Description

Technical Field

[0001] The present invention relates to a passive optical network (PON) technology in optical fiber communication technology, and in particular to a monitoring and control technology of an optical network unit (ONU). Background Art

[0002] With the continuous advancement of optical fiber communication technology, passive optical network (PON) technology has become the mainstream technology of modern broadband access networks due to its high efficiency and economic characteristics. The PON system transmits signals to multiple user optical network units (ONUs) through one optical fiber and multiple passive optical splitters, realizing long-distance and large-capacity information transmission. However, in practical applications, the stability and reliability of ONUs still face many challenges.

[0003] On the one hand, hardware failure is one of the common problems of ONU equipment. Since ONU equipment operates in a complex and changing environment for a long time, its hardware components may fail due to aging, wear or external interference, resulting in loss of signal (LOS) or reduced transmission quality. If such failures are not discovered and handled in time, they may cause network interruption and seriously affect user experience.

[0004] On the other hand, channel degradation is also an important factor affecting the stability and reliability of ONU equipment. In the PON system, the signal may be affected by factors such as attenuation, interference and noise during transmission, resulting in a decrease in channel quality. If the channel degrades to a certain extent, it will seriously affect the signal transmission quality and network stability.

[0005] In addition, with the continuous development of network technology and the increasing demand of users, higher requirements are placed on the performance and stability of ONU. Traditional fault monitoring and recovery methods often have problems such as slow response speed and low accuracy, which cannot meet the requirements of modern networks for high reliability and high availability. Summary of the invention

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Figure 1 The schematic diagram of the integrated monitoring system of the optical network unit in the present invention;

[0037] Figure 2 The flowchart of comprehensive monitoring of optical network units in an example of the present invention. DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0039] In order to solve the problem of stability and reliability of ONU equipment in PON system, the present invention provides a comprehensive monitoring solution for optical network unit. The comprehensive monitoring solution is based on real-time and comprehensive monitoring of the overall status of ONU equipment, and cooperates with intelligent switching and rapid recovery monitoring mechanism to ensure the continuity and stability of network connection of ONU equipment, thereby significantly improving the performance and user experience of PON network.

[0040] Based on this, the present invention provides a comprehensive monitoring system solution for an optical network unit, such as Figure 1 As shown, the integrated monitoring system 100 is mainly composed of a hardware signal loss monitoring module 110, a channel degradation monitoring module 120, a registration status monitoring module 130 and an automatic switching module 140 that cooperate with each other.

[0041] The hardware signal loss monitoring module 110 is configured to monitor the hardware signal loss status of the ONU device in real time by means of hardware interruption, and when signal loss is detected, immediately trigger a hardware fault warning signal through hardware interruption.

[0042] The channel degradation monitoring module 120 is configured to perform low-level detection of channel quality parameters, evaluate the channel status in real time, and trigger the generation of a channel degradation warning signal when the channel quality is lower than a preset threshold;

[0043] The registration status monitoring module 130 is configured to periodically send a heartbeat signal to the ONU device and receive a response to confirm the online status of the ONU device.

[0044] The automatic switching module 140 is configured to maintain real-time data interaction with the hardware signal loss monitoring module 110, the channel degradation monitoring module 120, and the registration status monitoring module 130, and can receive in real time the hardware fault early warning signal, channel degradation warning signal and heartbeat signal detection results generated by the hardware signal loss monitoring module 110, the channel degradation monitoring module 120, and the registration status monitoring module 130, comprehensively judge the fault type and severity, and select and execute the optimal switching path and recovery strategy through the interrupt notification processing mechanism.

[0045] Based on the comprehensive monitoring system 100 of the optical network unit formed by the above solution, its implementation scheme and corresponding technical features are specifically described below.

[0046] In the integrated monitoring system 100 of the optical network unit, a hardware signal loss monitoring module 110 is provided to monitor the hardware signal loss (LOS) status of the ONU device in real time through a hardware interruption mode.

[0047] As a further explanation, the hardware signal loss monitoring module 110 is implemented by configuring a hardware signal detection circuit to monitor the hardware signal status. The hardware signal detection circuit is directly connected to the hardware signal loss detection pin of the ONU device.

