Re: Congestion problems

Nicely stated.

By the way, Paul Tsuchiya, Joe Lawrence and I had quite a debate
over the relative importance of trying to squelch traffic at
the source when congestion is being experienced in the network
supporting SMDS.  They have some pretty convincing arguments 
that suggest that if you cannot MAKE the traffic sources behave,
there is little benefit to attempting to localize the penalty
(i.e., discarding) to the noisiest sources, and that the overhead
and complexity required to put such a system in place may be
greater than its worth.  So, it may be worthwhile revisiting our
recent thinking.  I guess I made some assumptions that relied on
some transport layer behaviors that wouldn't take effect without
explicit feedback mechanisms, sorry.
