The encapsulation of IP packet headers in tunnels is used in many
places, including IPsec and IP in IP [RFC2003]. Explicit Congestion
Notification (ECN) is an experimental addition to the IP architecture
that uses the ECN field in the IP header to provide an indication of
the onset of congestion to applications. ECN provides this
congestion indication to enable end-node adaptation to network
conditions without the use of dropped packets [RFC 2481]. Currently,
the ECN specification does not accommodate the constraints imposed by
some of these pre-existing specifications for tunnels. This document
considers issues related to interactions between ECN and IP tunnels,
and proposes two alternative solutions

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
