Description

Technical Field

[0001] This invention relates to the field of network monitoring technology, and in particular to a method and related equipment for monitoring network link status in a professional network. Background Technology

[0002] Specialized networks are dedicated communication services provided to specific industries or sectors, such as finance, energy, and healthcare. They are distinct from public networks and are built upon the specific business needs, security standards, and operational specifications of different industries. They serve as crucial basic transmission channels for ensuring the security and confidentiality of information and data within various industries, as well as for the stability and reliability of network communications. They are of great significance for safeguarding public services, stabilizing economic operations, strengthening public safety, and promoting technological innovation.

[0003] However, network link failures and performance degradation occur frequently. Physical hardware failures, cyberattacks, natural disasters, and software and configuration anomalies can all lead to network link interruptions. Network link interruptions can cause catastrophic losses to society and pose a severe test to social stability. Furthermore, due to the unique nature of professional networks being completely isolated from public networks, abnormal network link conditions are often not detected in a timely manner, and are usually only discovered after a loss has occurred. Therefore, timely monitoring of network link status and prompt early warning of sudden network link anomalies are particularly important for ensuring social security and stability.

[0004] Currently, link status monitoring in professional networks mainly relies on regular manual inspections and simple network testing tools. These methods often suffer from untimely monitoring and alerting.

[0005] Therefore, developing a method that can efficiently monitor network link status and issue timely alerts is of great significance for ensuring the stable operation of professional networks. Summary of the Invention

[0006] The main objective of this invention is to provide a method and related equipment for monitoring network link status in a professional network, which can quickly and efficiently detect abnormal network link status and issue alarms, while ensuring the network security of the dedicated network.

[0007] To achieve the above objectives, this application provides a network link status monitoring method for a professional network, applied to a network link status monitoring device connected to a server; the method includes:

[0008] Under normal circumstances, when the communication service program is running, the status log file is updated at preset time intervals;

[0009] If an anomaly is detected in the program running the communication service, the timed update of the status record file will be interrupted.

[0010] An interrupt notification signal is sent through a physically isolated transmission medium, and the interrupt notification signal is used to trigger alarm information.

[0011] This application also provides a network link status monitoring device, including:

[0012] The data processing module is used to detect whether the program running the communication service is normal; when the program running the communication service is normal, it updates the status record file at preset time intervals; when an abnormality is detected in the program running the communication service, it interrupts the timed update of the status record file.

[0013] The data storage module is used to store the status record file;

[0014] The signal transmitting module is used to send an interruption notification signal through a physically isolated transmission medium, and the interruption notification signal is used to trigger alarm information.

[0015] This application also provides a network link status monitoring system, including a server, a target device, and a network link status monitoring device as described in the first aspect.

[0016] In another aspect, this application provides an electronic device including a memory and a processor, the memory storing a computer program that, when executed by the processor, causes the processor to perform steps as described in the first aspect and any possible implementation thereof.

[0017] In another aspect, this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, causes the processor to perform the steps of the method described in the first aspect.

[0018] This application provides a method and related equipment for monitoring network link status in a dedicated network. The method is applied to a network link status monitoring device connected to a server. When the program running the communication service is functioning normally, the status log file is updated at preset time intervals. If an anomaly is detected in the program running the communication service, the timed update of the status log file is interrupted. An interruption notification signal is sent through a physically isolated transmission medium, which triggers alarm information. Currently, dedicated networks are limited by network security requirements and are usually physically isolated from external networks. Network link anomalies are difficult to detect in a timely manner, leading to service interruptions and causing significant socio-economic losses and security risks. This method can efficiently detect network link status and promptly issue alarm information while meeting the network security requirements of the dedicated network. Attached Figure Description

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0025] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] The infrared light emitting module mentioned in this application embodiment is a device capable of emitting infrared light signals, typically used for short-range wireless communication. Specifically:

[0028] Transmission frequency: Short-wave infrared light is typically used, with wavelengths ranging from 700 nanometers to 1400 nanometers.

[0029] Signal strength: The signal strength needs to be sufficient to be reliably detected by the receiving module in a physically isolated environment.