[0048] Specifically, the hardware signal detection circuit is configured with a low-latency signal detection circuit unit and a high-sensitivity signal recognition circuit unit. The entire hardware signal detection circuit has high-speed response capability and high stability. It can quickly and accurately detect abnormal situations at the moment of signal loss, and can effectively distinguish normal signal fluctuations from real signal loss events in complex network environments.

[0049] On this basis, the hardware signal detection circuit is also configured with a hardware interrupt trigger mechanism, which can trigger a hardware fault warning signal when signal loss is detected.

[0050] Accordingly, the hardware signal loss monitoring module 110 can realize real-time monitoring of the hardware signal status of the ONU device based on the configured hardware signal detection circuit. Once the signal loss is detected, the hardware fault warning signal is immediately triggered through the hardware interrupt, and the warning can be triggered quickly so that the system can take timely response measures, such as switching backup links, restarting equipment or notifying maintenance personnel, thereby ensuring the reliability and stability of the network system.

[0051] The hardware signal loss monitoring solution adopted by the hardware signal loss monitoring module 110 has higher real-time performance and response speed than the traditional software polling method, and can achieve rapid response and processing of hardware failures.

[0052] Based on the hardware fault monitoring, the integrated monitoring system 100 further provides a channel degradation monitoring module 120, thereby synchronously realizing the bottom-level detection of channel quality parameters and evaluating the channel status in real time.

[0053] As a further explanation, the channel degradation monitoring module 120 is provided with a bit error rate detection unit and a signal-to-noise ratio detection unit, wherein the bit error rate detection unit is configured to detect the bit error rate of the channel, and the signal-to-noise ratio detection unit is configured to detect the signal-to-noise ratio of the channel; on this basis, the channel degradation monitoring module 120 also compares the bit error rate and signal-to-noise ratio values ​​of the detection channel synchronously detected by the bit error rate detection unit and the signal-to-noise ratio detection unit with the corresponding preset thresholds to determine the current channel quality, and when the channel quality is lower than the preset threshold, a channel degradation warning is triggered.

[0054] Furthermore, the bit error rate detection unit in the channel degradation monitoring module 120 is provided with a symbol recognition module, a symbol counting unit and a bit error rate calculation module.

[0055] Among them, the code element recognition module is configured to perform real-time analysis on the code elements in the data stream and quickly identify bit error events in the data stream; the code element counting unit is configured to interact with the code element recognition module data and count the number of code elements actually transmitted in the data stream according to the recognition result of the code element recognition module; the bit error rate calculation module is configured to interact with the code element counting unit data and obtain the number of code elements actually transmitted as determined by the code element counting unit, and compare and calculate the number of code elements actually transmitted with the theoretical value corresponding to the code elements in the data stream, thereby calculating the bit error rate.

[0056] The signal-to-noise ratio detection unit in the channel degradation monitoring module 120 specifically measures the signal power and the noise power, and evaluates the communication quality of the channel through the ratio of the two.

[0057] The signal-to-noise ratio detection unit is specifically provided with a signal receiving module, a power measuring module, and an adaptive calibration module. The signal receiving module is configured to obtain a corresponding data signal, and the power measuring module is configured to interact with the signal receiving module for data measurement, and is used to measure the power of the signal received by the signal receiving module, and can accurately capture weak signal changes and effectively distinguish between signals and noise; the adaptive calibration module is configured to interact with the signal receiving module and the power measuring module for data, and can perform deviation calibration on the results measured by the signal receiving module and the power measuring module according to different network environments and device characteristics.

[0058] The channel degradation monitoring module 120 can process and analyze the received signal in real time through the cooperation between the bit error rate detection unit and the signal-to-noise ratio detection unit, thereby ensuring the accuracy and reliability of the detection result, and accurately calculating the bit error rate and the signal-to-noise ratio.

[0059] Furthermore, the channel degradation monitoring module 120 is also provided with an interrupt trigger unit, which is configured to interact with the bit error rate detection unit and the signal-to-noise ratio detection unit data, and can trigger a channel degradation warning when the channel quality is lower than a preset threshold.

