Description

Technical Field

[0001] The present application relates to the technical field of Passive Optical Network (PON), and in particular to a method and device for determining network failure, and a non-volatile storage medium. Background Art

[0002] Figure 1 The following is a structural diagram of PON. PON is the current mainstream broadband deployment architecture, mainly composed of the optical line terminal (OLT) at the central office, the optical network unit (ONU) at the user side, and the optical distribution node (ODN). ODN is the physical channel for optical transmission between OLT and ONU. It adopts passive optical access technology and is mainly composed of passive optical fibers and passive devices such as optical fiber cables, optical connectors, optical splitters, distribution boxes, and junction boxes. Among them, each node device is a dumb resource and does not have management and maintenance features. The optical fiber line between the OLT and the junction box is the trunk optical fiber line, the optical fiber line between the junction box and the final optical splitter (OBD) is called the branch optical fiber line, and the optical fiber line between the final OBD and the ONU is called the home optical fiber line.

[0003] The outstanding feature of the PON network is that it eliminates outdoor active equipment, so all signal processing functions are completed in the office room and the user's home equipment. Since there are no electronic devices and electronic power supplies in the passive optical network ODN, it cannot be monitored and managed by the element management system (EMS). The existing PON network management has a low accuracy rate in locating passive network faults, which is easy to cause misjudgment and omission. The existing PON network management method for locating passive network faults is to use external equipment to determine the location of the fault through manual on-site testing and inspection; the other is to use an optical time domain reflectometer (Optical Time Domain Reflectometer, OTDR) to test the fault location on-site; the first method takes too long to repair; although the second method can more accurately determine the fault location, it is difficult to popularize on a large scale because the OTDR used in the second method is expensive; and the ODN network maintenance is generally performed by maintenance personnel in different positions responsible for different sections. It is easy to misassign positions due to fault location errors through manual inspection, resulting in low work efficiency. Therefore, in the prior art, when an optical cable disconnection fault occurs, it is impossible to accurately locate the fault location, and it is also impossible to determine whether it is a single user fault or a group fault.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0030] According to an embodiment of the present application, an embodiment of a method for determining a network failure is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] In order to solve the technical problems mentioned in the background technology, the present application provides a method for determining network failures; using big data analysis technology, correlating broadband access server (BAS) authentication and session data such as the online and offline time and reasons for offline of multiple user accounts, and combining resource link information for bottom-up hierarchical clustering analysis and diagnosis, the passive optical network fault location and fault cause can be accurately determined, filling the EMS management blind spot and improving the active fault discovery rate; the method does not require on-site section-by-section testing, and remote detection can be used to locate the fault, so it can greatly shorten the maintenance time and improve the maintenance efficiency. Figure 2 1 is a flowchart of a method for determining a network failure according to an embodiment of the present application. The method can be applied to PON access networks for broadband, interactive Internet Protocol Television (IPTV), and government and enterprise dedicated line services, such as Figure 2 As shown, the method comprises the following steps:

[0032] Step S202, receiving network repair information;

[0033] When there are problems such as inability to connect to the Internet, Internet disconnection, slow Internet access, inability to watch IPTV, program freezes, delays, etc., users will send a repair request.

[0034] Step S204, determining the account information of the first broadband access server that sends the repair information;

[0035] In this step, online session information and authentication data of user accounts on the first broadband access server (BAS) are collected and sorted for subsequent fault analysis.

[0036] Step S206, determining the resource link where the first broadband access server is located and the account information of the target broadband access server, wherein the account of the target broadband access server and the account of the first broadband access server are located on the same resource link;

[0037] When executing step S206, the resource link where the BAS sending the repair information is located and the account information of other BASs on the same resource link are determined; the BAS is mainly responsible for processing the point-to-point protocol (Point-to-PointPotocol Over Ethernet, PPPoE) connection on the user's Ethernet and aggregating user traffic; and cooperates with the authentication system, billing system, customer management system and service policy control system to realize user access authentication, billing and management functions.

[0038] Step S208: determining the fault type corresponding to the network repair information according to the account information of the first broadband access server and the account information of the target broadband access server.

[0039] In this step, when a user reports a problem, the current fault alarm on the user resource link is compared, and rapid fault diagnosis is performed in combination with the real-time online session information of the user account to determine whether the current fault is caused by a network-side fault or a user-side fault, and locate the fault location and cause.

[0040] Through the above steps, the BAS accounts on the same resource link can be analyzed and diagnosed from bottom to top through hierarchical clustering analysis, and various current network-side and user-side fault alarms can be analyzed, including fiber optic cable failure, branch fiber line failure, PON port abnormality, OLT disconnection, etc., to determine the location and cause of the fault.

[0043] According to another optional embodiment of the present application, it is also necessary to obtain the resource link where the first broadband access server is located and the account information of the target broadband access server, wherein the account of the target broadband access server and the account of the first broadband access server are on the same resource link, and the above-mentioned acquisition of the resource link where the first broadband access server is located and the account information of the target broadband access server is divided into the following two processes: obtaining the information of the resource link; obtaining the account information of the target broadband access server.

