In order to make the embodiments of the present invention more clearly understood, the preferred embodiments of the embodiments of the present invention are provided below.

The preferred embodiment provides a method and system for maintaining master data consistency in a PTN device.

The preferred embodiment relates to data consistency maintenance of the main control board of the PTN transmission device, and in particular, to maintaining and repairing the main control configuration data in the PTN network device without interrupting the service, and ensuring that the device data and the network management data are consistent. .

Two systems and methods in the background art, the first is to control the synchronization mechanism between the primary and backup data, and the second is to use the server for data synchronization. None of them involves data synchronization and consistency maintenance between multiple formats of data, especially the method of providing inconsistent real-time monitoring, and does not provide an automatic synchronization solution when data is inconsistent.

In the above-mentioned background, and in the existing network environment of the transmission device, the present invention proposes a real-time monitoring device data consistency under the premise of not interrupting the existing service as much as possible, and adopts corresponding when the data is inconsistent. The measures are quickly repaired to ensure the healthy and stable operation of the equipment.

The preferred embodiment provides a method and system for consistency checking and maintenance of data sources between different data formats. Through the method and the system, the user can monitor the device data in a real-time manner. If the inconsistency is found, the automatic data synchronization can be performed in a manner that minimizes the impact on the existing network service, and the data consistency between the device and the network management system is ensured.

The preferred embodiment adopts the following technical solutions, including the following steps:

Step A, the data model on the device:

The configuration data on the device can be delivered from the NMS or through the CLI. Therefore, the Agent component must be added to the device, as shown in Figure 2 (showing the simple interaction between three data). The data from these two configuration sources is configured. The Agent component must provide the following features:

1. Configuration data delivered by the NMS.

2. The data configured by the CLI is the network management data format and is saved in the library.

3. The Agent component must notify the network management or device running data in real time when the data changes.

The Agent component is also the key to achieving consistent maintenance and repair.

Step B, data consistency detection:

On the U2000, you can easily check whether the current device data is consistent. If the data is inconsistent, you can check which configuration data is inconsistent, so that you can determine the approximate synchronization policy.

Step C, synchronization mechanism

There are a total of 3 configuration data, which can be synchronized in pairs (see Figure 2), and the consistency of the three configuration data is realized by two-two synchronization. In theory, consistently maintaining the consistency of three data based on any single data.

For example, based on the operating data of the device, consistency maintenance is performed. Then, the operation data of the device is batch-synchronized to the database maintained by the agent by the command, and then the network management uploads the database of the agent to the network management system by uploading, and overwrites the original data of the network management to realize the consistency of the three types of data. Of course, these synchronous operations, after the user selects a consistent maintenance strategy, can be automatically completed.

The preferred embodiment provides a method and system for data consistency check and maintenance. The network management process of the agent component and the device is used to monitor the device data in real time. When the inconsistency is found, a fast and effective repair method is provided, which is automatically completed for the user. Consistent maintenance to ensure equipment reliability. The preferred embodiment will be further described below in conjunction with specific embodiments.

The relationship between the three configuration data that needs to maintain consistency is shown in Figure 2. That is, the three data can only be synchronized in two or two, and the network management system cannot directly synchronize with the running data of the device.

Scenario 1, data inconsistency monitoring:

Figure 3 shows the process of data inconsistency monitoring, the specific processing steps:

310: The user configures the service through the CLI, which causes the device running data to change.

320: The service processing module notifies the agent component of the configuration report, and the agent component converts the corresponding configuration data into a corresponding service data structure, and then saves the data into the library. At the same time, notify the network management device that there is data change.

330: After receiving the data change notification, the network management system displays data inconsistency information on the user interface, and can view which information is inconsistent. Network management and device data synchronization will continue to be explained in the following example 3.

Scenario 2: The main synchronization process is based on network management data:

Figure 4 shows the data synchronization process based on network management data when the data is inconsistent. After the user selects a good policy, these synchronization processes automatically synchronize, without user intervention, and synchronization ensures that the existing network services are not interrupted as much as possible.

410: The user network management interface finds data inconsistency information, and the network management interface selects network management data as the main data synchronization.

420: The network management system reads the data from the network management database, and delivers the service configuration data to the device in a specific order.

430: The Agent component processes the data sent by the network management system in full, and analyzes and compares the data with the data of the agent to obtain inconsistent configuration data.

440: The Agent component maps the inconsistent configuration data to the service data model of the device according to the interface.

450: The agent component delivers the data obtained by the mapping to the device service module according to the business rule.

460: The device service processing module receives and processes the service configuration data, changes the current state of the device, and simultaneously writes the device operation data.

470: All data is successfully delivered, and the synchronization operation is completed, which ensures the consistency of the three data.

In particular, there may be cases where the data is sent out. The Agent component must guarantee the atomic operation of each configuration data modification to ensure that it can fall back to the original state even if it fails.

Scenario 3: The device running data is the main synchronization process:

Figure 5 shows the data synchronization process based on the device operation data when the data inconsistency is detected. After the user selects a good policy, these synchronization processes are automatically synchronized, and no user intervention is required. Because the running data is the main one, the existing network service will not be affected.

510: The user network management interface finds data inconsistency information, and the network management interface selects the device running data as the main data synchronization.

520: The device service module reads the device running data, and encapsulates the corresponding interface packet, and reports the packet to the agent component.

530: The Agent component processes each received message, converts the mapping into an internal data structure, and clears the original data, and stores the newly converted data into the database.

540: The agent component reports all the data reported by the device, and after the storage is successful, the network management is actively notified to synchronize the data.

550: The network management system sends a synchronization command to the agent component, and the synchronization command needs to be sent multiple times, and each service data is synchronized.

560: The agent component receives the synchronization command, reads the corresponding service data, and reports the packet to the network management system.

570: The network management saves the data reported by the agent in the manner of overlaying the storage.

580: After all the business data is synchronized, the synchronization process ends and the three data are consistent.
