[0001] This application relates to the field of optical communication technology, and in particular to a monitoring method, apparatus, device, and medium for an optical network unit. Background Technology

[0002] PON (Passive Optical Network) technology is widely used in fiber optic access. A PON network specifically includes: an OLT (Optical Line Terminal) at the central office, an ONU (Optical Network Unit) at the user end, and an optical distribution network connecting the OLT and ONU. Monitoring the ONU allows for real-time understanding of the network status at the user end, which helps to provide more stable and higher-quality network services.

[0003] In related technologies, OLT manufacturers provide network management systems. By logging into the OLT manufacturer's network management system, you can find an OLT and view the performance information of the ONUs connected to that OLT.

[0004] However, in practical applications, a PON network may contain OLTs from multiple manufacturers. In this case, to meet the monitoring needs of all ONUs in a PON network, it is necessary to log into the network management systems of multiple manufacturers and find the corresponding OLTs in order to view the ONU performance information.

[0058] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] The monitoring method for optical network units in this application can be used in PON networks to understand the network status of user terminals in real time, thereby helping to provide more stable and higher quality network services.

[0060] In related technologies, OLT manufacturers provide network management systems. By logging into the OLT manufacturer's network management system, you can find an OLT and view the performance information of the ONUs connected to that OLT.

[0061] However, in practical applications, a PON network may contain OLTs from multiple manufacturers. In this case, to meet the monitoring needs of all ONUs in a PON network, it is necessary to log into the network management systems of multiple manufacturers and find the corresponding OLTs in order to view the ONU performance information. Logging into and searching through multiple manufacturers' network management systems is time-consuming and laborious, impacting the efficiency of ONU monitoring.

[0062] To address the technical problem of low monitoring efficiency of optical network units in related technologies, this application provides a monitoring method for optical network units. This method is applied to a server, which is coupled with an aggregation switch, an optical line terminal (OLT), and an optical network unit (ONU). The aggregation switch has a transparent transmission configuration, enabling it to transparently transmit VLAN (Virtual Local Area Network) broadcasts between the server and the ONU. Specifically, the method may include the following steps:

[0063] Automatically discovers the device serial numbers of ONUs within a preset range, creates monitoring ONUs and monitoring items for the monitoring ONUs based on the discovered device serial numbers, and associates the monitoring items with the device serial numbers; the monitoring items are used to collect preset performance information of the monitoring ONUs.

[0064] Based on the collection results corresponding to the above monitoring items, determine the performance information corresponding to the monitored ONU;

[0065] Based on the device serial number associated with the monitoring item, the OLT connected to the ONU represented by the device serial number, and the aggregation switch connected to the OLT, the database stores the data records corresponding to the aggregation switch, OLT, device serial number and performance information.

[0066] Display the first selection control corresponding to the aggregation switch, the second selection control corresponding to the OLT, and the third selection control corresponding to the device serial number;

[0067] Based on the user's selection operation on the first, second, or third selection control, the corresponding first target data record is searched in the database and displayed.

[0068] First, in the data acquisition network built in this application embodiment, the aggregation switch transmits VLAN broadcast between the server and the ONU, enabling the server to collect the preset performance information of the ONU via VLAN broadcast, and providing network link support for data transmission during the monitoring process of the ONU.

[0069] Secondly, the server in this embodiment automatically discovers the SN (Serial Number) of ONUs within a preset range. This automatic discovery of the ONU SN can be applied to any ONU from any manufacturer. Therefore, this embodiment can utilize the automatic discovery of the ONU SN to monitor ONUs from multiple manufacturers, thereby saving the login and search costs of network management systems from multiple manufacturers and thus improving ONU monitoring efficiency.

[0070] Furthermore, in this embodiment of the application, monitoring ONUs and monitoring items for monitoring ONUs are created based on the discovered device serial numbers, and the monitoring items are associated with the device serial numbers, which can realize the automatic collection of the collection results corresponding to the monitoring items.

[0071] Furthermore, this embodiment determines the performance information corresponding to the monitored ONU based on the collection results corresponding to the aforementioned monitoring items; it stores data records corresponding to the aggregation switch, OLT, device serial number, and performance information in the database based on the device serial number associated with the monitoring item, the OLT connected to the ONU represented by the device serial number, and the aggregation switch connected to the OLT; and it provides selection controls for dimensions such as aggregation switch, OLT, and device serial number in the data records. Thus, this embodiment allows users to filter and select ONU performance information based on dimensions such as aggregation switch, OLT, and device serial number, thereby further improving the monitoring efficiency of ONUs.

[0072] For example, a user can select the target aggregation switch to view based on the first selection control, and the system can provide the user with performance information of all ONUs under the target aggregation switch.

[0073] For example, by selecting the target OLT to view based on the second selection control, the user can be provided with the performance information of all ONUs under the target OLT.

[0074] For example, when a user selects the target SN to view based on the third selection control, the system can provide the user with performance information of the specific ONU corresponding to the target SN.

[0075] Method Example 1

[0076] refer to Figure 1 This diagram illustrates a step-by-step flowchart of a monitoring method for an optical network unit according to an embodiment of this application. The method is applied to a server, which is coupled to an aggregation switch, an optical line terminal (OLT), and an optical network unit (ONU). The aggregation switch has a transparent transmission configuration to enable it to transparently transmit VLAN broadcasts between the server and the ONU. Specifically, the method may include the following steps:

[0077] Step 101: Automatically discover the device serial numbers of ONUs within the preset range. Based on the discovered device serial numbers, create a monitoring ONU and a monitoring item for the monitoring ONU, and associate the monitoring item with the device serial number. The monitoring item is used to collect preset performance information of the monitoring ONU.

