Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
As shown in fig. 1, the vtolt System is composed of a physical Device Layer (dlolt, Distributed OLT), an ONU, a virtualized Device Layer (VDL, Virtual Device Layer), and an EMS (Element Management System)/SDN controller Layer, and the virtualized Device Layer extracts the OMCI Management function of the ONU on the original OLT Device to form a componentized and standardized virtualized Device Layer. The virtualization layer has the advantages that the decoupling of the OLT and the ONU equipment is realized, all OLT equipment in the whole network needs to be upgraded at the same time when the ONU equipment is upgraded in the prior art, the network deployment is in charge, and after the virtualization layer is adopted, the ONU equipment is upgraded only by carrying out software upgrade on the level virtualization layer, so that the operation and maintenance workload is greatly simplified. The virtualization layer comprises a management and control processing subsystem and a Virtual OMCI (OMCI) subsystem, wherein the vOMCI subsystem receives messages of the management and control processing subsystem, converts the messages into standard OMCI messages, and transmits the standard OMCI messages to the ONU equipment through an interface with the dOLT equipment to realize the management of the ONU equipment, and interfaces between the vOMCI subsystem and the management and control processing subsystem (receiving EMS/SDN controller messages, converting the messages into the vOMCI messages and transmitting the vOMCI messages to the vOMCI subsystem) and the dOLT equipment (physical OLT equipment, and transmitting the OMCI messages transmitted by the vOMCI subsystem to the ONU equipment) are standard interfaces. The management and control processing subsystem is a data core and is responsible for processing relevant business logic of a manufacturer and transmitting instructions to the vOMCI system through a standardized interface.
As shown in fig. 2, the process of changing the offline configuration of the ONU defined in the china mobile standard includes: when the ONU is off-line and the ONU configuration is modified through the EMS/SDN controller, the configuration information is issued to a control processing subsystem (also called a manufacturer control module), the control processing subsystem stores the configuration when judging that the ONU is not on-line, and issues an instruction to inform the vOMCI subsystem to forcibly clear the ONU OMCI MIB (Management Information Base), when the ONU equipment is on line and the authentication is passed, the management and control processing subsystem informs the vOMCI subsystem that the ONU is on line and checks the MIB synchronization state, because the ONU OMCI MIB is cleared, therefore, the vOMCI subsystem checks that the MIB synchronous codes are inconsistent, an MIB synchronous state (not synchronous) is returned to the management processing subsystem, the management and control processing subsystem issues an instruction again to inform the vOMCI subsystem to force MIB synchronization, the vOMCI subsystem starts an MIB synchronous flow, the management and control processing subsystem issues all ONU configuration information again, and reports ONU on-line information.
There are many efficiency problems in the above procedure, for example:
1, when an EMS/SDN controller frequently updates ONU configuration, a management processing subsystem frequently issues an ONU OMCI MIB clearing instruction to a vOMCI subsystem;
2, after the ONU is on line, the management and control processing subsystem needs to check the MIB synchronization state of the vOMCI subsystem and issues an instruction for clearing the ONU OMCI MIB again.
Because the virtualization device layer needs to manage concurrent requests of a large number of ONU devices at the same time, the requirement on efficiency is extremely high, and therefore, the processing flow defined in the specification has many places that can be optimized.
Therefore, according to the technical scheme provided by the embodiment of the invention, the ONU configuration issuing process is further simplified by simplifying the ONU configuration changing process, the interaction between the management and control processing subsystem and the vOMCI subsystem is reduced, the processing time consumption can be reduced, and the processing efficiency of the whole virtualization equipment layer is improved.
Fig. 3 is a schematic flowchart of a method for managing an ONU configuration in an optical network unit according to an embodiment of the present invention, where the method is applied to a management and control processing subsystem of a virtualization device layer, and as shown in fig. 3, the method includes:
Wherein, the setting the MIB issue status of the OUN as undelivered includes:
checking the issuing state of the management information base of the ONU, and modifying the issuing state of the MIB to be undelivered when the issuing state of the MIB is issued; and when the MIB issuing state is undelivered, not modifying the issuing state of the MIB.
