[0021] 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.

[0022] The implementation of the Passive Optical Network (PON) relies on passive optical devices, such as optical splitters, etc., and does not contain any active electronic devices. It can be understood that the network components in the passive optical network of the present application include passive devices and optical fiber links, and passive devices and optical fiber links are passive optical devices. In industrial scenarios, the passive optical network can be used to collect and transmit the operation data and production data of various equipment in the factory. The application scenarios of passive optical networks in industrial scenarios in enterprises mainly include production networks, office networks, security monitoring networks, etc., especially production networks have extremely high requirements for the stability and reliability of passive optical networks. Once a network failure occurs, it will cause serious impact and huge losses to the production of the enterprise. The traditional health diagnosis method of passive optical networks is to perform artificial fault detection on each network component unit in the passive optical network one by one through fault detection instruments (such as optical power meters and optical time domain reflectometers), and the fault detection efficiency is low. It is understandable that the health diagnosis of the passive optical network through fault detection instruments (such as optical power meters and optical time domain reflectometers) can only determine whether the network components in the passive optical network have failed, but cannot detect whether the network components are in a sub-healthy state, that is, it is impossible to find network components that have not failed but are on the verge of failure, so that operation and maintenance personnel can intervene and maintain network components in a sub-healthy state in a timely manner. Moreover, the failure of the passive optical network has already affected the production and operation of the enterprise, and the stability of the passive optical network cannot be guaranteed.

[0023] However, the present application can collect the performance index parameters of each network component unit in the passive optical network through the network management platform responsible for managing the passive optical network; for each network component unit, when the performance index parameter of the network component unit is greater than the sub-health threshold value of the network component unit, a first sub-health alarm information is issued to indicate that the network component unit is in a sub-health state; wherein the sub-health state is used to characterize that the network component unit has not failed, but is on the verge of failure. Compared with the traditional way of managing passive optical networks by network management platforms, the present application can collect the performance index parameters of each network component unit in the passive optical network, and compare the collected performance index parameters with the sub-health threshold value to automatically determine whether the network component unit in the passive optical network is in a sub-health state, which can improve the sub-health diagnosis efficiency of the passive optical network. When it is found that the network component unit is in a sub-health state, the sub-health alarm information is issued in a timely and automatic manner so that the operation and maintenance personnel can timely maintain the network component unit in a sub-health state to avoid failures in the passive optical network, thereby improving the stability of the passive optical network.

[0024] In one embodiment, Figure 2 As shown, a sub-health diagnosis method for a passive optical network is provided, which is applied to a network management platform responsible for managing the passive optical network, and includes the following steps:

[0025] Step 202: collecting performance index parameters of each network component unit in the passive optical network.

[0026] Among them, the passive optical network includes multiple network components. The network components in the passive optical network include multiple passive devices and multiple optical fiber links, and the optical fiber link is used to connect two passive devices. Each network component corresponds to different performance indicator parameters. The performance indicator parameters are parameters used to characterize the performance indicators of the network component in the working state.

[0027] In one embodiment, a network management platform responsible for managing the passive optical network is deployed in the terminal. The network management platform can monitor each network component unit in the passive optical network in real time and collect performance indicator parameters corresponding to each network component unit.

[0028] Step 204, for each network component unit, when the performance indicator parameter of the network component unit is greater than the sub-health threshold value of the network component unit, a first sub-health alarm message is issued to indicate that the network component unit is in a sub-health state; wherein the sub-health state is used to characterize that the network component unit has not failed yet, but is on the verge of failure.

[0029] Among them, the sub-health threshold value is a threshold value used to determine whether a network component unit is in a sub-healthy state. It can be understood that if the performance index parameter of the network component unit is greater than the sub-health threshold value of the network component unit, the network component unit is determined to be in a sub-healthy state. The sub-healthy state is used to characterize the state in which the network component unit has not failed but is on the verge of failure. If the performance index parameter of the network component unit is less than or equal to the sub-health threshold value of the network component unit, the network component unit is determined to be in a healthy state. The first sub-health alarm information is a sub-health alarm information that is used to remind in the network management platform. The sub-health alarm information is information used to warn that the network component unit is in a sub-healthy state.

