Reading the draft, I felt one missing reference -- RFC 9484, Proxying IP
in HTTP. I suppose that's a consequence of the publication hiatus.
By the way, I understand the focus on IP tunnelling, but from an
architecture point of view it would be interesting to study the spectrum
of solutions between "tunneling" and "proxying". HTTP proxying is well
established. Tor use of onion routing is another interesting data point.
The Masque WG has been working on a variety of "foo over QUIC"
solutions, besides the "IP in HTTP3" subset of RFC 9484. These include
proxying UDP in RFC 9298, proxying Ethernet in HTTP in
draft-ietf-masque-connect-ethernet, and QUIC-Aware Proxying Using HTTP
in draft-ietf-masque-quic-proxy-06. The latter includes discussion of
many of the points made in the "IP Tunnels" draft, including enabling
cascading of proxies without adding per-proxy overhead, allowing
end-to-end congestion control without interference from proxying, or
allowing end-to-end MTU discovery. The WG is still debating details,
including how to handle ECN.
Speaking of ECN, the transport area is working on the "next generation"
ECN with projects like L4S. That too seems like a missing reference.

Per the Madrid recorded presentation:
Requested by the IESG, March 2007
* First version draft-touch July 2007
* Discussions begin…
INTAREA adoption July 2010
* Significant revision 2015, with figures and revised terminology
* Another significant revision 2016, with more figures and expanded
terminology
Largely complete by 2018
* Then a hiatus due to job shift

It looks like this document became an intarea WG item in March
2010; maybe it
was ahead of its time, and the time has now arrived.

Folks,
This is an excellent overview of tunnel technology. However, I
wonder if the publication of this draft will change anyone's
behavior. If not, I wonder if the IETF stream is the right
place for this document. Maybe the independent stream is more
appropriate? Maybe the Internet Protocol Journal or a blog?
Maybe even a chapter in a textbook?
I think it should be published as an RFC as It has originally been
intended to. Unfortunately it has been (probably unnecessarily )
delayed for a long time.

Dear IntArea WG,
The authors of Draft
_https://datatracker.ietf.org/doc/html/draft-ietf-intarea-tunnels-15
<https://urldefense.com/v3/__https:/datatracker.ietf.org/doc/html/draft-ietf-intarea-tunnels-15__;!!NEt6yMaO-gk!AST0foNqNIWijq2ReXb3w8D4mUd3Sx53MI5Quv7oqyWSY5IiiLSevttp23VbJW6DPwYlIGVUjeYKV6KJK2lGv0LA3FpSqC0$>_are
requesting a WGLC. The latest draft was presented at IETF
123and we heard some comments from the floor.
Hence, we are starting now a 2-week WG Last Call. We would
like to receive at least 5 substantial reviews to move forward.
Please express your support/comments by replying to this
email. To compensate for the summer break, the call will end
on Friday the 22ndof August(AoE).
Thanks,
Juan-Carlos & Wassim
(IntArea WG chairs)
