Title : Robust ECN Signaling with Nonces
Author(s) : D. Wetherall, N. Spring, D. Ely
Filename : draft-ietf-tsvwg-tcp-nonce-04.txt
Pages : 12
Date : 2002-11-4
This note describes the ECN-nonce, an optional addition to ECN that
protects against accidental or malicious concealment of marked
packets from the TCP sender. It improves the robustness of
congestion control by preventing receivers from exploiting ECN to
gain an unfair share of network bandwidth. The ECN-nonce uses the
two ECT codepoints in the ECN field of the IP header, and requires a
flag in the TCP header. It is computationally efficient for both
routers and hosts.

In the body type:
"FILE /internet-drafts/draft-ietf-tsvwg-tcp-nonce-04.txt".
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
Internet-Draft.
