Technical Field

[0002] The present application relates to the field of communications, and in particular to a network link information display method, a visual network management system, and a device. Background Art

[0003] The access network in a communication network can usually include multiple different communication network lines, such as passive optical network (PON) lines and wireless fidelity (WiFi) networks. When operating or maintaining the access network, interaction between the two different networks is required to collect complete information about the access network.

[0004] However, since access networks usually use different networks, it is not easy to collect network link information, which increases the difficulty of access network operation and maintenance. Therefore, how to reduce the difficulty of access network operation and maintenance has become an urgent problem to be solved.

[0005] Summary of the Invention

[0006] The present application provides a network link information display method, a visual network management system and an apparatus for more intuitively displaying the link status in an access network.

[0007] In view of this, in a first aspect, the present application provides a network link information display method, which is applied to a communication network, wherein the communication network includes an optical network device, a gateway, and at least one terminal, the optical network device is connected to the gateway, and the at least one terminal is connected to the gateway, and the method includes:

[0008] First, connection information is obtained. The connection information can be used to indicate the connection relationship between at least one terminal and a gateway, as well as the connection relationship between an optical network device and a gateway. The gateway may specifically include a master gateway or a slave gateway in an access network. Subsequently, first link information is obtained. The first link information includes information about at least one first link between the gateway and at least one terminal, such as the link operation status or information measuring network quality. Second link information is obtained. The second link information includes information about the second link between the optical network device and the gateway, such as the online status of the device in the link, which is equivalent to classifying the links in the communication network into first links and second links. Subsequently, display information is generated based on the connection information, the first link information, and the second link information. The display information is used to display the link operation status in the communication network.

[0009] The method provided in this application can be used for segmented data collection on communication networks, especially on the link conditions in access networks in communication networks, and can display the link operation status to achieve visualization of the link quality of the access network, so that users can more intuitively observe the link operation status in the access network. For example, in a network operation and maintenance scenario, users can more intuitively observe the overall link operation status of the network through the method provided in this application, which can greatly improve the user's operation and maintenance efficiency for the network. In particular, for some scenarios involving cross-network data collection in access networks, such as an access network that includes both a PON network and a WiFi network, the method provided in this application can be used to perform segmented data collection on links of different networks, thereby realizing data collection across network devices and link operation data integration, which can be applied to access networks with more complex structures.

[0010] In one possible implementation, the method may further include: displaying the aforementioned display information. Therefore, in the implementation of the present application, after the display information is generated, the display information can be displayed on the display interface, thereby providing a more intuitive overall display of the device connection relationships in the communication network and the link operation status of each segment, allowing users to more intuitively observe the topology structure and link operation status of the communication network.

[0011] In a possible embodiment, the aforementioned generation of display information based on the connection information, the first link information and the second link information may include: judging whether there is an abnormality in at least one of the first link or the second link based on the first link information and the second link information; in the event that there is an abnormality in any of the aforementioned first links or second links, obtaining abnormality information, which may include but is not limited to one or more of the severity of the abnormality, the description of the abnormality, the handling suggestions for the abnormality, the location of the abnormality or the time of occurrence of the abnormality; and then generating display information based on the connection information and the abnormality information, which may also directly carry the first link information and the second link information, so that other link information can be displayed at the same time as the abnormality information.

[0012] In an embodiment of the present application, after collecting the first link information and the second link information, a link abnormality judgment can be performed based on the first link information and the second link information. If an abnormality exists, the abnormality is located and corresponding abnormality information is generated. Therefore, when displaying the link status, the abnormal information in the link can be displayed, thereby providing prompts for the abnormality in the link, so that users can maintain the communication network and improve the operational stability of the communication network.

[0013] In a possible implementation, the aforementioned method may further include: acquiring first historical link information, the first historical information including link information of at least one first link in a historical period, and the first historical link information may be obtained by periodically collecting the first link; acquiring second historical link information, the second historical link information including link information of a second link in the historical period, and the second historical link information may be obtained by periodically collecting the second link;

[0014] The aforementioned generating of display information based on the connection information and the abnormality information may include: combining the first historical link information, the second historical link information, the connection information, and the abnormality information to generate the display information.

[0015] In the implementation manner of the present application, link information of historical time periods in the communication network can also be collected. Therefore, when displaying the link operation status, historical information can be displayed, and changes in link operation can be displayed, so that users can make an intuitive comparison based on the displayed historical link information and the link operation status of the current time period.

[0016] In a possible embodiment, the aforementioned combination of the first historical link information, the second historical link information, the connection information and the exception information to generate the display information may include: judging whether there is a historical exception in at least one first link or the second link in the historical period based on the first historical link information and the second historical link information; and in the case that there is a historical exception in at least one first link or the second link in the historical period, obtaining historical exception information, the historical exception information including one or more of the severity of the exception, the description of the exception, the suggestion for handling the exception, the location of the exception or the time when the exception occurred; when generating the display information, the historical exception information, the connection information and the exception information may be combined to generate the display information, that is, when displaying the link operation status in the communication network, the historical exception information of the link may also be displayed at the same time.

[0017] In the implementation mode of the present application, when collecting historical link information, link anomalies in historical time periods can also be identified, so that historical anomalies of the link can be analyzed, and users can be more comprehensively informed of changes in the health status of the link, thereby more effectively optimizing or maintaining the communication network in a targeted manner.

[0018] In a possible implementation, the aforementioned first link information includes one or more of the following: status information of at least one first link or interference information in at least one first link, and the status information of at least one first link includes one or more of the following: online status, online time, offline time, or network device status during online time of a gateway;

[0020] Therefore, in the implementation manner of the present application, for the links in the communication network, the specific operating conditions of the links can be displayed in segments, so that the user can very intuitively observe the link operating conditions of each segment, and can choose to record the health of the communication network, optimize or maintain it, etc., thereby improving the stability of network operation.

[0021] In one possible implementation, the aforementioned gateway specifically includes a master gateway and a slave gateway, the master gateway being connected to at least one slave gateway via optical fiber, and the aforementioned at least one terminal being connected to either the slave gateway or the master gateway; the aforementioned at least one first link can be divided into a first sub-link and a second sub-link, the first sub-link comprising the link between the master gateway and the slave gateway, and the second sub-link comprising the link between the slave gateway and the terminal or the link between the master gateway and the terminal. Accordingly, the aforementioned first link information specifically may include link information for the first sub-link and link information for the second sub-link.

[0022] Therefore, in the implementation manner of the present application, when the gateway is set with a master gateway and a slave gateway, a finer-grained link segmentation can be performed, so that a finer-grained link operation status display can be achieved later.

Therefore, in the implementation of the present application, when generating display information, the display information can also be generated in combination with the ODN information, so that when displaying the link operation status, the ODN information can be displayed at the same time, making the display content richer and allowing users to intuitively observe the ODN information in the communication network.

In the implementation of the present application, in response to the optical network device being offline, targeted prompt information may be generated to indicate the offline state of the optical network device in a display interface.

[0030] In an embodiment of the present application, a link operation status display service can be provided to the user through the client. Specifically, display information can be generated based on the user's request and fed back to the user after the display information is generated, so that the user can observe the link operation status in the communication network more intuitively on the client.

[0077] The following will describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0078] The network link information display method and device provided in the present application can be applied to a variety of optical communication networks, including but not limited to: optical transport network (OTN), optical access network (OAN), metropolitan area network (MAN), synchronous digital hierarchy (SDH), passive optical network (PON), Gigabit PON (GPON), Ethernet passive optical network (EPON), evolved GPON (10-Gigabit-capable symmetric passive optical network, XGS-PON), Ethernet, or flexible Ethernet (FlexE), wavelength division multiplexing (WDM) network, etc., any one or more combinations thereof.

[0079] Fiber to the home (FTTH) is a fiber optic communication transmission method. The access network portion of the aforementioned optical communication network can be implemented as FTTH to achieve wider coverage. Other similar or equivalent communication transmission methods, such as fiber to the office (FTTO) and fiber to the building (FTTB), have also been proposed and can serve as application architectures for the method provided herein. The following example uses FTTH as the basis for this description.

[0080] Figure 1 is a schematic diagram of the FTTH system architecture. The optical line terminal (OLT) connects to upper-layer network-side devices (such as switches and routers) and to one or more optical distribution networks (ODNs) at the lower layer. The ODN includes a passive optical splitter for optical power distribution, a trunk fiber connected between the passive optical splitter and the OLT, and branch fibers connected between the passive optical splitter and the ONU. During downstream data transmission, the ODN transmits the downstream data from the OLT to each ONU via an optical splitter. The ONU selectively receives downstream data carrying its own identifier. During upstream data transmission, the ODN combines the optical signals sent by N ONUs into one optical signal and transmits it to the OLT. The ONU provides a user-side interface for the OAN and is also connected to the ODN. If the ONU also provides user port functions, such as an Ethernet user port or a plain old telephone service (POTS) user port, it is called an optical network terminal (ONT).

[0081] Building on FTTH, to address home Wi-Fi coverage issues, optical fiber can be extended into residents' rooms. Optical terminals providing Wi-Fi access are installed inside the rooms, shortening the distance between the user terminals and the Wi-Fi access points and improving signal quality. This application scenario is known as fiber to the room (FTTR).

[0082] Figure 2 shows a schematic diagram of the FTTR system architecture. The FTTR network and FTTH network can be viewed as a cascaded PON system. In FTTH, the OLT is deployed in the central office, while the ONU is deployed in the home's information box. The master device in the FTTR can replace the ONU in the FTTH scenario and be deployed in the home's information box. This master device in the FTTR scenario performs similar functions to the OLT in the FTTH scenario, and it can also perform similar functions to the ONU in the FTTH scenario. In other words, the master device in the FTTR combines the functions of both the OLT and the ONU, serving as a network device that connects the FTTH and FTTR networks. The slave devices in the FTTR can be deployed in each room of the home to connect to user terminals. These slave devices are essentially similar to the ONUs in the FTTH network. The slave devices in the FTTR are connected to each room, and the slave gateway can also function as an AP, enabling direct Wi-Fi connections to user terminals. User terminals (stations) can connect to the slave devices and transmit data through the Wi-Fi connections established with them.

[0083] It should be understood that multiple slave devices can be deployed in an FTTR, each connected to a corresponding downlink port on the master device. The master device can achieve unified management and configuration of all slave devices. It should be noted that the master device can also be referred to as the "master gateway," "master optical modem," or "master FTTR device," and the slave devices can also be referred to as "slave gateway," "slave optical modem," or "slave FTTR device." This application does not limit their specific names. For ease of introduction, the following text will uniformly refer to master devices and slave devices.

[0084] Combined with the architecture of Figure 2 above, in some scenarios, when the slave device in FTTR provides services to the terminal, the data transmission method of the terminal accessing the slave device may be different from the data transmission method of the devices in FTTH and FTTR. For example, communication is carried out internally through optical fiber in FTTH or FTTR, while communication between the slave device and the terminal can be carried out through a wireless network, which may include but is not limited to wireless fidelity (WiFi), near field communication (NFC), infrared, Bluetooth or ZigBee, etc.