And the configuration information of the OUN is the configuration information firstly modified or modified again by the user in the EMS/SDN controller.
Wherein, the method also comprises:
when the ONU is on line, checking the MIB issuing state;
when the MIB issuing state is not issued, issuing a forced MIB synchronization instruction to a virtual optical network unit management control interface (vOMCI) subsystem;
and all the stored configuration information of the ONU is issued to the vOMCI subsystem, so that the vOMCI subsystem issues all the configuration information to the ONU.
Wherein, the method also comprises:
and after the vOMCI subsystem issues all the configuration information to the ONU, setting the MIB issuing state as issued, and reporting an ONU on-line message to the EMS/SDN.
After the ONU is online, the method further comprises the following steps: and when the MIB issuing state is issued, directly reporting an ONU online message to the EMS/SDN.
Fig. 4 is a schematic flowchart of a method for managing an ONU configuration, where the method is applied to a virtualization device layer, where the virtualization device layer includes a management and control processing subsystem and a viomci subsystem, and as shown in fig. 4, the method includes:
Wherein, the method also comprises:
after the vOMCI subsystem issues all the configuration information to the ONU, the management and control processing subsystem sets the MIB issuing state as issued and reports ONU online information to the EMS/SDN.
After the ONU is online, the method further includes:
and when the MIB issuing state is issued, the management and control processing subsystem directly reports an ONU online message to the EMS/SDN.
Fig. 5 is a flowchart illustrating a method for managing an ONU configuration in an optical network unit according to another embodiment of the present invention. The present embodiment is applied to the system architecture shown in fig. 1.
In this embodiment, an MIB issue status concept of the ONU is introduced into the management and control processing subsystem of the virtualization device layer. After the ONU is added, when the EMS/SDN controller modifies the ONU configuration for the first time during the period of ONU off-line, the management and control processing subsystem does not issue an instruction for clearing the ONU OMCI MIB to the vOMCI subsystem after receiving the instruction, but sets the MIB issuing state corresponding to the ONU in the management and control processing subsystem to be not issued, and stores the configuration information. When the EMS/SDN controller issues the ONU configuration modification command again, the management and control processing subsystem checks the MIB issuing state of the ONU, if the ONU is issued, the MIB issuing state is modified to be not issued, the configuration is stored, and if the ONU is not issued, the MIB issuing state is not modified, and the configuration information is directly stored. That is to say, during the period of offline of the ONU, the management and control management subsystem only modifies the MIB issuing state, and does not issue instructions to the vOMCI subsystem.
As shown in fig. 5, when an ONU is in an offline state and a user modifies ONU configuration on EMS/SDN, the method specifically includes:
step 501, an EMS/SDN issues the modified OUN configuration information to a management and control processing subsystem;
the modified OUN configuration information may be configuration information that is first modified or modified again by a user at the EMS/SDN controller.
Wherein, the setting the MIB issue status of the OUN as undelivered includes: when the MIB issuing state is issued, modifying the MIB issuing state to be not issued; and when the MIB issuing state is undelivered, the issuing state of the MIB does not need to be modified.
Specifically, in the prior art, when the ONU configuration is modified by the EMS/SDN controller, after configuration information is issued to the management and control processing subsystem, the management and control processing subsystem not only saves the configuration, but also needs to issue an instruction to notify the vcommi subsystem to clear the ONU OMCI MIB. In this embodiment, a user modifies the ONU configuration on the EMS/SDN, the EMS/SDN issues configuration information to the management and control module subsystem, and after the management and control module subsystem successfully stores the configuration information, the management and control module subsystem does not need to notify the vcommi subsystem to clear the ONU OMCI MIB, that is, the management and control module subsystem does not need to interact with the vcommi subsystem, but only needs to check and modify the MIB issuance state of the OUN.
