Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a fault diagnosis method, device, equipment and medium for a passive optical network system. Background Art

[0002] The Passive Optical Network (PON) is mainly composed of the Optical Network Unit (ONU), the Optical Line Terminal (OLT) and the self-service platform, and the network probe is deployed in the ONU and the platform in a program, which can locate the router or gateway in the network channel. The device with the network probe program installed sends ICMP protocol requests to obtain the probe results such as the path from the local end to other devices and its network delay.

[0003] The analysis and diagnosis of the probe results are crucial. On the one hand, the probe program presents the results more intuitively to the external caller. On the other hand, the probe program can monitor faults in the PON network, identify the fault type, and report the fault to the self-service platform in the form of an alarm.

[0004] At present, there is still a lack of customized models for probe results in PON networks. The self-service platform is temporarily unable to accurately analyze the probe results, and the obtained probe reporting results are still presented with a single probe program as the protagonist. Therefore, integrated probe results, that is, the process of classifying and modeling probe results through the self-service platform, is particularly important. Summary of the invention

[0056] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] The fault diagnosis method of the passive optical network system provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the server 101 is the server of the passive optical network system; device 1 is a device with a probe application installed in the passive optical network; device 2-device n are other devices in the passive optical network. Optionally, the server 101 obtains the global detection data obtained by the probe application to detect each device in the passive optical network system, and constructs the node link corresponding to each device according to the device detection path information in the detection data of each device; wherein the node link corresponding to each device takes the device where the probe application is located as the starting node, the device as the target node, and the device passed by the probe application in the process of reaching the device as the passing node; according to the node link corresponding to each device and the device detection delay information, the passive optical network system is diagnosed.

[0058] In one embodiment, Figure 2As shown, a fault diagnosis method for a passive optical network system is provided, which is described by taking the method applied to a server as an example, and specifically includes the following steps:

[0059] S201, obtaining global detection data obtained by detecting each device in a passive optical network system using a probe application.

[0060] The probe application is a software tool for monitoring and collecting data. Global probing data includes but is not limited to device probing data generated when the probe application probes each device. The device probing data includes device probing path information and device probing delay information. The device probing path information represents the probing path of the probe application when probing the device.

[0061] The device detection delay information characterizes the processing delay and transmission delay of the probe application when detecting the device. In the embodiment of the present application, the device detection delay information corresponding to each device includes the node delay information of each passing node in the node link corresponding to the device; the node delay information of each passing node includes the first transmission delay from the starting node to the passing node, the internal processing delay of the passing node, and the second transmission delay from the passing node to the target node.

[0062] Optionally, the probe application generates the probe data based on the probe process, including the node link list from the device where the probe application is located to other devices, the processing delay of the passing nodes, the transmission delay between each node passed through to the target node (if the value can be calculated), etc. Further, the obtained probe data can be classified to obtain the global probe data for each device.

[0063] S202: Construct a node link corresponding to each device according to the device detection path information in the device detection data.

[0064] Among them, the node link corresponding to each device takes the device where the probe application is located as the starting node, the device as the target node, and the devices that the probe application passes through in the process of reaching the device as the passing nodes.

[0065] Optionally, for any device probed by the probe application, the device is used as the target node of the node link corresponding to the device, the device where the probe application is located is used as the starting node, and the devices that the probe application passes through in the process of reaching the device are used as passing nodes; further, according to the device probe path information, the order of each passing node is determined, and the starting node, each passing node and the target node are connected in sequence according to the order to construct the node link corresponding to the device. Accordingly, this method is used to construct the node links of all devices to obtain a node link table. For example, Figure 3 As shown, it is a node link schematic diagram provided in an embodiment of the present application.

[0066] Exemplarily, the device detection path information may include time information of each device passed by when detecting the device; further, the order of the passing nodes corresponding to each passing device may be determined according to the chronological order.

[0067] S203, performing fault diagnosis on the passive optical network system according to the node link and device detection delay information corresponding to each device.

[0068] Optionally, for a node link corresponding to any device, the node delay information of each passing node in the device detection delay information corresponding to the device is bound to each passing node in the node link. Further, according to the node delay information bound to each passing node, the passive optical network system is diagnosed for faults.

