Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an optical line terminal cutover method and device, an electronic device, and a computer-readable storage medium. Background Art

[0002] During access network equipment maintenance, equipment upgrades, network optimization, and other reasons often require a cutover of one or more PON (Passive Optical Network) ports of an OLT (Optical Line Termination), or even the entire OLT device, to update the physical link and transfer the device configuration. The cutover tools currently provided by mainstream network management vendors support the cutover of a single PON port across OLT device vendors (e.g., between a single PON port from vendor A and a single PON port from vendor B), but do not support the cutover of multiple PON ports or the entire OLT device. Cutover tools provided by OLT device vendors support the cutover of multiple PON ports or the entire device, but do not support the cutover of devices across different vendors and models.

[0003] In the prior art, there is no tool for cross-vendor whole-device cutover. Cross-vendor whole-ODT device cutover can only be done manually, which is labor-intensive, inefficient, and prone to errors. Summary of the Invention

[0074] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. 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.

[0075] Cutover of an OLT involves transferring the configuration of its physical links. The complete cutover process includes initiating the cutover, creating a data configuration script, distributing the configuration script, changing the physical links, confirming services, and modifying resources. Traditionally, creating and distributing cutover data configuration scripts is a manual process, which is time-consuming, inefficient, and prone to errors. For example, most industry cutover tools use network management interfaces (such as the TL1 northbound interface) to distribute configuration information to devices one by one through commands. Traditional cutover methods can be time-consuming. For example, when performing an entire cutover of an OLT serving 2,000 users, distributing the configuration script can take approximately four hours.

[0076] An embodiment of the present application provides an optical line terminal cutover method. A PON port cutover correspondence is pre-generated based on cutover service requirements for the original optical line terminal when the original optical line terminal is cutover to a destination optical line terminal. A computer program is then executed to generate a target configuration file suitable for the destination optical line terminal based on configuration data of the original optical line terminal and information such as the manufacturer and model of the destination optical line terminal. The configuration file is then imported to configure the destination optical line terminal based on the target configuration file automatically generated by the program. For business scenarios in which the entire optical line terminal is cutovered, this method can greatly improve the configuration efficiency of the optical line terminal, thereby shortening the cutover time for the entire device.

[0077] The following describes the specific implementation of the optical line terminal cutover method disclosed in the embodiment of the present application with examples.

[0078] like Figure 1 As shown, an optical line terminal cutover method disclosed in an embodiment of the present application includes: steps 110 to 160.

[0079] Step 110: Obtain the global configuration file of the original optical line terminal.

[0080] The configuration file of the optical line terminal is used to configure the operating parameters of each module in the optical line terminal. After the configuration file is imported into the optical line terminal, the optical line terminal will initialize each module based on the configuration data configured in the configuration file to operate based on the operating parameters set by the configuration data in the configuration file.

[0081] Different manufacturers and models of optical line terminals have certain requirements for the format and content of the configuration data included in the configuration file. For details, please refer to the configuration documentation of the corresponding model of equipment.

[0082] When an optical line terminal is connected to the network management system, maintenance personnel first send the created configuration file to the optical line terminal via commands or other means. The optical line terminal initializes each module based on the configuration data in the received configuration file and begins operation. Typically, the network management system stores the configuration data for each optical line terminal.

[0083] In an embodiment of the present application, a global configuration file for a specified optical line terminal can be exported through a network management system. The global configuration file includes configuration data for the following sections: pre-configuration, general configuration, VLAN configuration, GPON port configuration, service port configuration, and multicast configuration. Each section of configuration data describes the corresponding configuration item in a pre-set text format. For example, the GPON port configuration module describes configuration items such as the PON port's board number, slot number, port number, and speed.

[0084] Step 120: Acquire a PON port cutover correspondence relationship when the original optical line terminal is cutover to the destination optical line terminal.

[0085] Next, a PON port cutover correspondence relationship when the original optical line terminal is cutover to the destination optical line terminal is obtained.