[0078] Step 102: Based on the collection results corresponding to the above monitoring items, determine the performance information corresponding to the monitored ONU;

[0079] Step 103: Based on the device serial number associated with the monitoring item, the OLT connected to the ONU represented by the device serial number, and the aggregation switch connected to the OLT, save the data records corresponding to the aggregation switch, OLT, device serial number and performance information in the database.

[0080] Step 104: Display the first selection control corresponding to the aggregation switch, the second selection control corresponding to the OLT, and the third selection control corresponding to the device serial number;

[0081] Step 105: Based on the user's selection operation on the first selection control, the second selection control, or the third selection control, search for the corresponding first target data record in the database and display the first target data record.

[0082] Figure 1 At least one step of the method shown can be executed by the server. The server can determine the performance information corresponding to the monitored ONU according to the monitoring method of the optical network unit in the embodiments of this application, and save the data records corresponding to the aggregation switch, OLT, device serial number and performance information in the database, supporting users to filter and select performance information from multiple dimensions.

[0083] In this embodiment, the server is coupled with the aggregation switch, optical line terminal (OLT), and optical network unit (ONU) to form a data acquisition network. This data acquisition network can be used to collect preset performance information from the ONU.

[0084] Reference Figure 2 The diagram shows a schematic of the structure of a data acquisition network according to an embodiment of this application. The data acquisition network specifically includes: a server, an aggregation switch 202, an optical line terminal 203, and an optical network unit 204.

[0085] Among them, server 201 is the core of the data acquisition network and is responsible for managing the entire data acquisition network.

[0086] Server 201 can communicate with aggregation switch 204 via network protocols such as SNMP (Simple Network Management Protocol) and HTTP (Hypertext Transfer Protocol) to collect and process preset performance information of ONUs.

[0087] Aggregation switch 202 is a key device in the network, responsible for connecting devices at different network layers. In the data acquisition network, aggregation switch 202 is responsible for transparently transmitting VLAN broadcasts between server 201 and optical line terminal 203.

[0088] In practical applications, the aggregation switch 202 can be multi-layered. For example, if city A includes multiple counties, then the Layer 3 switch 202 can include: a first aggregation switch for city A and second aggregation switches corresponding to each of the multiple counties. It is understood that this application embodiment does not limit the specific layers of the aggregation switch or the number of Layer 3 aggregation switches included in each layer.

[0089] In a specific implementation, server 201 can be connected to aggregation switch 202 via a switch. Furthermore, one aggregation switch 202 can connect to multiple optical line terminals 203. Of course, this embodiment does not limit the specific number of optical line terminals 203 connected to one aggregation switch 202.

[0090] The optical line terminal 203 is the central device of the optical fiber access network, responsible for managing multiple optical network units 204. It connects to the optical network units 204 via optical fibers to provide high-speed optical fiber access services.

[0091] Optical Network Unit 204 is a user-end device used to provide fiber optic access services.

[0092] The process of performing transparent transmission configuration on the above-mentioned aggregation switch in this embodiment of the application specifically includes: configuring the port mode of the aggregation switch as a Trunk port; and configuring the VLAN to which the Trunk port is joined.

[0093] In this embodiment, VLAN is a communication technology that logically divides a physical local area network (LAN) into multiple broadcast domains. Hosts within a VLAN can communicate directly, while hosts in different VLANs cannot communicate directly with each other, thus isolating broadcast domains. A VLAN identifier can refer to the identifier of a virtual LAN, used to distinguish different VLANs.

[0094] Trunk, or port aggregation, is a software configuration technique that combines two or more physical ports into a single logical path, increasing bandwidth between the aggregation switch and network nodes. It merges the bandwidth belonging to these ports, providing each port with several times the dedicated bandwidth of an individual port. Trunk is an encapsulation technology; it's a point-to-point link where both ends can be aggregation switches, aggregation switches and routers, or hosts and aggregation switches or routers. Based on port aggregation, it allows parallel connections and simultaneous transmission between aggregation switches, between aggregation switches and routers, and between hosts and aggregation switches or routers via two or more ports.

[0095] Since the trunk port can forward packets with VLAN tags, the data from the optical network unit 204 can reach the server 201 via the aggregation switch 202.

[0096] In this embodiment of the application, the VLAN to which the Trunk port is joined can be configured, and the VLAN identifier to which the Trunk port is joined can be configured. The VLAN identifier to which the Trunk port is joined can be a numerical range, such as 2 to 4094.

[0097] In step 101, a monitoring tool that supports network discovery protocols can be used to scan a preset range of IP (Internet Protocol) addresses to discover ONUs in the network. Commonly used network discovery protocols include SNMP, LLDP (Link Layer Discovery Protocol), and CDP (Cisco Discovery Protocol).

[0098] For example, monitoring tools that support network discovery protocols may include Zabbix. Zabbix is ​​an enterprise-grade open-source solution that provides distributed system and network monitoring capabilities based on a web (World Wide Web) interface. Zabbix can monitor various network parameters to ensure the secure operation of server systems and provides a flexible notification mechanism to allow system administrators to quickly locate and resolve various problems. Zabbix specifically includes a Zabbix server and an optional Zabbix agent. The Zabbix server can provide monitoring and data collection functions for remote devices (ONU in this embodiment) through methods such as SNMP, Zabbix agent, and port monitoring. It can run on operating systems such as Linux.

