This isn't as straight forward as it sounds.  The packet losses can 
generate triple duplicate ACKs for example, and you have to manually 
figure out what's going on.  Or you may even have SACK enabled and that 
makes it more difficult to analyze.

You can get a rough idea of what's going on by looking at the first 
occurrence of retransmissions.  To be honest, I have the luxury of using 
Opnet's ACE and it can calculate stuff like this pretty easily.  Of 
course, Opnet isn't exactly cheap! ;)
