Description

Technical Field

[0001] The present invention relates to the technical field of switch communication systems, and in particular to a switch communication system with adaptive fault tolerance capability and an implementation method thereof. Background Art

[0002] With the rapid development of information technology, the importance of network communication in various fields has become increasingly prominent. As a key device in network communication, the reliability and stability of switches are crucial to ensure the normal operation of the network. However, in the actual network environment, switches face many challenges.

[0003] First, there is a possibility of failure of various components inside the switch. For example, the port may fail due to hardware damage, poor connection, etc., affecting the normal transmission of data. At the same time, the communication link may also cause abnormal data packet transmission due to various external factors, such as physical line damage, electromagnetic interference, etc.

[0004] Traditional switches are often not smart and timely enough in fault detection, and cannot accurately and quickly locate the fault type and location. When a fault occurs, manual intervention is usually required for troubleshooting and repair, which is not only time-consuming, but may also cause network communication interruption for a long time, affecting the normal development of business.

[0005] In terms of fault tolerance, existing switch solutions have certain limitations. When a fault occurs, the working mode cannot be adjusted quickly and effectively to ensure the continuity of communication. For example, when a port fails, the lack of intelligent path adjustment strategy may cause data transmission to be blocked. Moreover, the switching of redundant links is not smooth enough, which easily causes problems such as packet loss.

[0006] In terms of performance optimization, traditional switches cannot be dynamically adjusted according to real-time system status and fault tolerance mode. For example, they cannot flexibly adjust parameters such as packet cache size, data transmission rate, and processor operating frequency according to factors such as load conditions and network quality, resulting in performance problems such as excessive communication delay and insufficient throughput under different working conditions, which cannot meet the growing demand for network communication quality.

[0007] In summary, the existing switch communication system has many deficiencies in fault detection, fault tolerance and performance optimization. There is an urgent need for a switch communication system with adaptive fault tolerance and its implementation method to solve these problems in order to improve the reliability, stability and performance of network communication. Summary of the invention

[0008] The present invention provides a switch communication system with adaptive fault tolerance capability and an implementation method thereof to solve the problems mentioned in the above-mentioned prior art.

[0009] In order to achieve the above object, the present invention adopts the following technical solution: a switch communication system with adaptive fault tolerance capability, comprising:

[0010] The fault detection module is used to monitor the operating status of the components and communication links inside the switch in real time. The specific monitoring port status is measured by the variable P s Indicates that its value is 0 for normal and 1 for abnormal. The data packet transmission status is expressed by the number of data packets transmitted per second D p The chip operating temperature is represented by the variable T c Indicates that the unit is Celsius. It determines whether there is a fault by periodically sending detection signals and receiving feedback. If an abnormal situation is detected, the alarm mechanism is triggered and the fault information is sent to the fault diagnosis module. The detection signal frequency is based on the load of the switch. p The importance is dynamically adjusted, and the adjustment formula is:

[0011] When L p >80% or in a critical business scenario, the system presets the critical business flag B k , B k =1 indicates critical business, the detection signal frequency f d Adjust to 10 times per second; when L p ≤80% and B k =0, adjust f d 5 times per second to reduce system resource usage;

[0012] The fault diagnosis module is connected to the fault detection module. After receiving the fault information sent by the fault detection module, it accurately locates the fault type and fault location through the intelligent diagnosis algorithm. The diagnosis formula is: F = αP s +βT c +γD p +δH, where F represents the fault diagnosis result, H represents the historical fault data, and H n represents the number of historical faults, α, β, γ, and δ are weight coefficients, which are 0.3, 0.2, 0.4, and 0.1 respectively;

