Abstract
The comfort noise generation (CNG) feature of current VoIP codecs can lead to severe inaccuracies in the dimensioning analysis done through traditional models based on multiplexing on-off sources. We adapt the fluid model to obtain an accurate loss prediction in the multiplexing process of those codecs equipped with CNG. Results are validated by simulations fed with VoIP traffic traces and demonstrate a significant accuracy improvement with respect to current on-off multiplexing approaches.
