Specific embodiments

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0018] With the continuous deepening of human space exploration activities, the demand for space network communication is increasing day by day. High-reliability communication is an important foundation for the construction of system functions such as data transmission, distributed computing, satellite interconnection, giant constellations, and integration of space-air-ground networks. However, the space environment is complex and changeable, facing challenges such as high radiation, extreme temperatures, and long-distance transmission, which pose extremely high requirements for the reliability of network communication. Therefore, it is very important to accurately evaluate the reliability of network communication. Based on the evaluation results, relevant factors of network communication can be optimized, which helps to further improve the reliability of network communication.

[0019] Based on this, the present application proposes a method for evaluating the reliability of communication execution. First, after a service instruction is issued, the reliability of the communication link is quantitatively evaluated by assessing various performance indicators of the communication link, and accurate communication link reliability data is obtained. Then, after the receiving device returns a response message, the response situation of the service instruction is further determined according to the type of the service instruction, and based on this, the reliability of the service instruction execution is evaluated to obtain instruction execution reliability data, which can accurately reflect the reliability of the instruction during the execution process of the receiving device. Finally, by integrating the communication link reliability data and the instruction execution reliability data, accurate service instruction communication execution reliability data is obtained. According to this embodiment, when analyzing the communication execution reliability data of the service instruction, the root cause of the problem can be traced back inversely to determine whether it is due to insufficient communication link reliability or instruction execution reliability problems. Once the root cause of the low reliability is clarified, more specific reliability indicators can be further traced and determined. Through this process, a clear direction can be provided for the optimization of subsequent service instruction communication, and a quantitative basis can be provided for formulating optimization measures, thereby helping to further improve the reliability of service instruction communication.

[0020] In the related art, due to problems such as signal attenuation, frame data loss, and increased latency in the space environment, network communication is unstable and it is difficult to meet the requirements of actual target application tasks through the underlying communication protocol. Based on this, the present application also provides a scenario example of a method for improving the reliability of communication execution and evaluating the reliability of communication execution. This method does not depend on a specific communication protocol, can be deployed and run in a middleware mode, and realizes plug-and-play. Please refer to Figure 1a : S1001. A middleware for improving communication reliability and evaluating the reliability of communication execution is deployed on the sending device. The communication terminal can initiate a target application task, which may include several service instructions. A service instruction is the smallest unit of the target application task; S1002. Input the relevant information of the target application task into the middleware, including each service instruction and the relevant parameters required for evaluating the reliability of communication execution of the service instruction; S1003. The middleware sets a priority level for the service instruction according to the correspondence between the service instruction and the priority, which may include four priorities: urgent, high, medium, and low; S1004. Write the relevant communication data such as the target application task, service instruction, priority level, sending device, and receiving device into a structured database as the initial service instruction communication log; S1005. Write all the service instruction data of the target application task into the cache database so that the service instructions can be quickly read from it; when the execution of a certain service instruction reaches a preset standard, it will be deleted from the cache database; the preset standard can be that the execution of an urgent or high-priority service instruction is successful and the reliability evaluation data has been written into the structured database, the response information of medium- and low-priority service instructions is received, and the reliability evaluation data has been written into the structured database. S1006. When it is determined that the network communication status is normal, send the service instructions to the receiving terminal asynchronously; if the network communication status is abnormal when sending a certain service instruction, the service instruction needs to wait for the processing of the instruction inspection timer; after a service instruction is sent, if it is determined that the sending fails, the service instruction also needs to wait for the processing of the instruction inspection timer. S1007. After the service instruction is sent successfully, wait for its response information; if the response information is not received within the specified time, the service instruction needs to wait for the processing of the instruction inspection timer. S1008. If the response information of the service instruction is received within the specified time, parse it and obtain the instruction execution result from the parsing result, and determine whether the service instruction is executed successfully at the receiving terminal; when the execution fails, determine whether the service instruction belongs to urgent or high-priority. If so, the service instruction needs to wait for the processing of the instruction inspection timer. S1009. The instruction inspection timer obtains the set of service instructions that have not been deleted in the cache database within a preset time period (such as 120 seconds), and monitors the reception of the response information of the service instructions and the instruction execution result obtained through parsing. S1010. At the end of the preset time period, the instruction inspection timer screens out the urgent and high-priority service instructions that have been executed successfully and the medium- and low-priority service instructions that have received response information from the set of service instructions that have not been deleted, and sorts the remaining service instructions from high to low according to the priority. S1011. When it is determined that the network communication status is normal, send the service instructions that need to be re-executed asynchronously. S1012. The middleware contains a reliability evaluation model. By inputting the relevant parameters and target indicators of the communication execution reliability evaluation into this model, a quantitative communication execution reliability evaluation can be carried out on the service instructions that have been executed successfully and the medium- and low-priority service instructions that have not been executed successfully; among them, the target indicators include bit error rate, packet loss rate, link delay situation, link jitter situation, instruction response time, and instruction execution success rate. By inputting the above target indicators into the reliability evaluation model and through calculation, the communication execution reliability data of the service instructions can be obtained; based on the communication execution reliability data of all service instructions, the communication execution reliability data of the target application task can also be obtained. S1013. Update data such as the execution result, status information, and reliability evaluation of the service instruction into the structured database; S1014. Delete the corresponding service instruction in step S1013 from the cache database.

