Presence and IntComm WG

[Ben Teitelbaum <>]

Samir,

This talk from the First Joint Internet2/DOE QoS Workshop in February
2000 seems highly relevant:

Objective Estimation of Video and Speech Quality to Support Network
QoS Efforts Stephen Voran and Stephen Wolf (Institute for
Telecommunication Sciences) slides (PDF), video (Real), abstract
(HTML)
http://qbone.internet2.edu/meetings/houston2000/

I recall that it was quite good.  I can't speak to what Stephen and
Stephen have been doing since.
