Method, system, and computer program product for reconstructing a data stream

1. A method for reconstructing a data stream, the method comprising:

listening to an original data stream;

extracting messages from the original data stream;

determining statistical data from the extracted messages;

creating a reconstructed data stream using the statistical data;

determining a sequence of messages from the extracted messages;

creating model data from the statistical data;

creating a sequence of data packets from the sequence of messages and model data; and

outputting the sequence of data packets as the reconstructed data stream.

2. The method of claim 1 , wherein the method is implemented by an application plug-in.

3. The method of claim 1 , wherein the original data stream comprises one or more messages between a data producer and a data consumer.

4. The method of claim 1 , wherein the original data stream comprises messages in an industry standard communication protocol.

5. The method of claim 4 , wherein the industry standard communication protocol comprises at least one of:

extensible markup language;

document type definition;

web services;

remote method invocation common object request broker architecture;

message queue middleware; and

hypertext transfer protocol.

6. The method of claim 1 , wherein the statistical data comprises at least one of:

a low value;

a high value;

an average value;

a standard deviation; and

a variance.

7. The method of claim 1 , further comprising:

reconstructing a data format from the extracted messages.

8. The method of claim 1 , wherein creating the reconstructed data stream further comprises:

validating the sequence of data packets by comparing the sequence of data packets to additional extracted messages from the data stream; and

updating the model data and sequence of messages based upon the validation.

9. The method of claim 1 , wherein the reconstructed data stream is used for at least one of:

a test;

a simulation;

a system analysis;

a model of a data producer;

a model of a data consumer;

a data stream supplement;

a data stream replacement; and

reverse engineering of a system.

10. A system for reconstructing a data stream, the system comprising:

a data producer;

a data consumer; and

a data stream reconstructor, the data stream reconstructor performing:

listening to an original data stream, the original data stream comprised of one or more messages between the data producer and the data consumer;

extracting messages from the original data stream;

determining statistical data from the extracted messages;

creating a reconstructed data stream using the statistical data;

determining a sequence of messages from the extracted messages;

creating model data from the statistical data;

creating a sequence of data packets from the sequence of messages and model data; and

outputting the sequence of data packets as the reconstructed data stream.

11. The system of claim 10 , wherein the data stream reconstructor is implemented by an application plug-in.

12. The system of claim 10 , wherein the original data stream comprises messages in an industry standard communication protocol.

13. The system of claim 10 , further comprising:

reconstructing a data format from the extracted messages.

14. The system of claim 10 , wherein creating the reconstructed data stream further comprises:

validating the sequence of data packets by comparing the sequence of data packets to additional extracted messages from the data stream; and

updating the model data and sequence of messages based upon the validation.

15. A computer program product for reconstructing a data stream, the computer program product comprising:

a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for facilitating a method comprising:
