Abstract

Systems, methods, and software are disclosed for synchronizing data among network elements of a telecommunication management network. In a data synchronization system, a mapping system receives a first data set from a first network element and receives a second data set from a second network element. The mapping system processes the first data set to identify a first object, and processes the first object based on mapping rules to identify an associated second object in the second data set, and map the first object and the second object. A comparison system then processes the first object and the second object as mapped to identify differences between the objects, and generates information indicating the differences. An alignment system processes the first object and the information indicating the differences to generate new object data used to adjust the first object stored in the first network element.

Claims

1. A method of synchronizing network management data among network elements of a telecommunication management network, the method comprising the steps of:

receiving a first data set from a first network element of the telecommunication management network;

receiving a second data set from a second network element of the telecommunication management network;

processing the first data set to identify a first object in the first data set;

processing the first object and the second data set based on mapping rules to identify a second object in the second data set associated with the first object in the first data set;

processing the first object and the second object based on the mapping rules to map the first object to the second object;

processing the first object and the second object as mapped to identify differences between the first object and the second object; and

generating information indicating the differences between the first object and the second object.

2. The method of claim 1 further comprising the step of:

processing the first object and the information indicating the differences to generate new object data;

generating commands based on the new object data to adjust the first object stored in the first network element; and

transmitting the commands to the first network element.

3. The method of claim 2 further comprising the step of:

generating a human-readable report based on the information indicating the differences between the first object and the second object.

4. The method of claim 1 further comprising the step of generating the mapping rules in extensible markup language (XML) or another declarative language.

5. The method of claim 4 wherein at least one of the mapping rules identifies the second object in the second data set associated with the first object in the first data set.

6. The method of claim 4 wherein at least one of the mapping rules defines direct mapping between an attribute of the first object and a corresponding attribute of the second object.

7. The method of claim 4 wherein:

if an attribute of the first object does not have a corresponding attribute in the second object, then at least one of the mapping rules defines how to locate a third object that includes an attribute that corresponds with the attribute of the first object.

8. The method of claim 4 wherein at least one of the mapping rules defines mapping between one attribute of the first object and multiple attributes of the second object.

9. The method of claim 4 wherein at least one of the mapping rules defines mapping between an attribute value of the first object and an attribute value of the second object, wherein the attribute values are of a different type.

10. A data synchronization system for a telecommunication management network, the data synchronization system comprising:

a mapping system that receives a first data set from a first network element of the telecommunication management network, receives a second data set from a second network element of the telecommunication management network, processes the first data set to identify a first object in the first data set, processes the first object and the second data set based on mapping rules to identify a second object in the second data set associated with the first object in the first data set, and processes the first object and the second object based on the mapping rules to map the first object to the second object; and

a comparison system that processes the first object and the second object as mapped to identify differences between the first object and the second object, and generates information indicating the differences between the first object and the second object.

11. The data synchronization system of claim 10 further comprising:

an alignment system that receives the information indicating the differences between the first object and the second object, and processes the first object and the information indicating the differences to generate new object data; and

a command system that receives the new object data, generates commands based on the new object data to adjust the first object stored in the first network element, and transmits the commands to the first network element.

12. The data synchronization system of claim 11 further comprising:

a reporting system that receives the information indicating the differences between the first object and the second object, and generates a human-readable report.

13. The data synchronization system of claim 10 wherein the mapping rules are written in extensible markup language (XML) or another declarative language.

14. The data synchronization system of claim 13 wherein:

at least one of the mapping rules identifies the second object in the second data set associated with the first object in the first data set;

at least one of the mapping rules defines direct mapping between an attribute of the first object and a corresponding attribute of the second object;

if an attribute of the first object does not have a corresponding attribute in the second object, then at least one of the mapping rules defines how to locate a third object that includes an attribute that corresponds with the attribute of the first object;

at least one of the mapping rules defines mapping between one attribute of the first object and multiple attributes of the second object; and

at least one of the mapping rules defines mapping between an attribute value of the first object and an attribute value of the second object, wherein the attribute values are of a different type.

15. A software product for synchronizing network management data among network elements of a telecommunication management network, the software product comprising:

mapping instructions when executed by a processing system that receive a first data set from a first network element of the telecommunication management network, receive a second data set from a second network element of the telecommunication management network, process the first data set to identify a first object in the first data set, process the first object and the second data set based on mapping rules to identify a second object in the second data set associated with the first object of the first data set, and process the first object and the second object based on the mapping rules to map the first object to the second object;

comparison instructions when executed by the processing system that process the first object and the second object as mapped to identify differences between the first object and the second object, and generate information indicating the differences between the first object and the second object; and

computer-readable media that stores the mapping instructions and the comparison instructions.

16. The software product of claim 15 further comprising:

alignment instructions when executed by the processing system that receive the information indicating the differences between the first object and the second object, and process the first object and the information indicating the differences to generate new object data; and

command instructions when executed by the processing system that receive the new object data, generate commands based on the new object data to adjust the first object stored in the first network element, and transmit the commands to the first network element.