[0021] In the above scenario example, it is possible to implement full-process and full-time monitoring and management of the communication execution of service instructions, and perform hierarchical management of service instructions, ensuring that service instructions with higher priorities are executed first and their execution is successful, thereby improving the reliability of communication execution in the case of intermittent network instability; at the same time, it is possible to perform a quantitative evaluation with relatively high accuracy on the communication execution reliability of service instructions or application tasks. When analyzing the communication execution reliability data of service instructions, the root cause of the problem can be traced back in reverse through the saved service instruction communication logs, providing a clear direction for the optimization of subsequent service instruction communication and a quantitative basis for formulating optimization measures, thereby helping to further improve the reliability of service instruction communication.

[0022] According to an embodiment of the present application, an embodiment of a communication execution reliability evaluation method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0023] In this embodiment, a communication execution reliability evaluation method is provided. Please refer to Figure 1b , and the method includes: S110. When the sending device issues a service instruction to the communication link, determine the bit error rate, packet loss rate, link delay situation, and link jitter situation of the communication link.

[0024] Among them, a service instruction can be a clear instruction issued by a computer or a user to trigger a specific operation or process, usually containing specific information about the specific operation or process to be triggered, such as operation type, parameters, target object, etc.

[0025] The sending device is communicatively connected to the receiving device. The sending device can be a device that initiates service instructions or other data transmissions in a communication system, such as a computer, a mobile phone, or other intelligent terminals. The receiving device can be a device that receives service instructions, processes them, and returns the instruction response situation, such as a computer, a mobile phone, or other intelligent terminals, remote sensing satellites, etc.

[0026] The communication link can be a wireless communication path for transmitting service instructions or other data in space communication. It should be noted that the communication execution reliability evaluation method in the present application can also be used in non-space communication scenarios. For example, in a wired communication scenario, the communication link can also be an optical fiber, a broadband connection, etc.

[0027] The bit error rate can be the ratio of the number of errors in the data transmitted through a communication link within a certain period of time. The packet loss rate can be the ratio of the number of lost data packets to the total number of transmitted data packets within a certain period of time. The link delay situation can be the time required for data to travel from the sender to the receiver. The link jitter situation can be the change in delay during data transmission, for example, it can be represented by the standard deviation of the link delay situation.

[0028] In some embodiments, after the sending device issues one or more service instructions to the communication link and until the return instruction response situation of the receiving device is received, the bit error rate, packet loss rate, link delay situation, and link jitter situation of the communication link are obtained through a network performance testing tool. Exemplarily, they can be obtained multiple times and averaged to obtain the final data of the bit error rate, packet loss rate, link delay situation, and link jitter situation of the communication link.

[0029] S120. Evaluate the link reliability of the communication link based on the bit error rate, packet loss rate, link delay situation, and link jitter situation to obtain the communication link reliability data corresponding to the service instruction during transmission.