[0030] In one embodiment, for each network component unit in the passive optical network, when the performance indicator parameter of the network component unit is greater than the sub-health threshold value of the network component unit, the network management platform can determine that the network component unit is in a sub-healthy state, and issue a first sub-healthy alarm information to indicate that the network component unit is in a sub-healthy state, so that the operation and maintenance personnel can promptly maintain the network component unit in the sub-healthy state to avoid failure of the network component unit, thereby avoiding paralysis of the passive optical network and improving the stability of the passive optical network.

[0031] In one embodiment, for each network component unit in the passive optical network, when the performance indicator parameter of the network component unit is less than or equal to the sub-health threshold value of the network component unit, the network management platform can determine that the network component unit is in a healthy state, and then the network management platform can continue to monitor and continue to collect the performance indicator parameters of the network component unit. It can be understood that when the performance indicator parameter of the network component unit is greater than the sub-health threshold value of the network component unit, the network management platform can determine that the network component unit is in a sub-health state, and issue a first sub-health alarm information for indicating that the network component unit is in a sub-health state.

[0032] In one embodiment, for each network component unit in the passive optical network, when the performance index parameter of the network component unit is greater than the fault threshold value of the network component unit, the network management platform issues a fault alarm information indicating that the network component unit is in a fault state. Among them, the fault threshold value is a threshold value used to determine whether the network component unit is in a fault state, and the fault threshold value is greater than the sub-health threshold value. It can be understood that if the performance index parameter of the network component unit is greater than the fault threshold value of the network component unit, the network component unit is determined to be in a fault state. If the performance index parameter of the network component unit is greater than the sub-health threshold value of the network component unit and less than the fault threshold value, the network component unit is determined to be in a sub-health state. If the performance index parameter of the network component unit is less than or equal to the sub-health threshold value of the network component unit, the network component unit is determined to be in a healthy state.

[0033] In the above-mentioned sub-health diagnosis method of the passive optical network, the performance index parameters of each network component unit in the passive optical network are collected by the network management platform responsible for managing the passive optical network; for each network component unit, when the performance index parameter of the network component unit is greater than the sub-health threshold value of the network component unit, a first sub-health alarm information is issued to indicate that the network component unit is in a sub-health state; wherein the sub-health state is used to characterize that the network component unit has not failed yet, but is on the verge of failure. Compared with the traditional way of managing passive optical networks by network management platforms, the present application can automatically determine whether the network component unit in the passive optical network is in a sub-health state by collecting the performance index parameters of each network component unit in the passive optical network and comparing the collected performance index parameters with the sub-health threshold value, so as to improve the sub-health diagnosis efficiency of the passive optical network. When it is found that the network component unit is in a sub-health state, the sub-health alarm information is issued in a timely and automatic manner so that the operation and maintenance personnel can timely maintain the network component unit in a sub-health state to avoid failure of the passive optical network, thereby improving the stability of the passive optical network.

[0034] In one embodiment, the network component unit includes passive devices in a passive optical network; the performance indicator parameters of the passive devices include the optical transmission power, optical receiving power and operating temperature of the passive devices; the sub-health threshold value of the passive devices includes the optical transmission power threshold value compared with the optical transmission power, the optical receiving power threshold value compared with the optical receiving power, and the operating temperature threshold value compared with the operating temperature threshold value.

[0035] In one embodiment, the network component unit includes a passive device in a passive optical network. The network management platform can collect the optical transmission power, optical receiving power and operating temperature of each passive device in the passive optical network. For each passive device, when the optical transmission power of the passive device is greater than the optical transmission power threshold value of the passive device, or when the optical receiving power of the passive device is greater than the optical receiving power threshold value of the passive device, or when the operating temperature of the passive device is greater than the operating temperature threshold value of the passive device, the network management platform can issue a first sub-health alarm information indicating that the network component unit is in a sub-health state.