[0099] The preset IP address range can be determined by those skilled in the art based on actual application needs. For example, if it is necessary to monitor ONUs in multiple counties of City A, the IP address range for each county can be determined according to the network plan of City A. The combination of IP address ranges from multiple counties can be used as the preset IP address range.

[0100] SN (Serial Number) is a unique identifier assigned by the manufacturer to each device to distinguish and identify different devices. Serial numbers typically contain a combination of letters and numbers and are used to track product manufacturing, sales, and warranty information.

[0101] In one implementation of this application, the data acquisition network communicates according to the Simple Network Management Protocol (SNMP).

[0102] Step 101 automatically discovers the device serial numbers of ONUs within a preset range, and based on the discovered device serial numbers, creates a monitoring ONU and monitoring items for the monitoring ONU. This process specifically includes:

[0103] Step A1: Create an auto-discovery rule; the auto-discovery rule specifies a first SNMP object identifier corresponding to the device serial number of a preset manufacturer, and the first SNMP object identifier is used to represent the object identifier corresponding to the device serial number of the preset manufacturer.

[0104] Step A2: Create a first preset action for the automatic discovery rule, so as to execute the first preset action when the automatic discovery rule discovers the device serial number of the preset manufacturer; the first preset action is specifically: create a monitoring ONU and a monitoring item for the monitoring ONU according to the discovered device serial number.

[0105] In practical applications, the configuration functions of monitoring tools such as Zabbix can be used to execute steps A1 to A3. Step A1 specifically involves rule configuration. Step A2 specifically involves action configuration. Since step A2 creates a first preset action for the auto-discovery rule, the association between the auto-discovery rule and the first preset action can be established. In practice, the configuration interface for the first preset action can include the name of the auto-discovery rule, thus enabling the association between the auto-discovery rule and the first preset action.

[0106] Therefore, in this embodiment of the application, a first preset action corresponding to the automatic discovery rule is executed according to the automatic discovery rule; wherein, the automatic discovery rule specifies a first SNMP object identifier corresponding to the device serial number of a preset manufacturer, and the first SNMP object identifier is used to characterize the object identifier of the device serial number of the preset manufacturer; the first preset action instructs to create a monitoring ONU and a monitoring item for the monitoring ONU based on the discovered device serial number.

[0107] The number of preset manufacturers can be one or more. This application does not limit the specific number of preset manufacturers.

[0108] An SNMP OID (Object Identifier) ​​is a value defined within a specific MIB (Management Information Base) schema to define a specific SNMP target in the MIB database. An SNMP OID is a delimited sequence of numbers forming a period from abc...xyz. It is a unique identifier for each item in the information and is part of a MIB. The SNMP protocol groups various device parameters into a tree structure. Starting from the root of the tree, each level node has a code. These level codes are separated by ".", and the resulting string is called an OID. Operations can be performed on the parameters represented by the OID. SNMP-monitored items (monitoring items) are individual OIDs.

[0109] The Management Information Base (MIB) is part of the TCP / IP (Transmission Control Protocol / Internet Protocol) network management protocol standard framework. The MIB defines the data items that managed devices must store, the operations allowed on each data item, and their meanings. In other words, data variables such as control and status information of managed devices accessible to the system are stored in the MIB.

[0110] The first SNMP object identifier is an object identifier that represents the serial number of a device from a pre-defined manufacturer. Different pre-defined manufacturers can correspond to different first SNMP object identifiers. In practical applications, the first SNMP object identifier can be queried in the pre-defined manufacturer's MIB.

[0111] After the automatic discovery rules are configured, monitoring tools such as Zabbix will periodically execute the following steps according to the set update intervals: Scan a predefined range of IP addresses using the SNMP protocol; for each IP address, send an SNMP request to query the device serial number. If the ONU responds to the SNMP request, the ONU will obtain the device's serial number; determine whether the obtained serial number already exists in the serial number set; if not, it considers a new device discovered and saves the obtained serial number to the serial number set. The SNMP request here can be a device serial number retrieval request.

[0112] This application embodiment can associate automatic discovery rules with a first preset action, so that when the automatic discovery rules discover the device serial number of a preset manufacturer, the first preset action is executed; the first preset action is specifically: based on the discovered device serial number, create a monitoring ONU and a monitoring item for the monitoring ONU.

[0113] In practical applications, the above monitoring items may correspond to a second SNMP object identifier, which is used to characterize the object identifier corresponding to the preset performance information of the monitoring ONU of the preset manufacturer.

[0114] In specific implementations, preset performance information may include: operating status, offline reason, received optical power, uplink bandwidth utilization, downlink bandwidth utilization, CPU utilization, and memory utilization, etc. It is understood that those skilled in the art can use various preset performance information according to actual application requirements, and the embodiments of this application do not limit the specific preset performance information.

[0115] It should be noted that, in addition to collecting preset performance information of the monitored ONU, the monitoring items in this application embodiment can also be used to collect relevant time information of the preset performance information of the monitored ONU. Taking the preset performance information as the running state as an example, the relevant time specifically includes: the change time from the first state to the second state, or the duration of the first state or the second state, etc. The first state and the second state can be different subordinate concepts of the running state.

[0116] It should be noted that, in addition to collecting preset performance information of the monitored ONU, the monitoring items in this application embodiment can also be used to collect OLT information of the monitored OLT corresponding to the monitored ONU. Examples of OLT information may include information such as OLT interface utilization. Interface utilization reflects the data transmission efficiency and load of the OLT interface, which is crucial for ensuring network performance and planning network expansion.

