Description

Technical Field

[0001] The present invention belongs to the technical field of camera network fault location, and in particular relates to a method and system for tracing camera service network faults carried by OTN. Background Art

[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 and can meet the needs of mobile networks for high capacity, low latency, high reliability and multi-service support. Figure 2 As shown in the figure, to further improve the user experience of video surveillance services, the OptiX OSN9600 M24 can be used as the core and the OptiX OSN 1800 V Pro can be used for core and backbone networking to build a dedicated network for video surveillance.

[0003] In the same service-carrying network, once the core equipment, transmission equipment, optical cables, local equipment, etc. fail, the surveillance camera service will be interrupted, and troubleshooting will be required. With the continuous expansion of monitoring points and scenes, troubleshooting will become more complicated, requiring higher professionalism from troubleshooters and taking longer time.

[0004] The existing troubleshooting method is: business maintenance personnel go to the camera point to check the power supply and network connection; the central office maintenance personnel check whether the central office terminal equipment is powered off and the network connection; the transmission network maintenance personnel check whether the optical cable is disconnected; the NCE network management monitoring personnel check the transmission equipment alarm and CPE equipment alarm. The existing troubleshooting involves multiple professionals and multiple personnel on-site inspections, which is time-consuming and laborious. The troubleshooting is very untimely and the service cannot be restored for a long time.

[0005] In summary, the current network troubleshooting of camera video surveillance services carried by the Optical Transport Network (OTN) mainly has the following problems: ① There are many systems and the operations are complicated: there are video management platforms and resource systems on the front end, and NCE network management on the back end network side; once a failure occurs, it is necessary to coordinate multiple people to log in to multiple systems separately to perform multi-angle data fault diagnosis.

[0006] ② Difficulty in performance and fault location: There are many systems involved in the front-end and back-end, as well as many network elements and personnel. Performance degradation or failure 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.

[0007] ③ Fault diagnosis cannot be comprehensive and multi-angle: Because there are many front-end and back-end systems and network elements, there are many factors that affect customer-perceived performance and faults, and it is impossible to locate the fault from all angles.

[0008] ④ Data opacity: Operation and maintenance, installation and maintenance, customer managers, etc. often do not have data query permissions for the various back-end systems on the network side. Back-end personnel are required to cooperate with support queries and then provide feedback, which is not conducive to real-time troubleshooting and handling of faults on site. Summary of the invention

If the network is accessible, proceed to step S4, otherwise return a diagnostic conclusion that the camera IP address is unreachable; Step S4: Connect to the video management platform, and check and query the online status data of the camera IP address in the video management platform in real time.

[0015] In order to better implement the present invention, further, in the step S1, according to the IP of the camera, 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, unique identifier, manufacturer, model, NCE network management, local device information and opposite 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.

NCE is one of the important tools for enterprises and organizations to achieve digital transformation. It can manage and monitor enterprise network resources in an all-round way through the network cloud platform, improve network reliability and security, and improve the efficiency and operation level of enterprise networks.

[0021] CPE is an acronym for Customer Premise(s) Equipment and refers to any connected device used to access the Internet or generally services on a provider's network, whether directly or indirectly connected to that network. The CPE will be on the customer side of the network and can be the demarcation point between the provider's network (WAN) and the customer's home network or (LAN).

[0022] OptiX OSN 1800 is a high-performance, highly integrated optical transmission platform launched by Huawei.

[0023] OptiX OSN 9600 M24 is a new generation of large-capacity, intelligent OTN cross-connect dispatching equipment launched by Huawei.

[0024] (2) Collect NCE network management alarm data in real time through syslog protocol; a. Query the real-time alarm data of the NCE network management to which it belongs, and check whether there is an uncleared NE_NOT_LOGIN alarm on the local end of the 1800. 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; b. Query the real-time alarm data of the NCE network management to which it belongs, and check whether there is an uncleared R_LOS alarm on the port of the opposite device that has an optical fiber connection with the 1800 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 transmission devices 1800 is interrupted according to the alarm title R_LOS; c. Query the real-time alarm data of the NCE network management to check whether there are any uncleared BD_STATUS\ETH_LOS\ETH_LINK_DOWN alarms on the CPE terminals to determine whether the CPE device is offline or the end fiber is disconnected.

According to the unique identifiers of the NCE network management, 1800 local device, and CPE device in A1, query the CPE device's received optical power and luminous power data; in the interface data, if the CPE device's received optical power is -60dbm, return the fault diagnosis conclusion and end the fault location process; A6. Ping the camera IP address through the Ping command to detect network accessibility. In the interface data, determine whether the packet loss rate in the characteristic data returned by the ping command is 100%. If yes, return the fault diagnosis conclusion and end the fault location process. 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 it is online, return the diagnosis conclusion that all indicators of the end-to-end fault one-key diagnosis are normal; otherwise, return the diagnosis conclusion that the local equipment CPE is online, the camera IP address is accessible on the network, and it is not online on the video platform.