[0013] The adaptive fault-tolerant module is connected to the fault diagnosis module. After the fault diagnosis module determines the fault type and location, the module automatically adjusts the working mode of the switch according to the preset fault-tolerant strategy to ensure the continuity of communication. The fault-tolerant strategy includes redundant link switching, data packet retransmission mechanism and data cache strategy. When some ports fail, the module automatically adjusts the data transmission path using the following formula: Assume that the switch has n ports, and the port set is P = {P 1 , P 2 , ..., P n}, under normal circumstances, data from the source port P sTransfer to destination port P d , when port P i When a fault occurs, i∈{1, 2, ..., n}, if there is a backup port P j (j∈{1, 2, ..., n} and j≠i, satisfying the distance condition: spare port P j To the destination port P d Network distance Less than the threshold d th , set to 10 meters; performance conditions: spare port P j Current available bandwidth Greater than threshold b th , set to 100Mbps, then the data transmission path is changed from P s →P i →P d Adjust to P s →P j →P d .

[0014] The performance optimization module is connected to the adaptive fault tolerance module, which continuously monitors the performance of the switch communication system in the fault tolerance mode, including the communication delay time T d , in milliseconds, throughput, the amount of data transmitted per second T h It is expressed in Mbps, and its optimization formula is: O = ∈T d +ζT h +ηT+θR, where O represents the performance optimization result, T is the current fault tolerance mode parameter, 0 represents the normal mode, 1 represents the fault tolerance mode, R is the resource utilization parameter, R p It indicates the proportion of used resources to total resources, ∈, ζ, η, θ are weight coefficients, which take values ​​of 0.2, 0.4, 0.2, and 0.2 respectively.

[0015] Preferably, the fault diagnosis module adopts a decision tree algorithm or a neural network algorithm in machine learning to improve the accuracy and speed of fault diagnosis by learning a large amount of training data.

[0016] Preferably, the redundant link switching strategy of the adaptive fault-tolerant module adopts the Rapid Spanning Tree Protocol RSTP or the Multiple Spanning Tree Protocol MSTP, which is used to quickly switch to the backup link when a link fails, thereby reducing the communication interruption time.

[0017] Preferably, the performance optimization module dynamically adjusts system parameters including:

[0018] Adjust the packet cache size: Set the initial cache size to C s , according to the current load condition L p Adjustment, when L p >60%, the cache size is adjusted to 1.5Cs , when L p When ≤60%, the cache size is adjusted to 0.8C s ;

[0019] Data transmission rate: Assume the initial transmission rate is V s , according to the network quality Q n Adjust, when Q n When good, V s Increase by 10%, when Q n In the worst case, V s 10% reduction;

[0020] Processor operating frequency: Set the initial frequency to F s , according to the system load and temperature conditions, when L p >70% and T c >50℃, reduce by 20%, when L p ≤70℃ and T c When ≤50℃, increase by 10% to adapt to different fault tolerance modes and system load conditions.

[0022] S1: The fault detection module monitors the operating status of the components and communication links inside the switch in real time;

[0023] S2: When the fault detection module detects an abnormal situation, it sends the fault information to the fault diagnosis module, and uses the intelligent diagnosis algorithm to determine the fault type and location. After determining the fault type and location, the fault diagnosis module records the diagnosis results in the fault log for subsequent analysis and improvement of the fault diagnosis algorithm;

[0024] S3: According to the fault diagnosis results, the adaptive fault-tolerant module automatically adjusts the working mode of the switch to ensure communication continuity. When performing redundant link switching, the adaptive fault-tolerant module uses smooth transition technology to avoid data packet loss and communication interruption caused by link switching;

[0025] S4: The performance optimization module continuously monitors the performance of the switch communication system in fault-tolerant mode, and improves system performance and stability by dynamically adjusting system parameters and optimization algorithms. When dynamically adjusting system parameters, the performance optimization module uses simulated annealing algorithm or particle swarm optimization algorithm to find the optimal parameter combination to achieve the best performance optimization effect;

[0026] S5: When the system does not detect a fault for a period of time, it automatically returns to normal working mode and evaluates and records the previous fault-tolerant operations to analyze whether there are areas for improvement. The evaluation indicators include the fault-tolerant time T f , data transmission recovery speed V r , if T f >10 seconds or V r If the speed is less than 50Mbps / s, it is marked as requiring further optimization;

[0027] S6: Perform comprehensive performance testing and fault simulation on the switch communication system to verify the system's adaptive fault tolerance and performance optimization effect, and adjust system parameters and optimization strategies based on the test results. Performance test indicators include average communication delay and maximum throughput.

