We have a paper that relates voice quality to the network performance:
J. Janssen, M.J.C Büchli, D. De Vleeschauwer and G.H. Petit, "The Impact of
Transmission Parameters on the Quality of Packet-based Telephony", Accepted for
the special issue of IEEE Internet Computing on Internet Telephony, scheduled
for May/June 2002.
This paper is based on the E-model.
We also have another one that is more or less related to your question. It also
deals with Voice only (no audio, no video)
M.J.C. Büchli, D. De Vleeschauwer, J. Janssen, A. Van Moffaert, G.H. Petit,
"Resource Allocation and Management in DiffServ Networks for IP Telephony",
Proceedings of the 11th International Workshop on Network and Operating Systems
Support for Digital Audio and Video (NOSSDAV01), pp. 33-39, Port Jefferson (NY),
25-26 June 2001.
We are currently extending this study for video/audio.
Kind regards,
Danny
