Problems solved by technology

However, with the enhancement of the functions of the managed units and the increase of the number of managed units in the network, the amount of data that needs to be kept consistent will be very large, so it takes a long time to fully synchronize the data from the managed units at one time, increasing the system burden

[0047] Referring to Fig. 1, the first embodiment of the present invention comprises the following steps:

[0048] Step 101, the managed unit generates a data difference file according to its own data modification content in a predetermined period, that is, obtains the data changed in the predetermined period.

[0049]In step 101, the managed unit may generate the data difference file only after a self-defined trigger condition or a trigger condition agreed with the management unit is met. The trigger condition mentioned in this embodiment may be a timing trigger condition or a fixed event trigger condition. The timing trigger condition refers to the time period, such as every 8 hours, every 2 days or every week; the timing trigger condition can be a specific event, or a predetermined number of discrete events, such as the cumulative occurrence of n times of network configuration event.

[0050] Step 102, the managed unit reports the generated data difference file to the mana...

[0053] With reference to Fig. 2, the second embodiment of the present invention comprises the following steps:

[0054] In step 201, the management unit requests the managed unit to obtain a data difference file, that is, requests the managed unit to perform a data synchronization operation.

[0055] In step 201, the management unit may request the managed unit to obtain the data difference file only after a self-defined trigger condition or a trigger condition agreed with the management unit is met. The trigger condition mentioned in this embodiment may be a timing trigger condition or a fixed event trigger condition. The timing trigger condition refers to the time period, such as every 8 hours, every 2 days or every week; the timing trigger condition can be a specific event, or a predetermined number of discrete events, such as the cumulative occurrence of n times of network configuration event.

[0060] Referring to Fig. 3, the third embodiment of the present invention comprises the following steps:

[0061] Step 301, the management unit pre-subscribes to the managed unit for a data ready notification, that is, the managed unit is agreed to send a data ready notification to the management unit after generating a data difference file.

[0062] Step 302, the managed unit generates a data difference file according to its own data modification content within a predetermined period.

[0063] In step 302, the managed unit may generate the data difference file only after a self-defined trigger condition or a trigger condition agreed with the management unit is met. The trigger condition mentioned in this embodiment may be a timing trigger condition or a fixed event trigger condition. The timing trigger condition refers to the time period, such as every 8 hours, every 2 days or every week; the timing trigger condition can be a specific event, or a predetermined number of disc...

Abstract

The method comprises: a) the managed unit generates the data difference file according to the data modification content in the preset stage; b) the managed unit reports the data difference file to the managing unit. The invention only synchronizes the data difference file to the managing unit, but not synchronizes all data file to the managing unit so as to greatly reduce the quantity of synchronizing data. The invention also provides a synchronizing process of multi kinds of data and multi trigger modes of data synchronization.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a data synchronization method and system thereof. Background technique [0002] There are two logical entities in the existing network management system: the management unit and the managed unit. There is a many-to-many management relationship between them, and they interact through various forms such as control messages, notifications, and files. [0003] During the interaction process between the management unit and the managed unit, it is necessary to ensure the consistency of the data on the management unit and the managed unit. During the operation of the system, the communication between the management unit and the managed unit may fail, and the management unit and the managed unit themselves may fail, which will lead to data inconsistency between the two. [0004] In the prior art, whenever data synchronization is required, all data on the managed unit is synch...