[0086] In an embodiment of the present application, the PON port cutover correspondence is generated based on the port correspondence before and after the cutover planned on site. Among them, the PON port cutover correspondence includes: the correspondence between each port under the management IP of the original optical line terminal and each port under the management IP of the destination optical line terminal. In some embodiments of the present application, the ports in the PON port cutover correspondence can be represented by the management IP of the optical line terminal, as well as the board number, slot number and port number of the optical line terminal. The PON port cutover correspondence also includes: port type. Currently, there are mainly two types of port types: GPON and EPON, which need to be clarified during cutover. The port type is used to indicate the instruction logic used when translating the configuration file. Different port types have different instruction logics.

[0087] Step 130: Generate PON port configuration data of the destination optical line terminal according to the PON port configuration data in the global configuration file and the PON port cutover correspondence.

[0088] In some embodiments of the present application, the global configuration file can be parsed based on the configuration data format, port naming rules, and other configuration file generation rules in the configuration file of the original optical line terminal to obtain the relevant content of the global configuration file for configuring the PON port. Subsequently, based on the PON port cutover correspondence, the relevant content of the global configuration file for configuring the PON port of the original optical line terminal is converted into content for configuring the corresponding PON port of the destination optical line terminal in accordance with the configuration data format and port naming rules required by the destination optical line terminal, thereby obtaining the PON port configuration data of the destination optical line terminal.

[0089] Step 140: Concatenate the PON port configuration data of the destination optical line terminal with the general configuration data of the destination optical line terminal to obtain a target configuration file.

[0090] In addition to PON port configuration data, the global configuration file of the optical line terminal also includes: pre-configuration data (i.e., pre-configuration data), general configuration data (i.e., global-config), VLAN configuration data (i.e., vlan-config), service port configuration data (i.e., bbs-config), platform configuration data (i.e., platform-config), etc. During an OLT device cutover, the destination optical line terminal (i.e., the new OLT) has all parameters pre-configured except for global-config. Therefore, only the changed parts need to be updated, that is, only the general configuration data and PON port configuration need to be updated. In some embodiments of the present application, the general configuration data may include: rate template and service template information.

[0091] After obtaining the PON port configuration data of the destination optical line terminal, the pre-generated universal configuration data of the destination optical line terminal is spliced ​​with the PON port configuration data of the destination optical line terminal according to the configuration file format required by the destination optical line terminal to obtain a target configuration file for importing into the destination optical line terminal.

[0092] Step 150: Import the target configuration file into the destination optical line terminal.

[0093] In some embodiments of the present application, the target configuration file obtained in the above steps can be imported into the destination optical line terminal using the configuration file import function of the network management system. For example, the target configuration file can be a startrun.dat file generated according to the configuration file format required by the manufacturer of the destination optical line terminal. After selecting the startrun.dat file in the network management system, the configuration file import command is executed through the network management system to import the configuration file into the designated optical line terminal.

[0094] Step 160: Restart the destination optical line terminal so that the target configuration file takes effect on the restarted destination optical line terminal.

[0095] After importing the target configuration file into the destination optical line terminal, the destination optical line terminal can be manually restarted or restarted via a remote command. After the destination optical line terminal is restarted, it will initialize each functional module using the locally stored configuration file. After the initialization is completed, the target configuration file will take effect on the restarted destination optical line terminal.

[0096] After testing, it was found that the process from importing the target configuration file into the destination optical line terminal to restarting the destination optical line terminal and completing initialization typically takes about 20 minutes. In contrast, using the traditional method of cutting over the entire optical line terminal, which requires several hours to cut over configuration data piece by piece, the optical line terminal cutover method disclosed in the embodiments of the present application significantly improves the cutover efficiency of the entire optical line terminal.

[0097] like Figure 2 As shown, in some embodiments of the present application, before the step of importing the target configuration file into the destination optical line terminal, the step further includes: step 141.

[0098] Step 141: Acquire the working status information of the optical network unit of the original optical line terminal before cutover.

[0099] The optical network unit working status information includes: port information corresponding to the optical network unit, the optical network unit management status and the number of online MAC (Media Access Control Address) addresses matched by the optical network unit.

[0100] Before the cutover begins, it is necessary to collect the management status and MAC address online information of the user's ONU (Optical Network Unit) before the cutover.

