I'm puzzled. Can you explain what you mean by bringing to a halt? Do you mean a dropped packet might terminate the TCP connection; or at worst result in the timeout of a segment and a return to slow start? Nevertheless, I would have thought a timeout is a rare event at best, even on high latency links, due to the post-Jacobsen RTT estimator and fast retransmit kicking in at 3 duplicate ACKs?
