packet loss and degraded service

Hello,
I am interested in using a “law of large numbers” approach to correlate packet loss to deviations from expected call completion rates or call durations. I have put together some Web pages (http://home.attbi.com/~sherryanderic/Teletraffic.htm) describing this and I am interested in opinions on this as an area of study.

regards,