[0101] In some embodiments of the present application, a pre-generated service confirmation program can be executed to collect the ONU (i.e., optical network unit) management status and MAC address online information before the cutover, and then the port information corresponding to the ONU, as well as the collected management status and MAC address online information, are used together as the ONU working status information. The port information corresponding to the ONU includes: the management IP address of the OLT to which the optical network unit (i.e., ONU) is connected, the board number, slot number, and port number of the optical network unit in the OLT; the optical network unit management status is used to indicate whether the corresponding ONU is online or offline; and the MAC address online information is used to indicate the number of MAC addresses online.

[0102] In some embodiments of the present application, before executing the service confirmation procedure, it is first necessary to select the manufacturer and model of the original optical line terminal (i.e., the OLT to be cutover), and then execute the service confirmation procedure matching the selected original optical line terminal to collect the optical network unit management status and the number of MAC addresses online that match the optical network unit under the original optical line terminal as the working status information of the optical network unit before cutover.

[0103] In some embodiments of the present application, the working status information of the optical network unit is obtained by the following method: running a service confirmation program that matches the current optical line terminal to obtain the optical network unit management status of the optical network unit under each port of the optical line terminal, and the number of online MAC addresses matched by the optical network unit, and obtaining the optical network unit working status information based on the optical network unit management status and the number of online MAC addresses, as well as the port information corresponding to the optical network unit; wherein, the service confirmation program automatically discovers the optical network unit under the port of the optical line terminal by executing an optical network unit query instruction, and obtains the optical network unit management status of the optical network unit matched by the optical network unit under the optical line terminal; the service confirmation program obtains the MAC address list under the port of the optical line terminal by executing a port MAC address query instruction, and obtains the number of online MAC addresses matched by the optical network unit under the optical line terminal based on the obtained MAC address list.

[0104] In some embodiments of the present application, the service confirmation program is an online execution script, that is, the program needs to be run in a secure and isolated network that can log in to the network management device. The service confirmation program is pre-installed with an optical network unit query instruction and a port MAC address query instruction that match the manufacturer and model of the matching original optical line terminal. During the execution of the service confirmation program, the online ONU (i.e., optical network unit) of the specified port under the original optical line terminal can be automatically discovered by executing the optical network unit query instruction, and the number of online MAC addresses of the specified port (i.e., specified ONU) can be obtained by executing the port MAC address query instruction.

[0105] For example, when querying the ONU status of a certain port, the optical network unit query instruction can be: dispayont info 0 1 2all. There are two ONU states: online and offline. Online means that the ONU is automatically discovered by the OLT, and offline means that the ONU is not detected. The automatically discovered ONU will be managed by the OLT, and it can be considered that the ONU is in an online state. In some embodiments of the present application, the collected ONU management status information can be recorded in a file, and each line of text in the file describes the port information of a port and the status of the ONU on the port. For example, "106.5.1.14 1 / 2 / 1:2 online" means that the OLT management IP is 106.5.1.14, the PON port number is: board 1, slot 2, port 1, and the ONU numbered 2 is online.

[0106] For another example, when querying the MAC address online status of a specified port, the port MAC address query instruction can be: display mac-address port 0 / 1 / 2all. In some embodiments of the present application, the collected MAC address online information can be recorded in a file, with each line of text in the file describing the number of MAC addresses online for a specified number of ONUs on a port. For example, "#106.5.1.14!1 / 2 / 1:2@2!" indicates that the OLT management IP is 106.5.1.14, the PON port number is: board 1, slot 2, port 1, and ONU number 2 has two MAC addresses online.

[0107] By executing the above optical network unit query command, online ONUs that can access the OLT port may be automatically discovered and thus managed by the OLT. Therefore, in this way, online ONUs connected to the port under the OLT (i.e., automatically discovered ONUs) can be obtained. Furthermore, based on the port number, the online or offline status of the ONU corresponding to each port under the OLT can be obtained. By executing the above port MAC address query command, the number of online MAC addresses of each numbered ONU connected to each port under the OLT can be obtained.

[0108] At this point, the collection of the optical network unit management status of an OLT optical network unit matching and the collection of the number of online MAC addresses matching the port information are completed.

[0109] Correspondingly, after the step of restarting the destination optical line terminal, the method further includes: step 170 and step 180.