[0044] According to this embodiment, it is necessary to collect information on the resource link where the first BAS is located, and correspond the collected online session data of the first BAS user account with the information on the resource link where the first BAS is located, and aggregate them from bottom to top in the order of the online status of a single user account (including multiple service access accounts), the online status of multiple user accounts on the same OBD, the online status of multiple user accounts on the same PON port, the online status of multiple user accounts on the same PON board, and the online status of multiple user accounts on the same OLT, and restore the operation status of each user account belonging to the same resource in chronological order.

[0045] According to some optional embodiments of the present application, the information of the resource link obtained includes the following: the central office optical line terminal of the resource link, the passive optical network port of the resource link, the splitter of the resource link, the user side optical network unit of the resource link, and the end-to-end optical routing information of the resource link from the central office to the user end.

[0046] In this optional embodiment, the collected PON resource link information includes: OLT, PON port, OBD, ONU and end-to-end optical routing from the central office to the user end, that is, fiber connection relationship information; obtaining correct user resource link information is conducive to accurately locating faults; the data of the resource management system accurately entered during engineering construction, service activation and installation or maintenance can be used to ensure the accuracy of resource data; the accuracy of resource data can also be ensured by dynamically building resource links.

[0047] According to an optional embodiment of the present application, obtaining the account information of the target broadband access server includes the following steps: obtaining the account information of a second broadband access server on a resource link whose splitter belongs to the same resource link as the account of the first broadband access server; obtaining the account information of a third broadband access server on the resource link whose account belongs to the same passive optical network port as the account of the first broadband access server; obtaining the account information of a fourth broadband access server on the resource link whose account belongs to the same passive optical network board as the account of the first broadband access server; obtaining the account information of a fifth broadband access server on the resource link whose account belongs to the same local optical line terminal as the account of the first broadband access server.

[0049] The collected online session data of the BAS account is matched with the user resource link information, and aggregated from bottom to top in the order of a single user account, to OBD, to PON port, to PON board, and to OLT. During the aggregation process, the operation status of each user account belonging to the same resource is restored along the timeline.

[0050] According to another optional embodiment of the present application, the fault type corresponding to the network repair information is determined based on the account information of the first broadband access server and the account information of the target broadband access server, specifically including the following methods: determining the fault type based on the account information of the first broadband access server, the account information of the second broadband access server and the account information of the third broadband access server; determining the fault type based on the account information of the first broadband access server, the account information of the third broadband access server and the account information of the fifth broadband access server; determining the fault type based on the account information of the first broadband access server, the account information of the fourth broadband access server and the account information of the fifth broadband access server.

[0051] Determining the fault type corresponding to the network repair information based on the account information of the first BAS and the account information of the target BAS specifically includes the following methods: determining the fault type based on the account information of the first BAS, the account status of the second BAS and the account information of the third BAS; determining the fault type based on the account information of the first BAS, the account information of the third BAS and the account information of the fifth broadband BAS; determining the fault type based on the account information of the first BAS, the account information of the fourth BAS and the account information of the fifth BAS.

[0052] Compare the current fault alarm situation on the user resource link, and perform rapid fault diagnosis in combination with the real-time online session information of the user account to determine whether the current fault is caused by a network-side fault or a user-side fault, and locate the fault location and cause. The type and location of the fault can be determined in the following ways: compare the status of the BAS account under the same OBD; compare the status of the BAS account under the same PON port; compare the status of the BAS account under the same PON board; compare the status of the BAS account under the same OLT; determine the cause, location and type of the fault based on the above methods.

[0053] According to another optional embodiment of the present application, the fault type is determined based on the account information of the first broadband access server, the account information of the second broadband access server and the account information of the third broadband access server, including the following steps: if the account information of the first broadband access server is abnormal offline, and the account information of the second broadband access server or the account information of the third broadband access server is not abnormal offline, then the fault type is determined to be a single user fault; if the account information of the first broadband access server and the account information of the second broadband access server are both abnormal offline, and the account information of the third broadband access server is not abnormal offline, then the fault type is determined to be a branch fiber optic line fault.

[0054] Compare the account information of the first BAS and the account information of the second BAS belonging to the same OBD, and compare the account information of the first BAS and the account information of the third BAS belonging to the same PON port; if the account information of the first BAS is abnormally offline, but the account information of the second BAS or the account information of the third BAS is not abnormally offline, determine that the fault type is a single user fault; if the account information of the first BAS and the account information of the second BAS are both abnormally offline, but the account information of the third BAS is not abnormally offline, determine that the fault type is a branch fiber optic line fault.

[0055] In this embodiment, if the account is abnormally offline when the user reports a fault, but other users belonging to the same OBD or the same PON port are normal and do not go offline abnormally at the same time or almost at the same time, then the fault type is determined to be a single user fault. If terminal faults and power outages can be ruled out, then the fault is determined to be a single-user fiber optic failure. If all online users belonging to the same OBD device are abnormally offline at the same time or almost at the same time, but other OBD users under the same PON port are normal, then it is determined that the branch fiber optic line of the OBD has a fault.

