Therefore, the OLT equipment virtualization technology gradually realizes the separation of the control plane and the forwarding equipment of the broadband access equipment, realizes the open, unified and centralized control plane and the cloud deployment, and enhances the flexibility and convenience of the networking of the tail end of the existing wired access network.
In an actual deployment scheme of an OLT device virtualization technology at present, because an OLT virtual node adopts a centralized management and control manner, the OLT virtual node is often deployed in machine rooms of a city center and a provincial center, and an entity OLT device is often deployed in a sink node and an access node. Therefore, when the optical cable between the entity OLT device and the OLT virtual node is interrupted or the OLT virtual node fails, the entity OLT device and the OLT virtual node cannot normally communicate, so that management and control of the user network terminal cannot be completed, and the customer experience is greatly influenced.
In view of the technical problem that a user network terminal cannot normally work and the use of a user is affected when the entity OLT equipment and the OLT virtual node cannot normally communicate in the prior art, the invention provides a network equipment control method, which has the following general idea:
when the method is applied to the optical line terminal equipment, the method comprises the following steps: when the optical line terminal equipment and an optical line terminal virtual node in a server have communication faults, first control operation is carried out on a user network terminal according to first data information in the optical line terminal equipment, and second data information generated by the first control operation is stored; the first data information is obtained from the optical line terminal virtual node in a backup mode; and when the communication between the optical line terminal equipment and the optical line terminal virtual node is recovered to be normal, sending the second data information to the optical line terminal virtual node so that the optical line terminal virtual node performs second control operation on the user network terminal according to the second data information.

Fig. 1 is a flowchart illustrating a network device control method according to a first embodiment of the present invention. The embodiment provides a network device control method applicable to an optical line termination device, where the optical line termination device is an entity OLT device located in an OLT virtualization system.
The traditional OLT equipment is a part of a PON access network, is deployed in a local side machine room, serves as a service concentration point of the PON access network, and can be connected with a user network terminal through an optical splitter. The user network terminal may be an ONT or an ONU, as shown in fig. 2, which is a schematic diagram illustrating a connection between a conventional OLT device and an ONT.
Fig. 3 is a schematic diagram of a networking architecture of a conventional OLT device, in which the OLT device manages and controls ONTs through OMCI interfaces. The OMCI interface is a configuration transmission channel defined in GPON standard, and transmits OMCI message by establishing a proprietary ATM PVC or GEM PORT between the OLT equipment and the ONT. The ONT establishes an OMCI channel when registering with the OLT device, the OMCI is a master-slave management protocol, the OLT device is a master device, the ONT is a slave device, and the OLT device manages and controls the ONTs through the OMCI channel.
As shown in fig. 4, which is a schematic diagram of a networking architecture of an OLT Virtualization system according to this embodiment, in the OLT Virtualization system, an entity OLT device is connected to a plurality of user Network terminals and is connected to a server through an optical cable, the OLT Virtualization system is a system networking architecture based on an NFV (Network function Virtualization) system, a control plane and a forwarding plane of a conventional OLT device are separated, partial management and control Functions of the user Network terminals are centrally deployed to form an OLT virtual node, the entity OLT device serves as an OMCI information transparent transmission channel, and the OLT virtual node completes unified management and control of the user Network terminals through the entity OLT device. The user network terminal comprises ONTs and/or ONUs, the entity OLT equipment is deployed in a convergence node or an access node, and the server is deployed in a machine room of a city center or a provincial center.
Specifically, the server may include only an OLT virtual node, and during actual deployment, the OLT virtual node and the EMS system are deployed separately, and the OLT virtual node is connected to the EMS system, as shown in fig. 4; the server can also comprise an OLT virtual node and an EMS system, and the OLT virtual node can be incorporated into the EMS system for uniform deployment during actual deployment.
The following describes in detail the network device control method provided in this embodiment with reference to the flowchart of fig. 1 and the schematic diagram of the networking architecture of the OLT virtualization system of fig. 4, where the method may include the following steps:
step S120: when the optical line terminal equipment and an optical line terminal virtual node in a server have communication faults, first control operation is carried out on a user network terminal according to first data information in the optical line terminal equipment, and second data information generated by the first control operation is stored; and the first data information is obtained from the optical line terminal virtual node in a backup mode.