[0085] As can be seen from the aforementioned architecture, the access network of an optical communication network can typically include different network systems. As shown in Figure 2, the PON network connects the OLT, master gateway, and slave gateway, while the network between the slave gateway and the STA may be a wireless network, such as a WiFi or Bluetooth network. Different departments typically provide operation and maintenance for different networks, so maintenance data between the two networks may not be interoperable, which complicates the overall operation and maintenance of the access network. For example, operators need to query data in the system segmentedly, querying PON line information and home network information separately, which is difficult. Existing quality assessments are based on aggregation lines and lack an end-to-end perspective for single-user evaluations. Therefore, operators cannot intuitively observe the overall quality of the access network. Furthermore, existing home network management systems do not clearly display single-user quality indicators, and different home networks may use different indicators, making maintenance even more difficult for operators.

[0086] Therefore, the present application provides a network link information display method and device, which can restore and display the user's network path across multiple types of terminals and network devices, and more intuitively display the overall link status of the access network.

[0087] The following is an introduction to the method flow provided by this application based on the aforementioned network architecture.

[0088] First, the method provided in this application can be deployed in a systematic manner. For ease of distinction, the system provided in this application can be referred to as a visual network management system. The visual network management system can be deployed in an independent computer cluster or in an existing network management system. Of course, in some possible scenarios, the visual network management system may also be deployed in a terminal, which is not limited by this application.

[0089] Referring to FIG3 , a flow chart of a method for displaying network link information provided by the present application is as follows.

[0090] 301. Get connection information.

[0091] The connection information may include information about a connection relationship between at least one terminal and a gateway, and information about a connection relationship between an optical network device and a gateway. The optical network device may specifically be a device with a management function in the aforementioned system, such as the aforementioned OLT or other device with a management function. For example, this application uses the OLT as an example for the exemplary description. The OLT mentioned below may also be replaced with other devices with a management function for the gateway, which will not be described in detail below.

[0092] Before step 301, after a terminal goes online on the gateway side or a gateway goes online on the OLT side, the OLT information, the gateway information, and the information of at least one terminal can be associated to obtain the connection information and save the connection information in the database. When step 301 is executed, the connection information can be read from the database.

[0093] The gateway may be the ONU corresponding to the aforementioned Figure 1, or the master gateway or slave gateway corresponding to the aforementioned Figure 2. The OLT, gateway, and one or more STAs in the access network may be in different networks, for example, the OLT and the gateway are in a PON network, while the gateway and the STA are in a local area network, such as a local area network formed by WiFi, Bluetooth, or infrared. In order to facilitate a more intuitive display of the overall link status of the access network in the future, the present application may associate the OLT, the gateway, and one or more STAs, such as associating the OLT with the connected ONU, and associating the ONU with the STA connected to the ONU, thereby determining the connection relationship between the OLT, the gateway, and the STA, or it can also be called a topology structure, and obtaining connection information.

[0094] In some scenarios, the gateway in the access network can be a single-layer structure or a multi-layer cascade structure. In a single-layer structure, that is, only one-layer gateway structure is set up, referring to the structure shown in Figure 1 above, the STA can directly access the ONU. In a multi-layer cascade structure, referring to Figure 2 above, the gateway referred to in the embodiment of the present application can be divided into a master gateway and a slave gateway, and the terminal can access the master gateway or the slave gateway. When the devices in the access network are associated with each other, the OLT, the master gateway, the slave gateway and the STA can be associated to form a more complete connection relationship.

[0095] Exemplarily, the specific process of associating the OLT information, the gateway information, and the at least one terminal information may include: adding information of the gateway connected to the OLT, such as the gateway identification number or name, to the OLT information; and adding information of the STA connected to the gateway, such as the STA identification number, name, or media access control (MAC) address, to the gateway information. In the case where the gateway is configured to include a master gateway and a slave gateway, information of the slave gateway connected to the master gateway, such as the slave gateway identification number or other identification information, may be added to the master gateway information; and information of the STA, such as the STA identification number, name, or MAC address, may be added to the slave gateway information.

[0096] Of course, the OLT, gateway and one or more STAs in the access network can also be associated in other ways, such as by setting a mapping table, a mapping diagram, etc. This application is only an exemplary introduction and is not intended to be limiting.

[0097] Furthermore, in one possible scenario, the visual network management system provided by the present application may further include a database (DB), which may include information about devices in each access network. For example, when each device is registered, the registration information of each device may be saved in the DB. When it is necessary to display the link status in a particular access network, information about each device in the access network, such as the name, identification number, address, and other information of each device, may be obtained from the DB.

[0098] 302. Obtain first link information between a gateway and at least one terminal.

[0099] For ease of distinction, the link between the gateway and each terminal is referred to as a first link. The number of terminals connected to the gateway may be one or more, and thus the number of first links may also be one or more.

[0100] Specifically, the first link information can be collected by the gateway and / or the terminal, such as receiving the first link information sent by the gateway and / or the terminal. The first link information may include state information or interference information when the first link performs data transmission, and can be used to indicate the operation status of the link.

[0101] Optionally, the information of the at least one first link may specifically include, but is not limited to, status information of the at least one first link or interference information in the at least one first link. The status information of the at least one first link may include, but is not limited to, one or more of the following: the online status of the gateway, the online time, the offline time, the online duration, and the offline reason. The interference information may specifically include, but is not limited to, information such as the interference duty cycle and the received optical power.

