[0035] This invention proposes a network device control method, apparatus, device, system, and storage medium. When a communication failure occurs between the optical line terminal equipment (OLT) and the virtual node of the OLT in the server, the OLT performs a first control operation on the user network terminal based on first data information backed up from the virtual node, and stores second data information generated by the first control operation. Furthermore, when communication between the OLT and the virtual node is restored, the second data information is sent to the virtual node, enabling the virtual node to perform a second control operation on the user network terminal based on this second data information. This is because data backup is performed between the virtual node and the physical OLT device. Therefore, in the event of a communication failure, the physical OLT device can take over the control tasks of the OLT virtual node based on the backup data, and after communication is restored, back up the control data generated to the OLT virtual node. This solves the problem that the inability to communicate normally between the physical OLT device and the OLT virtual node causes the user network terminal to malfunction, thus affecting user experience. It achieves the effect of transferring the control function of the OLT virtual node over the user network terminal to the physical OLT device when a failure occurs. This invention is a fault protection mechanism proposed for communication failures between the physical OLT device and the OLT virtual node, which can effectively ensure the normal operation of the user network terminal, prevent impact on user experience, and improve the user experience during system failures.

[0051] Terminology Explanation:

[0052] OLT: Optical Line Terminal, a terminal device used to connect to an optical fiber trunk. It provides a network-side interface for an optical access network and is connected to one or more optical distribution networks.

[0053] ONT: Optical Network Terminal, is a product in xPON (Passive Optical Network) network access solutions, and is an optical network terminal used at the user end.

[0054] ONU: Optical Network Unit, is a terminal device for fiber optic access, used in conjunction with OLT equipment;

[0055] OMCI: ONU Management and Control Interface, is a protocol defined in the GPON standard for information exchange between the OLT and ONT, used for OLT management of the ONT in GPON (Gigabit-Capable Passive Optical Networks) networks.

[0056] NFV: Network Functions Virtualization, a concept for network architecture that uses virtualization technology to divide the functions of network nodes into several functional blocks, which are implemented in software and are no longer limited to hardware architecture.

[0057] EMS: Network Element Management System, is a system that manages one or more NEs (Net Element) of a specific type.

[0058] Analysis of existing technologies reveals that transferring the management and control functions of user network terminals from physical OLT devices to OLT virtual nodes, with centralized management and control of user network terminals at the OLT virtual nodes, offers several advantages. Firstly, it allows user network terminals from different manufacturers to be deployed uniformly under a single physical OLT device, reducing network deployment and testing costs and improving network flexibility. Secondly, it simplifies the functions of physical OLT devices, reducing configuration complexity during installation, commissioning, and maintenance, thereby lowering labor costs and maintenance requirements. Therefore, OLT device virtualization technology has gradually separated the control plane and forwarding devices of broadband access equipment, achieving an open, unified, and centralized control plane, as well as cloud deployment, enhancing the flexibility and convenience of existing wired access network endpoints.

[0059] Currently, in practical deployments of OLT device virtualization technology, OLT virtual nodes are typically deployed in central or provincial data centers due to their centralized management, while physical OLT devices are usually deployed at aggregation or access nodes. Therefore, when the fiber optic cable between the physical OLT device and the OLT virtual node is interrupted, or when the OLT virtual node fails, they cannot communicate normally, hindering the management and control of user network terminals and significantly impacting customer experience.

[0060] In view of the technical problem in the prior art where user network terminals cannot function properly and affect user experience when physical OLT devices and OLT virtual nodes cannot communicate normally, this invention provides a network device control method, the overall idea of ​​which is as follows:

[0061] When applied to an optical line terminal equipment (OLT), the method includes: when a communication failure occurs between the OLT and an OLT virtual node in a server, performing a first control operation on a user network terminal based on first data information in the OLT, and storing second data information generated by the first control operation; wherein the first data information is obtained by backup from the OLT virtual node; when communication between the OLT and the OLT virtual node returns to normal, sending the second data information to the OLT virtual node, so that the OLT virtual node performs a second control operation on the user network terminal based on the second data information.

[0062] When applied to a server including an optical line terminal virtual node, the method includes: backing up first data information in the optical line terminal virtual node to an optical line terminal device, so that when there is a communication failure between the optical line terminal device and the optical line terminal virtual node, the optical line terminal device performs a first control operation on a user network terminal based on the first data information and stores second data information generated by the first control operation; when communication between the optical line terminal device and the optical line terminal virtual node returns to normal, the method receives the second data information sent by the optical line terminal device and performs a second control operation on the user network terminal based on the second data information.