[0030] Among them, the link reliability evaluation can be a quantitative evaluation of the communication link based on the evaluation data of the bit error rate, packet loss rate, link delay situation, and link jitter situation. The communication link reliability data can be the data obtained by quantitatively evaluating the link reliability.

[0031] In some embodiments, there is a corresponding relationship between the bit error rate, packet loss rate, link delay situation, link jitter situation, and their evaluation data. After obtaining the bit error rate, packet loss rate, link delay situation, and link jitter situation of the service instruction during transmission, according to this corresponding relationship, the bit error rate evaluation data , packet loss rate evaluation data , link delay evaluation data and link jitter evaluation data are obtained.

[0032] In some embodiments, based on the order relation method, the influence degrees of the bit error rate, packet loss rate, link delay situation, and link jitter situation on the communication link reliability can be determined. Exemplarily, the influence degrees of the bit error rate, packet loss rate, link delay situation, and link jitter situation are respectively , , , , .

[0033] In some embodiments, according to the respective evaluation data of the bit error rate, packet loss rate, link delay condition, and link jitter condition, as well as their respective degrees of influence on the reliability of the communication link, the reliability data of the communication link corresponding to the service instruction during transmission is obtained. Exemplarily, the communication link reliability data , where is the communication link reliability data, is the bit error rate evaluation data, is the packet loss rate evaluation data, is the link delay evaluation data, is the link jitter evaluation data, , , , are the degrees of influence of the bit error rate, packet loss rate, link delay condition, and link jitter condition, respectively.

[0034] S130. When the sending device receives the response information of the receiving device to the service instruction, determine the instruction response situation of the service instruction based on the type of the service instruction.

[0035] Among them, the instruction response situation is used to describe the execution situation of the service instruction on the receiving device, and may include the instruction response time and the instruction execution success rate. The type of the service instruction may be system type, important module type, ordinary module type, and others.

[0036] In some embodiments, if the type of the service instruction is system type or important module type, and the instruction execution result in its response information is failure, then the service instruction needs to be executed again until it is successful. According to the response information when the execution is successful, determine the instruction response situation, that is, the instruction response time and the instruction execution success rate. If the type of the service instruction is ordinary module type or others, whether the instruction execution result in its response information is successful or failure, the instruction response time and the instruction execution success rate can be determined according to the response information.

[0037] In some embodiments, the instruction response time may be the time from when the service instruction is sent from the sending device to when its response information is received. Exemplarily, the type of the service instruction is system type. The t1 time is sent from the sending device, and the t2 time receives its response information. After parsing the response information, the execution result is obtained as failure. The service instruction is sent again, the sending time is t3, the time to receive its response information is t4, and after parsing the response information, the execution result is obtained as successful. Then the response time △t of the service instruction = t4 - t3. Exemplarily, the type of the service instruction is ordinary module type. The t5 time is sent from the sending device, and the t6 time receives its response information. After parsing the response information, the execution result is obtained as failure. The response time △t of the service instruction = t6 - t5.

[0038] In some embodiments, the instruction execution success rate of any service instruction can be calculated by accumulating the current data and historical data of the service instruction at the corresponding receiving terminal. Each service instruction, receiving terminal identifier, and execution result can be recorded in a structured database, and the instruction execution success rate can be calculated based on these records. Exemplarily, the historical record of service instruction A in the database is: executed 99 times on receiving terminal D, among which, 96 times were successful and 3 times were failed. Currently executed 1 time and the execution was successful. After accumulating the current data and historical record data, the execution success rate of this service instruction is 0.97. It should be noted that the accumulated data can reflect the execution situation of the service instruction on the receiving terminal, can accurately evaluate the success rate of the instruction, and avoids the accidental influence of the single execution result.

[0039] S140. Perform an execution reliability evaluation according to the instruction response situation to obtain the instruction execution reliability data corresponding to the service instruction during the execution process.

