retransmit segments that are delivered. This region has important
theoretical interest (it evades congestion collapse!) but is
irrelevant from an operational perspective (nobody want to use a
network that is so congested that the average available capacity is
measured in bits per second.)

Particularly on this one.<br>
<br>
I agree that no one wants to use a overloaded network. However, as
long as we have no actual limit for the number of flows along the
path, the situation of network overload may happen now and then.<br>
<br>
The reason why I thought about this issue at all is still that I
want to understand the buffer bloat phenomenon and the recent posts
on that matter indicate that buffer bloat could be a consequence
from network overload. Of course in combination with too large
buffers on routers/switches. However, if we want to avoid buffer
bloat and strictly encourage the use of reasonably limited buffer
space, the problem would become more obvious. Particularly as flows
wouldn't be simply "dropped" from the network but would suffer from
a huge number of packet drops / retransmissions which would throttle
the flows' goodputs.<br>
<br>
Hence throttling a flow's <i>throughput </i>may increase a flow's
<i>goodput</i>.<br>
