the synchronization server performs comprehensive analysis on the collected data and calculates the target health value of the device based on a preset algorithm or model. This value can be dynamically adjusted to adapt to different device characteristics and network environments.

[0051] Step S202: In response to the judgment result indicating that the target health value is less than the preset value, query whether there is a target synchronization request in the cache server;

[0052] Specifically, after receiving the health value assessment results, the device will make the next decision based on the results.

[0053] Specifically, if the assessment result indicates that the device's target health value is below a preset threshold, this usually means that the device is currently under high load or in an unstable state. Directly processing synchronization requests may increase the device's burden or even cause it to malfunction. Therefore, the device does not directly respond to synchronization requests but instead redirects to the cache server to check if there are any pending synchronization requests. The cache server acts as a storage and scheduling center for synchronization requests, allowing the device to query and retrieve pending requests, thus avoiding the direct communication burden on the device under high pressure.

[0054] The above operations reduce the direct communication pressure on devices. By using a cache server as an intermediary, devices can flexibly choose whether and when to process synchronization requests based on their own status.

[0055] Step S203: In response to the existence of a target synchronization request in the cache server, obtain the target synchronization request from the cache server.

[0056] Specifically, if there are target synchronization requests in the cache server, the target device will read and retrieve these requests from the cache server and begin the data synchronization process.

[0057] It's important to note that devices intelligently retrieve synchronization requests from the cache server based on their own health status, rather than passively waiting for direct requests from the synchronization server. This makes the data synchronization process more flexible and efficient. Simultaneously, the cache server must ensure data integrity and timely updates so that target devices can obtain accurate and up-to-date data when querying and retrieving synchronization requests.

[0058] In addition, the asynchronous processing mechanism allows the device to proactively process synchronization requests in the cache when the pressure is low, avoiding data processing under high pressure and ensuring the stability and reliability of data synchronization.

[0059] Optionally, the data synchronization method further includes: receiving a target synchronization request sent by a synchronization server in response to a judgment result indicating that the target health value is greater than or equal to a preset value.

[0060] Specifically, if the results of the synchronization server's evaluation indicate that the target device's health value is greater than or equal to the preset value, it means that the device is currently in good condition and can effectively handle synchronization requests.

[0061] Specifically, after confirming its own good condition, the target device will directly receive a synchronization request from the synchronization server and begin the data collection and synchronization process according to the request content. This process includes, but is not limited to, data reading, formatting, data packet construction, and data uploading, ultimately completing the processing of the synchronization request and returning a response to the synchronization server. When the device is in good health, this process can be carried out quickly and efficiently, thereby improving the overall speed of data synchronization and system performance.

[0062] Specifically, after processing a synchronization request, the device reports its latest status information to the synchronization server. The synchronization server then updates the target device's health value accordingly, providing the latest data support for subsequent synchronization request decisions. This mechanism ensures real-time updates to the device's health value, providing a more accurate basis for subsequent data synchronization decisions.

[0063] Understandably, once the target device is confirmed to be in a stable and healthy state, the synchronization server will directly send the target synchronization request without going through the cache server. Direct connection and data exchange reduce intermediate steps in data transmission, improve the real-time performance and efficiency of data synchronization, and also reduce the burden on the cache server, optimizing the allocation of system resources.

[0064] It should be noted that the preset values ​​need to take into account the device's processing capacity and the resource requirements of the synchronization requests, so as to ensure that the device can directly receive synchronization requests when the device is stable or resources are sufficient, thereby improving data synchronization efficiency.

[0065] Optionally, the data synchronization method may further include the following steps:

[0066] Step S301: In response to the target pressure value being greater than a preset threshold, the target pressure value is cyclically detected;

[0067] Specifically, when the stress value of the target device (such as CPU utilization, memory usage, network bandwidth usage, etc.) exceeds a preset threshold, it indicates that the device is currently under high load and may not be able to effectively handle additional data synchronization tasks, or even cause device failure. To avoid this situation, this invention employs a cyclic detection mechanism to continuously monitor the device's stress value until it falls back to a safe range.

