Description

Technical Field

[0001] This invention belongs to the technical field of camera network fault location, specifically relating to a method and system for tracing the source of faults in an OTN-borne camera service network. Background Technology

[0002] OTN (Optical Transport Network) is a high-speed, high-capacity, flexible, and reliable communication network based on optical transmission technology. OTN transmission technology is widely used in mobile networks, meeting their demands for high capacity, low latency, high reliability, and multi-service support. For example... Figure 2 As shown, to further enhance the user experience of video surveillance services, an OptiX OSN9600 M24 can be used as the core, and an OptiX OSN 1800 V Pro can be used for core and backbone networking to build a dedicated network for video surveillance.

[0003] Under the same service carrying network, once the core equipment, transmission equipment, optical cable, central office equipment, etc. fail, the manifestation is the interruption of the surveillance camera service, and troubleshooting is required. As the number of monitoring points and scenarios continues to expand, troubleshooting will become more complex, the professional requirements for troubleshooting personnel will be higher, and the troubleshooting time will be longer.

[0004] The existing troubleshooting method involves: business maintenance personnel checking the power supply and network connectivity at the camera locations; central office maintenance personnel checking for power outages and network connectivity issues at the central office terminal equipment; transmission network maintenance personnel checking for fiber optic cable interruptions; and NCE network management and monitoring personnel checking for transmission equipment alarms and CPE equipment alarms. This existing troubleshooting method involves multiple professionals and personnel on-site, which is both time-consuming and labor-intensive, resulting in very slow troubleshooting and delayed service restoration.

[0005] In summary, the main problems in troubleshooting network faults for camera video surveillance services carried by Optical Transport Networks (OTNs) are as follows:

[0006] ① Numerous systems and cumbersome operations: The front end has a video management platform and a resource system, while the back end network side has an NCE network management system; once a fault occurs, it is necessary to coordinate multiple people to log in to multiple systems to conduct multi-angle data fault diagnosis.

[0007] ② Difficulty in performance and fault location: There are many systems involved in the front-end and back-end, as well as a large number of network elements and personnel; performance degradation or faults may occur in each link of the end-to-end link, making it difficult to quickly and accurately locate the fault point in real time.

[0008] ③ Fault diagnosis cannot be comprehensive and multi-faceted: Because there are many front-end and back-end systems and network elements, there are many factors that affect the customer's perception of performance and faults, making it impossible to locate the fault from all angles.

[0009] ④ Lack of data transparency: Operations and maintenance personnel, installation and maintenance staff, and account managers often do not have data query permissions for various backend systems on the network side. They need the cooperation of backend personnel to query and then provide feedback, which is not conducive to real-time troubleshooting and handling of faults on site. Summary of the Invention

[0010] The purpose of this invention is to provide a method and system for tracing the source of faults in OTN-borne camera service networks, in order to solve the above-mentioned problems.

[0011] This invention is mainly achieved through the following technical solutions:

[0012] A method for tracing faults in an OTN-based camera service network includes the following steps:

[0013] Step S1: Collect alarm data from the NCE network management system in real time via the syslog protocol. If there are any uncleared alarm data, return the corresponding diagnostic conclusion based on the type of alarm data; otherwise, proceed to step S2.

[0014] Step S2: Real-time detection of the received optical power of the CPE device by connecting to the NCE network management system. If the received optical power of the CPE device is normal, proceed to step S3; otherwise, return to the diagnosis conclusion of the pigtail / optical module fault in the CPE station of the central office equipment.

[0015] Step S3: Perform network connectivity test by pinging the camera IP address. If the network is reachable, proceed to step S4; otherwise, return the diagnosis that the camera IP address is not reachable.

[0016] Step S4: Connect to the video management platform and check the online status data of the camera's IP address in the video management platform in real time. If it is online, return a diagnosis conclusion that all indicators are normal; otherwise, return a diagnosis conclusion that the camera is offline in the video management platform.

[0017] To better implement the present invention, further, in step S1, the alarm data includes alarm data with alarm titles NE_NOT_LOGIN and R_LOS, as well as alarm data with BD_STATUS or ETH_LOS or ETH_LINK_DOWN. The alarm data with alarm title NE_NOT_LOGIN is used to determine whether the OSN 1800 device is offline, the alarm data with alarm title R_LOS is used to determine whether the link between the 1800 and the 1800 transmission device is interrupted, and the alarm data with alarm titles BD_STATUS or ETH_LOS or ETH_LINK_DOWN is used to determine whether the CPE device is offline or the end fiber is interrupted.

[0018] To better implement the present invention, further, in step S1, alarm data with alarm title NE_NOT_LOGIN is queried based on the unique identifiers of the NCE network management system and the 1800 local device; alarm data with alarm title R_LOS is queried based on the unique identifiers of the NCE network management system and the 1800 peer device; and alarm data with alarm title BD_STATUS, ETH_LOS, or ETH_LINK_DOWN is queried based on the unique identifiers of the NCE network management system, the 1800 local device, and the CPE device.