[0063] Through the above technical solution, when a communication failure occurs between the optical line terminal equipment (OLT) and the virtual OLT node in the server, a first control operation is performed on the user network terminal based on the first data information backed up by the OLT from the virtual OLT node, and the second data information generated by the first control operation is stored. When communication between the OLT and the virtual OLT node returns to normal, the second data information is sent to the virtual OLT node, enabling the virtual OLT node to perform a second control operation on the user network terminal based on the second data information. Because data backup is performed between the OLT virtual node and the physical OLT device, in the event of a communication failure, the physical OLT can perform a second control operation on the user network terminal. The physical OLT device can take over the control tasks of the OLT virtual node based on backup data, and back up the control data generated to the OLT virtual node after communication is restored. This solves the problem of user network terminals malfunctioning due to communication failure between the physical OLT device and the OLT virtual node, thus affecting user experience. It achieves the effect of transferring the control function of the OLT virtual node over the user network terminal to the physical OLT device when a fault occurs. This invention is a fault protection mechanism proposed for communication failures between the physical OLT device and the OLT virtual node, which can effectively ensure the normal operation of user network terminals, prevent impact on user experience, and improve user experience during system failures.

[0064] Example 1

[0065] Reference Figure 1 This is a flowchart illustrating the first embodiment of the network device control method of the present invention. This embodiment provides a network device control method applicable to optical line terminal equipment (OLTs), where the OLT is a physical OLT device located within an OLT virtualization system.

[0066] Traditional OLT equipment is part of the PON access network, deployed in the central office equipment room, serving as the service centralization point of the PON access network. It can connect to user network terminals via optical splitters. User network terminals can be either ONTs or ONUs, such as... Figure 2The diagram shown illustrates the connection between a traditional OLT device and an ONT.

[0067] like Figure 3 The diagram shows a traditional OLT (Optical Line Terminal) network architecture. In a traditional PON (Public-Network-Transfer) network, the OLT manages and controls the ONTs (Online Telephone Units) through the OMCI (Optical Configuration Interface). The OMCI interface is a configuration transmission channel defined in the GPON standard, which transmits OMCI messages by establishing a dedicated ATM PVC or GEM PORT between the OLT and the ONT. The ONT establishes an OMCI channel when registering with the OLT. OMCI is a master-slave management protocol; the OLT is the master, and the ONT is the slave. The OLT manages and controls multiple ONTs through the OMCI channel.

[0068] like Figure 4 The diagram shown illustrates the networking architecture of the OLT virtualization system in this embodiment. In the OLT virtualization system, the physical OLT device is connected to multiple user network terminals and to a server via optical fiber. This OLT virtualization system is based on the NFV (Network Functions Virtualization) architecture, separating the control plane and forwarding plane of the traditional OLT device. It centralizes the management and control functions for user network terminals, forming OLT virtual nodes. The physical OLT device serves as the OMCI information transmission channel, allowing the OLT virtual nodes to perform unified management and control of user network terminals through the physical OLT device. The user network terminals include ONTs and / or ONUs. The physical OLT device is deployed at aggregation nodes or access nodes, and the server is deployed in a data center at a city center or provincial center.

[0069] Specifically, the server may consist only of OLT virtual nodes. In actual deployment, the OLT virtual nodes and the EMS system are deployed separately, and the OLT virtual nodes are connected to the EMS system, such as... Figure 4 As shown; the server may also include both OLT virtual nodes and EMS systems. In actual deployment, the OLT virtual nodes can be incorporated into the EMS system for unified deployment.

[0070] The following is combined Figure 1 Flowchart and Figure 4 The diagram illustrates the networking architecture of an OLT virtualization system. A detailed description of the network device control method provided in this embodiment is given, which may include the following steps:

[0071] Step S120: When there is a communication failure between the optical line terminal equipment and the optical line terminal virtual node in the server, a first control operation is performed on the user network terminal according to the first data information in the optical line terminal equipment, and the second data information generated by the first control operation is stored; wherein, the first data information is obtained by backup from the optical line terminal virtual node.