[0060] The interrupt trigger unit is configured to trigger a channel degradation warning by a soft interrupt, that is, when the code rate detection unit or the signal-to-noise ratio detection unit detects that the channel quality drops below a preset threshold, a channel degradation warning is triggered by a soft interrupt.

[0061] The soft interrupt method here can transmit emergency information to the processor or control center without affecting the normal operation of the system.

[0062] As a further explanation, the interrupt triggering unit uses the interrupt controller and the interrupt service program to cooperate with each other to implement a soft interrupt mode to trigger the channel degradation warning.

[0063] The interrupt controller is configured to receive interrupt requests from the bit rate detection unit and the signal-to-noise ratio detection unit, and sort and process them according to priority. The interrupt service program is configured to respond to the interrupt request and execute corresponding processing logic, such as recording error information, sending a warning signal, or triggering a system recovery mechanism.

[0064] In this way, the interrupt trigger unit can quickly issue a warning when the channel quality deteriorates, providing timely protection and recovery capabilities for the system.

[0065] The channel degradation monitoring module 120 formed based on the above solution can timely discover channel quality problems and provide early warning information to the administrator so that timely measures can be taken for intervention and optimization.

[0066] In order to realize comprehensive monitoring of the ONU device status, the integrated monitoring system 100 further provides a registration status monitoring module 130 based on the above solution, thereby performing real-time monitoring of the online status and registration status of the ONU device.

[0067] As a further explanation, the registration status monitoring module 130 can confirm the online status of the device by periodically sending a heartbeat signal to the ONU device and receiving a response.

[0068] As a further example, when the online status of the ONU device is monitored in real time, the registration status monitoring module 130 preferably sets the sending period of the heartbeat signal according to the network environment and the performance of the ONU device, thereby ensuring that the device offline situation can be discovered in time without causing excessive burden on the network. Furthermore, the format and content of the heartbeat signal are standardized so that the ONU device can correctly identify and respond. Finally, for the situation where a response is not received within the specified time, a corresponding alarm mechanism is further set so that the management personnel are notified in time for processing.

[0069] As a further explanation, the registration status monitoring module 130 synchronously monitors the registration status change notification of the ONU device and immediately notifies the system when the status changes.

[0070] As a further example, when the registration status monitoring module 130 synchronously monitors the registration status of the ONU device, the ONU device is configured to actively send a notification to the registration status monitoring module when the status changes. The notification should include specific information about the status change, such as from online to offline, or from registered to unregistered, etc.; furthermore, the registration status monitoring module 130 is configured to receive and process a large number of status change notifications in real time to ensure that the system can respond quickly to status changes.

[0071] In this way, the registration status monitoring module 130 can grasp the operating status of the ONU device (such as online status and registration status) in real time, and can promptly discover and handle abnormal situations.

[0072] Based on the above solution, the integrated monitoring system 100 further sets an automatic switching mode 140 to implement fast switching paths and status recovery of ONU devices based on an intelligent switching mechanism and an interrupt notification processing mechanism to ensure the continuity and stability of network connections.

[0073] As a further explanation, the preset intelligent switching mechanism in the automatic switching module 140 is designed to receive and comprehensively analyze various signals from the hardware signal loss monitoring module 110, the channel degradation monitoring module 120, and the registration status monitoring module 130, including fault warning signals, channel degradation warning signals and heartbeat signal detection results, and select and execute the optimal switching path and recovery strategy based on the analysis and judgment results.

[0074] Specifically, the implementation scheme of the automatic switching module 140 receiving and comprehensively analyzing various signals from the hardware signal loss monitoring module 110, the channel degradation monitoring module 120, and the registration status monitoring module 130 based on a preset intelligent switching mechanism mainly includes a comprehensive analysis and judgment stage and a switching path and recovery strategy selection stage.

[0075] In the comprehensive analysis and judgment stage, the automatic switching module 140 receives and comprehensively analyzes various signals from the hardware signal loss monitoring module 110, the channel degradation monitoring module 120, and the registration status monitoring module 130, including the fault warning signal, the channel degradation warning signal, and the heartbeat signal detection result. The corresponding process is as follows:

[0076] First, the automatic switching module 140 receives signals sent from each monitoring module based on a preset intelligent switching mechanism, and performs preliminary classification according to a preset priority order. For example, the fault warning signal sent by the hardware signal loss monitoring module 110 is preferably set to have the highest priority, because signal loss often means direct communication interruption or equipment failure.