[0036] In the above embodiment, by limiting the performance indicator parameters of the passive device to include the optical transmission power, optical receiving power and operating temperature of the passive device, as long as any one of the performance indicator parameters of the optical transmission power, optical receiving power and operating temperature is abnormal, the network component unit will be determined to be in a sub-healthy state and an alarm will be issued, so that the operation and maintenance personnel can more promptly perform health checks and recovery on the network component units in a sub-healthy state, thereby further improving the stability of the passive optical network.

[0037] In one embodiment, the network component unit includes an optical fiber link in a passive optical network; the performance indicator parameters of the optical fiber link include the network delay, jitter parameter and packet loss rate of the optical fiber link; the sub-health threshold value of the optical fiber link includes the network delay threshold value compared with the network delay, the jitter parameter threshold value compared with the jitter parameter, and the packet loss rate threshold value compared with the packet loss rate.

[0038] In one embodiment, the network component unit includes an optical fiber link in a passive optical network. The network management platform can collect network delay, jitter parameter and packet loss rate of each optical fiber link in the passive optical network. For each optical fiber link, when the network delay of the optical fiber link is greater than the network delay threshold value of the optical fiber link, or when the jitter parameter of the optical fiber link is greater than the jitter parameter threshold value of the optical fiber link, or when the packet loss rate of the optical fiber link is greater than the packet loss rate threshold value of the optical fiber link, the network management platform can issue a first sub-health alarm information indicating that the network component unit is in a sub-healthy state.

[0039] In the above embodiment, the performance indicator parameters of the optical fiber link are limited to include the network delay, jitter parameter and packet loss rate of the optical fiber link. As long as any one of the performance indicator parameters of the network delay, jitter parameter and packet loss rate is abnormal, the network component unit will be determined to be in a sub-healthy state and an alarm will be issued, so that the operation and maintenance personnel can perform health checks and recovery on the network component units in a sub-healthy state more promptly, thereby further improving the stability of the passive optical network.

[0040] In one embodiment, the method also includes: obtaining network topology information of the passive optical network; generating a network topology relationship diagram including network components in a sub-healthy state based on the network topology information; and displaying the network topology relationship diagram in a management interface of a network management platform.

[0041] In one embodiment, the network management platform can obtain network topology information of the passive optical network. It can be understood that the network topology information includes association information between all network components in the passive optical network. The network management platform can generate a network topology relationship diagram including network components in a sub-healthy state based on the network topology information, and display the network topology relationship diagram in the management interface of the network management platform for operation and maintenance personnel to view.

[0042] In one embodiment, the network topology relationship diagram may include all network component units in the passive optical network. It can be understood that in addition to the network component units in the sub-healthy state, the network topology relationship diagram may also include all other network component units in the passive optical network.

[0043] In one embodiment, the network topology relationship diagram may also be a part of a complete network topology relationship diagram generated based on the network topology information, wherein the network topology relationship diagram includes network component units that are in a sub-healthy state.

[0044] In the above embodiment, a network topology relationship diagram including network component units in a sub-healthy state is generated based on the network topology information, and the network topology relationship diagram is displayed in the management interface of the network management platform. This can facilitate operation and maintenance personnel to understand in detail the relationship between the network component units in a sub-healthy state and other network component units in the passive optical network, thereby facilitating the operation and maintenance personnel to correctly locate the position of the network component units in a sub-healthy state, so as to timely maintain the network component units in a sub-healthy state, thereby further improving the stability of the passive optical network.

[0045] In one embodiment, the method further includes: obtaining location information of network component units in a sub-healthy state; and displaying the location information in a management interface of a network management platform.

[0046] In one embodiment, when the network component unit in a sub-healthy state is a passive device in a passive optical network, the location information of the passive device may include the passive device in the weak current room information, rack information, and slot information. It can be understood that based on the location information of the passive device, it is possible to directly know which weak current room, rack number, and slot number the passive device in a sub-healthy state is in, so that the operation and maintenance personnel can quickly locate the location of the passive device in a sub-healthy state and go there for maintenance.

