Abstract

An arrangement is provided for evaluating the performance of different types of communication paths which may be set up in a multi-service network, wherein different paths may comprise interconnections of different single communication services such as wireless and wireline telephone systems and internet access systems. Data pertaining to at least one common performance parameter is acquired for each type of communication path, and a performance graph for each type of path is constructed from the data respectively acquired therefor. The performance graphs for respective communication paths are evaluated and compared with one another, to provide information useful for improving network performance.

Claims

1. In a multi-service network comprising a number of different communication services, and operable to establish selected different types of homogeneous and heterogeneous communication paths, a network performance analysis method comprising the steps of:

acquiring data pertaining to at least one common performance parameter for each of said types of communication paths;

constructing a performance graph for each of said types of communication paths from the data respectively acquired therefor; and

comparing the performance graph of any one of said communication paths of said multi-service network with the performance graph of any other of said communication paths to generate specified information pertaining to performance of said network.

2. The method of claim 1 wherein:

said at least one performance parameter comprises a representation of the number of connections successfully completed, relative to a specified number of connections attempted.

3. The method of claim 1 wherein:

said method further includes the step of altering a characteristic of said multi-service network, and employing said comparing step to determine effects of said alteration on respective communication paths of said network.

4. The method of claim 1, wherein said data acquisition step comprises:

selectively operating said multi-service network to establish communication paths of each of said different types; and

measuring the values of said respective performance parameters for each of said established communication paths.

5. The method of claim 1, wherein:

said data acquisition step comprises accessing a database comprising connection charging records.

6. The method of claim 1, wherein:

said data acquisition step comprises accessing a centralized connection information database.

7. The method of claim 1, wherein:

said multi-service network includes at least one service selected from a group comprising wireless, wireline and internet communication services.

8. The method of claim 1 wherein said data acquisition step comprises:

for a selected type of communication path, initiating efforts to implement a series of test connections to set up communication paths between a specified central location and each of a number of preselected locations; and

recording the results of said test connection efforts for use in detecting an error in said selected type of communication path.

9. In a multi-service network comprising a number of different communication services, a method for analyzing performance of said network comprising the steps of:

operating said multi-service network to establish selected homogeneous and heterogeneous communication paths within said network;

acquiring data pertaining to at least one common performance parameter for each of said established communication paths;

constructing a performance graph for each of said established communication paths from the data respectively acquired therefor; and

employing respective performance graphs to selectively analyze performance of said network.

10. The method of claim 9 wherein:

said at least one performance parameter comprises a representation of the number of connections successfully completed, relative to a specified number of connections attempted.

11. The method of claim 10 wherein:

said step of employing performance graphs comprises comparing the performance graph of any one of said established communication paths with the performance graph of any other of said established communication paths to generate specified information pertaining to performance of said network.

12. The method of claim 11 wherein:

said network is operated to establish first and second communication paths of the same type, and data for constructing performance graphs for said first and second performance graphs, respectively, is acquired while said first and second graphs are being operated under selectively different conditions.

13. The method of claim 10, wherein:

for a selected type of communication path, said network attempts to implement a series of test connections to set up specific communication paths between a specified central location and each of a number of preselected locations; and

the results of said attempts are recorded for each of said test connections and used to construct performance graphs respectively pertaining thereto, the performance graphs being used to detect errors in said selected path.

14. The method of claim 10 wherein said data acquisition step comprises:

measuring the values of said performance parameters for each of said established communication paths.

15. The method of claim 10 wherein:

said data acquisition step comprises accessing a database comprising connection charging records.

16. The method of claim 10 wherein:

said multi-service network includes at least one service selected from a group comprising wireless, wireline and internet communication services.

18. The apparatus of claim 17 wherein:

said at least one performance parameter comprises a representation of the number of connections successfully completed, relative to a specified number of connections attempted.

19. The apparatus of claim 17 wherein:

said processor is adapted to generate information pertaining to effects on performance of said network resulting from alteration of a specified characteristic thereof.

20. The apparatus of claim 17 wherein:

said multi-service network includes at least one service selected from a group comprising wireless, wireline and internet communication services.

17. In a multi-service network comprising a number of different communication services, and operable to establish selected different types of homogeneous and heterogeneous communication paths, apparatus for analyzing performance of said network comprising:

a data base containing data pertaining to at least one common performance parameter for each of said types of communication paths;

a processor disposed to construct a performance graph for each of said types of communication paths from data respectively pertaining thereto which is contained in said database; and

said processor is further disposed to compare the performance graph of any one of said communication paths of said multi-service network with the performance graph of any other of said communication paths to generate specified information pertaining to performance of said network.