[0030] The TCP (Transmission Control Protocol) mentioned in this application embodiment is a connection-oriented, reliable, byte-stream-based transport layer communication protocol. The TCP protocol establishes a connection through a three-way handshake, ensuring the reliability of data transmission. It uses ACK (Acknowledgment) signals to ensure the correct reception of data packets, and performs timeout retransmissions if no acknowledgment signal is received, ensuring the integrity of data transmission. ACK signals typically contain information such as acknowledgment number and sequence number.

[0031] The physical isolation mentioned in this application refers to the physical isolation between networks to ensure that data cannot be directly transmitted between networks.

[0032] The embodiments of this application are described below with reference to the accompanying drawings.

[0033] Please see Figure 1 This is a flowchart illustrating a network link status monitoring method for a professional network provided in an embodiment of this application. Figure 1 As shown, the method includes:

[0034] 101. Under normal operating conditions of the communication service program, update the status log file at preset time intervals;

[0035] 102. If an anomaly is detected in the program running the communication service, the timed update of the above-mentioned status record file shall be interrupted;

[0036] 103. Send an interrupt notification signal through a physically isolated transmission medium. The interrupt notification signal is used to trigger alarm information.

[0037] In this embodiment of the application, the subject executing the method can be a network link status monitoring device, which is connected to a server, specifically through a physical external interface.

[0038] The preset time interval can be set and adjusted as needed, for example, set to 5 minutes.

[0039] In this application embodiment, program anomalies in running communication services include various abnormal situations such as communication interruption between the program running communication services and upstream and downstream nodes, program freeze, and even hardware failure.

[0040] Specifically, under normal operating conditions, the built-in monitoring module's log file can be updated at preset time intervals. When the program experiencing communication interruptions with upstream and downstream nodes, freezes, or even hardware failures, the scheduled updates to the built-in monitoring module's status log file will be interrupted, triggering an alarm.

[0041] The communication interruption mentioned above in this application embodiment can be determined by methods such as TCP interruption or data transmission / reception timeout, and no restrictions are imposed here.

[0042] The preset timeout period can be set and adjusted as needed, for example, set to 1 minute.

[0043] In one implementation, TCP interruption detection can be used. For example, if the above response signal is not received within a preset timeout period, the status log file will stop its periodic updates. An interruption notification signal can be sent through a physically isolated transmission medium to trigger an alarm.

[0044] In an optional implementation, the method further includes:

[0045] Upon receiving the aforementioned interruption notification signal, the aforementioned alarm information is sent through the external network.

[0046] Correspondingly, upon receiving the aforementioned interruption notification signal, the receiving module can trigger an alarm and send alarm information via the external network. Specifically, it can send a network interruption SMS alarm to the built-in contacts. Optionally, other alarm formats or content may also be available.

[0047] In an optional implementation, the above-mentioned transmission of the interruption notification signal via a physically isolated transmission medium includes:

[0048] Send N infrared pulse signals, where N is an integer greater than 1.

[0049] Specifically, taking a preset timeout of 1 minute as an example, if the transmitting end does not receive a response signal after 1 minute, it can trigger an infrared pulse signal. The receiving module will then trigger an alarm upon receiving the infrared pulse signal.

[0050] If the response signal times out each time, multiple infrared pulse signals can be sent continuously, for example, two shortwave infrared pulses can be sent; then the receiving module can trigger an alarm after receiving two infrared pulse signals.

[0051] Currently, dedicated networks are limited by network security requirements and are usually physically isolated from external networks. Network link anomalies are difficult to detect in a timely manner, which can lead to business interruptions and cause huge social and economic losses and security risks. The method in this application embodiment can efficiently detect network link status and issue alarm information in a timely manner while meeting the network security requirements of dedicated networks.

[0052] Based on the description of the foregoing method embodiments, this application also provides a network link status monitoring device.

[0053] The network link status monitoring device in this embodiment can be used to detect the connectivity of the data link between two-level servers in a dedicated network. In application, monitoring can be performed by connecting an external monitoring device through a physical interface on the primary server of the dedicated network.