[0077] Next, the automatic switching module 140 analyzes the channel degradation warning signal provided by the channel degradation monitoring module 120 to evaluate the current quality and degradation trend of the channel. For example, key parameters such as signal-to-noise ratio and bit error rate can be calculated and analyzed and compared with preset thresholds to determine whether the channel has approached or reached an unacceptable level.

[0078] At the same time, the automatic switching module 140 synchronously analyzes the heartbeat signal detection result of the registration status monitoring module 130, and evaluates the health of the current network status by analyzing the continuity and stability of the heartbeat signal. As an example, the automatic switching module 140 can compare the time difference between sending and receiving the heartbeat signal and the response status of the ONU device, and the algorithm can infer the online status and registration status of the device, thereby indirectly reflecting the health status of the network.

[0079] Next, the automatic switching module 140 performs comprehensive analysis and judgment based on the analysis results of the data signal sent by the monitoring module. Specifically, for the analysis result information of the above three types of signals (such as the urgency of the fault warning, the trend of channel degradation, and the abnormal frequency of the heartbeat signal), weighted scoring or fuzzy logic and other methods are used according to the preset weights to perform weighted processing on each analysis and detection result, thereby quantitatively evaluating the fault type and severity to form a comprehensive evaluation value.

[0080] As a further explanation, the comprehensive analysis and judgment process specifically introduces parameters such as the directness of the fault, the scope of impact, the duration, and historical data to ensure the accuracy and reliability of the judgment result.

[0081] Finally, the automatic switching module 140 determines whether to trigger the fault recovery mechanism based on the comprehensive evaluation result. If the comprehensive evaluation value exceeds the preset warning line, it is determined that a switching operation needs to be performed. The switching operation here includes switching to a backup channel, restarting the affected device, or notifying the management staff for manual intervention.

[0082] After the automatic switching module 140 determines the type and severity of the fault through the comprehensive analysis and judgment stage, it immediately enters the switching path and recovery strategy selection stage based on the intelligent switching mechanism. In this stage, based on the comprehensive judgment results and based on the preset decision rules and switching strategy library, it automatically selects and executes the optimal switching path and recovery strategy.

[0083] In the specific implementation of this stage, it is preferred to introduce factors such as the current network topology, the availability of backup resources, the scope of the fault impact, and the expected recovery time. The corresponding implementation process is as follows:

[0084] First, the automatic switching module 140 will preliminarily screen possible switching paths and recovery strategies according to the fault type. For example, for a hardware fault, the automatic switching module 140 will give priority to switching to backup hardware or backup paths;

[0085] For channel degradation, the automatic switching module 140 preferably attempts to adjust channel parameters, switch to other channels, or enable a channel redundancy mechanism;

[0086] If the device registration status is abnormal, the automatic switching module 140 preferably attempts to re-register the device or restart related services.

[0087] Next, the automatic switching module 140 further evaluates and optimizes the selected switching paths and recovery strategies. For example, the evaluation and optimization implementation here includes calculating the implementation cost of each strategy, the impact on network performance, and the expected recovery effect, etc. By comparing the advantages and disadvantages of different strategies, the algorithm can select the optimal switching path and recovery strategy.

[0088] Finally, the automatic switching module 140 immediately performs corresponding switching and recovery operations according to the determined optimal strategy. As an example, the switching and recovery operations here include sending switching instructions to related devices, adjusting network configuration, restarting affected devices, etc.

[0089] As a further explanation, when the automatic switching module 140 performs the corresponding switching and recovery operations, it will perform a pre-switching check before executing the switch to ensure that the switching operation will not introduce new risks or cause service interruption; after confirming that it is correct, it will automatically execute the switching command and monitor the status of the switching and recovery process in real time to ensure the successful execution of the operation. If the switching does not achieve the expected effect, the automatic switching module 140 can automatically try other recovery strategies or restore the original state according to the preset fallback mechanism to ensure the continuity and reliability of the network service. Throughout the process, the automatic switching module 140 also continuously collects and analyzes new data so that the strategy can be adjusted and optimized when necessary.