[0069] Exemplarily, it is possible to determine whether the node delay information of each passed node is empty, or whether the first transmission delay, internal processing delay and second transmission delay contained in the node delay information are abnormal, and based on the judgment result, perform fault diagnosis on the passive optical network system.

[0070] In the embodiment of the present application, the fault types of the passive optical network include but are not limited to abnormal node processing delay, abnormal transmission delay, network interruption and abnormal delay jitter.

[0071] In the fault diagnosis method of the above-mentioned passive optical network system, after obtaining the global detection data obtained by the probe application to detect each device in the passive optical network system, including the device detection data generated in the process of the probe application detecting each device, the accuracy of the node links corresponding to each device is ensured according to the device detection path information in the detection data of each device; and the node link corresponding to each device takes the device where the probe application is located as the starting node, the device as the target node, and the device passed by the probe application in the process of reaching the device as the passing node; therefore, the constructed node link can clearly and intuitively describe the detection process of the probe application; further, according to the node link corresponding to each device and the device detection delay information, the passive optical network system is diagnosed, thereby ensuring the flexibility of the fault diagnosis process and the accuracy of the fault diagnosis result.

[0072] Optionally, in one embodiment, Figure 4 As shown, a method for fault diagnosis of a passive optical network system is provided to refine S203 in the above embodiment, and specifically includes the following steps:

[0073] S401, determining abnormal node processing delay of a passive optical network system according to the internal processing delay corresponding to each passing node in the node link corresponding to each device.

[0074] Among them, the node processing delay anomaly indicates that there is an anomaly in the process of processing the transmitted data by the passing device.

[0075] Optionally, the internal processing delay corresponding to each passing node in the node link corresponding to each device can be compared with the internal processing time threshold; if it is identified according to the comparison result that the internal processing delay corresponding to any passing node is greater than the internal processing time threshold, it is determined that there is an abnormal node processing delay failure in the passive optical network system. The internal processing time threshold is a preset internal processing delay threshold. In the embodiment of the present application, the internal processing time threshold can be the average value of the internal processing delay of each device under normal circumstances.

[0076] S402, determining an abnormal transmission delay of the passive optical network system according to a first transmission delay and a second transmission delay corresponding to each passing node in a node link corresponding to each device.

[0077] Among them, the transmission delay anomaly indicates that there is an anomaly in the data transmission process.

[0078] Optionally, for a node link corresponding to any device, if a first transmission delay or a second transmission delay of any passing node in the node link corresponding to the device is greater than a transmission time threshold, it can be determined that an abnormal transmission delay exists in the passive optical network system.

[0079] S403, determining the network interruption status of the passive optical network system according to the node delay information of each node passed in the node link corresponding to each device.

[0080] Optionally, the node delay information of each passing node in the node link corresponding to each device is identified; if the node delay information corresponding to any passing node is identified to be empty, it is determined that the passive optical network system has a network interruption fault. Specifically, for any node link, the node delay information corresponding to each passing node can be checked in sequence along the node link; if the node delay information corresponding to any passing node in the node link is empty, it is determined that the passive optical network system has a network interruption fault.

[0081] In an embodiment of the present application, the passive optical network system also has an abnormal delay jitter fault. Specifically, for any node link, the abnormal delay jitter of the passive optical network can be determined by analyzing the delay variation amplitude of the node delay information corresponding to each passing node in the node link within a period of time.

[0082] In this embodiment, by introducing node processing delay anomalies, transmission delay anomalies and network interruptions, the faults of the passive optical network are classified, and a fault diagnosis method for each fault is provided respectively, thereby ensuring the flexibility of the fault diagnosis process and the accuracy of the fault diagnosis results.

[0083] Optionally, in one embodiment, Figure 5 As shown, a method for determining abnormal transmission delay of a passive optical network system is provided to refine S402 in the above embodiment, and specifically includes the following steps:

[0084] S501, determining the total transmission delay of each node link according to the node delay information corresponding to each passing node in the node link corresponding to each device.

[0085] The total transmission delay is the total delay of the probe from the device where the probe is applied to the device being probed when probing a certain device.