[0047] In one embodiment, when the network component unit in a sub-healthy state is an optical fiber link in a passive optical network, the location information of the optical fiber link may include segment information and upper and lower device port information. It can be understood that based on the location information of the optical fiber link, it is possible to directly know in which segment the optical fiber link in a sub-healthy state is located, as well as the upper and lower device port information, so that the operation and maintenance personnel can quickly locate the location of the optical fiber link in a sub-healthy state and go there for maintenance.

[0048] In the above embodiment, by obtaining the location information of the network component unit in a sub-healthy state and displaying the location information in the management interface of the network management platform, it is convenient for operation and maintenance personnel to correctly locate the location of the network component unit in a sub-healthy state, so as to timely maintain the network component unit in a sub-healthy state, thereby further improving the stability of the passive optical network.

[0049] In one embodiment, the method further includes: determining an alarm level of a network component unit in a sub-health state; and sending a second sub-health alarm message to a terminal corresponding to the operation and maintenance personnel by means of a notification indicated by the alarm level.

[0050] The second sub-health warning information is sub-health warning information that is used to remind the operation and maintenance personnel in the corresponding terminal.

[0051] In one embodiment, the network management platform can collect performance indicator parameters of each network component unit in the passive optical network. For each network component unit in the passive optical network, when the performance indicator parameter of the network component unit is greater than the sub-health threshold value of the network component unit, a first sub-health alarm message is issued to indicate that the network component unit is in a sub-health state. The network management platform can also determine the alarm level of the network component unit in a sub-health state, and send a second sub-health alarm message to the terminal corresponding to the operation and maintenance personnel through a notification method indicated by the alarm level.

[0052] In one embodiment, the notification method of the alarm level indication may specifically include an alarm email, an alarm text message, or an alarm phone call. It can be understood that when a certain network component unit plays a core role in the passive optical network, the alarm level of the network component unit can be set to the highest alarm level, and the notification method of its highest alarm level indication is an alarm phone call. Once it is determined that the network component unit is in a sub-healthy state, the network management platform can make a voice call to the terminal corresponding to the operation and maintenance personnel by means of an alarm phone call to convey to the operation and maintenance personnel the second sub-health alarm information that the network component unit is in a sub-healthy state.

[0053] In the above embodiment, by determining the alarm level of the network component unit in a sub-healthy state, a second sub-healthy alarm message is sent to the terminal corresponding to the operation and maintenance personnel through a notification method indicated by the alarm level, so that the operation and maintenance personnel can timely maintain the network component unit in a sub-healthy state. In particular, when the operation and maintenance personnel are not near the location of the network management platform, the second sub-healthy alarm message can be sent to the terminal corresponding to the operation and maintenance personnel so that the operation and maintenance personnel can timely maintain the network component unit in a sub-healthy state, thereby avoiding the occurrence of failures of the network component unit in a sub-healthy state due to untimely maintenance, thereby further improving the stability of the passive optical network.

[0054] In one embodiment, Figure 2 As shown, the passive optical network includes switch 1, switch 2, optical line terminal 1, optical line terminal 2, optical splitter, N optical network units, and multiple optical links. It can be understood that Figure 2Each connecting line in is an optical link. It can be understood that switch 1, switch 2, optical line terminal 1, optical line terminal 2, optical splitter, and N optical network units are passive devices in the passive optical network. The terminal can be deployed with a network management platform, and the network management platform can collect performance index parameters of each network component unit in the passive optical network (i.e., switch 1, switch 2, optical line terminal 1, optical line terminal 2, optical splitter, N optical network units, and multiple optical links). For each network component unit, when the performance index parameter of the network component unit is greater than the sub-health threshold value of the network component unit, a first sub-health alarm information is issued to indicate that the network component unit is in a sub-health state.

