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, wherein the test media packet sequence comprises a media file having an audio portion and video portion, and wherein the plurality of clients are remote from the conference manager;

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 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, 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, and 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;

notifying the client of the quality of service score; and

responsive to a client joining a conference, placing the client in a quality of service mode according to the quality of service score of the client, 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, wherein placing the client in a quality of service mode comprises displaying on the client the quality of service score.