[0117] Different preset performance information can correspond to different second SNMP object identifiers. In practical applications, the second SNMP object identifier can be queried in the preset manufacturer's MIB.

[0118] In the above scenario, the collection result corresponding to the monitoring item specifically includes: the value of the second identifier corresponding to the second SNMP object identifier; the value of the second identifier can be a value corresponding to some preset performance information represented by the second SNMP object identifier. Taking the second SNMP object identifier representing received optical power as an example, the second identifier can be a value of received optical power.

[0119] In step 102, the process of determining the performance information corresponding to the monitored ONU based on the collection results corresponding to the monitored item specifically includes: converting the second identifier value into the performance information corresponding to the monitored ONU based on the mapping relationship between the SNMP object identifier value and the interpretation information.

[0120] Taking the preset performance information as the operating state as an example, Table 1 shows an example of the mapping relationship between SNMP object identifier values ​​and their explanatory information. This mapping relationship can be provided by the MIB. In one example, the explanatory information in the mapping relationship between SNMP object identifier values ​​and their explanatory information in the MIB can be in English. This embodiment of the application can utilize machine translation technology to convert the English explanatory information into Chinese explanatory information.

[0123] In one optional embodiment of this application, the above method may further include: determining the collection mode corresponding to the monitoring ONU connected to the OLT based on the number of ONUs connected to the OLT; wherein, when the number of ONUs is greater than a number threshold, the collection mode is a passive collection mode; when the number of ONUs is not greater than the number threshold, the collection mode is an active collection mode.

[0124] Configure the collection mode of the monitoring item according to the collection mode corresponding to the monitoring ONU;

[0125] Collect the collection results corresponding to the monitoring items according to the collection mode of the monitoring items.

[0126] Active data collection refers to the server proactively sending a data collection request to the monitoring ONU to obtain the data collection results corresponding to the monitored items. Passive data collection refers to the server not proactively sending a data collection request, but instead waiting for the monitoring ONU to proactively report the data collection results corresponding to the monitored items.

[0127] In this embodiment, a passive data collection mode is adopted when the number of ONUs exceeds a threshold. Since passive data collection does not require the server to actively send requests, but instead acquires data by monitoring network traffic, it consumes less network bandwidth and device resources on the server. Furthermore, to reduce network traffic on the server side, the passive data collection interval can be between 5 and 10 seconds.

[0128] In this embodiment, when the number of ONUs does not exceed a threshold, an active data collection mode is adopted. The server can control the time interval of active data collection and adjust the collection strategy as needed to adapt to different network conditions and requirements. For example, the time interval of active data collection can be approximately 1 second.

[0129] In summary, this embodiment determines the collection mode corresponding to the monitoring ONU connected to the OLT based on the number of ONUs connected to the OLT. Since different collection modes can correspond to different numbers of ONUs, this embodiment can make reasonable use of bandwidth and reduce the CPU and memory overhead of the server.

[0130] In step 103, this embodiment of the application can store data records corresponding to the aggregation switch, OLT, device serial number and performance information in the database based on the device serial number associated with the monitoring item, the OLT connected to the ONU represented by the device serial number, and the aggregation switch connected to the OLT.

[0131] Assuming a performance data table is used to store data records corresponding to the aggregation switch, OLT, device serial number, and performance information, Table 2 shows an example of a performance data table according to an embodiment of this application. It should be noted that a performance data table can contain one or more types of performance information. Table 2 shows performance information such as operating status. The aforementioned data records specifically include four fields: aggregation switch, OLT, device serial number, and performance information. Specifically, the aggregation switch field can contain the serial number string of the aggregation switch to which the monitoring NOU belongs; the OLT field can contain the serial number string of the OLT to which the monitoring NOU belongs; the device serial number can be the string corresponding to the SN of the monitoring NOU; and the operating status can be the explanatory information corresponding to the operating status of the monitoring NOU.

[0132] In practical applications, one aggregation switch typically corresponds to multiple OLTs, and one OLT typically corresponds to multiple device serial numbers. The operating status corresponding to a device serial number is unique at any given time.

[0133] Table 2

[0134] Aggregation Switch OLT Device serial number Running status Aggregation Switch A OLTA1 SNA11 Online Aggregation Switch A OLTA1 SNA12 Offline Aggregation Switch A OLTA1 SNA13 Optical signal loss …… …… …… ……

[0135] It should be noted that, in addition to the four fields of aggregation switch, OLT, device serial number and performance information, the above data records may also include other fields such as relevant time.

[0136] It should be noted that the embodiments of this application can utilize monitoring tools such as Zabbix, which support network discovery protocols, to execute steps 101 to 103. The monitoring tool can not only automatically discover monitored ONUs belonging to multiple preset manufacturers within a preset range, but also automatically create monitoring items for monitored ONUs, automatically determine the collection results of the monitoring items, and determine the performance information corresponding to the collection results; it can also save the performance information and related fields to a database.

[0137] Steps 104 and 105 can be performed using a visualization tool. Examples of visualization tools include Grafana, Kibana, etc.

[0138] Grafana is an open-source data visualization tool that helps users graphically display and monitor data from data sources in real time, enabling them to understand the data more intuitively. Grafana supports various data sources, including databases, and various display methods, such as charts, dashboards, maps, and calendars.