[0019] To better realize the present invention, further, in step S2, the received optical power data of the CPE device is queried based on the unique identifiers of the NCE network management system, the 1800 local device, and the CPE device.

[0020] To better realize the present invention, if the received optical power of the CPE equipment is -60dBm, then the diagnostic conclusion of the pigtail / optical module fault in the CPE station of the central office equipment is returned.

[0021] To better implement this invention, further, in step S1, based on the camera's IP address, the CPE terminal information, 1800 device information, NCE network management information, and video management platform information where the device is installed are queried in the resource system; the CPE terminal information includes the CPE name, unique identifier, port number, slot number, 1800 name, and 1800 port number; the 1800 device information includes the 1800 device IP address, unique identifier, manufacturer, model, NCE network management system, local device information, and peer device information; the NCE network management information includes the unique identifier, manufacturer, syslog protocol, and syslog alarm collection IP address; the video management platform information includes the platform address and protocol information.

[0022] This invention is mainly achieved through the following technical solutions:

[0023] An OTN-based camera service network fault tracing system, based on the aforementioned OTN-based camera service network fault tracing method, includes a data acquisition module and, from front to back, an alarm data diagnosis module, a CPE device light receiving diagnosis module, a camera IP address diagnosis module, and a platform online diagnosis module.

[0024] The data acquisition module is used to query the CPE terminal information, 1800 device information, NCE network management information, and video management platform information where the camera is installed in the resource system based on the camera's IP address; the alarm data diagnosis module is used to diagnose faults based on uncleared alarm data; the CPE device receiving light diagnosis module is used to diagnose whether the CPE at the central office is experiencing a fault in its internal pigtail / optical module by detecting the receiving light power of the CPE device; the camera IP address diagnosis module is used to perform network accessibility testing by using the Ping command and pinging the camera's IP address; and the platform online diagnosis module is used to detect and query the online status of the camera's IP address in the video management platform.

[0025] The beneficial effects of this invention are as follows:

[0026] This invention integrates and solidifies the diagnostic process for camera fault location and analysis using IT methods, connecting multiple system interfaces. Based on CPE terminal information, 1800 device information, NCE network management information, and video management platform information, it achieves fault diagnosis for surveillance video services carried by OTN optical networks. By connecting system interfaces and strengthening front-end and back-end collaboration, this invention forms a fault diagnosis system integrating query, analysis, and location, achieving precise fault location and rapidly improving fault handling efficiency. This invention's method of solidifying the process through IT means eliminates the need for on-site personnel, significantly saving manpower and enabling rapid and precise fault location of cameras carrying video surveillance services on optical transmission networks within seconds.

[0027] This invention effectively shortens fault location time: One-click fault diagnosis enables rapid fault location of surveillance cameras within seconds, significantly reducing the time required. This invention also effectively improves fault location accuracy: By utilizing the unique identifiers of NCE network management, resource systems, video management platforms (NCE network management, 1800, CPE, and camera IP addresses), and based on real-time alarm data and logical judgment, the fault location can be accurately determined. Furthermore, this invention transforms the complex diagnostic process into a systematic and automated one: By solidifying the diagnostic process through IT, fault location can be automated, eliminating the need for front-end and back-end personnel to log into multiple systems or for maintenance personnel to conduct on-site troubleshooting. This invention significantly improves the efficiency and accuracy of fault location for camera video surveillance services carried by OTN optical transmission networks, ultimately leading to higher customer satisfaction and a more stable network environment.

[0030] Example 1:

[0031] A method for tracing the source of faults in an OTN-borne camera service network, such as Figure 1 As shown, it includes the following steps:

[0032] (1) Query the basic resource information of the NCE network management system, 1800 device and CPE terminal to which the camera IP address belongs;

[0033] Network Control and Management (NCE) is a network management system based on cloud computing architecture. NCE is a crucial tool for enterprises and organizations to achieve digital transformation. It enables comprehensive management and monitoring of enterprise network resources through a network cloud platform, improving network reliability and security, and enhancing network efficiency and operational levels.

[0034] CPE is an acronym for Customer Premise(s) Equipment, referring to any connectivity device used to access the Internet or typically access services on a provider's network, whether directly or indirectly connected to that network. The CPE will be located on the customer side of the network and can serve as a boundary between the provider's network (WAN) and the customer's home network (LAN).

[0035] OptiX OSN 1800 is a high-performance, highly integrated optical transmission platform launched by Huawei.

[0036] The OptiX OSN 9600 M24 is a new generation of high-capacity, intelligent OTN cross-connection scheduling equipment launched by Huawei.

[0037] (2) Collect alarm data from the NCE network management system in real time via the syslog protocol;

[0038] a. Query the real-time alarm data of the NCE network management system, and check whether there are any uncleared NE_NOT_LOGIN alarms on the 1800 local end. If so, return the diagnosis conclusion that the transmission device 1800 is offline based on the alarm title NE_NOT_LOGIN, and determine whether the OSN 1800 device is offline.