Specifically, the communication failure condition includes a condition that an optical cable between the optical line terminal device and the server is interrupted, or an optical line terminal virtual node in the server fails. Before the entity OLT equipment and the OLT virtual node in the server have communication faults, the OLT virtual node takes the entity OLT equipment as a channel, namely, a transparent transmission OMCI interface, performs virtualization management and control on a user network terminal, and stores correspondingly generated first data information, such as user information, user registration information, service information, ONT/ONU configuration information and other interaction information. Meanwhile, the first data information backup is transmitted to the entity OLT equipment for local storage, and real-time synchronization of the first data information is realized. The virtualization Management and control may include configuration Management, fault Management, performance Management, security Management, user registration, ONU activation, MIB (Management Information Base) audit and synchronization, GEM (Graph embedding, sensor Network) connection mode negotiation, DBA (dynamic Bandwidth allocation), PON (Passive Optical Network ) layer channel configuration, time synchronization, and performance data reporting.
In a specific implementation process, when the entity OLT device cannot receive the first data information transmitted by the OLT virtual node, it is indicated that there is a communication fault between the entity OLT device and the OLT virtual node, and at this time, the entity OLT device performs a first control operation on the user network terminal by using the first data information obtained by the entity OLT device from the OLT virtual node backup, and locally stores second data information generated by the first control operation, such as interaction information such as user information, user registration information, service information, ONT/ONU configuration information, and the like. That is, the management and control of the OLT virtual node to the user network terminal are transferred to the materialized OLT device, that is, the materialized OLT device performs the materialized management and control to the user network terminal. Wherein, the first control operation may include a device configuration operation and an operation on the user network terminal; the method can also comprise receiving operation and storing operation of operation data and alarm information sent by the user network terminal so as to realize daily functions of ONT discovery, ONT secondary online, ONT power failure recovery and the like, and avoid the situation that the non-accessed ONT can not complete normal online work and influence the normal use of the existing service and users.
In this embodiment, after a communication failure occurs between the entity OLT device and the OLT virtual node, the OLT virtual node may send related warning information to the EMS system to remind a maintainer to handle the failure in time.
Step S140: and when the communication between the optical line terminal equipment and the optical line terminal virtual node returns to normal, sending the second data information to the optical line terminal virtual node so that the optical line terminal virtual node performs second control operation on the user network terminal according to the second data information.
Specifically, when step S120 is executed, the maintainer finds a fault condition, performs fault elimination in time on the premise that the use of the user is not affected when the entity OLT device performs a first control operation on the user network terminal, and after the fault elimination, that is, when the communication between the entity OLT device and the OLT virtual node is recovered to normal, the entity OLT device sends second data information, which is generated corresponding to the locally stored first control operation, to the OLT virtual node, so that the OLT virtual node performs a second control operation on the user network terminal according to the second data information, that is, the management and control of the user network terminal by the entity OLT device are switched back to the OLT virtual node to recover the normal condition.
In a specific implementation process, the second control operation may include a device configuration operation and an operation on the user network terminal; the method can also comprise receiving operation and storing operation of the operation data and the alarm information sent by the user network terminal so as to realize daily functions of ONT discovery, ONT secondary online, ONT power failure recovery and the like.
In this embodiment, information such as an operation log and an alarm generated by the entity OLT device performing the first control operation on the user network terminal during the fault period is uploaded to the OLT virtual node, so that data during the fault period is not lost. When the OLT virtualization system of this embodiment recovers from a failure, the EMS system transmits corresponding failure recovery information and EMS system configuration information during the failure to the OLT virtual node, thereby ensuring the integrity of network operation and maintenance information.
In one embodiment, before the step S120, the method may further include:
step S110: performing data backup from the optical line terminal virtual node to obtain the first data information; the first data information includes data generated by the optical line terminal virtual node performing a third control operation on the user network terminal before a communication fault exists between the optical line terminal device and the optical line terminal virtual node.
Specifically, before the entity 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 first data information generated by the third control operation, such as user information, user registration information, service information, ONT/ONU configuration information, and other interaction information.