[0040] Among them, the execution reliability evaluation of the service instruction can be based on the reliability evaluation of the instruction response time and the instruction execution success rate. The instruction execution reliability data can be numerical data reflecting whether there is an abnormality during the instruction execution process, and can be used for further analysis and optimization of the instruction execution process.

[0041] In some embodiments, there is a corresponding relationship between the instruction response time, the instruction execution success rate, and their evaluation data. After obtaining the instruction response time and the instruction execution success rate of the service instruction, according to this corresponding relationship, the instruction response time evaluation data and the instruction execution success rate evaluation data .

[0042] In some embodiments, according to expert experience, the influence degrees of the instruction response time and the instruction execution success rate on the execution reliability of the service instruction can be determined. Exemplarily, the influence degrees of the instruction response time and the instruction execution success rate are respectively 、 , .

[0043] In some embodiments, according to the respective evaluation data of the instruction response time and the instruction execution success rate, and their respective influence degrees on the execution reliability, the instruction execution reliability data during the execution process of the service instruction is obtained. Exemplarily, the instruction execution reliability data , where is the instruction execution reliability data, is the instruction response time evaluation data, is the instruction execution success rate evaluation data, 、 They are the influence degrees of the instruction response time and the instruction execution success rate respectively.

[0044] S150. Summarize based on the communication link reliability data and the instruction execution reliability data to obtain the communication execution reliability data of the service instruction.

[0045] Among them, the communication execution reliability data is used to describe the communication execution situation of the service instruction.

[0046] In some embodiments, according to expert experience, the influence degrees of the communication link reliability data and the instruction execution reliability data on the communication reliability can be determined. Exemplarily, the influence degrees of the communication link reliability data and the instruction execution reliability data are 、 , 。

[0047] In some embodiments, according to the communication link reliability data, the instruction execution reliability data, and their respective influence degrees on the communication reliability, the communication execution reliability data of the service instruction is obtained , where P is the communication execution reliability data of the service instruction, is the communication link reliability data, is the instruction execution reliability data, is the influence degree of the communication link reliability data, is the influence degree of the instruction execution reliability data.

[0048] In the above embodiments, first, after the service instruction is issued, by evaluating various performance indicators of the communication link, the reliability of the communication link is quantitatively evaluated to obtain accurate communication link reliability data. Then, when the receiving device returns the response information, according to the type of the service instruction, the response situation of the service instruction is further determined, and based on this, the reliability of the service instruction execution is evaluated to obtain the instruction execution reliability data, which can accurately reflect the reliability of the instruction during the execution process of the receiving device. Finally, by integrating the communication link reliability data and the instruction execution reliability data, accurate communication execution reliability data of the service instruction is obtained. According to this embodiment, when analyzing the communication execution reliability data of the service instruction, the root cause of the problem can be traced back, and it can be determined whether it is due to insufficient communication link reliability or instruction execution reliability problems. Once the root cause of the low reliability is clarified, more specific reliability indicators can be further traced and determined. Through this process, a clear direction can be provided for the optimization of subsequent service instruction communication, and a quantitative basis can be provided for formulating optimization measures, thereby helping to further improve the reliability of service instruction communication.

[0049] In some embodiments, the sending device initiates a target application task, and the target application task corresponds to a first set of service instructions, where the first set of service instructions includes multiple independent service instructions; the method further includes: jointly statistically analyzing the communication execution reliability data of each service instruction to obtain the communication execution reliability data of the target application task.

[0050] Among them, the target application task can be initiated on the sending device and is a certain task that needs to be executed on the receiving device to achieve a specific purpose. The first set of service instructions can be a set composed of all the service instructions included in the target application task. Independence can mean that the success or failure of one service instruction does not affect the execution of other service instructions. Joint statistical analysis can be a process of analyzing and statistically processing the communication execution reliability data of multiple service instructions, aiming to obtain a comprehensive statistical result as the communication execution reliability data of the target application task.