[0110] Step 170: Acquire the working status information of the optical network unit after the cutover of the destination optical line terminal.

[0111] For the specific implementation method of obtaining the working status information of the optical network unit after the cutover of the destination optical line terminal, refer to the specific implementation method of obtaining the working status information of the optical network unit of the original optical line terminal. The difference is that when selecting the optical line terminal to be collected, it is necessary to select the manufacturer and model that matches the destination optical line terminal, which will not be repeated here.

[0112] Step 180 , obtaining analysis results of the optical network unit working states before and after the cutover based on the optical network unit working state information before and after the cutover, and the PON port cutover correspondence.

[0113] After obtaining the optical network unit operating status information of the original optical line terminal (i.e., the optical network unit operating status information before the cutover) and the optical network unit operating status information of the destination optical line terminal (i.e., the optical network unit operating status information after the cutover), the port-based (equivalent to ONU) correspondence between the optical network unit operating status information before the cutover and the optical network unit operating status information after the cutover is determined based on the PON port cutover correspondence. Then, by comparing the optical network unit operating status information before the cutover and the optical network unit operating status information after the cutover of the corresponding port, the optical network unit operating status corresponding to each optical network unit before and after the cutover is analyzed to obtain the analysis results of the optical network unit operating status before and after the cutover.

[0114] Optionally, the analysis results of the working status of the optical network unit before and after the cutover may include one or more of the following analysis results: relevant information on the online status of the optical network unit before and after the cutover, change information on the number of online MAC addresses of the optical network unit, whether the optical network unit is working normally, reasons for abnormal working of the optical network unit, etc.

[0115] In order to make the readers more clearly understand the specific implementation methods and performance of the key steps of the optical line terminal cutover method disclosed in the embodiments of the present application, further examples are given.

[0116] In step 110, the global configuration file of the optical line terminal obtained primarily includes configuration data for the following sections: pre-configuration, general configuration, VLAN configuration, GPON port configuration, service port configuration, and multicast configuration. For example, for a model of an optical line terminal from a certain manufacturer, the configuration data for each module in its global configuration file primarily includes the following.

[0117] The pre-configuration part includes: board number and model information.

[0118] The general configuration section includes: OLT login settings, DBA (Dynamically Bandwidth Assignment) template, ONU rate template and service template.

[0119] In the VLAN configuration section, users configure all VLAN information created in the OLT, such as VLAN attributes and transparent transmission ports.

[0120] The GPON port configuration part is the data configuration of the ONU under all GPON ports, including, for example, configuration data of the ONU's logical ID, rate, VLAN, etc.

[0121] The service port configuration section includes: port aggregation information and VLAN transposition.

[0122] The multicast configuration part is to enable multicast for the corresponding service port, including: the configuration information of enabling or disabling the corresponding service port.

[0123] The contents (eg, configuration items) configured in the global configuration files of optical line terminals of different manufacturers and models are similar, and are not listed one by one here.

[0124] Figure 3 The following is a diagram showing the partial contents of a global configuration file of an optical line terminal. Figure 3 As shown, the global configuration file sets various parameters required for the normal operation of the optical line terminal. In the global configuration file, the configuration data is presented in the form of script language or text and is formatted according to a preset format to facilitate parsing and translation.

[0125] In step 120, the PON port cutover correspondence is generated based on the pre-cutover port correspondence planned on-site. The PON port cutover correspondence includes the correspondence between the port information of the original optical line terminal (OLT) connected to the ONU and the port information of the destination optical line terminal (OLT) connected to the ONU after the cutover. The port information includes the management IP address, board number, slot number, and port number of the connected ONT.

[0126] For example, when the management IP address of the original optical line terminal is 106.5.1.14 and the management IP address of the destination optical line terminal is 106.5.18.138, and during on-site planning, the ONU connected to port 1 of slot 2 of board 1 of the original optical line terminal needs to be connected to port 1 of slot 1 of board 1 of the destination optical line terminal, in the obtained PON port cutover correspondence, the PON port cutover correspondence of the ONU can be represented by the following two groups of port information correspondences: ((106.5.1.14, 1, 2, 1), (106.5.18.138, 1, 1, 1)), where the first group of port information (106.5.1.14, 1, 2, 1) is the port information of the original optical line terminal connected to the ONU, and the second group of port information (106.5.18.138, 1, 1, 1) is the port information of the ONU connected to the destination optical line terminal after the cutover.