In a specific embodiment, the third control operation may include a device configuration operation, a running operation of the user network terminal; the method can also comprise receiving operation and storing operation of the operation data and the alarm information sent by the user network terminal so as to realize daily functions of ONT discovery, ONT secondary online, ONT power failure recovery and the like. The setting can be specifically carried out according to actual requirements.
In this embodiment, in a normal state, that is, when the OLT virtualization system has no fault, the OLT virtual node performs virtualization management and control on the user network terminal, and synchronously backs up the correspondingly generated first data information to the entity OLT device, so as to ensure that the entity OLT device can perform materialization management and control on the user network terminal according to the first data information in time when a fault occurs, thereby preventing the fault from affecting the normal operation of the user network terminal.
In another embodiment, before the step S110, the method may further include:
step S101: and receiving a user registration application sent by a user network terminal to be registered.
Step S102: and sending the user registration application to the optical line terminal virtual node so that the optical line terminal virtual node completes registration on the user network terminal to be registered based on the user configuration information of the user network terminal to be registered and the user registration application to obtain the user network terminal, wherein the user configuration information of the user network terminal to be registered is stored in the optical line terminal virtual node.
Specifically, when the OLT virtualization system has a newly opened user network terminal, that is, a user network terminal to be registered, a worker configures the user information and service information corresponding to the user to an OLT virtual node through the EMS system, that is, stores the user configuration information of the user network terminal to be registered, and synchronously backs up the user configuration information to the entity OLT device. When the entity OLT equipment receives a user registration application sent by a user network terminal to be registered, namely, the user registration application is on-line for the first time, the entity OLT equipment forwards the user registration application and corresponding interaction information to the OLT virtual node, the entity OLT equipment does not perform any processing, the OLT virtual node interacts with the user network terminal to be registered according to stored user configuration information to complete registration, so that the user network terminal to be registered becomes a user network terminal in the OLT virtualization system, and the newly-opened user correspondingly becomes a stock user. And if the configuration of the user network terminal changes subsequently, the EMS system directly modifies the configuration information of the user network terminal stored in the OLT virtual node, completes the configuration adjustment, and synchronizes the latest user configuration information to the entity OLT equipment so as to call the user configuration information when a fault occurs and ensure that the information is updated in time.
In the specific implementation process, when the system works normally, if the user network terminal fails, the OLT virtualization node can transmit related warning information to the EMS system to remind the user of timely overhauling.
In this embodiment, the user network terminal of the newly opened user is registered, after the registration, the newly opened user becomes a stock user, and the user network terminal to be registered becomes a user network terminal of the stock user, so that when a system failure occurs, the normal operation of the user network terminals of all the stock users can be ensured by the method of this embodiment.
In the network device control method provided in this embodiment, when there is a communication failure between the optical line terminal device and an optical line terminal virtual node in the server, a first control operation is performed on the user network terminal according to first data information obtained by the optical line terminal device from the optical line terminal virtual node in a backup manner, second data information generated by the first control operation is stored, and when the optical line terminal device and the optical line terminal virtual node are restored to normal communication, the second data information is sent to the optical line terminal virtual node, so that the optical line terminal virtual node performs a second control operation on the user network terminal according to the second data information; because the data backup is carried out between the OLT virtual node and the entity OLT equipment, when the communication is failed, the entity OLT equipment can take over the control task of the OLT virtual node according to the backup data and backup the data generated by the control to the OLT virtual node after the communication is recovered, thereby solving the problem that the user network terminal cannot normally work due to the abnormal communication between the entity OLT equipment and the OLT virtual node, thereby influencing the use of the user, and realizing the effect of transferring the control function of the OLT virtual node on the user network terminal to the entity OLT equipment when the failure occurs; the invention provides a fault guarantee mechanism aiming at the communication fault between the entity OLT equipment and the OLT virtual node, which can effectively ensure the normal work of the user network terminal, prevent the influence on the use of the user and improve the user experience when the system is in fault.

The following describes in detail the network device control method provided in this embodiment with reference to fig. 5, where the method may include the following steps:
step S220: and backing up the first data information in the optical line terminal virtual node to optical line terminal equipment so that the optical line terminal equipment performs first control operation on a user network terminal according to the first data information when communication faults exist between the optical line terminal equipment and the optical line terminal virtual node, and stores second data information generated by the first control operation.
