Title : Re-ECN: Adding Accountability for Causing Congestion to TCP/IP
Author(s) : B. Briscoe, et al.
Filename : draft-briscoe-tsvwg-re-ecn-tcp-00.txt
Pages : 27

This document introduces a new feedback protocol for explicit
congestion notification (ECN), termed re-ECN. It arranges the ECN
field of each packet so that, as it arrives at each router, the
relative rates of each codepoint will give a truthful prediction of
congestion on the remainder of the path. It also outlines mechanisms
at the network edge that ensure the dominant selfish strategy of both
network domains and end-points will be to set these codepoints
honestly and to respond correctly to path congestion, despite
conflicting interests. Although these mechanisms influence
incentives, they use engineering mechanisms like throttling and
dropping, rather than requiring changes to end-user pricing. The
protocol can be deployed incrementally around unmodified routers
without requiring changes to IP.

In the body type:

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.