[0068] Specifically, the target device's built-in monitoring system or external monitoring service continuously monitors the target device's operating status, including the usage of hardware resources and the operation of software, to ensure that changes in the device's stress can be detected in a timely manner.

[0069] Specifically, once the system detects that the device stress value exceeds the preset threshold, it will immediately take measures to stop receiving new synchronization requests to prevent further overload of the device.

[0070] It should be noted that when the device enters a high-pressure state, the system will not immediately stop data synchronization. Instead, it will continuously monitor the pressure changes of the target device through a cyclic detection mechanism until the pressure returns to below the preset threshold.

[0071] In step S302, in response to detecting that the target pressure value is less than a preset threshold, the target synchronization data is written to the cache server.

[0072] Specifically, when the cyclic detection mechanism confirms that the pressure value of the device has dropped to a safe level, that is, less than the preset threshold, the target device begins to process the data synchronization task. However, in order to avoid the target device being subjected to excessive pressure again, the synchronization data is not sent directly to the synchronization server, but is first written to the cache server, which is then uniformly scheduled and managed by the cache server.

[0073] Specifically, the device uses a cache server as a temporary storage location for data, avoiding direct data exchange with the synchronization server under high pressure, thereby achieving reasonable resource allocation and effective pressure relief.

[0074] Specifically, once the data is written to the cache server, the worker thread of the synchronization service is awakened to process the data and finally synchronize it into the database, thereby ensuring the integrity and timeliness of the data.

[0075] Specifically, data written to the cache server can be shared and processed by multiple worker threads, without relying on the direct response of a single synchronization service, thus improving the stability and efficiency of data synchronization.

[0076] By employing a cyclic detection mechanism when the device pressure exceeds a preset threshold, and only writing data to the cache server after the pressure returns to a safe level, the system effectively avoids device failure due to resource overload, while ensuring the continuity and efficiency of data synchronization. This intelligent pressure management and data caching solution provides strong technical support for the stable operation and data synchronization of box-type wavelength division multiplexing (WDM) equipment in large-scale communication networks, and has significant innovative value and application potential.

[0077] Figure 2 This is a flowchart of a second data synchronization method according to one embodiment of the present invention, such as... Figure 2 As shown, the method includes the following steps:

[0078] Step S401: Obtain the target health value of the target device.

[0079] Specifically, the synchronization server continuously monitors the operating status of the target device, collects real-time performance indicators such as CPU utilization, memory usage, network latency, and anomaly reporting frequency, and calculates the target health value of the target device.

[0080] The target health value is obtained based on the status information and operation logs reported by the device, as well as the comprehensive analysis of the synchronization server. The target health value can accurately reflect the actual operating status and carrying capacity of the device.

[0081] It should be noted that the target health status of the target equipment needs to be monitored and evaluated in real time to ensure that the data synchronization strategy can be flexibly adjusted according to the real-time health status of the equipment, so as to avoid the equipment operating under high pressure and thus reduce the equipment failure rate.

[0082] In step S402, in response to the target health value being less than a preset value, a target synchronization request is sent to the cache server.

[0083] Specifically, when the synchronization server detects that the health value of the target device is lower than a preset threshold, it indicates that the device may be under high pressure and should not be directly received and processed for synchronization requests. To avoid increasing the device's burden, the synchronization server sends the target synchronization request to the cache server instead of sending it directly to the target device.

[0084] By using a caching server as an intermediary, it is possible to effectively avoid devices directly processing synchronization requests under high pressure, reduce the immediate burden on devices, and improve the overall stability and efficiency of the system.

[0085] It should be noted that the preset values ​​are based on an understanding of the normal operating status of the equipment, ensuring that appropriate measures can be taken to protect the stable operation of the equipment when its health is poor.

[0086] Step S403: Loop through the cache server to check if the target synchronization data exists, wherein the target synchronization data includes the target synchronization flag.

[0087] Specifically, after sending the target synchronization request to the cache server, the synchronization server will periodically or continuously query the cache server to see if there is any synchronization data uploaded by the target device.

[0088] Specifically, during the query process, the target synchronization data is marked with a target synchronization flag so that the synchronization server can accurately identify and process it.

