You guys have obviously done a lot of work on this, however, it seems
that there is a case for introducing some heuristics into the choice of
init cwnd as well as offering the option to go larger? An initial size
of 10 packets is just another magic number that obviously works with the
median bandwidth delay product on today's networks - can we not do
better still?
Seems like a bunch of clever folks have already suggested tweaks to the
steady stage congestion avoidance, but so far everyone is afraid to
touch the early stage heuristics?
Also would you guys not benefit from wider deployment of ECN? Can you
not help find some ways that deployment could be increased? At present
there are big warnings all over the option that it causes some problems,
but there is no quantification of how much and really whether this
warning is still appropriate?