[0039] b. Query the real-time alarm data of the NCE network management system, and check whether there are any uncleared R_LOS alarms on the port of the peer device that has a fiber optic connection with the 1800, in order to determine whether the link between the 1800 and the 1800 transmission device is interrupted. If so, return the diagnosis conclusion that the backbone link between the 1800 transmission devices is interrupted based on the alarm title R_LOS.

[0040] c. Query the real-time alarm data of the NCE network management system, and check whether there are any uncleared BD_STATUS\ETH_LOS\ETH_LINK_DOWN alarms in the CPE terminal to determine whether the CPE device is offline or the end fiber is interrupted. If so, return the diagnosis conclusion that the CPE device is offline or the end fiber is interrupted based on the alarm title BD_STATUS\ETH_LOS\ETH_LINK_DOWN.

[0041] (3) Query the real-time alarm data of the NCE network management system, and detect the light emission power and light reception power of the CPE equipment in real time. If the light reception power of the CPE equipment is abnormal, return the diagnosis conclusion of the pigtail / optical module fault in the CPE station of the central office equipment.

[0042] (4) Use the Ping command to check in real time whether the IP address of the monitoring camera device is reachable. If it is not reachable, return the diagnosis conclusion that the CPE of the central office device is online and the IP address of the camera is not reachable.

[0043] Ping (Packet Internet Groper) is a tool used to test network connectivity. It determines whether the target host is online and measures network latency by sending ICMP (Internet Control Message Protocol) echo requests to the target host and waiting for a response.

[0044] (5) By connecting to the camera video management platform, the system can detect in real time whether the camera data configuration is normal and whether the camera is online. If it is not online, the system will return a diagnostic conclusion that the CPE at the central office is online, the camera IP address is accessible on the network, and it is not online on the video platform. Otherwise, the system will return a diagnostic conclusion that all indicators of the end-to-end fault one-click diagnosis are normal.

[0045] A video management platform is a management platform system provided by camera hardware manufacturers. By configuring data such as the IP address of the camera in the platform, it enables the management of surveillance camera devices; it can also view the video of the camera monitoring equipment in real time and check the online status of the camera.

[0046] This invention is a network fault tracing solution for camera video surveillance services carried by OTN optical transmission networks. It mainly obtains data such as resources, alarms, and optical power performance by connecting multiple system interfaces such as resource systems, NCE network management, and video management platforms. The obtained data is analyzed and combined with ping detection methods to achieve real-time end-to-end link fault diagnosis of camera devices and output fault diagnosis conclusions. This effectively improves the real-time performance, comprehensiveness, and accuracy of network fault diagnosis for video surveillance services carried by OTN optical transmission networks.

[0047] Example 2:

[0048] A method for tracing network faults in OTN-borne camera services, based on existing alarm feature data and camera configuration data from the NCE network management system, performs real-time network fault diagnosis on the video surveillance services of OTN-borne cameras to determine the location of network faults.

[0052] A4. Based on the unique identifiers of the NCE network management system, 1800 local device, and CPE device in A1, query alarm data with an alarm status of BD_STATUS, ETH_LOS, or ETH_LINK_DOWN that have not been cleared; if there are any uncleared records with alarm titles of BD_STATUS, ETH_LOS, or ETH_LINK_DOWN in the interface data, return the fault diagnosis conclusion and end the fault location process;

[0053] A5. Based on the unique identifiers of the NCE network management system, 1800 local device, and CPE device in A1, query the received optical power and emitted optical power data of the CPE device; if the received optical power of the CPE device is -60dBm in the interface data, return the fault diagnosis conclusion and end the fault location process.

[0054] A6. Use the Ping command to ping the camera's IP address to perform network connectivity testing; in the interface data, determine whether the packet loss rate in the feature data returned by the ping command is 100%; if so, return the fault diagnosis conclusion and end the fault location process.

[0055] A7. According to the video management platform protocol in A1, query the online status data of the camera IP address in the video management platform; in the interface data, determine whether the camera IP address status returned by the interface is online. If online, return a diagnostic conclusion that all indicators of the end-to-end fault one-click diagnosis are normal; otherwise, return a diagnostic conclusion that the central office equipment CPE is online, the camera IP address has network access, and is offline on the video platform.

[0056] This invention effectively shortens fault location time: One-click fault diagnosis enables rapid fault location of surveillance cameras within seconds, significantly reducing the time required. This invention also effectively improves fault location accuracy: By utilizing the unique identifiers of NCE network management, resource systems, video management platforms (NCE network management, 1800, CPE, and camera IP addresses), and based on real-time alarm data and logical judgment, the fault location can be accurately determined. Furthermore, this invention transforms the complex diagnostic process into a systematic and automated one: By solidifying the diagnostic process through IT, fault location can be automated, eliminating the need for front-end and back-end personnel to log into multiple systems or for maintenance personnel to conduct on-site troubleshooting.