[0139] In step 104, this embodiment of the application may display a first selection control corresponding to the aggregation switch, a second selection control corresponding to the OLT, and a third selection control corresponding to the device serial number.

[0140] In practical applications, the first selection control can be a radio button or a checkbox. For example, the first selection control can be the first radio button corresponding to "All Aggregator Switches," selecting which option selects all aggregation switches. Alternatively, the first selection control can be the second radio button corresponding to "Single Aggregator Switch," selecting which option selects the single aggregation switch.

[0141] Similarly, the second selection control can be a radio button or a checkbox. For example, the second selection control can be the third radio button corresponding to "All OLTs". Selecting the third radio button will select all OLTs or all OLTs corresponding to "Single Aggregation Switch". The second selection control can also be the fourth radio button corresponding to "Single OLT". Selecting the fourth radio button will select the "Single OLT".

[0142] Similarly, the third selection control can be a radio button or a checkbox. For example, the third selection control can be the fifth radio button corresponding to "All SNs," selecting the fifth radio button will select all SNs. The third selection control can also be the sixth radio button corresponding to "Single SN," selecting the sixth radio button will select the "single SN."

[0143] In step 105, this embodiment of the application can search for the corresponding first target data record in the database based on the user's selection operation on the first selection control, the second selection control, or the third selection control, and then display the first target data record.

[0144] Reference Figure 3The diagram illustrates a monitoring interface of an optical network unit according to an embodiment of this application, which may include: an aggregation switch area 301, an OLT area 302, an SN area 303, and a performance information area 304. The performance information area 304 is specifically used to display performance information such as the operating status.

[0145] Specifically, the first selection controls in the aggregation switch area 301 include a first radio button 311 for "All Aggregation Switches" and a second radio button 312 for "Single Aggregation Switch". Selecting the first radio button 311 will select all aggregation switches. Selecting the second radio button 312 will select a single aggregation switch.

[0146] The second selection controls in OLT area 302 specifically include a third radio button 321 corresponding to "All OLTs" and a fourth radio button 322 corresponding to "Single OLT". Selecting the third radio button 321 will select all OLTs or all OLTs corresponding to "Single Aggregation Switch". Selecting the fourth radio button 322 will select a "Single OLT".

[0147] The third selection controls in SN area 303 specifically include: a fifth radio button 331 corresponding to "All SNs" and a sixth radio button 332 corresponding to "Single SN". Selecting the fifth radio button 331 will select all SNs or all SNs corresponding to a single OLT. Selecting the sixth radio button 332 will select a single SN.

[0148] The performance information area 304 can be used to display the operating status of the selected SN.

[0149] Figure 3 In this embodiment, if the user selects the second radio button 312 corresponding to aggregation switch A, then multiple target OLTs corresponding to aggregation switch A will be selected. In this embodiment, multiple first target data records corresponding to aggregation switch A can be queried in the database.

[0150] Assuming the first target data record contains all fields from the performance data table, the query statement for retrieving multiple first target data records corresponding to aggregation switch A from the performance data table in the database can be:

[0151] SELECT*

[0152] FROM table_name

[0153] WHERE field_name = 'Aggregation Switch A'

[0154] Where table_name is the name of the performance data table, and field_name is the field name of the aggregation switch.

[0155] Assuming the first target data record contains the target field from the performance data table, the query statement for retrieving multiple first target data records corresponding to aggregation switch A from the performance data table in the database can be:

[0156] SELECT column1,column2,column3

[0157] FROM table_name

[0158] WHERE field_name = 'Aggregation Switch A'

[0159] Where table_name is the name of the performance data table, field_name is the field name of the aggregation switch, and column1, column2, and column3 are the names of the target fields.

[0160] In an optional embodiment of this application, the method may further include: exporting the first target data record as a first target data table. For example, a user can analyze the performance information of aggregation switch A based on the exported first target data table to improve the accuracy of ONU monitoring.

[0161] In another optional embodiment of this application, the above method may further include: displaying multiple options corresponding to performance information; based on the user's selection operation for a target option among the multiple options, searching in the database for a second target data record corresponding to the target option, and displaying the second target data record.

[0162] In practical applications, drop-down options can be used to provide multiple options corresponding to performance information. This application embodiment can provide multiple drop-down options for users to choose from. These multiple drop-down options can correspond to specific field content for a certain performance information. For example, Table 1 shows eight interpretations of the running status, which can correspond to eight drop-down options. Users can select a target option from these eight options. Assuming the target option corresponds to "offline," this application embodiment can search the database for the second target data record corresponding to the target option and display that record. In this way, the ONU information containing the specific performance information corresponding to the target option can be presented to the user.

[0163] This application embodiment can also export the second target data records as a second target data table. For example, based on the second target data table corresponding to "offline", the user can analyze all "offline" ONUs to accurately determine the cause of offline status.

[0164] In yet another optional embodiment of this application, the above method may further include:

[0165] Step B1: Create a trigger rule; the trigger rule specifies the monitoring item and trigger conditions; the trigger conditions are specifically: the collection results of the monitoring item meet preset conditions;

[0166] Step B2: Create a second preset action for the triggering rule; establish the association between the triggering rule and the second preset action so that the second preset action is executed when the collection result of the monitoring item meets the preset conditions; the second preset action is specifically: send alarm information to a preset user using a preset medium.

[0167] The triggering rules in this application embodiment can be used to detect monitoring items and triggering conditions, and when the triggering conditions are met, to send alarm information to preset users using a preset medium.

