Abstract

A method, executed by a computer, includes sending a test media packet sequence to a client of a plurality of clients, receiving from the client a response packet sequence corresponding to the test media packet sequence, comparing the test media packet sequence to the response packet sequence to determine a quality of service score for the client, and notifying the client of the quality of service score. A computer system and computer program product corresponding to the above method are also disclosed herein.

Claims

1. A method, executed by a computer, the method comprising:

sending, from a conference manager, a test media packet sequence to a client of a plurality of clients;

receiving from the client a response packet sequence corresponding to the test media packet sequence;

comparing the test media packet sequence to the response packet sequence to determine a quality of service score for the client, wherein comparing the test media packet sequence to the response packet sequence comprises comparing a test file comprised of the test media packet sequence to a response file comprised of the response packet sequence, wherein the test file and the response file are stored on the conference manager and compared using the conference manager; and

notifying the client of the quality of service score.

2. The method of claim 1, wherein the quality of service score is based on one or more quality of service metrics selected from the group consisting of a response time metric, a jitter metric, a packet loss metric, a round-trip delay time metric, and a latency metric.

4. The method of claim 1, wherein the test media packet sequence comprises a media file having an audio portion and video portion.

5. The method of claim 1, further comprising suggesting to a user of the client to join a conference in a quality of service mode.

6. The method of claim 5, wherein the quality of service mode is selected from the group consisting of a high quality video mode, a low quality video mode, and an audio-only mode, based on the quality of service score of the client.

7. The method of claim 1, wherein notifying the client of the quality of service score comprises displaying to a user of the client the quality of service score.

3. (canceled)

8. A computer system comprising:

one or more computer processors;

one or more computer readable storage media;

program instructions stored therein for execution by at least one of the one or more computer processors, the program instructions comprising instructions to;

send, from a conference manager, a test media packet sequence to a client of a plurality of clients;

receive from the client a response packet sequence corresponding to the test media packet sequence;

compare the test media packet sequence to the response packet sequence to determine a quality of service score for the client, wherein comparing the test media packet sequence to the response packet sequence comprises comparing a test file comprised of the test media packet sequence to a response file comprised of the response packet sequence, wherein the test file and the response file are stored on the conference manager and compared using the conference manager; and

notify the client of the quality of service score.

9. The computer system of claim 8, wherein the quality of service score is based on one or more quality of service metrics selected from the group consisting of a response time metric, a jitter metric, a packet loss metric, a round-trip delay time metric, and a latency metric.

11. The computer system of claim 8, wherein the test media packet sequence comprises a media file having an audio portion and video portion.

12. The computer system of claim 8, further comprising instructions to suggest to a user of the client to join a conference in a quality of service mode.

13. The computer system of claim 12, wherein the quality of service mode is selected from the group consisting of a high quality video mode, a low quality video mode, and an audio-only mode, based on the quality of service score of the client.

14. The computer system of claim 8, wherein instructions to notify the client of the quality of service score comprise instructions to display to a user of the client the quality of service score.

10. (canceled)

15. A computer program product comprising:

a computer readable storage medium and program instructions stored on the computer readable storage medium, the program instructions comprising instructions to;

send, from a conference manager, a test media packet sequence to a client of a plurality of clients;

receive from the client a response packet sequence corresponding to the test media packet sequence;

compare the test media packet sequence to the response packet sequence to determine a quality of service score for the client, wherein comparing the test media packet sequence to the response packet sequence comprises comparing a test file comprised of the test media packet sequence to a response file comprised of the response packet sequence, wherein the test file and the response file are stored on the conference manager and compared using the conference manager; and

notify the client of the quality of service score.

16. The computer program product of claim 15, wherein the quality of service score is based on one or more quality of service metrics selected from the group consisting of a response time metric, a jitter metric, a packet loss metric, a round-trip delay time metric, and a latency metric.

18. The computer program product of claim 15, wherein the test media packet sequence comprises a media file having an audio portion and video portion.

19. The computer program product of claim 15, further comprising instructions to suggest to a user of the client to join a conference in a quality of service mode.

20. The computer program product of claim 19, wherein the quality of service mode is selected from the group consisting of a high quality video mode, a low quality video mode, and an audio-only mode, based on the quality of service score of the client.
