Abstract

A computer-implemented method, computer program product, and computing system is provided for managing quality of experience for communication sessions. In an implementation, a method may include analyzing network conditions relative to a plurality of codecs and a plurality of network paths. The method may also include determining a quality of experience associated with each of the plurality of codecs across each of the plurality of network paths. The method may further include transacting communication traffic using a codec-network path combination having a quality of experience above a predetermined threshold.

Claims

1. A computer-implemented method comprising:

analyzing, by a processor, network conditions relative to a plurality of codecs and a plurality of network paths;

determining a quality of experience associated with each of the plurality of codecs across each of the plurality of network paths;

transacting communication traffic using a codec-network path combination having a quality of experience above a predetermined threshold;

dynamically determining a changed codec-network path combination based upon, at least in part, a determined change in quality of experience associated with one or more of the plurality of codecs and the plurality of network paths; and

transacting communication traffic using the changed codec-network path combination.

2. The computer-implemented method of claim 1, wherein analyzing network conditions includes:

transmitting emulated communication traffic for each of the plurality of codecs across each of the plurality of network paths; and

receiving performance characteristics associated with each of the plurality of codecs for each of the plurality of network paths.

3. The computer-implemented method of claim 2, wherein determining the quality of experience includes:

analyzing performance characteristics associated with each of the plurality of codecs across each of the plurality of network paths; and

determining a quality of experience score for each of the plurality of codecs across each of the plurality of network paths.

4. The computer-implemented method of claim 1, wherein determining the quality of experience includes:

identifying one of the plurality of codecs associated with a quality of experience score above a threshold as a selected codec;

identifying one of the plurality of network paths associated with a quality of experience score above the threshold as a selected network path; and

determining a codec-network path combination having a quality of experience above a predetermined threshold based upon, at least in part, the selected codec and the selected network path.

5. The computer-implemented method of claim 1, wherein transacting communication traffic includes:

transmitting an indication of a selected codec to be utilized for transmitted communication traffic to a sending participant of a communication session; and

receiving communication traffic from the sending participant, the communication traffic encoded according to the selected codec.

6. The computer-implemented method of claim 5, further including:

transmitting the communication traffic from the sending participant to a receiving participant via a selected network path.