[0168] Therefore, in this embodiment of the application, a second preset action corresponding to the triggering rule is executed according to the triggering rule; wherein, the triggering rule specifies the monitoring item and the triggering condition; the triggering condition is specifically: the collection result of the monitoring item meets the preset condition; the second preset action uses a preset medium to send alarm information to a preset user.

[0169] The above-mentioned alarm handling based on trigger rules has the following advantages:

[0170] Real-time monitoring: By creating trigger rules, ONU performance information can be monitored in real time. Once the collected results of the monitoring items meet the preset conditions (such as the ONU's running status being offline), the server can immediately detect the anomaly or problem.

[0171] Rapid Response: Alarm information is quickly sent to preset users via preset media (such as email, SMS, instant messaging tools, etc.) to ensure that preset users can understand the problem and take action in a timely manner.

[0172] Automated processing: The automated processing of alarms reduces the need for manual monitoring, improves monitoring efficiency, and reduces the risk of missing important alarms due to human negligence.

[0173] Flexibility and customizability: Trigger rules and second preset actions can be customized according to specific monitoring needs, such as setting different trigger conditions, adjusting the severity level of alarms, and selecting different preset media.

[0174] Centralized management: Monitoring tools such as Zabbix can be used to centrally manage the monitoring and alarms of multiple ONUs, simplifying the complexity of network management and maintenance.

[0175] Historical data analysis: Alarm information and monitoring data can be recorded and stored, facilitating subsequent analysis and troubleshooting, and helping to optimize network performance and prevent future problems.

[0176] Improving network reliability: By promptly identifying and resolving potential problems, alarm mechanisms help improve the reliability and stability of PON networks and reduce the risk of service interruptions.

[0177] Cost-effectiveness: Automated alerts reduce the cost of manual monitoring, and by preventing and responding quickly to problems, they can reduce business losses caused by network failures.

[0178] In one example, the monitoring item collects the ONU's operating status. If the ONU is offline, an initial alarm can be issued to promptly investigate the problem and dispatch a repair order.

[0179] In another example, the monitored item is the interface utilization of the OLT. If the interface utilization exceeds a threshold, a second alarm can be issued. Upon receiving the second alarm, pre-defined actions can be performed. These actions may include: implementing load balancing across multiple OLT interfaces to distribute traffic across different interfaces and improve overall network performance. Pre-defined actions may also include: upgrading the interface to a higher speed interface (e.g., from GE to 10GE) to increase bandwidth capacity. Here, GE stands for Gigabit Ethernet.

[0180] In one optional embodiment of this application, the ONU's port supports camera access;

[0181] The above methods may also include:

[0182] Step C1: Save the correspondence between the ONU's port, VLAN address and the camera's MAC (Media Access Control) address;

[0183] Step C2: Collect the first MAC address of the camera connected to the first port;

[0184] Step C3: Based on the correspondence, determine whether the first MAC address matches the first port;

[0185] Step C4: If the first MAC address does not match the first port, obtain the target VLAN address that matches the first MAC address from the correspondence, and replace the VLAN address corresponding to the first port with the target VLAN address.

[0186] As mentioned earlier, the embodiments of this application are compatible with ONUs from different manufacturers. Furthermore, since the ports of the ONUs in these embodiments can support camera access, they are also compatible with cameras from different manufacturers. Since different ports can correspond to cameras from different manufacturers, isolation between cameras from different manufacturers can be achieved.

[0187] In step C1, the mapping relationship between the ONU's port, VLAN address, and the MAC address of the camera connected to that port can be recorded based on the configuration. This mapping relationship is usually stored in a database or configuration file for quick querying and updating. The configuration file mentioned above can be the configuration file of the OLT to which the ONU belongs.

[0188] In step C2, the first MAC address of the camera connected to the first port can be collected using SNMP GETNEXT and GET requests. The first port can represent any port that the camera is actually connected to.

[0189] In step C3, it can be determined whether the first port and the first MAC address exist in the above correspondence. If they do, the first MAC address matches the first port. Otherwise, if the first port and the first MAC address do not exist in the above correspondence, the first MAC address does not match the first port.

[0190] If the first MAC address and the first port do not match, the camera can be considered to have an incorrect connection. This application embodiment can detect camera connection errors in a timely manner based on the matching of the first MAC address and the first port.

[0191] Furthermore, if the first MAC address does not match the first port, a target VLAN address matching the first MAC address is obtained from the correspondence, and the VLAN address corresponding to the first port is replaced with the target VLAN address. In this way, embodiments of this application can achieve timely correction of camera access errors.

[0192] Referring to Table 3, an example of the correspondence between the port and VLAN address of the ONU and the MAC address of the camera in one embodiment of this application is shown.

[0193] Table 3

[0194] ONU ports VLAN address Camera MAC address Port 1 VLAN1 MAC1 Port 2 VLAN2 MAC2 Port 3 VLAN3 MAC3 Port 4 VLAN4 MAC4

[0195] In one example, assuming the first port is port 1, and assuming the on-site construction worker connects a camera to port 1 that should have been connected to port 4, then the MAC address of the camera connected to port 1 is specifically MAC4. Based on this correspondence, this embodiment of the application determines that port 1 and MAC4 do not match, thus enabling timely detection of incorrect camera connection issues.

[0196] Furthermore, this embodiment can also obtain the target VLAN address matching MAC4 from the correspondence: VLAN4, and replace VLAN1 corresponding to the first port with VLAN4. The correspondence after replacement is specifically: Port 1 — VLAN4 — MAC4. Therefore, this embodiment can realize timely correction of camera access errors and save the cost of on-site manual error correction.