According to the technical scheme provided by the embodiment of the invention, during the period of ONU off-line, a user can modify ONU configuration on EMS/SDN for many times, and step 501 and step 503 are repeated continuously, during this period, the management and control processing subsystem does not issue an instruction for clearing ONU OMCI MIB to the vOMCI subsystem, and the command interaction times between the management and control module subsystem and the vOMCI subsystem are reduced.
Fig. 6 is a flowchart illustrating a method for managing an ONU configuration in an optical network unit according to another embodiment of the present invention.
This embodiment further includes a processing procedure after the ONU is online based on the previous embodiment. After the ONU is on line, the management and control processing subsystem checks the MIB issuing state of the ONU, if the ONU is not issued, a forced MIB synchronization instruction is issued to the vOMCI subsystem, the vOMCI subsystem starts an MIB synchronization process and issues all ONU configuration information received from the management and control processing subsystem to the ONU in sequence, after the configuration issuing is finished, the management and control module subsystem sets the MIB issuing state to be issued, reports the ONU on-line information to EMS/SDN, and the ONU enters a normal working state.
As shown in fig. 6, when the ONU is online, the method specifically includes:
step 504, the management and control module subsystem checks the MIB issuing state of the ONU;
before the management and control module subsystem checks the MIB issuing state of the ONU, the ONU online process specifically includes: after the ONU equipment is accessed to the dOLT equipment, the ONU sends an application online message to the dOLT equipment; after receiving the ONU application online message, the dOLT equipment sends the ONU online message to the management and control module subsystem; and after receiving the ONU on-line message, the management and control module subsystem sends the ONU on-line message to the vOMCI subsystem.
And when the MIB issued status of the ONU is not issued, executing step 505, and when the MIB issued status of the ONU is issued, turning to step 510.
step 506, after the vOMCI subsystem receives the mandatory MIB synchronization instruction, starting an MIB synchronization process;
the MIB synchronization process is started, including MIB Reset and MIB Upload operations, for example, MIB Reset/MIB Upload messages are issued to the ONU by the olt, which is not described in detail in the prior art.
step 508, the viomci subsystem issues all the configuration information to the ONU;
509, the management and control processing subsystem sets the MIB issue status as issued;
and step 510, reporting an ONU online message to the EMS/SDN.
After receiving the ONU online message, the EMS/SDN can update the ONU to be in an online state.
Specifically, in the prior art, after the ONU is online, the management and control module subsystem issues an instruction to the viomci subsystem to check the MIB synchronization state, and then issues a forced MIB synchronization instruction if the viomci subsystem returns that the MIB state is not synchronized.
Therefore, according to the technical scheme provided by the embodiment of the invention, as the management and control processing subsystem stores the MIB issuing state of the ONU, after the ONU is on line, no instruction is required to be issued to the vOMCI subsystem to check the MIB synchronization state, the follow-up process can be directly issued according to the stored MIB issuing state, and the MIB interaction times between the management and control module subsystem and the vOMCI subsystem are reduced.
According to the technical scheme provided by the embodiment of the invention, when the virtualization device layer processes the ONU equipment online and offline requests in a centralized manner, the MIB issuing state of the ONU can be saved, and the number of times of interaction with the vOMCI subsystem is reduced, so that the pressure on the virtualization device layer is greatly reduced, the virtualization device layer can process the ONU online and offline requests in a centralized manner, the network response speed is improved, meanwhile, the service flow of the management and control module subsystem is also simplified, and the reliability and maintainability of the whole virtualization device layer can be improved.

and the management unit is used for setting the MIB issuing state of the OUN as undelivered.
Wherein, the management unit is specifically configured to: checking the issuing state of the management information base of the ONU, and modifying the issuing state of the MIB to be undelivered when the issuing state of the MIB is issued; and when the MIB issuing state is undelivered, not modifying the issuing state of the MIB.
And the configuration information of the OUN is the configuration information firstly modified or modified again by the user in the EMS/SDN controller.
