I hope that people of this E2E list are reading the current thread on
the IETF list about choosing a
new Transport Area director who is/is not an expert in congestion
control. Some of you have
been around long enough to recall the congestion collapse of the
(NSF-sponsored) Internet, before
Van J showed us how to not be stupid when he defined the basic TCP CC
invented the concept of "TCP Friendly" to try to head off a race to the
bottom while providing
an easy-to-understand criterion for acceptable CC.
It seems like an interesting question for research to determine whether
of some future transport protocol with an ill-advised or inadequate CC
mechanism could still
cause congestion collapse of large areas of the Internet,or only local
patches. Or has
that been researched and I missed it?
Congestion control seems a bit like riding a unicycle -- even after you
learn how to do it,
you have to pay attention every moment or you are in danger of falling off.