[0051] In some embodiments, there are three modules A, B, and C on a remote sensing satellite, and there is no association between the parameters of the three modules. The target application task is to update the parameters of these three modules, and the first set of service instructions can include three independent service instructions: updating the parameters of module A, updating the parameters of module B, and updating the parameters of module C. It should be noted that each service instruction is independent of each other. Therefore, the communication reliability of each service instruction can be evaluated separately to obtain their respective communication execution reliability data. Since the target application task corresponds to three service instructions, and each service instruction needs to be executed to completion before the target application task can be considered completed, the communication execution reliability data of the target application task needs to be jointly statistically analyzed based on the communication execution reliability data of the three service instructions. For example, the weights of the three service instructions are 、 、 respectively, and the communication execution reliability data are P1, P2, and P3 respectively. The communication execution reliability data of the target application task can be: Among them, is the communication execution reliability data of the target application task.

[0052] In the above embodiments, the first set of service instructions corresponding to the target application task includes multiple independent instructions. By jointly statistically analyzing the communication execution reliability data of each service instruction to obtain the communication execution reliability data of the target application task, it can provide a strong quantitative basis for subsequent optimization and adjustment of the target application task.

[0053] In some embodiments, the communication execution reliability data of each service instruction is represented by a fuzzy probability; the communication execution reliability data of each service instruction is jointly statistically analyzed to obtain the communication execution reliability data of the target application task, including: multiplying the fuzzy probabilities of each service instruction to obtain the reliability fuzzy probability evaluation data of the target application task.

[0054] Among them, the fuzzy probability can be a probability value obtained by a fuzzy logic method, which is used to measure the reliability of the successful execution of each service instruction.

[0055] In some embodiments, the target application task is to take a photo of a certain range on the earth by a remote sensing satellite. The first service instruction set may include four independent service instructions: checking the camera status, taking a photo, saving the photo in the temporary storage space of the satellite, and transmitting the photo back to the sending device. The communication execution reliability data of each service instruction is represented by a fuzzy probability, which are 0.8, 0.6, 0.7, and 0.8 respectively. Multiply the fuzzy probabilities of each service instruction to obtain the reliability fuzzy probability evaluation data of the target application task, that is, multiply the above three data, and the result is 0.2688.

[0056] In the above embodiments, the reliability fuzzy probability evaluation data of the target application task is obtained by multiplying the fuzzy probabilities of each service instruction, which can provide a strong quantitative basis for the subsequent optimization and adjustment of the target application task.

[0057] In some embodiments, please refer to Figure 2 , the sending device initiates a target application task, and the target application task corresponds to a first service instruction set, and the first service instruction set includes a plurality of mutually independent service instructions; the service instruction corresponds to a priority; before the sending device sends a service instruction to the communication link, the method further includes: S410. Obtain the first attribute set of each service instruction in the target application task and write the first attribute set into the structured database.

[0058] Among them, the priority can be the processing priority order that should be given to each service instruction during the execution process. The first attribute set at least includes the identifier, log identifier, type, priority, instruction content, and execution status of the service instruction. The structured database can be a database that stores data in a structured manner, usually using a table form for data storage.

[0059] In some embodiments, the priority corresponding to the service instruction includes an emergency level, a high priority level, a medium priority level, and a low priority level. Exemplarily, please refer to Table 1.

[0060] Table 1 Example table of service instruction priorities In some embodiments, relevant attribute information of business instructions to be executed is stored in a structured database as the initial business instruction communication log, such as an oracle database. Further, after the business instructions are executed, relevant information on reliability evaluation is also updated to this database for monitoring and managing the communication process. Exemplarily, for each data table corresponding to a business instruction, in addition to storing the identification of the business instruction, log identification, type, priority, instruction content, and execution status, other fields can also be stored. Please refer to Table 2.

[0061] Table 2 Example Table of Structured Data for Business Instruction Communication S420. Obtain the second attribute set of each business instruction in the target application task and write the second attribute set into the cache database.

[0062] Among them, the second attribute set at least includes the identification of the business instruction, log identification, priority, destination terminal identification, instruction content, and preservation duration. The cache database can be a database that stores and accesses data quickly through memory and is usually used to improve the speed of data access.

