Title : Emulating Border Flow Policing using Re-ECN on Bulk Data
Author(s) : B. Briscoe
Filename : draft-briscoe-re-pcn-border-cheat-01.txt
Pages : 54
Date : 2008-02-25
Scaling per flow admission control to the Internet is a hard problem.
A recently proposed approach combines Diffserv and pre-congestion
notification (PCN) to provide a service slightly better than Intserv
controlled load. It scales to networks of any size, but only if
domains trust each other to comply with admission control and rate
policing. This memo claims to solve this trust problem without
losing scalability. It describes bulk border policing that provides
a sufficient emulation of per-flow policing with the help of another
recently proposed extension to ECN, involving re-echoing ECN feedback
(re-ECN). With only passive bulk measurements at borders, sanctions
can be applied against cheating networks.

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
