Increment the window size by 1/window size when a packet succeeds.
Halve it when one fails.
That's what TCP does in congestion avoidance mode (ie when cwind >
ssthresh) but it's less aggressive than what TCP does in slow start
mode, so connections will take longer to reach full speed and to
return
to full speed after a packet loss. You might not get great link
utilisation but it seems like a good compromise because it avoids the
complexity of calculating ssthresh.
If we don't already, we should also remember the window size between
the transmission of different blocks of data, rather than starting
from scratch once every 32kb block.