[0090] The automatic switching module 140 can quickly and accurately respond to various network failures and minimize the impact of network failures on users while ensuring the continuity and stability of network services when implementing rapid switching paths and status recovery for ONU devices based on a preset intelligent switching mechanism.

[0091] As a further explanation, the interruption notification processing mechanism preset in the automatic switching module 140 is intended to achieve rapid response and efficient processing, further ensuring the continuity and stability of the network connection.

[0092] Furthermore, based on the interruption notification processing mechanism, the automatic switching module 140 can immediately trigger an interruption notification process once a network failure or potential interruption risk is detected. The interruption notification process includes sending an interruption notification to relevant system components, management personnel or backup resources. The notification content includes specific information about the failure, the scope of impact, and recommended countermeasures, etc., thereby further ensuring the continuity and stability of the network connection.

[0093] As a further example, when the automatic switching module 140 achieves rapid response and efficient processing based on the interrupt notification processing mechanism, the interrupt notification is sent using a high-priority, low-latency communication protocol to ensure that the notification can be quickly conveyed to the relevant parties, which helps to shorten the time difference between fault discovery and response and improve overall processing efficiency.

[0094] Secondly, the interrupt notification processing mechanism also incorporates automation and intelligent mechanisms. For example, for certain predictable fault types, the automatic switching module 140 can automatically trigger a predefined recovery strategy to achieve rapid recovery of the fault without manual intervention. In addition, the automatic switching module 140 can also intelligently adjust and optimize the recovery strategy based on historical data and real-time monitoring information to improve recovery effect and efficiency.

[0095] Finally, the interruption notification processing mechanism is also equipped with a corresponding monitoring and feedback mechanism to ensure the continuity and stability of the network connection. Based on the interruption notification processing mechanism, the automatic switching module 140 can timely discover and correct potential problems by real-time monitoring of network status, recovery progress, user feedback and other information to ensure the smooth progress of the recovery process. At the same time, the automatic switching module 140 will also collect and analyze fault data to provide useful reference and reference in future network operation and maintenance.

[0096] Based on a preset interrupt notification processing mechanism, the automatic switching module 140 achieves rapid response and efficient processing by adopting high-priority communication protocols, incorporating automation and intelligent elements, and equipping a complete monitoring and feedback mechanism, thereby further ensuring the continuity and stability of the network connection.

[0097] The integrated monitoring system 100 further provides a MAC synchronization module 150 based on the above solution. The MAC synchronization module 150 is configured to maintain real-time data interaction with the automatic switching module 140, and can synchronize the corresponding MAC address when the automatic switching module executes the corresponding switching path and recovery strategy.

[0098] As a further explanation, the MAC synchronization module 150 is configured to first lock all user MAC address information under the current PON port after obtaining the notification sent by the automatic switching module 140 when detecting a PON port failure and deciding to perform a switching operation, including but not limited to the user's MAC address, corresponding VLAN tag, service type, etc.; then, the MAC synchronization module 150 will synchronize these MAC address information to the new PON port according to the switching path information provided by the automatic switching module 140. In this synchronization process, the MAC synchronization module 150 will ensure the integrity and accuracy of all MAC address information to avoid service interruption or performance degradation due to information loss or error.

[0099] As a further supplementary explanation, when the MAC synchronization module 150 is implemented, it can dynamically adjust the synchronization strategy according to the actual situation of the network and the needs of users to optimize network performance and resource utilization. For example, during peak hours, the module can prioritize the synchronization of MAC address information of high-priority users to ensure the continuity and stability of key services. The MAC synchronization module 150 also preferably adopts an efficient data synchronization algorithm and an optimized communication protocol to ensure that the MAC address information can be quickly and accurately synchronized between the new and old PON ports.

[0100] Such a MAC synchronization module 150, when cooperating with the automatic switching module 140, can synchronously perform MAC synchronization when the automatic switching module 140 switches the PON port. As an example, when a PON port (e.g., the main PON port) of a dual-PON port ONU device fails or requires maintenance, the automatic switching module 140 in the system can quickly control the ONU device to switch to another PON port (e.g., the standby PON port) to continue to provide network services; during the switching process, in order to ensure the continuity and stability of network communication, the MAC synchronization module 150 can synchronize the MAC address to the new PON port to further improve the stability and reliability of the network.

