[e2e] High Packet Loss and TCP

David,

i'm surprised by the 30% number as it seems high.  i guess my rule of thumb 
has been that TCP might behave itself under 10%, but that over 10% you're 
unlikely to get anything decent in terms of performance.

maybe this is the difference between theory and practice (which difference is 
that in theory there is none, but in practice there is), or maybe the current 
turbo-charged TCPs (fast retransmit, etc.) really bump the performance in a 
lossy environment.

cheers, Greg Minshall