[0102] In some scenarios, referring to the access network structure of Figure 2 above, the gateway can be specifically configured to include a master gateway and a slave gateway. To achieve finer-grained monitoring of the access network's link status, the first link can be further divided into a first sub-link and a second sub-link. The first sub-link includes the link between the master gateway and the slave gateway, and the second sub-link is the link between the slave gateway and the STA or the link between the master gateway and the STA. Accordingly, the collected first link information can specifically include link information of the first sub-link and link information of the second sub-link, thereby displaying link information in the access network with finer segmentation granularity.

[0103] In addition, there may be a scenario where the gateway is offline. In this scenario, if the gateway is detected to be offline, such as when the gateway is unresponsive or the gateway reports a fault or maintenance, a first prompt message can be generated for the situation where the gateway is offline. The first link information can include the first prompt message, thereby displaying the situation of the gateway being offline.

[0104] 303. Obtain second link information between the OLT and the gateway.

[0105] For ease of distinction, the link between the OLT and the gateway is referred to as a second link, and the number of gateways connected to the OLT may be one or more.

[0106] Optionally, the second link information includes one or more of the following: status information of the second link, information on the optical power of the second link, and the status information includes online status information of the device in the second link, such as the online and offline status of the OLT or the online and offline status of other devices in the second link.

[0107] In addition, in a possible scenario where the OLT is offline, second prompt information may be generated for the situation that the OLT is offline, and the second prompt information may be used as the second link information to display the situation that the OLT is offline.

[0108] It should be noted that this application does not limit the execution order of step 302 and step 303. Step 302 can be executed first, step 303 can be executed first, or step 302 and step 303 can be executed at the same time. The specific execution order can be determined according to the actual application scenario.

[0109] In addition, the aforementioned steps 302 and 303 may be performed periodically or based on a user request.

[0110] In one scenario, the visual network management system provided by the present application can periodically perform steps 302 and 303. This can implement periodic monitoring of link conditions in the access network, allowing users to obtain timely access to link conditions in the access network, and save link information generated in the access network, allowing users to obtain historical link information in the access network.

[0111] In one possible scenario, data collection can also be performed based on user requests. The above method can also include receiving user input data, where the user input data is used to request display information of the access network. When triggered by the user input data, steps 302 and 303 can be executed. In this way, link information of the access network can be collected based on user needs, and more complete link information of the access network can be fed back to the user.

[0112] 304. Generate display information according to the connection information, the first link information, and the second link information.

[0113] After obtaining the connection information, the first link information, and the second link information, display information to be displayed can be generated. The display information may include specific content for displaying the topology between the OLT, the gateway, and one or more STAs, the specific situation of the first link, or the specific situation of the second link.

[0114] Specifically, when generating display information, a list or graph representing the topological structure between the OLT, gateway and one or more STAs can be generated based on the connection information, so that the topological structure of the access network can be displayed when the display information is displayed; using the information of the first link, it is identified whether there is an abnormality in the first link. When there is an abnormality, the display content for the first link is generated based on the information of the abnormal point and the first link information. When there is no abnormality, the display content for the first link can be generated directly based on the first link information; using the second link information, it is identified whether there is an abnormality in the second link. When there is an abnormality, the display content for the second link is generated based on the information of the abnormal point and the second link information. When there is no abnormality, the display content for the second link can be generated directly based on the second link information.

[0115] 305. Display information.

[0116] After the display information is generated, it can be displayed on the display terminal. The display information can be used to represent the connection relationship between various devices in the access network and the link operation status information between various devices, so that the user can more intuitively observe the link operation status in the access network on the display interface. Even if the access network includes different types of networks, the user can still more intuitively observe the link operation status of the access network.

[0117] Among them, step 305 is an optional step. The display information can be displayed in the visual network management system provided by this application, or it can be sent to the user client and displayed by the user through other display devices. This application does not limit this.

[0118] Specifically, the displayed information may include but is not limited to: one or more of the aforementioned connection information, information included in the first link information, information included in the second link information, information included in the first historical link information, information included in the second historical link information, or abnormal information.

[0119] For example, the topology between the OLT, gateway, and STA can be displayed in the display interface. In the topology, the first link and the second link can be represented by connecting lines, and the first link information can be displayed near the first link, and the second link information can be displayed near the second link. When there is an abnormal point, the abnormal point can be highlighted in the display interface, such as marking the location of the abnormal point in the topology structure, highlighting the abnormality of a certain indicator, etc.

[0120] Therefore, in the implementation manner of the present application, the OLT, gateway and one or more STAs are associated, so that the overall connection relationship between the OLT, gateway and one or more STAs can be more intuitively displayed; at the same time, based on the overall connection relationship, the specific situation of each segmented link can be displayed, thereby providing a more intuitive and complete display of the link situation of the access network.

[0121] In addition, when generating display information, abnormality diagnosis can also be performed on the first link and / or the second link. It can be determined whether there is an abnormality in at least one of the first link or the second link based on the first link information and the second link information; if there is an abnormality in at least one of the first link or the second link, the abnormality information is obtained; and display information is generated based on the connection information and the abnormality information. Therefore, in the embodiment of the present application, link abnormality diagnosis can be performed based on the collected information of the first link and the information of the second link, so as to identify the link abnormality, so that the link abnormality in the access network can be displayed, and the link abnormality display between devices across different networks can be realized.