[0101] As a further explanation, the integrated monitoring system 100 may further include a network traffic monitoring module, a security authentication module and a fault log recording module as needed, thereby realizing functions such as network traffic monitoring, security authentication and fault log recording, and providing comprehensive support for network management and maintenance.

[0102] The comprehensive monitoring system of the optical network unit formed based on the above scheme can be run in the corresponding ONU device (such as dual-PON port ONU device) when applied, and can monitor the status of the ONU device in real time and in advance during the operation of the ONU device. Combined with the intelligent switching and rapid recovery monitoring mechanism, it can ensure the continuity and stability of the network connection of the ONU device.

[0103] The ONU device described here may be a dual-PON port ONU device, but is not limited thereto.

[0104] The process of the integrated monitoring system of the optical network unit to realize the integrated monitoring of the ONU equipment is as follows:

[0105] Hardware signal loss status monitoring:

[0106] The system uses hardware interruption to monitor the hardware signal loss (LOS) status of ONU equipment in real time. Once the signal loss is detected, the hardware fault warning signal is immediately triggered through hardware interruption, realizing a rapid response to hardware faults.

[0107] Channel degradation monitoring:

[0108] By performing low-level detection on channel quality parameters (such as bit error rate and signal-to-noise ratio), the system can evaluate the channel status in real time. When the channel quality is lower than the preset threshold, a channel degradation warning is triggered through a soft interrupt to ensure that the administrator can quickly pay attention to the channel health status.

[0109] Registration status monitoring;

[0110] Regularly send heartbeat signals to ONU devices and receive responses to confirm the online status of the device; at the same time, based on the registration status change notification mechanism, the registration status of the ONU device is monitored in real time. When the registration status of the ONU device changes, the system will receive a notification immediately, thereby achieving more comprehensive monitoring of the device status;

[0111] Automatic switching:

[0112] Based on the monitored fault warnings, channel degradation warnings and heartbeat signal detection results, the fault type and severity are comprehensively judged. Through the interruption notification processing mechanism, the system can more efficiently and quickly select and execute the optimal switching path and recovery strategy to ensure the continuity and stability of network connections and reduce business interruption time.

[0113] As a further explanation, when the scheme performs comprehensive monitoring on the ONU device, the hardware signal loss status monitoring step, the channel degradation monitoring step and the registration status monitoring step can be executed simultaneously or sequentially according to a timing rule.

[0114] As a further explanation, when the ONU device is comprehensively monitored in this solution, MAC synchronization is also performed synchronously in the automatic switching step, that is, when the corresponding switching path and recovery strategy are executed in the automatic switching step, the corresponding MAC synchronization is performed synchronously.

[0115] It can be seen from the above that the comprehensive monitoring solution for optical network units provided by the present invention can realize comprehensive monitoring, intelligent switching and rapid recovery of ONU devices, thereby improving the stability and reliability of the PON network.

[0116] At the same time, a large number of experimental results show that the comprehensive monitoring solution of the optical network unit provided by the present invention can effectively reduce the probability of network interruption and improve the network recovery speed and reliability. The implementation of the solution of the present invention will significantly improve the performance and user experience of the PON network, and has important practical value and social benefits.

[0117] The comprehensive monitoring solution for an optical network unit provided by the present invention is further described below through corresponding application examples.

[0118] In this example, for the dual-PON port ONU device, a corresponding comprehensive monitoring system is constructed based on the comprehensive monitoring solution of the optical network unit provided by the present invention, and runs in the dual-PON port ONU device.

[0119] See also Figure 2 Therefore, the specific implementation steps for comprehensive monitoring of dual-PON port ONU equipment are as follows:

[0120] First, at the initial stage of system startup, the initialize_system function is executed, which is responsible for setting system parameters, initializing hardware interfaces, and configuring monitoring thresholds. These steps are necessary preparations for system startup to ensure that subsequent monitoring and switching operations can proceed smoothly.