[0089] Meanwhile, the loop query mechanism ensures timely data synchronization, avoids data backlog and loss, and also reduces the direct dependence of the synchronization server on the device status, thereby improving the utilization efficiency of system resources.

[0090] Step S404: In response to the existence of target synchronization data in the cache server, a write operation is performed on the target synchronization data.

[0091] Specifically, once the synchronization server detects the synchronization data uploaded by the target device from the cache server, it will immediately perform a write operation on this data and store it in the database of the synchronization service, thus completing the final data synchronization.

[0092] Specifically, write operations need to ensure data integrity and consistency, and also need to process duplicate data to avoid data redundancy in the database.

[0093] Timely data write operations ensure the continuity and efficiency of data synchronization, while a duplicate data processing mechanism guarantees data consistency and reliability.

[0094] The data synchronization method of this invention intelligently schedules data synchronization requests to a cache server when the device's health is poor. Then, it iteratively queries the cache server to check for the existence of synchronization data uploaded by the target device before finally performing a data write operation. This effectively avoids direct data processing under high pressure, reducing the immediate burden on the device, while ensuring the continuity and efficiency of data synchronization. It achieves dynamic matching between device health status and data synchronization strategy, improving the overall stability and efficiency of the system. This data synchronization scheme provides a more intelligent, efficient, and stable data synchronization solution for box-type wavelength division multiplexing (WDM) equipment in large-scale communication networks, possessing significant technical value and application prospects.

[0095] Optionally, the data synchronization method further includes: in response to a target health value being greater than or equal to a preset value, sending a target synchronization request to the target device.

[0096] Specifically, when the health status assessment result of the target device shows that its target health value meets the preset standard, the synchronization service will directly send a data synchronization request to the target device, skipping the intermediate link of the cache server.

[0097] The advantages of this strategy are: direct communication reduces intermediate steps in data transmission, improves the real-time performance and response speed of data synchronization, and ensures that data can be quickly updated to the synchronization service; since the current state of the device is suitable for handling synchronization requests, direct communication avoids the additional scheduling of cache servers and the consumption of data storage resources, thereby improving the efficiency of data synchronization and reducing the waste of system resources; when the device is in good health, direct communication will not put additional pressure on the device, which helps to maintain the stable operation of the device and extend its service life.

[0098] Specifically, after receiving a synchronization request, the target device begins collecting and processing data based on the request content. Once processing is complete, the device directly returns the synchronized data to the synchronization service, eliminating the need for a cache server and further improving data transmission efficiency and real-time performance.

[0099] Figure 3 This is a flowchart illustrating a data synchronization method according to one embodiment of the present invention, such as... Figure 3 As shown, the specific steps to achieve data synchronization include:

[0100] The first step is to calculate the health score of the target equipment, which is used to measure the actual operating condition and load-bearing capacity of the equipment.

[0101] The second step is to compare the calculated health value of the target device with the preset health value. If the health value of the target device is greater than or equal to the preset health value, the target device is determined to be in a healthy state. If the health value of the target device is less than the preset health value, the target device is determined to be in an unhealthy state.

[0102] Third, if the target device is in a healthy state, the synchronization server will directly send the target synchronization request to the target device.

[0103] Fourth, if the target device is in an unhealthy state, the synchronization server adds the target synchronization request to the request queue and sends it to the cache server;

[0104] The fifth step is for the target device to assess its own hardware resource usage and software operation status to determine its target stress value. If the current target stress value is within a safe range, the target device actively obtains a synchronization request from the cache server and performs the synchronization operation.

[0105] The sixth step is to process the data that needs to be synchronized and then return the synchronized data to the cache server.

[0106] Step 7: The synchronization server continuously queries the cache server to see if there is any synchronization data uploaded by the target device. When the synchronization server detects the synchronization data uploaded by the target device in the cache server, it wakes up the worker thread, performs a write operation on the uploaded synchronization data, stores it in the database of the synchronization service, completes the final data synchronization, and the worker thread enters a thread sleep state.

[0107] This invention also provides two data synchronization devices for implementing the above embodiments and preferred embodiments, which will not be repeated hereafter.