[0122] In one possible scenario, display information can also be generated in combination with historical link information. For example, historical link information of at least one first link in a historical period can be obtained, referred to as first historical link information for ease of distinction; and historical link information of a second link in a historical period can be obtained, referred to as second historical link information for ease of distinction; and the display information can be generated by combining the first historical link information, the second historical link information, and the exception information.

[0123] Specifically, the first historical link information and the second historical link information can be used to determine whether an anomaly exists in at least one of the first links or the second link during a historical period; if an anomaly exists in at least one of the first links or the second link during a historical period, the historical anomaly information is obtained; and the display information is generated by combining the historical anomaly information and the historical information. Therefore, in the embodiments of the present application, when generating the display information, the display information is also generated in combination with the historical anomaly information, that is, the historical anomalies of the access network are displayed, so that when the user makes a judgment on an anomaly in the access network, the historical anomaly can be combined to achieve de-jittering of the current anomaly judgment, thereby improving the accuracy of the current anomaly judgment.

[0124] In order to further enrich the displayed information, more device information can be displayed when generating the display information, so that the user can observe the operation status of the access network more comprehensively.

[0125] In a possible embodiment, the aforementioned method may further include: obtaining information of the optical distribution network ODN, the ODN information including the number of neighboring gateways of the gateway or the error information of the ODN port, etc. When generating display information, the display information can be generated in combination with the ODN information, so that when displaying the specific information of the access network, the ODN information can be displayed, so that the user can observe the operation status of the ODN in the access network.

[0126] In one possible implementation, the method may further include: obtaining information about at least one terminal; and including the information about the at least one terminal in the displayed information. Therefore, when displaying the displayed information, specific information about the terminals connected to the network may be displayed, allowing users to intuitively observe the specific information about the terminals connected to the network.

[0127] Furthermore, the method provided in this application is introduced in more detail below in combination with the system architecture provided in this application.

[0128] For example, the visual network management system provided by the present application can be divided into different modules. The specific structure and application scenarios of the visual network management system provided by the present application are introduced below.

[0129] Refer to FIG4 , which is a schematic diagram of an application scenario provided by the present application.

[0130] In this application, the link to the access network is exemplarily divided into three segments, as shown in Figure 4, Access 1, Access 2, and Access 3. Access 1 is the link between the OLT and the master gateway, Access 2 is the link between the master gateway and the slave gateway, and Access 3 is the link between the slave gateway and the STA.

[0131] Of course, the specific link segment can also be replaced with two or more segments, such as merging the aforementioned access segment 2 with the access segment 3, or performing more link segments based on other nodes in the access network, etc. This application does not list them all.

[0132] The visual network management system 40 provided in this application can be divided into multiple modules, such as the end-to-end display module 44, the end-to-end processing module 43, the PON acquisition module 42, and the terminal acquisition module 41 shown in Figure 4. Among them, the access end-to-end display module 44 is an optional module.

[0133] The terminal collection module 41 may be used to collect link information of access segment 2 and access segment 3. Specifically, it may be used to execute the steps in the aforementioned step 303.

[0134] The PON collection module 42 may be used to collect link information of access segment 1. Specifically, the steps in the aforementioned step 303 may be performed.

[0135] The end-to-end processing module 43 may be configured to process the collected link information of access segment 1, access segment 2, and access segment 3, and generate display information that may be displayed.

[0136] The end-to-end display module 44 may be configured to display the display information output by the end-to-end processing module 43 .

[0137] Optionally, the end-to-end display module 44 can be deployed in the form of a client. It can be understood that in this case, the visual network management system provided by the present application can be divided into a server and a client. The server can include the aforementioned end-to-end processing module 43, PON acquisition module 42, and terminal acquisition module 41, and the client can include the end-to-end display module 44.

[0138] Therefore, in the implementation manner of the present application, the visual network management system provided by the present application can be used to collect link information between different nodes of the access network, thereby displaying the link status of the access network across the network.

[0139] Furthermore, the execution steps of each module in the visual network management system provided by the present application can be shown in Figure 5.

[0140] The user input may include but is not limited to: user identification, serial number (SN), Ethernet point-to-point protocol (PPPoE) account, alias and other information.

[0141] End-to-end display module 44: receives user input and sends a request to the background processing module, that is, the end-to-end processing module, to find the user information and the associated network path, and obtain the diagnosis result information of the end-to-end processing module 43 for display.

[0142] End-to-end processing module 43: can be used to perform end-to-end resource association processing based on the data obtained from DB 45, that is, to associate the OLT, main gateway and STA; perform on-demand diagnosis based on user requests and information collected by PON acquisition module 42 and terminal acquisition module 41; and return the user's diagnosis results.

[0143] The PON collection module 42 collects the operation information of the PON link on the OLT side and uploads it to the end-to-end processing module 43 .

[0144] The terminal collection module 41 collects the operation information of the WiFi network on the terminal side and / or the operation information of the STA, and uploads it to the end-to-end processing module 43 .

[0145] DB 45: stores information about each device connected to the network, such as the device's identification, port number, or port number.

[0146] The following further introduces the network link information display method provided by this application in combination with the various modules in the visual network management system provided by this application and specific application scenarios.

[0147] The method provided in this application can be divided into multiple stages or application scenarios. For example, the multiple stages may include an end-to-end resource association stage and an access network quality query stage. The application scenario may include a scenario of querying access network quality in combination with historical information or a scenario of querying device offline access network quality.

[0148] 1. End-to-end resource association stage

[0149] 6 , a flow chart of another method for displaying network link information provided by the present application is as follows.