[0063] In some embodiments, relevant attribute information of business instructions to be executed is stored in the cache database to enable quick reading of business instructions from the cache and improve the response speed in the communication system. The use of the cache database effectively reduces access latency and ensures that business instructions can be processed and executed in a timely manner. Exemplarily, the combination of the business instruction identification, priority, and destination terminal ID is saved as a key value in the cache database. For example, if the business instruction identification is 20, the priority value is 2, and the destination terminal ID is dev-1234, then the key value is "20,2,dev-1234". The data content corresponding to the key value can be in JSON format and can include the creation time, preservation duration, business instruction communication log identification, priority, and business instruction communication data.

[0064] In the above embodiments, before the sending device issues a business instruction to the communication link, the first attribute set of each business instruction in the target application task is written into the structured database to record the specific information and reliability evaluation information of each business instruction for subsequent traceability. At the same time, the second attribute set of each business instruction is written into the cache database to ensure that business instructions can be quickly read from the cache during the communication process, thereby improving the response speed of the communication system.

[0065] Please refer to Figure 3 , in some embodiments, the type of the business instruction corresponds to the priority; the method further includes: S510. When the type of the service instruction corresponds to the first priority, if the instruction response situation of the service instruction indicates that the service instruction is executed successfully, delete the corresponding service instruction from the cache database.

[0066] S520. When the type of the service instruction corresponds to the second priority, if the sending device receives the instruction response situation of the service instruction, delete the corresponding service instruction from the cache database.

[0067] Among them, the first priority is higher than the second priority. When processing instructions, service instructions with higher importance will be executed preferentially. The higher the priority of a service instruction, the stronger its urgency or the greater its impact. Therefore, more communication resources and processing capabilities will be allocated to ensure that it can be completed in time. The instruction response situation includes the reception situation of the response information and the service instruction execution result obtained by parsing the response information.

[0068] In some embodiments, the first service instruction set of a target application task includes several service instructions of the first priority and several service instructions of the second priority. After writing the first attribute set of each service instruction into the structured database and the second attribute set into the cache database, use a network performance detection tool to detect whether the network communication status is normal (for example, detect network connectivity, and whether the bit error rate, packet loss rate, link delay, and link jitter are lower than the preset thresholds). If the network status is normal, send the service instructions in the first service instruction set to the communication link asynchronously. Subsequently, detect the sending status of each service instruction; if the sending is successful, wait to receive the corresponding response information. In the case of receiving a response message, parse the response information to obtain whether the service instruction is executed successfully.

[0069] In some embodiments, if a service instruction of the first priority is executed successfully, delete the corresponding service instruction from the cache database. If the execution fails, read the corresponding service instruction from the cache database and send it to the communication link to execute again until the execution is successful.

[0070] In some embodiments, for a service instruction of the second priority, as long as the sending device receives the response information, regardless of whether it is executed successfully, the corresponding service instruction can be deleted from the cache database.

[0071] In some embodiments, before deleting a service instruction, it is necessary to check whether the relevant data of the execution result, status information, and reliability evaluation of the service instruction (such as evaluation data of bit error rate, packet loss rate, link delay situation, and link jitter situation, evaluation data of instruction response time and instruction execution success rate, communication link reliability data, instruction execution reliability data, and communication execution reliability data) have been written into the structured database to ensure that these data have been recorded for subsequent traceability.

[0072] In some embodiments, the first priority is further divided into an emergency level and a high priority level, and the second priority is further divided into a medium priority level and a low priority level. The cache database can also set the retention duration of service instructions, so as to further refine the execution policy of service instructions. Exemplarily, the retention duration of service instructions at the emergency level is permanent, and they can only be deleted after successful execution. The retention duration of service instructions at the high priority level is 30 minutes. If the service instructions at the first priority level fail to execute, they need to be re-executed. However, if they still fail to execute successfully after 30 minutes, they will be automatically deleted. The retention duration of service instructions at the medium priority level is 20 minutes. If the service instructions at the second priority level do not receive a response message, they need to be re-executed. However, if they still do not receive a response message after multiple executions within 20 minutes, the service instructions will be automatically deleted. The retention duration of service instructions at the low priority level is 10 minutes. If they do not receive a response message, they need to be re-executed. However, if they still do not receive a response message after multiple executions within 10 minutes, they will be automatically deleted.

