I have to wonder if the only heuristic one could employ for divining the initial
congestion window is to be either pessimistic/conservative or
optimistic/liberal. Or for that matter the only one one really needs here?
That's what it comes down to doesn't it? At any one point in time, we don't
*really* know the state of the network and whether it can handle the load we
might wish to put upon it. We are always reacting to it. Up until now, it has
been felt necessary to be pessimistic/conservative at time of connection
establishment and not rely as much on the robustness of the "control" part of
avoidance and control.
Now, the folks at Google have lots of data to suggest we don't need to be so
pessimistic/conservative and so we have to decide if we are willing to be more
optimistic/liberal. Broadly handwaving, the "netdev we" seems to be willing to
be more optimistic/liberal in at least a few cases, and the question comes down
to whether or not the "IETF we" will be similarly willing.