[0055] In one embodiment, Figure 3 As shown, the passive optical network includes an optical line terminal, an uplink optical distribution frame, an online optical splitter, a downlink optical distribution frame, an online optical network unit, and multiple optical links. It can be understood that Figure 3 Each solid line connection line in is an online optical link, such as A1 and B2. It can be understood that the optical line terminal, the uplink optical distribution frame, the online optical splitter, the downlink optical distribution frame, and the online optical network unit are passive devices in the passive optical network. The terminal can be deployed with a network management platform, and the network management platform can collect performance index parameters of each network component unit in the passive optical network (i.e., the optical line terminal, the uplink optical distribution frame, the online optical splitter, the downlink optical distribution frame, the online optical network unit, and multiple optical links). For each network component unit, when the performance index parameter of the network component unit is greater than the sub-health threshold value of the network component unit, a first sub-health alarm message is issued to indicate that the network component unit is in a sub-healthy state. It can be understood that when the performance index parameter of the online optical splitter is greater than the sub-health threshold value of the online optical splitter, a first sub-health alarm message is issued to indicate that the online optical splitter is in a sub-healthy state, and the operation and maintenance personnel can replace the spare optical splitter with a new online optical splitter. When the performance index parameter of the online optical network unit is greater than the sub-health threshold value of the online optical network unit, a first sub-health alarm message is issued to indicate that the online optical network unit is in a sub-healthy state, and the operation and maintenance personnel can replace the spare optical network unit with a new online optical network unit.

[0056] For example, see Figure 3When the performance index parameter of the online optical link A1 is greater than the sub-health threshold value of the optical link A1, a first sub-health alarm message is issued to indicate that the optical link A1 is in a sub-healthy state, and the operation and maintenance personnel can replace the spare optical link A2 with a new online optical link. When the performance index parameter of the online optical link B1 is greater than the sub-health threshold value of the optical link B1, a first sub-health alarm message is issued to indicate that the optical link B1 is in a sub-healthy state, and the operation and maintenance personnel can replace the spare optical link B2 with a new online optical link.

[0057] It should be understood that, although each step in the flow chart of the above-mentioned embodiments is shown in order, these steps are not necessarily performed in order. Unless there is a clear explanation in this article, the execution of these steps does not have strict order restrictions, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the above-mentioned embodiments may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these sub-steps or stages is not necessarily performed in order, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

[0058] In one embodiment, Figure 4 As shown, a sub-health diagnosis device 400 for a passive optical network is provided, which is applied to a network management platform responsible for managing a passive optical network. The device specifically includes:

[0059] The acquisition module 402 is used to acquire performance index parameters of each network component unit in the passive optical network;

[0060] The alarm module 406 is used to issue a first sub-health alarm message for each network component unit to indicate that the network component unit is in a sub-health state when the performance indicator parameter of the network component unit is greater than the sub-health threshold value of the network component unit; wherein the sub-health state is used to characterize that the network component unit has not failed yet, but is on the verge of failure.

[0061] In one embodiment, the network component unit includes passive devices in a passive optical network; the performance indicator parameters of the passive devices include the optical transmission power, optical receiving power and operating temperature of the passive devices; the sub-health threshold value of the passive devices includes the optical transmission power threshold value compared with the optical transmission power, the optical receiving power threshold value compared with the optical receiving power, and the operating temperature threshold value compared with the operating temperature threshold value.

Compared with the traditional way of managing passive optical networks by network management platforms, the present application can collect the performance index parameters of each network component unit in the passive optical network, and compare the collected performance index parameters with the sub-health threshold value to automatically determine whether the network component unit in the passive optical network is in a sub-health state, which can improve the sub-health diagnosis efficiency of the passive optical network. When it is found that the network component unit is in a sub-health state, the sub-health alarm information is issued in a timely and automatic manner so that the operation and maintenance personnel can timely maintain the network component unit in a sub-health state to avoid failure of the passive optical network, thereby improving the stability of the passive optical network.