[0072] Specifically, communication failures include fiber optic cable interruptions between the optical line terminal equipment (OLT) and the server, or failures of the OLT virtual node within the server. Before a communication failure occurs between the physical OLT device and the OLT virtual node in the server, the OLT virtual node uses the physical OLT device as a channel, i.e., a transparent OMCI interface, to perform virtualization management and control of the user network terminal, and saves the corresponding initial data information, such as user information, user registration information, service information, ONT / ONU configuration information, and other interactive information. Simultaneously, it backs up and transmits this initial data information to the physical OLT device for local storage, achieving real-time synchronization of the initial data information. The virtualization management and control can include operations such as configuration management, fault management, performance management, security management, user registration, ONU activation, MIB (Management Information Base) auditing and synchronization, GEM (Graph Embedding) connection mode negotiation, DBA (Dynamically Bandwidth Assignment), PON (Passive Optical Network) layer channel configuration, time synchronization, and performance data reporting.

[0073] In practical implementation, when the physical OLT device cannot receive the first data information transmitted by the OLT virtual node, it indicates a communication failure between the physical OLT device and the OLT virtual node. At this time, the physical OLT device uses the first data information backed up from the OLT virtual node to perform a first control operation on the user network terminal and locally stores the second data information generated by the first control operation, such as user information, user registration information, service information, and ONT / ONU configuration information. In other words, the management and control of the user network terminal by the OLT virtual node is transferred to the physical OLT device, meaning the physical OLT device performs physical management and control of the user network terminal. The first control operation may include device configuration and operation operations on the user network terminal; it may also include receiving and storing operation operations on the running data and alarm information sent by the user network terminal, to realize daily functions such as ONT discovery, ONT re-connection, and ONT power-off recovery, preventing unconnected ONTs from failing to complete normal online work and affecting the normal use of existing services and users.

[0074] In this embodiment, after a communication failure occurs between the physical OLT device and the OLT virtual node, the OLT virtual node will send relevant alarm information to the EMS system to remind maintenance personnel to handle the fault in a timely manner.

[0075] Step S140: When the communication between the optical line terminal equipment and the optical line terminal virtual node is restored to normal, the second data information is sent to the optical line terminal virtual node so that the optical line terminal virtual node can perform a second control operation on the user network terminal according to the second data information.

[0076] Specifically, during step S120, if maintenance personnel discover a fault, and the physical OLT device performs the first control operation on the user network terminal without affecting user access, they should promptly troubleshoot the fault. Once the fault is resolved and communication between the physical OLT device and the OLT virtual node is restored to normal, the physical OLT device will send the second data information generated by the first control operation stored locally to the OLT virtual node. This allows the OLT virtual node to perform the second control operation on the user network terminal based on the second data information. In other words, the management and control of the user network terminal by the physical OLT device is transferred back to the OLT virtual node, restoring normal operation.

[0077] In specific implementation, the second control operation may include device configuration operation and operation operation of the user network terminal; it may also include receiving operation and storage operation of operation data and alarm information sent by the user network terminal, so as to realize daily functions such as ONT discovery, ONT re-online, and ONT power failure recovery.

[0078] In this embodiment, the operation logs and alarms generated by the physical OLT device during the first control operation on the user network terminal are uploaded to the OLT virtual node to ensure that data is not lost during the fault. When the OLT virtualization system recovers from the fault, the EMS system transmits the corresponding fault recovery information and the EMS system configuration information during the fault to the OLT virtual node, ensuring the integrity of network operation and maintenance information.

[0079] In one embodiment, prior to step S120, the method may further include:

[0080] Step S110: Back up data from the optical line terminal virtual node to obtain the first data information; wherein, the first data information includes data generated by the optical line terminal virtual node when performing a third control operation on the user network terminal before the communication failure between the optical line terminal equipment and the optical line terminal virtual node.

[0081] Specifically, before the physical OLT device and the OLT virtual node fail, the OLT virtual node performs a third control operation on the user network terminal and locally stores the first data information generated by the third control operation, such as user information, user registration information, service information, ONT / ONU configuration information, and other interactive information.

[0082] In a specific implementation, the third control operation may include device configuration and operation of the user network terminal; it may also include receiving and storing operation data and alarm information sent by the user network terminal to realize routine functions such as ONT discovery, ONT re-connection, and ONT power failure recovery. The specific settings can be configured according to actual needs.

