Re: Question about propagation and queuing delays

TCP performs much better if queueing delays are short, because that means it gets feedback from packet drops more promptly, and its RTT measurements are more accurate so the retransmission timeout doesn't get artificially inflated.

Sure, but sending speculative duplicate ack's if you're competing seriously of transit bandwidth works even better... Not sure how to set the evil bit on the packets though... Pete