[0054] In one implementation, the network link status monitoring device can be referenced. Figure 2 As shown, the network link status monitoring device 200 includes a data processing module 210, a data storage module 220, and a signal transmission module 230, wherein:

[0055] The aforementioned data processing module 210 is used to detect whether the program running the communication service is normal; when the program running the communication service is normal, it updates the status record file at preset time intervals; when an abnormality is detected in the program running the communication service, it interrupts the timed update of the aforementioned status record file.

[0056] The aforementioned data storage module 220 is used to store the aforementioned status record file;

[0057] The aforementioned signal transmitting module 230 is used to send an interrupt notification signal through a physically isolated transmission medium, and the interrupt notification signal is used to trigger alarm information.

[0058] The data storage module 220 has a built-in status log file, including a reception count log file, which can be updated periodically, for example, it can be set to update every 5 minutes.

[0059] Optionally, the network link status monitoring device 200 may also include:

[0060] Signal receiving module 240 is used to receive the above-mentioned interrupt notification signal;

[0061] The information transmission module 250 is used to send the alarm information through an external network when the interruption notification signal is received.

[0062] Alternatively, the signal transmitting module 230 described above may be an infrared light transmitting module;

[0063] The aforementioned infrared light emitting module is specifically used to send two infrared pulse signals.

[0064] Specifically, when using an infrared light emitting module, the signal receiving module 240 is an infrared light receiving module. The infrared light receiving module is normally in standby mode, and can activate the information transmission module upon receiving an infrared pulse signal. Short-wave infrared technology is used to ensure reliable signal transmission even in physically isolated environments.

[0065] The information transmission module 250 can identify specific infrared pulse signals to avoid false triggering. Furthermore, the information transmission module 250 can preset recipient information, such as built-in alarm SMS templates and alarm recipient numbers. The alarm format can be adjusted as needed, for example, it can be set to send two alarm SMS messages within one minute of activation, thus ensuring that alarm information is received promptly. This module sends alarm information through an external network channel, ensuring timely notification to relevant personnel even in physically isolated environments.

[0066] Optionally, the SMS message may include key information such as the time and location of the link interruption.

[0067] Optionally, the network link status monitoring device 200 also includes a built-in power module 260, which is connected to a physical external interface and is powered by a server.

[0068] Specifically, the built-in power module 200 can be connected to the server's physical external interface, allowing the server to provide power to the testing equipment, which has a rated power of 2W. Powering the equipment via the server's physical external interface ensures continuous operation while the server is running, and its low-power design makes it suitable for long-term operation.

[0069] For example, the workflow of a network link status monitoring device may include:

[0070] Initialization: The detection device obtains power from the server through its built-in power module and starts the data processing module.

[0071] Periodic detection: The data processing module, based on the TCP protocol, sends test data to the lower-level server every 5 minutes and waits for the ACK confirmation signal to be returned.

[0072] Status update: If an ACK confirmation signal is received within 1 minute, the data processing module updates the reception count record file in the data storage module and records the link status as normal.

[0073] Interruption detection: If no ACK confirmation signal is received for more than 1 minute, the data processing module determines that the link is interrupted and sends a start signal to the infrared light transmitting module.

[0074] Infrared signal transmission: After receiving the start signal, the infrared light emitting module emits two infrared pulse signals.

[0075] SMS Alarm: After the infrared light receiving module receives the infrared pulse signal, it activates the SMS alarm module and sends a network interruption alarm SMS to the preset contact.

[0076] Figure 3 This is a schematic diagram of another network link status monitoring device provided in an embodiment of this application. Figure 3 As shown, the structure and functions of this network link status monitoring device are described in detail below:

[0077] Physical external interface: This interface is the part that physically connects the detection device to an external server or other device, and is used to transmit power and data.

[0078] Power Module: The power module is responsible for providing the necessary power to the testing equipment. It obtains power from the server through a physical external interface and converts it into the voltage and current required by the various modules inside the equipment.

[0079] Storage module: The storage module is used to store data generated during the operation of the detection device, such as link status records (status log files), alarm information, etc. It may include flash memory, hard disk, or other types of non-volatile memory.

