Source Quench had the problem right but the solution wrong. If a packet was
discarded because of congestion, it was not clear that the party sending
THAT packet was the source of congestion. Even if the source backed off, it
might still not be solving the problem if the real source of the congestion
was a different packet stream.

Random dropping had a better probability of "hitting" the real source of
congestion but it was still "hit or miss"

If there is a solution it may lie in monitoring specific flows - this is
something that some routers now do.