[0083] In this embodiment, under normal conditions, i.e. when the OLT virtualization system is not faulty, the user network terminal is virtualized and controlled through the OLT virtual node, and the corresponding first data information is synchronously backed up to the physical OLT device. This ensures that in the event of a fault, the physical OLT device can promptly perform physical management and control of the user network terminal based on the first data information, preventing the fault from affecting the normal operation of the user network terminal.

[0084] In another embodiment, prior to step S110, the method may further include:

[0085] Step S101: Receive the user registration application sent by the network terminal of the user to be registered.

[0086] Step S102: Send the user registration application to the optical line terminal virtual node, so that the optical line terminal virtual node can complete the registration of the user network terminal to be registered based on the user configuration information of the user network terminal device to be registered and the user registration application, and obtain the user network terminal device, wherein the optical line terminal virtual node stores the user configuration information of the user network terminal device to be registered.

[0087] Specifically, when a new user network terminal (i.e., a user network terminal to be registered) is activated in the OLT virtualization system, staff will first configure the user information and corresponding business information to the OLT virtual node via the EMS system. This means storing the user configuration information of the user network terminal to be registered and synchronously backing it up to the physical OLT device. When the physical OLT device receives a user registration application from the user network terminal to be registered (i.e., upon initial online access), the physical OLT device forwards the user registration application and corresponding interaction information to the OLT virtual node. The physical OLT device does not perform any processing; the OLT virtual node interacts with the user network terminal to be registered based on the stored user configuration information to complete the registration. Thus, the user network terminal to be registered becomes a user network terminal in the OLT virtualization system, and the newly activated user becomes an existing user. Furthermore, if the configuration of the user network terminal changes subsequently, the EMS system directly modifies the user network terminal's configuration information stored on the OLT virtual node, completing the configuration adjustment and synchronizing the latest user configuration information to the physical OLT device. This ensures timely information updates in case of failure.

[0088] In practice, if a user's network terminal malfunctions during normal operation, the OLT virtualization node can transmit relevant alarm information to the EMS system to remind the user to perform timely maintenance.

[0089] In this embodiment, the user network terminal of a newly activated user is registered. After registration, the newly activated user becomes an existing user, and the user network terminal to be registered becomes the user network terminal of that existing user. Thus, in the event of a system failure, the method of this embodiment can ensure the normal operation of the user network terminals of all existing users.

[0090] The network device control method provided in this embodiment performs a first control operation on the user network terminal based on first data information backed up by the optical line terminal device from the optical line terminal virtual node in the server when there is a communication failure between the optical line terminal device and the optical line terminal virtual node in the server. It also stores second data information generated by the first control operation. Furthermore, when communication between the optical line terminal device and the optical line terminal virtual node is restored, the second data information is sent to the optical line terminal virtual node, enabling the optical line terminal virtual node to perform a second control operation on the user network terminal based on the second data information. Because data backup is performed between the OLT virtual node and the physical OLT device, during communication... In the event of a failure, the physical OLT device can take over the control tasks of the OLT virtual node based on backup data. After communication is restored, it backs up the control data generated to the OLT virtual node, thus solving the problem of user network terminals malfunctioning due to the inability to communicate normally between the physical OLT device and the OLT virtual node, thereby affecting user experience. This invention achieves the effect of transferring the control function of the OLT virtual node over the user network terminal to the physical OLT device when a failure occurs. This invention is a fault protection mechanism proposed for communication failures between the physical OLT device and the OLT virtual node, which can effectively ensure the normal operation of user network terminals, prevent impact on user experience, and improve the user experience during system failures.

[0091] Example 2

[0092] Based on the same inventive concept, referring to Figure 5 This is a flowchart illustrating a second embodiment of the network device control method of the present invention. This embodiment provides a network device control method applicable to a server, wherein the server includes an optical line terminal virtual node.

[0093] The server may consist only of an optical line terminal (OLT) virtual node. The server connects to the terminal where the EMS system resides; that is, the OLT virtual node and the EMS system are deployed separately, and the OLT virtual node communicates with the EMS system. Figure 4 As shown; the server can also include both an optical line terminal (OLT) virtual node and an EMS system, that is, the OLT virtual node and the EMS system are deployed on the same server and communicate internally. Specific configurations can be made according to actual needs.

[0094] The following is combined Figure 5 The network device control method provided in this embodiment will be described in detail. The method may include the following steps:

[0095] Step S220: Back up the first data information in the optical line terminal virtual node to the optical line terminal device, so that when there is a communication failure between the optical line terminal device and the optical line terminal virtual node, the optical line terminal device can perform a first control operation on the user network terminal according to the first data information, and store the second data information generated by the first control operation.