[0127] In some embodiments of the present application, the port correspondence relationship before and after the cutover can be stored in the form of a text file, such as Figure 4 As shown in . Figure 4 Part of the PON port cutover correspondence file is shown in Figure 2.

[0128] In the aforementioned step 130, when generating the PON port configuration data of the destination optical line terminal based on the PON port configuration data in the global configuration file and the PON port cutover correspondence, a pre-generated translation program can be executed. The translation program reads the PON port cutover correspondence file and the global configuration file derived above, and then translates the global configuration file based on the contents of these two files to generate the target configuration file.

[0129] In some embodiments of the present application, a translation program can be written in Python and is used to translate the global configuration file of the original optical line terminal into a configuration file suitable for the destination optical line terminal in accordance with the data format required by the manufacturer of the destination optical line terminal. During the execution of the translation program, the global configuration file is first read and parsed according to the configuration data writing specifications in the configuration file of the original optical line terminal to obtain the configuration data of each original PON port; then, based on the PON port cutover correspondence, the destination PON port corresponding to each original PON port is determined, and the configuration data of the original PON port is assigned to the corresponding destination PON port; then, according to the configuration data writing specifications of the destination optical line terminal, the PON port configuration data of the destination optical line terminal is generated based on the configuration data of the destination PON port.

[0130] The translation program extracts the configuration data for the required configuration items by matching keywords with the required content. Based on the new OLT command template, it assigns values ​​to the corresponding configuration items to generate configuration data that matches the destination optical line terminal. Specifically, it matches the required partial configuration data based on the type and number of the PON port to be cutover in the original OLT (i.e., the OLT before the cutover), extracts the configuration values ​​for the corresponding configuration items, and then assigns these values ​​to the configuration items for the corresponding PON ports in the new OLT's configuration file template, thereby generating PON port configuration data that matches the destination OLT (i.e., the new OLT).

[0131] The configuration data for OLTs from different manufacturers requires different configuration items. For example, if the new OLT is a ZTE device, the configuration data will include five configuration items: loid, mng, pon_onu, vport, and igmp. If the new OLT is a Huawei device, the configuration data will need to include two configuration items: onuadd and serviceport. Therefore, in the embodiments of the present application, multiple configuration file templates are provided for OLTs from different manufacturers. The translation program can select the corresponding configuration file template based on the OLT manufacturer and model selected by the user.

[0132] Next, in step 140, the target configuration file is generated by integrating the general configuration data (i.e., global-config) of the target optical line terminal with the PON port configuration data of the target optical line terminal in accordance with the configuration file template format required by the manufacturer of the target optical line terminal. For example, the new general configuration data and PON port configuration data are combined into a new startrun.dat file. Figure 5 According to Figure 3 The global configuration files described in Figure 4 The PON port cutover correspondence shown is part of the generated target configuration file.

[0133] The general configuration data is generated by the translation program according to the configuration template set by the cutover personnel.

[0134] When generating universal configuration data, the translation program can obtain information such as the names of universal configuration templates such as rate templates and service templates in the global configuration file of the original OLT by matching preset keywords (such as ont-lineprofine and ont-srvprofine). Then, the corresponding configuration template set by the cutover personnel for the target OLT is obtained, and the universal configuration data is generated together with the obtained template name and other information.

[0135] For example, the translation program reads the original OLT configuration file and the PON port cutover correspondence; reads the OLT management IP before cutover, the port before cutover, the OLT management IP after cutover, and the port after cutover from the PON port cutover correspondence; reads all the template numbers and template names of ont-srvprofile and ont-lineprofile from the original OLT configuration file, and adds the corresponding templates to the OLT configuration file after cutover; when writing the loid (location identifier, user registration code) part of the OLT after cutover, if the original ONU feature number is an SN number, it is converted into the corresponding hexadecimal, and the corresponding loid after cutover is written according to the port after cutover; reads the original PON port type, port number, ONU number and its corresponding rate, service template information, and writes a new pon_onu in combination with the configuration template of the OLT after cutover; reads the vlan information in the original serviceport, and writes a new vport according to whether there is vlan transposition, that is, single-layer vlan or double-layer vlan, and if there is user-vlan 45, then write the corresponding igmp, for each port, collect all user-vlans involved in the port, combine with the new OLT configuration template, write a new mng, and finally get a new configuration file.

