Abstract

A method and system for the efficient determination of quality of service parameters for multimedia files accessed during operation of a specified multimedia application. Operation of the specified multimedia application is initiated. During operation, the multimedia application accesses multimedia files by reading the data stored in those files. The multimedia files are identified, and each read performed by the multimedia application is analyzed while each multimedia file is accessed. Quality of service parameters for each multimedia file may be automatically determined utilizing the analysis of each read of a multimedia file performed by the multimedia application.

Claims

1. A method in a data processing system for efficiently determining quality of service parameters for a plurality of multimedia files accessed during operation of a specified multimedia application, said data processing system including a storage device, said method comprising the steps of:

initiating operation of said specified multimedia application;

identifying each of said plurality of multimedia files accessed by said specified multimedia application, wherein said specified multimedia application reads data stored in each of said plurality of multimedia files;

analyzing each read performed by said specified multimedia application while said specified multimedia application is accessing each of said plurality of multimedia files; and

automatically determining quality of service parameters for each of said plurality of multimedia files utilizing said analysis of each read performed by said specified multimedia application.

2. The method in a data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 1, wherein said step of automatically determining quality of service parameters further includes the steps of:

determining a size of said each read performed by said specified multimedia application; and

determining a time when said each read performed by said specified multimedia application occurred.

3. The method in a data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 2, further including the step of determining a read throughput for each of said plurality of multimedia files utilizing said determined size of said each read and said determined time when said each read occurred.

4. The method in a data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 3, further including the step of storing said read throughput within said storage device.

5. The method in a data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 4, further comprising the step of determining which of said plurality of multimedia files were accessed by said specified multimedia application concurrently utilizing said determined time when said each read occurred.

6. The method in a data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 5, further comprising the step of storing said determining of which of said plurality of multimedia files were accessed by said specified multimedia application concurrently in said storage device.

7. A data processing system for efficiently determining quality of service parameters for a plurality of multimedia files accessed during operation of a specified multimedia application, said data processing system including a storage device, comprising:

means for initiating operation of said specified multimedia application;

means for identifying each of said plurality of multimedia files accessed by said specified multimedia application, wherein said specified multimedia application reads data stored in each of said plurality of multimedia files;

means for analyzing each read performed by said specified multimedia application while said specified multimedia application is accessing each of said plurality of multimedia files; and

means for automatically determining quality of service parameters for each of said plurality of multimedia files utilizing said analysis of each read performed by said specified multimedia application.

8. The data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 7, wherein said means for automatically determining quality of service parameters further comprises:

means for determining a size of said each read performed by said specified multimedia application; and

means for determining a time when said each read performed by said specified multimedia application occurred.

9. The data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 8, further comprising means for determining a read throughput for each of said plurality of multimedia files utilizing said determined size of said each read and said determined time when said each read occurred.

10. The data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 9, further comprising means for storing said read throughput within said storage device.

11. The data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 10, further comprising means for determining which of said plurality of multimedia files were accessed by said specified multimedia application concurrently utilizing said determined time when said each read occurred.

12. The data processing system for efficiently determining quality of service parameters associated with a plurality of multimedia files according to claim 11, further comprising means for storing said determining of which of said plurality of multimedia files were accessed by said specified multimedia application concurrently in said storage device.