[0197] In summary, the optical network unit monitoring method of this application embodiment, in the data acquisition network, the aggregation switch transmits VLAN broadcast between the server and the ONU, which enables the server to collect the preset performance information of the ONU through VLAN broadcast, and provides network link support for data transmission during the monitoring process of the ONU.

[0198] Secondly, the server in this embodiment automatically discovers the SN (Serial Number) of ONUs within a preset range. This automatic discovery of the ONU SN can be applied to any ONU from any manufacturer. Therefore, this embodiment can utilize the automatic discovery of the ONU SN to monitor ONUs from multiple manufacturers, thereby saving the login and search costs of network management systems from multiple manufacturers and thus improving ONU monitoring efficiency.

[0199] Furthermore, in this embodiment of the application, monitoring ONUs and monitoring items for monitoring ONUs are created based on the discovered device serial numbers, and the monitoring items are associated with the device serial numbers, which can realize the automatic collection of the collection results corresponding to the monitoring items.

[0200] Furthermore, this embodiment determines the performance information corresponding to the monitored ONU based on the collection results corresponding to the aforementioned monitoring items; it stores data records corresponding to the aggregation switch, OLT, device serial number, and performance information in the database based on the device serial number associated with the monitoring item, the OLT connected to the ONU represented by the device serial number, and the aggregation switch connected to the OLT; and it provides selection controls for dimensions such as aggregation switch, OLT, and device serial number in the data records. Thus, this embodiment allows users to filter and select ONU performance information based on dimensions such as aggregation switch, OLT, and device serial number, thereby further improving the monitoring efficiency of ONUs.

[0201] Method Example 2

[0202] This application embodiment can be applied to the monitoring project of SkyNet cameras. By interconnecting IP addresses and passing through VLANs, the network of the server, the OLT of three counties and two districts in City A, and the aggregation switch of three counties and two districts in City A are connected. Software such as Zabbix, Grafana, and database are installed on the server. The technical architecture of Zabbix+Grafana is used to collect the collection results of the monitoring items, and the corresponding performance information of the collection results is displayed through charts.

[0203] Skynet cameras are security monitoring devices primarily used for surveillance and security in public places, roads, and commercial areas. Through high-definition cameras and high-performance image processing technology, Skynet cameras can capture and record various activities in real time, providing police with clues and evidence of crimes while improving public safety.

[0204] The embodiments of this application can improve the online rate of Skynet cameras. The online rate of a camera refers to the proportion of time within a certain period of time during which the camera can work normally and transmit video signals.

[0205] In this embodiment of the application, the processing procedure on the Zabbix side specifically includes:

[0206] Step D1: Log in to the Zabbix tool, add server-side alarm triggers in Configuration - Templates, and set the upper and lower limits and levels;

[0207] Step D1 can bind an alarm template to the server. If the server experiences high CPU / memory utilization, slow disk read / write, or other issues that trigger the alarm mechanism, the alarm and its level will be displayed.

[0208] Step D2: View the monitoring dashboard;

[0209] Step D2 allows you to check if the server has triggered an alarm mechanism, such as whether disk read / write is slow or memory utilization is too high.

[0210] Step D3: View Configuration - Monitoring Items;

[0211] This step allows you to check if the collected OLT or ONU is online.

[0212] In this embodiment of the application, the processing procedure on the Grafana side specifically includes:

[0213] Step E1: Log in to the Grafana tool and select the monitoring item corresponding to ONU.

[0214] Step E2: Select the aggregation switch you want to view;

[0215] This step is used to filter the aggregation switches to which the OLT you want to view belongs.

[0216] Step E3: Select the OLT you want to view;

[0217] Step E3 selects aggregation switches that include OLTs from different manufacturers; this step is used to select the OLT that needs to be viewed.

[0218] Step E4: In each chart, query the operating status, offline reason, received optical power and other performance information of your target ONU based on the SN code or ONU index.

[0219] The ONU index is used to index the second SNMP object identifier corresponding to the monitoring item of the ONU.

[0220] Step E5: You can select all OLTs at the OLT dimension of each aggregation switch, and the interface will display the performance information of all ONUs connected to the monitoring ONUs. You can choose to export the target data records of each aggregation switch to your local computer.

[0221] This step is used to view the operating status, offline reasons, and received optical power of all ONUs connected to each aggregation switch. This allows management and maintenance personnel to obtain all parameters, quickly identify offline ONUs, and issue repair orders to different maintenance teams in different areas based on the different offline reasons.

[0222] The embodiments of this application monitor the OLT / ONU, which will bring the following beneficial effects:

[0223] 1. The embodiments of this application can realize real-time data acquisition and analysis of ONU.

[0224] This application embodiment connects the Grafana tool to the Zabbix tool to display the data through charts. It features fast data collection speed, comprehensive information, and easier distributed deployment and concurrency. It can batch and concurrently collect ONU information from different OLTs, and perform multiple automatic ONU discovery operations daily. It can collect comprehensive ONU information and update accurate ONU information in a timely manner, without requiring integration with third-party network management systems, thus eliminating vendor differences.

[0225] This application embodiment can collect ONU performance information on average once per minute. Maintenance personnel can accurately determine the offline status and offline time of the ONU based on the collection results and perform efficient processing, thereby improving the online rate of the SkyNet camera.