[0136] In the aforementioned step 180, obtaining the analysis results of the working status of the optical network unit before and after the cutover based on the working status information of the optical network unit before the cutover, the working status information of the optical network unit after the cutover, and the PON port cutover correspondence includes: sub-steps 1801 to 1804.

[0137] Sub-step 1801, using the port information in the optical network unit working status information before cutover as the original port information, and according to the PON port cutover correspondence, obtaining the destination port information corresponding to the original port information from the optical network unit working status information after cutover.

[0138] As previously described, the port information includes the management IP address, board number, slot number, and port number of the connected optical line terminal. The management IP address, board number, slot number, and port number form the port information in a preset format, for example, "106.5.1.14 1 / 2 / 1." In embodiments of the present application, the destination port information corresponding to the original port information can be determined by performing keyword matching between the original port information and the port information in the PON port cutover correspondence.

[0139] Sub-step 1802: Compare the optical network unit management status matching the original port information with the optical network unit management status matching the destination port information to obtain the optical network unit management status before and after the cutover corresponding to the original port information.

[0140] After determining the destination port information corresponding to the original port information, for a set of mutually corresponding original port information and destination port information, the optical network unit management status that matches the original port information in the optical network unit working status information before cutover is matched with the optical network unit management status that matches the destination port information in the optical network unit working status information after cutover, so as to obtain the optical network unit management status before and after cutover corresponding to the original port information. The optical network unit management status before and after cutover corresponding to the original port information is used to indicate any one of the following situations: the optical network unit associated with the original port information is online before and after cutover, the optical network unit associated with the original port information is offline before cutover, and the optical network unit associated with the original port information is online before cutover and offline after cutover.

[0141] In the embodiment of the present application, the corresponding original port information and destination port information correspond to the same ONU.

[0142] In some embodiments of the present application, the optical network unit management status matching the original port information is compared with the optical network unit management status matching the destination port information to obtain the optical network unit management status before and after the cutover corresponding to the original port information, including any of the following situations.

[0143] In the first case, when the optical network unit management status matched by the original port information matches the online status, and the optical network unit management status matched by the destination port information matches the offline status, the first optical network unit management status before and after the cutover is obtained, wherein the first optical network unit management status before and after the cutover is used to indicate that the optical network unit associated with the original port information is offline after the cutover. The optical network unit management status matched by the original port information matches the online status, indicating that the ONU is online on the original OLT. The optical network unit management status matched by the destination port information matches the offline status, indicating that the ONU is offline on the destination OLT. After the OLT is cutover, the ONU changes from the online status to the offline status, which may be due to a problem in the cutover process. Therefore, it is necessary to record that the optical network unit management status of the ONU after the cutover is offline.

[0144] In the second case, when the optical network unit management status matched by the original port information and the optical network unit management status matched by the destination port information all match the online status, the second optical network unit management status before and after the cutover is obtained, wherein the second optical network unit management status before and after the cutover is used to indicate that the optical network unit associated with the original port information is online before and after the cutover. The optical network unit management status matched by the original port information matches the online status, indicating that the ONU is online on the original OLT. The optical network unit management status matched by the destination port information matches the offline status, indicating that the ONU is online on the destination OLT. After the OLT is cutover, the ONU remains online, and the cutover can be considered successful. At this time, it is necessary to record that the optical network unit management status of the ONU after the cutover is normal.

[0145] In the third case, when the optical network unit management state matched by the original port information matches the offline state, and the optical network unit management state matched by the destination port information matches the online state, the third optical network unit management state before and after the cutover is obtained, wherein the third optical network unit management state before and after the cutover is used to indicate that the optical network unit associated with the original port information is offline before the cutover. The optical network unit management state matched by the original port information matches the offline state, indicating that the ONU is offline on the original OLT. The optical network unit management state matched by the destination port information matches the online state, indicating that the ONU is online on the destination OLT. After the OLT is cutover, the ONU is converted from the offline state to the online state. The possible reason is that the ONU was not online before the cutover (such as the ONU is not in use or the ONU is powered off). At this time, it is necessary to record that the optical network unit management state of the ONU before the cutover is offline.

