Re: TCP performance limitations

Does anyone have pointers to work being done in the performance of
transport protocols (including TCP), when communications links are not
reliable? E.g., how do various protocols behave in the presence of
lost datagrams. I am asking this more from the theoretical point of
view than from the angle of tuning an existing implementation. For
instance, if 10% of the packets are lost, what happens to the
throughput of TCP? I realize that there are a lot of variables that go
into this, but it is still interesting to fix various parameters
while varying packet loss rate, or to observe how window size, RTT,
and packet lossage interact.