[0086] Optionally, for each device, since the node delay information corresponding to each passing node of the device includes the first transmission delay and the second transmission delay, the first transmission delay and the second transmission delay of all passing nodes in the node link corresponding to the device can be comprehensively considered to comprehensively analyze and calculate the total transmission delay of the node link.

[0087] S502: For any node link, if the total transmission delay of the node link is greater than the total transmission time threshold, and there is any node in the node link whose first transmission delay corresponding to the node is greater than the first transmission time threshold, it is determined that the passive optical network system has an abnormal transmission delay fault.

[0088] The total transmission duration threshold is a preset threshold of the total transmission delay; and the first transmission duration threshold is a preset threshold of the first transmission duration.

[0089] Optionally, for any node link, first compare the total transmission delay of the node link with the total transmission time threshold. If the total transmission delay is greater than the total transmission time threshold, it is necessary to further determine the relationship between the first transmission delay corresponding to each passing node in the node link and the first transmission time threshold. If the first transmission delay corresponding to any passing node in the node link is greater than the first transmission time threshold, it is determined that the passive optical network system has an abnormal transmission delay fault.

[0090] In this embodiment, by introducing the total transmission delay of each node link, the total transmission time threshold and the first transmission time threshold, the transmission delay abnormality fault in the passive optical network can be accurately diagnosed.

[0091] Optionally, in one embodiment, Figure 6 As shown, a method for early warning of abnormal transmission delay fault is provided, which specifically includes the following steps:

[0092] S601: Node links whose total transmission delay is greater than a total transmission time threshold are regarded as abnormal links.

[0093] Optionally, a node link whose total transmission delay is greater than a total transmission time threshold may be selected from the node links corresponding to each device as an abnormal link.

[0094] S602: A node in an abnormal link whose first transmission delay is greater than a first transmission duration threshold is regarded as an abnormal node.

[0095] Optionally, from the selected abnormal links, the transit nodes whose first transmission delay is greater than the first transmission duration threshold are screened out as abnormal nodes.

[0096] S603: Determine the location information of the abnormal transmission delay fault according to the node delay information corresponding to other passing nodes except the abnormal node in the abnormal link.

[0097] Among them, the location information represents the specific node location where the failure occurs.

[0098] It should be noted that the number of abnormal links may be one or more. If the number of abnormal links is more than one, the location information of each abnormal link needs to be determined.

[0099] Optionally, for any abnormal link, other passing nodes in the abnormal link except the abnormal node can be regarded as other nodes; further, combined with the node delay information corresponding to other nodes and the node delay information corresponding to the abnormal node, the specific location of the transmission delay abnormality can be accurately determined and the location information can be generated.

[0100] S604, based on the location information, a transmission delay abnormality fault warning is issued to the passive optical network system.

[0101] Optionally, fault warning information may be generated based on the location information; further, the fault warning information may be sent to a management terminal corresponding to the passive optical network to issue a transmission delay abnormality fault warning to the passive optical network system.

[0102] In this embodiment, by introducing abnormal links and abnormal nodes, a method for accurately determining the location information of abnormal transmission delay failures is provided; further, accurate abnormal transmission delay failure warnings can be timely performed on the passive optical network system based on the location information.

[0110] S704, comparing the internal processing delay corresponding to each passing node in the node link corresponding to each device with the internal processing time threshold.

[0111] S705: If it is identified according to the comparison result that the internal processing delay corresponding to any of the passed nodes is greater than the internal processing time threshold, it is determined that there is an abnormal node processing delay failure in the passive optical network system.

[0112] S706, determining the total transmission delay of each node link according to the node delay information corresponding to each passing node in the node link corresponding to each device.

[0113] S707: For any node link, if the total transmission delay of the node link is greater than the total transmission time threshold, and there is any node in the node link whose first transmission delay corresponding to the node is greater than the first transmission time threshold, it is determined that the passive optical network system has an abnormal transmission delay fault.

[0119] S713: If it is identified that the node delay information corresponding to any of the passed nodes is empty, it is determined that a network interruption fault exists in the passive optical network system.

[0120] The specific process of the above S701-S713 can be found in the description of the above method embodiment. The implementation principle and technical effect are similar and will not be repeated here.
