Abstract
Techniques to optimize quality of service and quality of user experience for multi-media mobile applications are described. A traffic detection component detects the video and audio data components of a video call. Detection may be via a modified traffic detection component or via a software quality of service component exposing traffic detection component functionality to a multi-media application via an application programming interface. Based on available bandwidth for a session of the multi-media application and heuristics, video and audio data components may be placed in different contexts with different priorities. In the specific case of a video call, the video and audio data components are each associated with a quality of user experience threshold, which when available bandwidth fails to meet those thresholds, an optimizing heuristic to trigger the traffic detection component to change contexts and priorities of the video and audio data components.