[0073] Please refer to Figure 4 , in some embodiments, the type of service instruction corresponds to the priority; the service instruction to be sent to the communication link is determined by the following method: S610. Read the second set of service instructions from the cache database, and monitor the response information corresponding to the second set of service instructions to obtain the reception status and parsing result of the response information.

[0074] S620. Screen the second set of service instructions according to the reception status and parsing result to obtain a set of target instructions.

[0075] S630. Sort the service instructions in the set of target instructions according to the priority, and send the service instructions to the communication link according to the sorting result.

[0076] Among them, the second set of service instructions can be a set composed of service instructions that have not been deleted in the cache database of the sending device. These service instructions can belong to one target application task or multiple target application tasks. The set of target service instructions can be a set composed of service instructions that need to be resent.

[0077] In some embodiments, the sending device has a service instruction inspection timer. In each time period, the timer first reads the second set of service instructions from the cache database and listens for the reception status and parsing result of the response information. If the result of successful execution of the first-priority service instruction or the response information of the second-priority service instruction is monitored, the corresponding service instruction is screened out from the second set of service instructions, and the remaining service instructions form the target instruction set. Then, the service instructions in the target instruction set are sorted from high to low according to the priority, and are sent to their respective corresponding communication links asynchronously when the network communication status is normal.

[0078] In the above embodiment, by listening to the response information of the second set of service instructions and combining the reception status and parsing result to screen the instructions, the target instruction set is obtained. Then, the target instruction set is sorted according to the priority of the service instructions, and the instructions are sent to the communication link according to the sorting result. In this way, the reliability of the communication system can be improved, and it is ensured that important instructions are preferentially processed among multiple service instructions, thereby optimizing the resource utilization of the communication system and enhancing the overall reliability of the communication system.

[0079] Please refer to Figure 5 , in some embodiments, the communication execution reliability data of each service instruction is represented by a fuzzy probability; the link reliability of the communication link is evaluated according to the bit error rate, packet loss rate, link delay situation and link jitter situation, and the execution reliability is evaluated according to the instruction response situation, including: S710. When the value of the target index is less than the first threshold corresponding to the target index, determine that the fuzzy probability is equal to the first preset value.

[0080] S720. When the value of the target index is greater than or equal to the first threshold corresponding to the target index and less than the second threshold, perform a first type of calculation based on the value of the target index, the first threshold, the second threshold and the second preset value to obtain the corresponding fuzzy probability.

[0081] S730. When the value of the target index is greater than or equal to the second threshold corresponding to the target index and less than the third threshold, perform a second type of calculation based on the value of the target index, the second threshold and the third threshold to obtain the corresponding fuzzy probability.

[0082] S740. When the value of the target index is greater than or equal to the third threshold, determine that the fuzzy probability is equal to the third preset value.

[0083] Among them, the target metric can be any one of bit error rate, packet loss rate, link delay situation, link jitter situation, instruction response time, or instruction execution success rate. The first threshold can be the critical value when the reliability of the target metric reaches 100%. The first preset value can be 1. The second threshold can be the critical value when the reliability of the target metric reaches 50%. The second preset value can be 0.5. The third threshold can be the critical value when the complete reliability of the target metric is 0. The third preset value can be 0.

[0084] In some embodiments, the bit error rate (BER) is evaluated using fuzzy probability. First, simulate the bit error rates of the sending device, the receiving device, and the communication link between them to determine that the first threshold is , and the second threshold is , and the third threshold is . Therefore, when the BER is less than , the corresponding fuzzy probability is 1; when the BER is greater than or equal to , the corresponding fuzzy probability is 0. When the BER is greater than or equal to the first threshold and less than the second threshold, use the first type of calculation formula to calculate the fuzzy probability, where x = BER = number of error bits / total number of transmitted bits, , represent constants. When the BER is greater than or equal to the second threshold and less than the third threshold, use the second type of calculation formula to calculate the fuzzy probability, where = BER = number of error bits / total number of transmitted bits, , represent constants. In summary, the fuzzy probability evaluation of the bit error rate can use the following piecewise function: where = BER = number of error bits / total number of transmitted bits, represents the fuzzy probability of the bit error rate, , represent constants. Exemplarily, = -12, = -3, = -1.