Specifically, before the entity OLT device and the OLT virtual node fail, when the OLT virtual node performs virtualization management and control on the user network terminal, the generated first data information is synchronously backed up to the OLT device, so that when a fault such as an optical cable between the OLT device and the server is interrupted or the OLT virtual node in the server fails occurs, the entity OLT device performs the virtualization management and control on the user network terminal by using the first data information, that is, a first control operation, and stores second data information correspondingly generated by the first control operation.
In the specific implementation process, when the entity OLT equipment manages and controls the user network terminal, the staff can check the fault reason, the use of the user is not influenced, and the user experience is improved.
Step S240: and when the communication between the optical line terminal equipment and the optical line terminal virtual node is recovered to be normal, receiving the second data information sent by the optical line terminal equipment, and performing second control operation on the user network terminal according to the second data information.
Specifically, after the communication between the entity OLT device and the OLT virtual node is restored to normal, the OLT virtual node acquires the fault recovery information from the EMS system, acquires the second data information from the entity OLT device, and then performs the second control operation on the user network terminal using the second data information, at this time, the entity OLT device is restored to the OMCI information transparent transmission channel, and the OLT virtual node continues to manage and control the user network terminal.
In one embodiment, before the step S220, the method may further include:
step S210: and before the communication fault exists between the optical line terminal equipment and the optical line terminal virtual node, performing third control operation on the user network terminal, and storing first data information generated by the third control operation.
Specifically, in a normal state, the OLT virtual node performs virtualization management and control on the user network terminal by using the entity OLT device as a channel, i.e., the transparent transmission OMCI interface, and stores correspondingly generated first data information, such as user information, user registration information, service information, ONT/ONU configuration information, and other interaction information. And the first data information is synchronously backed up to the entity OLT equipment, so that the entity OLT equipment calls the first data information to carry out materialized management and control on the user network terminal when a fault occurs.
In a specific implementation process, the OLT virtualization system carries out three stages from a normal state to a fault state and then to a fault recovery state, and correspondingly operates that the OLT virtual node carries out third control operation on the user network terminal, the entity OLT equipment carries out first control operation on the user network terminal, and then the OLT virtual node carries out second control operation on the user network terminal.
The data information is correspondingly stored in different stages, so that the integrity of the data of the whole OLT virtual system can be ensured, the data loss is prevented, and the normal work of the user network terminal is prevented from being influenced.
In another embodiment, the optical line terminal virtual node stores therein user configuration information of the to-be-registered user network terminal device. Before the step S210, the method may further include:
step S201: receiving a user registration application of a user network terminal to be registered, which is sent by the optical line terminal equipment;
step S202: and registering the user network terminal to be registered based on the user configuration information and the user registration application to obtain the user network terminal equipment.
Specifically, when a user terminal to be registered of a newly-opened user needs to be added, firstly, in the EMS system, a worker configures the user information and service information corresponding to the user to the OLT virtual node through the EMS system, that is, the user configuration information of the user network terminal to be registered is stored and is synchronously backed up to the entity OLT device. And then the entity OLT equipment forwards the user registration application, namely the first online application, sent by the user network terminal to be registered to the OLT virtual node. After receiving the first on-line application, the OLT virtual node interacts with the user network terminal to be registered based on the stored user configuration information and the first on-line application to complete registration, and the user network terminal to be registered of the new user becomes a user network terminal of the stock user. In the process, the entity OLT equipment plays a role of transmitting the OMCI interface channel.
In the network device control method provided in this embodiment, first data information in an optical line terminal virtual node of a server is backed up to an optical line terminal device, so that when a communication fault occurs 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 according to the first data information, and stores second data information that is generated correspondingly; and when the communication between the optical line terminal equipment and the optical line terminal virtual node is recovered to be normal, receiving the second data information sent by the optical line terminal equipment, and performing second control operation on the user network terminal according to the second data information, so that the normal work of the user network terminal is ensured when the communication between the optical line terminal equipment and the optical line terminal virtual node fails, the influence on the use of a user is prevented, the integrity of the data of an OLT virtualization system is also ensured, and the abnormal work of the user network terminal caused by the asynchronous data before and after the failure is prevented.
