In addition to erasure codes:<br>

TCP provides <i>reliable</i> transport.<br>
<br>
In the general case, you neither know your corruption ratio nor
your drop ratio. So you cannot really determine a necessary
"code strength", as you cannot predict the necessary attempts of
retransmissions. <br>
<br>
The game erasure codes vs. retransmissions seems like running in
a vicious circle to me.<br>

Hi Detlef<br>
<br>
Both are complementary for me : you are faster with ARQ over small
RTT and faster with erasure coding over long-delay link.<br>