[0096] Specifically, before the physical OLT device and the OLT virtual node fail, when the OLT virtual node performs virtualized management and control of the user network terminal, the first data information generated will be synchronously backed up to the optical line terminal device. In the event of a failure such as the optical cable between the optical line terminal device and the server being interrupted, or the optical line terminal virtual node in the server failing, the physical OLT device will use this first data information to perform physical management and control of the user network terminal, i.e., the first control operation, and store the second data information generated corresponding to the first control operation.

[0097] In practice, when physical OLT devices manage and control user network terminals, staff can troubleshoot the causes of faults without affecting user use, thus improving the user experience.

[0098] Step S240: When the communication between the optical line terminal device and the optical line terminal virtual node is restored to normal, the second data information sent by the optical line terminal device is received, and the second control operation is performed on the user network terminal according to the second data information.

[0099] Specifically, after the communication between the physical OLT device and the OLT virtual node is restored to normal, the OLT virtual node obtains the fault recovery information from the EMS system and the second data information from the physical OLT device. Then, it uses the second data information to perform the second control operation on the user network terminal. At this time, the physical OLT device is restored to the OMCI information pass-through channel, and the OLT virtual node continues to manage and control the user network terminal.

[0100] In one embodiment, prior to step S220, the method may further include:

[0101] Step S210: Before a communication failure occurs between the optical line terminal equipment and the optical line terminal virtual node, a third control operation is performed on the user network terminal, and the first data information generated by the third control operation is stored.

[0102] Specifically, under normal conditions, the OLT virtual node uses the physical OLT device as a channel, i.e., transparently transmitting the OMCI interface, to perform virtualized management and control of the user network terminal, and saves the corresponding first data information, such as user information, user registration information, service information, ONT / ONU configuration information, and other interactive information. This first data information is also synchronously backed up to the physical OLT device so that, in the event of a fault, the physical OLT device can call upon this first data information to perform physical management and control of the user network terminal.

[0103] In the specific implementation process, the OLT virtualization system goes through three stages: normal state, fault state, and fault recovery state. The corresponding operations are: the OLT virtual node performs the third control operation on the user network terminal, the physical OLT device performs the first control operation on the user network terminal, and then the OLT virtual node performs the second control operation on the user network terminal.

[0104] Saving data at different stages ensures the integrity of the entire OLT virtual system data, prevents data loss, and avoids affecting the normal operation of user network terminals.

[0105] In another embodiment, the optical line terminal virtual node stores user configuration information of the network terminal device of the user to be registered. Before step S210, the method may further include:

[0106] Step S201: Receive the user registration application for the network terminal to be registered sent by the optical line terminal equipment;

[0107] Step S202: Register the network terminal of the user to be registered based on the user configuration information and the user registration application to obtain the user network terminal device.

[0108] Specifically, when adding a new user terminal to be registered, the user information and corresponding business information are first configured by staff in the EMS system to the OLT virtual node. This means the user configuration information of the network terminal to be registered is stored and synchronously backed up to the physical OLT device. Then, the physical OLT device forwards the user registration application (initial online application) sent by the network terminal to be registered to the OLT virtual node. Upon receiving the initial online application, the OLT virtual node interacts with the network terminal to be registered based on the stored user configuration information and the initial online application to complete the registration. The new user's network terminal then becomes the existing user's network terminal. Throughout this process, the physical OLT device acts as a transparent OMCI interface channel.

[0109] The network device control method provided in this embodiment backs up the first data information in the optical line terminal virtual node of the server to the optical line terminal device. This allows the optical line terminal device to perform a first control operation on the user network terminal based on the first data information when a communication failure occurs between the optical line terminal device and the optical line terminal virtual node, and to store the corresponding second data information. Furthermore, when communication between the optical line terminal device and the optical line terminal virtual node returns to normal, the method receives the second data information sent by the optical line terminal device and performs a second control operation on the user network terminal based on the second data information. This ensures the normal operation of the user network terminal even when communication between the optical line terminal device and the optical line terminal virtual node fails, preventing disruption to user use. It also ensures the integrity of the OLT virtualization system data, preventing data asynchrony before and after the failure from causing abnormal operation of the user network terminal.