[0150] 601. The ONU powers on the OLT.

[0151] The ONU can include either the aforementioned master gateway or the aforementioned slave gateway. After the ONU is connected to the OLT, for example, the master ONU can be connected to the OLT via optical fiber and powered on. The ONU can receive PON operating parameters from the OLT and determine its own operating parameters based on the received PON operating parameters, such as the transmit optical power level or ONU identification. The OLT can receive information sent by the ONU, such as the ONU name, serial number, and number of ports, and establish a management channel between the OLT and the ONU.

[0152] 602. The OLT notifies the end-to-end processing module that the ONU is online.

[0153] After the ONU is registered on the OLT side, the OLT can notify the end-to-end processing module that the ONU has come online. The OLT can include ONU information in the notification message sent to the end-to-end processing module, such as the ONU serial number, name, or port number connected to the OLT.

[0154] 603. The end-to-end processing module performs ONU registration.

[0155] The end-to-end processing module then registers the ONU based on the notification information sent by the OLT. A communication channel can be established between the end-to-end processing module and the ONU to facilitate subsequent data collection.

[0156] 604. The end-to-end processing module performs ONU resource normalization processing.

[0157] After the ONU is registered, the end-to-end processing module normalizes the registered ONU resources, such as unifying the dimensions of the resources of each ONU, so that the end-to-end processing module can perform unified scheduling on the registered ONUs.

[0158] 605. The STA goes online on the gateway side, and the gateway side caches the STA information.

[0159] After establishing a connection with the gateway, the STA can send STA information to the gateway, and the gateway can allocate available wireless resources to the STA.

[0160] The gateway side can cache the information of online STAs and their corresponding wireless resources.

[0161] 606. The end-to-end processing module searches for STA resources on the gateway.

[0162] The end-to-end processing module may request a STA resource retrieval request from the gateway, ie, obtain information about the STAs connected to the gateway from the gateway, such as the number of STAs connected to the gateway, STA identifiers, MAC addresses of the STAs, and other information.

[0163] If an AP is set between the gateway and the STA, the STA can register with the gateway through the AP, and the end-to-end processing module can obtain information about the accessed AP and information about the STAs accessing each AP from the gateway.

[0164] 607. The end-to-end processing module associates the OLT, gateway, and STA.

[0165] The end-to-end processing module may associate the OLT, the gateway, and the STA based on the stored information of the registered devices, that is, store the connection relationship between the OLT, the gateway, and the STA.

[0166] 608. The end-to-end processing module stores the connection relationship between the OLT, gateway, and STA in the DB.

[0167] After the end-to-end processing module establishes the connection relationship among the OLT, the gateway, and the STA, the connection relationship may be sent to the DB so as to be stored in the DB.

[0168] The connection relationship between the OLT, gateway and STA can be specifically represented by a connection relationship table, or by adding the information of the next-level device to the saved information of each device. The specific information can be determined according to the actual application scenario.

[0169] In the implementation of this application, during the end-to-end resource association phase, the OLT, gateway, and STA can be associated to determine the connection relationship between the OLT, gateway, and STA, achieving end-to-end resource association across networks. This provides a more complete device topology for displaying cross-network links within the access network. By utilizing the registration mechanism for online devices within the access network, end-to-end device association is achieved, eliminating the need to manually query gateway operating information across different systems using different names, thereby improving query efficiency.

[0170] 2. Access Network Quality Query Phase

[0171] Referring to FIG. 7 , a flow chart of another method for displaying network link information provided by the present application is as follows.

[0172] 701. The user inputs data in the end-to-end presentation module.

[0173] The end-to-end display module can be deployed in the form of a client. For example, a user can log in to the client through a browser on a terminal and enter input data for querying the end-to-end display information on the client's display interface. The input data can specifically include information such as user ID, SN, PPPoE account or alias.

[0174] In addition, users can request to display the overall link status of the access network in the end-to-end display module, or they can request to display the link status between a specific terminal and the OLT. For example, when a user requests the link status of a specific STA in the access network, they can include the STA's information, such as the STA's name, identifier, or MAC address, to request to display the status of the link corresponding to the STA.

[0175] 702. The end-to-end display module requests access network quality from the end-to-end processing module.

[0176] After receiving the user's input data, the end-to-end display module may send a request message to the end-to-end processing module to request the end-to-end processing module for access network quality.

[0177] 703. The end-to-end processing module obtains connection information of devices in the access network from the DB.

[0178] After receiving the request message from the end-to-end display module, the end-to-end processing module can obtain the connection information of the device in the access network corresponding to the request message from the DB.

[0179] 704. The PON acquisition module obtains link information on the OLT side from the OLT.

[0180] The PON acquisition module, triggered by the end-to-end processing module, can obtain link information between the OLT and the gateway, namely the aforementioned first link information, from the OLT. This information can include online and offline status information or optical power information. The online and offline status information can include information such as the OLT's online status, online time, offline time, online duration, or PON port number. The optical power information can specifically include, but is not limited to, information such as the optical power received by the OLT from the main gateway and the optical power transmitted by the OLT.

[0181] Optionally, the PON acquisition module can also collect information about the ODN network, such as the number of neighboring gateways of each gateway, and the error conditions of the ODN ports under the PON ports, such as forward error correction (FEC) errors or bit interleaved parity (BIP) errors.

[0182] 705. The terminal acquisition module obtains the gateway side link information.

[0183] The terminal acquisition module obtains the gateway side link information, i.e., the aforementioned second link information, under the triggering of the end-to-end processing module. For example, if the gateway and STA are connected via a WiFi network, the terminal acquisition module can collect WiFi link interference information or WiFi link status information.