[0080] Processing Module: The processing module is the core of the testing equipment, responsible for performing tasks such as data processing, protocol processing, and status monitoring. It may include one or more microprocessors or microcontrollers.

[0081] Information transmission module: This module is responsible for transmitting information within the detection equipment, and may include functions such as data reception, processing and transmission.

[0082] One-way infrared light receiving module: This module receives infrared light signals from the one-way infrared light emitting module. These signals are typically used to transmit link interruption information in physically isolated network environments.

[0083] One-way infrared light emitting module: The one-way infrared light emitting module is used to emit infrared light signals when a link interruption is detected. These signals are received by the infrared light receiving module, thereby enabling communication in physically isolated environments.

[0084] The unidirectional infrared light receiving module and the unidirectional infrared light transmitting module are the key communication mechanisms in the solution, allowing the transmission of link status information without violating physical isolation requirements. This design ensures the security of the professional network while enabling effective monitoring and alarm of network link status.

[0085] Based on the description of the foregoing method embodiments, this application also discloses a network link status monitoring system.

[0086] This network link status monitoring system mainly includes a server, target devices, and such as... Figure 2 The network link status monitoring device shown here will not be described in detail here.

[0087] In one specific implementation, the network link state monitoring system includes:

[0088] Level 1 Server: Equipped with physical interfaces for connecting network link status monitoring devices and providing power and communication support.

[0089] Subordinate servers: Deployed at various key nodes in the network, they can receive test signals from network link status monitoring devices and return confirmation signals.

[0090] Network link status monitoring equipment includes a built-in power module, data storage module, data processing module, infrared light emitting module, infrared light receiving module, and SMS alarm module.

[0091] The SMS alarm module includes built-in alarm SMS templates and preset contact numbers, enabling it to send SMS messages via the external network.

[0092] Management platform: Deployed on a primary server, it communicates with the detection equipment via the network, monitors the link status in real time, and records alarm events.

[0093] The workflow of this system is described below:

[0094] initialization:

[0095] The testing equipment connects to the primary server via a physical interface, obtains power from the server, and initializes each module.

[0096] The management platform starts up, establishes a communication connection with the testing equipment, and monitors the link status in real time.

[0097] Link status monitoring:

[0098] The data processing module of the testing equipment is based on the TCP protocol and sends test data to the lower-level server every 5 minutes.

[0099] After receiving the test data, the lower-level server returns an ACK confirmation signal;

[0100] The data processing module of the testing equipment receives the confirmation signal and updates the reception count record file in the data storage module.

[0101] Link interruption detection:

[0102] If the detection device does not receive an ACK confirmation signal within 1 minute, the data processing module determines that the link is interrupted. It can also determine the interruption in other ways, such as data transmission and reception timeout.

[0103] The data processing module sends a start signal to the infrared light emitting module;

[0104] After receiving the start signal, the infrared light emitting module emits two infrared pulse signals.

[0105] SMS alerts:

[0106] After receiving the infrared pulse signal, the infrared light receiving module activates the SMS alarm module;

[0107] The SMS alarm module sends network interruption alarm SMS messages via the external network based on the built-in alarm SMS templates and preset contact numbers;

[0108] The SMS alarm module can send two alarm SMS messages within one minute of startup to ensure that alarm information is received in a timely manner.

[0109] Management platform monitoring:

[0110] The management platform receives link status data and alarm information sent by the detection equipment in real time;

[0111] The management platform displays the link status through a visual interface, including normal and interrupted status;

[0112] The management platform records alarm events and provides historical data query functions, making it convenient for network administrators to troubleshoot and analyze faults.

[0113] This system is suitable for professional network environments with high network security requirements, such as those in finance, energy, and healthcare. By monitoring link status in real time and issuing timely alarms, it can effectively ensure the stable operation of the network and reduce business losses and security risks caused by link interruptions.

[0114] In practical applications, based on the various protocol-based detection, hardware device-based detection, and software tool and platform-based detection methods currently used in professional networks, combined with the processing module in this application, it is possible to quickly, efficiently, and accurately monitor and perceive the network links and status of professional network chains.
