The master control system can identify the model type of the secondary control system and acquire a pre-constructed heterogeneous model mapping table from the cloud server to realize plug and play.
In specific implementation, the method for forward data synchronization of the heterogeneous network information model database in the embodiment of the invention comprises the following steps:
when the network information model database of the main control system changes, the main control system maps the change into the change of the network information model database of the secondary control system according to the mapping relation between the network information model of the main control system and the network information model of the secondary control system, and triggers the network information model database of the secondary control system to synchronously update;
specifically, the method for forward data synchronization of the heterogeneous network information model database according to the embodiment of the invention comprises the following steps:
1. the master control system monitors a read-write module of the network information model database of the master control system and reads the operation of the read-write module on the network information model database;
2. the operation input heterogeneous model mapping tables are used for obtaining output results, the output results are sent to a secondary management and control system, and the output results carry the network information model version identification used by the operation of the results;
3. and the secondary management and control system updates the network information model database of the system according to the received output result.

Because a main control system possibly corresponds to a plurality of secondary control systems, the situation that the main control system sends an output result in error can be effectively avoided by setting the network information model version identifier.
The method for forward data synchronization of heterogeneous network information model databases will be explained and illustrated in detail by way of a specific example:
1. the master control system monitors that the Model database operation module completes a new object instance action, a logic ending point Logical Termination Point is added, the object path of the instance is model_Base, namely, forward/forward connection structure/logicaltermination point/_serverltp, and the logic ending point is provided with an attribute_serverltp, and the object path of the attribute is model_Base, namely, forward/forward connection structure/logicaltermination point/_serverltp.
2.

3. And the master control system sends the mapping result of the last step to the secondary control system, and the secondary control system takes the received mapping result as the input of the network information model database operation module thereof, executes the synchronous request and completes the synchronous action.
In specific implementation, the method for reverse data synchronization of the heterogeneous network information model database in the embodiment of the invention comprises the following steps: when the network information model database of the secondary management and control system changes, the primary management and control system receives the change sent by the secondary management and control system, maps the change into the change of the network information model database of the primary management and control system according to the mapping relation between the network information model of the primary management and control system and the network information model of the secondary management and control system, and triggers the network information model database of the primary management and control system to synchronously update.
Specifically, the method for reverse data synchronization of heterogeneous network information model databases according to the embodiment of the invention comprises the following steps:
1. the secondary management and control system monitors a read-write module of a network information model database of the system, and reads the operation of the read-write module on the network information model database;
2. the operations are sent to a master control system, and the operations carry the version identification of the network information model of the secondary control system;
3. the master control system inputs the received operation to the heterogeneous model mapping table to obtain an output result, and updates the network information model database of the master control system according to the received output result.
According to the embodiment of the invention, when the change is sent to the main control system, the network information model version identification of the secondary control system is carried, and the main control system verifies the network information model version identification, so that the main control system can better position the changed secondary control system.
When the number of the secondary management and control systems is multiple and the network information model database of one secondary management and control system is changed, the primary management and control system receives the change sent by the changed secondary management and control system, and maps the change into the network information model database of the primary management and control system and the network information model databases of other secondary management and control systems according to the mapping relation between the network information model of the primary management and control system and the network information model database of each secondary management and control system, and triggers the network information model databases of the primary management and control system and the network information model databases of other secondary management and control systems to update synchronously.
That is, when there are a plurality of secondary management and control systems, when the network information model database of a certain secondary management and control system changes, the primary management and control system needs to synchronize the operation on its own and other secondary management and control systems.
Namely, the data synchronization method of the heterogeneous network information model database in the embodiment of the invention comprises forward data synchronization and reverse data synchronization to realize bidirectional synchronization, and can realize data coordination of the multi-heterogeneous management and control system through pairwise interconnection of the forward data synchronization and the reverse data synchronization.
When the number of the secondary management and control systems is multiple and the network information model database of one secondary management and control system is changed, the primary management and control system receives the change sent by the changed secondary management and control system and the network information model version identification of the secondary management and control system, and the primary management and control system respectively maps the change into the change of the network information model database of the primary management and control system and the network information model database of other secondary management and control systems according to the mapping relation between the network information model of the primary management and control system and the network information model of each secondary management and control system, carries the network information model version identification of each secondary management and control system, and triggers the network information model databases of the primary management and control system and the network information model databases of other secondary management and control systems to synchronously update.
That is, when the number of the secondary management and control systems is multiple, the version identifiers of the network information models of the corresponding secondary management and control systems need to be carried when the secondary management and control systems are synchronized, so that the accuracy and consistency of synchronization are effectively ensured.
Because the SDN controller and the network element management system have the same functions and perform network resource scheduling and control, the embodiment of the invention only uses the network element management system as an example to describe the method of the invention, and specifically, the embodiment of the invention performs network information model database synchronization by using a plurality of management and control systems which simultaneously control a group of network devices, and specifically includes:
