i suggest further reading and perhaps reconsideration. we've got to
break out of the MTU 1500 jail some day or the internet will end in
header processing related heat death. some work is being done and some
results are already known. we should be open to the possibility of
improvement.
I apologize for derailing this conversation by bringing up NAT. My point
was that the document makes a claim that PMTUD ‘remains widely
undeployed due to security issues’. Yet it makes no reference to
anything that might back up that claim. I would suggest the document not
make any claim as to why PMTUD remains widely undeployed. If it must
make such a claim then there should be some supporting evidence for it.
the claim isn't essential, but i think it's valuable to understanding.
would you accept this edit: "was never widely deployed due to perceived
security issues having to do with ICMP and IP Options"?
separately we ought to add a reference to PLPMTUD (which != PMTUD) but
that's an answer to a different part of this thread.