[0146] In sub-step 1803, when the optical network unit management status before and after the cutover indicates that the optical network unit associated with the original port information is online before and after the cutover, the number of online MAC addresses matching the original port information is compared with the number of online MAC addresses matching the destination port information to obtain the online MAC address information before and after the cutover corresponding to the original port information.

[0147] Only when the ONU is in the online state can the number of online MAC addresses of the ONU be collected. Therefore, only when the ONU's optical network unit management state after cutover is normal in the above steps, the number of online MAC addresses can be further judged.

[0148] In some embodiments of the present application, the step of comparing the number of MAC addresses online that matches the original port information with the number of MAC addresses online that matches the destination port information to obtain the MAC address online information before and after the cutover corresponding to the original port information includes the following two cases.

[0149] In the first case, when the number of MAC addresses online that match the original port information is equal to zero, first MAC address online information before and after the cutover is obtained, wherein the first MAC address online information before and after the cutover is used to indicate that the optical network unit associated with the original port information has no MAC address online before the cutover.

[0150] If the number of online MAC addresses matching the original port information is zero, this indicates that no ONU on this port under the OLT device has a MAC address online before the cutover. Therefore, no troubleshooting is required when analyzing the working status of the PON port before and after the cutover.

[0151] In the second case, when the number of MAC addresses online that match the original port information is greater than zero, the second MAC address online information before and after the cutover is obtained according to the relationship between the number of MAC addresses online that match the original port information and the number of MAC addresses online that match the destination port information, wherein the second MAC address online information before and after the cutover is used to indicate that the number of MAC addresses online of the optical network unit associated with the original port information decreases or is normal after the cutover.

[0152] When the number of online MAC addresses matching the original port information is greater than zero, it is necessary to further determine the change in the number of online MAC addresses matching the destination port information after the cutover relative to the number of online MAC addresses matching the original port information. If the number of online MAC addresses matching the destination port information is greater than or equal to the number of online MAC addresses matching the original port information, it can be assumed that the MAC addresses that were online before the cutover are still online, that is, the cutover is successful. In this case, the information that the number of online MAC addresses after the cutover is normal is obtained. If the number of online MAC addresses matching the destination port information is less than the number of online MAC addresses matching the original port information, it can be assumed that the MAC addresses that were online before the cutover are not online after the cutover. It is necessary to further check whether a port cutover error occurred during the cutover process. In this case, the information that the number of online MAC addresses after the cutover has decreased is obtained.

[0153] Sub-step 1804 , obtaining an analysis result of the optical network unit working status before and after the cutover corresponding to the original port information according to the optical network unit management status before and after the cutover and the MAC address online information before and after the cutover.

[0154] After obtaining the optical network unit management status and MAC address online information before and after the cutover corresponding to each ONU (i.e., each port information), the optical network unit management status and MAC address online information before and after the cutover are integrated based on the port information to obtain the optical network unit working status analysis results before and after the cutover corresponding to each ONU (i.e., port information). Figure 6 Taking the optical network unit working status analysis results before and after the cutover shown in as an example, the optical network unit working status analysis results before and after the cutover corresponding to a certain port information can be expressed as: "106.5.1.14 1 / 2 / 1:2 106.5.18.138 1 / 2 / 1:2 ONU normal MAC normal", where "106.5.1.14 1 / 2 / 1:2" is a port number of the original OLT before the cutover, and "106.5.18.138 1 / 2 / 1:2" is a port number of the destination OLT after the cutover.

[0155] The ONU working status analysis results before and after the cutover show three comparison results for ONU online status before and after the cutover: ONU normal, ONU offline before the cutover, and ONU offline. The MAC address comparison results also show three results: MAC normal, MAC reduction, and MAC before the cutover. "ONU normal" means the ONU is online before and after the cutover, "ONU offline" means the ONU is online before the cutover but offline after the cutover, and "MAC normal" means the MAC count remains the same after the cutover. Only when the ONU is normal will the number of online MAC addresses be checked.

