Title : Robust ECN Signaling with Nonces
Author(s) : D. Wetherall et al.
Filename : draft-ietf-tsvwg-tcp-nonce-00.txt
Pages : 9
Date : 23-Feb-01
This note describes a simple modification to ECN that protects
against accidental or malicious concealment of marked packets from
the TCP sender. This is valuable because it improves the robustness
of congestion control by preventing receivers from exploiting ECN to
gaining an unfair share of the bandwidth. The mechanism uses a
slightly different encoding than the existing two ECN bits in the IP
header, and also requires one additional bit in the TCP header. It is
computationally efficient for both routers and hosts.

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.