[0121] void initialize_system(){

[0122] / / Set system parameters

[0123] set_system_parameters();

[0124] / / Initialize the hardware interface

[0125] init_hardware_interfaces();

[0126] / / Configure monitoring thresholds

[0127] configure_monitoring_thresholds();

[0128] }

[0129] After initialization is completed, the system will enter the real-time monitoring stage.

[0130] The system uses hardware interrupts to monitor the hardware signal loss (LOS) status of the ONU device in real time. The hardware circuit is directly connected to the hardware signal loss detection pin of the ONU device. Once the signal loss is detected, the hardware fault warning signal is immediately triggered through the hardware interrupt.

[0131] As an example, the specific interrupt detection implementation process is as follows:

[0132] void hardware_fault_monitor(){

[0133] while(true){

[0134] / / Detect hardware signal loss status

[0135] if (detect_hardware_los()) {

[0136] / / Trigger hardware failure warning signal

[0137] trigger_hardware_fault_warning();

[0138] / / Execute the corresponding fault handling process

[0139] handle_hardware_fault();

[0140] }

[0141] }

[0142] }.

[0143] Based on hardware fault monitoring, the system further evaluates the channel status in real time by performing underlying detection of channel quality parameters.

[0144] Specifically, the bit error rate detection unit and the signal-to-noise ratio detection unit are used to detect the bit error rate and the signal-to-noise ratio of the channel respectively. When the channel quality is lower than the preset threshold, a channel degradation warning is triggered by a soft interrupt.

[0145] As an example, the specific channel quality parameter bottom layer detection implementation process is as follows:

[0146] void channel_quality_monitor(){

[0147] while(true){

[0148] / / Detect bit error rate

[0149] floatber = detect_ber();

[0150] / / Detect signal-to-noise ratio

[0151] float snr = detect_snr();

[0152] / / Judge whether the channel quality is lower than the preset threshold

[0153] if(ber>BER_THRESHOLD||snr <SNR_THRESHOLD){

[0154] / / Trigger channel degradation warning

[0155] trigger_channel_degradation_warning();

[0156] / / Execute the corresponding channel optimization process

[0157] optimize_channel();

[0158] }

[0159] }

[0160] }.

[0161] Furthermore, a heartbeat detection and registration status change notification mechanism is introduced into the system to achieve comprehensive monitoring of the ONU device status.

[0162] The system can confirm the online status of the device by regularly sending heartbeat signals to the ONU device and receiving responses. At the same time, it monitors the registration status change notification of the ONU device and notifies the system immediately when the status changes.

[0163] As an example, the specific implementation process of the heartbeat detection and registration status change notification mechanism is as follows:

[0164] void heartbeat_and_registration_monitor(){

[0165]

[0166] Finally, based on the intelligent switching algorithm and interrupt notification processing mechanism, the system receives the above fault warnings, channel degradation warnings and heartbeat signal detection results, and comprehensively judges the fault type and severity. Through the preset algorithm and logic, the optimal switching path and recovery strategy are selected and executed. At the same time, through the interrupt notification processing mechanism, rapid response and efficient processing are achieved to ensure the continuity and stability of network connection.

[0167] As an example, the specific implementation process of the heart intelligence switching and interruption notification processing mechanism is as follows:

[0168]

[0169]

[0170] Based on the above monitoring mechanism, when a PON port (such as the main PON port) of the dual-PON port ONU device fails or needs maintenance, it can quickly switch to another PON port (such as the backup PON port) to continue to provide network services. At the same time, during the switching process, the system introduces a MAC synchronization mechanism to synchronize the MAC address to the new PON port, thereby ensuring the continuity and stability of network communication.

[0171] As an example, the specific MAC address synchronization mechanism implementation process is as follows:

[0172]

[0173] }.

[0174] Furthermore, the system also simultaneously introduces network traffic monitoring, security authentication and fault logging mechanisms to perform network traffic monitoring, security authentication and fault logging for ONU devices to fully support network management and maintenance.

[0175] As examples, these functions are implemented through corresponding modules and functions, such as monitor_network_traffic(), perform_security_authentication(), and log_faults().
