Art,

indeed, delay is the ultimate arbiter - but your figures left out
the lower delay paths for smaller nets (local ones). I think we
ll agree, though, that window-based schemes suffer when long delays
are involved and high speeds. The source must be tolerant of
very long relative delays before receiving acknowledgement so
hat pacing rather than buffer acks has to be the flow control
method because buffer acks come at too long delay to be an effective
low control - the loop time is too long.