[0184] The interference information may include, but is not limited to, information for measuring interference conditions of a WiFi link, such as an interference duty cycle or a WiFi received signal strength indication (RSSI).

[0185] The status information of the WiFi link may include, but is not limited to, one or more of the following information: gateway online status, online time, online duration, offline time, offline reason, or whether WiFi is turned on.

[0186] The gateway side link information may also include information such as the gateway's received optical power, device memory occupancy rate, or CPU occupancy rate.

[0187] 706. The end-to-end processing module queries STA information through the gateway.

[0188] Optionally, the end-to-end processing module queries STA information through the gateway. The STA information may include but is not limited to the STA's online status, online time on the gateway, online duration, signal strength, or MAC address.

[0189] 707. The end-to-end processing module determines whether an abnormality exists, and identifies abnormal information if an abnormality exists.

[0190] After collecting the link information of the OLT link (i.e., the first link information) and / or the link information of the WiFi link (i.e., the second link information), the end-to-end processing module can determine whether there is an abnormality in the OLT side link and / or the WiFi link, and if an abnormality exists, it will display the specific information of the abnormality, i.e., there is abnormal information. Subsequently, the link information of the OLT link, the link information of the WiFi link, and the abnormal information can be sent as display information to the end-to-end display module, so that the specific information of the generated abnormality can be displayed during subsequent display.

[0191] In the absence of anomalies, the end-to-end processing module can generate display information based on the link information of the OLT link and the link information of the WiFi link, so that the user end-to-end module can display the specific situation of the link.

[0192] Specifically, for the OLT side link, the end-to-end processing module can determine whether there is an abnormality in the OLT side link, that is, the second link between the OLT and the gateway, based on the link information on the OLT side, such as the OLT is offline, the OLT online time is shorter than the preset online time, etc. If there is an abnormality, abnormal information for the OLT side link is generated, such as the location of the abnormal point in the access network, the abnormality type, and other information.

[0193] For the gateway link, the end-to-end processing module can determine whether there is an anomaly in the WiFi link based on the WiFi link interference information or WiFi status information collected by the terminal collection module. Examples of anomaly conditions include the gateway being offline, the interference duty cycle exceeding a preset duty cycle, or the signal strength falling below a preset strength value. If an anomaly is detected, anomaly information is generated.

[0194] 708. The end-to-end display module displays end-to-end information.

[0195] After receiving the display information from the end-to-end processing module, the end-to-end display module can display the display information.

[0196] The display information may specifically include one or more of connection information between devices, link information on the OLT side, link information on the gateway side, STA information, or ODN network information.

[0197] For example, the display interface in the method provided in this application may be as shown in FIG8 , wherein the content displayed in the display interface may specifically include:

[0198] The connection relationship between the terminal, slave gateway, master gateway, ODN and OLT is specifically represented by the icons of each device in the display interface through connecting lines;

[0199] Information about each device in the access network and specific information about the link may include:

[0200] Terminal information may include: terminal MAC address, online status, online duration, signal strength or number of times the signal is poor, etc.

[0201] The information from the gateway can be divided into multiple modules:

[0202] Basic device information includes: MAC address, model, version number, and uplink mode, i.e., upload transmission method;

[0203] Status information may include: the gateway's online status, online duration, last offline time, last offline reason, and WiFi status;

[0204] WiFi interference information can include: received optical power, CPU or memory usage, interference duty cycle, or negotiated rate.

[0205] It can also include the number of device restarts or the number of terminal connection limits exceeded.

[0206] The main gateway information can also be divided into multiple modules:

[0207] Basic device information may include: the online status of the main gateway, online duration, the last offline time, the last offline reason, and WiFi status;

[0208] Status information may include: the online status of the primary gateway, online duration, last offline time, last offline reason, and WiFi status;

[0209] WiFi interference information can include: received optical power, CPU or memory occupancy, or interference duty cycle;

[0210] It can also include the number of device restarts or the number of terminal connection limits exceeded.

[0211] ODN information may include:

[0212] Basic ODN information, including the number of gateways connected to the PON port or the number of weak optical fibers;

[0213] ODN error information may include FEC corrected error codes, FEC uncorrected error codes, or BIP error codes;

[0214] OLT information includes:

[0215] Basic device information: OLT IP address, port number or online status, etc.

[0216] OLT optical power information, including: OLT receiving main gateway optical power, OLT transmit optical power, Ethernet interface (i.e., Ethernet 0 / 9 / 3 shown in Figure 8), and uplink port maximum bandwidth utilization;

[0217] It can also include the number of times the bandwidth utilization exceeds the limit, etc.

[0218] Possible anomalies can be indicated in a variety of ways, such as displaying the identified anomaly information in the pending fault column, or highlighting the anomaly item in the link specific information under the device topology relationship, such as highlighting the anomaly item, abnormal device or abnormal link.

[0219] In addition, it should be noted that the content displayed in the display interface in the method provided by this application may include more or less content compared to the aforementioned Figure 8, or its combination and arrangement method can be adjusted according to the actual application scenario. The specific content can be determined based on the actual application scenario, and this application does not limit this.

[0220] In the embodiments of this application, the link operation status of each segment of the access network can be displayed. The link quality of each access segment can be visualized, which can more intuitively display the user's access segment quality and improve the effectiveness of link quality queries. Furthermore, the status information of key components of the access network segment can be visually displayed in a differentiated manner, more intuitively showing abnormal components and achieving better diagnosis of abnormal devices.

