Hi,

Going back to our discussions from last week, here is a draft that
captures the proposed uses of fragmentation for tunneling and other
purposes. It is called: "Fragmentation Revisited", and it offers an
approach to limited use of fragmentation in a way that can begin to
remove all barriers to supporting larger MTUs in the Internet, i.e.,
even with broken PMTUD, even with broken fragmentation/reassembly,
and even with tunnels.

Think about that for a second. While we currently have burned-in
numbers (576, 1280, 1500) that will never go away, the adoption of
these techniques will ensure that there will never again need to
be another burned-in number even as the Internet naturally grows
to support larger packet sizes. We will then be able to say that
the MTU of the Internet is "unlimited" or rather limited only by
the constituent links, whatever they happen to be. Comments on
the list would be welcome.

Thanks - Fred

	Title           : Fragmentation Revisited
	Author(s)       : Fred L. Templin
	Filename        : draft-generic-6man-tunfrag-08.txt

Abstract:
   IP fragmentation has long been subject for scrutiny since the
   publication of "Fragmentation Considered Harmful" in 1987.  This work
   cast fragmentation in a negative light that has persisted to the
   present day.  However, the tone of the work failed to honor two
   principles of creative thinking: never say "always" and never say
   "never".  This document discusses uses for fragmentation that apply
   both to the present day and moving forward into the future.
