Supporting Collaborative Audio in the Internet

Distributed Partial Mixing (DPM) is an approach to creating a distributed audio service that supports optimisation of bandwidth utilization across multiple related audio streams (e.g. from concurrently active audio sources) while maintaining fairness to TCP traffic in best effort networks. This paper extends our DPM prototype to include the application control of selector and database components of DPM as a necessary complement to purely network-driven DPM presented till now. In particular we introduce awareness driven and Interest Management driven DPM as one way of that smoothing out the effects of the network adaptation on the end user audio quality in Collaborative Environments.