[0156] According to the analysis results of the working status of the optical network unit before and after the cutover, it can be seen that: when the ONU and MAC are normal, it means that the user service is normal; when the ONU is normal and the MAC is reduced, it means that there may be a fault after the cutover, and further identification of the fault point is required to check whether there is any configuration missing; when the ONU is normal and there is no MAC before the cutover, it means that no MAC is online on the user side before the cutover and no action is required; when the ONU is not online before the cutover, it means that the ONU is not in use or the ONU is powered off before the cutover and no action is required; when the ONU is not online, it means that there may be a fault during the cutover process and further inspection of the on-site pigtail and line quality is required to determine the fault point (for example, if the entire PON port shows "ONU not online", check whether the PON port is open, the quality of the optical module, etc. If all of the above are fine, it can be located as a power outage during the user cutover process).

[0157] It can be seen that the analysis results of the optical network unit working status before and after the cutover provide a fast and effective means to verify whether the cutover work is carried out accurately, thereby ensuring the reliability of the OLT cutover.

[0158] In some embodiments of the present application, before importing the target configuration file into the destination optical line terminal, the number of PON ports that need to be cutover can be determined first. When the current cutover is a single PON port cutover, or a few PON ports cutover, rather than a cutover of all PON ports of the entire OLT, the configuration data in the target configuration file can be sent to the destination OLT by manually executing telnet to shorten the cutover time.

[0159] The optical line terminal cutover method disclosed in an embodiment of the present application comprises the following steps: obtaining a global configuration file of an original optical line terminal; obtaining a PON port cutover correspondence when the original optical line terminal is cutover to a destination optical line terminal; generating PON port configuration data of the destination optical line terminal based on the PON port configuration data in the global configuration file and the PON port cutover correspondence; concatenating the PON port configuration data of the destination optical line terminal with the general configuration data of the destination optical line terminal to obtain a target configuration file; importing the target configuration file into the destination optical line terminal; and restarting the destination optical line terminal so that the target configuration file takes effect on the restarted destination optical line terminal, thereby improving OLT cutover efficiency and shortening cutover time.

[0160] The optical line terminal cutover method disclosed in the embodiment of the present application generates a configuration file for the destination OLT by translating the global configuration file of the original OLT based on the cutover correspondence of the PON ports, and imports the generated configuration file into the destination OLT. This eliminates the need to manually send configuration data using a single instruction for manual cutover. This not only improves the cutover efficiency of the entire OLT and shortens the cutover time, but also reduces the error rate and improves the cutover accuracy.

[0161] Furthermore, the optical line terminal cutover method disclosed in the embodiment of the present application automatically collects and compares the ONU status and MAC address online information before and after the cutover, and outputs the comparison results to guide the cutover personnel to perform analysis and troubleshooting, facilitate real-time processing of cutover faults, help ensure that the user status before and after the OLT cutover is basically consistent, and ensure the accuracy of the cutover.

[0171] After restarting the destination optical line terminal, Figure 8 As shown, the device also includes:

[0172] The post-cutover optical network unit working status information collection module 770 is used to obtain the post-cutover optical network unit working status information of the destination optical line terminal;

[0173] The optical network unit working status analysis result acquisition module 780 before and after cutover is used to obtain the optical network unit working status analysis results before and after cutover based on the optical network unit working status information before cutover, the optical network unit working status information after cutover, and the PON port cutover correspondence.

[0174] Optionally, the module 780 for obtaining the analysis results of the optical network unit working status before and after the cutover is further configured to:

[0178] According to the management status of the optical network unit before and after the cutover and the online MAC address information before and after the cutover, the analysis result of the working status of the optical network unit before and after the cutover corresponding to the original port information is obtained.

[0185] When the number of online MAC addresses matched by the original port information is greater than zero, second online MAC address information before and after the cutover is obtained based on a relationship between the number of online MAC addresses matched by the original port information and the number of online MAC addresses matched by the destination port information, wherein the second online MAC address information before and after the cutover is used to indicate that the number of online MAC addresses of the optical network unit associated with the original port information decreases or is normal after the cutover.
