[e2e] Can feedback be generated more fast in ECN?

[David P. Reed]

The cost of packet switching equipment, much less the network's costs as a 
whole, is hardly dominated by the choice to set a bit vs. generate a packet 
in a case that should be rare if the network is being managed correctly.

Unidirectional pipes would seem to be a red herring.  All routers need to 
be able to route packets to all destinations.  There's certainly some 
unidirectional pipe that can carry a packet back to the source.  If not, 
then the network itself is unidirectional, and one cannot run TCP or any 
other closed loop protocol.

Finally, it seems to me that personal attacks are not appropriate in this 
list.  Does it really mean much that I've written hundreds of thousands of 
lines of assembly code, C code, and DSP code or designed hardware, buses 
and switches?  Or for that matter, that code I've personally written has 
been responsible for hundreds of millions of dollars of revenue if not 
more?  The merits of the argument matter much more than the qualifications 
of the author, or the disparaging tone of the writer.