[0226] 2. The embodiments of this application can realize the visualization of ONU performance information.

[0227] This application utilizes Zabbix + Grafana to visualize ONU performance information. Maintenance personnel can intuitively view the data they need through Grafana and use the search function to find the online status, fault causes, and received optical power of specific OLT / ONU devices. Furthermore, government and enterprise installation and maintenance engineers, backend maintenance engineers, and SkyNet administrators can export target data tables corresponding to specific performance information of ONU devices using Grafana. For example, target data tables for specific performance information may include: target data tables for online status, target data tables for received optical power, target data tables for offline status, etc. This allows SkyNet on-site personnel to accurately dispatch work orders to the appropriate maintenance teams based on various fault causes (equipment power failure, optical signal loss, etc.).

[0228] The target data table corresponding to the received optical power can be used to determine whether packet loss in the ONU is caused by excessive optical attenuation. Optionally, the received optical power in the target data table can be matched with the received optical power range. If the received optical power in the target data table is not within the received optical power range, and packet loss is observed, the packet loss may be caused by excessive optical attenuation. In this case, corresponding measures can be taken, such as checking the fiber optic connection, replacing the fiber, and adjusting the optical power, to reduce optical attenuation and improve signal quality.

[0229] 3. The embodiments of this application employ a flexible alarm mechanism.

[0230] Zabbix offers a flexible alerting mechanism, allowing users to send alerts via email, SMS, WeChat, and DingTalk, enabling system administrators to quickly locate problems and take appropriate measures. Zabbix also provides server-side monitoring, allowing for immediate detection and handling of server-side alerts, such as those related to disk activity. Alerts can also be triggered when OLT interface usage exceeds a threshold (e.g., 60%).

[0231] 4. The embodiments of this application are compatible with ONU terminal devices from different manufacturers and cameras from different manufacturers. By configuring different VLANs to distinguish cameras in different subnets and projects, when on-site construction personnel install multiple cameras, it can detect whether the cameras are plugged into the wrong network port, collect the MAC addresses of the cameras in real time, discover problems in a timely manner, and correct camera access errors in a timely manner, thus saving the cost of on-site manual error correction.

[0232] 5. In this embodiment of the application, different scanning durations, passive and active data collection are set as needed according to the number of ONUs under different OLTs, thereby reducing server overhead and improving the integrity of the collected data.

[0233] Specifically, for OLTs with a large number of ONU devices, passive data collection can be set, with a time interval of 5-10 seconds; for OLTs with a small number of ONU devices, active data collection can be set, with a collection time of once per second. Adjustments can be made as needed to make reasonable use of bandwidth and reduce the CPU and memory overhead of the server.

[0234] 6. The embodiments of this application can perform real-time data analysis of the performance information corresponding to the collected results, and can quickly generate analysis reports and send early warnings / warnings.

[0235] 7. The embodiments of this application can present the real-time operating status, real-time received optical power, offline reasons and other performance information of each ONU through chart classification and data conversion.

[0236] Specifically, the embodiments of this application can provide an intuitive and clear interface and performance indicator display. Maintenance personnel can filter and view or export the operating status, received optical power and offline reasons of all ONUs under the corresponding aggregation switch / OLT according to the filtering conditions, so as to promptly investigate and dispatch repair orders.

[0237] 8. The embodiments of this application have strong compatibility and can be compatible with OLTs and ONUs and cameras from different manufacturers, thus reducing the maintenance cost of the equipment.

[0238] In summary, this application not only solves the problems of low online rate and untimely maintenance of SkyNet cameras, but also enables SkyNet maintenance engineers to proactively perform maintenance through the server, greatly improving user satisfaction while reducing a significant amount of ineffective manual dispatch and time costs, thus achieving "cost reduction and efficiency improvement." In other words, this application not only improves the work efficiency of SkyNet front-end and back-end maintenance engineers and SkyNet management personnel, saving substantial manual dispatch and time costs, but also enhances customer satisfaction. This application eliminates the need to wait for customers to report faults before dispatching personnel for repair; it only requires exporting the ONU device's operating status table (the target data table corresponding to the operating status) to quickly and effectively dispatch orders to maintenance teams for optical path repair and faulty equipment replacement.

[0239] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions.

[0274] Secondly, the server in this embodiment automatically discovers the SN (Serial Number) of ONUs within a preset range. This automatic discovery of the ONU SN can be applied to any ONU from any manufacturer. Therefore, this embodiment can utilize the automatic discovery of the ONU SN to monitor ONUs from multiple manufacturers, thereby saving the login and search costs of network management systems from multiple manufacturers and thus improving ONU monitoring efficiency.

[0275] Furthermore, in this embodiment of the application, monitoring ONUs and monitoring items for monitoring ONUs are created based on the discovered device serial numbers, and the monitoring items are associated with the device serial numbers, which can realize the automatic collection of the collection results corresponding to the monitoring items.

[0276] Furthermore, this embodiment determines the performance information corresponding to the monitored ONU based on the collection results corresponding to the aforementioned monitoring items; it stores data records corresponding to the aggregation switch, OLT, device serial number, and performance information in the database based on the device serial number associated with the monitoring item, the OLT connected to the ONU represented by the device serial number, and the aggregation switch connected to the OLT; and it provides selection controls for dimensions such as aggregation switch, OLT, and device serial number in the data records. Thus, this embodiment allows users to filter and select ONU performance information based on dimensions such as aggregation switch, OLT, and device serial number, thereby further improving the monitoring efficiency of ONUs.