[0221] 3. Querying Access Network Quality Scenarios Based on Historical Information

[0222] Referring to FIG9 , a flow chart of another method for displaying network link information provided by the present application is as follows.

[0223] 901. The PON collection module periodically collects link operation information on the OLT side.

[0224] 902. The terminal collection module periodically collects WiFi link operation information.

[0225] Among them, step 901 and step 902 are similar to the aforementioned step 704 and step 705, and the similarities are not repeated here.

[0226] The difference is that during the operation of the access network, the PON acquisition module and the terminal acquisition module can periodically collect data and save the collected data in the DB to monitor the operating status of the access network, making it easier to trace the historical operating status of the access network.

[0227] 903. The user inputs data in the end-to-end presentation module.

[0228] 904. The end-to-end display module requests access network quality from the end-to-end processing module.

[0229] 905. The end-to-end processing module obtains connection information of devices in the access network from the DB.

[0230] 906. The PON acquisition module obtains link information on the OLT side from the OLT.

[0231] 907. The end-to-end processing module obtains gateway-side link information.

[0232] 908. The end-to-end processing module queries STA information through the gateway.

[0233] Among them, steps 903 to 908 can refer to the description of steps 701 to 706 above, and will not be repeated here.

[0234] 909. The end-to-end processing module obtains the OLT side link information and the WiFi side link information of the historical period.

[0235] In the embodiment of the present application, since the PON acquisition module and the terminal acquisition module periodically collect data and save it in the DB, when end-to-end display is required, the link information of the historical period can be extracted from the DB to trace back whether there are any abnormalities in the link operation in the historical period, and to improve the accuracy of abnormality diagnosis in the current period.

[0236] 910. The end-to-end processing module determines whether an abnormality exists, and identifies abnormal information if an abnormality exists.

[0237] The description of step 910 can refer to the description of step 707 above, and the similarities are not repeated here. The difference is that when the end-to-end processing module determines whether an anomaly exists, it can also identify anomalies in the historical period and generate historical anomaly information if an anomaly exists in the historical period.

[0238] Specifically, the end-to-end processing module can obtain the number of anomalies or the specific values ​​of anomaly items from historical link information, and can then calculate historical anomalies to generate historical anomaly information. For example, referring to Figure 8 above, the terminal's signal difference parameters, the number of device restarts between the slave gateway and the master gateway, the number of terminal connection limit violations, or the number of times the OLT's bandwidth utilization exceeds the limit can be calculated to display the historical anomalies of each device in the access network, allowing users to more accurately diagnose the device's operating status.

[0239] 911. The end-to-end display module displays end-to-end information.

[0240] Compared with the aforementioned step 708, the content to be displayed in step 911 is increased with link information of the historical period. In the case that there is an abnormality in the link during the historical period, the abnormality information in the historical period is also displayed.

[0241] Therefore, in the implementation manner of the present application, the link information of the historical period of the access network can be displayed, which makes it easier for users to trace the historical link operation status of the access network and achieve the effect of abnormal diagnosis and de-jittering.

[0242] 4. Device offline access network quality query scenario

[0243] Typically, devices connected to the network may be offline, such as due to device failure or device shutdown, which may cause the data collection module to be unable to collect information about the offline devices. In an embodiment of the present application, the data collection step for offline devices can be skipped to adapt to the scenario where the device is offline.

[0244] Taking the scenario where the OLT is offline as an example, referring to FIG10 , a flow chart of another method for displaying network link information provided by the present application is as follows.

[0245] 1001. The PON collection module periodically collects OLT-side link operation information.

[0246] 1002. The terminal collection module periodically collects WiFi link operation information.

[0247] 1003. The user inputs data in the end-to-end presentation module.

[0248] 1004. The end-to-end display module requests access network quality from the end-to-end processing module.

[0249] 1005. The end-to-end processing module obtains connection information of devices connected to the network from the DB.

[0250] Among them, steps 1001 to 1005 can refer to the description of the aforementioned steps 801 to 805, which will not be repeated here.

[0251] 1006. The PON collection module skips link information collection on the OLT side.

[0252] In the scenario where the OLT is offline, the PON acquisition module may not be able to collect information about the OLT side link, so the step of collecting OLT link information can be skipped.

[0253] Optionally, a prompt message indicating that the OLT is in an offline state may be generated so that the offline state of the OLT can be displayed in step 1011. For example, referring to FIG. 8 , when the OLT is determined to be in an offline state, the "online state" item may be set to "offline." For information such as optical power that cannot be collected, historical information may be displayed, or targeted prompt messages may be displayed, such as "no data collected" or set to blank.

[0254] 1007. The end-to-end processing module obtains gateway side link information.

[0255] 1008. The end-to-end processing module queries STA information through the gateway.

[0256] 1009. The end-to-end processing module obtains OLT-side link information and WiFi-side link information in a historical period.

[0257] 1010. The end-to-end processing module determines whether an abnormality exists, and identifies abnormal information if an abnormality exists.

[0258] 1011. The end-to-end display module displays end-to-end information.

[0259] Among them, step 1007 is similar to step 1011 and will not be repeated here.

[0260] Therefore, in the implementation manner of the present application, for the scenario where the device is offline, the link information collection of the offline device can be skipped to be applicable to more scenarios.

[0261] In addition to the OLT being offline, other devices may also be offline, such as the gateway being offline, the AP being offline, etc. Accordingly, the collection of link information related to the offline devices can be skipped to adapt to the scenario where the devices are offline.