[0056] According to another optional embodiment of the present application, the fault type is determined based on the account information of the first broadband access server, the account information of the third broadband access server and the account information of the fifth broadband access server, including the following steps: if the account information of the first broadband access server and the account information of the third broadband access server are both abnormally offline, and the account information of the fifth broadband access server is not abnormally offline, then the fault type is determined to be abnormal passive optical network port status.

[0057] The fault type is determined by comparing the account information of the first BAS and the third BAS belonging to the same PON port, and the account information of the first BAS and the fifth BAS belonging to the same OLT device. If the accounts of the first BAS and the third BAS are both abnormally offline, and the account information of the fifth BAS is not abnormally offline, the fault type is determined to be abnormal status of the passive optical network port.

[0058] As an optional embodiment, if all online users belonging to the same PON port are abnormally offline at the same time or almost at the same time, but other PON ports under the same OLT device are in normal state, the fault is determined to be the abnormal state of the PON port, such as the shared trunk optical path is broken, and the port connected to the handover box is faulty. If the same PON port has the above-mentioned abnormal state of the PON port 2 or more times within 24 hours, the fault is determined to be the unstable state of the PON port, such as the PON is cut over or the PON is man-made.

[0059] According to some optional embodiments of the present application, the fault type is determined based on the account information of the first broadband access server, the account information of the fourth broadband access server, and the account information of the fifth broadband access server, including: if the account information of the first broadband access server and the account information of the fourth broadband access server are both abnormally offline, and the account information of the fifth broadband access server is not abnormally offline, then the fault type is determined to be abnormal status of the passive optical network board; if the account information of the first broadband access server and the account information of the fifth broadband access server are both abnormally offline, then the fault type is determined to be that the central office optical line terminal equipment is offline.

[0060] The fault type can also be determined through the account information of the first BAS, the account information of the fourth BAS, and the account information of the fifth BAS. If the account information of the first BAS and the account information of the fourth BAS belonging to the same PON board are both abnormally offline, but the account information of the fifth BAS belonging to the same OLT device as the account information of the first BAS is not abnormally offline, then the fault type is determined to be abnormal PON board status; if the account information of the first BAS and the account information of the fifth BAS are both abnormally offline, then the fault type is determined to be OLT device disconnection.

[0061] In this optional embodiment, if all online users belonging to the same OLT device abnormally go offline at the same time or almost at the same time, it is determined that the fault is that the OLT device is disconnected from the network, and the cause of the OLT device being disconnected from the network may be an OLT device failure or a power outage.

[0063] The receiving module 30 is used to receive network repair information.

[0064] The first determining module 32 is used to determine the account information of the first broadband access server that sends the repair report information.

[0066] The analysis module 36 is used to determine the fault type corresponding to the network repair information according to the account information of the first broadband access server and the account information of the target broadband access server.

[0067] According to the device provided by this optional embodiment, real-time monitoring of the overall situation of PON access network faults provides a basis for formulating optimal emergency repair plans, efficient scheduling, maintenance evaluation, etc.; during the implementation process, there is no need to adapt and debug EMS equipment from different manufacturers and various test interface protocols, and there is no need to add management and collection equipment to each ODN node, which reduces the complexity of the system structure and the costs of manpower, equipment, time, etc.

[0068] According to this embodiment, a specific implementation scheme is provided. Figure 4 The flowchart of locating PON access network faults through the above implementation scheme divides the operations required to be performed when locating PON access network faults into three parts: operations of the data service layer, operations of the interface service layer and operations of the business service layer.

[0069] The data service layer includes: data cache service module and data storage service module. When locating the PON access network fault, collect real and effective user online session information data; real and effective user flow information data and PON access network user resource link and topology structure information data, and save the collected information data in the data service layer; among which, the user flow information data can be the upstream flow data of user IPv4 and IPv6 or the downstream flow data of user IPv4 and IPv6.

Through data interfaces, page components, data push, etc., the Web page provides detection service capabilities to output and analyze data to internal and external network users and operation and maintenance apps.

[0072] The business service layer includes: flow information collection and cleaning service module, online and offline information collection and cleaning service module, topology data collection and cleaning service module, data analysis service module and data storage and collection service module. When locating the PON access network fault, the above data stored in the data service layer, such as online session information data, user flow information data, user resource link and topology information data, and all user online data, are read, converted, cleaned, analyzed and collected. Figure 8 A schematic diagram of the functional principle of the business service layer.

[0073] Through the above operation, when the user reports a repair, the current fault alarm situation on the user resource link can be compared, and the real-time online session information of the user account can be combined to perform rapid fault diagnosis, determine whether the current fault is caused by a network side fault or a user side fault, and locate the fault location and cause; remote and accurate positioning of the PON access network fault can be achieved, and the technical effect of timely discovering fault information and accurately dispatching fault personnel to the post for repair can be achieved.
