Abstract
The comfort noise generation (CNG) feature of current VoIP codecs leads to inaccuracies in the multiplexing performance analysis based on on-off sources. The fluid model is adapted to obtain accurate loss prediction in the multiplexing process of VoIP sources equipped with CNG and provide an algorithmic solution for its dimensioning application. Results, validated with traces, demonstrate significant improvement with respect to on-off multiplexing approaches.