A summary analysis is conducted every month to timely identify potential problems and improvement directions;

[0029] S8: Based on the data analysis results in the system operation report, update and optimize the system's fault detection frequency, fault diagnosis algorithm, fault tolerance strategy, and performance optimization algorithm to ensure that the system always maintains good adaptive fault tolerance and performance;

[0030] S9: When the switch communication system undergoes hardware upgrades or software updates, the parameters of the relevant modules are automatically reconfigured and optimized to adapt to the new system environment. At the same time, the updated system is fully tested and verified to ensure system stability and reliability.

[0031] S10: Establish a real-time interaction mechanism with users. When the system fails or performs important operations, notifications and prompts are sent to users. Users can view the system's operating status, fault details, and optimization suggestions through the interactive interface, and personalize system parameters according to their own needs.

[0032] Preferably, the present invention further discloses a device of a switch communication system with adaptive fault tolerance capability, comprising:

[0033] A processor, configured to execute the above-mentioned implementation method of the switch communication system with adaptive fault tolerance capability;

[0034] A memory, used to store data and program codes required by the processor to execute the above method;

[0037] Preferably, the present invention further discloses a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, a switch communication system with adaptive fault tolerance capability is implemented.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. Intelligent fault detection and rapid positioning:

[0040] By real-time monitoring of the operating status of the components and communication links inside the switch, and using precise detection signals and intelligent diagnostic algorithms, faults can be detected quickly and accurately and the fault type and location can be located. For example, when the port status is abnormal or the chip operating temperature is too high, the problem can be discovered in time to prevent the fault from further expanding and reduce the impact on network communications.

[0041] The detection signal frequency is dynamically adjusted according to the load conditions and importance. The detection frequency is increased in high-load or critical business scenarios to ensure timely detection of faults. The detection frequency is appropriately reduced in low-load scenarios to reduce system resource usage and improve the overall efficiency of the system.

[0042] 2. Adaptive fault tolerance ensures communication continuity:

[0043] When a fault occurs, the adaptive fault-tolerance module can automatically adjust the switch's operating mode according to the preset fault-tolerance strategy. For example, when some ports fail, the precise path adjustment formula can quickly find a backup port that meets the conditions, automatically adjust the data transmission path, realize traffic redistribution, and ensure communication continuity.

[0044] Adopt redundant link switching strategies, such as Rapid Spanning Tree Protocol (RSTP) or Multiple Spanning Tree Protocol (MSTP), which can quickly switch to the backup link when a link fails, reduce communication interruption time, and improve network reliability.

[0045] 3. Performance optimization improves system stability:

[0046] The performance optimization module continuously monitors the performance of the switch communication system in fault-tolerant mode. Through specific optimization formulas and dynamic adjustment of system parameters, such as adjusting the packet cache size according to load conditions, adjusting the data transmission rate according to network quality, and adjusting the processor operating frequency according to system load and temperature conditions, it can further improve the system's performance and stability.

[0047] Use simulated annealing algorithm or particle swarm optimization algorithm to find the optimal parameter combination, achieve the best performance optimization effect, reduce communication delay, improve throughput, and meet the requirements of network communication quality in different application scenarios.

[0048] 4. System overall optimization and user interaction:

[0049] By automatically restoring the system to normal working mode when no fault is detected for a period of time, evaluating and recording it, as well as regular performance testing and fault simulation, the adaptive fault tolerance and performance optimization effect of the system can be continuously improved. For example, relevant parameters can be adjusted according to evaluation indicators and test results to keep the system in good operating condition.

[0050] Establish a real-time interaction mechanism with users, send notifications and prompts to users in a timely manner, so that users can understand the system's operating status, fault details, optimization suggestions, etc. in real time, and can personalize some system parameters according to their own needs, thereby improving users' sense of control over the system and usage experience.