[0085] Continue to simulate the packet loss rate, link delay situation, link jitter situation, instruction response time, or instruction execution success rate of the communication link respectively to obtain their first thresholds, second thresholds, and third thresholds, and then obtain their respective fuzzy probability piecewise functions.

[0086] The piecewise function for the fuzzy probability evaluation of the packet loss rate (PLR, Packet Loss Rate) is as follows: where x = PLR = number of lost data packets / total number of sent data packets, represents the fuzzy probability of the packet loss rate, and represent constants. Exemplarily, = -4, = -2, = -1.

[0087] The piecewise function for the fuzzy probability evaluation of the link latency situation (Lat, Latency) is as follows: where = Lat = reception time - transmission time, in ms, represents the fuzzy probability of the link latency situation, and and represent constants. Exemplarily, = 1, = 150, = 500.

[0088] The piecewise function for the fuzzy probability evaluation of the link jitter situation (Jit, Jitter) is as follows: where = Jit = standard deviation of the data packet arrival time, in ms, represents the fuzzy probability of the link jitter situation, and and represent constants. Exemplarily, = 1, = 100, = 300.

[0089] The piecewise function for the fuzzy probability evaluation of the instruction response time (Res, Response) is as follows: where = Res = 2Lat + execution duration of the instruction at the receiving end, in ms, represents the fuzzy probability of the instruction response time, and and represent constants. Exemplarily, = 150, =500, =1500。

[0090] The piecewise function for the fuzzy probability evaluation of the instruction execution success rate (Exe, execution) is: where x = 1 - Exe (Exe = the number of successful instruction execution operations / the total number of instruction execution operations), (x) represents the fuzzy probability of the instruction execution success rate, 、 、 represent constants. Exemplarily, =-3, =-2, =-1.

[0091] In some embodiments, the reliability evaluation model of the service instruction includes the fuzzy probability piecewise function of the target indicators (including bit error rate, packet loss rate, link delay situation, link jitter situation, instruction response time, or instruction execution success rate), the relationship between the communication link reliability data and the fuzzy probability of the target indicators (such as where, is the communication link reliability data, is the bit error rate evaluation data, is the packet loss rate evaluation data, is the link delay evaluation data, is the link jitter evaluation data, 、 、 、 are the influence degrees of the bit error rate, packet loss rate, link delay situation, and link jitter situation respectively), the relationship between the communication link reliability data and the fuzzy probability of the target indicators (such as where, is the instruction execution reliability data, is the instruction response time evaluation data, is the instruction execution success rate evaluation data, 、 are the influence degrees of the instruction response time and instruction execution success rate respectively), and the relationship between the communication execution reliability data and the communication link reliability data and between the communication link reliability data (such as where P is the communication execution reliability data of the service instruction, is the communication link reliability data, is the instruction execution reliability data, For communication link reliability data, and the degree of influence on instruction execution reliability data).

[0092] In some embodiments, when writing the first attribute set of each service instruction in the target application task into the structured database, the first threshold, the second threshold, the third threshold of the target metric, the degree of influence of the target metric on the communication link reliability ( , and ), the degree of influence of the target metric on the execution reliability of the service instruction ( and ), as well as the communication link reliability data and the degree of influence of the instruction execution reliability data on the communication reliability ( and ) are written together. Thus, these data and the value of the target metric can be input into the reliability evaluation model to obtain the communication reliability evaluation of the service instruction. For the data fields that need to be added to the structured data table, please refer to Table 3.

[0093] Table 3 Example Table of Service Instruction Communication Structured Data In the above embodiments, different fuzzy probability calculation methods are determined according to the range of the target metric value, so as to obtain a more accurate fuzzy probability of the target metric, providing accurate target metric evaluation data for the communication reliability evaluation.
